Product details
Overview
NZ9F2V7T5G from onsemi is a 2.7 V ±0.135 V Zener diode in SOD−923 package, rated for 250 mW steady-state power dissipation at 25°C, with 100 Ω maximum Zener impedance at 5 mA test current and 20 µA reverse leakage at 1 V. It provides precision low-voltage regulation in space-constrained portable electronics such as smartphone power rails and USB interface protection circuits.
For engineers reviewing the NZ9F2V7T5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 2.7 V nominal Zener voltage with tight ±5% tolerance, Class 3 ESD rating (>16 kV HBM), ultra-small 1.00 mm × 0.60 mm footprint, and AEC−Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse bias above its specified Zener breakdown voltage (2.57–2.84 V) with controlled dynamic impedance. Its thermal resistance of 500°C/W and derating slope of 2.0 mW/°C define safe operating limits under ambient temperature variation.
The SOD−923 package supports reflow soldering up to 260°C (MSL 1), features 100% matte tin lead finish, and delivers 210 pF capacitance at 0 V reverse bias and 1 MHz - critical for high-frequency noise suppression in DC-DC feedback paths and I/O line clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.57 V min to 2.84 V max @ IZT = 5 mA - defines precise clamping threshold for 2.7 V rail stabilization |
| Power Dissipation (PD) | 250 mW @ TA = 25°C - sets maximum continuous power handling on FR-4 PCB without heatsinking |
| Zener Impedance (ZZT) | ≤100 Ω @ IZT = 5 mA - ensures stable regulation under small-signal load transients |

| ESD Rating (HBM) | Class 3 (>16 kV) - enables direct integration into handheld device I/O ports without external ESD protection |
| Capacitance (C) | 210 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency bypass effectiveness in RF front-end bias networks |
| Package | SOD−923 (1.00 mm × 0.60 mm × 0.40 mm) - fits 0201-class board area, enabling >2× density vs. SOD-123 |
Pinout & Package
SOD−923 is a 2-pin surface-mount package with cathode (pin 1) and anode (pin 2) terminals. Marking "E" identifies NZ9F2V7T5G; cathode indicated by band on package end.
| Pin/Terminal | Circuit Role | Design Meaning |

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 | Same 2.7 V nominal Zener, but 300 mW rating and SOD-323 package (1.7 mm × 1.3 mm) | Larger footprint; higher power margin but unsuitable for ultra-dense layouts | Select when higher surge energy handling is required and board area permits larger package |
| MMSZ4678T1G | 2.7 V Zener, 500 mW rating, SOD-123 package (3.7 mm × 1.6 mm), 30 Ω ZZT | Lower impedance and higher power, but 3.7× larger footprint and no AEC−Q101 qualification | Prefer for non-automotive industrial regulators where stability under heavy load matters more than size |
Compared with BZX584C2V7LT1G and MMSZ4678T1G, NZ9F2V7T5G offers the smallest board area and automotive qualification at the expense of lower power rating - making it optimal for space-limited, safety-conscious consumer and automotive modules where 250 mW suffices.

FAQ
What is the exact Zener voltage tolerance for NZ9F2V7T5G?
The NZ9F2V7T5G has a guaranteed Zener voltage range of 2.57 V to 2.84 V at 5 mA test current and 25°C ambient temperature, corresponding to ±5% tolerance around the nominal 2.7 V rating. This tolerance is verified per the Electrical Characteristics table on page 3 of the official datasheet (Rev. 4, November 2016). The NZ9F2V7T5G maintains this specification across its qualified operating temperature range.
Is NZ9F2V7T5G suitable for automotive applications?
Yes, NZ9F2V7T5G is AEC−Q101 qualified and PPAP capable, with the "SZ" prefix variant (SZNZ9F2V7T5G) explicitly designated for automotive use. Its construction meets automotive reliability standards including thermal cycling, humidity testing, and mechanical shock requirements. The NZ9F2V7T5G itself shares identical electrical and mechanical specs and is widely deployed in automotive camera modules and infotainment systems.
What is the maximum reverse leakage current for NZ9F2V7T5G at 1 V?
The maximum reverse leakage current for NZ9F2V7T5G is 20 µA at VR = 1 V and TA = 25°C, as specified in the Electrical Characteristics table. This low leakage supports extended battery life in always-on wearable sensors and IoT edge nodes. The NZ9F2V7T5G maintains this performance across its full storage temperature range of −65°C to +150°C.
Does NZ9F2V7T5G have a defined temperature coefficient?
Yes, NZ9F2V7T5G has a maximum temperature coefficient of −3.5 mV/°C, meaning its Zener voltage decreases by up to 3.5 mV per degree Celsius rise in junction temperature. This value is confirmed in the Electrical Characteristics table and enables predictable voltage drift modeling in thermal-aware designs. The NZ9F2V7T5G's stable tempco supports accurate reference generation in industrial temperature ranges.
What is the recommended PCB pad layout for NZ9F2V7T5G?
The recommended soldering footprint for NZ9F2V7T5G follows ON Semiconductor Application Note AND8455/D and uses a 0.80 mm × 0.60 mm land pattern with 0.36 mm solder mask opening. The SOD−923 package requires no thermal relief; copper pour should fully surround both pads for optimal heat dissipation. This layout ensures reliable reflow for the NZ9F2V7T5G while maintaining its 250 mW power rating on standard FR-4 boards.
