Product details
Overview
NZ9F13VST5G from onsemi is a 13.2 V ±4.5% Zener diode in SOD-923 package, rated for 250 mW steady-state power dissipation at 25°C with 37 Ω max Zener impedance at 5 mA test current and 10 μA max reverse leakage at 10.4 V. It provides precision voltage regulation in space-constrained portable electronics such as smartphones and high-density PCBs.
For engineers reviewing the NZ9F13VST5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 13.2 V nominal Zener voltage, ±4.5% tolerance, 37 Ω dynamic impedance, AEC-Q101 qualification, and SOD-923 footprint compatibility with tight board area constraints.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in silicon PN junction. Its thermal resistance of 500°C/W and derating slope of 2.0 mW/°C above 25°C define safe operating limits under varying ambient conditions. The 16 kV HBM ESD rating enables robust handling in automated assembly lines.
Designed for low-capacitance operation (75 pF max at 0 V, 1 MHz), it supports fast transient response in signal conditioning and overvoltage clamping. The −65°C to +150°C junction temperature range and Pb-free matte tin lead finish ensure reliability across automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.91 V min / 13.49 V max at IZT = 5 mA - defines regulated output voltage window under nominal bias |
| Zener Impedance (ZZT) | 37 Ω max at IZT = 5 mA - determines AC voltage variation under load transients |
| Power Dissipation (PD) | 250 mW at TA = 25°C - sets maximum continuous DC power before thermal derating applies |
| Reverse Leakage (IR) | 0.1 μA max at VR = 10.4 V - ensures minimal standby current in voltage-sense circuits |
| Capacitance (C) | 75 pF max at VR = 0 V, f = 1 MHz - limits high-frequency signal distortion in RF-coupled protection paths |
| ESD Rating | Class 3 (>16 kV) per HBM - guarantees survivability during manual handling and pick-and-place operations |
| Operating Temperature | −65°C to +150°C - supports deployment in under-hood automotive and industrial control modules |

FAQ
What is the exact Zener voltage range specified for NZ9F13VST5G?
The NZ9F13VST5G has a guaranteed Zener voltage range of 12.91 V minimum to 13.49 V maximum at a test current of 5 mA, corresponding to a ±4.5% tolerance around the nominal 13.2 V rating. This specification is measured under standard conditions (TA = 25°C) and is documented in the Electrical Characteristics table on page 3 of the official onsemi datasheet. The NZ9F13VST5G maintains this voltage window across its full operating temperature range when used within its power and current limits.
Is NZ9F13VST5G qualified for automotive applications?
Yes, NZ9F13VST5G is AEC-Q101 qualified and PPAP capable, as confirmed by the "SZ" prefix variant designation in the datasheet's ordering information and electrical characteristics table. The device meets stress testing requirements for temperature cycling, humidity bias, and mechanical shock applicable to automotive electronic control units. NZ9F13VST5G is explicitly recommended for body electronics, infotainment power rails, and sensor reference circuits where automotive-grade reliability is mandated.
What is the maximum power dissipation of NZ9F13VST5G and how does it change with temperature?
NZ9F13VST5G has a maximum steady-state power dissipation of 250 mW at ambient temperature (TA) = 25°C. Above 25°C, it derates linearly at 2.0 mW/°C, reaching zero dissipation at 150°C. This derating behavior is defined by its thermal resistance of 500°C/W and is validated on FR-4 PCB with minimum pad layout. Engineers must apply this derating curve when calculating safe operating area in thermally constrained enclosures where NZ9F13VST5G is deployed.
Does NZ9F13VST5G have a specified capacitance value, and why does it matter?
Yes, NZ9F13VST5G has a maximum capacitance of 75 pF measured at VR = 0 V and frequency = 1 MHz. This parameter is critical in high-speed signal path protection-such as USB data lines or RF front-end bias networks-where excessive diode capacitance can attenuate signals or cause timing skew. The low 75 pF value of NZ9F13VST5G enables effective clamping without degrading signal integrity in bandwidth-sensitive applications.
What marking code identifies NZ9F13VST5G on the physical device?
NZ9F13VST5G is marked with "2" on the top surface of the SOD-923 package, as shown in the Device Marking Information section (page 3) of the onsemi datasheet. This single-character code "2" distinguishes it within the NZ9FxxxST5G family and corresponds to the 13 V Zener voltage bin. The marking is laser-etched on the cathode-side surface, with pin 1 (cathode) identified by the mark location per the standard SOD-923 orientation diagram. No date or lot codes are included in the primary device marking for NZ9F13VST5G.
