SMM4F33A-TR Description

Short technical summary and product information.

The STMicroelectronics SMM4F33A-TR is a unidirectional transient voltage suppression (TVS) diode designed for general purpose circuit protection. It features a Zener-type clamping diode structure and provides protection against voltage transients. The device has a reverse standoff voltage of 33V and a maximum clamping voltage of 69.7V at 33A peak pulse current (8/20µs waveform). It is rated for 400W peak pulse power. The SMM4F33A-TR is housed in a surface mount DO-222AA package (also designated DO222-AA) and supports an operating temperature range from -55°C to 175°C. It is suitable for use in a variety of applications requiring voltage clamping protection. The device is available in tape and reel packaging for automated assembly. It is RoHS3 compliant, REACH unaffected, and has an MSL rating of 1.
