Product details
Overview
MM5Z11VT5G 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 such as smartphone power rails and USB interface protection circuits.
For engineers reviewing the MM5Z11VT5G datasheet, pinout, applications, or equivalent options, key selection considerations include its 11 V nominal Zener voltage, 500 mW power rating, SOD-523 footprint compatibility, Class 3 ESD robustness (>16 kV HBM), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp or regulate voltage across load circuits. Its thermal resistance of 250 °C/W (Junction-to-Ambient) and derating slope of 4.0 mW/°C above 25 °C define safe operating limits on FR-4 PCBs with 1 cm² copper pad.
The MM5Z11VT5G exhibits a positive temperature coefficient of +5.4 mV/°C near nominal Zener voltage, enabling predictable drift compensation in bias networks. Its 130 pF capacitance at 0 V and 1 MHz supports stable operation in low-frequency regulation, not RF signal path applications.

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 300 mW rating and SOD-323 package (1.7 × 1.3 mm) | Larger footprint; lower power handling reduces margin in sustained overvoltage events | Select when existing layout accommodates SOD-323 and thermal budget permits 300 mW operation |
| MMSZ5240BT1G | 10 V nominal, ±5%, 500 mW, SOD-123 package (3.7 × 1.6 mm); higher ZZT (30 Ω) | 0.9 mm larger body height; 10 V vs. 11 V requires circuit recalibration | Choose only if system design allows 10 V reference and board space permits larger SOD-123 footprint |
Compared with BZX584C11LT1G and MMSZ5240BT1G, the MM5Z11VT5G delivers identical voltage accuracy in the smallest available footprint (SOD-523) with full 500 mW rating and automotive qualification-making it optimal for next-generation miniaturized and mission-critical applications.

FAQ
What is the Zener voltage tolerance of MM5Z11VT5G?
The MM5Z11VT5G has a standard ±5% Zener voltage tolerance, meaning its reverse breakdown voltage is guaranteed between 10.4 V and 11.6 V at 5 mA test current 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). The MM5Z11VT5G maintains this specification across its qualified operating temperature range.
Is MM5Z11VT5G suitable for automotive applications?
Yes, the MM5Z11VT5G is AEC-Q101 qualified and PPAP capable, making it suitable for automotive applications including body control modules, infotainment power supervisors, and HVAC sensor biasing. Its qualification covers temperature cycling, humidity testing, and mechanical shock per AEC standards. The MM5Z11VT5G also meets Class 3 ESD requirements (>16 kV HBM), critical for in-vehicle ECU interfaces.
What is the maximum power dissipation of MM5Z11VT5G at 85 °C ambient?
At 85 °C ambient temperature, the MM5Z11VT5G's maximum power dissipation is 260 mW. This is calculated using its 500 mW rating at 25 °C and 4.0 mW/°C linear derating factor: 500 mW − (85 − 25) × 4.0 mW = 260 mW. This value assumes mounting on an FR-4 board with a 1 cm² copper pad, as specified in Note 1 of the Maximum Ratings table in the MM5Z11VT5G datasheet.
Does MM5Z11VT5G have a polarity marking, and how is it oriented?
Yes, the MM5Z11VT5G uses Style 1 marking per the SOD-523 mechanical drawing: Pin 1 (cathode) is identified by a visible polarity band at one end of the package, while Pin 2 (anode) is the unmarked end. This orientation is consistent across all MM5ZxxxT5G series devices and is documented in the "MARKING DIAGRAM" section of the onsemi datasheet. Correct polarity alignment is essential for proper Zener breakdown operation.
What is the junction capacitance of MM5Z11VT5G and at what conditions is it measured?
The MM5Z11VT5G has a maximum junction capacitance of 130 pF, measured at zero applied reverse voltage (VR = 0 V) and 1 MHz frequency. This parameter is listed in the Electrical Characteristics table on page 3 of the datasheet and directly impacts high-frequency noise coupling in voltage reference paths. The MM5Z11VT5G's 130 pF value supports stable performance in DC and low-frequency (<100 kHz) regulation applications.
