The 1SMB5929BT3G is a 15V Zener diode from On Semiconductor's 1SMB59xxBT3G series, designed for voltage regulation in surface mount applications. It offers a power dissipation of 3W at a lead temperature of 75°C and 550mW at 25°C ambient, with derating above those temperatures. The device features a low Zener impedance of 9Ω and a reverse leakage current of 1µA at 11.4V.
This Zener diode is housed in a void-free, transfer-molded plastic DO-214AA (SMB) package with a modified L-bend lead design for improved contact area. It is rated for an operating temperature range of -65°C to 150°C and has an ESD rating of Class 3 (>16 kV) per the Human Body Model. The package is rated UL 94 V-0 for flammability.
Typical applications include overvoltage protection, voltage clamping, and reference voltage generation in power supplies, industrial controls, and consumer electronics. The device is Pb-Free and designed for reliable performance in demanding environments.
The Zener voltage is 15 V.
The device can dissipate 3 W at a lead temperature of 75°C and 550 mW at 25°C ambient.
The device is available in a DO-214AA (SMB) surface mount package.
The operating temperature range is -65°C to 150°C.
The datasheet states the device is Pb-Free, but RoHS compliance is unverified.
The device has an ESD rating of Class 3 (>16 kV) per the Human Body Model.
The Zener voltage tolerance is ±5%.
