The 1SMB5939B-13 is a 39V Zener diode from Diodes Incorporated, part of the 1SMB59xxB series of 3.0W surface mount power Zener diodes. It provides a nominal Zener voltage of 39V with a tolerance of ±5%, making it suitable for voltage regulation and clamping applications. The device is rated for a maximum power dissipation of 3W at a lead temperature of 75°C, and 550mW at ambient temperature of 25°C. It features a maximum forward voltage of 1.5V at 200mA and a reverse leakage current of 1µA at 29.7V. The Zener impedance (Zzt) is 45Ω maximum.
The diode is housed in a DO-214AA (SMB) surface mount package, which is ideal for automated assembly. It has an ESD rating of >16kV per Human Body Model, ensuring robustness in handling. The operating temperature range is -65°C to 150°C. The device is RoHS3 compliant, halogen and antimony free, and has a moisture sensitivity level of 1 (unlimited). It is supplied in tape and reel packaging with 3000 units per reel.
Typical applications include voltage regulation, overvoltage protection, and reference voltage generation in power supplies and other electronic circuits. The SMB package allows for compact design and efficient heat dissipation.
