Product details
Overview
MMSZ4713T1 from onsemi is a 30 V nominal Zener voltage regulator diode in SOD−123 package, rated for 500 mW power dissipation at 75°C, with 50 µA test current (IZT), 0.01 µA reverse leakage at 22.8 V, and ±5% voltage tolerance. It serves as a precision voltage reference or overvoltage clamp in low-power analog sensor interfaces and microcontroller I/O protection circuits.
For engineers reviewing the MMSZ4713T1 datasheet, pinout, applications, or equivalent options, key selection criteria include its 30 V Zener voltage, low 0.01 µA leakage at VR = 22.8 V, 500 mW FR−5 board rating, SOD−123 footprint compatibility, and AEC−Q101 qualification for automotive-grade designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation across load and line variations. Its 30 V nominal Zener voltage (VZ) is specified at IZT = 50 µA, with dynamic impedance (ZZT) optimized for low-noise reference use below 1 mA.
The device exhibits a positive temperature coefficient above ~5 V, with typical TC of +10 mV/°C near 30 V, enabling predictable thermal drift compensation in voltage reference chains. Its ESD rating exceeds 16 kV (HBM) and it supports reflow soldering up to 260°C for 10 seconds.
Key Specifications

| Power Dissipation (PD) | 500 mW @ TL = 75°C - maximum continuous power on FR−5 board before thermal derating begins |
| Reverse Leakage (IR) | 0.01 µA @ VR = 22.8 V - ensures minimal quiescent current draw in standby voltage-sense circuits |
| Junction Temp Range | −55°C to +150°C - supports operation in under-hood automotive and industrial environments |
| Package | SOD−123 (1.60 × 2.69 × 1.16 mm) - surface-mount footprint compatible with high-density PCB layouts and automated assembly |
