The V15K150CHM3/H is a 15 A, 150 V trench Schottky rectifier from Vishay, housed in a FlatPAK 5x6 (8-PowerTDFN) package. It uses a common-cathode pair of diodes, each rated for 3.2 A average rectified current, giving a total package capability of 15 A when both diodes share the load. Reverse leakage at 150 V is 300 µA, which doubles roughly every 10 °C above 25 °C junction; at 125 °C the leakage can dominate the thermal budget if the load is light. The diode is rated as fast recovery (under 500 ns at >200 mA), which suits the switching frequencies seen in automotive DC-DC converters and alternator rectifier stages. The 150 V reverse voltage gives margin for 12 V and 24 V systems where load-dump transients can reach 60–80 V.
Automotive qualification and deployment context
The V15K150CHM3/H carries AEC-Q101 qualification, the automotive-grade stress test for discrete semiconductors. This means it has passed the full suite of reliability screens — high-temperature reverse bias, temperature cycling, and ESD robustness — for use in under-hood and chassis-domain electronics where ambient temperatures reach 125 °C. The FlatPAK package's exposed pad helps pull heat into the PCB copper, which is critical for the 150 °C max junction limit.
Sourcing and compliance documentation
Vishay provides RoHS and REACH compliance documentation for this part number. The FlatPAK package is halogen-free per IEC 61249-2-21. No UL or IEC safety certification applies to discrete Schottky diodes as they are not safety-critical isolation components.
