Product details
Overview
NZ8F6V2MX2WT5G from onsemi is a 250 mW surface-mount Zener diode in X2DFNW2 (0402) package, with nominal Zener voltage 6.2 V (min 5.89 V, max 6.51 V), 60 Ω dynamic impedance at 5 mA test current, and 1 μA leakage current at 3 V reverse bias. It provides precision voltage regulation in space-constrained power rail protection circuits for portable electronics and automotive control units.
For engineers reviewing the NZ8F6V2MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5% standard), wettable flank package for AOI compatibility, thermal resistance (415 °C/W on FR-4 minimum pad), low 0.40 mm body height, and AEC-Q101 qualification when ordered with SZ prefix.
Technical Context
This device operates as a unidirectional voltage reference and overvoltage clamp, conducting in reverse breakdown above its specified VZ while maintaining stable regulation across temperature (−65 °C to +150 °C). Its low capacitance (110 pF at 0 V, 1 MHz) supports high-frequency noise suppression without signal distortion.
The X2DFNW2 package features wettable flanks for reliable solder joint inspection and delivers 250 mW power dissipation on minimal FR-4 board area (1 oz. Cu, minimum pad), with derating of 1.5 mW/°C above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.89 V to 6.51 V @ IZT = 5 mA - defines regulated output voltage range under standard test conditions |
| Power Dissipation (PD) | 250 mW @ TA = 25 °C - maximum continuous power on FR-4 minimum pad; limits thermal design headroom |
| Zener Impedance (ZZT) | 60 Ω @ IZT = 5 mA - determines regulation stiffness and output voltage variation under load changes |
| Reverse Leakage (IR) | 1 μA @ VR = 3 V - ensures minimal standby current in clamping applications below breakdown |
| Capacitance (C) | 110 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency transient response and EMI filtering capability |
| Forward Voltage (VF) | 0.9 V max @ IF = 10 mA - defines conduction loss when used in forward-biased protection paths |
| Thermal Resistance (RJA) | 415 °C/W - governs junction temperature rise under power dissipation; requires thermal pad optimization |
Pinout & Package
The NZ8F6V2MX2WT5G is housed in the X2DFNW2 (Case 711BG) surface-mount package - a 0402-inch (1.00 × 0.60 × 0.37 mm) wettable flank leadless package with 2 terminals. Package dimensions comply with JEDEC MO-252 and support automated optical inspection (AOI).
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 (Anode) | Zener anode terminal | Connected to lower-potential node (e.g., ground or return path); completes reverse-bias circuit |
Key Features
| Feature | Design Value |
|---|---|
| Wettable flank package | Enables 100% automated optical inspection (AOI) of solder joints on fine-pitch 0402 boards |
| Low profile (0.40 mm height) | Reduces mechanical interference in ultra-thin handheld and automotive modules |
| Standard ±5% Zener tolerance | Provides cost-optimized voltage reference accuracy for non-critical regulation tasks |
| Pb-Free, Halogen-Free, RoHS compliant | Meets global environmental compliance requirements without compromising electrical performance |
| AEC-Q101 qualified (with SZ prefix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C6V2 | 6.2 V ±5%, SOD-523 package (1.3 × 0.85 × 0.6 mm), 300 mW PD, 100 Ω ZZT | Larger footprint and higher thermal resistance (500 °C/W); less suitable for ultra-dense layouts | Select when higher power margin is required and board space allows larger package |
| MMSZ4687 | 6.2 V ±5%, SOD-123 package (3.7 × 1.6 × 1.1 mm), 500 mW PD, 100 Ω ZZT | Significantly larger size and higher capacitance (150 pF); not AOI-optimized | Choose for legacy designs using SOD-123 footprints or where higher surge handling is prioritized over miniaturization |
Compared with BZX584-C6V2 and MMSZ4687, the NZ8F6V2MX2WT5G offers superior board-area efficiency (0402), wettable flanks for AOI, and lower thermal resistance on minimal pads-making it optimal for next-generation portable and automotive modules where space, inspection yield, and thermal density are critical.

FAQ
What is the Zener voltage tolerance of NZ8F6V2MX2WT5G?
The NZ8F6V2MX2WT5G has a standard tolerance Zener voltage range of 5.89 V to 6.51 V at IZT = 5 mA, corresponding to ±5% about the nominal 6.2 V rating. This tolerance is confirmed in the Electrical Characteristics table on page 2 of the official onsemi datasheet (Rev. 4, November 2025). The NZ8F6V2MX2WT5G does not feature tight-tolerance (±2%) variants - those are designated with "S" in the part number (e.g., NZ8F6V2SMX2WT5G).
Is NZ8F6V2MX2WT5G qualified for automotive use?
The NZ8F6V2MX2WT5G itself is not automotive-qualified; however, its automotive-grade variant - SZNZ8F6V2MX2WT5G - carries the SZ prefix and is AEC-Q101 qualified and PPAP capable. The base NZ8F6V2MX2WT5G shares identical electrical specs and packaging but lacks the extended reliability validation required for automotive applications. Always specify the SZ prefix when automotive qualification is mandatory for NZ8F6V2MX2WT5G.
What is the maximum power dissipation of NZ8F6V2MX2WT5G on a standard PCB?
The NZ8F6V2MX2WT5G delivers 250 mW total device dissipation on an FR-4 board with minimum pad layout and 1 oz. copper (Note 1 in Maximum Ratings table). Power must be derated linearly by 1.5 mW/°C above 25 °C ambient. This rating assumes no thermal vias or enhanced copper pours - actual dissipation may increase to 500 mW with optimized 150 mm² copper area, per Note 2.
Does NZ8F6V2MX2WT5G support automated optical inspection (AOI)?
Yes, the NZ8F6V2MX2WT5G uses the X2DFNW2 package with wettable flanks, explicitly designed for optimal automated optical inspection (AOI). The side-wettable terminations allow full solder fillet visibility under standard AOI systems, improving first-pass yield in high-volume SMT assembly. This feature is highlighted in the Specification Features section of the onsemi datasheet.
What is the reverse leakage current specification for NZ8F6V2MX2WT5G?
The NZ8F6V2MX2WT5G specifies a maximum reverse leakage current (IR) of 1 μA at VR = 3 V, measured at TA = 25 °C. This value is documented in the Electrical Characteristics table (page 2) and reflects the device's ability to minimize standby power loss in clamping or reference configurations operating below its Zener breakdown threshold.
