Littelfuse 1-Element Bi-Directional TVS Diode 400W, 2-Pin DO-214 SMAJ30CA

Littelfuse SMAJ30CA is a 1-element bi-directional transient voltage suppression (TVS) diode delivering 400 W peak pulse power in a compact 2-pin DO-214 surface mount package. This diode offers robust protection against transient voltage spikes, making it ideal for safeguarding sensitive electronic equipment in industrial, automotive, and commercial electronics applications.

The diode features a single element configuration and supports bi-directional voltage suppression, effectively protecting circuits from voltage surges in both directions. It has a minimum breakdown voltage of 33.3 V and a maximum reverse stand-off voltage of 30 V, with a low clamping voltage of 48.4 V to limit peak voltages during transient events.

Designed for harsh environments, the SMAJ30CA TVS diode operates reliably within a wide temperature range from -65°C to 150°C. It can withstand a maximum peak pulse current of 8.3 A, providing reliable surge handling capability. The device’s very low maximum reverse leakage current of 1 µA minimizes power loss during normal operation.

Compact dimensions allow high-density PCB layouts, measuring approximately 4.5 mm in length, 2.79 mm in width, and 2.087 mm in height. Surface mount packaging facilitates automated assembly and integration across various industrial sectors including power supplies, communication networks, and control systems.

ESD protection capability ensures sensitive components remain safe from electrostatic discharge damage, contributing to improved product reliability and longevity. The device does not carry specific certifications but meets Littelfuse’s robust quality standards.
