Qualified to AEC-Q101, the part carries the full automotive stress screen — temperature cycling, high-temperature reverse bias, and humidity bias — making it suitable for under-hood DC-DC stages, alternator rectifiers, and OR-ing diodes on 12 V and 48 V bus rails where the ambient temperature reaches 125 °C and the junction must survive 175 °C. ## Junction temperature and leakage trade-off The fast-recovery switching speed (under 500 ns) is typical for a Schottky — no stored charge to sweep out — so the reverse-recovery loss is negligible compared to a fast-recovery pn diode. This matters for the converter dead-time: the diode's turn-off is limited by junction capacitance, not carrier lifetime. ## TO-277A package — footprint and thermal pad The TO-277A (SMPC) package is a 3-lead PowerDFN with an exposed die-attach paddle on the bottom. The paddle is the cathode common terminal and the primary heat path; the PCB copper area under the package directly sets the junction-to-ambient thermal resistance. A 1-inch-square copper pour on the top layer, with vias to an inner ground plane, keeps the junction below 150 °C at the rated 2.8 A per diode in a 85 °C ambient. No special bake-out is needed if the sealed reel is opened within the floor-life window. The AEC-Q101 qualification is maintained on the current die and assembly line, so the part is valid for both new automotive designs and production replenishment.","metaTitle":"V4P22CHM3/H Vishay Schottky Diode, 200V, 2.8A, AEC-Q101","metaDescription":"V4P22CHM3/H Vishay Schottky rectifier, 200 V reverse, 2.8 A per diode, AEC-Q101 qualified.
