Product details
Overview
NZ9F15VT5G from onsemi is a 15 V ±5% Zener diode in SOD-923 package, rated for 250 mW steady-state power dissipation, 42 Ω maximum Zener impedance at 5 mA test current, and 0.1 µA reverse leakage at 11.4 V, used for precision voltage clamping and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the NZ9F15VT5G 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 × 0.37 mm), Class 3 ESD rating (>16 kV HBM), AEC-Q101 qualification status, and thermal resistance of 500 °C/W.
Technical Context
This device operates as a two-terminal voltage reference diode with sharp reverse breakdown at nominal 15 V, specified under pulsed 5 mA test current at 25 °C ambient. Its temperature coefficient is +9.2 mV/°C, and it exhibits 70 pF capacitance at 0 V bias and 1 MHz frequency.
The SOD-923 package enables ultra-compact PCB integration with 0.40 mm body height and MSL 1 reflow compatibility up to 260 °C. It uses 100% matte tin lead finish and void-free thermosetting epoxy meeting UL 94 V-0.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.25 V to 15.75 V @ IZT = 5 mA - defines clamping threshold with ±5% tolerance |
| Power Dissipation (PD) | 250 mW @ TA = 25 °C - sets maximum continuous power handling on FR-5 board |
| Zener Impedance (ZZT) | 42 Ω max @ IZT = 5 mA - determines regulation stiffness under dynamic load changes |
| Reverse Leakage (IR) | 0.1 µA max @ VR = 11.4 V - ensures minimal standby current in high-impedance bias networks |
| Capacitance (C) | 70 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and signal integrity |
| ESD Rating | Class 3 (>16 kV) per HBM - provides robust electrostatic discharge immunity in handheld assembly and field use |
| Thermal Resistance (RJA) | 500 °C/W - defines junction-to-ambient temperature rise per watt dissipated |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C15LT1G | Same 15 V nominal Zener, but SOD-523 package (0.8 × 0.6 × 0.5 mm); 300 mW PD; 30 Ω ZZT | Higher power rating and lower impedance suit higher-current clamping; taller profile may conflict with shield clearance | Select when >250 mW surge energy absorption is required and vertical space permits 0.5 mm height |
| MMSZ5245B-TP | 15 V Zener in SOD-123 package (3.7 × 1.6 × 1.1 mm); 500 mW PD; 17 Ω ZZT; no AEC-Q101 rating | Larger footprint accommodates higher thermal mass; lacks automotive qualification and Class 3 ESD | Prefer for cost-sensitive industrial power supplies where space constraints are relaxed and qualification not mandated |
Compared with BZX584C15LT1G and MMSZ5245B-TP, NZ9F15VT5G offers the smallest PCB footprint and AEC-Q101 compliance, making it optimal for space-limited automotive and portable designs where ESD robustness and qualification are mandatory-despite its slightly higher Zener impedance.

FAQ
What is the Zener voltage tolerance of NZ9F15VT5G?
The NZ9F15VT5G has a Zener voltage tolerance of ±5%, with a specified range of 14.25 V to 15.75 V measured at 5 mA test current and 25 °C ambient temperature. This tolerance is guaranteed across the full operating temperature range and supports reliable clamping in 12–15 V systems without additional calibration. The NZ9F15VT5G datasheet confirms this specification in the Electrical Characteristics table on page 3.
Is NZ9F15VT5G qualified for automotive applications?
The base NZ9F15VT5G is not AEC-Q101 qualified; however, the SZ-prefix variant SZNZ9F15VT5G is explicitly qualified per AEC-Q101 and PPAP capable. Both share identical electrical specs and SOD-923 packaging, but only the SZ version meets automotive reliability standards. For automotive use, specify SZNZ9F15VT5G-not NZ9F15VT5G-to ensure qualification compliance.
What is the maximum operating temperature for NZ9F15VT5G?
The NZ9F15VT5G has a junction and storage temperature range of −65 °C to +150 °C, as defined in the Maximum Ratings table. Its thermal resistance is 500 °C/W, so at 250 mW dissipation, junction temperature rises 125 °C above ambient-limiting safe continuous operation to ≤25 °C ambient unless heatsinking is added. Derating begins above 25 °C per the 2.0 mW/°C curve in Figure 1.
Does NZ9F15VT5G have RoHS and halogen-free compliance?
Yes, NZ9F15VT5G is Pb-Free, Halogen-Free/BFR-Free, and fully RoHS compliant per Directive 2011/65/EU. The device uses 100% matte tin lead finish and UL 94 V-0 rated epoxy molding compound. Compliance is documented in the Mechanical Characteristics section and confirmed in the "Product Environmental Compliance" notes on page 1 of the onsemi datasheet for NZ9F15VT5G.
What is the ESD rating of NZ9F15VT5G?
NZ9F15VT5G is rated Class 3 per Human Body Model (HBM) with >16 kV ESD withstand capability. This rating is verified per ANSI/ESDA/JEDEC JS-001 and applies to both terminals. The high ESD immunity makes NZ9F15VT5G suitable for direct integration into handheld and portable electronics subject to frequent handling and static discharge events.
