1SMB5934BT3G

The 1SMB5934BT3G is a 24V Zener diode from ON Semiconductor's 1SMB59xxBT3G series of 3W plastic surface mount voltage regulator diodes. It is designed for voltage regulation and protection applications requiring a nominal zener voltage of 24V with a tolerance of ±5%.

This diode features a maximum power dissipation of 3W at a lead temperature of 75°C, with a derating factor of 40 mW/°C above 75°C. The zener impedance is 19Ω, and the forward voltage is 1.5V at 200mA. Reverse leakage current is 1µA at 18.2V. The device operates over a junction temperature range of -65°C to +150°C.

The 1SMB5934BT3G is housed in a DO-214AA (SMB) surface mount package, which provides a flat handling surface for accurate placement and supports both top-side and bottom-side board mounting. The package is molded with UL 94 V-0 flammability-rated plastic and features Pb-Free terminals. The maximum soldering temperature is 260°C for 10 seconds.

As part of the 1SMB59xxBT3G series, this diode offers an ESD rating of Class 3 (>16 kV) per the Human Body Model, enhancing robustness in electrostatic discharge environments. The device is suitable for general-purpose voltage regulation, clamping, and protection circuits in various electronic systems.
