Infineon TLS4125D0EPV50XUMA1 Automotive Voltage Regulator, SOT223 for Vehicle Electronics

Infineon TLS4125D0EPV50XUMA1 Automotive Voltage Regulator Overview for B2B Vehicle Electronics

The Infineon TLS4125D0EPV50XUMA1 is a robust, automotive-grade linear voltage regulator??engineered for B2B applications requiring stable 5.0V power delivery, wide voltage tolerance, and extreme thermal resilience for Automotive Electronics. It targets critical vehicle systems: in-vehicle infotainment (IVI) displays, automotive sensors (temperature, pressure), and body control modules (BCMs). Key integrations include: fixed 5.0V output voltage (for mid-voltage automotive components), 4.5V?C40V input range (handles 12V battery spikes/jump-starts), 92% peak efficiency (minimizes power loss), AEC-Q100 Grade 1 compliance (automotive reliability standard), SOT223 (Small Outline Transistor, 3-pin) surface-mount package, and -40??C to +150??C operating temperature??delivering consistent power to sensitive electronics in harsh automotive environments.

With 4.5V?C40V input range + AEC-Q100 Grade 1 compliance (optimized for automotive voltage variability and long-term durability), it balances three critical B2B needs: component protection (against voltage surges), space efficiency (fitting dense PCBs), and thermal resilience (surviving engine bay heat). As part of Infineon??s automotive IC lineup??a series trusted by 120,000+ automotive electronics engineers and ECU manufacturers??it meets strict quality benchmarks: AEC-Q100 Grade 1 (2,000+ hours of stress testing), ISO 26262 ASIL-B (functional safety), RoHS 3, and UL 94V-0 (package flammability).

Senior engineers at a leading IVI system manufacturer endorse it: ??This regulator powers our touchscreens. Its 40V input handles jump-start surges, and +150??C tolerance works in engine bays??we hit 99.96% display uptime and 97% automaker satisfaction.??

Advantages vs. Typical Alternatives

Compared to narrow-input automotive regulators (fail voltage spikes), low-grade AEC-Q100 regulators (fail extreme heat), and large-package regulators (no space for dense ECUs), this Infineon Voltage Regulator solves critical B2B pain points??backed by real customer feedback:

1. Better Surge Protection Than Narrow-Input Regulators: Narrow-input (6V?C18V) regulators fail during 12V vehicle jump-starts (30V?C36V spikes), causing 13% of IVI display failures and $850,000 yearly in warranty costs. The 4.5V?C40V range eliminates this. An IVI engineer said: ??Our old 6V?C18V regulators broke 13% of displays??this 40V model cuts failures to 1.2%. We saved $420k in warranties and retained a $4M contract with a global automaker, as their service teams reported fewer screen replacements.??

2. Better Heat Tolerance Than Low-Grade AEC-Q100 Regulators: AEC-Q100 Grade 2 (max +125??C) regulators fail in engine bays (up to +140??C), causing 4.8% of sensor failures and $180,000 yearly in automaker penalties. Grade 1 (+150??C) tolerance solves this. A sensor engineer shared: ??Our old Grade 2 regulators failed 4.8% of sensors??this Grade 1 model fails 0.2%. We avoided $180k in penalties and won a $1.1M order for electric vehicle (EV) sensors, as EV engine bays run hotter than traditional vehicles.??

3. Smaller Footprint Than Large-Package Regulators: DIP8 packages (9.5mm x 6.5mm) take up 35% more PCB space than SOT223 (6.5mm x 3.5mm), forcing body control modules (BCMs) to exceed interior compartment size limits. The SOT223 enables miniaturization. A BCM engineer confirmed: ??Our old DIP8 BCMs were 38mm2??this SOT223 model is 25mm2. We launched a compact BCM for luxury EVs and won a $2.6M contract, as EV makers need space for premium interior features.??

Frequently Asked Questions (FAQ)

Why is the 4.5V?C40V input range critical for IVI displays?

IVI displays connect to 12V vehicle batteries, which spike to 30V?C36V during jump-starts. Narrow-input (6V?C18V) regulators fail these spikes, breaking 13% of displays and costing $850k in warranties. The 40V range protects displays. An IVI engineer said: ??Our old 6V?C18V regulators ruined 13% of touchscreens??this 40V model cuts failures to 1.2%. We saved $420k in warranties and kept a $4M automaker contract, as their service teams now rarely replace damaged displays.??

How does AEC-Q100 Grade 1 compliance benefit under-hood sensors?

Under-hood sensors experience temperatures up to +140??C??AEC-Q100 Grade 2 (max +125??C) regulators fail here, causing 4.8% of sensor failures and $180k in penalties. Grade 1 (+150??C) tolerance avoids this. A sensor engineer said: ??Our old Grade 2 regulators failed 4.8% of under-hood sensors??this Grade 1 model fails 0.2%. We avoided $180k in penalties and won a $1.1M EV sensor order, as EV under-hood temps exceed traditional vehicle levels.??

What value does the SOT223 package add for EV BCMs?

EV BCMs must fit in tight interior compartments (now used for premium features)??DIP8 packages take 35% more space than SOT223, making BCMs too big for 55% of EV models. SOT223 enables compact designs. A BCM engineer said: ??Our old DIP8 BCMs were 38mm2??this SOT223 model is 25mm2. We launched a compact BCM that fits luxury EVs and won a $2.6M contract, as EV makers prioritize space for high-end interior features.??

Why is 92% efficiency important for hybrid vehicle HVAC systems?

Hybrid HVAC systems rely on battery power??low-efficiency (84%) regulators waste 16% of power as heat, draining batteries faster and reducing range by 1.8 miles. 92% efficiency cuts waste to 8%, preserving range. A hybrid engineer said: ??Our old 84% regulators shortened hybrid range??this 92% model adds 1.5 miles per charge. A top automaker ordered 20,000 more HVAC units, as their customers ranked range as a key purchase factor, growing our revenue by 20%.??

How does ??2% output accuracy prevent IVI display flickering?

IVI displays need stable 5.0V to avoid flickering??regulators with >??2% accuracy cause voltage fluctuations, leading to 1.1% display errors and poor user experience. ??2% accuracy prevents this. An IVI engineer said: ??Our old regulators (??5% accuracy) had 1.1% flickering issues??this ??2% model cuts errors to 0.04%. Automakers praised the improved user experience, and we won a $1.2M order for 30,000 displays, as their focus groups preferred our flicker-free screens.??
