Product Description
Littelfuse SMCJ400CA is a high performance 1-element bi-directional transient voltage suppression (TVS) diode designed to protect sensitive electronics against voltage surges and transients. It operates with a peak pulse power dissipation of 1.5 kW, making it suitable for robust industrial and commercial applications requiring reliable overvoltage protection. The diode is housed in a compact 2-pin DO-214 surface mount package for ease of integration on printed circuit boards.
This TVS diode has a minimum breakdown voltage of 447 V and can withstand a maximum reverse stand-off voltage of 400 V. It provides a clamping voltage of 648 V to safely shunt excessive transient currents and prevent damage to downstream components. The bi-directional design enables protection of circuits subject to voltage spikes of both polarities.
With an operating temperature range from -65 °C to 150 °C, the Littelfuse SMCJ400CA TVS diode is engineered for durability and reliability in harsh environments such as industrial controls, automotive electronics, power supplies, and telecommunications. Its low maximum reverse leakage current of 1 μA reduces leakage losses and improves circuit efficiency.
The diode’s physical dimensions, 2.417 mm in height, 7.11 mm in length, and 6.22 mm in width, make it suitable for compact designs requiring effective transient voltage suppression without added bulk.
Designed for transient voltage suppression in electronic circuits. Bi-directional diode configuration for versatile protection. Surface mount DO-214 package for compact PCB layouts. High peak pulse power dissipation of 1.5 kW and peak pulse current of 2.3 A.
