Product details
Overview
MM5Z11VT1 from onsemi is a 11 V, 100 mW surface-mount Zener diode in SOD-523 package, with nominal Zener voltage 11.0 V at 5 mA test current, maximum Zener impedance 20 Ω at IZT, and reverse leakage current ≤0.1 µA at 8.0 V. It provides precision voltage regulation and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the MM5Z11VT1 datasheet, pinout, applications, or equivalent options, key selection criteria include its 11.0 V nominal Zener voltage, ±0.6 V tolerance (10.4–11.6 V), 20 Ω dynamic impedance at 5 mA, −65 °C to +150 °C operating temperature range, and Class 3 ESD rating (>16 kV HBM).
Technical Context
The MM5Z11VT1 operates as a two-terminal voltage reference device, conducting in reverse breakdown to clamp voltage across load circuits. Its Zener mechanism delivers stable regulation under varying load currents within its 100 mW power limit and specified thermal derating curve.
Designed for low-power signal-level regulation, it features low capacitance (130 pF at 0 V, 1 MHz), minimal forward voltage (≤0.9 V at 10 mA), and a positive temperature coefficient of +5.4 mV/°C - enabling predictable drift behavior in temperature-sensitive bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.4–11.6 V at 5 mA - defines clamping threshold with ±5.5% tolerance for reliable overvoltage protection |
| Power Dissipation (PD) | 100 mW at 25 °C - sets maximum continuous power handling before thermal derating begins |
| Zener Impedance (ZZT) | 20 Ω at 5 mA - determines regulation stiffness and output voltage variation under load transients |
| Reverse Leakage (IR) | ≤0.1 µA at 8.0 V - ensures negligible standby current in high-impedance bias or sensing nodes |
| ESD Rating | Class 3 (>16 kV HBM) - supports robust handling in automated assembly and end-user portable environments |
| Capacitance (C) | 130 pF at 0 V, 1 MHz - impacts high-frequency noise filtering capability and signal integrity in RF-adjacent circuits |
| Package Dimensions | 1.20 × 0.80 × 0.70 mm - enables placement on ultra-dense PCBs where board area is constrained |
Pinout & Package
SOD-523 package: ultra-compact surface-mount plastic case (Case 502), 2-terminal configuration, cathode marked with band. Mounting position unrestricted; qualified for 260 °C reflow per J-STD-020 MSL 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (Anode) | Reference/ground return path | Tied to circuit common or lower-potential node; completes Zener conduction path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOD-523 footprint | Enables integration into 0.5 mm pitch layouts and thin-profile handheld devices without height interference |
| High ESD immunity | Withstands >16 kV human-body-model discharge, reducing need for external transient suppressors in consumer interfaces |
| Precision Zener voltage tolerance | ±5.5% (10.4–11.6 V) supports tight supply margining in 12 V system monitoring and LDO feedback paths |
| Stable temperature coefficient | +5.4 mV/°C allows predictable drift compensation in temperature-critical reference dividers |
| Low leakage at sub-Zener voltage | 0.1 µA max at 8.0 V ensures minimal loading on high-impedance sensor outputs or microcontroller wake-up circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C11 | Same 11 V nominal Zener, but SOD-323 package (1.7 × 1.3 mm); 200 mW power rating; higher leakage (≤1 µA @ 8.8 V) | Less space-constrained designs where higher power margin is needed; not suitable for same PCB footprint | Select when thermal headroom >100 mW is required and board area permits larger SOD-323 layout |
| MMSZ5242BT1G | 11.4 V nominal Zener, SOD-123 package (3.7 × 1.6 mm); 500 mW rating; 30 Ω ZZT; 0.1 µA leakage @ 9.1 V | Higher-power industrial regulators; incompatible footprint and higher Zener impedance reduces regulation accuracy | Choose only if mechanical mounting constraints allow SOD-123 and system requires >100 mW clamping energy |
Compared with BZX584-C11 and MMSZ5242BT1G, the MM5Z11VT1 offers the smallest PCB footprint and lowest profile among 11 V Zeners, making it optimal for ultra-thin portable designs where 100 mW regulation suffices and layout density is prioritized over power headroom.

FAQ
What is the Zener voltage tolerance of the MM5Z11VT1?
The MM5Z11VT1 has a guaranteed Zener voltage range of 10.4 V to 11.6 V at 5 mA test current, corresponding to ±5.5% tolerance around the nominal 11.0 V value. This specification is verified per onsemi's MM5Z2V4T1 Series datasheet Rev. 2, page 3, and applies under standard ambient conditions (TA = 25 °C). The MM5Z11VT1 maintains this tolerance across its qualified operating temperature range.
Can the MM5Z11VT1 be used in place of a 12 V Zener diode?
No - the MM5Z11VT1 is rated for 11.0 V nominal Zener voltage with a maximum of 11.6 V, making it unsuitable as a direct replacement for a true 12 V Zener such as MM5Z12VT1 (11.4–12.7 V). Using MM5Z11VT1 where 12 V clamping is required risks insufficient overvoltage protection; always verify system margin requirements against the MM5Z11VT1's actual 10.4–11.6 V range.
What is the maximum operating temperature for the MM5Z11VT1?
The MM5Z11VT1 supports a junction and storage temperature range of −65 °C to +150 °C, as specified in the Absolute Maximum Ratings table (page 2 of the datasheet). Its SOD-523 package meets MSL 1 and is qualified for reflow up to 260 °C, ensuring reliability in both extended-temperature industrial deployments and standard automated assembly processes involving the MM5Z11VT1.
Does the MM5Z11VT1 have polarity markings, and how is it oriented on PCB?
Yes - the MM5Z11VT1 uses a cathode band marking on the SOD-523 package body to identify Pin 1 (cathode). Per the mechanical drawing (page 4), the band aligns with the cathode terminal, which must connect to the higher-potential node in reverse-bias regulation. Correct orientation is essential: reversing the MM5Z11VT1 results in forward conduction (~0.9 V drop) instead of Zener clamping.
How does the temperature coefficient affect the MM5Z11VT1's performance?
The MM5Z11VT1 exhibits a positive temperature coefficient of +5.4 mV/°C, meaning its Zener voltage increases linearly with rising junction temperature. For example, a 50 °C rise above 25 °C adds ~270 mV to the nominal 11.0 V, shifting regulation to ~11.27 V. This behavior is documented in the Electrical Characteristics table (page 3) and must be factored into thermal design when using the MM5Z11VT1 in unregulated ambient environments.
