Active 1500W TVS — 171V Standoff, 274V Clamp
The 1.5KE200ABULK: The 171V reverse standoff voltage means this device sits across a 150-170V DC rail without conducting leakage current under normal operation. When a transient exceeds the 190V minimum breakdown threshold, the diode clamps the surge to 274V maximum, protecting downstream semiconductors rated for at least 300V.
The -65°C to 175°C operating junction temperature range covers industrial, telecom, and outdoor equipment where the ambient temperature swings from cold start to self-heating under surge.
DO-201 Axial Package — Through-Hole Board Fit
The DO-201AA / DO-27 axial-lead package with supplier device package DO-201 is a standard through-hole footprint. The unidirectional channel has a cathode band for polarity marking; the anode lead connects to the rail being protected, cathode to ground. Supplied in bag packaging — suitable for hand-insertion or low-volume assembly. The through-hole form factor allows easy rework and visual inspection, preferred in prototype and MRO environments where board spins are common.
