SZMMSZ5239BT1G Description

Short technical summary and product information.

The SZMMSZ5239BT1G is a 9.1V Zener diode from the SZMMSZ52xxxT1G series manufactured by On Semiconductor (onsemi). It is designed for voltage regulation applications in surface mount assemblies.

 

Key electrical specifications include a nominal Zener voltage of 9.1V with ±5% tolerance, maximum power dissipation of 500mW, and a maximum impedance of 10Ω. The device features a low reverse leakage current of 3µA at 7V and a forward voltage of 900mV at 10mA.

 

Packaged in a SOD-123 case, this diode supports surface mount mounting and operates over a junction temperature range of -55°C to +150°C. The SZ prefix indicates automotive qualification, meeting AEC-Q101 requirements and PPAP capability. The device also offers an ESD rating of Class 3 (>16kV) per the Human Body Model.

 

This Zener diode is suitable for voltage regulation, clamping, and protection circuits in automotive, industrial, and consumer electronics. The lead-free finish and RoHS3 compliance ensure environmental compatibility.
