Product details
Overview
MM5Z11VT1G from onsemi is a 11 V, ±5% tolerance Zener diode in SOD-523 package, rated for 500 mW steady-state power dissipation at 25 °C, with 20 Ω maximum Zener impedance at 5 mA test current and 0.1 µA reverse leakage at 8.0 V. It provides precision voltage regulation in space-constrained portable electronics.
For engineers reviewing the MM5Z11VT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its 11 V nominal Zener voltage, SOD-523 footprint compatibility, thermal resistance of 250 °C/W, ESD rating >16 kV HBM, and suitability for low-leakage voltage reference and overvoltage protection circuits.
Technical Context
The MM5Z11VT1G operates as a two-terminal voltage reference device, conducting in reverse breakdown to clamp or regulate voltage across a load. Its Zener voltage is specified at IZT = 5 mA with ±5% tolerance, and it maintains stable regulation down to IZK = 1 mA where dynamic impedance rises to 160 Ω.
Thermal derating follows a linear 4.0 mW/°C reduction above 25 °C ambient, supported by a junction-to-ambient thermal resistance of 250 °C/W on FR-4 board. The device exhibits a positive temperature coefficient of +5.4 mV/°C and 130 pF capacitance at 0 V bias and 1 MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C11LT1G | Same 11 V nominal, ±5% tolerance, but SOT-23 package (2.9 × 1.3 × 1.0 mm); 350 mW power rating | Larger footprint and lower power limit reduce suitability for ultra-dense layouts or higher-current clamping | Select when board space permits larger package and thermal margin is less constrained |
| MMSZ5240BT1G | 10 V nominal, ±5% tolerance, SOD-123 package (3.7 × 1.6 × 1.1 mm); 500 mW rating | 1 V lower Zener voltage requires circuit redesign; larger size limits use in sub-2 mm pitch designs | Choose only if system-level voltage thresholds align with 10 V and SOD-123 mounting is acceptable |
Compared with BZX584C11LT1G and MMSZ5240BT1G, the MM5Z11VT1G delivers identical regulation accuracy in the smallest possible footprint (1.20 × 0.80 mm), enabling direct integration into 0.4 mm pitch smartphone flex circuits where SOT-23 and SOD-123 packages cannot fit.

FAQ
What is the Zener voltage tolerance of the MM5Z11VT1G?
The MM5Z11VT1G has a standard tolerance of ±5%, meaning its reverse breakdown voltage is guaranteed between 10.4 V and 11.6 V when tested at 5 mA (IZT) and 25 °C ambient temperature. This tolerance is confirmed in the Electrical Characteristics table on page 3 of the official onsemi datasheet (Rev. 19, April 2025).
Can the MM5Z11VT1G be used in automotive applications?
The MM5Z11VT1G itself is not AEC-Q101 qualified; however, the SZMM5Z11VT1G variant is automotive-grade and PPAP-capable. For non-automotive designs, the MM5Z11VT1G remains suitable for consumer portables and industrial controls where AEC-Q101 is not mandated.
What is the maximum reverse leakage current for the MM5Z11VT1G?
The MM5Z11VT1G specifies a maximum reverse leakage current (IR) of 0.1 µA at a reverse voltage (VR) of 8.0 V and ambient temperature of 25 °C. This value is measured per the test conditions defined in the onsemi datasheet's Electrical Characteristics table.
Does the MM5Z11VT1G have a defined forward voltage specification?
Yes-the MM5Z11VT1G has a maximum forward voltage (VF) of 0.9 V at a forward current (IF) of 10 mA, as stated in the datasheet's Electrical Characteristics section. This parameter applies when the device is operated in forward conduction mode, such as during ESD event clamping on bidirectional lines.
How does thermal derating affect the MM5Z11VT1G's power handling?
The MM5Z11VT1G's power dissipation must be linearly derated by 4.0 mW per °C above 25 °C ambient, based on its 250 °C/W junction-to-ambient thermal resistance. At 85 °C ambient, its usable power drops to 260 mW-critical for reliability in sealed handheld enclosures.
