Product details
Overview
MM5Z3V6T5GF 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 Zener voltage of 3.6 V with ±2 % tolerance, 5.0 Ω differential resistance at IZ = 5 mA, and supports up to 300 mW total power dissipation at Tamb = 25 °C on FR4 PCB with 35 mm² copper area - used in voltage clamping, overvoltage protection, and analog reference circuits.
For engineers reviewing the MM5Z3V6T5GF datasheet, MM5Z3V6T5GF pinout, MM5Z3V6T5GF application, or MM5Z3V6T5GF equivalent, key selection criteria include its 3.53–3.67 V working voltage range, low 5.0 Ω dynamic impedance, cathode-marked SOD523 footprint, and suitability for space-constrained consumer and industrial power management designs.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable voltage across load variations, with specified test conditions at Tj = 25 °C and IZ = 5 mA. Its temperature coefficient is −3.5 to 0 mV/K, enabling predictable drift behavior in ambient ranges from −55 °C to +150 °C.
The device features non-repetitive peak reverse power dissipation of 40 W (tp = 100 µs, square wave), forward voltage ≤1.1 V at IF = 100 mA, and junction-to-ambient thermal resistance of 350 K/W under standard mounting - confirming its role as a compact, transient-tolerant voltage clamp.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.53 V to 3.67 V at IZ = 5 mA - defines precise regulation window for 3.3 V system rail stabilization |
| Differential Resistance (rdiff) | 5.0 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load current shifts |
| Power Dissipation (Ptot) | 300 mW max at Tamb = 25 °C on FR4 with 35 mm² Cu - sets continuous DC power handling limit |
| Reverse Current (IR) | ≤90 µA max at VR = 1 V - confirms low leakage in standby or pre-breakdown state |
| Forward Voltage (VF) | ≤1.1 V at IF = 100 mA - enables use as low-drop rectifier or ESD path in bidirectional protection |
| Thermal Resistance (Rth(j-a)) | 350 K/W - determines junction temperature rise per watt in free-air PCB mount |
| Capacitance (Cd) | 390 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and signal integrity in RF-adjacent layouts |
Pinout & Package
MM5Z3V6T5GF uses the SOD523 (SC-79) ultra-small surface-mount plastic package: 1.25 mm × 0.85 mm × 0.65 mm body, 0.34 mm lead pitch, cathode identified by marking bar on terminal 1.
| 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; completes reverse-bias path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables tight regulation without post-production trimming in cost-sensitive consumer power rails |
| 5.0 Ω typical differential resistance | Minimizes load-induced voltage deviation in feedback networks for LDOs or ADC references |
| SOD523 ultra-compact footprint | Supports high-density layout in wearables, IoT sensors, and portable battery-powered devices |
| −55 °C to +150 °C operating range | Validates reliability in automotive cabin modules and industrial control enclosures without derating |
| 40 W non-repetitive surge rating | Provides transient immunity against ESD events per IEC 61000-4-2 Level 4 (±15 kV air) when properly decoupled |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C3V6 | Same 3.6 V nominal, ±5 % tolerance, SOD523 package, but higher rdiff = 90 Ω | Less stable under varying load; suitable only for non-critical biasing | Select when cost priority outweighs regulation precision and thermal performance |
| MMSZ4685-TP | 3.6 V nominal, ±5 %, SOD123 package (larger), rdiff = 15 Ω, Ptot = 500 mW | Higher power handling but 2× footprint; incompatible with ultra-dense layouts | Choose when board space allows and >300 mW continuous dissipation is required |
Compared with BZX584-C3V6 and MMSZ4685-TP, MM5Z3V6T5GF offers superior voltage accuracy (±2 % vs ±5 %), lower dynamic impedance (5.0 Ω vs 15–90 Ω), and smallest possible SOD523 footprint - making it optimal for precision, space-constrained, and thermally managed designs.

FAQ
What is the maximum continuous reverse current this Zener can handle at 3.6 V?
The MM5Z3V6T5GF is not rated for continuous reverse current at its Zener voltage; instead, it is characterized at IZ = 5 mA for specification. Its absolute maximum forward current is 200 mA, and total power dissipation is limited to 300 mW at 25 °C ambient - meaning sustained reverse current must be kept below ~83 mA to avoid exceeding Ptot at 3.6 V.
Can this diode be used in place of a TVS for ESD protection?
No - while MM5Z3V6T5GF withstands 40 W non-repetitive surges (100 µs square wave), it lacks the clamping speed, low dynamic impedance, and standardized ESD robustness (e.g., IEC 61000-4-2) of dedicated TVS diodes. It may serve as secondary clamping in combination with a fast TVS, but should not replace primary ESD protection.
How does the cathode marking align with PCB footprint polarity?
The cathode (terminal 1) is marked by a visible band on the diode body and corresponds to the rectangular pad or silkscreen 'K' indicator in the SOD523 footprint. On the PCB, this pad must connect to the higher-potential node (e.g., VBUS or regulated rail), while the anode (terminal 2) connects to GND or lower potential - reversing polarity prevents Zener operation and risks forward conduction damage.
Is this part qualified for automotive applications?
No - MM5Z3V6T5GF is not AEC-Q200 qualified and is explicitly designated as a general-purpose industrial/commercial Zener diode. Nexperia's documentation states that unless expressly marked "automotive qualified", products are unsuitable for safety-critical or automotive environments; users must perform full qualification if deploying in such contexts.
