Product details
Overview
NZ8F7V5MX2WT5G from onsemi is a 7.5 V ±4% 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 and 150 mm² pad area, designed for precision voltage regulation and ESD-sensitive signal line protection in space-constrained portable electronics.
For engineers reviewing the NZ8F7V5MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 7.13–7.88 V Zener voltage range at 5 mA test current, 30 Ω dynamic impedance, 0.5 µA leakage at 4 V reverse bias, 100 pF capacitance at 0 V/1 MHz, and AEC-Q101 qualification when ordered with SZ prefix.
Technical Context
This device operates as a unidirectional voltage reference diode, conducting in reverse breakdown to clamp transient overvoltage and stabilize bias points. Its low 0.40 mm body height and wettable flank geometry support AOI-compatible automated assembly and high-density PCB layouts.
The NZ8F7V5MX2WT5G exhibits a nominal temperature coefficient of +4 mV/°C across −55 °C to +150 °C, enabling stable regulation in automotive and industrial environments. It delivers 0.9 V forward voltage maximum at 10 mA, with thermal resistance of 247 °C/W under optimized pad conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C7V5 | 7.5 V ±5%, SOD-523 package (1.2 × 0.8 × 0.6 mm), 200 mW rating, no wettable flank | Larger footprint and higher thermal resistance (350 °C/W); unsuitable for AOI-dependent high-volume production | Select when cost sensitivity outweighs AOI capability and board space constraints |
| MMSZ5236B | 7.5 V ±5%, SOD-123 package (3.7 × 1.6 × 1.1 mm), 500 mW rating, standard gull-wing leads | 3× larger area; incompatible with 0402 placement equipment; better for manual repair or low-volume prototyping | Select when higher power handling (>300 mW) is required and layout density is not constrained |
Compared with BZX584C7V5 and MMSZ5236B, the NZ8F7V5MX2WT5G offers superior AOI compatibility, smallest PCB footprint, and tighter thermal performance in high-density automated assembly-making it optimal for mass-produced portable and automotive electronics where space, inspection yield, and thermal management are critical.

FAQ
What is the Zener voltage tolerance of NZ8F7V5MX2WT5G?
The NZ8F7V5MX2WT5G has a standard tolerance of ±4%, resulting in a guaranteed Zener voltage range of 7.13 V to 7.88 V at 5 mA test current. This tolerance is specified in the Electrical Characteristics table on page 2 of the official onsemi datasheet and applies strictly to the NZ8FxxxMX2WT5G series, distinguishing it from the tighter ±1.5% tolerance of the NZ8FxxxSMX2WT5G variant. The NZ8F7V5MX2WT5G maintains this specification across its full operating temperature range.
Is NZ8F7V5MX2WT5G qualified for automotive applications?
The base NZ8F7V5MX2WT5G is not automatically automotive-qualified; however, the SZ-prefixed version SZNZ8F7V5MX2WT5G is AEC-Q101 qualified and PPAP capable. This qualification requires specific manufacturing site controls and change management protocols documented in onsemi's PPAP submissions. For automotive body control or infotainment modules, designers must specify the SZ prefix to ensure compliance with automotive reliability and traceability requirements.
What is the maximum power dissipation of NZ8F7V5MX2WT5G on a standard PCB?
NZ8F7V5MX2WT5G delivers 250 mW maximum power dissipation at 25 °C ambient when mounted on an FR-4 board with minimum pad size and 1 oz. copper, derating linearly by 1.5 mW/°C above that temperature. With an optimized 150 mm² pad and 1 oz. copper, it achieves 500 mW at 25 °C, derating by 1.2 mW/°C. These values are explicitly defined in the Maximum Ratings table on page 1 of the datasheet and reflect real-world thermal performance under two distinct PCB layout conditions.
Does NZ8F7V5MX2WT5G support automated optical inspection (AOI)?
Yes, NZ8F7V5MX2WT5G features a wettable flank package (X2DFNW2) specifically designed for high-yield AOI. The side-wall metallization extends below the package body to form visible, reflective solder fillets during reflow, enabling reliable machine vision detection of solder joint quality without requiring X-ray inspection. This capability is highlighted in the Specification Features section and confirmed in the Mechanical Case Outline drawing on page 6 of the datasheet.
What is the reverse leakage current specification for NZ8F7V5MX2WT5G?
NZ8F7V5MX2WT5G specifies a maximum reverse leakage current (IR) of 0.5 µA at VR = 4 V, measured at 25 °C. This value is confirmed in the Electrical Characteristics table on page 2 and reflects the device's suitability for low-power, battery-operated applications such as wearables and wireless sensors where standby current must remain sub-microampere. Leakage remains within specification across the full −65 °C to +150 °C storage temperature range.
