Product details
Overview
MM5Z27VT5GF from Nexperia is a 27 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 50 Ω typical differential resistance at IZ = 2 mA and 21.4–25.3 mV/K temperature coefficient range. It provides precision voltage regulation in space-constrained low-power analog rails and reference circuits.
For engineers reviewing the MM5Z27VT5GF datasheet, MM5Z27VT5GF pinout, MM5Z27VT5GF application, or MM5Z27VT5GF equivalent, this page delivers verified Zener parameters, cathode/anode terminal mapping, thermal resistance values (Rth(j-a) = 350 K/W), and real-world use cases in voltage clamping, overvoltage protection, and biasing networks.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable 27 V regulation across load and line variations. Its low 50 Ω differential resistance ensures minimal voltage drift under dynamic current changes (IZ = 2 mA), while the 21.4–25.3 mV/K temperature coefficient enables predictable thermal behavior in ambient ranges from −55 °C to +150 °C.
The device supports transient suppression via 40 W non-repetitive peak reverse power handling (tp = 100 µs, square wave), and its 50 pF capacitance at 1 MHz / 0 V enables compatibility with moderate-speed signal paths without introducing excessive coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 26.46 V to 27.54 V at IZ = 2 mA - defines regulation window for precision reference design |
| Differential Resistance (rdiff) | 50 Ω max at IZ = 2 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | 21.4 mV/K min to 25.3 mV/K max - quantifies VZ drift per degree Celsius over operating range |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C on FR4 PCB with 35 mm² Cu - sets continuous thermal limit for PCB layout |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W at tp = 100 µs, square wave - defines surge energy handling capability for transient clamping |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - constrains forward conduction loss in dual-direction protection schemes |
| Junction Temperature (Tj) | 150 °C max - establishes maximum allowable die temperature for reliability margin |
Pinout & Package
SOD523 (SC-79) ultra-small surface-mount plastic package with flat lead profile, 1.25 mm × 0.85 mm footprint, 0.65 mm height, and cathode band marking 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 operation |
Key Features
| Feature | Design Value |
|---|---|

| Ultra-compact SOD523 package | Supports high-density PCB layouts in wearables, IoT sensors, and portable medical devices where board space is constrained |
| Low 50 Ω differential resistance | Minimizes output voltage variation under ±1 mA load current shifts, improving stability in feedback references |
| 350 K/W junction-to-ambient thermal resistance | Defines required copper area (35 mm² at cathode tab) for safe 300 mW operation without derating |
| 27 V nominal working voltage | Targets mid-range industrial supply monitoring (e.g., 24 V system supervision) and analog front-end biasing |
Applications
| Power Supply Monitoring | Reference Voltage Generation |
|---|---|
Use Scenario: Monitoring 24 V DC input rail in industrial PLC modules to detect undervoltage/overvoltage faults. IC Role / Device Role / Timing Role: Zener diode acts as precision shunt clamp, triggering comparator threshold when rail exceeds 27 V. Use Value: 26.46–27.54 V regulation window ensures reliable trip point with margin against ripple and tolerance stack-up. |
Use Scenario: Providing stable 27 V reference for ADC biasing in battery-powered environmental sensor nodes. IC Role / Device Role / Timing Role: Functions as passive voltage reference source feeding op-amp buffer stage. Use Value: 50 Ω rdiff and ±2 % tolerance yield <0.5 % reference error across 0.5–5 mA operating range. |
| Overvoltage Protection | Signal Level Clamping |
Use Scenario: Protecting microcontroller GPIO pins from ESD-induced transients on 3.3 V I/O lines using series resistor + Zener clamp. IC Role / Device Role / Timing Role: Shunt limiter diverting surge current above 27 V to ground during fast transients. Use Value: 40 W PZSM rating handles IEC 61000-4-2 Level 4 contact discharge without degradation. |
Use Scenario: Limiting analog sensor output swing to prevent saturation in instrumentation amplifier inputs. IC Role / Device Role / Timing Role: Bidirectional clamp (with series diode) restricting signal excursion to ±27 V envelope. Use Value: 50 pF capacitance at 1 MHz avoids phase shift or bandwidth reduction in ≤100 kHz signal paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C27 | Same 27 V nominal, ±5 % tolerance, SOD523 package, but higher rdiff (100 Ω) and no specified PZSM. | Limited to static reference use; unsuitable for transient clamping due to missing surge rating. | Select when cost sensitivity outweighs regulation precision and surge robustness. |
| MMSZ5256ET1G | 27 V nominal, ±5 % tolerance, SOD-123 package (larger), 100 mW Ptot, rdiff = 45 Ω. | Requires more PCB area; lower power rating restricts use in sustained clamp scenarios. | Choose only if legacy SOD-123 footprint compatibility is mandatory and 300 mW is not required. |
Compared with BZX584-C27 and MMSZ5256ET1G, MM5Z27VT5GF offers superior voltage accuracy (±2 % vs. ±5 %), higher continuous power (300 mW vs. 200–100 mW), and verified 40 W surge capability-making it optimal for compact, high-reliability regulation and protection designs.

FAQ
What is the maximum continuous reverse current (IZ) this Zener can handle at 27 V regulation?
The datasheet specifies a maximum total power dissipation of 300 mW at 25 °C ambient. At 27 V, this corresponds to IZ = 300 mW / 27 V ≈ 11.1 mA continuous. Derating applies above 25 °C per the thermal resistance curve (Rth(j-a) = 350 K/W), limiting usable current in elevated ambient conditions.
Does MM5Z27VT5GF support bidirectional ESD protection?
No-it is a unidirectional Zener diode optimized for reverse-bias regulation. For bidirectional ESD clamping, a paired configuration (e.g., two Zeners anode-to-anode) or dedicated TVS diode like PESD5V0S1BA is required. The device's 1.1 V forward voltage and lack of symmetric breakdown preclude standalone bidirectional use.
How does the 21.4–25.3 mV/K temperature coefficient affect long-term reference stability?
Over a 100 °C junction temperature swing (25 °C to 125 °C), VZ shifts by approximately 2.14–2.53 V. This translates to ±4.2 % to ±4.7 % deviation from nominal 27 V-critical for high-accuracy references. System-level compensation (e.g., matched NTC thermistors or digital calibration) is recommended where <1 % drift is required.
Can MM5Z27VT5GF be soldered using standard lead-free reflow profiles?
Yes-the SOD523 package is qualified for JEDEC J-STD-020-compliant lead-free reflow. Peak temperature must not exceed 260 °C, with time above liquidus ≤ 60 seconds. Figure 10 in the datasheet provides the exact solder land pattern (1.4 mm × 0.5 mm pads, 0.4 mm spacing), and thermal relief design must accommodate Rth(j-sp) = 65 K/W to the cathode solder point.
