Product details
Overview
NZ9F7V5ST5G from onsemi is a 7.5 V ±3.5% tolerance Zener diode in SOD-923 package, rated for 250 mW steady-state power dissipation at 25°C with 30 Ω maximum Zener impedance at 5 mA test current and 2.5 mV/°C temperature coefficient. It provides precision voltage regulation in space-constrained portable electronics such as smartphone power rails and USB interface protection.
For engineers reviewing the NZ9F7V5ST5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 7.28–7.60 V nominal Zener voltage range, 100 pF capacitance at 0 V, Class 3 ESD rating (>16 kV HBM), AEC-Q101 qualification, and Pb-free SOD-923 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp voltage across load circuits. Its low 0.40 mm body height and 1.00 mm × 0.60 mm outline enable integration into ultra-thin mobile devices where board area and profile are critical constraints.
The NZ9F7V5ST5G exhibits tight 3.5% VZ tolerance, 30 Ω dynamic impedance at IZT = 5 mA, and a positive temperature coefficient of +2.5 mV/°C - enabling stable regulation over −65°C to +150°C junction temperature range without external compensation.
Key Specifications

FAQ
What is the exact Zener voltage range specified for NZ9F7V5ST5G?
The NZ9F7V5ST5G has a guaranteed Zener voltage range of 7.28 V to 7.60 V at a test current of 5 mA and ambient temperature of 25°C. This 3.5% tolerance window is verified per the onsemi datasheet Rev. 3, and applies directly to the NZ9F7V5ST5G - not inferred from adjacent variants in the family.
Is NZ9F7V5ST5G qualified for automotive applications?
Yes, the NZ9F7V5ST5G carries the SZ prefix variant designation and is explicitly AEC-Q101 qualified and PPAP capable per the official onsemi datasheet. This certification covers the NZ9F7V5ST5G itself, confirming its suitability for automotive infotainment, body control, and ADAS subsystems.
What is the maximum Zener impedance of NZ9F7V5ST5G and at what condition is it measured?
The maximum Zener impedance (ZZT) of NZ9F7V5ST5G is 30 Ω, measured at the specified test current IZT = 5 mA and ambient temperature of 25°C. This value is documented in the Electrical Characteristics table on page 3 of the official datasheet and applies exclusively to the NZ9F7V5ST5G.
Does NZ9F7V5ST5G have a defined temperature coefficient, and what is its value?
Yes, the NZ9F7V5ST5G has a specified temperature coefficient of +2.5 mV/°C at IZT = 5 mA. This positive coefficient is confirmed in the Electrical Characteristics table and reflects how its Zener voltage changes with junction temperature - a critical parameter for precision biasing in the NZ9F7V5ST5G's target applications.
What is the package type and physical size of NZ9F7V5ST5G?
The NZ9F7V5ST5G uses the SOD-923 package (Case 514AB), with exact dimensions of 1.00 mm × 0.60 mm × 0.40 mm (L × W × H). These measurements are specified in the Package Dimensions section of the official datasheet and are unique to the NZ9F7V5ST5G's mechanical form factor.
