Product details
Overview
NZ8F3V6SMX2WT5G from onsemi is a tight-tolerance Zener diode designed for precision voltage regulation and overvoltage protection in space-constrained PCB layouts. It delivers a nominal Zener voltage of 3.6 V (min 3.42 V, max 3.78 V) at 5 mA test current, with 100 Ω dynamic impedance, 10 nA leakage at 1 V reverse bias, and 210 pF capacitance at 0 V/1 MHz - deployed in automotive control units, handheld portables, and cellular phone power rails.
For engineers reviewing the NZ8F3V6SMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include ±2.5% Zener voltage tolerance, wettable flank X2DFNW2 (0402) package for AOI compatibility, 250 mW power dissipation on FR-4 with 1 oz. Cu minimum pad, AEC-Q101 qualification, and RoHS/Pb-free compliance.
Technical Context
This device operates as a unidirectional, silicon planar Zener diode optimized for low-profile, high-reliability voltage clamping. Its electrical behavior is defined by sharp reverse breakdown at precisely controlled VZ, low dynamic impedance (ZZT ≤ 100 Ω), and minimal temperature coefficient (typical +4 mV/°C near 3.6 V).
The X2DFNW2 package enables automated optical inspection via wettable flanks and supports reflow soldering per J-STD-020. Thermal performance is rated at 415 °C/W junction-to-ambient (FR-4 minimum pad) and −65 °C to +150 °C operating range, meeting automotive-grade reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.42 V to 3.78 V @ IZT = 5 mA - ensures stable 3.6 V reference with ±2.5% tolerance for precision biasing |
| Power Dissipation (PD) | 250 mW @ TA = 25 °C (FR-4, 1 oz. Cu min pad) - defines maximum continuous clamping energy without derating |
| Zener Impedance (ZZT) | ≤100 Ω @ IZT = 5 mA - maintains regulation accuracy under dynamic load transients |
| Reverse Leakage (IR) | ≤10 nA @ VR = 1 V - minimizes quiescent current loss in battery-powered systems |
| Capacitance (C) | 210 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and signal integrity in RF-adjacent circuits |
| Package | X2DFNW2 (0402, 1.00 × 0.60 × 0.37 mm) - enables ultra-compact placement and AOI-compatible wettable flanks |
| Qualification | AEC-Q101 qualified - validated for automotive electronics including engine control and body modules |
Pinout & Package
The NZ8F3V6SMX2WT5G uses the X2DFNW2 surface-mount package (Case 711BG), measuring 1.00 mm × 0.60 mm × 0.37 mm with wettable flank geometry for reliable solder joint inspection. It features two terminals in a standard anode–cathode configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode | Connected to higher-potential rail during reverse-bias operation; carries clamping current during overvoltage events |

Key Features
| Feature | Design Value |
|---|---|
| Tight Zener voltage tolerance | ±2.5% (3.42 V–3.78 V) enables accurate voltage reference without post-production trimming |
| Wettable flank package | X2DFNW2 geometry supports automated optical inspection of solder fillets, improving manufacturing yield in high-volume SMT lines |
| AEC-Q101 qualification | Validated for automotive applications including under-hood ECUs and infotainment power domains |
| Pb-free, Halogen-free, RoHS-compliant | Meets global environmental regulations and eliminates hazardous substances in final assembly |
| Low profile height | 0.37 mm max height allows stacking beneath shields or in multi-layer flex assemblies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V6LT1G | Standard tolerance (±5%), SOT-23 package (1.3 × 1.3 × 0.95 mm), 300 mW PD | Larger footprint, higher power, less precise VZ - suitable where space is less constrained and tighter regulation not required | Select for cost-sensitive industrial designs needing higher dissipation but tolerating looser voltage accuracy |
| MMSZ4685T1G | Tight tolerance (±2.5%), SOD-123 package (1.8 × 1.4 × 1.0 mm), 500 mW PD | Higher power rating and larger size - better for sustained clamping but incompatible with 0402 layout | Choose when thermal margin is critical and board area permits SOD-123 placement |
Compared with BZX84-C3V6LT1G and MMSZ4685T1G, the NZ8F3V6SMX2WT5G offers the smallest footprint (X2DFNW2), automotive qualification, and wettable flanks - making it optimal for high-density, AOI-driven, and automotive-grade designs where space and process control are prioritized over raw power handling.

FAQ
What is the Zener voltage tolerance of NZ8F3V6SMX2WT5G?
The NZ8F3V6SMX2WT5G has a tight Zener voltage tolerance of ±2.5%, specified as 3.42 V minimum and 3.78 V maximum at IZT = 5 mA. This tighter tolerance compared to standard-series Zeners (e.g., NZ8F3V6MX2WT5G at ±5%) enables more accurate voltage clamping in precision power rails and reference circuits without calibration.
Is NZ8F3V6SMX2WT5G qualified for automotive applications?
Yes, NZ8F3V6SMX2WT5G is AEC-Q101 qualified and PPAP capable. It meets the stress testing and reliability requirements for automotive electronics, including operation across −65 °C to +150 °C junction temperature and validation for use in engine control units, body control modules, and infotainment power domains.
What package type does NZ8F3V6SMX2WT5G use, and why is it significant?
NZ8F3V6SMX2WT5G uses the X2DFNW2 (Case 711BG) package - a 0402-sized, wettable flank, leadless DFN. Its significance lies in enabling automated optical inspection of solder joints, supporting high-yield SMT assembly, and delivering the smallest possible footprint (1.00 × 0.60 × 0.37 mm) for ultra-dense PCBs in portable and automotive systems.
How does the power dissipation rating of NZ8F3V6SMX2WT5G vary with PCB layout?
NZ8F3V6SMX2WT5G has two power ratings: 250 mW on FR-4 with minimum pad (1 oz. Cu), derating at 1.5 mW/°C above 25 °C; and 500 mW on FR-4 with 150 mm² copper area (1 oz. Cu), derating at 1.2 mW/°C. Layout directly impacts thermal resistance - smaller pads increase RJA to 415 °C/W, while larger copper areas reduce it to 247 °C/W.
What is the reverse leakage current specification for NZ8F3V6SMX2WT5G?
The reverse leakage current for NZ8F3V6SMX2WT5G is rated at ≤10 nA at VR = 1 V and TA = 25 °C. This ultra-low leakage supports extended battery life in always-on portable devices and prevents unintended discharge paths in high-impedance sensor bias networks.
