When a surge exceeds the 503.5V minimum breakdown voltage, the diode clamps the transient to 725V maximum while shunting 2.1A of peak pulse current in the 10/1000µs waveform — enough for most industrial surge environments. ## Thermal and package fit Rated for continuous junction temperatures from -55°C to 175°C, this part suits equipment that sees hot ambient conditions — motor drives, power supplies, or outdoor telecom gear where the enclosure temperature can climb. The DO-201 (DO-27) axial-lead package is a through-hole form factor; it solders into a board with standard wave or hand-soldering profiles and handles the 1500W (1.5kW) peak pulse power without derating at 25°C lead temperature.","metaTitle":"Littelfuse 1.5KE530A-B TVS Diode, 503.5V Breakdown","metaDescription":"Littelfuse 1.5KE530A-B Zener TVS, 1500W peak pulse, 451V reverse standoff, 725V clamping.
