Littelfuse SMAJ58A is a 1-Element Uni-Directional TVS Diode designed for transient voltage suppression in electronic circuits. Rated for a peak pulse power dissipation of 400W, this diode is available in a compact 2-pin DO-214 surface mount package ideal for PCB assembly in advanced electronic applications.
It features a minimum breakdown voltage of 64.4V and a maximum reverse stand-off voltage of 58V, providing effective protection against voltage spikes and transient surges. The clamping voltage of 93.6V ensures fast response to transient events minimizing potential device damage.
The SMAJ58A operates reliably in a wide temperature range from -65°C up to 150°C, making it suitable for industrial, automotive, and commercial electronics applications requiring robust transient voltage protection.
Additional electrical characteristics include a maximum peak pulse current of 4.3A, test current of 1mA, and a very low maximum reverse leakage current of 1μA, ensuring minimal impact on normal circuit operation while providing essential surge protection.
This TVS diode incorporates electrostatic discharge (ESD) protection as part of its design, making it effective against static and surge damage commonly encountered in electronic circuitry. The single element configuration simplifies design integration for uni-directional transient voltage suppression needs.
This diode is suitable for protecting sensitive electronics in industrial control systems, power supplies, automotive electronics, and consumer devices. The package type DO-214 with compact dimensions facilitates efficient PCB layout and soldering process.
Compliance with no specific standards or automotive certifications noted, but proven reliability for general SMT transient suppression. Explore more Littelfuse TVS Diodes and related semiconductor components at EnvMart for industrial and commercial electronic protection solutions.
