Product details
Overview
MM3Z62VC from onsemi is a 62 V ±5% tolerance Zener diode in SOD−323FL package, rated for 200 mW power dissipation, with 202 Ω dynamic impedance at 5 mA test current and 0.045 µA reverse leakage at 43.4 V. It provides precision voltage regulation in low-power reference and protection circuits.
For engineers reviewing the MM3Z62VC datasheet, pinout, applications, or equivalent options, key selection criteria include zener voltage tolerance, thermal resistance (595 °C/W), junction temperature limit (150 °C), and SOD−323FL footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference, conducting in reverse breakdown to clamp or regulate voltage at its nominal 62 V zener point. Its 5 mA test current (IZT) and 0.5 mA knee current (IZK) define stable regulation boundaries under low-current conditions.
The SOD−323FL package enables surface-mount integration with minimal board area, while the matte tin finish ensures solderability and RoHS compliance. Thermal performance is specified for mounting on PCB with minimum land pad, yielding 595 °C/W junction-to-ambient resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 58.9 V min / 62 V typ / 65.1 V max at 5 mA - defines regulation band for precision reference use |
| Tolerance | ±5% - ensures predictable voltage clamping across production lots |
| Zener Impedance (ZZT) | 202 Ω max at IZT = 5 mA - indicates regulation stiffness under small-signal load variation |
| Reverse Leakage (IR) | 0.045 µA max at VR = 43.4 V - confirms low standby power loss in high-impedance bias networks |
| Power Dissipation (PD) | 200 mW - sets maximum continuous DC or pulse power handling without derating |
| Junction Temperature (TJ) | 150 °C max - determines thermal design margin for ambient and self-heating conditions |
| Thermal Resistance (RJA) | 595 °C/W - requires careful PCB copper area planning to avoid exceeding TJ at full PD |
Pinout & Package
SOD−323FL is a 2-pin surface-mount plastic package with cathode stripe marking; dimensions conform to CASE 477AB outline. Mounting requires minimum land pad per onsemi thermal specification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B62 | Same 62 V ±5%, but SOD-323 package with 400 mW rating and higher 300 Ω ZZT | Higher power handling supports longer surge duration; less stable regulation at low currents | Select when robustness to repetitive transients outweighs tight low-current regulation |
| MMSZ5255B | 62 V ±5%, SOD-123 package, 500 mW rating, 250 Ω ZZT, 0.1 µA IR at 43.4 V | Larger footprint eases hand-soldering; higher leakage reduces suitability for ultra-low-power sleep modes | Prefer for manual assembly or where thermal mass improves surge survivability |
Compared with BZX384-B62 and MMSZ5255B, the MM3Z62VC offers the smallest PCB footprint and lowest leakage, making it optimal for space-constrained, battery-sensitive designs where 200 mW power handling suffices.

FAQ
What is the zener voltage tolerance of MM3Z62VC?
The MM3Z62VC has a zener voltage tolerance of ±5% at 25 °C, with a nominal value of 62 V, a minimum of 58.9 V, and a maximum of 65.1 V when tested at 5 mA. This tolerance is confirmed in the Electrical Characteristics table of the official onsemi datasheet (Rev. 3, August 2023). The MM3Z62VC maintains this specification across its qualified operating temperature range.
What package type does MM3Z62VC use?
The MM3Z62VC uses the SOD−323FL surface-mount package, also designated as CASE 477AB, with matte tin (Sn) finish and Pb-free/RoHS compliance. Its mechanical dimensions and land pattern requirements are defined in onsemi's official package outline documentation. The MM3Z62VC is shipped in tape-and-reel format (3,000 units per reel).
What is the maximum power dissipation rating for MM3Z62VC?
The MM3Z62VC has a maximum power dissipation (PD) rating of 200 mW at 25 °C ambient temperature. Derating is required above 25 °C per the thermal resistance RJA = 595 °C/W, meaning usable power drops linearly as ambient or junction temperature rises. This rating applies to the MM3Z62VC under standard PCB mounting conditions with minimum land pad.
How does the zener impedance of MM3Z62VC affect regulation stability?
The MM3Z62VC exhibits a maximum zener impedance (ZZT) of 202 Ω at 5 mA test current, indicating moderate regulation stiffness. Lower impedance values would yield tighter voltage control under varying load currents; this value makes the MM3Z62VC suitable for applications with modest load variation, such as reference biasing or clamping, but not for high-precision active regulation loops. The MM3Z62VC's impedance is measured using 60-Hz AC superimposed on DC bias.
What is the reverse leakage current specification for MM3Z62VC?
The MM3Z62VC specifies a maximum reverse leakage current (IR) of 0.045 µA at a reverse voltage (VR) of 43.4 V and 25 °C. This ultra-low leakage supports energy-sensitive applications like battery-backed sensors and sleep-mode circuits. The value is verified per onsemi's test methodology and applies directly to the MM3Z62VC - not extrapolated from adjacent family members.
