It is suited for 12 V and 24 V battery-line protection in engine bay or chassis-mounted ECUs where the reverse-standoff voltage sits well above the nominal bus. With a breakdown voltage minimum of 77.9 V and a clamping ceiling of 113 V at 13.9 A, the 1.5KE82CAHB0G protects a 70 V bus from load-dump and inductive-kick transients. The 1500 W peak pulse rating is the energy the diode can absorb in a single 10/1000 µs event — enough for ISO 7637-2 pulse 5a/b on a 24 V system without an external series resistor. The bidirectional configuration means a single device clamps both positive and negative surges — no need for a series diode or second TVS for reverse-polarity events. This simplifies the PCB layout and reduces component count on the 70 V rail. AEC-Q101 qualification is the automotive discrete reliability standard — it certifies the part for PPAP-level production in safety- and mission-critical ECUs. No official pin-compatible second source is recorded in this family, so the BOM should carry this exact order code for design-in.","metaTitle":"1.5KE82CAHB0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE82CAHB0G bidirectional TVS diode, 1500W peak pulse, 70.1V standoff, AEC-Q101 automotive grade.
