1SMA5938BT3G Description

Short technical summary and product information.

The 1SMA5938BT3G is a 1.5 Watt surface-mount Zener voltage regulator diode from On Semiconductor, part of the 1SMA59xxBT3G series. It provides a nominal Zener voltage of 36V with ±5% tolerance, suitable for voltage regulation and protection circuits.

 

Key electrical specifications include a maximum impedance (Zzt) of 38Ω, reverse leakage current of 500nA at 27.4V, and a forward voltage drop of 1.2V at 200mA. The device features an ESD rating of Class 3 (>16 kV) per Human Body Model, ensuring robust handling during assembly.

 

Thermal characteristics: the diode can dissipate up to 1.5W at a lead temperature of 75°C (derating 20mW/°C), with a derated 0.5W at 25°C ambient. Operating junction temperature ranges from -65°C to +150°C, with a junction-to-ambient thermal resistance of 250°C/W. The device is packaged in a DO-214AC (SMA) surface-mount case, with cathode indicated by a molded notch or band. It is Pb-Free and rated UL 94 V-0 flammability.
