SA120C Description

Short technical summary and product information.

The Littelfuse SA120C is a bidirectional transient voltage suppression (TVS) diode from the SA series, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It offers a peak pulse power dissipation of 500W (10/1000μs waveform) and features a reverse standoff voltage of 120V with a breakdown voltage of 202.65V. The device provides IEC-61000-4-2 ESD protection up to 30kV (air and contact) and is suitable for general-purpose applications.

 

This TVS diode is housed in a DO-204AC (DO-15) axial-leaded through-hole package, making it easy to integrate into circuit boards. It operates over a junction temperature range of -55°C to 175°C and features a fast response time of less than 1.0ps from 0V to breakdown voltage. The SA120C is RoHS compliant and halogen free, meeting modern environmental standards.

 

Typical applications include protection of I/O interfaces, VCC bus lines, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The bidirectional configuration allows it to clamp both positive and negative transients, simplifying design in AC or bipolar signal lines.
