When a surge hits, the diode clamps at 219 V max, shunting 6.8 A of peak current away from sensitive downstream electronics. The bidirectional channel handles both positive and negative transients, so polarity doesn't matter during installation — one less thing to check when you're swapping parts on a dead board. No official successor is recorded from Vishay. For a pin-compatible replacement, look for a bidirectional TVS in the same DO-201AA (DO-27) axial package with a 136 V standoff and 1500 W rating — the 1.5KE series footprint is standard, so several manufacturers offer functional equivalents. ## Automotive-grade transient protection The through-hole DO-201AA axial package is easy to hand-solder or wave-solder into a PCB or terminal block — no special reflow profile needed. The bulk packaging suits low-volume repair or prototyping runs.","metaTitle":"1.5KE160CAHE3/51 TVS Diode, 1500W, Bidirectional, DO-201AA","metaDescription":"Vishay 1.5KE160CAHE3/51 bidirectional TVS, 1500W peak pulse, 136V standoff, AEC-Q101.
