5.0SMDJ40CA Description

Short technical summary and product information.

5.0SMDJ40CA is a 5000W bidirectional TVS diode from Littelfuse designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. With a reverse standoff voltage of 40V and a clamping voltage of 64.5V at 77.6A peak pulse current, it offers robust protection for I/O interfaces and VCC buses in telecom, computer, industrial, and consumer applications.

 

The device features a fast response time of less than 1.0 ps from 0V to breakdown voltage minimum and provides ESD protection up to 30kV air and contact per IEC 61000-4-2. The Zener technology ensures reliable clamping, and the glass passivated chip junction enhances durability. The DO-214AB (SMC) surface mount package allows for compact PCB layouts with low profile.

 

Key thermal characteristics include an operating junction temperature range of -65°C to 150°C and storage range of -65°C to 175°C. The device is halogen-free and RoHS compliant, meeting industry environmental standards. Typical failure mode is short circuit from over-specified voltage or current, providing fail-safe protection.
