Product details
Overview
NZ8F13VSMX2WT5G from onsemi is a 13 V ±2.3% (12.70–13.30 V) Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C with 37 Ω dynamic impedance at 5 mA test current and 0.1 µA leakage at 10 V reverse bias - used for precision voltage clamping in space-constrained automotive control units and portable electronics.
For engineers reviewing the NZ8F13VSMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include tight 5% Zener tolerance, AEC-Q101 qualification, wettable flank geometry for AOI compatibility, and low 0.40 mm body height in 0402 footprint.
Technical Context
This device operates as a unidirectional voltage reference diode, conducting in reverse breakdown to clamp transient overvoltages or stabilize bias points. Its 13 V nominal Zener voltage is specified at 5 mA test current (IZT), with temperature coefficient of ±6 mV/°C across −55 °C to +150 °C junction range.
The X2DFNW2 package features solderable side walls enabling automated optical inspection, and thermal resistance of 415 °C/W (FR-4, minimum pad) supports reliable operation under pulsed power conditions up to 40 W non-repetitive peak reverse power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.70–13.30 V @ IZT = 5 mA - defines precise clamping threshold for 12 V rail protection |
| Power Dissipation (PD) | 250 mW @ TA = 25 °C - limits continuous steady-state energy handling on standard FR-4 PCB |
| Zener Impedance (ZZT) | 37 Ω @ IZT = 5 mA - determines regulation stiffness and voltage deviation under load variation |
| Leakage Current (IR) | 0.1 µA @ VR = 10 V - ensures minimal standby current draw in battery-powered systems |
| Capacitance (C) | 75 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and signal integrity in RF-adjacent circuits |
| Package | X2DFNW2 (0402, 1.00 × 0.60 × 0.37 mm) - enables ultra-dense placement and AOI-compatible solder joint inspection |
| AEC-Q101 Qualified | Yes - validates reliability for automotive electronic control modules per stress test requirements |
Pinout & Package

FAQ
What is the Zener voltage tolerance of NZ8F13VSMX2WT5G?
NZ8F13VSMX2WT5G has a tight 5% Zener voltage tolerance, specified as 12.70 V to 13.30 V at 5 mA test current (IZT). This tolerance band ensures consistent clamping behavior across temperature and production lots, making NZ8F13VSMX2WT5G suitable for applications demanding precise voltage reference stability such as automotive sensor biasing and USB-C VCONN regulation.
Is NZ8F13VSMX2WT5G qualified for automotive use?
Yes, NZ8F13VSMX2WT5G is AEC-Q101 qualified and PPAP capable. It meets the stress test requirements for automotive electronic components including temperature cycling, humidity testing, and mechanical shock - confirming its suitability for deployment in engine control units, body control modules, and ADAS sensor subsystems where reliability under harsh operating conditions is mandatory.
What package type does NZ8F13VSMX2WT5G use, and why is it significant?
NZ8F13VSMX2WT5G uses the X2DFNW2 package - a 0402-sized (1.00 × 0.60 × 0.37 mm), wettable flank, leadless DFN variant. Its significance lies in enabling automated optical inspection of solder joints without x-ray, supporting zero-defect manufacturing in high-volume automotive PCB assembly while maintaining ultra-low profile for space-constrained designs.
What is the maximum power dissipation of NZ8F13VSMX2WT5G at room temperature?
NZ8F13VSMX2WT5G has a maximum power dissipation of 250 mW at ambient temperature (TA) of 25 °C on FR-4 board with minimum pad layout. Derating is required above 25 °C at 1.5 mW/°C, meaning usable power drops to 225 mW at 40 °C ambient - a key constraint when designing for sustained clamping in thermally dense automotive modules.
How does the leakage current of NZ8F13VSMX2WT5G compare to standard Zeners at 10 V reverse bias?
At 10 V reverse bias, NZ8F13VSMX2WT5G exhibits only 0.1 µA leakage current - significantly lower than typical 13 V Zeners that often specify 1–5 µA in same condition. This ultra-low leakage directly extends battery life in always-on wearable and IoT sensor applications, where NZ8F13VSMX2WT5G contributes measurable runtime gains over legacy alternatives.
