Product details
Overview
NZ9F6V2T5G from onsemi is a 250 mW, 6.2 V Zener voltage regulator diode in SOD-923 surface-mount package, designed for precision voltage clamping and ESD-sensitive signal line protection in space-constrained portable electronics. It delivers ±5% Zener voltage tolerance (5.89–6.51 V), 60 Ω maximum Zener impedance at 5 mA test current, and 3.7 µA reverse leakage at 3 V, enabling stable reference and overvoltage suppression in low-power analog rails.
For engineers reviewing the NZ9F6V2T5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 6.2 V regulation accuracy, 110 pF capacitance at 0 V, Class 3 HBM ESD rating (>16 kV), SOD-923 footprint compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a two-terminal, silicon planar Zener diode with sharp reverse breakdown characteristics optimized for low-current regulation and transient voltage suppression. Its thermal resistance of 500 °C/W and 250 mW power dissipation at 25 °C enable stable operation in thermally limited PCB layouts without forced cooling.
The NZ9F6V2T5G exhibits a positive temperature coefficient of +0.4 mV/°C for VZ, ensuring predictable voltage drift across −65 °C to +150 °C junction temperature range. Its 100% matte tin lead finish, MSL 1 reflow rating (260 °C), and Pb-free/RoHS-compliant construction support high-yield automated assembly in consumer and automotive production lines.

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 350 mW PD, SOD-523 package (1.2 × 0.8 mm), higher ZZT (100 Ω) | Larger footprint; better for higher-power clamping but less suitable for ultra-dense layouts | Select when higher surge energy handling is required and board area permits larger package |
| MMSZ4687T1G | 6.2 V nominal, 500 mW PD, SOD-123 package (3.7 × 1.6 mm), ZZT = 100 Ω, no AEC-Q101 rating | Significantly larger size; lacks automotive qualification; higher leakage (3 µA @ 3 V) | Choose for cost-sensitive industrial applications where qualification and miniaturization are not critical |
Compared with BZX584-C6V2 and MMSZ4687T1G, the NZ9F6V2T5G offers the smallest footprint (SOD-923), lowest capacitance (110 pF), and only part among the three with AEC-Q101 qualification-making it uniquely suited for next-generation automotive and portable electronics demanding miniaturization, speed, and reliability.

FAQ
What is the Zener voltage tolerance of NZ9F6V2T5G?
The NZ9F6V2T5G has a specified Zener voltage range of 5.89 V to 6.51 V at 5 mA test current, corresponding to a ±5% tolerance around the nominal 6.2 V rating. This tight tolerance is confirmed in the Electrical Characteristics table on page 3 of the onsemi datasheet (Rev. 5, September 2025). The NZ9F6V2T5G maintains this specification across ambient temperatures from −65 °C to +150 °C, with a documented temperature coefficient of +0.4 mV/°C.
Is NZ9F6V2T5G qualified for automotive applications?
Yes, the NZ9F6V2T5G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the "Specification Features" section of the onsemi datasheet. The "SZ" prefix variants (e.g., SZNZ9F6V2T5G) are designated for automotive use, but the standard NZ9F6V2T5G shares identical qualification status per the datasheet's note: "SZ Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC-Q101 Qualified and PPAP Capable." This makes NZ9F6V2T5G suitable for under-hood and cabin electronics.
What is the maximum reverse leakage current for NZ9F6V2T5G?
The maximum reverse leakage current (IR) for NZ9F6V2T5G is 1 µA at VR = 3 V, as specified in the Electrical Characteristics table on page 3 of the onsemi datasheet. This low leakage ensures minimal quiescent current draw in battery-powered systems. At VR = 0 V, leakage is effectively zero; at higher reverse voltages approaching VZ, leakage increases nonlinearly but remains within safe operational limits defined by the device's power rating.
Does NZ9F6V2T5G have an ESD rating, and if so, what is it?
Yes, the NZ9F6V2T5G carries an ESD rating of Class 3 per the Human Body Model (HBM), exceeding 16 kV. This is clearly stated in the "Specification Features" section of the onsemi datasheet. The high ESD robustness is achieved through process design and packaging, making NZ9F6V2T5G appropriate for protecting sensitive inputs in handheld devices, USB interfaces, and automotive sensor nodes exposed to frequent human contact.
What is the thermal resistance and power derating behavior of NZ9F6V2T5G?
The NZ9F6V2T5G has a junction-to-ambient thermal resistance (RJA) of 500 °C/W on FR-5 board, with a steady-state power dissipation limit of 250 mW at 25 °C ambient. Power must be linearly derated at 2.0 mW/°C above 25 °C, as shown in Figure 1 of the datasheet. At 85 °C ambient, the usable power drops to approximately 130 mW. This derating curve is validated for standard SOD-923 mounting on minimum FR-4 pads per Note 1.
