Product details
Overview
NZ8F3V6MX2WT5G from onsemi is a 3.35 V to 3.85 V Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation on FR-4 board at 25 °C with 100 Ω dynamic impedance at 5 mA test current and 10 nA leakage at 1 V reverse bias - used for precision voltage clamping in space-constrained portable power rails.
For engineers reviewing the NZ8F3V6MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±7.5%), low-profile 0.40 mm height, AEC-Q101 qualification eligibility via SZ prefix, and compatibility with automated optical inspection due to wettable flank geometry.
Technical Context
This device operates as a unidirectional Zener regulator with specified reverse breakdown behavior under DC and transient conditions. It exhibits 10 pF capacitance at 0 V bias and 1 MHz, temperature coefficient of ±9 mV/°C (typical), and forward voltage ≤0.9 V at 10 mA - enabling stable clamping in low-noise analog and mixed-signal supply domains.
The X2DFNW2 package supports high-density PCB layouts with solder joint visibility for AOI, while thermal resistance of 415 °C/W (FR-4 minimum pad) defines its steady-state power handling. Derating begins above 25 °C at 1.5 mW/°C, limiting usable dissipation in elevated ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage Range | 3.35 V to 3.85 V at IZT = 5 mA - defines clamping threshold for 3.3 V rail protection |
| Power Dissipation | 250 mW on FR-4 (1 oz Cu, min pad) - sets maximum continuous clamp energy without derating |
| Zener Impedance | 100 Ω max at IZT = 5 mA - determines regulation stiffness under load transients |
| Leakage Current | 10 nA max at VR = 1 V - ensures minimal standby current draw in battery-powered systems |
| Capacitance | 210 pF at VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering capability |
| Package | X2DFNW2 (0402, 1.00 × 0.60 × 0.37 mm) - enables placement in ultra-compact mobile PCBs |
| AEC-Q101 Eligibility | SZ prefix variant available - supports automotive control unit deployment with PPAP documentation |
Pinout & Package
The NZ8F3V6MX2WT5G uses the X2DFNW2 surface-mount package (Case 711BG), measuring 1.00 mm × 0.60 mm × 0.37 mm with wettable flank sidewalls for AOI-compatible solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener anode connection point | Connected to regulated voltage node; polarity must be observed to avoid forward conduction |
| 2 (Anode) | Zener cathode connection point | Typically tied to ground or lower-potential reference; reverse-biased during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Wettable Flank Geometry | Enables reliable automated optical inspection of solder fillets on 0402 footprint without x-ray |
| Low Body Height | 0.40 mm max - allows stacking under shields or beneath tight mechanical clearances |
| Pb-Free / RoHS Compliance | Meets global environmental directives without compromising Zener performance or reliability |
| Standard Tolerance Series | ±7.5% VZ tolerance - balances cost and precision for non-critical clamping applications |
| High-Temp Operation | Junction range −65 °C to +150 °C - supports under-hood automotive and industrial environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | 3.3 V nominal, ±5% tolerance, SOD-523 package (1.2 × 0.8 mm), 200 mW rating | Larger footprint and higher leakage (500 nA @ 1 V); lacks wettable flank geometry | Select when AOI is not required and board space permits larger 0603-equivalent layout |
| BZX384-C3V6,115 | 3.6 V nominal, ±5% tolerance, SOD-323 package (1.7 × 1.3 mm), 300 mW rating | Higher power but 4× larger area; no AEC-Q101 option; 300 pF capacitance limits HF use | Prefer for industrial designs needing higher surge margin where size is secondary |
Compared with MMBZ5226BS-7-F and BZX384-C3V6,115, the NZ8F3V6MX2WT5G delivers superior board-area efficiency (0402), AOI-ready solder joints, and tighter thermal resistance control - critical for miniaturized consumer and automotive modules where traceability and process yield are prioritized.

FAQ
What is the exact Zener voltage range for NZ8F3V6MX2WT5G at 5 mA test current?
The NZ8F3V6MX2WT5G has a guaranteed Zener voltage range of 3.35 V to 3.85 V when tested at IZT = 5 mA and TA = 25 °C, per the onsemi datasheet Electrical Characteristics table. This ±7.5% tolerance reflects the standard series specification and applies to all units shipped under this part number.
Does NZ8F3V6MX2WT5G support automotive qualification?
The NZ8F3V6MX2WT5G itself is not AEC-Q101 qualified, but its SZ-prefixed variant - SZNZ8F3V6MX2WT5G - is explicitly designated for automotive applications and meets AEC-Q101 stress testing requirements with PPAP capability. The base part shares identical electrical and mechanical specs except for traceability and process controls.
What is the maximum allowable junction temperature for NZ8F3V6MX2WT5G?
The NZ8F3V6MX2WT5G has a specified junction and storage temperature range of −65 °C to +150 °C. Operation beyond +150 °C risks permanent degradation; derating must be applied above 25 °C ambient using the 1.5 mW/°C slope on FR-4 minimum-pad boards to maintain safe junction temperatures.
How does the wettable flank feature of NZ8F3V6MX2WT5G improve manufacturing yield?
The wettable flank design of NZ8F3V6MX2WT5G exposes solderable metal along the side walls of the X2DFNW2 package, enabling automated optical inspection systems to verify solder fillet formation without x-ray. This reduces false call rates in high-volume SMT lines and improves first-pass yield for 0402-class components.
Can NZ8F3V6MX2WT5G replace older 3.6 V Zeners like BZX84-C3V6 in new designs?
Yes, NZ8F3V6MX2WT5G can replace BZX84-C3V6 in new designs where board space, AOI compatibility, and modern environmental compliance are priorities - provided the 3.35–3.85 V range and 250 mW rating meet system requirements. Its smaller 0402 footprint and wettable flank offer tangible layout and process advantages over the SOT-23 package.
