TPSMA6L43A Description

Short technical summary and product information.

The TPSMA6L43A is a 600W peak pulse power unidirectional TVS diode from Littelfuse Inc., part of the TPSMA6L series. It is designed to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events. This device is especially suitable for high reliability and automotive applications.

 

Key electrical specifications include a reverse standoff voltage of 43 V, a maximum clamping voltage of 69.4 V at 8.7 A peak pulse current, and a peak pulse current rating of 8.7 A under a 10/1000 µs waveform. The diode also features a maximum forward voltage of 3.5 V at 25 A and a peak forward surge current of 60 A. It operates over a junction temperature range of -65°C to 150°C.

 

The TPSMA6L43A is housed in a surface mount DO-221AC (SMA low profile) package, which offers the same electrical performance as the SMB package but with a lower height profile of 1.1 mm. It is AEC-Q101 qualified for automotive applications and provides ESD protection of 30 kV (air) and 30 kV (contact) per IEC 61000-4-2. The device is RoHS3 compliant, halogen free, and lead free.

 

Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The unidirectional polarity makes it suitable for DC line protection where only one polarity needs to be clamped.
