Product details
Overview
NZ9F10VST5G from onsemi is a 10 V ±4.5% Zener diode in SOD-923 package, rated for 250 mW steady-state power dissipation, with 30 Ω maximum Zener impedance at 5 mA test current and 7 μA maximum reverse leakage at 8 V. It provides precision voltage regulation in space-constrained portable electronics such as smartphone power rails and USB interface protection circuits.
For engineers reviewing the NZ9F10VST5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 10 V nominal Zener voltage, tight 4.5% tolerance, 16 kV HBM ESD rating, SOD-923 footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a two-terminal voltage reference and overvoltage clamp, leveraging silicon PN junction Zener breakdown at reverse bias. Its thermal resistance of 500 °C/W and derating curve (2.0 mW/°C above 25 °C) define safe operating limits on FR-5 PCBs.
The NZ9F10VST5G exhibits a positive temperature coefficient of +4.5 mV/°C at 5 mA, enabling predictable drift compensation in stable reference designs. Its low 0.40 mm body height and 1.00 mm × 0.60 mm outline support ultra-dense PCB layouts where board area is constrained.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C10LT1G | Same 10 V nominal Zener voltage but ±5% tolerance; 350 mW rating in SOD-523; 50 Ω ZZT | Higher power handling but larger 1.2 mm × 0.8 mm footprint; less suitable for ultra-thin mobile designs | Select when higher surge capability is needed and board area permits SOD-523 |
| MMSZ4689T1G | 10 V nominal with ±5% tolerance; 500 mW rating in SOD-123; 15 Ω ZZT; no AEC-Q101 qualification | Lower impedance improves regulation accuracy but lacks automotive qualification and has 2× height (0.9 mm) | Select for cost-sensitive industrial applications where AEC-Q101 is not required |

FAQ
What is the Zener voltage tolerance of NZ9F10VST5G?
The NZ9F10VST5G has a Zener voltage range of 9.77 V to 10.21 V at 5 mA test current, corresponding to a ±4.5% tolerance around the nominal 10 V rating. This tight tolerance is specified in the Electrical Characteristics table on page 3 of the onsemi datasheet and ensures consistent regulation performance across production lots without post-manufacture sorting.
Is NZ9F10VST5G qualified for automotive use?
Yes, NZ9F10VST5G is AEC-Q101 qualified and PPAP capable, as confirmed in the datasheet's Specification Features section. The "SZ" prefix variant (SZNZ9F10VST5G) explicitly denotes automotive-grade screening, but the NZ9F10VST5G itself shares the same qualification status and is approved for use in automotive infotainment, body control, and sensor modules.
What is the maximum reverse leakage current for NZ9F10VST5G?
The maximum reverse leakage current for NZ9F10VST5G is 0.1 μA at 8 V reverse voltage and 25 °C, per the Electrical Characteristics table on page 3 of the onsemi datasheet. This ultra-low leakage supports extended battery life in always-on sensor nodes and low-power IoT applications where standby current must remain below 100 nA.
Does NZ9F10VST5G have an ESD rating, and if so, what is it?
Yes, NZ9F10VST5G has an ESD rating of Class 3 (>16 kV) per the Human Body Model (HBM), as stated in the Specification Features section of the datasheet. This high ESD robustness eliminates the need for additional discrete ESD protection components in interfaces such as USB, audio jacks, and push-button circuits.
What is the thermal derating behavior of NZ9F10VST5G above 25 °C?
NZ9F10VST5G derates linearly at 2.0 mW/°C above 25 °C ambient temperature, with a thermal resistance of 500 °C/W from junction to ambient on FR-5 board. This means its maximum allowable power drops to 200 mW at 50 °C and 100 mW at 100 °C, ensuring safe operation within its −65 °C to +150 °C junction temperature range.
