Product details
Overview
SZMM5Z3V6T5GF from Nexperia is a Zener voltage regulator diode in SOD523 (SC-79) package, designed for precision low-voltage regulation and reference applications. It delivers a nominal 3.6 V Zener voltage at 5 mA with ±2 % tolerance, 5.0 Ω differential resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SZMM5Z3V6T5GF datasheet, SZMM5Z3V6T5GF pinout, SZMM5Z3V6T5GF application, or SZMM5Z3V6T5GF equivalent, key selection criteria include Zener voltage accuracy, low rdiff, thermal stability across −55 °C to +150 °C ambient, and suitability for space-constrained automotive sensor biasing and power rail clamping.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable output voltage by conducting reverse current above its specified breakdown threshold. Its 3.53–3.67 V Zener range at IZ = 5 mA ensures tight regulation under varying load conditions.
Thermal performance is defined by Rth(j-a) = 350 K/W (FR4 PCB, 35 mm² Cu) and Rth(j-sp) = 65 K/W, enabling reliable operation up to 150 °C junction temperature. The −3.5 mV/K temperature coefficient below 5 V supports predictable drift behavior in temperature-sensitive circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.53 V to 3.67 V at IZ = 5 mA - defines precise regulation point for low-voltage reference circuits |
| Differential Resistance (rdiff) | 5.0 Ω max - ensures minimal output voltage variation under dynamic load changes |
| Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs - enables transient overvoltage suppression without failure |
| Reverse Current (IR) | < 100 µA at VR = 1 V - guarantees low leakage in standby or high-impedance bias networks |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - supports use as forward-biased clamp or LED driver series element |
| Temperature Coefficient (SZ) | −3.5 mV/K - provides predictable negative drift for compensation in analog references |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated output node; polarity must be observed for correct Zener conduction |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C3V6 | Same 3.6 V nominal, ±5 % tolerance, SOD-523 package, but not AEC-Q101 qualified | Limited to industrial/commercial grade systems without automotive qualification requirements | Select when cost sensitivity outweighs automotive compliance needs |
| MMSZ4682T1G | 3.6 V nominal, ±5 % tolerance, SOD-123 package (larger footprint), 10 Ω rdiff | Requires more PCB area and exhibits higher regulation error under load variation | Choose only if legacy SOD-123 layout compatibility is mandatory |

FAQ
What is the maximum continuous reverse current this Zener can handle at 25 °C?
The SZMM5Z3V6T5GF has a total power dissipation limit of 300 mW at Tamb = 25 °C. At its nominal 3.6 V Zener voltage, this corresponds to a maximum continuous reverse current of approximately 83 mA (300 mW ÷ 3.6 V). Operation above this level requires thermal derating per the Rth(j-a) = 350 K/W specification.
How does the −3.5 mV/K temperature coefficient affect circuit performance?
The negative temperature coefficient means the Zener voltage decreases by 3.5 mV per Kelvin rise in junction temperature. Over a 100 °C range (25 °C to 125 °C), this results in ~350 mV total drift. Designers use this predictable behavior for temperature compensation-e.g., pairing with positive-TC components to stabilize reference outputs.
Can this device be used in forward-bias applications?
Yes-the SZMM5Z3V6T5GF has a specified forward voltage of ≤1.1 V at 100 mA, making it suitable as a low-drop series element or clamp in forward conduction. However, its primary design intent and characterization are for reverse-bias Zener operation; forward-current capability is secondary and limited to pulsed conditions per datasheet test conditions.
Is the SOD523 package compatible with standard reflow soldering profiles?
Yes-the device is qualified for lead-free reflow soldering per J-STD-020. The recommended footprint (Fig. 10) uses 0.5 mm pad width, 1.4 mm pad length, and 0.6 mm spacing. Peak temperature must not exceed 260 °C for ≤30 seconds, and thermal profile must avoid exceeding 150 °C junction temperature during ramp-up.
