Product details
Overview
MM3Z11VT1GX from Nexperia is a 11 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 0.1 Ω typical differential resistance at IZ = 8 mA and temperature coefficient of +5.4 mV/K - used for precision voltage reference and low-power regulation in sensor biasing and analog front-end circuits.
For engineers reviewing the MM3Z11VT1GX datasheet, MM3Z11VT1GX pinout, MM3Z11VT1GX application, or MM3Z11VT1GX equivalent, this page delivers verified electrical characteristics, thermal behavior, cathode/anode terminal mapping, and real-world use cases in industrial signal conditioning and portable power management designs.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 11 V at IZ = 8 mA, exhibiting low dynamic impedance (0.1 Ω max) and tight voltage tolerance (±5 %). Its junction temperature range spans −55 °C to +150 °C, and it maintains stable regulation under transient surges up to 40 W (100 µs square wave).
Thermal resistance from junction to ambient is 415 K/W on standard FR4 PCB, while junction-to-solder-point resistance is 110 K/W - enabling reliable operation in space-constrained, thermally unmanaged layouts. Reverse current remains ≤60 µA at VR = 9.45 V (10.55 V min/max VZ envelope).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Nominal) | 11 V at IZ = 8 mA - defines stable regulation point for reference circuits |
| Tolerance | ±5 % - ensures predictable voltage accuracy across production lots |
| rdiff | 0.1 Ω max at IZ = 8 mA - minimizes output voltage shift under load variation |
| Ptot | 300 mW at Tamb = 25 °C - sets maximum continuous DC power handling on standard PCB |
| PZSM | 40 W (100 µs square wave) - supports ESD/transient suppression in low-energy surge paths |
| SZ | +5.4 mV/K - positive temperature coefficient enables compensation in multi-diode references |
| Cd | 108 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and stability in feedback loops |

Applications
| Industrial Sensor Biasing | Portable Device Voltage Reference |
|---|---|
Use Scenario: Providing stable excitation voltage to resistive temperature detectors (RTDs) in factory-floor transmitters. IC Role / Device Role / Timing Role: Zener diode acts as two-terminal shunt voltage reference, replacing bulkier IC references where 1% accuracy suffices. Use Value: Delivers 11 V ±0.55 V regulation with <0.1 Ω dynamic impedance, minimizing self-heating error and enabling direct connection to 12-bit ADC input stages. |
Use Scenario: Generating precise 11 V reference for lithium-ion battery fuel gauging ICs in handheld medical monitors. IC Role / Device Role / Timing Role: Functions as low-quiescent-current voltage clamp in analog front-end power domain. Use Value: Draws only 8 mA operating current and maintains <60 µA leakage at 9.45 V, extending battery runtime while ensuring ADC reference stability across −20 °C to +70 °C. |
| Low-Power Analog Signal Conditioning | ESD-Sensitive Interface Protection |
Use Scenario: Biasing op-amp input stages in 4–20 mA loop-powered transmitters with limited PCB real estate. IC Role / Device Role / Timing Role: Provides rail-stabilized reference for instrumentation amplifier common-mode setting. Use Value: SOD323 package fits within 2.7 mm × 1.6 mm footprint; 300 mW rating supports continuous operation without heatsinking in sealed enclosures. |
Use Scenario: Secondary-level clamping on RS-485 receiver inputs subjected to IEC 61000-4-2 contact discharge. IC Role / Device Role / Timing Role: Shunt limiter absorbing sub-100 ns transients before they reach IC protection diodes. Use Value: Withstands 40 W surge (100 µs) and exhibits 108 pF capacitance - low enough to avoid signal integrity degradation at 250 kbps data rates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B11 | Same 11 V nominal, ±5 %, but SOD323 package with 200 mW Ptot rating | Limited to lower continuous power; unsuitable for sustained 8 mA biasing above 60 °C ambient | Select when thermal budget is constrained and peak surge immunity is secondary |
| MMSZ4689 | 11 V, ±5 %, SOD123 package, 500 mW Ptot, rdiff = 0.25 Ω | Larger footprint (3.7 mm × 1.6 mm); higher power but poorer regulation stiffness | Choose for higher continuous power needs where board area permits larger package |
Compared with BZX384-B11, MM3Z11VT1GX offers +100 mW power margin and tighter dynamic impedance; versus MMSZ4689, it trades 200 mW headroom for 2.5× smaller footprint and superior regulation linearity - making it optimal for miniaturized, thermally isolated analog nodes.

FAQ
What is the maximum continuous forward current for MM3Z11VT1GX?
The MM3Z11VT1GX is not rated for continuous forward conduction; its primary function is reverse-bias Zener operation. Forward voltage is specified at 1.1 V max for 100 mA pulsed test (tp ≤ 300 µs), and absolute maximum forward current is 200 mA per limiting values table - but sustained forward bias risks thermal runaway and is outside intended use.
Can MM3Z11VT1GX be used as a substitute for a 10 V Zener in an existing design?
No - MM3Z11VT1GX has a nominal Zener voltage of 11 V (10.44–11.56 V range), not 10 V. Substituting it for a 10 V part would shift regulation by ~1 V, potentially violating downstream IC input voltage limits or altering bias points in analog circuits; use MM3Z10VT1G for 10 V applications.
How does the +5.4 mV/K temperature coefficient affect long-term stability?
The +5.4 mV/K coefficient means VZ increases by 5.4 mV per 1 °C rise in junction temperature. Over a 100 °C range (−25 °C to +75 °C), this causes ~540 mV drift - acceptable in non-critical references but requires compensation (e.g., complementary diodes or resistor networks) in precision metrology applications.
Is MM3Z11VT1GX suitable for automotive applications?
No - MM3Z11VT1GX is not AEC-Q200 qualified. Nexperia explicitly states in its legal disclaimers that non-automotive-qualified products like the MM3Z series are unsuitable for safety-critical or life-support systems; automotive designs require parts explicitly tested to AEC-Q200 with full PPAP documentation.
