Product details
Overview
NZ8F16VSMX2WT5G from onsemi is a 16 V ±2.3% tight-tolerance Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C with 50 Ω dynamic impedance at 5 mA test current and 0.1 µA leakage at 12 V reverse bias - used for precision voltage clamping in automotive control units and portable power rails.
For engineers reviewing the NZ8F16VSMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q101 qualification status, 0.40 mm body height for AOI compatibility, ±0.37 V Zener voltage tolerance at 25 °C, and thermal resistance of 415 °C/W on FR-4 with minimum pad layout.
Technical Context
This device operates as a unidirectional voltage reference diode with sharp reverse breakdown at nominal 16 V, specified under IZT = 5 mA. Its low-profile X2DFNW2 package enables high-density PCB layouts while supporting automated optical inspection via wettable flanks.
The NZ8F16VSMX2WT5G exhibits a temperature coefficient of +9 mV/°C (typical), stable capacitance of 65 pF at 0 V and 1 MHz, and forward voltage ≤0.9 V at 10 mA - enabling reliable DC rail protection without signal coupling interference in low-voltage mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.63 V to 16.37 V at IZT = 5 mA - defines precise clamping threshold for 16 V nominal supply rails |
| Power Dissipation (PD) | 250 mW on FR-4 with 1 oz. Cu minimum pad - sets maximum continuous clamp energy before thermal derating |
| Zener Impedance (ZZT) | 50 Ω max at IZT = 5 mA - ensures minimal voltage shift under dynamic load transients |
| Reverse Leakage (IR) | 0.1 µA max at VR = 12 V - guarantees negligible standby current in always-on circuits |
| Capacitance (C) | 65 pF at VR = 0 V, f = 1 MHz - limits high-frequency noise coupling into protected nodes |
| Package | X2DFNW2 (0402, 1.00 × 0.60 × 0.37 mm) - supports 0.65 mm pitch AOI-compatible assembly |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
X2DFNW2 surface-mount package with 2-terminal configuration: ultra-low profile (0.40 mm height), wettable flank side walls for solder joint inspection, and industry-standard 0402 footprint (1.00 mm × 0.60 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown anode connection point | Connected to regulated voltage node; polarity must be observed to enable reverse-bias conduction |
| 2 (Anode) | Zener breakdown cathode connection point | Typically tied to ground or lower-potential reference; completes clamp path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Tight Zener tolerance | ±2.3% (15.63–16.37 V) enables accurate 16 V rail clamping without post-production calibration |
| Wettable flank leads | Side-wall metallization supports automated optical inspection of solder fillet integrity on fine-pitch boards |
| AEC-Q101 qualification | Validated for automotive under-hood and infotainment applications per stress test requirements |
| Pb-free, Halogen-free | RoHS-compliant construction meets EU Directive 2011/65/EU and JEDEC JS709E material standards |
| Low thermal resistance | 415 °C/W junction-to-ambient (FR-4 min pad) allows sustained operation up to +125 °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 |
|---|---|---|---|
| BZX84-C16LT1G | Standard 5% tolerance (15.2–16.8 V), 300 mW rating, SOT-23 package (1.3 × 0.9 mm) | Larger footprint, higher leakage (1 µA @ 12 V), no AEC-Q101 qualification | Select when cost sensitivity outweighs space constraints and automotive compliance is not required |
| MMSZ5245B-TP | 5% tolerance (15.2–16.8 V), 500 mW rating, SOD-123 package (2.7 × 1.4 mm) | Double the power rating but 6× larger area; lacks wettable flanks and AEC-Q101 validation | Prefer for industrial power supplies needing higher surge margin where board space permits |
Compared with NZ8F16VSMX2WT5G, BZX84-C16LT1G offers lower unit cost but sacrifices automotive qualification and AOI capability, while MMSZ5245B-TP trades miniaturization for higher power handling - making NZ8F16VSMX2WT5G optimal for space-constrained AEC-Q101 designs requiring production traceability and optical inspection support.

FAQ
What is the Zener voltage tolerance of NZ8F16VSMX2WT5G?
The NZ8F16VSMX2WT5G has a tight Zener voltage tolerance of ±2.3%, specified as 15.63 V to 16.37 V at IZT = 5 mA and TA = 25 °C. This tighter tolerance than standard Zener series improves accuracy in voltage reference and clamping applications where regulation stability is critical, such as in automotive sensor biasing and USB-C PD supervision circuits using the NZ8F16VSMX2WT5G.
Is NZ8F16VSMX2WT5G qualified for automotive use?
Yes, NZ8F16VSMX2WT5G is AEC-Q101 qualified and PPAP capable, with validation across temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge tests per automotive reliability standards. The "SZ" prefix variant (SZNZ8F16VSMX2WT5G) is explicitly designated for automotive applications requiring unique site and control change tracking - confirming that NZ8F16VSMX2WT5G meets the same qualification baseline.
What is the maximum power dissipation of NZ8F16VSMX2WT5G?
NZ8F16VSMX2WT5G is rated for 250 mW total device dissipation on FR-4 board with minimum pad layout (1 oz. Cu) at 25 °C, derating linearly at 1.5 mW/°C above that temperature. This rating reflects its optimized thermal path in the X2DFNW2 package and defines safe continuous operation limits - essential for designing robust overvoltage protection in compact consumer and automotive electronics using NZ8F16VSMX2WT5G.
Does NZ8F16VSMX2WT5G support automated optical inspection (AOI)?
Yes, NZ8F16VSMX2WT5G uses the X2DFNW2 package with wettable flank side walls, enabling reliable solder joint inspection via automated optical inspection systems. This feature is explicitly highlighted in the datasheet as a key benefit for high-yield SMT assembly - particularly valuable in automotive and medical manufacturing lines where solder defect detection is mandatory, and directly supported by the physical construction of NZ8F16VSMX2WT5G.
What is the reverse leakage current specification for NZ8F16VSMX2WT5G?
NZ8F16VSMX2WT5G specifies a maximum reverse leakage current (IR) of 0.1 µA at VR = 12 V and TA = 25 °C. This ultra-low leakage supports energy-sensitive applications like battery-backed medical monitors and always-on automotive modules, where minimizing standby current is critical - a verified parameter confirmed in the Electrical Characteristics table for NZ8F16VSMX2WT5G on page 3 of the official onsemi datasheet.
