Product details
Overview
SZNZ8F5V6MX2WT5G from onsemi is a 5.6 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, 0.40 mm body height, and AEC-Q101 qualified for automotive voltage regulation and ESD protection in space-constrained modules.
For engineers reviewing the SZNZ8F5V6MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), dynamic impedance (60 Ω @ 5 mA), leakage current (1 µA @ 2.5 V), capacitance (115 pF @ 0 V), and wettable flank compatibility with automated optical inspection in high-reliability PCB assembly.
Technical Context
This device operates as a unidirectional voltage reference and clamping element, leveraging silicon PN junction breakdown at reverse bias. Its low-profile X2DFNW2 package enables placement adjacent to IC power pins for local rail stabilization without increasing board area.
The SZNZ8F5V6MX2WT5G exhibits a nominal temperature coefficient of +9 mV/°C (typical) over −55 °C to +150 °C, with forward voltage ≤0.9 V at 10 mA, and is characterized for stable regulation under transient load conditions up to 40 W non-repetitive peak reverse power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.32–5.88 V @ IZT = 5 mA - defines regulated output range for 5.6 V nominal rail clamping |
| Zener Impedance (ZZT) | 60 Ω max @ IZT = 5 mA - determines voltage deviation under load current variation |
| Reverse Leakage (IR) | 1 µA max @ VR = 2.5 V - ensures minimal standby current in always-on circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NZ8F5V6MX2WT5G | No SZ prefix; not AEC-Q101 qualified; same electrical specs and package | Targeted for commercial-grade portable electronics, not automotive | Select when AEC-Q101 qualification and PPAP documentation are not required |
| SZNZ8F5V6SMX2WT5G | Tighter ±2.5% tolerance (5.47–5.73 V); otherwise identical package and qualification | Used where tighter reference accuracy is needed for precision analog sensing or feedback loops | Choose when VZ stability beyond ±5% is mandatory, accepting higher cost |
Compared with NZ8F5V6MX2WT5G, the SZNZ8F5V6MX2WT5G adds AEC-Q101 qualification and site control for automotive use, while SZNZ8F5V6SMX2WT5G improves voltage tolerance at the expense of broader VZ spread-enabling trade-offs between reliability assurance, accuracy, and cost in system-level BOM optimization.

FAQ
What is the Zener voltage tolerance of SZNZ8F5V6MX2WT5G?
The SZNZ8F5V6MX2WT5G has a Zener voltage tolerance of ±5%, specifying a minimum VZ of 5.32 V and maximum of 5.88 V at test current IZT = 5 mA. This tolerance band is defined per the standard tolerance series (MX2W) and applies across the full operating temperature range of −65 °C to +150 °C, as confirmed in the Electrical Characteristics table on page 2 of the onsemi datasheet.
Is SZNZ8F5V6MX2WT5G qualified for automotive applications?
Yes, SZNZ8F5V6MX2WT5G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the datasheet's Specification Features section. The "SZ" prefix denotes compliance with automotive-specific site and process control requirements, making it suitable for engine control units, ADAS modules, and other automotive subsystems requiring certified reliability.
What is the maximum power dissipation rating for SZNZ8F5V6MX2WT5G?
SZNZ8F5V6MX2WT5G is rated for 250 mW total device dissipation on FR-4 board with 1 oz. Cu and minimum pad layout at TA = 25 °C, derating linearly at 1.5 mW/°C above that temperature. This rating assumes the standard thermal test condition (Note 1) and is distinct from the 500 mW rating applicable to larger pad layouts (Note 2).
Does SZNZ8F5V6MX2WT5G have wettable flank packaging?
Yes, SZNZ8F5V6MX2WT5G uses the X2DFNW2 package with wettable flank geometry, as confirmed in the datasheet's "Specification Features" and "Mechanical Case Outline" sections. This feature enables high-accuracy automated optical inspection (AOI) of solder joints without requiring X-ray, supporting zero-defect manufacturing in automotive and medical production lines.
What is the reverse leakage current specification for SZNZ8F5V6MX2WT5G?
The reverse leakage current for SZNZ8F5V6MX2WT5G is specified as 1 µA maximum at VR = 2.5 V, per the Electrical Characteristics table on page 2. This value reflects worst-case leakage under sub-breakdown bias and is critical for low-power applications such as battery-backed sensor nodes where standby current must remain below 10 µA.
