TPSMA6L12A Description

Short technical summary and product information.

The TPSMA6L12A is a 600W peak pulse power unidirectional TVS diode from Littelfuse, part of the TPSMA6L series. It is designed to protect sensitive electronic equipment from voltage transients induced by load dump and other transient events, making it suitable for automotive and high-reliability applications. The device is AEC-Q101 qualified.

 

Key electrical specifications include a reverse stand-off voltage of 12V, a clamping voltage of 19.9V at a peak pulse current of 30.2A (10/1000µs waveform). The diode offers a peak forward surge current of 60A (8.3ms) and a maximum instantaneous forward voltage of 3.5V at 25A. Operating junction temperature range is -65°C to 150°C, with a power dissipation of 3W on infinite heat sink.

 

The TPSMA6L12A is housed in a low-profile DO-221AC (SMA Flat Leads) surface mount package with a height of less than 1.1mm. It is footprint compatible with standard SMA and SMB products for easy layout. The device is RoHS3 compliant and halogen free, with a moisture sensitivity level of 1 (unlimited). Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
