Product details
Overview
NZ8F10VMX2WT5G from onsemi is a 10 V Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C on FR-4 with 1 oz. Cu, 0.40 mm body height, and 80 pF capacitance at 0 V/1 MHz. It delivers precise voltage regulation in space-constrained portable electronics and automotive control units.
For engineers reviewing the NZ8F10VMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include its ±5% Zener tolerance (9.5–10.5 V), 30 Ω dynamic impedance at 5 mA, 0.1 µA leakage at 7 V, AEC-Q101 qualification eligibility via SZ prefix, and wettable flank geometry for AOI compatibility.
Technical Context
This unidirectional Zener diode operates in reverse breakdown to clamp voltage transients and stabilize reference nodes. Its low 0.40 mm profile and wettable flank terminations support high-density PCB layouts and automated optical inspection in automotive and portable designs.
The device exhibits a nominal temperature coefficient of +9 mV/°C (typical) over −55 °C to +150 °C, forward voltage ≤0.9 V at 10 mA, and thermal resistance of 415 °C/W (Junction-to-Ambient, minimum pad). It is Pb-free, halogen-free/BFR-free, and RoHS compliant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.50–10.50 V @ IZT = 5 mA - defines clamping threshold for overvoltage protection |
| Zener Impedance (ZZT) | 30 Ω max @ IZT = 5 mA - ensures stable regulation under load variation |
| Reverse Leakage (IR) | 0.1 µA max @ VR = 7 V - minimizes standby power loss in battery-powered systems |
| Capacitance (C) | 80 pF max @ VR = 0 V, f = 1 MHz - limits signal distortion in high-frequency bias networks |
| Power Dissipation (PD) | 250 mW @ TA = 25 °C (FR-4, 1 oz. Cu, min pad) - sets thermal design margin for compact layouts |
| Package | X2DFNW2 (0402, 1.00 × 0.60 × 0.37 mm) - enables 0402 footprint compatibility and AOI-ready solder joints |
| Operating Temp | −65 °C to +150 °C - supports under-hood automotive and industrial ambient conditions |
Pinout & Package
The NZ8F10VMX2WT5G uses the X2DFNW2 surface-mount package (Case 711BG), featuring a low-profile 0402 footprint (1.00 mm × 0.60 mm × 0.37 mm) with wettable flank side walls for reliable solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener cathode terminal | Connected to regulated voltage node; polarity must be observed for proper breakdown operation |
| 2 (Anode) | Zener anode terminal | Connected to ground or lower-potential reference; completes reverse-bias path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Wettable Flank Termination | Enables 100% automated optical inspection (AOI) of solder fillets without X-ray, reducing post-SMT defect escapes |
| AEC-Q101 Qualification Path | SZ-prefix variant available (SZNZ8F10VMX2WT5G) for automotive applications requiring PPAP documentation and site-specific controls |
| Low Profile Height | 0.40 mm maximum body height - preserves vertical clearance in stacked or shielded assemblies |
| Pb-Free / RoHS Compliance | Fully compliant with EU RoHS Directive 2011/65/EU and JESD97; halogen-free/BFR-free construction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B10,115 | 10 V ±5%, SOD-323 package (1.7 × 1.25 × 0.95 mm), 300 mW PD, 90 Ω ZZT | Larger footprint; higher ZZT reduces regulation precision; no wettable flank | Select when board space permits larger package and AOI is not required |
| MMSZ4686T1G | 10 V ±5%, SOD-123 package (3.7 × 1.6 × 1.1 mm), 500 mW PD, 30 Ω ZZT | Higher power rating but 3× larger area; lacks wettable flank and AEC-Q101 path | Select when thermal headroom is critical and AOI capability is secondary |

FAQ
What is the Zener voltage tolerance of NZ8F10VMX2WT5G?
The NZ8F10VMX2WT5G has a Zener voltage tolerance of ±5%, specified as 9.50 V minimum to 10.50 V maximum at test current IZT = 5 mA. This standard tolerance series (denoted by "M" in the part number) balances cost and precision for general-purpose regulation tasks where tight voltage stability is not mission-critical.
Is NZ8F10VMX2WT5G qualified for automotive use?
The NZ8F10VMX2WT5G itself is not AEC-Q101 qualified, but its SZ-prefix variant SZNZ8F10VMX2WT5G is fully AEC-Q101 qualified and PPAP capable. The base part shares identical electrical and mechanical specifications, enabling drop-in qualification readiness when automotive-grade traceability and change control are required.
What is the maximum reverse leakage current for NZ8F10VMX2WT5G?
The maximum reverse leakage current for NZ8F10VMX2WT5G is 0.1 µA at VR = 7 V and TA = 25 °C. This ultra-low leakage supports extended battery life in always-on portable devices and ensures minimal error contribution in precision reference applications.
Does NZ8F10VMX2WT5G have wettable flank terminals?
Yes, NZ8F10VMX2WT5G features wettable flank terminals in its X2DFNW2 package. The side-wall metallization extends down the package edge to enable full-surface solder fillet formation, allowing 100% automated optical inspection (AOI) without requiring X-ray verification-critical for high-reliability automotive and medical manufacturing.
What is the thermal resistance (RJA) of NZ8F10VMX2WT5G on a standard FR-4 board?
The thermal resistance (RJA) of NZ8F10VMX2WT5G is 415 °C/W when mounted on an FR-4 board with minimum pad size and 1 oz. copper. This value assumes worst-case thermal conduction and guides derating calculations: power dissipation must be reduced by 1.5 mW per °C above 25 °C ambient.
