Product details
Overview
NZ8F2V4MX2WT5G from onsemi is a 2.4 V ±12% standard-tolerance Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C on FR-4 board with 1 oz. Cu, 0.40 mm body height, and 210 pF capacitance at 0 V/1 MHz - used for precision voltage clamping in space-constrained power rails of portable electronics.
For engineers reviewing the NZ8F2V4MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 2.11–2.69 V Zener range at 5 mA, 100 Ω dynamic impedance, 50 µA leakage at 1 V reverse bias, wettable flank geometry for AOI compatibility, and AEC-Q101 qualification when ordered with SZ prefix.
Technical Context
This unidirectional Zener diode operates in reverse breakdown to regulate or clamp voltage with low-profile surface-mount integration. Its X2DFNW2 package features solderable flank sidewalls enabling automated optical inspection and high-reliability reflow soldering on dense PCBs.
The device delivers stable 2.4 V reference behavior across −65 °C to +150 °C junction temperature, with thermal resistance of 415 °C/W (FR-4 minimum pad), 0.9 V forward voltage at 10 mA, and temperature coefficient optimized for low-drift performance in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.11–2.69 V at IZT = 5 mA - defines clamping threshold for overvoltage protection in 2.5 V logic rails. |
| Power Dissipation (PD) | 250 mW at TA = 25 °C (FR-4, 1 oz. Cu, min pad) - sets maximum continuous clamping energy without thermal runaway. |
| Zener Impedance (ZZT) | 100 Ω max at IZT = 5 mA - determines regulation stiffness under dynamic load transients. |
| Reverse Leakage (IR) | 50 µA max at VR = 1 V - ensures minimal quiescent current draw in always-on circuits. |
| Capacitance (C) | 210 pF at VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and signal integrity in RF-adjacent layouts. |
| Package | X2DFNW2 (0402, 1.00 × 0.60 × 0.37 mm) with wettable flanks - enables AOI verification and high-yield assembly in fine-pitch designs. |
| Compliance | AEC-Q101 qualified (with SZ prefix), RoHS, Pb-free, halogen-free/BFR-free - supports automotive and industrial reliability requirements. |
Pinout & Package
X2DFNW2 is a 2-terminal surface-mount package with exposed copper flanks for solder joint inspection. Terminal 1 is cathode (marked), Terminal 2 is anode - polarity critical for correct reverse-bias operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to regulated node; reverse-biased voltage reference point requiring proper polarity routing. |
| 2 (Anode) | Reference ground return | Tied to system ground or lower-potential rail; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Wettable flank geometry | Enables 100% automated optical inspection of solder fillets on ultra-small 0402 footprint without X-ray. |
| Low 0.40 mm profile | Reduces board stack height and mechanical interference in stacked modules or thin handheld enclosures. |
| 250 mW FR-4-rated power | Supports transient suppression in 3.3 V and 2.5 V supply domains without derating on standard PCBs. |
| 210 pF junction capacitance | Provides effective high-frequency bypassing for ESD and RF coupling while avoiding resonance issues below 100 MHz. |
| AEC-Q101 qualification path | Validated stress testing enables use in automotive control units where field reliability is non-negotiable. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V4,115 (Nexperia) | Same 2.4 V nominal, ±5% tolerance, SOD-323 package (1.7 × 1.3 mm), 300 mW rating, 250 pF capacitance. | Larger footprint and higher capacitance limit use in >50 MHz signal paths; lacks wettable flanks for AOI. | Select when higher power margin is needed and board area allows SOD-323; not drop-in for 0402 layouts. |
| MMSZ4676T1G (onsemi) | 2.4 V nominal, ±5% tolerance, SOD-123 package (3.5 × 1.8 mm), 500 mW rating, 200 pF capacitance, AEC-Q101 qualified. | 3× larger footprint; better thermal dissipation but incompatible with ultra-dense 0402 routing constraints. | Choose for industrial power supplies needing higher surge handling; requires PCB redesign vs. NZ8F2V4MX2WT5G. |

FAQ
What is the Zener voltage tolerance of NZ8F2V4MX2WT5G?
The NZ8F2V4MX2WT5G has a standard tolerance of ±12% around its nominal 2.4 V rating, resulting in a guaranteed reverse breakdown range of 2.11 V to 2.69 V at 5 mA test current per the datasheet's Electrical Characteristics table. This tolerance reflects the MX2W series designation and is distinct from the tighter ±5% tolerance offered in the SMX2W variant.
Is NZ8F2V4MX2WT5G qualified for automotive use?
The NZ8F2V4MX2WT5G itself is not automatically automotive-qualified; however, the same die and package are AEC-Q101 qualified when ordered with the SZ prefix (SZNZ8F2V4MX2WT5G). The base part meets RoHS, Pb-free, and halogen-free requirements but requires the SZ version for PPAP-capable automotive production.
What is the maximum operating temperature for NZ8F2V4MX2WT5G?
The NZ8F2V4MX2WT5G has a specified junction and storage temperature range of −65 °C to +150 °C. Its thermal resistance is 415 °C/W on FR-4 with minimum pad layout, meaning sustained operation above 125 °C ambient requires careful power derating - e.g., maximum 125 mW at 75 °C ambient per the Steady State Power Derating curve.
Does NZ8F2V4MX2WT5G support automated optical inspection (AOI)?
Yes - the X2DFNW2 package of NZ8F2V4MX2WT5G features wettable flanks, meaning the side walls of the terminals are fully solderable and visible to AOI systems. This enables reliable, non-destructive solder joint inspection without requiring X-ray, a key advantage over standard 0402 chip diodes.
What is the forward voltage of NZ8F2V4MX2WT5G at 10 mA?
The forward voltage of NZ8F2V4MX2WT5G is specified as ≤0.9 V at IF = 10 mA, consistent across all NZ8FxxxMX2W devices. This low VF ensures minimal conduction loss when used in forward-biased configurations such as ESD protection diode pairs or level-shifting networks.
