Product details
Overview
MM5Z8V2T1 from onsemi is a 8.2 V, 100 mW Zener diode in SOD−523 package, designed for precision voltage regulation and overvoltage protection in space-constrained circuits. It delivers ±5% nominal Zener voltage tolerance (7.7–8.7 V), 15 Ω dynamic impedance at 5 mA test current, and 0.7 µA reverse leakage at 5.0 V, enabling stable reference generation in portable power rails.
For engineers reviewing the MM5Z8V2T1 datasheet, pinout, applications, or equivalent options, key selection criteria include its low-profile 1.20 mm × 0.80 mm × 0.70 mm footprint, Class 3 ESD rating (>16 kV HBM), −65 °C to +150 °C operating range, and suitability for voltage clamping in battery-powered RF front-ends and USB interface protection.
Technical Context
The MM5Z8V2T1 operates as a two-terminal silicon Zener diode with controlled reverse breakdown behavior. Its 8.2 V nominal Zener voltage is specified at IZT = 5 mA, with temperature coefficient of +3.2 mV/°C and maximum Zener impedance of 15 Ω at IZT, ensuring predictable regulation under varying thermal and load conditions.
It features a low 0.7 µA reverse leakage current at VR = 5.0 V and 135 pF junction capacitance at 0 V bias and 1 MHz, making it suitable for high-frequency signal line protection where minimal capacitive loading is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 8.2 V at IZT = 5 mA - defines primary regulation point for stable reference or clamp voltage |
| Zener Voltage Range | 7.7 V to 8.7 V - ensures design margin for worst-case tolerance across production lots |
| Power Dissipation | 100 mW at TA = 25 °C - limits continuous current to ~12.2 mA at 8.2 V without derating |
| Zener Impedance | 15 Ω max at IZT = 5 mA - determines output voltage variation under load transients |
| Reverse Leakage | 0.7 µA max at VR = 5.0 V - minimizes standby current in always-on protection circuits |
| Junction Capacitance | 135 pF at VR = 0 V, f = 1 MHz - impacts high-frequency signal integrity in RF or data-line applications |
| ESD Rating | Class 3 (>16 kV HBM) - provides robust handling during PCB assembly and end-user operation |
Pinout & Package
SOD−523 surface-mount package: ultra-compact 1.20 mm × 0.80 mm body with 0.70 mm height; void-free thermosetting plastic case rated UL 94 V−0; matte tin lead finish; MSL 1 compliant; qualified for 260 °C reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener cathode terminal | Connected to higher-potential node; reverse-biased operation requires positive voltage applied here relative to anode |
| 2 (Anode) | Zener anode terminal | Connected to lower-potential node (e.g., ground or return path); completes reverse-bias conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOD−523 footprint | 1.20 mm × 0.80 mm × 0.70 mm - enables placement in dense mobile PCB layouts with minimal board area |
| Precision Zener voltage tolerance | ±5% (7.7–8.7 V) - supports tight voltage margining in regulated supply feedback paths |
| High ESD robustness | Class 3 (>16 kV HBM) - eliminates need for external ESD protection in handheld device interfaces |
| Stable temperature coefficient | +3.2 mV/°C - enables predictable drift compensation in temperature-sensitive reference designs |
| Low leakage at sub-Zener voltage | 0.7 µA @ 5.0 V - reduces quiescent power loss in always-on voltage monitor 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-C8V2 | Same 8.2 V nominal Zener, but SOD-323 package (1.7 mm × 1.3 mm); 200 mW power rating; 20 Ω ZZT | Larger footprint and higher power capability suit less space-constrained industrial sensors | Select when higher surge energy handling is required and board area permits larger SOD-323 layout |

FAQ
What is the maximum steady-state power dissipation of the MM5Z8V2T1?
The MM5Z8V2T1 has a maximum steady-state power dissipation of 100 mW at ambient temperature (TA) = 25 °C. This rating assumes mounting on an FR-5 board and must be derated linearly above 25 °C per the device's thermal resistance specification. Exceeding this limit risks thermal runaway and permanent degradation of the MM5Z8V2T1's Zener characteristics.
Does the MM5Z8V2T1 have a specified forward voltage drop?
Yes, the MM5Z8V2T1 specifies a maximum forward voltage (VF) of 0.9 V at forward current (IF) = 10 mA. This parameter is relevant when the device is used in forward-conducting configurations, such as polarity protection or dual-direction clamping circuits, and confirms reliable turn-on behavior below standard logic thresholds.
What is the Zener impedance of the MM5Z8V2T1 and why does it matter?
The MM5Z8V2T1 has a maximum Zener impedance (ZZT) of 15 Ω at test current IZT = 5 mA. This value quantifies how much the output voltage changes under varying load current - lower ZZT means tighter regulation. For the MM5Z8V2T1, 15 Ω ensures voltage deviation remains within ±75 mV for ±1.2 mA load shifts, critical for stable reference generation.
Can the MM5Z8V2T1 be used in high-frequency signal paths?
Yes, the MM5Z8V2T1 exhibits 135 pF junction capacitance at 0 V bias and 1 MHz, making it suitable for protecting low-speed digital lines (e.g., I²C, UART) and RF front-end bias networks. However, its capacitance may distort signals above ~10 MHz; for faster interfaces like USB 3.0 or PCIe, lower-capacitance TVS devices are recommended instead of the MM5Z8V2T1.
Is the MM5Z8V2T1 RoHS-compliant and halogen-free?
Yes, the MM5Z8V2T1 is RoHS-compliant and halogen-free per onsemi's product compliance documentation. Its void-free thermosetting plastic case meets UL 94 V−0, and the 100% matte tin lead finish satisfies JEDEC J-STD-609 Category 1 requirements for lead-free assembly compatibility and environmental safety.
