Product details
Overview
MM5Z62V 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 62 V at 2 mA test current, with ±5% tolerance (58–66 V), 215 Ω dynamic impedance at IZT, and 200 mW power dissipation in the ultra-compact SOD-523F package - used in voltage reference circuits for industrial sensors and portable power management.
For engineers reviewing the MM5Z62V datasheet, pinout, applications, or equivalent options, key selection criteria include its 62 V Zener voltage tolerance, 215 Ω ZZT at 2 mA, 0.7 mm height constraint, moisture sensitivity level 1 rating, and cathode band marking - all critical for space-constrained, high-reliability voltage clamping designs.
Technical Context
The MM5Z62V operates as a two-terminal, silicon planar Zener diode optimized for stable reverse-biased breakdown regulation. Its electrical behavior is defined by a specified Zener voltage (VZ) of 62 V at IZT = 2 mA, with maximum Zener impedance (ZZT) of 215 Ω under that condition and leakage current (IR) ≤ 0.05 µA at 43.4 V reverse voltage.
Thermally, it supports operation from –55 °C to +150 °C and features a junction-to-ambient thermal resistance (RJA) of 500 °C/W when mounted on FR-4 PCB minimum land pad - confirming suitability for ambient-stable, low-dissipation biasing and protection roles without active heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 58–66 V at IZT = 2 mA - defines precise clamping threshold for overvoltage protection circuits |
| Zener Impedance (ZZT) | 215 Ω max at IZT = 2 mA - indicates voltage regulation stability under small-signal load variation |
| Power Dissipation (PD) | 200 mW - sets maximum continuous DC power handling in SOD-523F footprint |
| Leakage Current (IR) | ≤ 0.05 µA at VR = 43.4 V - ensures minimal standby current in high-impedance bias networks |
| Operating Temperature | –55 °C to +150 °C - enables deployment in automotive engine control and industrial motor drive environments |
| Package Height | < 0.70 mm - allows integration into ultra-thin portable electronics and stacked PCB assemblies |
| Moisture Sensitivity | Level 1 - eliminates bake requirements prior to reflow, simplifying manufacturing flow |
Pinout & Package
The MM5Z62V is housed in the SOD-523F (JEITA SC79) 2-lead surface-mount plastic package. The cathode is marked by a visible band on the device body; lead 1 is anode, lead 2 is cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Forward conduction terminal / Reference ground node | Connected to circuit ground or lower-potential node during Zener operation |
| 2 (Cathode) | Zener breakdown terminal / Regulated output node | Connected to voltage rail requiring clamping or reference; band-marked side |
Key Features
| Feature | Design Value |
|---|---|
| Wide Zener voltage range | 2.4 V to 75 V family coverage - enables single-supplier sourcing across multiple voltage rails |
| Ultra-low profile | < 0.70 mm height - fits beneath tight mechanical shields and in multi-layer flex assemblies |
| Pb-free & RoHS compliant | Matte tin (Sn) lead finish - meets global environmental compliance without solderability trade-offs |
| Green mold compound | Halogen-free epoxy encapsulation - satisfies IPC-1752A material declaration requirements |
| Cathode band marking | Visible polarity indicator - prevents assembly errors in automated pick-and-place processes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C62 | 62 V, ±5%, 300 mW, SOD-523 package - higher power rating but same footprint | Supports higher surge energy absorption; requires verification of thermal derating above 70 °C ambient | Select BZX584C62 when peak pulse power exceeds 200 mW but board space remains constrained. |
| MMSZ5259B | 62 V, ±5%, 500 mW, SOD-123 package - larger footprint, higher PD, lower ZZT (150 Ω) | Requires PCB layout change; better regulation stability under varying load currents | Choose MMSZ5259B where long-term voltage reference stability outweighs size constraints. |
Compared with MM5Z62V, BZX584C62 offers 50% higher continuous power but identical thermal resistance and package height, while MMSZ5259B trades miniaturization for superior regulation (150 Ω vs. 215 Ω ZZT) and 2.5× power headroom - making MM5Z62V optimal for ultra-thin, cost-sensitive 200 mW-limited designs.

FAQ
What is the exact Zener voltage tolerance for MM5Z62V?
The MM5Z62V has a guaranteed Zener voltage range of 58 V to 66 V at IZT = 2 mA, corresponding to a ±5% tolerance around the nominal 62 V rating. This specification is verified per the ON Semiconductor MM5Z2V4–MM5Z75V Rev. 1.5 datasheet and applies across the full operating temperature range of –55 °C to +150 °C.
Can MM5Z62V be used in place of a 63 V Zener diode?
No - MM5Z62V is not a functional substitute for a 63 V Zener diode because its specified VZ range (58–66 V) centers at 62 V and does not guarantee 63 V operation. For 63 V regulation, select a part explicitly rated at that voltage, such as the BZX584C63 or MMSZ5260B, both of which have tighter distribution centered on 63 V.
What is the maximum reverse leakage current for MM5Z62V at 43.4 V?
The maximum reverse leakage current (IR) for MM5Z62V is 0.05 µA when subjected to 43.4 V reverse voltage (VR). This value is measured at TA = 25 °C and reflects the device's ability to maintain high-impedance blocking below its Zener knee, critical for low-power bias networks.
Is MM5Z62V compatible with lead-free reflow soldering profiles?
Yes - MM5Z62V is Pb-free and RoHS compliant, with matte tin (Sn) lead finish and moisture sensitivity level 1 rating. It is qualified for standard JEDEC J-STD-020 lead-free reflow profiles, including peak temperatures up to 260 °C, without preconditioning bake required.
Does MM5Z62V have a specified Zener impedance at currents other than 2 mA?
No - the MM5Z62V datasheet specifies Zener impedance (ZZT) only at IZT = 2 mA (215 Ω max). While ZZK is given as 500 Ω max at IZK = 0.5 mA, no ZZT values are provided for other test currents. Designers must use the 2 mA point for regulation stability analysis unless performing empirical characterization.
