Its 50 ns reverse recovery time suits it for high-frequency rectification, snubber clamping, and flyback catch-diode roles where a standard 1N4148 would be too slow or lack the voltage headroom. This part carries AEC-Q101 qualification, meaning it has passed the automotive-grade stress tests for temperature cycling, humidity, and high-temperature reverse bias. It is intended for under-hood and chassis-domain electronics where the junction temperature can reach 150 °C maximum. Reverse leakage is 100 nA at 200 V, a figure that rises with junction temperature but stays within the guard band for most automotive sensor and actuator interfaces. ## SOD-323 footprint and assembly considerations The SOD-323 package (SC-76) has a 1.7 mm × 1.25 mm body with gull-wing leads on 1.25 mm pitch. The small footprint suits dense PCB layouts, but the copper pad area under the cathode tab sets the thermal resistance — a solid ground-plane connection is recommended for designs running near the 250 mA continuous rating. The part is supplied in Tape & Reel (TR) or Cut Tape (CT) options, compatible with standard pick-and-place equipment. No official successor or second-source cross-reference is listed; for dual-sourcing, evaluate Vishay's own BAV21WS series siblings with the same SOD-323 footprint.","metaTitle":"BAV21WS-HE3-08 Diode, 200V 250mA Fast Recovery SOD-323","metaDescription":"BAV21WS-HE3-08 general-purpose fast recovery diode, 200V reverse, 250mA forward, 50ns trr.
