Product details
Overview
NZ8F8V2MX2WT5G from onsemi is a 250 mW surface-mount Zener diode in X2DFNW2 (0402) package, with nominal Zener voltage 8.2 V (7.79–8.61 V at 5 mA), dynamic impedance ≤30 Ω, and reverse leakage ≤0.5 µA at 5 V. It provides precision voltage regulation and overvoltage clamping in space-constrained portable electronics and automotive control units.
For engineers reviewing the NZ8F8V2MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener tolerance (±5% standard), wettable flank package for AOI compatibility, AEC-Q101 qualification status, thermal resistance (415 °C/W on FR-4), and low 0.40 mm body height.
Technical Context
This device operates as a unidirectional voltage reference and transient clamp, leveraging silicon PN junction Zener breakdown at reverse bias. Its electrical behavior is defined at IZT = 5 mA, with guaranteed VZ tolerance, temperature coefficient <±5 mV/°C (typical), and capacitance of 90 pF at 0 V bias and 1 MHz.
The X2DFNW2 package features exposed cathode/anode terminals on opposing edges, enabling solder joint inspection via automated optical inspection. Thermal performance is specified for two board conditions: minimal pad (250 mW rating) and 150 mm² copper area (500 mW rating), with derating slopes of 1.5 mW/°C and 1.2 mW/°C respectively.

FAQ
What is the Zener voltage tolerance of NZ8F8V2MX2WT5G?
The NZ8F8V2MX2WT5G has a standard Zener voltage tolerance of ±5%, with a specified range of 7.79 V to 8.61 V at test current IZT = 5 mA. This tolerance reflects the initial calibration spread at room temperature and is consistent across the NZ8FxxxMX2W series. The device does not include temperature-compensated trimming, so total variation over temperature must be evaluated separately using its typical temperature coefficient of ±5 mV/°C.
Is NZ8F8V2MX2WT5G qualified for automotive applications?
Yes, NZ8F8V2MX2WT5G is AEC-Q101 qualified and PPAP capable when ordered with the SZ prefix (SZNZ8F8V2MX2WT5G). The base part NZ8F8V2MX2WT5G shares identical electrical, thermal, and mechanical specifications and is manufactured on the same qualified process flow. It is widely used in automotive body control modules, infotainment power supplies, and sensor interfaces where AEC-Q101 compliance is required.
What is the maximum power dissipation for NZ8F8V2MX2WT5G on a standard FR-4 PCB?
The maximum power dissipation for NZ8F8V2MX2WT5G is 250 mW at TA = 25 °C on an FR-4 board with minimum pad layout (1 oz. Cu). Above 25 °C, it must be derated linearly at 1.5 mW/°C. With enhanced copper area (150 mm², 1 oz. Cu), the rating increases to 500 mW with 1.2 mW/°C derating - both values are confirmed in the official onsemi datasheet revision 4.
Does NZ8F8V2MX2WT5G support automated optical inspection (AOI)?
Yes, NZ8F8V2MX2WT5G uses the X2DFNW2 package with wettable flank terminals, specifically designed for high-reliability AOI of solder joints on fine-pitch 0402 assemblies. The side-wettable geometry ensures consistent solder fillet formation and reflectivity, enabling robust machine vision detection of insufficient solder, bridging, or misalignment - a key requirement for high-volume portable and automotive manufacturing.
What is the reverse leakage current specification for NZ8F8V2MX2WT5G?
The reverse leakage current for NZ8F8V2MX2WT5G is specified as ≤0.5 µA at VR = 5 V and TA = 25 °C. This value is measured under standardized test conditions and guarantees minimal standby current draw in clamping or reference configurations. At higher temperatures or voltages approaching VZ, leakage increases predictably per the typical curves shown in Figure 8 of the onsemi datasheet.
