Product details
Overview
NZ8F9V1MX2WT5G from onsemi is a 9.1 V ±5% Zener diode in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C with 30 Ω dynamic impedance at 5 mA and 0.5 µA leakage at 6 V, used for precision voltage clamping in space-constrained portable electronics.
For engineers reviewing the NZ8F9V1MX2WT5G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, AOI-optimized packaging details, automotive-grade AEC-Q101 qualification status, and validated alternative options for voltage regulation design.
Technical Context
This device operates as a unidirectional Zener diode with sharp reverse breakdown at nominal 9.1 V, designed for low-profile surface-mount voltage reference and overvoltage protection. Its X2DFNW2 package enables automated optical inspection via wettable flanks and supports high-density PCB layouts.
Thermal performance is defined by 415 °C/W junction-to-ambient resistance on FR-4 with minimum pad layout, and it maintains stable regulation across −65 °C to +150 °C operating range. The 80 pF capacitance at 0 V bias supports ESD-sensitive signal line protection without compromising high-frequency response.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Power Dissipation (PD) | 250 mW at TA = 25 °C - sets maximum continuous power handling on standard FR-4 board |
| Zener Impedance (ZZT) | 30 Ω max at IZT = 5 mA - ensures minimal voltage shift under load variation |
| Leakage Current (IR) | 0.5 µA max at VR = 6 V - guarantees low standby current in battery-powered systems |
| Capacitance (C) | 80 pF max at VR = 0 V, f = 1 MHz - limits signal distortion in high-speed data line protection |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - enables predictable forward conduction behavior during transient events |
| Package | X2DFNW2 (0402, 1.00 × 0.60 × 0.37 mm) - provides wettable flank geometry for AOI-compatible solder joint inspection |

FAQ
What is the Zener voltage tolerance for NZ8F9V1MX2WT5G?
The NZ8F9V1MX2WT5G has a Zener voltage range of 8.65 V to 9.56 V at test current IZT = 5 mA, corresponding to ±5% tolerance around the nominal 9.1 V rating. This tolerance is confirmed in the Electrical Characteristics table on page 2 of the official onsemi datasheet revision 4 (November 2025). The NZ8F9V1MX2WT5G meets this specification under standard test conditions and is intended for applications requiring moderate voltage regulation precision.
Is NZ8F9V1MX2WT5G qualified for automotive use?
Yes, NZ8F9V1MX2WT5G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the datasheet's Specification Features section. It carries the SZ prefix option (e.g., SZNZ8F9V1MX2WT5G) for automotive applications requiring unique site and process controls. The NZ8F9V1MX2WT5G operates reliably across −65 °C to +150 °C and is designed for use in automotive control units such as body electronics and infotainment power domains.
What is the maximum power dissipation of NZ8F9V1MX2WT5G on a standard FR-4 board?
The maximum power dissipation for NZ8F9V1MX2WT5G is 250 mW at ambient temperature TA = 25 °C on an FR-4 board with minimum pad layout (1 oz. Cu), per Note 1 in the Maximum Ratings table. Derating is required at 1.5 mW/°C above 25 °C. This value is measured under standardized thermal conditions and applies directly to the NZ8F9V1MX2WT5G in its X2DFNW2 package configuration.
Does NZ8F9V1MX2WT5G support automated optical inspection (AOI)?
Yes, NZ8F9V1MX2WT5G features a wettable flank X2DFNW2 package specifically designed for optimal AOI. The side-wall metallization allows full solder joint inspection without X-ray, improving manufacturing yield and reliability verification. This feature is highlighted in the datasheet's Specification Features section and is intrinsic to the NZ8F9V1MX2WT5G package construction, not dependent on board layout or process settings.
What is the reverse leakage current specification for NZ8F9V1MX2WT5G?
The reverse leakage current for NZ8F9V1MX2WT5G is specified as 0.5 µA maximum at VR = 6 V, per the Electrical Characteristics table on page 2 of the onsemi datasheet. This parameter is measured at TA = 25 °C and defines the off-state current draw critical for battery-powered applications. The NZ8F9V1MX2WT5G maintains this low leakage across its full operating temperature range, supporting energy-efficient system design.
