Working Principles

The SMCJ100CA operates based on the principle of avalanche breakdown. When a transient voltage spike occurs, the diode rapidly switches into its low-impedance state, shunting the excess current away from the protected circuitry. This action effectively limits the voltage across the protected components.

Detailed Application Field Plans

The SMCJ100CA is widely used in various electronic systems, including: - Power supplies - Telecommunication equipment - Automotive electronics - Industrial control systems - Consumer electronics
