Product details
Overview
NZ9F4V3T5G from onsemi is a 4.3 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 5 μA reverse leakage current at 3.4 V. It provides precision voltage clamping in space-constrained portable electronics.
For engineers reviewing the NZ9F4V3T5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 4.09–4.52 V Zener range, 16 kV HBM ESD rating, SOD−923 footprint (1.00 mm × 0.60 mm), low 0.40 mm height, and AEC−Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a two-terminal shunt voltage reference, maintaining stable regulation by conducting reverse current above its specified Zener breakdown threshold. Its thermal resistance of 500°C/W and derating slope of 2.0 mW/°C above 25°C define safe operating limits under varying ambient conditions.
The NZ9F4V3T5G exhibits a temperature coefficient of −3.5 mV/°C and 210 pF junction capacitance at 0 V, making it suitable for low-frequency stabilization and ESD-sensitive signal line protection where minimal parasitic capacitance is required.

FAQ
What is the exact Zener voltage tolerance for NZ9F4V3T5G?
The NZ9F4V3T5G has a guaranteed Zener voltage range of 4.09 V to 4.52 V at 5 mA test current, corresponding to ±5% tolerance around the nominal 4.3 V rating. This specification is verified per the onsemi datasheet Rev. 4 and applies under standard test conditions at 25°C ambient temperature. The NZ9F4V3T5G maintains this tolerance across production lots without binning.

Yes, the NZ9F4V3T5G is AEC−Q101 qualified and PPAP capable, as confirmed in the official onsemi datasheet. The "SZ" prefix variant (SZNZ9F4V3T5G) explicitly denotes automotive-grade screening and control change requirements. The NZ9F4V3T5G itself shares identical electrical and mechanical specifications and is widely accepted in automotive subsystems including camera modules and body control units.
What is the maximum operating temperature for NZ9F4V3T5G?
The NZ9F4V3T5G has a junction and storage temperature range of −65°C to +150°C, per the onsemi datasheet. Its thermal resistance (RJA) is 500°C/W, and power derating begins above 25°C at 2.0 mW/°C. At 85°C ambient, the maximum allowable power dissipation drops to 130 mW, ensuring reliable operation in under-hood automotive or high-power-density portable environments.
Does NZ9F4V3T5G have RoHS and halogen-free compliance?
Yes, the NZ9F4V3T5G is Pb−Free, halogen-free/BFR-free, and fully RoHS compliant per EU Directive 2011/65/EU. This is explicitly stated in the onsemi datasheet and verified through material declarations. The device uses 100% matte tin lead finish and UL 94 V−0 rated epoxy molding compound, meeting strict environmental and safety standards for consumer and automotive electronics.
What is the marking code for NZ9F4V3T5G on the SOD−923 package?
The NZ9F4V3T5G is marked with the code "Y" on the top surface of the SOD−923 package, as shown in the Electrical Characteristics table on page 3 of the onsemi datasheet. The marking appears adjacent to the cathode band, with "Y" indicating the 4.3 V Zener voltage variant within the NZ9F series. No date or lot codes are included in the primary device marking.
