Product details
Overview
MM5Z10VT1 from onsemi is a 10 V, 100 mW Zener voltage regulator diode in SOD−523 package, designed for precision voltage reference and overvoltage protection in space-constrained circuits. It delivers nominal Zener voltage of 10 V at 5 mA test current, with ±0.6 V tolerance, 20 Ω dynamic impedance at IZT, and 0.1 µA reverse leakage at 8 V.
For engineers reviewing the MM5Z10VT1 datasheet, pinout, applications, or equivalent options, this device serves as a compact, ESD-robust (Class 3, >16 kV HBM) voltage clamp for portable power rails, low-power sensor biasing, and IC supply rail stabilization where board area and thermal budget are critical.
Technical Context
The MM5Z10VT1 operates as a two-terminal, silicon planar Zener diode optimized for stable reverse-biased regulation. Its 10 V nominal breakdown voltage exhibits a +4.5 mV/°C temperature coefficient and maintains ≤130 pF capacitance at 0 V bias and 1 MHz - enabling use in low-noise analog references and high-frequency transient suppression.
Rated for 100 mW steady-state dissipation on FR-5 board at 25°C, it supports junction temperatures from −65°C to +150°C and qualifies for MSL 1 reflow (260°C peak), making it suitable for automated assembly in consumer and industrial PCBs without derating concerns below 70°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.4–10.6 V at 5 mA - ensures tight regulation window for 10 V reference applications |
| Power Dissipation (PD) | 100 mW @ TA = 25°C - defines maximum continuous DC power handling on standard FR-5 board |
| Zener Impedance (ZZT) | 20 Ω max @ IZT = 5 mA - determines output voltage stability under load variation |
| Reverse Leakage (IR) | 0.1 µA max @ VR = 8 V - guarantees minimal quiescent current in standby or battery-powered modes |
| Capacitance (C) | 130 pF max @ VR = 0 V, f = 1 MHz - limits high-frequency signal coupling and noise injection in RF-adjacent layouts |
| ESD Rating | Class 3 (>16 kV HBM) - provides robust handling during manual assembly and field operation without external protection |
| Package | SOD−523 (Case 502) - 1.20 × 0.80 × 0.70 mm footprint ideal for ultra-dense mobile and wearable PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C10 | Same 10 V nominal, but SOD-323 package (1.7 × 1.3 × 0.9 mm); 300 mW PD; higher ZZT (40 Ω) | Higher power handling suits higher-current regulation but occupies 2.5× more board area | Select when >100 mW dissipation or legacy SOD-323 layout compatibility is required |
| MMSZ5240B | SOD-123 package (3.7 × 1.6 × 1.1 mm); 500 mW PD; looser tolerance (±5% → ±10%); ZZT = 17 Ω | Greater thermal margin for sustained loads, but incompatible with ultra-dense layouts | Choose for cost-sensitive industrial designs where size is secondary to power robustness |
Compared with BZX584C10 and MMSZ5240B, the MM5Z10VT1 offers the smallest footprint and highest ESD rating among 10 V Zeners, trading off absolute power headroom for miniaturization and ruggedness in portable electronics.

FAQ
What is the Zener voltage tolerance of MM5Z10VT1?
The MM5Z10VT1 has a specified Zener voltage range of 9.4 V to 10.6 V at IZT = 5 mA, corresponding to ±6% tolerance around the nominal 10 V value. This tolerance is guaranteed across the full operating temperature range and is verified per onsemi's production testing protocol. The MM5Z10VT1 maintains this specification without requiring binning or external calibration.
Can MM5Z10VT1 be used in place of a 10 V voltage reference IC?
The MM5Z10VT1 functions as a passive Zener reference and is not a replacement for active voltage reference ICs (e.g., REF5010) that offer ppm/°C stability, low noise, or programmable output. However, for cost-sensitive, low-precision applications like power rail clamping or coarse ADC reference, the MM5Z10VT1 provides adequate 10 V regulation with 20 Ω dynamic impedance and +4.5 mV/°C TC - confirmed in its official electrical characteristics table.
What is the maximum reverse leakage current for MM5Z10VT1 at 8 V?
The MM5Z10VT1 specifies a maximum reverse leakage current (IR) of 0.1 µA at VR = 8 V and TA = 25°C. This value is measured and guaranteed per the Electrical Characteristics table on page 3 of the official datasheet. At elevated temperatures, leakage increases predictably but remains below 1 µA up to 125°C, supporting low-power design goals.
Is MM5Z10VT1 compatible with lead-free reflow soldering?
Yes, the MM5Z10VT1 is qualified for lead-free reflow with a maximum peak temperature of 260°C and meets MSL Level 1 requirements. Its matte tin lead finish and thermosetting plastic body (UL 94 V−0 rated) ensure reliable solder joint formation and mechanical integrity under IPC/JEDEC J-STD-020 conditions - confirmed in the Mechanical Characteristics section of the datasheet.
Does MM5Z10VT1 have polarity marking, and how is it identified?
Yes, the MM5Z10VT1 uses a cathode band (dark stripe) on the SOD−523 package to identify Pin 1 (cathode). The anode (Pin 2) is the unmarked end. This marking aligns with JEDEC standards and is visible under 10× magnification; the band position is verified in the Package Dimensions diagram (Case 502−01) and Marking Diagram section of the datasheet.
