Obsolete — sourcing through independent channels
Diodes Incorporated lists the 1.5KE16A-T as Obsolete.
1500 W peak pulse — what the rating means for the board
The 67 A peak pulse current at the 22.5 V clamping voltage defines the surge-handling capacity — a transient that pushes the clamp above 22.5 V at 67 A exceeds the device's safe operating area. The reverse standoff voltage is 13.6 V, meaning the TVS draws negligible leakage below this rail. Breakdown occurs at 15.2 V minimum, so a 12 V or 13.6 V supply rail stays protected without the TVS conducting during normal operation.
DO-201 axial — through-hole integration
Packaged in a DO-201AA / DO-27 axial leaded body, with the supplier device package designated DO-201. Through-hole mounting — the leads insert into plated through-holes and are soldered on the opposite side. The axial format suits point-to-point wiring or PCB layouts where the TVS bridges a trace pair. Operating temperature range is -55°C to +175°C, covering the full industrial and automotive ambient envelope. The junction temperature ceiling of 175°C is typical for silicon TVS diodes; derate the peak pulse power above 25°C per the datasheet curve.
