The UPT33RE3/TR7 is a 150W unidirectional transient voltage suppression (TVS) diode designed by Microchip Technology for general purpose circuit protection. It provides a reverse standoff voltage of 33V and a clamping voltage of 56.7V, with a peak pulse current rating of 2.65A. This device is intended to protect sensitive electronics from voltage transients induced by lightning, inductive load switching, and electrostatic discharge.
This TVS diode is housed in a compact DO-216AA surface mount package, also known as Powermite 1 (DO216-AA). It supports an operating temperature range of -65°C to 150°C (junction temperature), making it suitable for harsh environments. The unidirectional configuration is ideal for DC power rail and signal line protection where polarity is fixed.
The part is RoHS3 compliant and has an MSL rating of 1 (unlimited), though these compliance claims are unverified. It is designed for general purpose applications and is not intended for power line protection.
