Product details
Overview
MM5Z2V7T5G from onsemi is a 2.7 V ±0.2 V tolerance Zener diode in SOD-523 package, rated for 500 mW steady-state power dissipation at 25 °C, with 100 Ω maximum Zener impedance at 2.4 mA test current and 20 μA reverse leakage at 1.0 V, used for precision voltage clamping in space-constrained portable electronics.
For engineers reviewing the MM5Z2V7T5G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal derating behavior, ESD robustness (Class 3, >16 kV HBM), and direct alternatives for low-voltage regulation in battery-powered systems.
Technical Context
This device operates as a two-terminal voltage reference diode with sharp reverse breakdown at nominal 2.7 V, designed for stable clamping under low-current conditions (IZT = 2.4 mA). Its negative temperature coefficient (−3.5 mV/°C) ensures predictable drift across −65 °C to +150 °C junction range.
The SOD-523 package enables high-density PCB layout with 1.20 mm × 0.80 mm footprint and 0.7 mm height, while its 250 °C/W junction-to-ambient thermal resistance governs power derating above 25 °C per Figure 1 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal, 2.5–2.9 V min/max at IZT = 2.4 mA - defines precise clamping threshold for 3 V rail protection |
| Power Dissipation (PD) | 500 mW at TA = 25 °C - sets maximum continuous clamp power on FR-4 board with 1 cm² pad |
| Zener Impedance (ZZT) | ≤100 Ω at IZT = 2.4 mA - ensures minimal voltage shift under dynamic load transients |
| Reverse Leakage (IR) | ≤20 μA at VR = 1.0 V - guarantees low standby current in always-on sensing circuits |
| ESD Rating | Class 3 (>16 kV HBM) - provides robust handling without external protection in handheld assembly lines |
| Capacitance (C) | 450 pF at VR = 0, f = 1 MHz - limits high-frequency noise coupling in RF front-end bias networks |
| Thermal Resistance (RJA) | 250 °C/W - determines required ambient margin when operating near 500 mW in sealed enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C2V7 | 2.7 V ±5%, 300 mW rating, SOD-323 package (1.7 × 1.3 mm) | Larger footprint; higher ZZT (150 Ω); lower ESD rating (Class 2) | Select when board space permits larger package and cost sensitivity outweighs ESD robustness |
| MMSZ4684T1G | 2.7 V ±5%, 500 mW, SOD-123 package (3.7 × 1.6 mm), 150 Ω ZZT | 3.8× larger area; requires different stencil aperture; no AEC-Q101 variant | Choose for legacy SOD-123 assembly lines where requalification of SOD-523 is impractical |
Compared with BZX584C2V7 and MMSZ4684T1G, MM5Z2V7T5G offers the smallest footprint, highest ESD immunity, and tightest voltage tolerance among 2.7 V Zeners in production, making it optimal for next-gen wearables and ultra-thin mobile designs where board area and reliability are critical.

FAQ
What is the exact Zener voltage tolerance for MM5Z2V7T5G at 25 °C?
The MM5Z2V7T5G has a guaranteed Zener voltage range of 2.5 V to 2.9 V at IZT = 2.4 mA and TA = 25 °C, corresponding to ±0.2 V (±7.4%) around the nominal 2.7 V value. This tolerance is confirmed in Table 3 of the onsemi datasheet revision 19 and applies strictly to the MM5Z2V7T5G variant, not the broader MM5Zxxx family.
Does MM5Z2V7T5G support automotive applications?
The standard MM5Z2V7T5G is not automotive-qualified, but its pin-identical variant SZMM5Z2V7T5G is AEC-Q101 qualified and PPAP capable. The SZ-prefix version undergoes additional stress testing including temperature cycling, humidity bias, and high-temperature operating life, making it suitable for under-hood and infotainment systems where MM5Z2V7T5G would not be approved.
What is the maximum allowable power dissipation for MM5Z2V7T5G at 60 °C ambient?
At 60 °C ambient, MM5Z2V7T5G must be derated linearly from its 500 mW rating at 25 °C using the 4.0 mW/°C derating factor. This yields 500 mW − (60 − 25) × 4.0 mW = 360 mW maximum continuous dissipation. Exceeding this risks thermal runaway due to the device's 250 °C/W RJA.
How is polarity identified on the MM5Z2V7T5G SOD-523 package?
MM5Z2V7T5G uses Style 1 marking: a visible cathode band (dark stripe) on the SOD-523 body identifies Pin 1 as cathode. The unmarked end is the anode (Pin 2). This matches the generic marking diagram on page 5 of the datasheet and is consistent across all MM5ZxxxT5G variants.
Can MM5Z2V7T5G replace MM5Z2V4T5G in a 2.4 V reference circuit?
No - MM5Z2V7T5G is not a functional replacement for MM5Z2V4T5G because its nominal Zener voltage is 2.7 V versus 2.4 V, with non-overlapping tolerance ranges (2.5–2.9 V vs. 2.2–2.6 V). Substituting MM5Z2V7T5G would raise the clamping threshold by 300 mV, potentially violating downstream IC absolute maximum ratings or altering bias point accuracy.
