1500 W peak pulse, 171 V standoff — TVS for 170 VDC rails
The Panjit 1.5KE200A_R2_00001 is a 1500 W Zener TVS diode in the 1.5KE series, designed to clamp transients on DC rails up to 171 V reverse standoff. The breakdown voltage range starts at 190 V minimum, and the clamping voltage at the 5.5 A peak pulse current (10/1000 µs waveform) is 274 V maximum.
DO-201AE axial package — through-hole board fit
Housed in a DO-201AE axial-lead package, the 1.5KE200A_R2_00001 mounts through-hole. The junction temperature range spans -65°C to +175°C, covering industrial and automotive under-hood environments without derating concerns. The single unidirectional channel protects one rail; for bidirectional or AC-line clamping, two devices back-to-back or a dedicated bidirectional TVS would be needed. Power line protection is not supported — this is a data-line or DC-bus suppressor, not a mains surge protector.
