Product details
Overview
NZ8F4V7MX2WT5G from onsemi is a 4.7 V ±5% Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C on FR-4 board with 1 oz. Cu, 415 °C/W junction-to-ambient thermal resistance, and 2 pA reverse leakage at 1 V. It provides precision voltage regulation in space-constrained portable electronics.
For engineers reviewing the NZ8F4V7MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), low-profile 0.40 mm height, AOI-compatible wettable flanks, AEC-Q101 qualification eligibility via SZ prefix, and 150 pF capacitance at 0 V bias for ESD-sensitive signal lines.
Technical Context
This device operates as a unidirectional voltage reference diode, clamping reverse voltage at nominal 4.7 V with tight regulation across 5 mA test current. Its low dynamic impedance (100 Ω max at IZT = 5 mA) ensures stable regulation under varying load conditions.
The X2DFNW2 package enables automated optical inspection via solderable side walls, while its 0402 footprint supports high-density PCB layouts. Thermal performance is defined for two board configurations: 250 mW/415 °C/W (minimum pad) and 500 mW/247 °C/W (150 mm² copper area), allowing design flexibility based on layout constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.47 V min to 4.94 V max at IZT = 5 mA - defines regulated output range for overvoltage protection circuits |
| Power Dissipation (PD) | 250 mW @ 25 °C on FR-4 (1 oz. Cu, minimum pad) - sets maximum continuous power handling without derating |
| Zener Impedance (ZZT) | ≤100 Ω @ IZT = 5 mA - ensures minimal voltage shift under dynamic load transients |
| Reverse Leakage (IR) | ≤2 pA @ VR = 1 V - critical for ultra-low-power biasing and sensing applications |
| Capacitance (C) | 150 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and ESD clamp response time |
| Package | X2DFNW2 (0402, 1.00 × 0.60 × 0.37 mm) - enables miniaturized layouts with AOI-compatible wettable flanks |
| Junction Temp Range | −65 °C to +150 °C - supports operation in automotive under-hood and industrial environments |
Pinout & Package
The NZ8F4V7MX2WT5G uses the X2DFNW2 surface-mount package (Case 711BG), measuring 1.00 mm × 0.60 mm × 0.37 mm with 0.65 mm pitch and wettable flank sidewalls for reliable AOI inspection. It has two terminals: Cathode (Pin 1) and Anode (Pin 2), marked on the top surface per device-specific code "AJ".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener voltage reference node | Connected to regulated rail or signal line requiring clamping; polarity must be observed to avoid forward conduction |
| 2 (Anode) | Reference ground return | Typically tied to system ground or low-impedance return path; forms complete regulation loop with cathode |
Key Features
| Feature | Design Value |
|---|---|
| Wettable Flank Package | Enables 100% automated optical inspection of solder joints on 0402 footprint without X-ray |
| AEC-Q101 Eligibility | SZ-prefixed variants (e.g., SZNZ8F4V7MX2WT5G) meet automotive stress testing requirements |
| Pb-Free / RoHS Compliance | Fully compliant with EU RoHS Directive 2011/65/EU and halogen-free/BFR-free manufacturing |
| Low Body Height | 0.40 mm max profile allows stacking under shields or in ultra-thin handheld enclosures |
| Standard Tolerance Series | ±5% VZ tolerance (NZ8FxxxMX2WT5G) balances cost and precision for non-critical regulation |

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-C4V7 | 4.7 V ±5%, SOD-523 package (1.2 × 0.8 × 0.6 mm), 350 mW PD, 180 pF C | Larger footprint; higher capacitance reduces suitability for >1 MHz signal lines | Select when higher power margin is needed and board space permits larger package |

FAQ
What is the Zener voltage tolerance of NZ8F4V7MX2WT5G?
The NZ8F4V7MX2WT5G has a Zener voltage tolerance of ±5%, specified as 4.47 V minimum to 4.94 V maximum at IZT = 5 mA and TA = 25 °C. This tolerance is confirmed in the Electrical Characteristics table on page 2 of the official onsemi datasheet (Rev. 4, November 2025). The NZ8F4V7MX2WT5G belongs to the standard tolerance series (denoted by "M" in the part number suffix).
Does NZ8F4V7MX2WT5G support automotive-grade qualification?
The NZ8F4V7MX2WT5G itself is not automotive-qualified, but its SZ-prefixed variant-SZNZ8F4V7MX2WT5G-is AEC-Q101 qualified and PPAP capable. The base NZ8F4V7MX2WT5G shares identical electrical and mechanical specifications, differing only in traceability and process controls required for automotive use. Both use the same X2DFNW2 package and exhibit identical Zener voltage, leakage, and thermal characteristics.
What is the maximum reverse leakage current for NZ8F4V7MX2WT5G?
The maximum reverse leakage current for NZ8F4V7MX2WT5G is 2 pA at VR = 1 V and TA = 25 °C, as specified in the Electrical Characteristics table. This ultra-low leakage supports precision biasing in high-impedance analog circuits and extends battery life in always-on portable devices powered by the NZ8F4V7MX2WT5G.
Can NZ8F4V7MX2WT5G be used in high-frequency signal paths?
Yes, the NZ8F4V7MX2WT5G exhibits 150 pF capacitance at 0 V bias and 1 MHz, making it suitable for ESD protection and DC biasing in signal paths up to ~10 MHz. Its low capacitance minimizes loading on high-speed lines, and its 100 Ω dynamic impedance ensures fast transient response-key attributes confirmed in the Typical Characteristics section (Figures 5 and 7) of the NZ8F4V7MX2WT5G datasheet.
What is the thermal resistance (RJA) of NZ8F4V7MX2WT5G on a standard PCB?
The junction-to-ambient thermal resistance (RJA) of NZ8F4V7MX2WT5G is 415 °C/W when mounted on an FR-4 board with minimum pad size and 1 oz. copper. This value assumes the standard test condition noted in the Maximum Ratings table (Note 1). For enhanced thermal performance, the device supports 247 °C/W with a 150 mm² copper area (Note 2), both validated in the NZ8F4V7MX2WT5G datasheet.
