Product details
Overview
NZ9F16VT5G from onsemi is a 16 V ±5% Zener diode in SOD-923 package, rated for 250 mW steady-state power dissipation, 5 mA test current, and 50 Ω maximum Zener impedance at IZT. It provides precision voltage regulation and ESD protection (Class 3, >16 kV HBM) in space-constrained portable electronics.
For engineers reviewing the NZ9F16VT5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 15.2–16.8 V Zener voltage range, low 0.40 mm height, RoHS-compliant matte tin finish, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This discrete Zener diode operates in reverse-bias breakdown mode to clamp voltage transients and stabilize reference nodes. Its thermal resistance of 500 °C/W and derating curve (2.0 mW/°C above 25 °C) define safe operating limits on FR-5 PCBs.
The device features low leakage (<0.1 µA at 12 V), tight voltage tolerance (±5%), and temperature coefficient of +10.4 mV/°C - enabling stable regulation across −65 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.2 V min to 16.8 V max @ 5 mA - ensures precise clamping within 5% tolerance for 16 V nominal rail protection |
| Power Dissipation (PD) | 250 mW @ 25 °C - supports continuous regulation in ultra-low-power portable circuits without heatsinking |
| Zener Impedance (ZZT) | 50 Ω max @ 5 mA - maintains stable output voltage under dynamic load changes in feedback or reference paths |
| Reverse Leakage (IR) | 0.1 µA max @ 12 V - minimizes quiescent current loss in battery-powered systems |
| ESD Rating | Class 3 (>16 kV HBM) - provides robust electrostatic discharge immunity without external protection components |
| Package | SOD-923 (1.00 × 0.60 × 0.40 mm) - enables high-density placement on compact PCBs such as smartphone mainboards |

FAQ
What is the Zener voltage tolerance for NZ9F16VT5G?
The NZ9F16VT5G has a specified Zener voltage range of 15.2 V to 16.8 V at 5 mA test current, corresponding to a ±5% tolerance around the nominal 16 V rating. This tolerance is guaranteed across the full operating temperature range and is measured under pulse test conditions per the onsemi datasheet.
Is NZ9F16VT5G suitable for automotive applications?
Yes, NZ9F16VT5G is AEC-Q101 qualified and PPAP capable, with full traceability, extended temperature operation (−65 °C to +150 °C), and robust ESD performance (>16 kV HBM). It is explicitly intended for automotive infotainment, body electronics, and ADAS subsystems requiring certified discrete protection devices.
What is the thermal resistance of NZ9F16VT5G and how does it affect layout?
NZ9F16VT5G has a junction-to-ambient thermal resistance (RJA) of 500 °C/W on FR-5 board. This means a 125 mW power dissipation raises junction temperature by 62.5 °C above ambient. Layout must avoid thermal isolation - use minimum 1.0 mm² copper pad with 2+ thermal vias to ground plane for sustained operation near rated power.
Does NZ9F16VT5G have a polarity marking, and how is it identified?
Yes, NZ9F16VT5G uses Style 1 marking per the SOD-923 mechanical drawing: Pin 1 (cathode) is indicated by a polarity band at the banded end of the package. The device marking "R*" appears adjacent to the band, confirming cathode orientation for correct PCB placement and functional clamping direction.
What is the maximum reverse leakage current for NZ9F16VT5G at 12 V?
The maximum reverse leakage current for NZ9F16VT5G is 0.1 µA at 12 V reverse voltage and 25 °C ambient temperature, as specified in the Electrical Characteristics table. This low leakage supports ultra-low-power operation in battery-backed or energy-harvesting systems where standby current must be minimized.
