1SMB5917BT3 Description

Short technical summary and product information.

The 1SMB5917BT3 is a 4.7V Zener voltage regulator diode from On Semiconductor, designed for surface mount applications. It offers a power dissipation of 3W at a lead temperature of 75°C (zero lead length) and 550mW at 25°C ambient on an FR-4 board. The device features a maximum forward voltage of 1.5V at 200mA and a reverse leakage current of 5µA at 1.5V. With an ESD rating of Class 3 (>16kV) per the Human Body Model, it provides robust protection in demanding environments. Packaged in the industry-standard DO-214AA (SMB) case with modified L-bend leads, it is suitable for automated assembly. The operating temperature range is -65°C to 150°C. This diode is part of the 1SMB59xxBT3G series and is Pb-free and RoHS compliant (verified from datasheet).
