Product details
Overview
MM3Z13VT1 from onsemi is a 13.25 V nominal Zener voltage regulator diode in SOD−323 package, rated for 200 mW steady-state power dissipation at 25°C, with 30 Ω maximum dynamic impedance at 5 mA test current and 0.1 µA reverse leakage at 8.0 V. It provides precision voltage reference and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the MM3Z13VT1 datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±0.85 V), thermal resistance (635 °C/W), ESD rating (>16 kV HBM), low capacitance (120 pF at 0 V), and Pb-free SOD−323 footprint compatibility with high-density PCB layouts.
Technical Context
The MM3Z13VT1 operates as a two-terminal voltage reference device, conducting in reverse breakdown to clamp or regulate voltage across its cathode-anode terminals. Its Zener mechanism delivers stable regulation within ±0.85 V of nominal 13.25 V at IZT = 5 mA, with temperature coefficient of +7.0 mV/°C.
Designed for surface-mount use on FR-4 boards, it features a void-free transfer-molded plastic case (UL 94 V−0), Pb−Sn or Sn-only plating, and 260°C soldering tolerance for 10 seconds. Polarity is marked by a cathode band, and mounting position is unrestricted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.4 V min / 13.25 V nom / 14.1 V max @ IZT = 5 mA - defines regulation window for precision reference or clamping |
| Power Dissipation (PD) | 200 mW @ TA = 25°C - limits continuous current to ~15 mA at 13.25 V without derating |
| Zener Impedance (ZZT) | 30 Ω max @ IZT = 5 mA - determines AC regulation stability under varying load conditions |
| Reverse Leakage (IR) | 0.1 µA max @ VR = 8.0 V - ensures minimal standby current in voltage-sense or bias networks |
| Capacitance (C) | 120 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and signal integrity in RF-adjacent circuits |
| ESD Rating | Class 3 (>16 kV) per HBM - supports robust handling in automated assembly and end-user environments |
| Package | SOD−323 (Case 477−02) - 1.7 mm × 1.25 mm × 0.9 mm footprint ideal for ultra-compact portable designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B13,115 | 13 V nominal, 300 mW rating, SOD-323, 20 Ω ZZT @ 5 mA | Higher power margin but wider VZ tolerance (±5%) vs. MM3Z13VT1's ±0.85 V | Preferred where thermal headroom matters more than tight voltage accuracy |
| MMSZ4686T1G | 13 V nominal, 500 mW rating, SOD-123, 30 Ω ZZT @ 10 mA | Larger SOD-123 footprint (3.5 mm × 1.6 mm) and higher leakage (1 µA @ 10.4 V) | Used when board layout allows larger package and higher power handling is required |
Compared with BZX384-B13,115 and MMSZ4686T1G, the MM3Z13VT1 offers tighter voltage tolerance and lower leakage in the smallest SOD−323 footprint, making it optimal for miniaturized, low-power, high-accuracy reference designs where board area is constrained.

FAQ
What is the nominal Zener voltage and tolerance of the MM3Z13VT1?
The MM3Z13VT1 has a nominal Zener voltage of 13.25 V with a guaranteed range of 12.4 V to 14.1 V at 5 mA test current. This ±0.85 V tolerance reflects tight process control for precision reference applications, and the value is measured under pulsed conditions at 25°C ambient per the official onsemi datasheet.
Does the MM3Z13VT1 support Pb-free assembly processes?
Yes, the MM3Z13VT1 is available in a Pb-free version denoted by the "G" suffix (MM3Z13VT1G), with Sn-only plating compatible with standard lead-free reflow profiles. The device withstands 260°C for 10 seconds during soldering, meeting JEDEC J-STD-020 requirements.
What is the maximum reverse leakage current specification for the MM3Z13VT1?
The MM3Z13VT1 specifies a maximum reverse leakage current of 0.1 µA at a reverse voltage of 8.0 V. This low leakage supports ultra-low-power bias networks and precision voltage dividers where standby current must remain below 100 nA.
How does the thermal resistance of the MM3Z13VT1 affect its power handling capability?
The MM3Z13VT1 has a junction-to-ambient thermal resistance of 635 °C/W. At 25°C ambient, this limits continuous dissipation to 200 mW; above that temperature, power must be linearly derated by 1.5 mW/°C, reducing usable power to ~125 mW at 75°C ambient.
Can the MM3Z13VT1 be used as a substitute for higher-voltage Zeners like the MM3Z15VT1 in the same circuit?
No - the MM3Z13VT1 is not a drop-in substitute for MM3Z15VT1 due to its distinct 13.25 V nominal Zener voltage versus 15 V. Substitution would shift clamping thresholds by ~1.75 V, potentially violating system overvoltage protection margins or reference accuracy requirements.
