SMDJ85CA Description

Short technical summary and product information.

The SMDJ85CA is a bidirectional Zener TVS diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 85V, a minimum breakdown voltage of 94.4V, and a maximum clamping voltage of 137V at the peak pulse current of 21.9A (10/1000µs waveform). With a peak pulse power rating of 3000W, it provides robust transient protection for general purpose applications.

 

The device is housed in a surface mount DO-214AB (SMC) package, suitable for automated assembly. It operates over a junction temperature range of -65°C to 150°C and can withstand peak forward surge currents up to 300A (8.3ms). The SMDJ85CA is halogen free and lead free (Pb-free E3), complying with RoHS and REACH requirements.

 

Typical applications include I/O interfaces, VCC bus protection, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The SMDJ series is recognized under UL file E230531.
