Product details
Overview
MM3Z62VT1GX from Nexperia is a 62 V ±5 % tolerance Zener diode in SOD323 (SC-76) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, with 0.05 Ω differential resistance at IZ = 2 mA and temperature coefficient of +0.4 mV/K. It provides precision voltage regulation in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the MM3Z62VT1GX datasheet, MM3Z62VT1GX pinout, MM3Z62VT1GX application, or MM3Z62VT1GX equivalent, this page delivers verified electrical characteristics, thermal behavior, cathode/anode terminal mapping, and real-world use cases in voltage clamping, supply rail stabilization, and signal-level referencing.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 62 V (min 58.0 V, max 66.0 V at IZ = 2 mA), exhibiting low dynamic impedance (0.05 Ω) and stable temperature coefficient (+0.4 mV/K) across its operating current range. Its junction-to-ambient thermal resistance is 415 K/W on FR4 PCB.
The device supports surge handling up to 40 W for 100 µs square-wave pulses at Tamb = 25 °C, and maintains reverse leakage ≤ 450 µA at VR = 43.4 V. Forward voltage is ≤ 1.1 V at IF = 100 mA under pulsed conditions (tp ≤ 300 µs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 58.0 V to 66.0 V at IZ = 2 mA - defines precise clamping threshold for 62 V nominal rail protection |
| Differential Resistance rdiff | 0.05 Ω at IZ = 2 mA - ensures minimal voltage shift under load variation in reference circuits |
| Temperature Coefficient SZ | +0.4 mV/K - enables predictable drift compensation in temperature-sensitive analog designs |
| Total Power Dissipation Ptot | 300 mW at Tamb = 25 °C - sets continuous DC power limit for thermal design on standard FR4 PCB |
| Non-repetitive Peak Reverse Power | 40 W for tp = 100 µs - supports transient overvoltage suppression without failure |
| Reverse Leakage IR | ≤ 450 µA at VR = 43.4 V - guarantees low standby current in high-impedance bias networks |
| Junction Temperature Range | −55 °C to +150 °C - allows operation in extended industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B62,115 (Nexperia) | Same 62 V rating, ±5 % tolerance, but SOD323 package with 200 mW Ptot and higher rdiff (1.5 Ω) | Limited to lower-power bias networks; unsuitable for surge-heavy clamping | Select when lower cost and legacy footprint compatibility outweigh surge capability needs |
| MMBZ5259BS-7-F (Diodes Inc.) | 62 V rating, ±5 %, SOT-23 package, 350 mW Ptot, but rdiff = 10 Ω and no published SZ | Higher impedance causes greater regulation error under load; less predictable thermal drift | Prefer only if SOT-23 board space constraints override stability and precision requirements |
Compared with BZX384-B62,115 and MMBZ5259BS-7-F, MM3Z62VT1GX delivers superior regulation fidelity (0.05 Ω vs ≥1.5 Ω rdiff) and quantified thermal stability (+0.4 mV/K), making it optimal for precision reference and high-surge industrial clamping where voltage accuracy and transient resilience are critical.

FAQ
What is the maximum continuous reverse current for MM3Z62VT1GX at 25 °C ambient?
The device supports up to 4.8 mA continuous reverse current at VZ = 62 V to maintain 300 mW power dissipation limit. At higher currents, thermal derating applies per Rth(j-a) = 415 K/W; exceeding this risks junction overheating beyond 150 °C.
Can MM3Z62VT1GX be used in bidirectional TVS configurations?
No - MM3Z62VT1GX is a unidirectional Zener diode optimized for reverse-bias regulation. For bidirectional transient suppression, a dedicated TVS diode such as PESD5V0S1BA should be used instead, as Zener devices lack symmetric clamping capability.
How does the +0.4 mV/K temperature coefficient affect long-term reference stability?
At a 50 °C ambient rise, the Zener voltage shifts +20 mV (0.4 mV/K × 50 K), representing ~0.032 % of 62 V. This drift is fully characterized and predictable, enabling software or hardware compensation in metrology-grade applications where sub-0.1 % accuracy is required.
Is the SOD323 package compatible with standard automated pick-and-place equipment?
Yes - the SOD323 (SC-76) package has standardized dimensions (2.7 mm × 1.6 mm × 1.1 mm) and lead pitch (1.35 mm), and is supported by major placement machines using IPC-7351B-compliant footprints. Reflow profiles must follow Nexperia's recommended thermal profile for plastic SMD packages.
