MM5Z4689T1G Description

Short technical summary and product information.

The onsemi MM5Z4689T1G is a Zener voltage regulator diode offering a nominal Zener voltage of 5.1V with ±5% tolerance. It is rated for maximum power dissipation of 500mW on FR-5 board at 75°C lead temperature. The device features low reverse leakage current of 10µA at 3V reverse voltage and a maximum forward voltage of 900mV at 10mA.

Designed for space-constrained applications, the MM5Z4689T1G is packaged in a SOD-523 surface mount case. It supports an operating junction temperature range of -55°C to 150°C and has a junction-to-ambient thermal resistance of 250°C/W. The component is ESD rated Class 3 (>16kV HBM) and the molding compound is UL 94 V-0 flammability rated.

This Zener diode is suitable for voltage regulation, protection, and reference circuits in portable electronics such as cellular phones, handheld devices, and high-density PC boards. It is supplied in tape and reel packaging with a standard quantity of 3000 pieces per reel.
