Product details
Overview
MM5Z16VT1 from onsemi is a 16.2 V nominal Zener diode in SOD−523 package, rated for 100 mW steady-state power dissipation, with 40 Ω maximum Zener impedance at 2 mA test current and 0.05 µA reverse leakage at 11.2 V, designed for precision voltage regulation and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the MM5Z16VT1 datasheet, pinout, applications, or equivalent options, this device serves as a compact, ESD-hardened (Class 3, >16 kV HBM) voltage reference and clamp in battery-powered systems where thermal budget and board area are critical constraints.
Technical Context
The MM5Z16VT1 operates as a two-terminal silicon Zener diode with sharp reverse breakdown at 16.2 V (min 15.3 V, max 17.1 V) under 2 mA test current. Its low 0.7 mm body height and 1.20 mm × 0.80 mm footprint enable integration into high-density PCBs without compromising thermal derating.
It exhibits a +10.4 mV/°C temperature coefficient and 105 pF capacitance at 0 V bias and 1 MHz, supporting stable DC regulation while limiting AC coupling effects in signal-path clamping applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.3–17.1 V @ IZT = 2 mA - defines regulated output range under nominal bias |
| Zener Impedance (ZZT) | 40 Ω max @ 2 mA - ensures minimal voltage shift under load transients |
| Power Dissipation (PD) | 100 mW @ TA = 25°C - sets maximum continuous DC power handling on FR-5 board |
| Reverse Leakage (IR) | 0.05 µA @ VR = 11.2 V - guarantees low standby current in battery-critical circuits |
| ESD Rating | Class 3 (>16 kV HBM) - provides robustness against human-handling electrostatic discharge |
| Package Dimensions | 1.20 mm × 0.80 mm × 0.70 mm - fits 0402-class footprints with reduced height for stacked assemblies |
Pinout & Package
SOD−523 surface-mount plastic package (Case 502), void-free thermosetting epoxy (UL 94 V−0), matte tin lead finish, MSL 1 compliant, qualified to 260°C reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener anode connection point | Connected to higher-potential rail; reverse-biased operation requires cathode at positive potential relative to anode |
| 2 (Anode) | Zener cathode connection point | Typically tied to ground or reference node; completes reverse-bias path for regulation/clamping function |
Key Features

FAQ
What is the maximum reverse current (IZT) specified for MM5Z16VT1?
The MM5Z16VT1 is tested at a reverse Zener test current of 2 mA, as defined in its Electrical Characteristics table. This value determines the operating point for measuring nominal Zener voltage (16.2 V) and dynamic impedance (40 Ω max). Operating above 2 mA is permissible within the 100 mW power limit, but voltage regulation performance may deviate from datasheet values.
Does MM5Z16VT1 support reflow soldering per industry standards?
Yes, the MM5Z16VT1 is qualified for lead-free reflow soldering up to 260°C peak temperature and meets Moisture Sensitivity Level 1 (MSL 1) requirements. Its SOD−523 package uses matte tin plating and UL 94 V−0 epoxy, ensuring reliable joint formation and process compatibility with standard surface-mount assembly lines.
How does the temperature coefficient of MM5Z16VT1 affect its regulation accuracy?
The MM5Z16VT1 has a specified temperature coefficient of +10.4 mV/°C, meaning its Zener voltage increases by approximately 10.4 mV per degree Celsius rise in junction temperature. For applications requiring <±1% regulation over −40°C to +85°C ambient, this drift must be factored into system-level error budgets-especially in unheated enclosures or thermally coupled layouts.
Can MM5Z16VT1 be used as a substitute for MM5Z15VT1 in existing designs?
No direct substitution is recommended without validation: MM5Z16VT1 (15.3–17.1 V) and MM5Z15VT1 (14.3–15.8 V) have non-overlapping Zener voltage ranges. Replacing one with the other will shift regulation thresholds by ~1 V, potentially causing undervoltage lockout or overvoltage stress in sensitive circuits. Verify functional impact before interchange.
What is the forward voltage drop of MM5Z16VT1 at 10 mA?
The MM5Z16VT1 specifies a maximum forward voltage (VF) of 0.9 V at 10 mA forward current, consistent with standard silicon diode behavior. This parameter is relevant only when the device is operated in forward conduction mode-for example, as a polarity protection element-not during normal Zener regulation.
