Product details
Overview
SZNZ8F6V8MX2WT5G from onsemi is an AEC-Q101 qualified automotive-grade Zener diode in X2DFNW2 (0402) wettable flank package, delivering 6.46 V to 7.14 V reverse breakdown voltage at 5 mA test current, 40 Ω maximum dynamic impedance, and 0.5 µA leakage current at 3.5 V reverse bias - used for precision voltage clamping and ESD protection in space-constrained automotive control units.
For engineers reviewing the SZNZ8F6V8MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5% standard), thermal resistance (415 °C/W on FR-4 minimum pad), wettable flank compatibility with AOI, and AEC-Q101 qualification for under-hood electronics.
Technical Context
This device operates as a unidirectional voltage regulator with sharp reverse breakdown characteristics, optimized for low-profile PCB layouts where automated optical inspection (AOI) is required. Its X2DFNW2 package features solderable side flanks enabling reliable solder joint inspection and high-density placement.
The SZNZ8F6V8MX2WT5G exhibits a nominal temperature coefficient of +9 mV/°C (typical) and maintains stable regulation across −65 °C to +150 °C junction temperature range. It supports non-repetitive peak reverse power up to 40 W for transient suppression without derating below 25 °C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V8,115 (Nexperia) | Same 6.8 V nominal Zener, but ±5% tolerance only in tight-tolerance variants; 500 mW PD rating on larger SOD323 package | Higher power dissipation supports higher surge currents but requires 2.1 mm × 1.3 mm board area vs. 1.0 mm × 0.6 mm | Select when surge energy handling >250 mW is required and board space permits larger footprint |
| MMSZ4687T1G (onsemi) | 6.8 V Zener in SOD-123 package; ±5% tolerance; 500 mW rating; no AEC-Q101 qualification or wettable flank | Not qualified for automotive use; lacks AOI-compatible side flanks; suitable for industrial/commercial only | Select for cost-sensitive non-automotive designs where AEC-Q101 and AOI are not mandated |
Compared with BZX384-B6V8,115 and MMSZ4687T1G, the SZNZ8F6V8MX2WT5G uniquely combines AEC-Q101 qualification, wettable flank geometry, and 0402 size - making it the only option for space-constrained, AOI-verified, automotive-grade Zener clamping.

FAQ
What is the Zener voltage tolerance of SZNZ8F6V8MX2WT5G?
The SZNZ8F6V8MX2WT5G has a Zener voltage range of 6.46 V to 7.14 V at 5 mA test current, corresponding to ±5% tolerance around the nominal 6.8 V rating. This tolerance is specified per the NZ8FxxxMX2W standard series and is validated across −65 °C to +150 °C operating temperature range. The SZNZ8F6V8MX2WT5G does not use the tighter ±2% tolerance found in the SMX2W variant.
Is SZNZ8F6V8MX2WT5G qualified for automotive applications?
Yes, the SZNZ8F6V8MX2WT5G is AEC-Q101 qualified and PPAP capable, with the "SZ" prefix explicitly indicating compliance for automotive and other applications requiring unique site and process controls. It meets stress testing requirements including high-temperature reverse bias (HTRB), temperature cycling (TCT), and high-temperature gate bias (HTGB).
What is the maximum power dissipation for SZNZ8F6V8MX2WT5G on a standard FR-4 PCB?
The SZNZ8F6V8MX2WT5G delivers 250 mW total device dissipation on an FR-4 board with minimum pad layout (1 oz Cu), derating linearly by 1.5 mW/°C above 25 °C ambient. With enhanced copper area (150 mm², 1 oz Cu), its rating increases to 500 mW with 1.2 mW/°C derating - both values confirmed in the Absolute Maximum Ratings table of the official datasheet.
Does SZNZ8F6V8MX2WT5G support automated optical inspection (AOI)?
Yes, the SZNZ8F6V8MX2WT5G uses the X2DFNW2 package with wettable flank geometry, enabling full-surface solder joint inspection using standard AOI systems. This eliminates the need for X-ray verification in high-volume automotive assembly lines and is explicitly cited as a specification feature in the datasheet.
What is the forward voltage specification for SZNZ8F6V8MX2WT5G?
The SZNZ8F6V8MX2WT5G has a maximum forward voltage of 0.9 V at 10 mA forward current, consistent across all NZ8FxxxMX2W devices. This value is specified in the Electrical Characteristics summary table and applies under standard test conditions (TA = 25 °C), supporting accurate forward-bias modeling in crowbar or dual-diode protection schemes.
