What the 1500W rating means for your protection design
The 1.5KE16: At that power level, the clamping voltage reaches 23.63V max at a peak pulse current of 67.6A — this is the voltage your downstream circuitry must survive during a transient event. The reverse standoff voltage is 13.6V, meaning the diode will not conduct appreciably below that level during normal operation. Breakdown starts at a minimum of 14.4V, so the protection triggers cleanly above the working rail voltage.
Package and board-fit: DO-201 axial through-hole
Housed in a DO-201AA / DO-27 axial leaded package, the 1.5KE16 is a through-hole part suited for board-level transient protection where wave-solder or hand-solder assembly is the norm. The DO-201 body is larger than the smaller DO-41 or SMA packages, handling the 1500W pulse without thermal fatigue. A single unidirectional channel covers one signal or power rail. For bidirectional protection, two diodes in anti-series are needed.
Temperature range and deployment environment
The wide TJ range means the clamping performance and leakage remain stable across temperature swings.
