Product details
Overview
MM5Z2V7T1 from onsemi is a 2.7 V ±0.2 V, 100 mW Zener diode in SOD−523 package, designed for precision voltage regulation and overvoltage protection in space-constrained portable electronics such as cellular handsets and high-density PCBs.
For engineers reviewing the MM5Z2V7T1 datasheet, pinout, applications, or equivalent options, key selection criteria include its 2.5–2.9 V Zener range at 5 mA, 100 Ω max Zener impedance at IZT, 20 µA max leakage at 1.0 V reverse bias, −3.5 mV/°C tempco, and Class 3 ESD rating (>16 kV HBM).
Technical Context
The MM5Z2V7T1 operates as a two-terminal shunt regulator, maintaining stable reference voltage under reverse-biased conditions with nominal test current of 5 mA. Its low 0.7 mm height and 1.20 mm × 0.80 mm footprint enable integration into ultra-compact layouts without thermal derating up to +150°C junction temperature.
It exhibits a negative temperature coefficient (−3.5 mV/°C) and low 450 pF capacitance at 0 V, making it suitable for low-noise biasing and transient suppression where minimal parasitic loading is critical-especially in RF front-end power rails and analog sensor supply lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.5 V min / 2.7 V nom / 2.9 V max @ IZT = 5 mA - defines tight regulation window for low-voltage logic rail clamping |
| Power Dissipation (PD) | 100 mW @ TA = 25°C - sets maximum continuous power handling on FR-5 board without heatsinking |
| Zener Impedance (ZZT) | ≤100 Ω @ IZT = 5 mA - ensures minimal voltage deviation under dynamic load transients |
| Reverse Leakage (IR) | ≤20 µA @ VR = 1.0 V - guarantees negligible standby current in battery-powered systems |
| ESD Rating | Class 3 (>16 kV) per HBM - provides robust handling during automated assembly and end-user operation |
| Capacitance (C) | 450 pF @ VR = 0 V, f = 1 MHz - limits signal coupling in high-frequency analog paths |
| Tempco (dVZ/dT) | −3.5 mV/°C - enables predictable drift compensation in temperature-sensitive references |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the Zener voltage tolerance of MM5Z2V7T1 at 5 mA test current?
The MM5Z2V7T1 has a guaranteed Zener voltage range of 2.5 V minimum to 2.9 V maximum at IZT = 5 mA and TA = 25°C, with 2.7 V as the nominal value. This ±0.2 V tolerance supports tight regulation in low-voltage digital and analog circuits where supply margins are narrow.
Can MM5Z2V7T1 be used in place of MM5Z2V4T1 in a 2.4 V reference design?
No-MM5Z2V7T1 is not a drop-in replacement for MM5Z2V4T1 due to its higher nominal Zener voltage (2.7 V vs. 2.4 V) and different voltage range (2.5–2.9 V vs. 2.2–2.6 V). Using MM5Z2V7T1 would shift the regulated voltage upward by ~0.3 V, potentially violating downstream IC input specifications.
What is the maximum reverse leakage current for MM5Z2V7T1 at 1.0 V bias?
The MM5Z2V7T1 specifies a maximum reverse leakage current of 20 µA at VR = 1.0 V and TA = 25°C. This low leakage ensures minimal quiescent current draw in battery-critical applications like wearables and wireless sensors.
Does MM5Z2V7T1 meet JEDEC MSL level requirements for surface-mount assembly?
Yes-the MM5Z2V7T1 meets JEDEC MSL Level 1 requirements and is qualified for peak reflow temperatures up to 260°C. Its void-free thermoset epoxy case and matte tin lead finish ensure reliable solder joint formation without popcorn cracking or delamination.
How does the temperature coefficient affect MM5Z2V7T1's performance across −40°C to +85°C?
With a specified temperature coefficient of −3.5 mV/°C, the MM5Z2V7T1's Zener voltage decreases linearly with rising temperature. Over −40°C to +85°C, this results in a total drift of approximately ±43.8 mV from nominal 2.7 V-well within typical 2.5–2.9 V tolerance band and suitable for non-precision biasing.
