The SMCJ series are TRANSILTM diodes specifically designed for protecting sensitive equipment against transient overvoltages. Transil diodes provide high overvoltage protection by clamping action. Their instantaneous response to transient overvoltages makes them particularly suited to protect voltage sensitive devices such as MOS Technology and low voltage supplied IC’s.
The SMCJ series TRANSIL™ diodes are designed to protect sensitive equipment from transient overvoltages. They offer high peak pulse power, a wide stand‑off voltage range, and fast response times, making them suitable for MOS technology and low‑voltage ICs.
The datasheet lists absolute maximum ratings, thermal resistances, detailed electrical characteristics for each model, and mechanical packaging information including dimensions, footprint, and standard tape‑and‑reel packaging.
