SA58A Description

Short technical summary and product information.

The SA58A is a 500W transient voltage suppression (TVS) diode from Littelfuse's SA series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. The device offers a reverse standoff voltage of 58V and a clamping voltage of 93.6V at a peak pulse current of 5.4A (10/1000μs waveform).

 

Key specifications include a peak pulse power dissipation of 500W, fast response time typically less than 1.0ps, and low leakage current (<1μA for VBR max >13V). The SA58A is unidirectional and features a glass passivated chip junction for reliability. It also provides ESD protection up to 30kV (air and contact discharge) per IEC 61000-4-2.

 

The device is housed in a DO-204AC (DO-15) axial leaded package with through-hole mounting. It is RoHS compliant, halogen free, and has a flammability rating of V-0. The operating temperature range is -55°C to 175°C. Typical applications include protection of I/O interfaces, VCC bus, and other circuits in telecom, computer, industrial, and consumer electronics.
