A downstream DC-DC converter or ECU with a 40 V abs-max input rating has 2.5 V of headroom above the clamp. ## DO-214AB (SMC) package and reel storage Housed in the standard DO-214AB (SMC) surface-mount package, the diode occupies the same footprint as other 1.5 kW TVS devices in this form factor. The cathode band is marked for orientation; the bidirectional variant has no polarity and can be placed in either direction. Supplied on Tape & Reel, the reels should be stored in a dry environment per JEDEC MSL level — the DO-214AB body is not hermetic, and moisture absorbed during storage can cause package cracking during reflow.","metaTitle":"Vishay 1.5SMC27CAHM3_A/H TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5SMC27CAHM3_A/H automotive TVS diode, 1500W peak pulse, 23.1V standoff, 37.5V clamp, AEC-Q101, DO-214AB.
