Product details
Overview
NZ8F22VMX2WT5G from onsemi is a 22 V ±5% Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C on FR-4 board with 1 oz. Cu, featuring 55 Ω dynamic impedance at 5 mA test current and 0.1 µA leakage at 16.8 V reverse bias. It delivers precision voltage regulation in space-constrained power rail protection circuits.
For engineers reviewing the NZ8F22VMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), low-profile 0.40 mm height, AOI-compatible wettable flanks, AEC-Q101 qualification eligibility via SZ prefix, and 55 pF capacitance at 0 V - critical for ESD clamp stability in high-frequency signal lines.
Technical Context
This device operates as a unidirectional voltage reference and overvoltage clamp, leveraging silicon PN junction Zener breakdown at nominal 22 V. Its thermal resistance of 415 °C/W (FR-4, min pad) and derating slope of 1.5 mW/°C above 25 °C define safe operating limits under continuous DC stress.
The NZ8F22VMX2WT5G exhibits a typical temperature coefficient near +9 mV/°C (per Figure 4), confirming positive VZ drift with temperature - a key design factor when regulating rails exposed to automotive or industrial ambient swings from −65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 20.9 V to 23.1 V at IZT = 5 mA - defines clamping threshold range for 22 V nominal rail protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B22,115 (Nexperia) | Same 22 V nominal, ±5% tolerance, but SOD323 package (1.3 × 0.65 × 0.9 mm); 400 mW PD; 90 Ω ZZT @ 5 mA | Larger footprint and higher ZZT reduce suitability for ultra-dense 0402 layouts and low-noise analog rails | Select when higher power margin is required and board area allows SOD323 placement |
| MMSZ4686T1G (onsemi) | 22 V nominal, ±5%, SOD-123 package (2.7 × 1.4 × 1.0 mm); 500 mW PD; 35 Ω ZZT @ 5 mA; no wettable flanks | Higher power and lower impedance benefit high-current clamping, but larger size and non-AOI-optimized leads limit use in fine-pitch automated assembly | Prefer for industrial power supplies where thermal margin outweighs AOI and miniaturization needs |
Compared with BZX384-B22,115 and MMSZ4686T1G, the NZ8F22VMX2WT5G uniquely combines 0402 wettable flank geometry, 250 mW rating optimized for FR-4 min-pad layouts, and 55 Ω impedance - making it the only option qualified for both automotive AOI production and space-critical USB/PMIC protection.

What is the Zener voltage tolerance of NZ8F22VMX2WT5G?
The NZ8F22VMX2WT5G has a Zener voltage range of 20.9 V to 23.1 V at IZT = 5 mA, corresponding to a ±5% tolerance around the nominal 22 V rating. This tolerance is specified in the Electrical Characteristics table on page 2 of the onsemi datasheet and applies under standard test conditions (TA = 25 °C).
Does NZ8F22VMX2WT5G support automotive qualification?
The NZ8F22VMX2WT5G itself is not AEC-Q101 qualified, but its SZ-prefix variant (SZNZ8F22VMX2WT5G) is explicitly designated for automotive applications, meeting AEC-Q101 stress testing requirements and supporting PPAP documentation. The base NZ8F22VMX2WT5G shares identical electrical and mechanical specifications.
What is the maximum reverse leakage current for NZ8F22VMX2WT5G?
The maximum reverse leakage current for NZ8F22VMX2WT5G is 0.1 µA at VR = 16.8 V, as specified in the Electrical Characteristics table. This low leakage ensures minimal parasitic loading on sensitive 22 V reference or bias networks in battery-powered systems.
Can NZ8F22VMX2WT5G be used for ESD protection on high-speed data lines?
Yes - NZ8F22VMX2WT5G offers 55 pF capacitance at 0 V bias and 1 MHz, making it suitable for ESD protection on USB 2.0 (480 Mbps) and other moderate-speed digital interfaces. Its fast Zener response and low leakage preserve signal integrity without introducing excessive jitter or insertion loss.
What is the thermal resistance (RJA) of NZ8F22VMX2WT5G on a standard FR-4 board?
The junction-to-ambient thermal resistance (RJA) of NZ8F22VMX2WT5G is 415 °C/W when mounted on an FR-4 board with minimum pad layout and 1 oz. copper. This value is defined in the Maximum Ratings table and governs derating above 25 °C (1.5 mW/°C).
