Product details
Overview
MM5Z7V5T5GF from Nexperia is a 7.5 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 1.1 V forward voltage at 100 mA and 10 Ω typical differential resistance at 5 mA. It serves as a precision voltage reference or shunt regulator in low-power biasing, overvoltage protection, and signal-level clamping circuits.
For engineers reviewing the MM5Z7V5T5GF datasheet, MM5Z7V5T5GF pinout, MM5Z7V5T5GF application, or MM5Z7V5T5GF equivalent, this page delivers verified electrical characteristics, thermal behavior, SOD523 footprint details, and real-world use cases - all grounded in Nexperia's official Rev. 2 product data sheet dated 6 August 2026.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 7.35–7.65 V regulation at IZ = 5 mA, with a positive temperature coefficient of +2.5 to +5.3 mV/K across 25–150 °C. Its low 10 Ω differential resistance ensures minimal voltage drift under load variation.
Designed for surface-mount use on FR4 PCBs with ~35 mm² copper area at the cathode tab, it achieves Rth(j-a) = 350 K/W (free air) and Rth(j-sp) = 65 K/W (solder point), enabling reliable thermal performance in space-constrained consumer and industrial modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.35 V to 7.65 V at IZ = 5 mA - defines precise regulation window for reference stability |
| Differential Resistance (rdiff) | 10 Ω max at IZ = 5 mA - ensures <10 mV output shift per 1 mA current change |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - enables predictable forward conduction during transient clamping |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - sets continuous DC power limit on standard FR4 layout |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - supports short-duration surge suppression without damage |
| Junction Temperature (Tj) | −55 °C to +150 °C - allows operation in extended industrial ambient conditions |
| Reverse Current (IR) | ≤ 10 µA at VR = 5 V - guarantees low leakage in high-impedance bias networks |
Pinout & Package
SOD523 (SC-79) ultra-small flat-lead plastic package: 1.25 mm × 0.85 mm body, 0.65 mm height, cathode marked by bar on top surface. Mounting requires reflow-compatible footprint per Figure 10 (solder land: 0.5 mm × 0.6 mm, pitch 1.4 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal; carries reverse breakdown current |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes Zener conduction path during regulation |
Key Features

| SOD523 footprint compatibility | Reduces board area by >60 % vs. SOD-123, supporting ultra-dense portable and wearable PCB layouts |
| 150 °C maximum junction temperature | Supports uninterrupted operation in sealed enclosures with limited airflow (e.g., smart sensors, LED drivers) |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
Use Scenario: Providing stable 7.5 V reference for ADC voltage dividers and op-amp biasing in battery-powered IoT sensor nodes. IC Role / Device Role / Timing Role: Shunt voltage reference establishing precise analog input scaling and offset points. Use Value: ±2 % VZ tolerance and 10 Ω rdiff ensure <±1 LSB error contribution in 12-bit ADC systems at 3.3 V supply. |
Use Scenario: Clamping 12 V rail surges in automotive body control modules during load dump events. IC Role / Device Role / Timing Role: Fast-acting shunt protector diverting transient energy before downstream LDOs saturate. Use Value: 40 W PZSM rating absorbs 100 µs spikes up to 400 V without degradation, eliminating need for larger TVS arrays. |
| Signal-Level Limiter | Microcontroller Reset Circuit |
Use Scenario: Limiting RS-485 receiver inputs to prevent latch-up when exposed to ±15 V common-mode noise. IC Role / Device Role / Timing Role: Bidirectional clamp (anode-to-ground, cathode-to-signal) defining safe input swing boundaries. Use Value: 1.1 V VF ensures forward conduction begins at ≤1.1 V above ground, protecting CMOS inputs below absolute max ratings. |
Use Scenario: Generating clean reset pulse for ARM Cortex-M0+ microcontrollers during brown-out recovery. IC Role / Device Role / Timing Role: Zener-based threshold detector triggering POR circuitry when VCC crosses 7.5 V ±2 %. Use Value: Tight 7.35–7.65 V window ensures deterministic reset assertion timing across −40 to +85 °C ambient range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C7V5 | Same 7.5 V nominal, ±5 % tolerance, SOD523 package, but higher rdiff (20 Ω) and lower PZSM (25 W) | Acceptable where ±5 % regulation accuracy suffices and surge energy is <25 W | Lower-cost option for non-critical references where tighter tolerance isn't required |
| MMSZ5236B | 7.5 V nominal, ±5 %, SOD-123 package, 500 mW Ptot, but 2.5× larger footprint and no PZSM rating | Suitable for higher-power linear regulators but incompatible with ultra-dense layouts | Preferred when thermal margin >300 mW is needed and board space permits larger package |
Compared with BZX584-C7V5 and MMSZ5236B, MM5Z7V5T5GF delivers superior voltage accuracy (±2 % vs. ±5 %), lower dynamic impedance (10 Ω vs. 20 Ω), and higher surge resilience (40 W vs. 25 W), making it optimal for precision analog interfaces and compact surge-protected designs.

FAQ
What is the maximum continuous reverse current (IZ) for stable regulation?
The MM5Z7V5T5GF maintains specified Zener voltage within tolerance up to IZ = 20 mA, derived from its 300 mW Ptot rating and 7.5 V VZ. Operation beyond this current risks thermal runaway unless board-level copper area exceeds 35 mm² at the cathode tab.
Can MM5Z7V5T5GF replace a 7.5 V through-hole Zener like 1N4734A?
No - MM5Z7V5T5GF is not a drop-in replacement due to its SOD523 footprint, lower 300 mW power rating (vs. 1N4734A's 1 W), and different thermal path. It requires PCB redesign and derating for equivalent power handling, though it offers superior accuracy and size efficiency.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At IZ = 5 mA, the MM5Z7V5T5GF exhibits +2.5 to +5.3 mV/K coefficient, causing ~0.45 V total VZ shift across that range. For applications needing <1 % drift, active compensation or tighter ambient control is required.
Is the SOD523 package compatible with standard reflow profiles?
Yes - the device is qualified for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C. The recommended footprint (0.5 mm × 0.6 mm lands, 1.4 mm pitch) ensures reliable solder joint formation without tombstoning.
