Product details
Overview
NZ8F10VSMX2WT5G from onsemi is a tight-tolerance Zener diode optimized for precision voltage regulation and transient overvoltage clamping in space-constrained PCBs. It delivers a nominal Zener voltage of 10.0 V (9.77–10.23 V at IZT = 5 mA), with 30 Ω dynamic impedance, 0.1 µA reverse leakage at 7 V, and 80 pF capacitance at 0 V bias - enabling stable reference and ESD-sensitive signal-line protection in automotive control units and portable power rails.
For engineers reviewing the NZ8F10VSMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, wettable flank X2DFNW2 package for AOI compatibility, ±2.3% voltage tolerance, and thermal resistance of 247 °C/W on 150 mm² FR-4 board - critical for high-reliability embedded voltage monitoring and clamp design.
Technical Context
This device operates as a unidirectional, silicon planar Zener diode with sharp reverse breakdown characteristics. Its electrical behavior is defined at IZT = 5 mA, with temperature coefficient of ±4 mV/°C across −55 °C to +150 °C and forward voltage ≤0.9 V at 10 mA.
The NZ8F10VSMX2WT5G is rated for 500 mW total dissipation on a 150 mm² FR-4 board (derating 1.2 mW/°C above 25 °C) and supports non-repetitive peak reverse power up to 40 W for transient suppression. It is Pb-free, halogen-free/BFR-free, and RoHS compliant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.77–10.23 V @ IZT = 5 mA - ensures ±2.3% regulation accuracy for precision reference circuits |
| Zener Impedance (ZZT) | 30 Ω @ IZT = 5 mA - maintains low output impedance under load variation for stable clamping |
| Reverse Leakage (IR) | 0.1 µA @ VR = 7 V - minimizes standby current in battery-powered systems |
| Capacitance (C) | 80 pF @ VR = 0 V, f = 1 MHz - suitable for low-speed signal line protection without signal distortion |
| Power Dissipation (PD) | 500 mW @ TA = 25 °C (150 mm² pad) - enables robust operation in thermally demanding automotive environments |
| Thermal Resistance (RJA) | 247 °C/W - allows predictable junction temperature rise for reliability modeling |
| Junction Temp Range | −65 °C to +150 °C - supports operation in under-hood automotive and industrial ambient conditions |
Pinout & Package
The NZ8F10VSMX2WT5G is housed in the X2DFNW2 surface-mount package (Case 711BG), measuring 1.00 × 0.60 × 0.37 mm with 0.65 mm pitch and wettable flank side walls for automated optical inspection. The package features two terminals: Cathode (Pin 1) and Anode (Pin 2), marked per device-specific code "CT" on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NZ8F10VMX2WT5G | Standard tolerance (±5%): 9.5–10.5 V vs. NZ8F10VSMX2WT5G's ±2.3% | Suitable for non-critical biasing where tighter regulation is not required | Select when cost sensitivity outweighs voltage accuracy needs; same package and thermal specs |
| BZX84-C10LT1G | Higher ZZT (40 Ω), wider tolerance (±5%), larger SOT-23 package (1.3 × 0.9 mm) | Limited to less space-constrained consumer-grade designs; no AEC-Q101 or wettable flank | Choose only if legacy SOT-23 layout exists and automotive qualification is unnecessary |
Compared with NZ8F10VMX2WT5G and BZX84-C10LT1G, the NZ8F10VSMX2WT5G provides superior voltage accuracy and manufacturability for high-volume automotive and medical designs - but requires revalidation of AOI algorithms and thermal pad layout due to its X2DFNW2 footprint.

FAQ
What is the Zener voltage tolerance of NZ8F10VSMX2WT5G?
The NZ8F10VSMX2WT5G has a tight Zener voltage tolerance of ±2.3%, specified as 9.77 V minimum to 10.23 V maximum at test current IZT = 5 mA. This tighter tolerance versus the standard NZ8F10VMX2WT5G (±5%) makes NZ8F10VSMX2WT5G appropriate for precision reference and feedback applications where voltage stability is critical across temperature and aging.
Is NZ8F10VSMX2WT5G qualified for automotive use?
Yes, NZ8F10VSMX2WT5G is AEC-Q101 qualified and PPAP capable. It undergoes rigorous stress testing including temperature cycling, high-temperature operating life, and mechanical shock per the AEC-Q101 standard. The "SZ" prefix variant (SZNZ8F10VSMX2WT5G) is explicitly designated for automotive applications requiring unique site and control change tracking.
What package type does NZ8F10VSMX2WT5G use, and why is it significant?
NZ8F10VSMX2WT5G uses the X2DFNW2 package (Case 711BG), a 0402-sized wettable flank leadless package measuring 1.00 × 0.60 × 0.37 mm. Its wettable flanks enable full-surface solder joint inspection via automated optical inspection (AOI), improving manufacturing yield and field reliability - especially important for safety-critical automotive and medical PCB assemblies.
How does the thermal performance of NZ8F10VSMX2WT5G compare between different PCB layouts?
NZ8F10VSMX2WT5G offers two thermal ratings: 415 °C/W on minimal FR-4 pads (1 oz. Cu), and 247 °C/W on optimized 150 mm² pads (1 oz. Cu). This 40% improvement in thermal resistance enables 500 mW continuous dissipation instead of 250 mW - making pad layout a decisive factor in power handling and long-term reliability for sustained clamp operation.
Can NZ8F10VSMX2WT5G replace NZ8F10VMX2WT5G in an existing design?
NZ8F10VSMX2WT5G is a direct functional upgrade to NZ8F10VMX2WT5G with identical X2DFNW2 package, pinout, and thermal characteristics - but tighter voltage tolerance (±2.3% vs. ±5%). No PCB changes are needed; however, system-level validation of reference accuracy and loop stability is recommended due to improved regulation performance.
