Minimum breakdown sits at 22.2 V, so the device does not turn on prematurely at the rail voltage. When a transient exceeds that threshold, the clamp limits the peak to 32.4 V, giving a clamping ratio of roughly 1.6× over the standoff — tight enough to protect sensitive circuits without excessive let-through. Bidirectional single-channel operation means it clamps both polarities from one part — no need to stack two unidirectional devices. ## P600 axial through-hole package The P600 axial package mounts through-hole on a PCB, which simplifies board assembly and gives a robust leaded form factor for environments where vibration or thermal cycling stresses surface-mount solder joints. The Tape & Reel and Cut Tape packaging options support both high-volume assembly and low-quantity prototyping runs.","metaTitle":"Littelfuse 5KP20CA TVS Zener, 5kW Peak Pulse","metaDescription":"Littelfuse 5KP20CA Zener TVS diode, 5kW peak pulse, 20V standoff, 22.2V min breakdown, 32.4V clamping at 157.4A.
