Product details
Overview
SZMM3Z6V2T1GX from Nexperia is a Zener voltage regulator diode in SOD323 (SC-76) package, designed for precision voltage reference and overvoltage protection in low-power circuits. It delivers a nominal 6.2 V Zener voltage with ±5 % tolerance, 0.5 Ω differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive use - deployed in power supply feedback loops and ESD-clamped sensor interfaces.
For engineers reviewing the SZMM3Z6V2T1GX datasheet, SZMM3Z6V2T1GX pinout, SZMM3Z6V2T1GX application, or SZMM3Z6V2T1GX equivalent, this page provides verified electrical characteristics, thermal performance data, cathode/anode terminal mapping, and automotive-grade reliability context essential for board-level validation and BOM selection.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation under controlled current conditions. Its 6.2 V nominal working voltage is specified at IZ = 5 mA, with temperature coefficient of +0.4 mV/K and reverse leakage <80 µA at VR = 4.7 V.
It supports non-repetitive peak reverse power dissipation up to 40 W (tp = 100 µs), while continuous total power dissipation is rated at 300 mW at Tamb = 25 °C on FR4 PCB. Junction-to-ambient thermal resistance is 415 K/W in free air.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V2,115 (Nexperia) | Same 6.2 V nominal VZ, but SOD323 package with ±2 % tolerance and 150 mW Ptot | Higher precision but lower power handling - suitable where tighter regulation outweighs surge margin | Select when design requires <±12 mV VZ tolerance and thermal budget permits reduced derating |
| MMSZ4687T1G (ON Semiconductor) | 6.2 V nominal VZ, ±5 % tolerance, 500 mW Ptot, SOD-123 package (larger footprint) | Higher continuous power but larger size - preferred where board space allows and higher steady-state dissipation needed | Choose for industrial power supplies needing >300 mW sustained dissipation with same VZ spec |
Compared with BZX384-B6V2,115, SZMM3Z6V2T1GX trades tighter tolerance for higher surge resilience and automotive qualification; versus MMSZ4687T1G, it offers smaller footprint and AEC-Q101 compliance at the cost of 200 mW lower continuous power rating.

FAQ
What is the maximum continuous reverse power dissipation for SZMM3Z6V2T1GX?
The maximum continuous total power dissipation is 300 mW at ambient temperature of 25 °C on an FR4 PCB with single-sided copper. Derating is required above 25 °C at 2.4 mW/°C based on Rth(j-a) = 415 K/W, reaching zero dissipation at 150 °C ambient.
How is polarity identified on the SZMM3Z6V2T1GX package?
Polarity is marked by a visible bar on the top surface of the SOD323 package, indicating Pin 1 (cathode). The unmarked end is Pin 2 (anode). This matches the simplified outline in Figure 11 of the datasheet and is consistent across all SZMM3Z series variants.
Does SZMM3Z6V2T1GX support reflow soldering, and what profile is recommended?
Yes, it is qualified for lead-free reflow soldering per J-STD-020. The recommended footprint uses 0.5 mm × 0.6 mm solder pads (2× each), with 0.6 mm solder resist opening. Peak temperature must not exceed 260 °C for ≤ 30 seconds, and ramp rate should be ≤ 3 °C/s.
Is the temperature coefficient of SZMM3Z6V2T1GX positive or negative, and how does it affect regulation?
The temperature coefficient is +0.4 mV/K at IZ = 5 mA, meaning output voltage increases by 0.4 mV per degree Celsius rise in junction temperature. This positive drift counteracts typical negative coefficients in lower-voltage Zeners and improves stability near 6.2 V in automotive thermal environments.
