Product details
Overview
MM5Z13VT1G from onsemi is a 13.25 V nominal Zener voltage regulator diode in SOD-523 package, rated for 500 mW steady-state power dissipation at 25 °C, with ±5% tolerance (12.4–14.1 V), 30 Ω maximum Zener impedance at 5 mA test current, and 0.1 µA reverse leakage at 10.4 V. It provides precision voltage reference and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the MM5Z13VT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its 13.25 V regulation point, SOD-523 footprint compatibility, 16 kV HBM ESD rating, thermal derating behavior above 25 °C, and suitability for low-power biasing and clamping in battery-powered systems.
Technical Context
This device operates as a two-terminal, silicon planar Zener diode optimized for stable reverse-bias voltage regulation. Its breakdown mechanism is controlled avalanche for voltages ≥6.2 V, ensuring predictable temperature coefficient (+7.0 mV/°C) and low dynamic impedance (30 Ω @ 5 mA).
The SOD-523 package enables high-density PCB layouts with minimal thermal mass; junction-to-ambient thermal resistance is 250 °C/W on FR-4 (1 cm² pad), requiring careful power derating above 25 °C per Figure 1. It is Pb-free, RoHS-compliant, and qualified to AEC-Q101 when ordered as SZ prefix variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.25 V nominal (12.4–14.1 V range at IZT = 5 mA); defines precise clamping/reference level in bias networks. |
| Power Dissipation (PD) | 500 mW at TA = 25 °C; derates linearly at 4.0 mW/°C above 25 °C - limits continuous clamp duty in thermal-limited designs. |
| Zener Impedance (ZZT) | 30 Ω max @ IZT = 5 mA; determines regulation stiffness - lower values improve load/line transient response. |
| Reverse Leakage (IR) | 0.1 µA max @ VR = 10.4 V; ensures minimal quiescent current in standby circuits. |
| ESD Rating | Class 3 (>16 kV) per HBM; supports robust handling in automated assembly and end-user environments without external protection. |
| Package | SOD-523 (1.20 × 0.80 × 0.60 mm); enables <1.0 mm² board area usage - critical for ultra-compact mobile and wearable PCBs. |
| Temperature Coefficient | +7.0 mV/°C @ IZT; positive drift allows predictable compensation in temperature-sensitive references. |
Pinout & Package
SOD-523 surface-mount package: cathode marked with polarity band (Pin 1), anode unmarked (Pin 2); body dimensions 1.20 mm × 0.80 mm × 0.60 mm; 100% matte tin lead finish; MSL 1 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs. |
| 2 (Unmarked End) | Anode | Connected to circuit ground or lower-potential rail; completes bias path for regulation current. |
Key Features
| Feature | Design Value |
|---|---|
| Standard Tolerance Zener Series | ±5% VZ tolerance (12.4–14.1 V) - eliminates need for post-assembly trimming in cost-sensitive consumer designs. |
| High ESD Robustness | 16 kV HBM rating - reduces risk of field failure in handheld devices exposed to human contact discharge. |
| Low Profile & Miniature Footprint | 0.60 mm height and 0.96 mm² area - enables placement beneath connectors or in tight BGA escape zones. |
| Pb-Free & RoHS Compliance | 100% matte Sn finish, UL 94 V-0 epoxy - meets global environmental compliance without solderability trade-offs. |
| Thermal Performance | 250 °C/W RJA on FR-4 - enables accurate thermal modeling for reliability prediction in compact layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C13 | 13 V nominal, ±5% tolerance, SOD-523, 500 mW, but higher ZZT (40 Ω) and lower ESD rating (8 kV HBM). | Limited to non-handheld industrial use due to reduced ESD robustness; unsuitable for direct user-interface proximity. | Select BZX584C13 only if ESD immunity is not required and tighter ZZT is not critical. |
| MMSZ5243BT1G | 13 V nominal, ±5%, SOD-123 (2.7 × 1.6 mm), 500 mW, ZZT = 30 Ω, but larger footprint and no AEC-Q101 qualification. | Acceptable for board-level space-constrained designs where SOD-523 is unavailable, but requires PCB rework for footprint change. | Choose MMSZ5243BT1G only when SOD-523 assembly capability is limited and board real estate permits larger package. |
Compared with BZX584C13 and MMSZ5243BT1G, MM5Z13VT1G delivers superior ESD resilience (16 kV vs. 8 kV), identical ZZT performance, and smallest possible footprint - making it optimal for next-generation portable and automotive-adjacent designs demanding miniaturization and field reliability.

FAQ
What is the nominal Zener voltage and tolerance of MM5Z13VT1G?
The MM5Z13VT1G has a nominal Zener voltage of 13.25 V with a standard tolerance of ±5%, resulting in a guaranteed regulation range of 12.4 V to 14.1 V at 5 mA test current (IZT). This tolerance is confirmed in Table 3 of the onsemi datasheet revision 19 and applies directly to the MM5Z13VT1G ordering variant.
What package type and dimensions does MM5Z13VT1G use?
MM5Z13VT1G uses the SOD-523 surface-mount package (Case 502, Style 1), with exact dimensions of 1.20 mm × 0.80 mm × 0.60 mm. The cathode is marked by a polarity band on Pin 1; Pin 2 is the anode. This information is specified in the Mechanical Case Outline section and Figure on page 1 of the datasheet.
What is the maximum power dissipation and thermal derating behavior of MM5Z13VT1G?
MM5Z13VT1G has a maximum steady-state power dissipation of 500 mW at 25 °C ambient temperature on an FR-4 board with a 1 cm² copper pad. It derates linearly at 4.0 mW/°C above 25 °C, reaching zero dissipation at 150 °C - a behavior documented in the Maximum Ratings table and illustrated in Figure 1 of the datasheet.
Is MM5Z13VT1G suitable for automotive applications?
MM5Z13VT1G itself is not AEC-Q101 qualified; however, the automotive-grade variant SZMM5Z13VT1G (same electrical specs, enhanced process controls) is AEC-Q101 qualified and PPAP capable. Engineers must specify the SZ prefix for automotive use - MM5Z13VT1G is intended for commercial/industrial portable electronics.
What is the Zener impedance and reverse leakage current of MM5Z13VT1G?
MM5Z13VT1G has a maximum Zener impedance (ZZT) of 30 Ω at IZT = 5 mA and a maximum reverse leakage current (IR) of 0.1 µA at VR = 10.4 V. Both parameters are explicitly listed in the Electrical Characteristics table on page 3 of the official onsemi datasheet for MM5Z13VT1G/T5G.
