The 1.5SMBJ15A: Its 15 V reverse standoff voltage (VRWM) and 24.4 V clamping voltage at 61.5 A peak pulse current make it a fit for protecting 12 V and 15 V rails in automotive and industrial power buses.
The 1.5SMBJ15A carries AEC-Q101 qualification, meaning it has passed the stress tests required for automotive-grade discrete semiconductors — temperature cycling, high-temperature reverse bias, and ESD sensitivity screening. The operating junction temperature range spans -55°C to 150°C, covering under-hood and engine-bay thermal profiles.
