Product details
Overview
NZ9F7V5T5G from onsemi is a 7.5 V ±4.8% Zener diode in SOD−923 package, rated for 250 mW steady-state power dissipation at 25°C, with 30 Ω max Zener impedance at 5 mA test current and 0.5 μA max reverse leakage at 4 V. It provides precision voltage regulation in space-constrained portable electronics.
For engineers reviewing the NZ9F7V5T5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±4.8%), low-profile 0.40 mm height, AEC−Q101 qualification for automotive use, ESD robustness (>16 kV HBM), and RoHS-compliant matte tin lead finish.
Technical Context
This device operates as a two-terminal voltage reference by maintaining a stable reverse breakdown voltage across its anode–cathode terminals under controlled current conditions. Its thermal resistance of 500°C/W and derating slope of 2.0 mW/°C above 25°C define safe operating limits in compact PCB layouts.
The SOD−923 package supports reflow soldering up to 260°C and meets MSL 1 requirements with void-free thermosetting epoxy (UL 94 V−0). Marking "D*" identifies the NZ9F7V5T5G variant, with cathode indicated by band position per standard diode polarity convention.

FAQ
What is the Zener voltage tolerance of NZ9F7V5T5G?
The NZ9F7V5T5G has a Zener voltage range of 7.13 V to 7.88 V at 5 mA test current, corresponding to a ±4.8% tolerance about the nominal 7.5 V value. This tolerance is specified at 25°C ambient and remains stable across its −65°C to +150°C junction temperature range. The NZ9F7V5T5G datasheet confirms this range in the Electrical Characteristics table on page 3.
Is NZ9F7V5T5G qualified for automotive applications?
Yes, NZ9F7V5T5G is AEC−Q101 qualified and PPAP capable, as explicitly stated in the "Specification Features" section of the official datasheet. The "SZ" prefix variant (SZNZ9F7V5T5G) denotes automotive-grade screening, but the NZ9F7V5T5G itself shares the same qualification and is listed in the same qualified series table. NZ9F7V5T5G meets automotive reliability and stress-test requirements for under-hood and cabin electronics.
What is the maximum operating temperature for NZ9F7V5T5G?
The NZ9F7V5T5G has a junction and storage temperature range of −65°C to +150°C, per the Maximum Ratings table. Its thermal resistance is 500°C/W, and power must be derated linearly above 25°C at 2.0 mW/°C. At 100°C ambient, the maximum allowable power drops to 100 mW. These limits ensure reliable operation in automotive and industrial environments where NZ9F7V5T5G is commonly deployed.
Does NZ9F7V5T5G have RoHS and halogen-free compliance?
Yes, NZ9F7V5T5G is Pb−Free, halogen-free/BFR-free, and fully RoHS compliant, as confirmed in the "Specification Features" section of the datasheet. Its matte tin lead finish and UL 94 V−0 epoxy mold compound meet environmental directives for consumer and automotive electronics. This compliance is verified for the SOD−923 package used by NZ9F7V5T5G and applies to all units shipped with the "T5G" suffix.
What is the ESD rating of NZ9F7V5T5G?
NZ9F7V5T5G has an ESD rating of Class 3 (>16 kV) per the Human Body Model (HBM), as specified in the "Specification Features" section. This high immunity level is achieved through process-level design and packaging, enabling safe handling during manual assembly and reliable operation in electrostatic-prone environments such as handheld device manufacturing. The NZ9F7V5T5G maintains this rating across its full temperature range.
