Product details
Overview
SZNZ8F5V6SMX2WT5G from onsemi is an AEC-Q101-qualified Zener diode in X2DFNW2 (0402) wettable flank package, providing 5.47 V to 5.73 V nominal Zener voltage at 5 mA test current, 60 Ω maximum dynamic impedance, and 1 µA reverse leakage at 2.5 V, used for precision voltage regulation and ESD protection in automotive control units and portable electronics.
For engineers reviewing the SZNZ8F5V6SMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include tight ±2% Zener tolerance, 250 mW power dissipation on FR-4 with 1 oz. Cu minimum pad, low 0.40 mm body height, AOI-compatible wettable flanks, and automotive-grade qualification per AEC-Q101.
Technical Context
This device operates as a unidirectional voltage reference diode, conducting in reverse bias above its specified Zener breakdown voltage while maintaining stable clamping under transient overvoltage conditions. Its electrical behavior is defined at 5 mA test current (IZT), with temperature coefficient of VZ specified across −65 °C to +150 °C junction range.
The X2DFNW2 package enables high-density PCB layouts and automated optical inspection due to its wettable flank geometry and 0.65 mm pitch. Thermal performance is characterized by 415 °C/W junction-to-ambient resistance on minimal FR-4 pad layout, derating linearly above 25 °C ambient.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6LT1G | ±5% tolerance, SOT-23 package (3.0 mm × 1.4 mm), 350 mW PD, 40 Ω ZZT | Larger footprint, higher power handling, less suitable for ultra-dense automotive PCBs | Select when higher surge energy absorption is required and board space permits larger package |
| MMSZ5232BS-7-F | ±5% tolerance, SOD-123 package (3.7 mm × 1.6 mm), 500 mW PD, 17 Ω ZZT | Lower impedance but no AEC-Q101 qualification; not approved for automotive use | Select for industrial non-automotive applications where tighter ZZT matters more than qualification status |
Compared with BZX84-C5V6LT1G and MMSZ5232BS-7-F, SZNZ8F5V6SMX2WT5G offers superior automotive qualification, smallest footprint, and tighter tolerance-making it optimal for space-constrained, safety-critical vehicle subsystems despite slightly higher ZZT.

FAQ
What is the Zener voltage tolerance of SZNZ8F5V6SMX2WT5G?
SZNZ8F5V6SMX2WT5G has a tight ±2% Zener voltage tolerance, with a specified range of 5.47 V to 5.73 V at 5 mA test current. This tighter tolerance compared to standard-series Zeners (±5%) enables more precise voltage clamping in safety-critical automotive and industrial circuits without requiring external calibration or trimming.
Is SZNZ8F5V6SMX2WT5G qualified for automotive applications?
Yes, SZNZ8F5V6SMX2WT5G is AEC-Q101 qualified and PPAP capable, with the "SZ" prefix indicating compliance for automotive and other applications requiring unique site and process controls. It is rated for junction temperatures from −65 °C to +150 °C and validated for reliability under automotive stress conditions including thermal cycling and humidity testing.
What package type does SZNZ8F5V6SMX2WT5G use, and why is it significant?
SZNZ8F5V6SMX2WT5G uses the X2DFNW2 (Case 711BG) package-a 0402-sized, wettable flank, 2-terminal surface-mount device measuring 1.00 mm × 0.60 mm × 0.37 mm. Its wettable flanks enable reliable automated optical inspection of solder joints, critical for high-yield manufacturing in automotive electronics where zero-defect assembly is mandatory.
How much power can SZNZ8F5V6SMX2WT5G dissipate under standard PCB conditions?
SZNZ8F5V6SMX2WT5G dissipates up to 250 mW at 25 °C ambient on an FR-4 board with minimum pad layout (1 oz. Cu). Power derates linearly at 1.5 mW/°C above 25 °C. For enhanced thermal performance, a 150 mm² copper area raises the rating to 500 mW, supporting higher-energy transient suppression in industrial applications.
Does SZNZ8F5V6SMX2WT5G have RoHS and halogen-free compliance?
Yes, SZNZ8F5V6SMX2WT5G is Pb-Free, Halogen Free/BFR Free, and fully RoHS compliant per EU Directive 2011/65/EU. The "G" suffix in the part number explicitly denotes lead-free packaging, and material declarations confirm absence of restricted substances including cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE).
