Product details
Overview
NZ8F27VMX2WT5G from onsemi is a 27 V Zener diode voltage regulator in X2DFNW2 (0402) wettable flank package, rated for 250 mW dissipation at 25 °C on FR-4 board with 1 oz. Cu, featuring 25.65–28.35 V nominal Zener voltage at 5 mA test current, 80 Ω maximum dynamic impedance, and 0.1 µA reverse leakage at 22 V. It delivers precision voltage clamping in space-constrained power rail protection circuits.
For engineers reviewing the NZ8F27VMX2WT5G datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, thermal derating behavior, AOI-compatible packaging details, and AEC-Q101-comparable alternatives for automotive and portable electronics design.
Technical Context
The NZ8F27VMX2WT5G operates as a unidirectional Zener diode with sharp reverse breakdown at 27 V nominal, optimized for low-profile voltage regulation and transient suppression. 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 minimum-pad FR-4, with linear derating of 1.5 mW/°C above 25 °C. The device exhibits a typical temperature coefficient near +9 mV/°C across −55 to +150 °C, and capacitance of 50 pF at 0 V bias and 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25.65–28.35 V @ IZT = 5 mA - defines clamping threshold for overvoltage protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C27LT1G | 27 V nominal, ±5% tolerance, SOT-23 package (1.3 × 1.3 × 0.9 mm), 350 mW PD | Larger footprint; higher power but less suitable for ultra-dense layouts | Select when higher power margin or legacy SOT-23 reflow compatibility is required |
| MMBZ5256BLT1G | 27 V nominal, ±5% tolerance, SOT-23 package, 225 mW PD, 100 Ω ZZT | Higher dynamic impedance and same package size; no wettable flanks | Choose for cost-sensitive non-AOI production where 100 Ω ZZT is acceptable |
Compared with NZ8F27VMX2WT5G, BZX84-C27LT1G offers greater power headroom but occupies 3× more board area, while MMBZ5256BLT1G trades AOI support and tighter impedance for lower unit cost in standard SOT-23 assembly lines.

FAQ
What is the Zener voltage tolerance of NZ8F27VMX2WT5G?
The NZ8F27VMX2WT5G has a Zener voltage range of 25.65 V to 28.35 V at 5 mA test current, corresponding to ±5% tolerance about the nominal 27 V rating. This tolerance is specified per the standard tolerance series (MX2W) and confirmed in the Electrical Characteristics table on page 2 of the onsemi datasheet. The device does not include tighter-tolerance variants unless ordered as NZ8F27VSMX2WT5G.
Is NZ8F27VMX2WT5G qualified for automotive applications?
NZ8F27VMX2WT5G itself is not AEC-Q101 qualified, but its SZ-prefix variant - SZNZ8F27VMX2WT5G - is fully AEC-Q101 qualified and PPAP capable. The base part shares identical electrical and mechanical specifications, differing only in traceability and process controls required for automotive production. Engineers targeting automotive use must specify the SZ prefix to ensure qualification compliance.
What is the thermal resistance of NZ8F27VMX2WT5G on a standard PCB?
The NZ8F27VMX2WT5G has a junction-to-ambient thermal resistance (RJA) of 415 °C/W when mounted on an FR-4 board with minimum pad size and 1 oz. copper. This value assumes the layout defined in Note 1 of the Maximum Ratings table. Derating is linear at 1.5 mW/°C above 25 °C ambient, meaning usable power drops to ~175 mW at 75 °C ambient.
Does NZ8F27VMX2WT5G support automated optical inspection (AOI)?
Yes, NZ8F27VMX2WT5G uses the X2DFNW2 package with wettable flanks, enabling full coverage AOI of solder fillets without requiring X-ray inspection. This feature is explicitly called out in the Specification Features section of the datasheet and is critical for high-yield manufacturing of compact consumer and automotive PCBs where visual access to solder joints is limited.
What is the maximum reverse leakage current for NZ8F27VMX2WT5G?
The maximum reverse leakage current for NZ8F27VMX2WT5G is 0.1 µA at VR = 22 V and TA = 25 °C, as specified in the Electrical Characteristics table. This low leakage supports long battery life in always-on monitoring circuits and ensures minimal loading on high-impedance voltage divider networks used in precision sensing applications involving NZ8F27VMX2WT5G.
