Product details
Overview
NZ8F22VSMX2WT5G from onsemi is a tight-tolerance Zener diode with nominal breakdown voltage of 22.0 V (21.49 V min / 22.51 V max), 5 mA test current, and 55 Ω dynamic impedance at IZT, packaged in the X2DFNW2 wettable flank 0402 footprint for high-reliability voltage regulation in space-constrained automotive control units.
For engineers reviewing the NZ8F22VSMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include ±2.3% Zener tolerance, 0.40 mm body height, AEC-Q101 qualification, 16.8 V forward voltage limit at 10 mA, and 55 pF capacitance at 0 V bias - all critical for ESD-protected power rail clamping and precision reference design.
Technical Context
This device operates as a unidirectional voltage regulator in reverse-biased mode, with Zener breakdown specified at IZT = 5 mA and thermal derating of 1.2 mW/°C above 25 °C on FR-4 board (150 mm² copper). Its low 0.40 mm profile and wettable flank geometry support automated optical inspection and fine-pitch reflow in automotive PCB assemblies.
The NZ8F22VSMX2WT5G exhibits a temperature coefficient of approximately +7 mV/°C near 22 V (per typical TC curves), leakage current ≤0.1 µA at 16.8 V reverse bias, and junction-to-ambient thermal resistance of 247 °C/W under optimized pad layout - enabling stable regulation across −65 °C to +150 °C ambient range.

What package type does NZ8F22VSMX2WT5G use, and why is it significant?
NZ8F22VSMX2WT5G uses the X2DFNW2 package (Case 711BG), a 0402-sized wettable flank leadless device measuring 1.00 mm × 0.60 mm × 0.37 mm. The wettable flank design enables reliable automated optical inspection of solder joints - a critical requirement for zero-defect manufacturing in automotive PCB assembly, distinguishing the NZ8F22VSMX2WT5G from conventional 0402 diodes.
What is the maximum power dissipation rating for NZ8F22VSMX2WT5G?
The NZ8F22VSMX2WT5G has a maximum power dissipation of 500 mW at TA = 25 °C when mounted on an FR-4 board with 150 mm² of 1 oz. copper. It derates linearly at 1.2 mW/°C above 25 °C, supporting sustained operation up to +150 °C junction temperature - essential for thermal resilience in engine-control and powertrain applications using the NZ8F22VSMX2WT5G.
