Product details
Overview
MM5Z9V1 from ON Semiconductor is a surface-mount Zener diode designed for precision voltage regulation and transient overvoltage protection in low-power signal conditioning and power rail stabilization circuits. It delivers a nominal Zener voltage of 9.1 V at 5 mA test current, with ±5% tolerance (8.5–9.6 V), 15 Ω dynamic impedance at IZT, and 200 mW power dissipation in the ultra-compact SOD-523F package.
For engineers reviewing the MM5Z9V1 datasheet, pinout, applications, or equivalent options, this device is selected for space-constrained designs requiring stable reference voltage generation, ESD clamp protection, and low-leakage voltage threshold detection in portable electronics, sensor interfaces, and industrial control I/O modules.
Technical Context
The MM5Z9V1 operates as a two-terminal, silicon planar Zener diode optimized for reverse-biased breakdown regulation. Its electrical behavior is defined by a sharp knee at 9.1 V under 5 mA DC test current, with low dynamic impedance (15 Ω) ensuring minimal output voltage variation under load changes.
It exhibits leakage current ≤0.2 µA at 7 V reverse bias and supports full operational functionality across –55 °C to +150 °C, enabling use in automotive under-hood and industrial ambient environments without derating.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C9V1 | Same 9.1 V nominal Zener voltage but in SOD-323 package (1.7 × 1.3 mm); 200 mW rating; higher ZZT (20 Ω) | Larger footprint requires PCB redesign; higher impedance reduces regulation precision under varying load | Select only if SOD-323 is already standardized in design and tighter ZZT is not required |
| MMSZ5240B | 9.1 V Zener in SOD-123 package (3.7 × 1.6 mm); 500 mW rating; ZZT = 15 Ω; leakage 0.1 µA @ 7.2 V | 3× larger footprint and 2.5× higher power rating-over-specified for space-constrained low-power roles | Prefer where higher surge energy handling is needed, but avoid if board area is constrained |
Compared with BZX584-C9V1 and MMSZ5240B, the MM5Z9V1 uniquely balances ultra-miniature size, low leakage, and tight regulation in a single-source-qualified SOD-523F package-making it optimal for next-generation compact, battery-sensitive designs where board real estate and quiescent current are critical.

FAQ
What is the maximum reverse leakage current for MM5Z9V1 at 7 V?
The MM5Z9V1 has a maximum reverse leakage current of 0.2 µA at 7 V reverse bias, as specified in the official ON Semiconductor datasheet Rev. 1.5. This low leakage ensures minimal impact on bias networks in precision sensor front-ends and extends battery life in always-on devices using MM5Z9V1.
Is MM5Z9V1 compatible with lead-free reflow soldering processes?
Yes, the MM5Z9V1 features a matte tin (Sn) lead finish and is rated for standard Pb-free reflow profiles including JEDEC J-STD-020. Its SOD-523F package is qualified for peak temperatures up to 260 °C, making MM5Z9V1 fully compatible with modern lead-free assembly lines without solderability degradation.
Does MM5Z9V1 meet RoHS and REACH requirements?
Yes, the MM5Z9V1 is Pb-free and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The green mold compound is halogen-free per IEC 61249-2-21, and all materials declarations are documented in ON Semiconductor's official compliance reports for MM5Z9V1.
What is the thermal resistance junction-to-ambient for MM5Z9V1?
The MM5Z9V1 has a thermal resistance (RJA) of 500 °C/W when mounted on a standard FR-4 PCB with minimum land pad, as measured per JEDEC JESD51-3. This value reflects its ultra-low thermal mass in the SOD-523F package and informs safe continuous power derating above 25 °C ambient.
Can MM5Z9V1 be used as a substitute for MM5Z9V1B or MM5Z9V1T1G?
No-MM5Z9V1 is the base part number per ON Semiconductor's ordering nomenclature. MM5Z9V1B and MM5Z9V1T1G are tape-and-reel packaging variants (e.g., different reel sizes or orientation), not electrically distinct versions. The MM5Z9V1 electrical specifications remain identical across these suffixes; only packaging and logistics differ.
