SA30A Description

Short technical summary and product information.

The SA30A is a unidirectional TVS diode from Littelfuse designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 30V and a clamping voltage of 48.4V, with a peak pulse power dissipation of 500W (10/1000μs waveform). The device offers a peak pulse current of 10.5A and a peak forward surge current of 70A (8.3ms).

 

This TVS diode is housed in a DO-204AC (DO-15) through-hole package with axial leads and matte tin lead-free plating. It operates over a temperature range of -55°C to 175°C and is suitable for general-purpose transient voltage suppression in telecom, computer, industrial, and consumer applications.

 

The SA30A is RoHS compliant, halogen free, and has a fast response time of less than 1.0ps. It is designed for I/O interface protection, VCC bus protection, and other vulnerable circuits.
