Product details
Overview
MM5Z5V1T5GF from Nexperia is a 5.1 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 2.0 Ω typical differential resistance at IZ = 5 mA and −2.7 to +1.2 mV/K temperature coefficient. It provides precision voltage regulation in space-constrained low-power analog and digital supply rails.
For engineers reviewing the MM5Z5V1T5GF datasheet, MM5Z5V1T5GF pinout, MM5V1T5GF application, or MM5Z5V1T5GF equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (Rth(j-sp) = 65 K/W), cathode-marked SOD523 footprint compatibility, and low-capacitance (300 pF @ 1 MHz, VR = 0 V) for noise-sensitive biasing.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load and temperature conditions. Its low 2.0 Ω differential resistance ensures minimal voltage shift across 1–10 mA Zener current range, while the −2.7 to +1.2 mV/K temperature coefficient enables predictable drift compensation in mid-voltage regulation circuits.
The device uses planar epitaxial silicon construction with metallized cathode termination, optimized for reflow soldering on FR4 PCBs with ≥35 mm² copper area at the cathode tab. Junction-to-solder-point thermal resistance of 65 K/W supports reliable operation up to 150 °C junction temperature under pulsed surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.00 V to 5.20 V at IZ = 5 mA - defines tight regulation window for 5 V rail clamping or reference generation |
| Tolerance | ±2 % - enables high-accuracy voltage setting without post-production trimming |
| Differential Resistance (rdiff) | 2.0 Ω max at IZ = 5 mA - ensures <10 mV output shift per 5 mA load change, critical for stable bias networks |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C on FR4 with 35 mm² Cu - sets continuous DC power limit for thermal design |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 µs square wave - supports transient overvoltage suppression in ESD-coupled signal lines |
| Reverse Current (IR) | ≤ 480 µA at VR = 4.5 V - guarantees low leakage in high-impedance reference divider legs |
| Diode Capacitance (Cd) | 300 pF at f = 1 MHz, VR = 0 V - limits high-frequency coupling in RF-adjacent bias circuits |
Pinout & Package
Supplied in ultra-compact SOD523 (SC-79) surface-mount plastic package (1.25 mm × 0.85 mm × 0.65 mm), featuring flat lead profile and cathode band marking for polarity identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marked by bar on package top; carries reverse-biased current during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms return path for Zener current; soldered to cathode-side copper pour for thermal conduction |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SOD523 footprint | Enables placement in 1.25 mm × 0.85 mm board area - ideal for wearables and miniaturized IoT sensor nodes |

| Low 2.0 Ω differential resistance | Maintains regulation accuracy across 1–10 mA operating range - suitable for driving op-amp input bias networks |
| 65 K/W junction-to-solder-point Rth | Allows direct thermal coupling to PCB copper, enabling >100 mW sustained dissipation without heatsinking |
| 300 pF capacitance at 0 V | Minimizes signal distortion in high-speed comparator reference inputs and ADC voltage dividers |
Applications
| Power Supply Rail Clamping | Low-Power Reference Generation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C5V1 | Same 5.1 V nominal, ±5 % tolerance, SOD523 package, but higher rdiff (10 Ω) and lower PZSM (25 W) | Acceptable for non-critical biasing where ±5 % voltage error is tolerable | Select when cost sensitivity outweighs regulation precision and surge robustness |
| MM3Z5V1T1G | Same 5.1 V, ±2 %, but in larger SOD323 (SC-76) package (1.7 mm × 1.3 mm); identical rdiff and PZSM | Preferred where manual rework or thermal margin >350 mW is required | Select when board layout allows larger footprint and higher continuous power is needed |
Compared with BZX584-C5V1 and MM3Z5V1T1G, MM5Z5V1T5GF delivers tighter voltage control and superior surge handling in the smallest possible footprint-making it optimal for high-density, low-power regulation where space and precision are constrained.

FAQ
What is the maximum continuous Zener current for MM5Z5V1T5GF at 70 °C ambient?
At Tamb = 70 °C, derated power dissipation is 210 mW (based on 300 mW @ 25 °C and Rth(j-a) = 350 K/W). With VZ ≈ 5.1 V, maximum continuous IZ is 41 mA. Exceeding this risks thermal runaway due to positive temperature coefficient above 5 V.
Can MM5Z5V1T5GF be used in place of a 5.0 V Zener in an existing design?
Yes, with verification of tolerance impact: MM5Z5V1T5GF's 5.00–5.20 V range falls within typical 5.0 V ±5 % designs. Its lower rdiff (2.0 Ω vs. 5–10 Ω for older parts) improves load regulation, but forward voltage (1.1 V @ 100 mA) must be checked if used in series configurations.
How does the cathode band orientation affect PCB layout for MM5Z5V1T5GF?
The marking bar on the SOD523 package identifies Pin 1 (cathode). Correct orientation ensures reverse bias during operation: cathode must connect to higher potential (e.g., 5 V rail), anode to lower potential (e.g., ground). Misorientation causes forward conduction and loss of regulation.
Is MM5Z5V1T5GF suitable for automotive applications?
No. This device is not AEC-Q200 qualified and lacks automotive-grade screening, temperature validation beyond 150 °C junction, or guaranteed PPAP documentation. For automotive use, specify Nexperia's automotive-qualified equivalents such as PZM5.1B or BZX84-C5V1E.
