Product details
Overview
MM5Z30VT5GF from Nexperia is a 30 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 21.0 Ω typical differential resistance at IZ = 2 mA and 24.4–29.4 V working voltage range - used for precision voltage reference and overvoltage clamping in low-power analog sensor interfaces.
For engineers reviewing the MM5Z30VT5GF datasheet, MM5Z30VT5GF pinout, MM5Z30VT5GF application, or MM5Z30VT5GF equivalent, this device serves as a compact, stable voltage regulation element in space-constrained DC biasing, ESD protection feedback paths, and reference node stabilization where thermal resistance to solder point (65 K/W) and low capacitance (50 pF at 1 MHz) are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal 30 V regulation voltage at 2 mA test current, exhibiting a temperature coefficient of +24.4 mV/K to +29.4 mV/K across its operating range and maintaining < 0.05 Ω/V dynamic impedance slope per datasheet Table 9. It is designed for stable DC reference generation under low-current conditions (≤200 mA forward, ≤2 mA Zener test current).
The device features ultra-low junction-to-solder-point thermal resistance (65 K/W), enabling reliable operation on FR4 PCBs with minimal copper area (35 mm² at cathode tab), and supports transient surge handling up to 40 W for 100 µs square-wave pulses at 25 °C ambient - critical for input-stage transient suppression in portable instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 29.4 V min / 30.6 V max at IZ = 2 mA - defines tight 30 V regulation window for reference stability |
| Differential Resistance rdiff | 21.0 Ω typical at IZ = 2 mA - ensures low output impedance for minimal voltage shift under load variation |
| Power Dissipation Ptot | 300 mW at Tamb = 25 °C - sets continuous DC bias limit on standard FR4 PCB |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 µs square wave - enables single-event transient clamping without failure |
| Reverse Current IR | ≤ 80 µA at VR = 24 V - guarantees low leakage in high-impedance reference nodes |
| Diode Capacitance Cd | 50 pF at f = 1 MHz, VR = 0 V - preserves signal integrity in RF-adjacent or fast-switching circuits |
| Thermal Resistance Rth(j-sp) | 65 K/W junction-to-solder-point - allows predictable thermal rise with minimal board copper |
Pinout & Package
SOD523 (SC-79) ultra-small flat-lead surface-mount package: 1.25 mm × 0.85 mm footprint, 0.65 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - reverse-biased during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for voltage reference function |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables precise reference without post-manufacturing trimming in 30 V systems |
| Low 21.0 Ω differential resistance | Maintains regulation accuracy within ±0.1 V under ±1 mA load current change |
| 40 W non-repetitive surge rating | Clamps ESD transients (IEC 61000-4-2 Level 4) without degradation when placed at IC input pins |
| 50 pF junction capacitance | Minimizes loading on 10 MHz+ signal paths in ADC reference buffers or op-amp feedback networks |
| 65 K/W junction-to-solder-point Rth | Permits thermal design on minimal PCB copper - no thermal pad required for 300 mW operation |
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-C30 | Same 30 V nominal, ±5 % tolerance, higher 500 mW Ptot, larger SOD323 package | Requires more PCB area; better suited for higher-power biasing where thermal margin >65 K/W is needed | Select when board layout permits larger footprint and system demands >300 mW continuous dissipation |
| MMSZ5262T1G | 30 V nominal, ±5 % tolerance, 500 mW Ptot, SOD-123 package, 35 Ω rdiff | Higher differential resistance increases regulation error under load; less precise for reference use | Choose only for cost-sensitive, non-critical clamping where ±5 % VZ and 35 Ω rdiff are acceptable |
Compared with BZX584-C30 and MMSZ5262T1G, MM5Z30VT5GF offers tighter ±2 % tolerance, lower 21.0 Ω rdiff, and ultra-compact SOD523 footprint - making it optimal for high-precision, space-constrained reference designs where thermal management must be achieved with minimal copper area.

FAQ
What is the maximum continuous Zener test current for MM5Z30VT5GF?
The device is characterized at IZ = 2 mA per Table 9, and its 300 mW total power dissipation limits continuous Zener current to approximately 10 mA at 30 V (P = V × I). However, sustained operation above 2 mA increases self-heating and degrades regulation accuracy due to temperature coefficient effects - recommended operating current is 1–5 mA for optimal stability.
Can MM5Z30VT5GF be used in place of a 30 V TL431-based shunt regulator?
No - MM5Z30VT5GF is a two-terminal passive Zener diode without internal amplification or adjustable feedback. It lacks the 2.5 V reference, high open-loop gain, and sink current capability of the TL431. It can replace TL431 only in simple fixed-voltage clamping or biasing roles where ±2 % tolerance and no active regulation are acceptable.
How does the cathode marking align with the SOD523 package outline?
The cathode (pin 1) is identified by a visible bar printed on the top surface of the SOD523 package, positioned adjacent to the shorter end of the rectangular body. As shown in Figure 9, the bar aligns with the "cathode band" label and corresponds to the leftmost terminal when the marking is oriented upright and readable - matching the pin 1 designation in Table 2.
Is MM5Z30VT5GF suitable for automotive applications?
No - this device is not AEC-Q200 qualified or specified for automotive use. The datasheet explicitly states "Non-automotive qualified products" in Section 14, and no automotive-grade screening, testing, or qualification data is provided. Use only in commercial or industrial environments where ambient temperature remains within −55 °C to +150 °C and no safety-critical function is assigned.
