Product details
Overview
NZ9F3V0T5G from onsemi is a 3.0 V ±5% Zener 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 10 µA reverse leakage at 1.0 V, used for voltage regulation and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the NZ9F3V0T5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), low-profile SOD-923 footprint (1.00 mm × 0.60 mm), AEC-Q101 qualification, 16 kV HBM ESD rating, and thermal resistance of 500°C/W.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp voltage at its nominal Zener voltage. It exhibits a negative temperature coefficient of −3.5 mV/°C and maintains stable regulation under pulse or DC bias conditions up to 250 mW.
The SOD-923 package enables high-density PCB placement with 0.40 mm body height and Pb-free matte tin lead finish. Its MSL 1 rating supports standard reflow profiles up to 260°C without preconditioning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C3V0 | Same 3.0 V nominal Zener voltage but 350 mW power rating and SOD-523 package (0.8 × 0.6 mm) | Higher power handling allows sustained clamping in higher-energy surge events; slightly larger footprint | Select BZX584-C3V0 when >250 mW surge energy absorption is required and PCB area permits 0.2 mm longer body |
| MMSZ4676T1G | 3.0 V Zener with 500 mW rating and SOD-123 package (3.7 × 1.6 mm); 30 Ω Zz at 5 mA | Lower dynamic impedance improves regulation precision but requires 6× more board area than NZ9F3V0T5G | Choose MMSZ4676T1G for high-accuracy reference designs where layout space is not constrained and <30 Ω Zz is critical |
Compared with BZX584-C3V0 and MMSZ4676T1G, NZ9F3V0T5G offers optimal balance of ultra-small footprint, automotive qualification, and sufficient regulation stability for portable electronics-making it preferred where board area is ≤1.0 mm² and AEC-Q101 compliance is mandatory.

FAQ
What is the Zener voltage tolerance of NZ9F3V0T5G?
The NZ9F3V0T5G has a Zener voltage tolerance of ±5%, specified as 2.85 V minimum to 3.15 V maximum at 5 mA test current and 25°C ambient temperature. This tolerance remains valid across the full operating junction temperature range of −65°C to +150°C, with voltage drift compensated by its −3.5 mV/°C temperature coefficient. The NZ9F3V0T5G achieves this performance in its SOD-923 package without requiring external trimming components.
Is NZ9F3V0T5G suitable for automotive applications?
Yes, NZ9F3V0T5G is AEC-Q101 qualified and PPAP capable, with the "SZ" prefix variant (SZNZ9F3V0T5G) explicitly designated for automotive use. It meets stringent reliability requirements including high-temperature operation up to +150°C junction temperature, 16 kV HBM ESD immunity, and Pb-free/halogen-free construction compliant with automotive material standards. The NZ9F3V0T5G is commonly deployed in infotainment power rails and body control module voltage supervisors.
What is the thermal resistance of NZ9F3V0T5G?
The NZ9F3V0T5G has a junction-to-ambient thermal resistance (RJA) of 500°C/W when mounted on an FR-4 board. This value assumes standard pad layout per the datasheet's recommended soldering footprint. Derating begins above 25°C ambient at 2.0 mW/°C, allowing 200 mW dissipation at 50°C ambient. The NZ9F3V0T5G's low RJA is enabled by its thermally optimized SOD-923 epoxy mold compound and direct copper pad contact.
Does NZ9F3V0T5G have a defined forward voltage specification?
Yes, NZ9F3V0T5G specifies a maximum forward voltage (VF) of 0.9 V at 10 mA forward current, consistent across all variants in the NZ9F Series. This parameter is measured under DC conditions at 25°C and confirms diode functionality for polarity verification and basic rectification checks. While primarily intended for reverse-bias Zener operation, the NZ9F3V0T5G's forward conduction behavior remains predictable and repeatable for production test validation.
What packaging format is available for NZ9F3V0T5G?
NZ9F3V0T5G is supplied in 8,000-piece tape-and-reel format per EIA-481 standard, with Pb-free (RoHS-compliant) SOD-923 packaging. The reel orientation follows standard component directionality with cathode (marked "T") facing outward, and the carrier tape complies with moisture sensitivity level (MSL) 1 requirements-no baking needed prior to reflow. Aetrix Electronics stocks NZ9F3V0T5G in full reels and cut-tape quantities for prototyping and production release.
