Product details
Overview
NZ9F2V7ST5G from onsemi is a 2.67–2.91 V, 250 mW Zener voltage regulator diode in SOD−923 package, designed for precision low-voltage regulation and ESD protection in space-constrained portable electronics. It delivers tight Zener tolerance (±5% at IZT = 5 mA), 100 Ω max dynamic impedance at test current, and −3.5 mV/°C temperature coefficient.
For engineers reviewing the NZ9F2V7ST5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 2.8 V nominal Zener voltage, 20 μA max leakage at VR = 1 V, 210 pF capacitance at 0 V/1 MHz, AEC−Q101 qualification, and SOD−923 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a two-terminal shunt voltage reference, maintaining stable reverse-biased breakdown across load variations. Its 250 mW power rating is derated linearly above 25°C (2.0 mW/°C), with thermal resistance RJA = 500 °C/W on FR-4 board.
The NZ9F2V7ST5G features Class 3 HBM ESD robustness (>16 kV), 100% matte tin lead finish, MSL 1 reflow capability up to 260°C, and Pb-free construction compliant with RoHS. Its marking "3*" identifies the 2.67–2.91 V variant within the NZ9FxxxST5G series.
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 | 2.7 V nominal, ±5% tolerance, 200 mW PD, SOD-523 package (0.8 × 0.6 mm) | Lower power rating and slightly larger footprint; lacks AEC−Q101 qualification | Select when automotive qualification is not required and board space allows 0.2 mm longer body |
| MMSZ4678T1G | 2.7 V nominal, ±5% tolerance, 500 mW PD, SOD-123 package (3.7 × 1.6 mm) | Higher power but 6× larger area; same Zener specs but no HBM >16 kV rating | Choose for higher-power clamping where PCB real estate permits and ESD robustness is secondary |
Compared with BZX584C2V7LT1G and MMSZ4678T1G, the NZ9F2V7ST5G uniquely combines AEC−Q101 qualification, Class 3 ESD rating, and the smallest industry-standard SOD−923 footprint-making it optimal for next-gen portable and automotive edge nodes where size, reliability, and ruggedness are co-constrained.

FAQ
What is the nominal Zener voltage of NZ9F2V7ST5G?
The NZ9F2V7ST5G has a nominal Zener voltage of 2.8 V, with a guaranteed range of 2.67 V to 2.91 V at test current IZT = 5 mA. This value is marked as "3*" on the device top-side and is specified per the onsemi datasheet Rev. 3. The NZ9F2V7ST5G maintains this regulation window across its operating temperature range and supports stable biasing in low-voltage analog circuits.
Is NZ9F2V7ST5G qualified for automotive use?
Yes, NZ9F2V7ST5G is AEC−Q101 qualified and PPAP capable, as confirmed in the official onsemi datasheet. The "SZ" prefix variant (SZNZ9F2V7ST5G) explicitly denotes automotive-grade screening and process controls. The NZ9F2V7ST5G shares identical electrical and mechanical specifications with its SZ counterpart and is approved for use in cabin controllers, ADAS sensors, and infotainment systems meeting automotive reliability requirements.
What is the maximum operating temperature for NZ9F2V7ST5G?
The NZ9F2V7ST5G has a junction and storage temperature range of −65°C to +150°C. Its thermal resistance RJA is 500 °C/W on FR-4 board, and power dissipation must be derated linearly above 25°C at 2.0 mW/°C. At 100°C ambient, the NZ9F2V7ST5G supports up to 100 mW continuous operation-sufficient for most portable and automotive bias applications without active cooling.
Does NZ9F2V7ST5G have a defined forward voltage specification?
Yes, the NZ9F2V7ST5G specifies a maximum forward voltage VF of 0.9 V at forward current IF = 10 mA, consistent across the entire NZ9FxxxST5G series. This parameter is relevant when using the device in forward-conducting configurations (e.g., polarity protection) or evaluating conduction loss in dual-diode arrangements. The NZ9F2V7ST5G's low VF helps minimize insertion loss in such roles.
What packaging and reel configuration is available for NZ9F2V7ST5G?
NZ9F2V7ST5G is supplied in Pb-free SOD−923 package on tape-and-reel format, with 8,000 units per reel. The device marking "3*" appears on the top surface, and the reel complies with onsemi's BRD8011/D tape-and-reel specifications-including correct part orientation, sprocket hole pitch, and leader/trailer lengths. Aetrix Electronics stocks this standard configuration for immediate order fulfillment.
