Description
The SMBJ 40CA is a high-performance Transient Voltage Suppression (TVS) diode specifically engineered to safeguard sensitive electronic equipment from damaging voltage transients. Whether caused by lightning strikes, inductive load switching, or electrostatic discharge (ESD), this diode provides a robust shield to maintain system integrity.
Featuring a 600W peak pulse power capability, the SMBJ 40CA offers excellent clamping characteristics and low incremental surge resistance. Its ultra-fast response time—typically less than 1.0ps from 0V to BV min—ensures near-instantaneous protection against high-voltage spikes. Housed in a compact surface-mount package with built-in strain relief, it is designed for both durability and ease of integration into modern PCB layouts. This product is Halogen-free and RoHS-compliant, meeting critical environmental and quality standards. This pack of 2 units is an ideal choice for localized circuit protection and repair work.
