The 1.5kW peak pulse power rating tells you it can handle a substantial surge — think industrial power supplies, telecom rectifiers, or motor-drive DC buses — without the part failing short. It is housed in a DO-214AB (SMC) package, surface-mount, and supplied on Tape & Reel. ## What the Clamping and Breakdown Specs Mean for Your Board The minimum breakdown voltage is 100V. If your rail sits at 90V nominal, the TVS stays off during normal operation. When a transient pushes the line above 100V, the diode starts to avalanche, and at 146V it clamps the pulse to 10.3A. That 146V ceiling is the number to check against the downstream components' absolute maximum ratings — if your DC-DC converter's input rating is 150V, you have 4V of margin. Available on Tape & Reel in DO-214AB.

It protects against positive transients referenced to ground.
