The SZ1SMB5915BT3G is a 3.9V Zener diode from onsemi's 1SMB59xxBT3G series, designed for voltage regulation in surface mount applications. It offers a nominal Zener voltage of 3.9V with ±5% tolerance and a maximum power dissipation of 3W at lead temperature 75°C (550mW at ambient 25°C). The device features a low maximum impedance of 7.5Ω at the test current IZT, ensuring stable regulation.
This Zener diode is housed in a DO-214AA (SMB) package, suitable for automated assembly. It has an ESD rating of Class 3 (>16kV) per Human Body Model, providing robust protection. The operating temperature range spans -65°C to 150°C, making it suitable for harsh environments. The device is Pb-free and RoHS compliant, with UL 94 V-0 flammability rating.
Typical applications include voltage clamping, overvoltage protection, and reference voltage generation in power supplies, automotive electronics, and industrial equipment. The SMB package allows for efficient heat dissipation through the leads, with a junction-to-lead thermal resistance of 25°C/W.
