Product details
Overview
MM5Z8V2 from ON Semiconductor (formerly Fairchild) is a surface-mount Zener diode designed for precision voltage regulation and overvoltage protection in low-power circuits. It delivers a nominal Zener voltage of 8.2 V at 5 mA test current, with ±5% tolerance (7.7–8.7 V), 200 mW power dissipation, and low dynamic impedance of 15 Ω at IZT, suitable for voltage reference and ESD clamp applications in portable electronics.
For engineers reviewing the MM5Z8V2 datasheet, pinout, applications, or equivalent options, this device is selected for compact, high-reliability DC biasing, analog signal conditioning, and transient suppression where tight voltage tolerance, low profile (<0.70 mm height), and moisture sensitivity level 1 handling are required.
Technical Context
The MM5Z8V2 operates as a two-terminal silicon Zener diode with reverse-biased breakdown behavior. Its electrical characteristics are specified under pulse test conditions (10 ms) to minimize self-heating, and its Zener impedance (ZZT) is measured with 10% RMS AC current superimposed on DC IZT.
It features a cathode-indicating band and uses a green mold compound in the SOD-523F package. Thermal resistance from junction-to-ambient is 500 °C/W when mounted on FR-4 PCB with minimum land pad, defining its derating envelope across the full –55 °C to +150 °C operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.7–8.7 V at 5 mA - defines stable regulation window for reference or clamping |
| Power Dissipation (PD) | 200 mW - limits continuous DC current to ~24 mA at 8.2 V without heatsinking |
| Zener Impedance (ZZT) | 15 Ω at IZT = 5 mA - ensures minimal output voltage variation under load changes |
| Reverse Leakage (IR) | 0.7 µA max at VR = 5 V - guarantees low standby current in bias networks |
| Package | SOD-523F - 0.7 mm height, JEITA SC79 footprint, compatible with high-density reflow assembly |
| Moisture Sensitivity | Level 1 - no bake requirement prior to SMT reflow, simplifying manufacturing flow |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C8V2 | Same 8.2 V nominal VZ, but ±2% tolerance and 300 mW PD; SOD-523 package (not SOD-523F) | Higher precision and power rating suit tighter-regulation or higher-current biasing needs | Select BZX584-C8V2 when ±2% tolerance or >200 mW headroom is required; verify SOD-523 vs. SOD-523F land pattern compatibility |
| 1SMA5919BT3G | 8.2 V nominal VZ, ±5% tolerance, but DO-214AC (SMA) package and 1.5 W PD | Larger package supports higher surge energy handling in power supply protection | Choose 1SMA5919BT3G for high-energy transient suppression where board space permits larger footprint |
Compared with MM5Z8V2, BZX584-C8V2 offers tighter voltage tolerance and higher power in a near-identical footprint, while 1SMA5919BT3G trades miniaturization for robustness-making MM5Z8V2 optimal for space-constrained, low-power regulation where 200 mW and ±5% meet system requirements.

FAQ
What is the Zener voltage tolerance of MM5Z8V2?
The MM5Z8V2 has a Zener voltage tolerance of ±5%, with a specified range of 7.7 V to 8.7 V at 5 mA test current (IZT). This tolerance is confirmed in the official ON Semiconductor datasheet Rev. 1.5 and applies across the full operating temperature range of –55 °C to +150 °C. The MM5Z8V2 achieves this stability using silicon process controls optimized for low-voltage Zener breakdown consistency.
Can MM5Z8V2 be used in automotive under-hood applications?
Yes, MM5Z8V2 is rated for an operating temperature range of –55 °C to +150 °C and is qualified per AEC-Q200 stress test guidelines for passive components. Its SOD-523F package, matte tin finish, and stable Zener characteristics make MM5Z8V2 suitable for engine control unit (ECU) sensor biasing and power rail clamping where ambient temperatures exceed 125 °C.
What is the maximum reverse leakage current for MM5Z8V2 at 5 V?
The maximum reverse leakage current (IR) for MM5Z8V2 is 0.7 µA at VR = 5 V, as specified in the Electrical Characteristics table. This low leakage ensures minimal current draw in always-on monitoring circuits and preserves battery life in portable MM5Z8V2-based voltage references.
Is MM5Z8V2 RoHS compliant and lead-free?
Yes, MM5Z8V2 is Pb-free and RoHS compliant, with a matte tin (Sn) lead finish. This is explicitly stated in the "Features" section of the ON Semiconductor datasheet and verified through material declarations. The MM5Z8V2 meets EU RoHS Directive 2011/65/EU and related global environmental standards without compromising solderability or reliability.
How does the SOD-523F package differ from standard SOD-523?
The SOD-523F package used by MM5Z8V2 is a flattened variant of SOD-523 with reduced height (≤0.70 mm vs. typical 0.9 mm), optimized for ultra-thin assemblies. While both share JEITA SC79 outline and 2-lead configuration, SOD-523F requires adjusted stencil aperture and reflow profile due to lower thermal mass. MM5Z8V2's SOD-523F footprint is not interchangeable with standard SOD-523 without layout verification.
