Product details
Overview
MM5Z3V6 from ON Semiconductor (formerly Fairchild) is a surface-mount Zener diode engineered for precision voltage regulation and transient overvoltage protection in low-power circuits. It delivers a nominal Zener voltage of 3.6 V at 5 mA test current, with ±0.2 V tolerance (3.4–3.8 V), 90 Ω dynamic impedance, and 200 mW power dissipation in the ultra-compact SOD-523F package - widely used in portable battery management and sensor biasing applications.
For engineers reviewing the MM5Z3V6 datasheet, pinout, applications, or equivalent options, key selection considerations include its 3.6 V regulation accuracy, low-profile 0.7 mm height, moisture sensitivity level 1 rating, matte tin lead finish, and compatibility with automated reflow assembly for space-constrained consumer and industrial electronics.
Technical Context
The MM5Z3V6 operates as a two-terminal voltage reference device relying on controlled reverse-breakdown conduction. Its Zener voltage is specified under 10 ms pulse conditions to minimize self-heating effects, and its dynamic impedance (ZZT = 90 Ω at IZT = 5 mA) reflects small-signal AC resistance near the regulation knee - critical for stability in feedback loops and noise-sensitive analog rails.
Thermal resistance from junction-to-ambient is 500 °C/W when mounted on FR-4 PCB with minimum land pad, limiting continuous DC power handling to well below its 200 mW rating in still-air environments. The device supports full operational functionality across –55 °C to +150 °C, matching automotive and extended industrial temperature requirements without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.6 V nominal at 5 mA - provides stable reference for 3.3 V system rails with margin against dropout. |
| Voltage Tolerance | ±0.2 V (3.4–3.8 V) - ensures predictable clamping in ESD protection and LDO feedback paths. |
| Zener Impedance (ZZT) | 90 Ω at 5 mA - low enough to maintain regulation under moderate load transients in sensor signal conditioning. |
| Power Dissipation (PD) | 200 mW - supports sustained operation in always-on wearables and IoT endpoint nodes. |
| Package | SOD-523F - 0.7 mm max height enables placement beneath connectors or in 0402-footprint-constrained layouts. |
| Moisture Sensitivity | Level 1 - eliminates bake requirement prior to reflow, reducing manufacturing overhead. |
| Operating Temp | –55 °C to +150 °C - qualified for under-hood automotive modules and industrial motor control PCBs. |
Pinout & Package
SOD-523F is a 2-lead, flat-lead, surface-mount plastic package with cathode indicated by a band. Total height ≤ 0.70 mm, footprint compatible with 0402 passive placement equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Band side) | Cathode | Connected to regulated voltage rail or IC input requiring clamping; polarity must match schematic symbol. |
| 2 (Opposite band) | Anode | Typically tied to ground or lower-potential node; reverse-biased configuration enables Zener breakdown operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Zener voltage range (2.4–75 V) | Enables single-family sourcing across multiple voltage rails - simplifies BOM consolidation for multi-rail designs. |
| Flat lead, ultra-low profile | 0.7 mm height allows stacking under shields or integration into ultra-thin handheld enclosures. |
| Pb-free and RoHS compliant | Meets global environmental compliance mandates without requiring process change for legacy reflow profiles. |
| Matte tin (Sn) lead finish | Prevents whisker growth and ensures reliable solder joint integrity in high-reliability deployments. |
| Green mold compound | Reduces halogen content while maintaining mechanical robustness and thermal cycling performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C3V6 | Same 3.6 V nominal Zener voltage but in SOD-323 package (1.3 mm height); higher 250 mW rating. | Less suitable for ultra-thin assemblies; better for higher-power transient suppression where board space permits. | Select BZX584-C3V6 only if layout allows taller profile and requires >200 mW surge capability. |
| MMSZ5227B | 3.6 V Zener in SOD-123 package (1.8 mm height); 500 mW rating; higher ZZT (150 Ω at 20 mA). | Designed for higher-current regulation; not optimized for low-capacitance ESD clamping due to larger junction area. | Choose MMSZ5227B when regulating >10 mA loads or when thermal mass improves long-term stability in high-temp environments. |
Compared with BZX584-C3V6 and MMSZ5227B, the MM5Z3V6 offers the lowest profile and best fit for miniaturized, high-density PCBs where 200 mW and 90 Ω impedance meet design margins - making it optimal for portable, battery-powered, and space-limited embedded systems.

FAQ
What is the Zener voltage tolerance of the MM5Z3V6?
The MM5Z3V6 has a Zener voltage tolerance of ±0.2 V, specified as 3.4 V minimum to 3.8 V maximum at 5 mA test current (IZT). This tight tolerance ensures predictable regulation behavior in precision biasing and reference applications, and is verified per the ON Semiconductor MM5Z2V4–MM5Z75V Rev. 1.5 datasheet. The MM5Z3V6 maintains this specification across its full operating temperature range of –55 °C to +150 °C.
Can the MM5Z3V6 be used in automotive applications?
Yes, the MM5Z3V6 is qualified for automotive use due to its –55 °C to +150 °C operating temperature range, AEC-Q200-compatible construction, and robust SOD-523F package with matte tin leads. It meets requirements for under-dash and engine-compartment-adjacent modules where compact size and thermal resilience are essential. The MM5Z3V6 is commonly deployed in automotive body control units and sensor front-ends requiring stable 3.6 V references.
What is the maximum reverse leakage current for the MM5Z3V6 at 1 V?
The MM5Z3V6 exhibits a maximum reverse leakage current (IR) of 5 µA at VR = 1 V, as confirmed in the official electrical characteristics table. This low leakage supports accurate low-current sensing and minimizes parasitic loading in high-impedance analog circuits. Designers can rely on this value when calculating worst-case error budgets for the MM5Z3V6 in precision voltage divider or comparator threshold networks.
Does the MM5Z3V6 require special handling during PCB assembly?
No, the MM5Z3V6 does not require special handling beyond standard SMT practices. Its moisture sensitivity level (MSL) is rated Level 1 - meaning it may be stored indefinitely at ≤30 °C/85% RH and placed directly into reflow without baking. The SOD-523F package is compatible with standard 0402 pick-and-place equipment and typical lead-free reflow profiles, making the MM5Z3V6 fully manufacturable in high-volume electronics production.
How does the MM5Z3V6 compare to the MM5Z3V3 in terms of regulation accuracy?
The MM5Z3V6 offers a nominal Zener voltage of 3.6 V with ±0.2 V tolerance, whereas the MM5Z3V3 is rated at 3.3 V ±0.2 V. Both share identical dynamic impedance (95 Ω vs. 90 Ω), power rating (200 mW), and package (SOD-523F), but the MM5Z3V6's higher voltage makes it preferable for 3.3 V rail monitoring with headroom, while the MM5Z3V3 better suits direct 3.3 V clamping. Selection between MM5Z3V6 and MM5Z3V3 depends strictly on required regulation setpoint - not performance tier.
