Product details
Overview
MM5Z62VT1 from onsemi is a 62 V ±5% Zener diode in SOD−523 package, rated for 100 mW steady-state power dissipation at 25°C, with 215 Ω maximum Zener impedance at 1 mA test current and 35 pF capacitance at 0 V. It provides precision voltage regulation in space-constrained portable electronics such as smartphone power rail clamping and USB interface overvoltage protection.
For engineers reviewing the MM5Z62VT1 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal limits, ESD robustness (Class 3, >16 kV HBM), package dimensions, and real-world use cases aligned to ON Semiconductor's MM5Z2V4T1 series specifications.
Technical Context
The MM5Z62VT1 operates as a two-terminal voltage reference device, conducting in reverse breakdown to clamp transient overvoltages or stabilize bias points. Its 62 V nominal Zener voltage is specified at IZT = 1 mA, with temperature coefficient of +0.4 mV/°C and leakage current ≤0.05 μA at 43.4 V reverse voltage.
Designed for surface-mount assembly on FR-5 boards, it meets MSL 1 reflow requirements (260°C peak) and features a void-free thermosetting plastic case rated UL 94 V−0. Cathode-anode polarity is marked on the body, and mechanical dimensions are tightly controlled per CASE 502−01 (1.20 mm × 0.80 mm × 0.70 mm).

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-C62 | 62 V ±5%, 300 mW rating, SOD-323 package (1.7 mm × 1.3 mm), ZZT = 110 Ω @ 5 mA | Higher power handling but larger footprint; better for sustained overvoltage, less suitable for ultra-dense layouts | Select when higher surge energy absorption is required and PCB area permits larger SOD-323 placement |
| MMSZ5255B | 62 V ±5%, 500 mW rating, SOD-123 package (3.7 mm × 1.6 mm), ZZT = 150 Ω @ 20 mA | Three times higher power, significantly larger size, higher leakage (1 μA @ 49.6 V) | Choose for industrial power supplies needing higher PD, not for portable consumer electronics |
Compared with BZX584-C62 and MMSZ5255B, the MM5Z62VT1 offers the smallest footprint and lowest capacitance (35 pF), making it optimal for high-density, high-speed interfaces-though its 100 mW rating requires careful thermal design in sustained fault conditions.

FAQ
What is the Zener voltage tolerance of MM5Z62VT1?
The MM5Z62VT1 has a nominal Zener voltage of 62 V with a tolerance of ±5%, meaning the actual breakdown voltage falls between 58 V and 66 V when measured at IZT = 1 mA and TA = 25°C. This tolerance is confirmed in the Electrical Characteristics table on page 3 of the official datasheet (Rev. 2, July 2004). The MM5Z62VT1 maintains this specification across its qualified operating temperature range.
Does MM5Z62VT1 support automated SMT assembly?
Yes, the MM5Z62VT1 is qualified for lead-free reflow soldering with a maximum peak temperature of 260°C and meets Moisture Sensitivity Level 1 (MSL 1) requirements. Its SOD−523 package uses matte tin lead finish and void-free thermosetting plastic, enabling reliable placement and reflow in high-volume automated SMT lines without preconditioning. The MM5Z62VT1's thermal profile compliance is documented in the Mechanical Characteristics section.
What is the maximum reverse leakage current for MM5Z62VT1?
The MM5Z62VT1 exhibits a maximum reverse leakage current (IR) of 0.05 μA when biased at 43.4 V - which is 70% of its nominal Zener voltage. This value is specified at TA = 25°C and is critical for low-power bias networks. The MM5Z62VT1's ultra-low leakage supports extended battery life in always-on sensor nodes and portable devices.
How does the capacitance of MM5Z62VT1 affect high-speed signal lines?
The MM5Z62VT1 has a maximum capacitance of 35 pF at 0 V and 1 MHz, making it suitable for protecting high-speed digital interfaces like USB 2.0 without degrading signal rise/fall times or eye diagrams. This low C value minimizes loading on D+ and D− lines, preserving signal integrity up to 480 Mbps. The MM5Z62VT1's capacitance is measured per the test conditions defined in the datasheet's Electrical Characteristics table.
Is MM5Z62VT1 rated for automotive temperature ranges?
Yes, the MM5Z62VT1 is rated for junction and storage temperatures from −65°C to +150°C, covering AEC-Q101-relevant extremes including under-hood and cabin environments. While not AEC-Q101 certified out-of-box, its thermal specification supports use in automotive body control modules and infotainment power domains when validated per system-level requirements. The MM5Z62VT1's temperature coefficient of +0.4 mV/°C further ensures predictable behavior across this full range.
