Product details
Overview
SZNZ8F16VMX2WT5G from onsemi is a 16 V ±5% Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C on FR-4 with 1 oz. Cu, 0.40 mm body height, and AEC-Q101 qualified for automotive voltage regulation and ESD protection in space-constrained systems.
For engineers reviewing the SZNZ8F16VMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), low-profile 0402 wettable flank package for AOI compatibility, 50 Ω dynamic impedance at 5 mA, 0.1 µA leakage at 12 V, and automotive-grade qualification per AEC-Q101.
Technical Context
This device operates as a unidirectional voltage reference and clamp, maintaining stable reverse breakdown at 15.2–16.8 V under 5 mA test current. Its low 0.40 mm profile and wettable flank geometry support automated optical inspection and high-density PCB assembly.
Thermal performance is defined by 415 °C/W junction-to-ambient resistance on minimal FR-4 pads, with derating to 1.5 mW/°C above 25 °C. It exhibits a typical temperature coefficient of +9 mV/°C and 65 pF capacitance at 0 V bias and 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.2 V min / 16.8 V max @ IZT = 5 mA - defines clamping threshold range for overvoltage protection |
| Power Dissipation (PD) | 250 mW @ TA = 25 °C - sets maximum continuous power handling on standard FR-4 layout |
| Zener Impedance (ZZT) | 50 Ω max @ IZT = 5 mA - determines regulation stiffness and voltage deviation under load variation |
| Reverse Leakage (IR) | 0.1 µA max @ VR = 12 V - ensures minimal standby current in bias or sensing circuits |
| Capacitance (C) | 65 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and signal integrity in RF-adjacent nodes |
| Forward Voltage (VF) | 0.9 V max @ IF = 10 mA - defines conduction drop when used in forward-biased protection or level-shifting |
| Package | X2DFNW2 (0402) - 1.00 × 0.60 × 0.37 mm footprint with wettable flanks for solder joint inspection |
Pinout & Package
The SZNZ8F16VMX2WT5G is housed in the X2DFNW2 surface-mount package (Case 711BG), measuring 1.00 mm × 0.60 mm × 0.37 mm with wettable flank side walls for AOI compatibility and a low 0.40 mm body height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener cathode terminal | Connected to regulated voltage rail; reverse-biased operation requires this node at higher potential than anode |
| 2 (Anode) | Zener anode terminal | Typically tied to ground or lower-potential reference; completes Zener conduction path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| Wettable Flank Package | Enables reliable automated optical inspection of solder fillets on 0402 footprint without x-ray |
| Pb-Free, Halogen-Free | Complies with RoHS Directive 2011/65/EU and JEDEC JS709E for green manufacturing |
| Low Profile (0.40 mm) | Supports ultra-thin portable designs such as smartphone camera modules and wearable sensors |

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 |
|---|---|---|---|
| NZ8F16VMX2WT5G | No SZ prefix; not AEC-Q101 qualified; same electrical specs and package | Intended for commercial/industrial use only; unsuitable for automotive PPAP programs | Select when automotive qualification is unnecessary and cost sensitivity outweighs qualification requirements |
| SZNZ8F16VSMX2WT5G | Tighter ±2.5% Zener tolerance (15.63–16.37 V); otherwise identical package and ratings | Better suited for precision reference applications requiring tighter voltage stability across temperature and production lot | Choose when system-level accuracy demands sub-3% total voltage error budget and calibration headroom is limited |
Compared with NZ8F16VMX2WT5G, SZNZ8F16VMX2WT5G adds automotive qualification and process controls but retains identical electrical behavior; versus SZNZ8F16VSMX2WT5G, it trades tighter tolerance for broader voltage margin-making it optimal for robust clamping where absolute precision is secondary to ruggedness and supply-chain continuity.

FAQ
What is the Zener voltage tolerance of SZNZ8F16VMX2WT5G?
The SZNZ8F16VMX2WT5G has a Zener voltage tolerance of ±5%, specifying a minimum breakdown voltage of 15.2 V and a maximum of 16.8 V at 5 mA test current (IZT). This tolerance band is confirmed in the Electrical Characteristics table on page 2 of the official datasheet and applies under standard test conditions at TA = 25 °C.
Is SZNZ8F16VMX2WT5G qualified for automotive applications?
Yes, SZNZ8F16VMX2WT5G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the datasheet's Specification Features section and reinforced by the "SZ" prefix denoting automotive and other applications requiring unique site and control change requirements. This qualification covers temperature cycling, mechanical shock, and humidity testing per AEC standards.
What package type does SZNZ8F16VMX2WT5G use, and why is it significant?
SZNZ8F16VMX2WT5G uses the X2DFNW2 (Case 711BG) package-a 0402-sized, wettable flank, 1.00 × 0.60 × 0.37 mm surface-mount outline. Its significance lies in enabling automated optical inspection of solder joints without x-ray, supporting high-yield assembly in space-constrained designs like automotive control units and smartphone camera modules.
What is the maximum power dissipation for SZNZ8F16VMX2WT5G on a standard FR-4 board?
SZNZ8F16VMX2WT5G delivers 250 mW maximum power dissipation on an FR-4 board with minimum pad size and 1 oz. copper (Note 1 in Maximum Ratings table). Above 25 °C, it derates linearly at 1.5 mW/°C-so at 85 °C ambient, usable dissipation drops to approximately 161 mW.
How does the capacitance of SZNZ8F16VMX2WT5G affect its use in high-frequency circuits?
SZNZ8F16VMX2WT5G exhibits 65 pF capacitance at 0 V bias and 1 MHz, measured per the Electrical Characteristics table. This value limits its suitability in RF signal paths above ~100 MHz but remains appropriate for power rail decoupling, ESD protection on low-speed sensor lines, and clamping in digital I/O interfaces where bandwidth below 50 MHz is sufficient.
