Overview of SMBJ170A-TR by STMicroelectronics
The SMBJ170A-TR by STMicroelectronics is a Transient Voltage Suppressor (TVS) diode with a unidirectional polarity, designed to protect electronic devices by clamping high transient voltages to a safe level. The device features a peak pulse power dissipation of 600 W, a reverse standoff voltage of 170 V, and a clamping voltage of 275 V at 20.5 A, encapsulated in a plastic, ROHS compliant SMB (DO-214AA) package with 2 terminals.
This device is characterized by its breakdown voltage at a minimum of 189 V and its capability to handle a peak reverse power condition up to 4000 W momentarily. The SMBJ170A-TR operates efficiently across a broad temperature range from -55 °C to 150°C, ensuring reliability in varying environmental conditions. Moreover, this diode is built with silicon diode element material using avalanche technology, making it effective for rapid transient conditions.
The part is currently in an active lifecycle phase according to the manufacturer STMicroelectronics, highlighting its ongoing availability and support. Notably, this part is compliant with RoHS but not compliant with the REACH regulation. Its JEDEC package code is DO-214AA, and it is designed for surface mounting applications with a moisture sensitivity level of 1, indicative of its robustness in humid conditions.
