Product details
Overview
MM3Z36VT1GX from Nexperia is a Zener voltage regulator diode in SOD323 (SC-76) package, designed for precision voltage reference and shunt regulation at 36 V nominal working voltage. It delivers ±5 % tolerance, 25.2 Ω typical differential resistance at IZ = 2 mA, 350 µA maximum reverse current at VR = 30 V, and supports up to 300 mW total power dissipation in compact PCB space-constrained applications.
For engineers reviewing the MM3Z36VT1GX datasheet, MM3Z36VT1GX pinout, MM3Z36VT1GX application, or MM3Z36VT1GX equivalent, key selection criteria include Zener voltage accuracy, low rdiff, thermal resistance (Rth(j-a) = 415 K/W), junction temperature limit (150 °C), and SOD323 footprint compatibility with high-density layouts.
Technical Context
This device operates as a two-terminal shunt regulator, maintaining stable output voltage across variable load or input conditions by conducting reverse current above its specified Zener breakdown threshold. Its 36 V nominal VZ falls within the high-voltage segment of the MM3Z series, where temperature coefficient is +0.05 mV/K and capacitance is 45 pF at 1 MHz.
The diode exhibits low dynamic impedance (25.2 Ω typ. at 2 mA) and tight voltage tolerance (±5 %), enabling accurate voltage clamping in feedback networks and overvoltage protection circuits. Thermal performance is defined for FR4 PCB mounting with single-sided copper, yielding Rth(j-sp) = 110 K/W to cathode solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 34.0 V to 38.0 V at IZ = 2 mA - defines regulated output range under standard test condition |
| Differential Resistance rdiff | 25.2 Ω typical at IZ = 2 mA - determines regulation stiffness and output voltage variation under load change |
| Reverse Current IR | 350 µA max at VR = 30 V - specifies leakage level below breakdown, critical for low-power standby operation |
| Total Power Dissipation Ptot | 300 mW at Tamb = 25 °C on FR4 PCB - sets maximum continuous DC power handling in standard layout |
| Junction Temperature Tj | −55 °C to +150 °C - defines operational and storage thermal envelope for reliability in industrial environments |
| Thermal Resistance Rth(j-a) | 415 K/W in free air - quantifies self-heating rise per watt, essential for derating in enclosed assemblies |
| Diode Capacitance Cd | 45 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and transient response in signal paths |
Pinout & Package
MM3Z36VT1GX uses the SOD323 (SC-76) surface-mount plastic package: 2.3 mm × 1.35 mm body, 0.45 mm height, cathode-marked with bar on terminal 1. Mounting requires reflow or wave soldering per Nexperia's footprint guidelines (solder land: 0.6 mm × 0.5 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct orientation during placement |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes shunt path when reverse-biased above VZ |
Key Features
| Feature | Design Value |
|---|---|
| High-Voltage Zener Range | 36 V nominal with ±5 % tolerance - enables stable reference in 24–48 V industrial power rails |
| Low Differential Resistance | 25.2 Ω typical at 2 mA - minimizes output voltage drift under varying load currents |
| Compact SMD Package | SOD323 footprint (2.3 × 1.35 mm) - saves board area in space-constrained IoT and portable designs |
| Controlled Thermal Performance | Rth(j-sp) = 110 K/W to cathode solder point - supports predictable thermal design in thermally isolated sections |
| Low Leakage at Sub-Zener Voltage | 350 µA max IR at 30 V - ensures minimal quiescent current in always-on monitoring circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B36,115 | Same 36 V nominal VZ, ±5 % tolerance, but SOD323 package with 350 mW Ptot and higher rdiff (30 Ω typ.) | Higher dynamic impedance reduces regulation precision in low-current feedback loops | Select when marginally higher power rating is needed and tighter rdiff is not critical |
| MMSZ4687T1G | 36 V nominal VZ, ±5 %, but SOD123 package (larger footprint), 500 mW Ptot, rdiff = 40 Ω typ. | Larger package increases board area use but improves thermal dissipation in high-ambient environments | Select when thermal headroom >300 mW is required and layout space permits SOD123 |
Compared with BZX384-B36,115 and MMSZ4687T1G, MM3Z36VT1GX offers the lowest differential resistance (25.2 Ω) in the smallest SOD323 footprint, making it optimal for high-precision, space-constrained shunt regulation where thermal load stays within 300 mW limits.

FAQ
What is the maximum continuous reverse current the MM3Z36VT1GX can sustain at 36 V?
The MM3Z36VT1GX is not rated for continuous reverse conduction at its Zener voltage. Its absolute maximum reverse current is limited by total power dissipation: at 36 V, sustained current must stay below 8.3 mA (300 mW ÷ 36 V) to avoid exceeding Ptot = 300 mW at Tamb = 25 °C on FR4 PCB. Derating applies above 25 °C ambient.
Does MM3Z36VT1GX have automotive qualification?
No. MM3Z36VT1GX is not AEC-Q200 qualified and is designated for industrial and commercial applications only. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or life-support systems, including automotive ECUs, unless separately validated by the customer.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At 36 V nominal, MM3Z36VT1GX has a temperature coefficient of +0.05 mV/K. Over a 165 K range (−40 °C to +125 °C), this contributes ±8.25 mV drift - negligible relative to its ±1.8 V (±5 %) initial tolerance. The dominant error source remains initial VZ tolerance, not thermal drift.
Can MM3Z36VT1GX replace a 33 V Zener in an existing design?
No direct substitution is recommended. VZ shift from 33 V to 36 V alters regulation point by 3 V, potentially violating downstream voltage margins. If redesign is possible, verify that all dependent circuits (e.g., comparator thresholds, LDO enable points) tolerate the +3 V offset and that power dissipation remains within 300 mW at the new operating point.
