Product details
Overview
NZ9F6V2ST5G from onsemi is a 6.2 V ±4.3% Zener diode in SOD-923 package, rated for 250 mW steady-state power dissipation, with 60 Ω maximum Zener impedance at 5 mA test current and 110 pF capacitance at 0 V/1 MHz - used for precision voltage clamping and ESD protection in space-constrained portable electronics.
For engineers reviewing the NZ9F6V2ST5G datasheet, pinout, applications, or equivalent options, key selection criteria include its tight Zener tolerance (±4.3%), Class 3 HBM ESD rating (>16 kV), low-profile 0.40 mm height, AEC-Q101 qualification (SZ-prefix variant), and compatibility with reflow profiles up to 260 °C.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain stable 6.06–6.33 V across its terminals under regulated current conditions. Its thermal resistance is 500 °C/W, and it supports junction temperatures from −65 °C to +150 °C with derating above 25 °C at 2.0 mW/°C.
The NZ9F6V2ST5G exhibits a positive temperature coefficient of +0.4 mV/°C at 5 mA, enabling predictable drift compensation in bias networks. It delivers 3 µA maximum reverse leakage at VR = 4.8 V and maintains ≤100 Ω dynamic impedance below 10% modulation at IZT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.06 V min to 6.33 V max at 5 mA - defines clamping threshold with ±4.3% tolerance for stable reference design |
| Power Dissipation (PD) | 250 mW at 25 °C - sets maximum continuous energy handling on FR-5 board before thermal derating applies |
| Zener Impedance (ZZT) | 60 Ω max at IZT = 5 mA - ensures low AC impedance for effective noise suppression in regulation paths |
| Reverse Leakage (IR) | 3 µA max at VR = 4.8 V - guarantees minimal standby current in battery-powered circuits |
| Capacitance (C) | 110 pF max at VR = 0 V, f = 1 MHz - constrains high-frequency signal coupling in RF-sensitive interfaces |
| ESD Rating | Class 3 (>16 kV) per HBM - provides robust electrostatic discharge immunity without external protection |
| Package | SOD-923 (1.00 × 0.60 × 0.40 mm) - enables placement on ultra-dense PCBs where footprint and height are critical |

| 2 (Non-banded End) | Anode | Connected to lower-potential node (e.g., ground or return path); completes conduction path when VAK ≥ VZ |
Key Features
| Feature | Design Value |
|---|---|

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-C6V2 | Same 6.2 V nominal, but ±5% tolerance (wider than NZ9F6V2ST5G's ±4.3%); 350 mW PD; SOD-523 package (smaller footprint but same height) | Higher power handling suits higher-current clamp scenarios; tighter layout constraints due to smaller pad area | Select when higher dissipation margin is needed and board real estate permits SOD-523 rework |
| MMSZ4687 | 6.2 V nominal, ±5% tolerance; 500 mW PD; SOD-123 package (larger, 1.8 × 1.4 × 1.1 mm); 30 Ω ZZT at 5 mA | Lower impedance improves regulation stability under varying loads; larger size eases hand-soldering and thermal management | Prefer for industrial control modules requiring long-term reliability and manual assembly compatibility |
Compared with BZX584-C6V2 and MMSZ4687, the NZ9F6V2ST5G offers the tightest voltage tolerance and smallest form factor among the three, making it optimal for miniaturized consumer electronics where precision and space are prioritized over raw power handling.

FAQ
What is the Zener voltage tolerance of NZ9F6V2ST5G?
The NZ9F6V2ST5G has a Zener voltage range of 6.06 V to 6.33 V at 5 mA test current, corresponding to a ±4.3% tolerance. This tight specification is confirmed in the Electrical Characteristics table on page 3 of the onsemi datasheet. The NZ9F6V2ST5G achieves this consistency through process-controlled doping and post-trim testing, making it suitable for applications demanding stable reference accuracy without external calibration.
Is NZ9F6V2ST5G qualified for automotive use?
The base NZ9F6V2ST5G is not automotive-qualified, but its SZ-prefix variant (SZNZ9F6V2ST5G) is AEC-Q101 qualified and PPAP capable. The NZ9F6V2ST5G shares identical electrical and mechanical specs with the SZ version except for traceability and process controls required for automotive production. For automotive designs, specify SZNZ9F6V2ST5G - the NZ9F6V2ST5G itself is intended for commercial portable electronics.
What is the maximum operating temperature for NZ9F6V2ST5G?
The NZ9F6V2ST5G supports a junction and storage temperature range of −65 °C to +150 °C. Its thermal resistance is 500 °C/W, and power must be derated linearly above 25 °C at 2.0 mW/°C. At 85 °C ambient, the maximum allowable power drops to 130 mW. This thermal profile is validated per JEDEC JESD22-A108 and applies directly to the NZ9F6V2ST5G in standard FR-5 board mounting.
Does NZ9F6V2ST5G have a specified forward voltage?
Yes - the NZ9F6V2ST5G has a maximum forward voltage (VF) of 0.9 V at 10 mA forward current, as stated in the datasheet's Electrical Characteristics summary. This parameter is consistent across the entire NZ9FxxxST5G series and reflects the anode-to-cathode drop when used in forward conduction mode, such as in polarity protection or LED driver bias paths.
What does the "T5G" suffix indicate in NZ9F6V2ST5G?
The "T5G" suffix in NZ9F6V2ST5G denotes tape-and-reel packaging: 8,000 units per reel, Pb-free (RoHS-compliant) construction, and compliance with onsemi's BRD8011/D tape specification. The "G" confirms Pb-free status, and "T5" specifies the standard 8 mm carrier tape format. This packaging enables automated pick-and-place assembly and is identical across all NZ9FxxxST5G series devices, including the NZ9F6V2ST5G.
