The reverse standoff voltage is 24.3 V; the device remains transparent below this threshold. This means a 24 V automotive rail sees no clamping during normal operation, but a load-dump or alternator-field decay transient that pushes the line above 27 V is shunted to 43.5 V or less — within the safe operating area of downstream 60 V-rated ECUs and sensors. Operating temperature range spans -55°C to +175°C. The 175°C junction rating is the key number for an engine-bay or exhaust-adjacent location — it provides margin above the 150°C cap of many TVS diodes in the same power class. ## Package and board integration — DO-201AA axial lead Supplied in a DO-201AA (DO-27) axial leaded package, through-hole mount. The axial body is rated for the full 1.5 kW pulse without derating — the leadframe and body geometry handle the thermal pulse energy without the junction exceeding 175°C. Board layout requires adequate copper pad area at the solder joint to manage the heat sink path; the lead spacing matches standard 0.4-inch pitch PCB hole patterns for transient protection arrays.","metaTitle":"Vishay 1.5KE30CHE3/54 TVS, 27V Breakdown, 1.5kW","metaDescription":"Obsolete Vishay 1.5KE30CHE3/54 bidirectional Zener TVS diode, 1500W peak pulse, AEC-Q101 qualified, 24.3V standoff.
