Product details
Overview
MM3Z3V0T1 from onsemi is a 3.0 V ±0.2 V, 200 mW surface-mount Zener diode in SOD−323 package, rated for 5 mA test current and 100 Ω dynamic impedance at IZT, used for precision voltage regulation and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the MM3Z3V0T1 datasheet, MM3Z3V0T1 pinout, MM3V3V0T1 application, or MM3Z3V0T1 equivalent, key selection criteria include zener voltage tolerance (±0.2 V), low leakage (10 µA @ VR = 1.0 V), ESD robustness (>16 kV HBM), thermal resistance (635 °C/W), and Pb-free SOD−323 footprint compatibility with high-density PCB assembly.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp voltage at nominal 3.0 V with temperature coefficient of −3.5 mV/°C. It delivers stable regulation under DC or low-frequency transient conditions with no external bias circuitry required.
Designed for passive clamping and reference functions, it features cathode-anode polarity marking, UL 94 V−0 flammability rating, and 260°C soldering tolerance. Its 1.7 mm × 1.25 mm × 0.9 mm body enables integration into cellular handsets, wearables, and IoT sensor nodes where board area is critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V0,115 | Same 3.0 V nominal, 200 mW rating, but SOD-323 package with 100 Ω ZzT @ 5 mA and 5 µA IR @ 1 V | Lower leakage improves battery life in always-on sensing; identical footprint enables drop-in replacement | Select when sub-5 µA standby leakage is required and BOM consolidation with Nexperia portfolio is preferred |
| MMSZ3V0T1G | 3.0 V nominal, 350 mW rating in SOD-123 package; larger footprint (2.7 mm × 1.4 mm) and higher power dissipation | Higher power handling suits industrial control inputs; incompatible pad layout requires PCB redesign | Select when sustained 350 mW dissipation is needed and board space permits SOD-123 placement |
Compared with BZX384-B3V0,115, MM3Z3V0T1 offers slightly higher leakage but identical regulation precision and footprint; versus MMSZ3V0T1G, it trades power capacity for 35% smaller area-critical for miniaturized wearables and hearing aids.

FAQ
What is the exact Zener voltage tolerance of MM3Z3V0T1 at 5 mA test current?
The MM3Z3V0T1 has a guaranteed Zener voltage range of 2.8 V to 3.2 V at IZT = 5 mA, corresponding to a nominal 3.0 V with ±0.2 V absolute tolerance. This specification is validated per onsemi's MM3Z2V4T1/D datasheet Rev. 7, page 2, and defines the device's regulation window under standard DC test conditions.
Can MM3Z3V0T1 be used as a voltage reference for ADCs in battery-powered devices?
Yes, MM3Z3V0T1 is suitable as a low-cost voltage reference for 8–10 bit ADCs in battery-powered devices due to its tight 2.8–3.2 V tolerance and low 10 µA leakage at 1.0 V. However, designers must account for its −3.5 mV/°C temperature coefficient and ensure adequate decoupling, as MM3Z3V0T1 lacks active compensation found in bandgap references.
What is the maximum allowable soldering temperature and duration for MM3Z3V0T1?
The MM3Z3V0T1 is rated for a maximum case temperature of 260°C for 10 seconds during reflow soldering, per its mechanical characteristics table. This aligns with standard lead-free reflow profiles and ensures integrity of the void-free transfer-molded plastic case and Pb-free plating on the SOD−323 terminals.
Does MM3Z3V0T1 have a specified junction-to-ambient thermal resistance?
Yes, MM3Z3V0T1 has a specified RJA of 635 °C/W when mounted on an FR-5 board at TA = 25°C, as stated in the Maximum Ratings table. This value assumes minimum pad design per note 1 and is critical for calculating junction temperature rise under steady-state power dissipation up to 200 mW.
Is MM3Z3V0T1 compliant with RoHS and REACH regulations?
Yes, the "G" suffix in MM3Z3V0T1 indicates a Pb-free package compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The device uses Sn-only or Pb-Sn plating per datasheet mechanical specifications, and onsemi provides material declarations supporting full regulatory conformance.
