High-Performance Schottky Diode for Automotive Applications
STMicroelectronics' STPS2H100AY Schottky Diode represents a significant advancement in power electronics for automotive systems. Designed specifically for the Q Automotive series, this 100V 2A diode combines cutting-edge semiconductor technology with robust reliability metrics required by modern vehicle electrical architectures. The DO-214AC (SMA) surface-mount package integrates seamlessly into high-density PCB layouts while maintaining exceptional thermal performance under demanding operating conditions.
Technical Specifications and Electrical Characteristics
Operating at the intersection of speed and efficiency, this Schottky diode demonstrates impressive electrical parameters. With a maximum reverse voltage of 100V and 2A average rectified current capacity, its forward voltage drop remains exceptionally low at 790mV when conducting 2A. This low Vf characteristic significantly reduces conduction losses, making it ideal for power-sensitive automotive applications. The device maintains minimal reverse leakage current (1µA at 100V) while operating across the full automotive temperature range of -40°C to 175°C.

| Forward Current | 2A |
| Forward Voltage Drop | 790mV @ 2A |
| Reverse Leakage | 1µA @ 100V |
| Mounting Type | Surface Mount |
The component's fast recovery characteristics (<= 500ns) enable efficient operation in high-frequency switching circuits commonly found in automotive power supplies and motor control systems. This rapid switching capability makes it particularly suitable for DC-DC converters in vehicle infotainment systems and LED lighting controllers where efficiency and space conservation are critical.
Automotive System Integration Advantages
The STPS2H100AY's AEC-Q101 qualification ensures compliance with automotive industry reliability standards, making it suitable for critical applications in engine control units, battery management systems, and onboard charging circuits. Its SMA package provides excellent mechanical stability during thermal cycling, a crucial factor in automotive environments experiencing extreme temperature variations.
When compared to conventional silicon diodes, this Schottky device offers several advantages: reduced forward voltage drop improves energy efficiency, faster recovery time minimizes switching losses, and the surface-mount configuration allows for automated PCB assembly processes. These benefits collectively contribute to enhanced system reliability and lower total cost of ownership in automotive manufacturing.
