Product details
Overview
NZ9F2V4T5G from onsemi is a 2.4 V ±5% Zener voltage regulator 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 16 kV ESD rating (HBM Class 3), used for precision low-voltage clamping and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the NZ9F2V4T5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 2.28–2.52 V Zener voltage range, 1000 Ω max Zener impedance at knee current, −3.5 mV/°C temperature coefficient, RoHS-compliant Pb-free construction, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a two-terminal shunt voltage regulator, conducting in reverse breakdown to maintain stable reference voltage across load circuits. Its low 0.40 mm body height and 1.00 mm × 0.60 mm footprint enable integration into ultra-dense PCB layouts where thermal mass and board area are constrained.
The NZ9F2V4T5G exhibits defined electrical behavior under pulsed test conditions (IZT = 5 mA), with guaranteed leakage current ≤1 μA at VR = 1 V and forward voltage ≤0.9 V at IF = 10 mA. Its MSL 1 reflow rating supports standard lead-free assembly without moisture sensitivity concerns.

FAQ
What is the exact Zener voltage tolerance of NZ9F2V4T5G at 25 °C?
The NZ9F2V4T5G has a guaranteed Zener voltage range of 2.28 V minimum to 2.52 V maximum when tested at IZT = 5 mA and TA = 25 °C, corresponding to a ±5% tolerance around the nominal 2.4 V rating. This specification is verified per onsemi's published Electrical Characteristics table on page 3 of the NZ9F2V4/D datasheet.
Is NZ9F2V4T5G suitable for automotive applications?
Yes, the NZ9F2V4T5G is AEC-Q101 qualified and PPAP capable, with junction temperature range from −65 °C to +150 °C and MSL 1 reflow compatibility. The "SZ" prefix variant (SZNZ9F2V4T5G) explicitly denotes automotive-grade screening, but the NZ9F2V4T5G itself meets the same qualification requirements per onsemi documentation.
What is the maximum allowable reverse leakage current for NZ9F2V4T5G?
The NZ9F2V4T5G specifies a maximum reverse leakage current (IR) of 1 μA at VR = 1 V and TA = 25 °C. This value is confirmed in the Electrical Characteristics table on page 3 of the datasheet and reflects worst-case leakage under typical bias conditions for low-power standby operation.
Does NZ9F2V4T5G have a defined forward voltage specification?
Yes, the NZ9F2V4T5G has a maximum forward voltage (VF) of 0.9 V at IF = 10 mA, as stated in the Electrical Characteristics section of the datasheet. This parameter is relevant for applications where the device may conduct forward during power-up sequencing or fault conditions.
How does the temperature coefficient affect NZ9F2V4T5G's regulation accuracy?
The NZ9F2V4T5G has a temperature coefficient of −3.5 mV/°C, meaning its Zener voltage decreases by approximately 3.5 mV per degree Celsius rise in junction temperature. Over a −20 °C to +70 °C range, this results in a total shift of about ±31.5 mV, which must be accounted for in precision reference designs using NZ9F2V4T5G.
