Product details
Overview
NZ9F11VT5G from onsemi is a 250 mW, 11 V Zener voltage regulator diode in SOD-923 package, designed for precision voltage clamping and overvoltage protection in space-constrained portable electronics. Its nominal Zener voltage is 11.0 V (min 10.45 V, max 11.55 V at IZT = 5 mA), with 30 Ω max Zener impedance at test current and 0.1 µA max reverse leakage at 8.0 V.
For engineers reviewing the NZ9F11VT5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 11 V regulation tolerance, 250 mW power rating on FR-5 board, SOD-923 footprint compatibility, Class 3 ESD robustness (>16 kV HBM), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a two-terminal, silicon planar Zener diode optimized for stable reverse-bias voltage regulation. It delivers precise clamping with ±5% nominal voltage tolerance, low dynamic impedance (30 Ω max at 5 mA), and minimal temperature coefficient (+5.4 mV/°C) - enabling predictable performance across −65 °C to +150 °C junction temperature range.
The SOD-923 package supports high-density PCB layouts with 1.00 mm × 0.60 mm body and 0.40 mm height. Its 100% matte tin lead finish, MSL 1 rating, and 260 °C reflow compatibility ensure manufacturability in automated SMT processes without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.45–11.55 V @ IZT = 5 mA - defines clamping threshold with ±5% tolerance for stable reference or protection |
| Power Dissipation (PD) | 250 mW @ TA = 25 °C - sets maximum continuous DC power handling on standard FR-5 board |
| Zener Impedance (ZZT) | ≤30 Ω @ IZT = 5 mA - ensures low AC impedance for effective noise suppression and fast transient response |
| Reverse Leakage (IR) | ≤0.1 µA @ VR = 8.0 V - guarantees minimal standby current in undervoltage or off-state conditions |
| ESD Rating (HBM) | Class 3 (>16 kV) - provides robust electrostatic discharge immunity for handheld and exposed interface circuits |
| Operating Temperature | −65 °C to +150 °C - supports deployment in automotive under-hood, industrial, and consumer environments |
| Package | SOD-923 (Case 514AB) - 1.00 mm × 0.60 mm × 0.37 mm footprint ideal for ultra-compact PCBs |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C11LT1G | Same 11 V nominal Zener voltage, but 300 mW PD, SOD-523 package (0.8 × 0.6 mm), higher ZZT (40 Ω) | Higher power margin but slightly larger footprint; less suitable for ultra-thin wearables | Select when higher surge energy absorption is required and board space allows SOD-523 |
| MMSZ5240BT1G | 10 V nominal Zener, 500 mW PD, SOD-123 package (3.7 × 1.6 mm), ZZT = 17 Ω @ 20 mA | Lower voltage rating and significantly larger footprint; better for general-purpose boards with layout flexibility | Select when 10 V regulation suffices and thermal dissipation >250 mW is needed |
Compared with BZX584C11LT1G and MMSZ5240BT1G, NZ9F11VT5G offers the smallest footprint (SOD-923), tightest voltage tolerance (±5%), and automotive qualification - making it optimal for space- and reliability-critical designs where 11 V clamping is mandatory.

FAQ
What is the Zener voltage tolerance of NZ9F11VT5G?
The NZ9F11VT5G has a specified Zener voltage range of 10.45 V to 11.55 V at test current IZT = 5 mA, corresponding to a ±5% tolerance around the nominal 11.0 V rating. This tolerance is guaranteed across the full operating temperature range and is measured under pulse test conditions at 25 °C ambient, as documented in the official onsemi datasheet revision 5.
Is NZ9F11VT5G suitable for automotive applications?
Yes, NZ9F11VT5G is AEC-Q101 qualified and PPAP capable, with the "SZ" prefix variant (SZNZ9F11VT5G) explicitly designated for automotive use. The device meets stringent reliability, thermal, and ESD requirements - including Class 3 HBM (>16 kV) and operation from −65 °C to +150 °C - making it appropriate for engine control units, ADAS cameras, and infotainment power rails.
What is the maximum power dissipation for NZ9F11VT5G on a standard PCB?
NZ9F11VT5G is rated for 250 mW total device dissipation on an FR-5 board at 25 °C ambient temperature. Power derating is linear at 2.0 mW/°C above 25 °C, reaching zero dissipation at 150 °C ambient. This rating assumes minimum pad design per JEDEC standards and is validated per onsemi's published thermal resistance (RJA = 500 °C/W).
Does NZ9F11VT5G have a defined polarity marking, and how is it identified?
Yes, NZ9F11VT5G uses Style 1 marking per the SOD-923 mechanical drawing: Pin 1 (cathode) is identified by a visible polarity band at one end of the package. The anode (Pin 2) is the unmarked end. This marking aligns with industry-standard SOD-923 orientation and must be matched to PCB silkscreen for correct reverse-bias operation during Zener regulation.
What packaging and reel specifications apply to NZ9F11VT5G?
NZ9F11VT5G is supplied in Pb-free tape-and-reel packaging with 8,000 units per reel. The device uses standard SOD-923 carrier tape per onsemi's BRD8011/D specification, with correct part orientation (cathode-first) and EIA-481-compliant sprocket holes. Reel dimensions and cover tape peel strength comply with IPC-7351 and J-STD-033 requirements for automated placement.
