Product details
Overview
MM3Z2V7C from onsemi is a 2.7 V ±5% Zener diode in SOD−323FL package, rated for 200 mW power dissipation, with 94 Ω zener impedance at 5 mA test current and 18 µA reverse leakage at 1 V. It provides precision voltage regulation in low-power biasing and reference circuits for portable sensors and battery-powered microcontrollers.
For engineers reviewing the MM3Z2V7C datasheet, pinout, applications, or equivalent options, key selection criteria include its tight 2.7 V nominal zener voltage, low 595 °C/W thermal resistance, SOD−323FL footprint compatibility, and RoHS-compliant matte tin finish - all critical for space-constrained, thermally sensitive designs.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain stable 2.7 V across its terminals when biased above its knee current (IZK = 1 mA). Its zener impedance of 94 Ω at IZT = 5 mA defines regulation stiffness under dynamic load changes.
The MM3Z2V7C is characterized at TA = 25 °C with pulse-tested VZ (10 ms), and exhibits 18 µA reverse leakage (IR) at VR = 1 V - confirming low standby current draw essential for energy-efficient systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Power Dissipation (PD) | 200 mW - limits maximum continuous power handling on standard PCB land pads |
| Zener Impedance (ZZT) | 94 Ω at IZT = 5 mA - determines output voltage variation under small-signal load transients |
| Reverse Leakage (IR) | 18 µA at VR = 1 V - confirms minimal quiescent current in standby mode |
| Thermal Resistance (RJA) | 595 °C/W - defines junction-to-ambient temperature rise per milliwatt in typical SMD mounting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V7 | Same 2.7 V ±5%, but SOD-323 package (not FL variant); RJA = 625 °C/W | Marginally higher thermal resistance; identical electrical specs at 25 °C | Acceptable where board layout allows standard SOD-323 pad geometry |
| MMSZ4677 | 2.7 V ±5%, SOD-123 package; PD = 500 mW; ZZT = 100 Ω at 20 mA | Higher power rating but larger footprint; optimized for higher-current regulation | Preferred when >200 mW dissipation or >5 mA regulation current is required |
Compared with BZX384-B2V7 and MMSZ4677, the MM3Z2V7C offers the smallest footprint (SOD−323FL), lowest profile (0.7 mm), and best thermal performance per unit area - making it optimal for ultra-dense, low-power PCB layouts where space and thermal budget are constrained.

FAQ
What is the exact zener voltage tolerance for MM3Z2V7C?
The MM3Z2V7C has a nominal zener voltage of 2.7 V with a guaranteed tolerance of ±5%, meaning its measured VZ falls between 2.57 V and 2.84 V when tested at IZT = 5 mA and TA = 25 °C. This tolerance is confirmed in the Electrical Characteristics table of the official onsemi datasheet (Rev. 3, August 2023) and applies to every unit shipped.
Can MM3Z2V7C be used in place of a 2.5 V Zener diode?
No - the MM3Z2V7C is specified exclusively for 2.7 V regulation and is not interchangeable with 2.5 V Zeners such as MM3Z2V4C. Its minimum VZ is 2.57 V, exceeding the maximum 2.63 V of a ±5% 2.5 V part. Substituting would cause overvoltage in circuits relying on precise 2.5 V thresholds, potentially disrupting ADC references or reset logic.
What is the maximum continuous reverse current the MM3Z2V7C can handle?
The MM3Z2V7C supports a maximum regulator current (IZM) of PD/VZ ≈ 74 mA (200 mW ÷ 2.7 V), but this is a theoretical limit under ideal thermal conditions. In practice, continuous operation above 5–10 mA requires careful thermal design due to its 595 °C/W RJA. For sustained regulation, IZ should remain ≤5 mA unless heatsinking or forced airflow is implemented.
Does MM3Z2V7C have a specified forward voltage?
Yes - the MM3Z2V7C has a maximum forward voltage (VF) of 1.0 V at IF = 10 mA, per the Absolute Maximum Ratings table. This value is relevant when the device is used in forward conduction (e.g., ESD protection clamping), though its primary function is reverse-bias zener regulation.
Is MM3Z2V7C suitable for automotive applications?
The MM3Z2V7C meets AEC-Q200 stress test requirements for passive components and operates up to TJ = 150 °C, making it suitable for under-hood and cabin modules where ambient temperatures reach 105 °C. However, it is not AEC-Q101 qualified as a discrete semiconductor; designers must validate system-level robustness per ISO/TS 16949 requirements.
