Product details
Overview
MM3Z10VT1GX from Nexperia is a 10 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, designed for precision voltage regulation and reference functions in low-power analog circuits.
For engineers reviewing the MM3Z10VT1GX datasheet, MM3Z10VT1GX pinout, MM3Z10VT1GX application, or MM3Z10VT1GX equivalent, key selection criteria include nominal Zener voltage (9.45–10.55 V at IZ = 5 mA), differential resistance (0.1 Ω), temperature coefficient (+4.5 to +8.0 mV/K), and thermal resistance (415 K/W junction-to-ambient).
Technical Context
This Zener diode operates in reverse breakdown with tightly controlled VZ tolerance (±5 %) and ultra-low differential resistance (0.1 Ω at IZ = 5 mA), enabling stable voltage reference performance under varying load currents. Its low capacitance (110 pF at f = 1 MHz, VR = 0 V) supports use in noise-sensitive analog signal conditioning paths.
The device features a negative-to-positive temperature coefficient transition near 5 V, and for MM3Z10VT1GX specifically, exhibits a positive TC of +4.5 to +8.0 mV/K - critical for temperature-compensated reference designs. It is qualified for operation from −55 °C to +150 °C ambient, with maximum junction temperature limited to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 9.45–10.55 V at IZ = 5 mA; ensures precise 10 V regulation within ±5 % tolerance for reference and biasing circuits |
| Differential Resistance rdiff | 0.1 Ω at IZ = 5 mA; minimizes output voltage variation under dynamic load current changes |
| Temperature Coefficient SZ | +4.5 to +8.0 mV/K at IZ = 5 mA; enables predictable drift compensation in thermally stable references |
| Total Power Dissipation Ptot | 300 mW at Tamb = 25 °C on FR4 PCB; defines continuous DC power handling in standard layout |
| Non-repetitive Peak Reverse Power | 40 W (tp = 100 µs, square wave); supports transient overvoltage clamping without damage |
| Reverse Current IR | ≤60 µA at VR = 7.0 V; guarantees low leakage in high-impedance bias networks |
| Forward Voltage VF | 1.1 V at IF = 100 mA; defines conduction loss when used in forward-biased protection or clamp roles |
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 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B10 | Same 10 V nominal, ±5 %, but higher rdiff (5 Ω) and larger SOD523 package (1.3 × 0.85 mm) | Lower regulation accuracy under load; less suitable for precision references | Select when board space permits larger footprint and cost sensitivity outweighs regulation tightness |
| MMSZ5240B | 10 V nominal, ±5 %, but higher Ptot (500 mW) and TO-236AB (SOT-23) package | Higher thermal mass supports higher continuous dissipation but requires larger PCB area | Select when >300 mW average power is needed and SOT-23 mounting is acceptable |
Compared with BZX384-B10 and MMSZ5240B, MM3Z10VT1GX offers superior regulation stability (0.1 Ω vs. 5 Ω/10 Ω rdiff) in the smallest footprint (SOD323), making it optimal for space-constrained, high-accuracy 10 V reference designs where 300 mW suffices.

FAQ
What is the maximum continuous reverse current for stable Zener operation?
The MM3Z10VT1GX is rated for continuous operation up to 30 mA at 25 °C ambient (derived from Ptot = 300 mW and VZ ≈ 10 V). At this current, junction temperature remains within safe limits on standard FR4 PCB; derating is required above 25 °C per Rth(j-a) = 415 K/W.
Does the marking 'VA' on the device correspond to MM3Z10VT1GX?
Yes - per Table 4 of the datasheet, the marking code 'VA' uniquely identifies the MM3Z10VT1GX variant within the MM3Z series, confirming its 10 V nominal Zener voltage and SOD323 package.
Can MM3Z10VT1GX be used in series for higher-voltage references?
Yes - multiple MM3Z10VT1GX diodes may be stacked in series to achieve higher reference voltages (e.g., two units yield ~20 V), but individual unit tolerances accumulate (±5 % each), and thermal coupling must be managed to avoid mismatched TC effects.
Is this device suitable for automotive applications?
No - the MM3Z10VT1GX is not AEC-Q200 qualified. While it operates from −55 °C to +150 °C, Nexperia explicitly states in Section 14 that non-automotive-qualified products are unsuitable for safety-critical or automotive use without additional customer validation and risk assumption.
