Product details
Overview
SZNZ8F2V7MX2WT5G from onsemi is a 2.43–2.97 V, ±5% tolerance Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C on FR-4 board, with 210 pF capacitance and 100 Ω dynamic impedance at 5 mA, used for precision voltage clamping in space-constrained automotive control units.
For engineers reviewing the SZNZ8F2V7MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q101 qualification, wettable flank geometry for AOI compatibility, tight thermal resistance (415 °C/W), low leakage (20 µA @ 1 V), and automotive-grade traceability under PPAP.
Technical Context
This device operates as a unidirectional Zener regulator with reverse-biased breakdown behavior, specified at IZT = 5 mA and tested across −65 °C to +150 °C junction temperature range. Its low 0.40 mm body height and 1.00 × 0.60 mm footprint support high-density PCB layouts in portable and automotive electronics.
The SZNZ8F2V7MX2WT5G features a nominal temperature coefficient of +9 mV/°C (typical), exhibits <0.9 V forward voltage at 10 mA, and maintains stable regulation under transient conditions with non-repetitive peak reverse power capability of 40 W for 100 µs pulses.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NZ8F2V7MX2WT5G | No SZ prefix; not AEC-Q101 qualified or PPAP capable; same electrical specs and package | Restricted to commercial-grade applications without automotive traceability requirements | Select when AEC-Q101 compliance is unnecessary and cost sensitivity outweighs process control needs |
| SZNZ8F2V7SMX2WT5G | Tighter ±3% Zener tolerance (2.54–2.86 V); otherwise identical package, ratings, and qualification | Better suited for precision reference circuits where tighter voltage window reduces calibration overhead | Choose when system-level voltage margin is <0.2 V and production calibration time must be minimized |
Compared with NZ8F2V7MX2WT5G, the SZNZ8F2V7MX2WT5G adds AEC-Q101 qualification and PPAP support without sacrificing electrical performance; versus SZNZ8F2V7SMX2WT5G, it trades tighter tolerance for broader voltage margin-ideal for general-purpose clamping where robustness matters more than precision.

FAQ
What is the Zener voltage tolerance of SZNZ8F2V7MX2WT5G?
The SZNZ8F2V7MX2WT5G has a Zener voltage tolerance of ±5%, with a specified breakdown range of 2.43 V to 2.97 V at test current IZT = 5 mA. This tolerance is confirmed in the Electrical Characteristics table on page 2 of the official onsemi datasheet (Rev. 4, November 2025). The SZNZ8F2V7MX2WT5G is part of the standard-tolerance NZ8FxxxMX2W series, distinct from the tighter ±3% S-series variants.
Is SZNZ8F2V7MX2WT5G qualified for automotive use?
Yes, the SZNZ8F2V7MX2WT5G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the datasheet's Specification Features section and reinforced by the "SZ" prefix designation. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, making the SZNZ8F2V7MX2WT5G suitable for under-hood and cabin automotive control units requiring full automotive process controls.
What package type does SZNZ8F2V7MX2WT5G use, and why is it significant?
The SZNZ8F2V7MX2WT5G uses the X2DFNW2 package-a 0402-inch (1.00 × 0.60 × 0.37 mm), wettable flank, leadless DFN variant. Its significance lies in enabling reliable automated optical inspection (AOI) of solder joints without X-ray, critical for high-volume automotive PCB assembly. The package also delivers low thermal resistance (415 °C/W) and fits tight pitch layouts where traditional SOD-323 or SOD-523 packages cannot be placed.
What is the maximum power dissipation rating for SZNZ8F2V7MX2WT5G?
The SZNZ8F2V7MX2WT5G is rated for 250 mW total device dissipation at TA = 25 °C on an FR-4 board with minimum pad layout (1 oz Cu), derating linearly at 1.5 mW/°C above that temperature. This rating is defined in the Maximum Ratings table (Note 1) of the datasheet and applies to continuous DC operation-not transient pulse conditions, where the non-repetitive peak reverse power limit of 40 W (100 µs) governs.
How does the capacitance of SZNZ8F2V7MX2WT5G affect high-frequency circuit design?
The SZNZ8F2V7MX2WT5G exhibits 210 pF capacitance at 0 V bias and 1 MHz, which can load high-speed signal paths or degrade RF immunity if placed near sensitive analog inputs. In practice, this value makes the SZNZ8F2V7MX2WT5G appropriate for clamping low-to-moderate frequency transients (e.g., load dump, ESD) but less ideal for GHz-range EMI suppression-where lower-capacitance TVS diodes would be preferred. Layout best practices require minimizing trace length to preserve its effectiveness.
