Product details
Overview
NZ9F9V1T5G from onsemi is a 250 mW, 9.1 V Zener voltage regulator diode in SOD−923 package, with ±5% tolerance (8.65–9.56 V), 30 Ω max Zener impedance at 5 mA test current, and 0.5 μA max reverse leakage at 7 V. It provides precision voltage clamping for low-power protection circuits in space-constrained portable electronics.
For engineers reviewing the NZ9F9V1T5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 9.1 V nominal Zener voltage, 250 mW power rating, SOD−923 footprint compatibility, AEC−Q101 qualification (SZ-prefix variant), and Class 3 ESD robustness (>16 kV HBM).
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable reference voltage across its cathode-anode terminals under reverse bias. Its Zener breakdown mechanism delivers predictable regulation with temperature coefficient of +3.8 mV/°C and capacitance of 80 pF at 0 V and 1 MHz.
The SOD−923 package enables high-density PCB layout with 1.00 mm × 0.60 mm body outline and 0.40 mm height. Thermal resistance is 500 °C/W, supporting operation from −65 °C to +150 °C junction temperature with 2.0 mW/°C derating above 25 °C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C9V1 | Same 9.1 V nominal, but 300 mW rating and SOD-323 package (1.7 mm × 1.3 mm) | Larger footprint; higher power margin but less suitable for ultra-dense layouts | Choose for higher power headroom where board space permits |
| MMSZ5240B | 9.1 V nominal, 500 mW rating, SOD-123 package (3.7 mm × 1.6 mm), ±5% tolerance | 3× larger footprint; better thermal dissipation but incompatible with SOD−923 land pattern | Prefer when thermal management dominates over miniaturization requirements |
Compared with BZX584-C9V1 and MMSZ5240B, NZ9F9V1T5G offers the smallest footprint (1.00 mm × 0.60 mm) and lowest profile (0.40 mm) while maintaining identical 9.1 V regulation and Class 3 ESD rating-making it optimal for next-generation portable and automotive modules where PCB real estate is constrained.

FAQ
What is the Zener voltage tolerance for NZ9F9V1T5G?
The NZ9F9V1T5G has a nominal Zener voltage of 9.1 V with a tolerance of ±5%, resulting in a specified range of 8.65 V to 9.56 V at 5 mA test current and 25 °C ambient temperature. This tolerance is confirmed in the Electrical Characteristics table on page 3 of the official datasheet (Rev. 4, November 2016). The NZ9F9V1T5G maintains this specification under standard test conditions and is not rated for tighter tolerances.
Is NZ9F9V1T5G RoHS compliant and lead-free?
Yes, NZ9F9V1T5G is fully RoHS compliant, Pb-free, halogen-free, and BFR-free, with 100% matte tin lead finish. This is explicitly stated in the Specification Features section of the datasheet and verified in the Mechanical Characteristics and Ordering Information sections. The "T5G" suffix denotes the Pb-free SOD−923 packaging used for NZ9F9V1T5G.
Does NZ9F9V1T5G meet automotive qualification standards?
The base NZ9F9V1T5G part is not automotive-qualified; however, its SZ-prefix variant-SZNZ9F9V1T5G-is AEC−Q101 qualified and PPAP capable. The datasheet clearly distinguishes that only parts with the "SZ" prefix meet automotive requirements. NZ9F9V1T5G itself is intended for commercial and industrial applications unless ordered with the SZ prefix.
What is the maximum reverse leakage current for NZ9F9V1T5G?
The maximum reverse leakage current for NZ9F9V1T5G is 0.5 μA at VR = 7 V and TA = 25 °C, as specified in the Electrical Characteristics table. This value is measured under standardized test conditions and reflects the device's ability to minimize standby current in battery-sensitive designs. Leakage increases at higher temperatures or voltages outside this condition.
Can NZ9F9V1T5G be used in reflow soldering processes?
Yes, NZ9F9V1T5G is qualified for lead-free reflow soldering with a maximum peak temperature of 260 °C and meets MSL 1 (Moisture Sensitivity Level 1) requirements. The datasheet confirms this in the Mechanical Characteristics section, specifying "QUALIFIED MAX REFLOW TEMPERATURE: 260°C" and "Device Meets MSL 1 Requirements"-ensuring robust manufacturability without pre-baking.
