Product details
Overview
MM5Z4V7T5GF from Nexperia is a Zener voltage regulator diode in SOD523 (SC-79) package, designed for precision low-voltage regulation and reference applications. It delivers a nominal 4.7 V Zener voltage at 5 mA with ±2 % tolerance, 3.0 Ω differential resistance, and operates within −55 °C to +150 °C ambient range - used in power supply feedback loops, voltage clamping, and analog reference circuits.
For engineers reviewing the MM5Z4V7T5GF datasheet, MM5Z4V7T5GF pinout, MM5Z4V7T5GF application, or MM5Z4V7T5GF equivalent, this page provides verified electrical characteristics, thermal behavior, cathode/anode terminal mapping, and real-world use context for compact board-level voltage stabilization.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage under varying load and input conditions. Its 4.7 V nominal Zener voltage is specified at IZ = 5 mA, with low 3.0 Ω dynamic resistance ensuring minimal voltage deviation across current changes.
Thermal resistance from junction to solder point is 65 K/W, enabling reliable operation on FR4 PCBs with ~35 mm² copper area at the cathode tab. The device supports non-repetitive surge power up to 40 W (100 µs square wave), making it suitable for transient overvoltage suppression in low-energy circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 4.61 V to 4.79 V at IZ = 5 mA - ensures tight 4.7 V regulation for feedback and reference accuracy |
| Differential Resistance rdiff | 3.0 Ω max - minimizes output voltage shift under load current variation |
| Reverse Current IR | ≤ 2.0 µA at VR = 3.0 V - guarantees low leakage in standby or high-impedance bias networks |
| Total Power Dissipation Ptot | 300 mW at Tamb = 25 °C - defines continuous DC power handling on standard PCB layout |
| Non-repetitive Peak Power PZSM | 40 W (100 µs square wave) - enables short-duration surge clamping without damage |
| Forward Voltage VF | 1.1 V max at IF = 100 mA - confirms low-loss forward conduction during polarity-reversal protection |
| Temperature Coefficient SZ | −3.5 mV/K to +0.2 mV/K - quantifies Zener voltage drift over temperature for stability-critical references |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C4V7 | Same 4.7 V nominal, ±5 % tolerance, SOD-523 package, but higher 10 Ω rdiff | Lower regulation precision; acceptable where ±5 % output tolerance is sufficient | Select for cost-sensitive designs where tighter voltage stability is not required |
| MM3Z4V7T1G | Same 4.7 V nominal, ±2 % tolerance, but SOD-323 package (1.7 mm × 1.3 mm) and 5.0 Ω rdiff | Larger footprint and higher dynamic resistance reduce regulation accuracy in high-precision feedback | Choose only if SOD-323 is already standardized in existing layout and thermal margin permits |
Compared with BZX584-C4V7 and MM3Z4V7T1G, MM5Z4V7T5GF offers superior regulation accuracy (±2 % vs. ±5 %), lower dynamic resistance (3.0 Ω vs. 10 Ω / 5.0 Ω), and optimized thermal performance (65 K/W junction-to-solder-point) - critical for compact, high-stability reference designs.

FAQ
What is the maximum continuous reverse current the MM5Z4V7T5GF can sustain without exceeding its 300 mW power limit?
At 4.7 V Zener voltage, the absolute maximum continuous reverse current is 63.8 mA (Ptot/VZ = 0.3 W / 4.7 V). However, derating is required above 25 °C ambient per the 350 K/W junction-to-ambient thermal resistance - actual usable current drops to ~45 mA at 60 °C ambient to maintain Tj ≤ 150 °C.
How does the cathode marking on the MM5Z4V7T5GF align with the SOD523 package outline?
The cathode is marked by a visible bar on the top surface of the SOD523 package, positioned adjacent to Pin 1 as defined in Nexperia's package drawing (Fig. 9). This matches the simplified outline showing Pin 1 labeled "K" (cathode) and Pin 2 labeled "A" (anode), with the bar aligned parallel to the long edge nearest Pin 1.
Can the MM5Z4V7T5GF be used in place of a 5.1 V Zener for undervoltage lockout (UVLO) in a 3.3 V system?
No - its 4.7 V nominal Zener voltage is outside the typical UVLO threshold window for 3.3 V systems (usually 2.7–3.0 V). Using it would cause premature shutdown; a dedicated 2.7 V or 3.0 V Zener (e.g., MM5Z2V7T5G or MM5Z3V0T5G) is required to match standard UVLO hysteresis bands.
Is the MM5Z4V7T5GF rated for automotive applications per AEC-Q200?
No - the MM5Z4V7T5GF is not AEC-Q200 qualified. Nexperia's official documentation states that unless explicitly designated as automotive-qualified, products like the MM5Z series are intended for industrial and consumer use only. Automotive deployment requires verification of qualification status via Nexperia's automotive product portal or direct consultation with their sales team.
