Bidirectional Zener TVS, 33.3V standoff, 1.5 kW peak pulse
The 1.5KE39CAE3/TR13: With a breakdown voltage of 37.1 V minimum and a clamping voltage of 53.9 V at 28 A peak pulse current (10/1000 µs waveform), it shunts a 1500 W peak pulse without the part failing open or short.
Housed in a DO-201AA axial-lead package (CASE-1), this part is a through-hole mount — you solder the leads into plated through-holes on the board. The junction temperature range spans -65°C to 150°C, so it handles the thermal swing of outdoor or industrial enclosures without derating at the cold end.
