TPSMA6L11A Description

Short technical summary and product information.

The TPSMA6L11A is a 600W unidirectional TVS diode designed for protecting sensitive electronic circuits from voltage transients. It features a reverse standoff voltage of 11V, a minimum breakdown voltage of 12.2V, and a maximum clamping voltage of 18.2V at 33A peak pulse current (10/1000µs waveform). The device delivers 600W peak pulse power dissipation and includes built-in ESD protection of 30kV air and 30kV contact per IEC 61000-4-2 with a typical response time under 1.0ns.

 

This TVS diode is automotive AEC-Q101 qualified and suitable for high-reliability applications such as load dump protection in automotive electronics, as well as I/O interface and VCC bus protection in telecom, industrial, and consumer systems. It maintains performance over an operating temperature range of -50°C to 150°C and provides a typical thermal resistance of 35°C/W junction-to-lead.

 

The TPSMA6L11A is offered in a low-profile DO-221AC (SMA Flat Leads) surface-mount package with a height under 1.1mm, making it compatible with standard SMA and SMB footprints. The device is halogen free, lead-free (Pb-free E3), and RoHS3 compliant as verified by the datasheet.
