Product details
Overview
MM5Z11VT5GF from Nexperia is a 11 V ±2 % tolerance Zener diode in SOD523 (SC-79) 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 5.4 mV/K temperature coefficient - used for precision voltage reference and low-power regulation in space-constrained consumer and industrial PCBs.
For engineers reviewing the MM5Z11VT5GF datasheet, MM5Z11VT5GF pinout, MM5Z11VT5GF application, or MM5Z11VT5GF equivalent, this page delivers verified Zener parameters, cathode/anode terminal mapping, thermal resistance (65 K/W to solder point), and real-world regulation use cases - supporting rapid BOM validation and layout integration.
Technical Context
This Zener operates in reverse breakdown mode with nominal VZ = 11.0 V (min 10.78 V, max 11.22 V at IZ = 8 mA), delivering stable regulation under low-current conditions (IZ ≥ 1 mA). Its low rdiff (0.1 Ω) ensures minimal output voltage drift across load variations.
Thermal performance is defined by Rth(j-sp) = 65 K/W to solder point and Rth(j-a) = 350 K/W in free air, requiring minimal copper area (35 mm² at cathode tab) for safe 300 mW operation. The −55 °C to +150 °C ambient range supports industrial-grade deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 11.0 V - precise regulation setpoint for biasing, reference, or overvoltage clamping |
| Tolerance | ±2 % - tight VZ spread enables consistent circuit behavior without post-production trimming |
| rdiff | 0.1 Ω - low dynamic impedance minimizes output voltage variation under changing load current |
| SZ | +5.4 mV/K - positive temperature coefficient allows predictable VZ drift up to +150 °C junction |
| Ptot | 300 mW - maximum continuous power dissipation on FR4 PCB with 35 mm² cathode copper |
| PZSM | 40 W - surge rating for transient suppression (100 µs square wave, Tj = 25 °C pre-surge) |
| Cd | 110 pF @ 1 MHz, VR = 0 V - low capacitance preserves high-frequency signal integrity in filtering paths |
Pinout & Package
SOD523 (SC-79) ultra-small surface-mount plastic package: 1.25 mm × 0.85 mm footprint, 0.65 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener conduction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C11 | Same 11 V nominal, ±5 % tolerance, SOD523 package, but higher rdiff (1.0 Ω) and lower PZSM (25 W) | Less stable under dynamic load; unsuitable for precision references but adequate for basic clamping | Select when cost sensitivity outweighs regulation accuracy and surge robustness |
| MM3Z11VT1G | Same 11 V, ±2 %, but SOD323 package (larger footprint), 200 mW Ptot, and higher rdiff (0.2 Ω) | Lower power handling and reduced thermal performance limit use in sustained 8 mA+ applications | Choose only if SOD323 footprint compatibility is required and 300 mW derating is acceptable |
Compared with BZX584-C11 and MM3Z11VT1G, MM5Z11VT5GF delivers superior regulation precision (±2 % vs ±5 %), lower impedance (0.1 Ω vs 1.0/0.2 Ω), and higher surge resilience (40 W vs 25 W / not specified), making it optimal for space-constrained, high-stability designs.

FAQ
What is the maximum continuous forward current for MM5Z11VT5GF?
The MM5Z11VT5GF is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 200 mA per limiting values table, but forward conduction is not its functional mode. In normal use, forward voltage remains below 1.1 V at 100 mA, and forward operation should be avoided in regulation circuits.
Can MM5Z11VT5GF replace a 12 V Zener in an existing design?
No - MM5Z11VT5GF has a nominal Zener voltage of 11.0 V (10.78–11.22 V), not 12 V. Substituting it for a 12 V part would reduce regulated output by ~1 V, potentially causing undervoltage faults in downstream circuitry. Use MM5Z12VT5G for 12 V applications.
How does the SOD523 package affect thermal performance?
The SOD523 package limits thermal dissipation: Rth(j-sp) is 65 K/W to the cathode solder point, but Rth(j-a) rises to 350 K/W in free air. To sustain 300 mW, the cathode pad must connect to ≥35 mm² of 1 oz copper; insufficient copper causes junction temperatures to exceed 150 °C.
Is MM5Z11VT5GF suitable for automotive applications?
No - this device is not AEC-Q200 qualified. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products like MM5Z11VT5GF are not tested or warranted for automotive use. For automotive systems, select AEC-Q200-compliant Zeners such as PZU11B2 or BZX84-C11E.
