Product details
Overview
NZ9F8V2T5G from onsemi is a 250 mW, 8.2 V Zener voltage regulator diode in SOD−923 package, with reverse breakdown voltage range 7.79–8.61 V at 5 mA test current, maximum Zener impedance of 30 Ω at IZT and 60 Ω at IZK, and ESD rating >16 kV (HBM). It provides precision voltage clamping for low-power portable electronics.
For engineers reviewing the NZ9F8V2T5G datasheet, pinout, applications, or equivalent options, key selection factors include its 8.2 V nominal Zener voltage, 250 mW power rating, SOD−923 footprint, AEC−Q101 qualification (SZ prefix variant), and 90 pF capacitance at 0 V/1 MHz - critical for EMI-sensitive signal line protection.
Technical Context
This device operates as a two-terminal voltage reference and transient clamp, conducting in reverse bias above its specified Zener voltage to maintain stable voltage across load circuits. Its low 0.40 mm body height and 1.00 mm × 0.60 mm outline enable high-density PCB integration.
Designed for space-constrained applications, it delivers stable regulation under steady-state DC conditions with thermal resistance of 500 °C/W and junction temperature range from −65 °C to +150 °C. The 100% matte tin lead finish supports lead-free reflow up to 260 °C and meets MSL 1 requirements.
Key Specifications

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-C8V2 | Same 8.2 V nominal Zener voltage but 300 mW rating and SOD-323 package (1.7 × 1.3 mm) | Larger footprint; higher power margin but less suitable for ultra-dense layouts | Choose when higher surge energy absorption is required and board space permits larger package |
| MMSZ4687T1G | 8.2 V Zener, 500 mW rating, SOD-123 package (3.7 × 1.6 mm), 100 Ω ZZT | Higher power and lower cost, but 3× larger size and higher impedance degrades regulation accuracy | Prefer for cost-sensitive industrial controls where layout density is not constrained |
Compared with BZX584-C8V2 and MMSZ4687T1G, NZ9F8V2T5G offers the smallest footprint (1.00 × 0.60 mm), lowest capacitance (90 pF), and tightest voltage tolerance (±5%) - making it optimal for space-limited, high-frequency, and automotive-grade designs requiring precise clamping.

FAQ
What is the nominal Zener voltage of NZ9F8V2T5G and how tightly is it specified?
The nominal Zener voltage of NZ9F8V2T5G is 8.2 V, with a guaranteed range of 7.79 V to 8.61 V at IZT = 5 mA and TA = 25°C. This ±5% tolerance ensures predictable clamping behavior in precision voltage reference and overvoltage protection circuits. The NZ9F8V2T5G achieves this specification using process-controlled doping and laser trimming during manufacturing.
Is NZ9F8V2T5G qualified for automotive applications?
Yes, the SZ-prefix variant SZNZ9F8V2T5G is AEC−Q101 qualified and PPAP capable. While NZ9F8V2T5G itself carries the standard commercial marking, its identical die and construction are validated for automotive use. Engineers specifying NZ9F8V2T5G for automotive systems should order the SZ-prefixed version to ensure full qualification documentation and traceability.
What is the maximum operating temperature range for NZ9F8V2T5G?
NZ9F8V2T5G has a junction and storage temperature range of −65 °C to +150 °C. This wide range supports deployment in harsh environments including under-hood automotive locations and industrial motor drives. Derating begins above 25 °C at 2.0 mW/°C, maintaining safe operation up to the absolute maximum limit.
Does NZ9F8V2T5G have RoHS and halogen-free compliance?
Yes, NZ9F8V2T5G is Pb−Free, halogen-free/BFR-free, and fully RoHS compliant. Its epoxy mold compound meets UL 94 V−0 flammability rating, and the 100% matte tin lead finish complies with JEDEC J-STD-020 moisture sensitivity level 1 requirements for lead-free reflow soldering up to 260 °C.
How does the 90 pF capacitance of NZ9F8V2T5G affect its use in high-speed signal lines?
The 90 pF capacitance of NZ9F8V2T5G at VR = 0 V and f = 1 MHz makes it suitable for ESD protection on moderate-speed interfaces like I²C or UART, but not recommended for >10 Mbps USB or HDMI signal paths where lower capacitance (<10 pF) is required. For NZ9F8V2T5G, this value balances clamping effectiveness with acceptable signal rise-time degradation in portable electronics.
