Product details
Overview
MM3Z16VC from onsemi is a 16 V ±5% tolerance Zener diode in SOD−323FL package, rated for 200 mW power dissipation, with zener impedance of 37 Ω at 5 mA test current and reverse leakage current of 0.045 µA at 11.2 V, used for precision voltage regulation and reference in low-power analog circuits.
For engineers reviewing the MM3Z16VC datasheet, pinout, applications, or equivalent options, key selection criteria include zener voltage tolerance, dynamic impedance at IZT, thermal resistance (595 °C/W), junction temperature limit (150 °C), and SOD−323FL footprint compatibility in space-constrained PCB designs.
Technical Context
This device operates as a two-terminal voltage reference, maintaining stable output voltage across a defined reverse-bias current range (IZK = 1 mA to IZM ≈ 12.5 mA). Its zener breakdown mechanism provides predictable regulation with low temperature coefficient and tight ±5% initial tolerance.
Designed for surface-mount applications requiring minimal board area, the MM3Z16VC features matte tin finish, Pb-free construction, and RoHS compliance. Thermal performance is specified with RJA = 595 °C/W when mounted on PCB with minimum land pad - critical for derating in ambient temperatures up to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.2 V (min) to 16.8 V (max) at IZT = 5 mA - defines regulation band for precision reference use |
| Zener Impedance (ZZT) | 37 Ω max at IZT = 5 mA - determines output voltage stability under load variation |
| Power Dissipation (PD) | 200 mW - sets maximum continuous reverse power before thermal runaway |
| Reverse Leakage (IR) | 0.045 µA max at VR = 11.2 V - ensures minimal quiescent current in standby mode |
| Junction Temperature (TJ) | 150 °C max - constrains operating ambient and PCB copper area requirements |
| Thermal Resistance (RJA) | 595 °C/W - requires careful thermal pad design to sustain rated power at TA = 25 °C |
| Forward Voltage (VF) | 1.0 V max at IF = 10 mA - relevant for polarity-check or ESD protection circuit integration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B16 | Same 16 V nominal, ±5% tolerance, but SOD-323 package (not FL variant); RJA = 625 °C/W | Higher thermal resistance limits power handling in compact layouts | Acceptable where board layout allows marginally larger thermal relief |
| MMSZ5245B | 16 V nominal, ±5%, but SOD-123 package; PD = 500 mW; ZZT = 20 Ω @ 5 mA | Higher power rating and lower impedance, but 2.7× larger footprint | Preferred when higher current regulation or lower dynamic error is required |
Compared with BZX384-B16 and MMSZ5245B, the MM3Z16VC offers the smallest footprint among 16 V ±5% Zeners while maintaining adequate regulation accuracy and thermal performance for low-power signal conditioning - making it optimal for miniaturized, battery-sensitive designs where space is constrained but 200 mW is sufficient.

FAQ
What is the zener voltage tolerance of MM3Z16VC?
The MM3Z16VC has a nominal zener voltage of 16 V with a guaranteed tolerance of ±5%, meaning its actual VZ falls between 15.2 V and 16.8 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 all units shipped under this part number.
What is the maximum power dissipation for MM3Z16VC?
The MM3Z16VC is rated for a maximum power dissipation of 200 mW at TA = 25 °C, as specified in the Absolute Maximum Ratings table. Derating is required above 25 °C at 0.337 mW/°C (based on RJA = 595 °C/W), and operation must remain within the 150 °C maximum junction temperature limit to ensure reliability.
Does MM3Z16VC have RoHS and Pb-free compliance?
Yes, the MM3Z16VC is explicitly stated as Pb-free and RoHS compliant in the Features section of the onsemi datasheet. It uses matte tin (Sn) plating on its SOD−323FL terminals and meets EU Directive 2011/65/EU requirements without exemptions.
What is the reverse leakage current specification for MM3Z16VC?
The MM3Z16VC exhibits a maximum reverse leakage current (IR) of 0.045 µA at VR = 11.2 V, per the Electrical Characteristics table. This ultra-low leakage supports high-impedance reference networks and extends battery life in always-on sensor applications where current draw must be minimized.
What package type does MM3Z16VC use, and what are its dimensions?
The MM3Z16VC uses the SOD−323FL package (Case 477AB), measuring 2.0 mm × 1.25 mm × 0.9 mm with a cathode band on terminal 2. This ultra-thin, low-profile package is optimized for high-density PCB assembly and is distinct from standard SOD-323 due to its reduced height and enhanced thermal pad design.
