The 1.5KE15A/54 is listed as obsolete by Vishay General Semiconductor. No official successor order code is recorded in the lifecycle data. ## Temperature and mounting constraints The junction operating temperature range spans -55°C to +175°C, covering industrial and some automotive under-hood thermal profiles. The axial DO-201AA package is through-hole mounted, requiring a drilled PCB with lead spacing matching the body length. This part does not include power line protection circuitry — it is a standalone transient suppressor for signal or low-power DC rail clamping, not a primary AC mains protector.","metaTitle":"Vishay 1.5KE15A/54 TransZorb TVS, 1500W, 12.8V Standoff","metaDescription":"Obsolete Vishay 1.5KE15A/54 TransZorb Zener TVS diode. 1500W peak pulse, 12.8V reverse standoff, 21.2V clamp.
