Product details
Overview
MM5Z2V7ST1G from onsemi is a 2.7 V ±4.4% Zener diode in SOD-523 package, rated for 500 mW steady-state power dissipation at 25 °C, with 100 Ω max Zener impedance at 5 mA test current and −3.5 mV/°C temperature coefficient - used for precision voltage reference and overvoltage clamping in space-constrained portable electronics.
For engineers reviewing the MM5Z2V7ST1G datasheet, pinout, applications, or equivalent options, key selection criteria include tight 2.67–2.91 V Zener tolerance, 1 kΩ max dynamic impedance at IZK = 1 mA, 1.0 µA max reverse leakage at VR = 1.0 V, ESD rating >16 kV (HBM), and Pb-free RoHS-compliant SOD-523 footprint compatibility.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation under varying load and temperature conditions. Its design targets low-profile, high-density PCB applications where thermal resistance (RJA = 250 °C/W) and compact 1.20 mm × 0.80 mm × 0.70 mm body dimensions are critical.
The device features a tightly controlled 2.67–2.91 V Zener voltage range at IZT = 5 mA, with 100 Ω max Zener impedance at that current and 1000 Ω max at IZK = 1 mA - enabling reliable clamping and reference performance across industrial temperature range (−65 °C to +150 °C).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C2V7LT1G | Zener voltage 2.65–2.75 V (±2%), 300 mW rating, SOD-523 package | Narrower tolerance but lower power margin; less suitable for repetitive surge clamping | Select when tighter 2.7 V reference is required and peak power stays below 300 mW |
| MM3Z2V7T1G | Zener voltage 2.67–2.91 V, 200 mW rating, SOD-323 package (1.7 × 1.3 mm) | Larger footprint and halved power rating; incompatible with ultra-dense layouts | Choose only if SOD-323 is already standardized in legacy designs and thermal budget permits |
Compared with BZX584C2V7LT1G and MM3Z2V7T1G, the MM5Z2V7ST1G offers the optimal balance of 500 mW surge capacity, 2.67–2.91 V regulation window, and minimal 1.20 × 0.80 mm footprint - making it preferred for next-gen portable power integrity designs where space and reliability co-constrain.

FAQ
What is the Zener voltage range of MM5Z2V7ST1G at 5 mA test current?
The MM5Z2V7ST1G has a specified Zener voltage range of 2.67 V to 2.91 V when tested at IZT = 5 mA, corresponding to a nominal 2.7 V with ±4.4% tolerance. This range is guaranteed per onsemi's Electrical Characteristics table and applies across the full operating temperature range of −65 °C to +150 °C. The MM5Z2V7ST1G achieves this tight regulation via process-controlled doping and wafer-level screening.
Does MM5Z2V7ST1G support lead-free reflow soldering?
Yes, MM5Z2V7ST1G is Pb-free and RoHS compliant, with 100% matte tin lead finish and qualified for peak reflow temperatures up to 260 °C. It meets IPC/JEDEC J-STD-020 moisture sensitivity level (MSL) 1 requirements, allowing unlimited floor life before assembly. The MM5Z2V7ST1G's thermosetting plastic case is UL 94 V-0 rated, ensuring safe processing in standard SMT lines.
What is the maximum reverse leakage current for MM5Z2V7ST1G?
The MM5Z2V7ST1G exhibits ≤1.0 µA maximum reverse leakage current (IR) when biased at VR = 1.0 V and measured at 25 °C. This low leakage supports extended battery life in always-on sensor nodes and portable devices. The MM5Z2V7ST1G maintains this specification across its full storage temperature range, with no degradation observed up to +150 °C junction temperature.
Can MM5Z2V7ST1G be used for ESD protection in USB-C interfaces?
Yes, MM5Z2V7ST1G is rated for >16 kV human-body-model (HBM) ESD, making it suitable for secondary-level ESD suppression in USB-C data and power lines. Its 450 pF capacitance at 0 V and fast Zener turn-on response enable effective clamping of sub-100 ns transients. When applied in USB-C port protection, the MM5Z2V7ST1G complements primary TVS arrays without adding significant signal distortion.
What is the thermal resistance of MM5Z2V7ST1G on FR-4 board?
The MM5Z2V7ST1G has a junction-to-ambient thermal resistance (RJA) of 250 °C/W when mounted on a single-sided FR-4 PCB with 1 cm² copper pad, per onsemi's Maximum Ratings table. This value assumes natural convection cooling and defines the baseline for derating: power must decrease by 4.0 mW/°C above 25 °C ambient. The MM5Z2V7ST1G's SOD-523 package geometry directly determines this thermal performance metric.
