MMSZ47T1G

MMSZ47T1G Description

The MMSZ47T1G from onsemi is a high-performance 47V Zener diode designed for precision voltage regulation and protection in compact surface-mount applications. Packaged in a SOD-123 form factor, it delivers a robust 500 mW power dissipation with a tight ±5% tolerance on the nominal Zener voltage (Vz). Its low reverse leakage current of 50 nA @ 32.9 V ensures minimal power loss, while the forward voltage (Vf) remains below 900 mV @ 10 mA, enhancing efficiency in bidirectional circuits. Compliant with ROHS3 and REACH standards, this diode is ideal for modern electronics requiring environmental compliance.
