Product details
Overview
NZ3F5V1T1G from onsemi is a 5.1 V ±0.3 V Zener diode in SOD−323FL package, rated for 800 mW steady-state power dissipation at 25°C, with 80 Ω max Zener impedance at 5 mA test current and 2 µA max reverse leakage at 2 V. It provides precision voltage regulation in space-constrained portable electronics.
For engineers reviewing the NZ3F5V1T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its 5.1 V nominal Zener voltage, 225 pF capacitance at 0 V/1 MHz, −2.7 mV/°C temperature coefficient, AEC−Q101 qualification (SZNZ3F5V1T1G variant), and SOD−323FL footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference by exploiting controlled reverse breakdown in a silicon PN junction. Its Zener voltage is specified at IZT = 5 mA with tight tolerance (4.8–5.4 V), and it maintains stable regulation across −65°C to +150°C junction temperature range.
Thermal design relies on its 156 °C/W junction-to-ambient thermal resistance and 800 mW power rating on FR−4 board; derating begins above 25°C at 6.4 mW/°C. ESD robustness exceeds 16 kV per Human Body Model, supporting handling in automated assembly environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B5V1,115 | 5.1 V ±5%, 300 mW rating, SOD-323 package, 150 Ω Zz @ 5 mA | Lower power handling limits use in surge-prone or higher-current clamp roles | Select when cost sensitivity outweighs power or impedance requirements |

FAQ
What is the nominal Zener voltage of NZ3F5V1T1G and its tolerance range?
The NZ3F5V1T1G has a nominal Zener voltage of 5.1 V with a guaranteed range of 4.8 V to 5.4 V at 5 mA test current (IZT). This 0.6 V total spread reflects ±0.3 V tolerance around the nominal value, making NZ3F5V1T1G suitable for applications requiring tight regulation near standard 5 V logic rails.
Does NZ3F5V1T1G meet automotive qualification standards?
The standard NZ3F5V1T1G is not automotive-qualified, but its variant SZNZ3F5V1T1G is AEC−Q101 qualified and PPAP capable. The SZ prefix denotes automotive-specific process controls and testing; both share identical electrical specs and SOD−323FL packaging, enabling drop-in replacement where qualification is required.
What is the maximum power dissipation of NZ3F5V1T1G and how does it derate with temperature?
NZ3F5V1T1G is rated for 800 mW steady-state power dissipation at 25°C on FR−4 board. Above 25°C, it derates linearly at 6.4 mW/°C, reaching zero dissipation at approximately 150°C ambient. This derating curve is defined in Figure 1 of the datasheet and must be applied in thermal design calculations.
How is polarity identified on the NZ3F5V1T1G SOD−323FL package?
Polarity on NZ3F5V1T1G is marked by a visible cathode band located adjacent to Pin 1 (cathode) on the top surface of the SOD−323FL package. Pin 2 is the anode. This marking aligns with JEDEC-standard SOD−323FL orientation and ensures correct placement during automated pick-and-place assembly.
What is the Zener impedance of NZ3F5V1T1G and why does it matter?
NZ3F5V1T1G has a maximum Zener impedance (ZZT) of 80 Ω at 5 mA test current. This parameter quantifies how much the Zener voltage changes under small-signal AC load variations; lower impedance means better regulation stability, especially important in precision reference and noise-sensitive analog circuits using NZ3F5V1T1G.
