Product details
Overview
MM3Z3V6T1GX from Nexperia is a 3.6 V ±5 % tolerance Zener diode in SOD323 (SC-76) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, with 90 Ω typical differential resistance at IZ = 5 mA and −3.5 to 0 mV/K temperature coefficient - used for precision low-voltage reference and voltage regulation in space-constrained power rails.
For engineers reviewing the MM3Z3V6T1GX datasheet, MM3Z3V6T1GX pinout, MM3Z3V6T1GX application, or MM3Z3V6T1GX equivalent, this page delivers verified electrical characteristics, thermal behavior, cathode/anode terminal mapping, and real-world use cases in analog sensing, LDO feedback, and microcontroller reset circuitry.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 3.4–3.8 V regulation across 0.5–5 mA test currents, with low dynamic impedance enabling tight voltage control under varying load conditions. Its junction-to-ambient thermal resistance of 415 K/W (FR4 PCB, single-sided copper) defines thermal derating limits above 25 °C ambient.
The device exhibits a negative temperature coefficient (−3.5 to 0 mV/K), meaning output voltage decreases slightly with rising temperature - critical for biasing circuits requiring predictable drift compensation. Reverse leakage remains ≤1000 µA at 2.7 V, ensuring minimal quiescent current in standby modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4 V to 3.8 V at IZ = 5 mA - defines regulated output range for low-voltage reference design |
| Tolerance | ±5 % - ensures predictable voltage accuracy without post-production trimming |
| Differential Resistance (rdiff) | 5.0 Ω max at IZ = 5 mA - enables stable regulation under small-signal load transients |
| Total 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 square wave - supports transient overvoltage clamping in ESD protection paths |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - confirms low-loss conduction when used in series forward-biased configurations |
| Junction Temperature (Tj) | 150 °C max - determines maximum allowable operating temperature before permanent degradation |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, ultra-compact footprint (2.7 × 1.6 mm), cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low differential resistance | 5.0 Ω max at 5 mA - minimizes output voltage shift under load variation |
| Wide working voltage range | 2.4 V to 75 V coverage across MM3Z series - supports scalable reference design across multiple rail voltages |
| Small-outline packaging | SOD323 (SC-76) - enables high-density placement in portable and wearables PCB layouts |
| Controlled temperature coefficient | −3.5 to 0 mV/K - allows predictable drift modeling in temperature-sensitive analog stages |
| Low reverse leakage | ≤1000 µA at VR = 2.7 V - reduces standby current in battery-powered regulation nodes |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V6,115 (Nexperia) | Same 3.6 V nominal, ±5 % tolerance, but in larger SOD323 variant with 500 mW Ptot | Higher power handling supports sustained 10 mA regulation; less suitable for ultra-low-power designs | Select when >300 mW continuous dissipation is required and board space permits identical footprint |
| MMBZ5226BS-7-F (Diodes Inc.) | 3.6 V, ±5 %, but in SOT-323 package with 200 mW Ptot and 15 Ω rdiff | Higher dynamic impedance degrades regulation under load change; lower power rating limits headroom | Choose only if legacy SOT-323 compatibility is mandatory and 5 Ω rdiff is not required |
Compared with BZX384-B3V6 and MMBZ5226BS-7-F, MM3Z3V6T1GX offers optimal balance of low impedance (5 Ω), compact size (SOD323), and 300 mW power - making it preferred for modern low-power, high-density regulation where voltage stability under dynamic load is critical.

FAQ
What is the maximum continuous reverse current this Zener can handle at 25 °C?
The MM3Z3V6T1GX supports up to 5 mA test current for Zener voltage specification, but its absolute maximum forward current is 200 mA. Continuous reverse current must be limited by external series resistance to ensure power dissipation stays within 300 mW - at 3.6 V, this corresponds to ~83 mA maximum average reverse current at 25 °C ambient on standard FR4 PCB.
Can this diode be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing variations in breakdown voltage, causing current imbalance when paralleled. Even with matched units, thermal runaway risk exists due to negative temperature coefficient. For higher power, use a single higher-rated Zener or switch to an active shunt regulator topology.
How does the marking 'XZ' correspond to MM3Z3V6T1GX?
Per Nexperia's marking table, 'XZ' is the top-side laser marking code for MM3Z3V6T1GX. The bar adjacent to pin 1 identifies the cathode terminal, and 'XZ' uniquely distinguishes this 3.6 V variant within the MM3Z series on the physical device.
Is this part suitable for automotive applications?
No - MM3Z3V6T1GX is not AEC-Q200 qualified and lacks automotive-grade screening, temperature validation, or failure rate data. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use only in commercial or industrial applications unless independently validated per automotive requirements.
