SZMM5Z4686T1G Description

Short technical summary and product information.

The SZMM5Z4686T1G is a surface mount Zener diode from On Semiconductor (onsemi). It features a nominal Zener voltage of 3.9V with a tolerance of ±5.13%, making it suitable for voltage regulation and clamping applications. The device is rated for a power dissipation of 500mW, allowing it to handle moderate power levels in a compact SOD-523 package.

Electrical characteristics include a forward voltage of 900 mV typical at 10 mA, and a reverse leakage current of 5 µA typical at 2V. The operating junction temperature range spans from -55°C to 150°C, enabling use in a wide variety of environments.

The diode is designed for surface mount assembly and is supplied in the SOD-523 (SC-79) package. This small footprint makes it ideal for space-constrained designs. The part is listed as RoHS3 compliant and REACH unaffected, though these compliance claims are unverified. Moisture sensitivity level is rated as 1 (unlimited).

Applications include voltage reference, overvoltage protection, and general purpose Zener regulation in consumer, industrial, and automotive electronics where a 3.9V reference is needed.
