Product details
Overview
NZ8DH47VMXWT5G from onsemi is a bidirectional Zener protection diode designed for ESD and transient overvoltage suppression in voltage-sensitive signal lines. It features a working peak reverse voltage of 44.55 V (min), clamping voltage of 52.70 V at 1.0 A, ±30 kV IEC 61000-4-2 contact ESD rating, and 8 pF typical capacitance at 0 V - ideal for high-speed automotive IVN interfaces.
For engineers reviewing the NZ8DH47VMXWT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under 1.0 A pulse, low 8 pF capacitance for minimal signal distortion, AEC-Q101 qualification, wettable flank XDFNW2 package for AOI, and 175 °C max junction temperature for under-hood deployment.
Technical Context
This device implements a single-channel, bidirectional Zener clamp topology optimized for fast transient response to ESD events per IEC 61000-4-2 and ISO 10605 standards. Its symmetrical breakdown behavior (VBR = 44.55–51.25 V) enables robust protection of differential or single-ended lines without polarity constraints.
The XDFNW2 1.0 × 0.6 mm package integrates wettable flanks for automated optical inspection and supports high-density PCB layouts. Thermal design is enabled by RJA = 400 °C/W and TJ(MAX) = +175 °C, allowing operation in harsh automotive environments where sustained ambient temperatures exceed 125 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SZ1.5SM47AHE3/A/H | DO-214AC package (4.5 × 3.5 mm); higher 52.2 V VBR min; 100 W peak power vs. 300 mW | Higher power handling but 3× larger footprint; unsuitable for space-constrained IVN nodes | Select only when surge energy exceeds 4.5 A 8/20 µs and board area permits larger package |
| TPD2E001DRYR | 2-channel, 12 pF per line, 5 V VRWM; DSBGA package; lower voltage rating and higher capacitance | Targeted at USB/IO protection, not automotive high-voltage signal lines | Not suitable for 44.55 V VRWM requirement; use only for sub-6 V digital I/O protection |
Compared with SZ1.5SM47AHE3/A/H and TPD2E001DRYR, NZ8DH47VMXWT5G uniquely delivers AEC-Q101 qualification, 8 pF capacitance, and XDFNW2 footprint in a 44.55 V-rated device - enabling compact, high-reliability ESD protection for next-generation automotive serial buses.

FAQ
What is the maximum working peak reverse voltage (VRWM) of NZ8DH47VMXWT5G?
The maximum working peak reverse voltage (VRWM) of NZ8DH47VMXWT5G is 44.55 V, defined as the highest DC or continuous reverse voltage that can be applied without exceeding 0.1 µA leakage current. This value ensures safe operation on 36 V automotive systems with margin, and is verified per the onsemi datasheet Electrical Characteristics table under TA = 25 °C conditions.
Does NZ8DH47VMXWT5G meet AEC-Q101 qualification requirements?
Yes, NZ8DH47VMXWT5G is AEC-Q101 qualified and PPAP capable, as confirmed in the onsemi datasheet Features section and Ordering Information footnote. The "SZ" prefix variant is explicitly designated for automotive applications, and the standard NZ8DH47VMXWT5G shares the same qualification status and process controls per onsemi's published compliance documentation.
What is the clamping voltage of NZ8DH47VMXWT5G at 1.0 A peak pulse current?
The clamping voltage (VC) of NZ8DH47VMXWT5G is 52.70 V at 1.0 A peak pulse current (8/20 µs waveform), as specified in the Electrical Characteristics table. This value represents the maximum voltage seen across the device during standardized surge testing and defines the upper limit of protection for downstream circuitry.
Is NZ8DH47VMXWT5G suitable for high-speed data lines such as CAN FD?
Yes, NZ8DH47VMXWT5G is suitable for CAN FD due to its 8 pF typical capacitance at 0 V bias and 52.70 V clamping voltage - both aligned with CAN FD physical layer requirements. Its bidirectional symmetry and low leakage (<0.1 µA) prevent signal distortion or DC loading, and the XDFNW2 package enables placement directly at the connector for optimal transient suppression.
What package type does NZ8DH47VMXWT5G use, and why is it advantageous?
NZ8DH47VMXWT5G uses the XDFNW2 (Case 521AE) package: a 1.0 × 0.6 mm, 2-terminal, wettable flank leadless package. This design enables automated optical inspection (AOI), reduces PCB area versus SOT-23 alternatives, and supports high-density routing in automotive ECUs - all while maintaining thermal capability up to 175 °C junction temperature.
