Product details
Overview
NZ8F5V6MX2WT5G from onsemi is a 5.6 V ±5% Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C on FR-4 board with 1.5 mW/°C derating, 115 pF capacitance at 0 V/1 MHz, and 1 µA leakage at 2.5 V reverse bias - used for precision voltage clamping in space-constrained portable electronics.
For engineers reviewing the NZ8F5V6MX2WT5G 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 thermal resistance of 415 °C/W on minimal-pad FR-4 layout.
Technical Context
This device operates as a unidirectional voltage reference and transient clamp, leveraging silicon PN junction Zener breakdown at nominal 5.6 V with tight regulation across 5 mA test current. Its low dynamic impedance (60 Ω max at IZT) ensures stable clamping under varying load conditions.
The X2DFNW2 package enables automated optical inspection via solderable side walls and supports high-density PCB layouts typical in mobile and automotive control units. Thermal performance is defined for two board configurations: minimal-pad (250 mW/415 °C/W) and 150 mm² copper (500 mW/247 °C/W), with junction temperature range from −65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.32–5.88 V at 5 mA - defines precise clamping threshold for overvoltage protection circuits |
| Power Dissipation (PD) | 250 mW on minimal FR-4 pad - sets maximum continuous power handling without forced cooling |
| Zener Impedance (ZZT) | ≤60 Ω at 5 mA - ensures minimal voltage shift during transient current surges |
| Reverse Leakage (IR) | ≤1 µA at 2.5 V - guarantees low standby current in battery-powered systems |
| Capacitance (C) | 115 pF at 0 V, 1 MHz - impacts high-frequency noise filtering and signal integrity in RF-adjacent traces |
| Package | X2DFNW2 (0402, 1.00 × 0.60 × 0.37 mm) - enables ultra-compact placement and AOI-compatible solder joint inspection |
| Thermal Resistance (RJA) | 415 °C/W on minimal-pad FR-4 - determines required board copper area for thermal management |
Pinout & Package
X2DFNW2 is a 2-terminal surface-mount package with wettable flank sidewalls for AOI. Dimensions: 1.00 mm × 0.60 mm × 0.37 mm, 0.65 mm pitch, 0.40 mm body height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener cathode terminal | Connected to regulated voltage rail; reverse-biased operation requires this node at higher potential than anode |
| 2 (Anode) | Zener anode terminal | Connected to ground or lower-potential reference; completes conduction path during Zener breakdown |
Key Features
| Feature | Design Value |
|---|---|
| Wettable Flank Package | Enables reliable automated optical inspection of solder joints on both top and side surfaces |
| AEC-Q101 Qualification Path | SZ-prefix variant available for automotive applications requiring PPAP documentation and site-specific controls |
| Pb-Free / Halogen-Free | Complies with RoHS Directive 2011/65/EU and JEDEC JS709B halogen-free requirements |
| Low Profile Height | 0.40 mm max - reduces mechanical interference in stacked or shielded assemblies |
| Stable Temperature Coefficient | Typical ±0.05 %/°C near 5.6 V - minimizes drift over industrial temperature range (−65 °C to +150 °C) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F | 5.1 V nominal, ±5%, SOT-323 package (1.7 × 1.3 × 0.9 mm), 350 mW rating | Larger footprint and higher profile limit use in 0402-constrained layouts; higher power suits higher-current clamping | Select when board space permits larger package and higher dissipation is needed; not suitable for AOI-critical or ultra-thin assemblies |
| BZX384-B5V6,115 | 5.6 V nominal, ±5%, SOD-323 package (1.7 × 1.3 × 0.9 mm), 300 mW rating, 150 pF capacitance | Higher capacitance degrades high-frequency signal integrity; same thermal resistance but larger land pattern | Prefer for cost-sensitive consumer applications where 150 pF capacitance is acceptable and AOI is not required |
Compared with MMBZ5232BS-7-F and BZX384-B5V6,115, the NZ8F5V6MX2WT5G delivers superior board-area efficiency, AOI compatibility, and lower parasitic capacitance - critical for miniaturized, high-reliability designs where 0402 placement and automated inspection are mandatory.

FAQ
What is the Zener voltage tolerance of NZ8F5V6MX2WT5G?
The NZ8F5V6MX2WT5G has a Zener voltage tolerance of ±5% - specified as 5.32 V minimum and 5.88 V maximum at 5 mA test current (IZT). This standard tolerance series (denoted by "M" in the part number) balances cost and precision for general-purpose clamping applications where tight regulation is not mission-critical. The tighter ±2.5% variant is NZ8F5V6SMX2WT5G.
Is NZ8F5V6MX2WT5G qualified for automotive use?
NZ8F5V6MX2WT5G itself is not AEC-Q101 qualified, but its SZ-prefix variant - SZNZ8F5V6MX2WT5G - is fully AEC-Q101 qualified and PPAP capable. The base NZ8F5V6MX2WT5G shares identical electrical and mechanical specifications, differing only in manufacturing site controls and documentation traceability required for automotive Tier 1 supply chains.
What is the maximum reverse leakage current for NZ8F5V6MX2WT5G?
The maximum reverse leakage current for NZ8F5V6MX2WT5G is 1 µA at 2.5 V reverse bias (VR), measured at 25 °C. This low leakage supports extended battery life in always-on portable devices. Leakage increases with temperature and reverse voltage - at 125 °C and 2.5 V, typical leakage rises to ~10 µA, per onsemi's characterization curves.
Can NZ8F5V6MX2WT5G be used for ESD protection?
Yes, NZ8F5V6MX2WT5G is routinely deployed for secondary ESD protection in conjunction with primary TVS diodes. Its 5.6 V Zener voltage provides clamping just above normal operating rails, and its 115 pF capacitance avoids signal distortion on moderate-speed lines (e.g., I²C, UART). For direct IEC 61000-4-2 contact discharge protection, pairing with a low-capacitance TVS (e.g., ESD5Z5.0T1G) is recommended.
What does the "X2WT5G" suffix indicate in NZ8F5V6MX2WT5G?
The "X2WT5G" suffix denotes the package and packaging format: "X2" = X2DFNW2 package, "W" = wettable flank feature, "T5" = tape-and-reel packaging (8,000 units per reel), and "G" = Pb-free and RoHS-compliant construction. This suffix is consistent across the NZ8FxxxMX2WT5G family and confirms full compliance with JEDEC J-STD-020 moisture sensitivity level 1 (MSL1).
