Product details
Overview
NZ8F15VMX2WT5G from onsemi is a 15 V ±5% standard-tolerance Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C on FR-4 board with 1 oz. Cu, 0.40 mm body height, and 70 pF capacitance at 0 V/1 MHz - used for precision voltage clamping in space-constrained power rails of automotive control units and portable electronics.
For engineers reviewing the NZ8F15VMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), low-profile wettable flank package for AOI compatibility, AEC-Q101 qualification status, thermal derating slope (1.5 mW/°C), and leakage current ≤0.1 µA at 11 V reverse bias.
Technical Context
This device operates as a unidirectional voltage reference diode, conducting in reverse breakdown at nominal 15 V with 5 mA test current (IZT), exhibiting 42 Ω dynamic impedance (ZZT) and temperature coefficient of +9 mV/°C. It maintains stable regulation across −65 °C to +150 °C junction temperature range.
The X2DFNW2 package features solderable side walls enabling automated optical inspection, and its 1.00 mm × 0.60 mm footprint supports high-density PCB layouts. Thermal resistance is 415 °C/W (Junction-to-Ambient, minimum pad), limiting continuous power handling under elevated ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.25 V to 15.75 V @ IZT = 5 mA - defines clamping threshold with ±5% tolerance for stable overvoltage protection |
| Power Dissipation (PD) | 250 mW @ TA = 25 °C - sets maximum steady-state energy handling on standard FR-4 board |
| Zener Impedance (ZZT) | 42 Ω @ IZT = 5 mA - determines regulation stiffness and output voltage variation under load changes |
| Reverse Leakage (IR) | ≤0.1 µA @ VR = 11 V - ensures minimal standby current in high-impedance bias networks |
| Capacitance (C) | 70 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and signal integrity in RF-adjacent circuits |
| Package | X2DFNW2 (0402, 1.00 mm × 0.60 mm × 0.37 mm) - enables AOI-compatible, ultra-compact mounting in portable and automotive PCBs |
| Thermal Resistance (RJA) | 415 °C/W - dictates required board copper area and airflow for safe operation above 25 °C ambient |
Pinout & Package
The NZ8F15VMX2WT5G uses the X2DFNW2 surface-mount package (Case 711BG), measuring 1.00 mm × 0.60 mm × 0.37 mm with wettable flank sidewalls for reliable solder joint inspection. Its low 0.40 mm profile minimizes board stack height in thin-form-factor designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to regulated voltage rail; reverse-biased to conduct at 15 V, providing clamping reference |
| 2 (Anode) | Reference ground return | Tied to system ground or lower-potential node; completes Zener conduction path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 standards |
| Wettable flank package | Enables 100% automated optical inspection of solder fillets without X-ray, reducing post-reflow defect escape |
| Pb-Free, Halogen Free/BFR Free | Complies with RoHS Directive 2011/65/EU and JEDEC JS709E, supporting green manufacturing requirements |
| Low 0.40 mm body height | Reduces mechanical interference in stacked modules and allows placement beneath low-clearance shields or connectors |
Applications
| Automotive Engine Control Unit (ECU) Power Rail Protection | Smartphone Battery Management IC Reference Clamp |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15LT1G | Same 15 V nominal, ±5% tolerance, but SOT-23 package (3.0 mm × 1.4 mm); 350 mW PD; 90 Ω ZZT | Larger footprint and higher thermal resistance (350 °C/W); unsuitable for 0402-constrained layouts | Select when higher power margin is needed and board space permits larger package |
| NZ8F15VSMX2WT5G | Tight-tolerance variant: 14.66–15.35 V (±2.3%); identical X2DFNW2 package and electrical specs otherwise | Used where tighter regulation is required - e.g., precision ADC reference buffers or feedback loops demanding <1% error | Choose for improved voltage accuracy without layout change; same solder profile and AOI compatibility |
Compared with BZX84-C15LT1G and NZ8F15VSMX2WT5G, the NZ8F15VMX2WT5G balances compactness, automotive qualification, and cost-effective standard tolerance - making it optimal for volume automotive and portable applications where 15 V clamping with ±5% is sufficient and 0402 placement is mandatory.

Yes, NZ8F15VMX2WT5G is AEC-Q101 qualified and PPAP capable. The datasheet explicitly states that devices with the "SZ" prefix (e.g., SZNZ8F15VMX2WT5G) meet automotive requirements, and confirms that the base NZ8FxxxMX2WT5G series shares the same qualification - including stress testing for temperature cycling, HTRB, and ESD per JESD22 standards.
What is the maximum power dissipation for NZ8F15VMX2WT5G on a standard PCB?
NZ8F15VMX2WT5G is rated for 250 mW total device dissipation at TA = 25 °C on an FR-4 board with minimum pad and 1 oz. copper. It must be derated by 1.5 mW/°C above 25 °C ambient, based on a thermal resistance of 415 °C/W - confirmed in the Maximum Ratings table of the official onsemi datasheet.
Does NZ8F15VMX2WT5G have wettable flank terminals?
Yes, NZ8F15VMX2WT5G uses the X2DFNW2 package with wettable flank sidewalls, as stated in the datasheet's "Specification Features" section. This design enables full-surface solder joint inspection via automated optical inspection (AOI), eliminating the need for X-ray in high-volume manufacturing.
