Product details
Overview
NZ8DH9V1MXWT5G 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 9.30 V, clamping voltage of 10.90 V at 1.0 A, leakage current ≤0.5 µA at VRWM, capacitance of 25 pF at 0 V, and IEC 61000-4-2 ±30 kV contact/air ESD rating - deployed in automotive ECUs and IVN interfaces.
For engineers reviewing the NZ8DH9V1MXWT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under 1.0 A pulse, ultra-low 25 pF capacitance for high-speed data lines, wettable flank XDFNW2 package for AOI compatibility, and AEC-Q101 qualification for automotive deployment.
Technical Context
This device implements a symmetric bidirectional Zener clamp between two terminals, enabling protection of single-ended I/O lines against both positive and negative transients without polarity constraints. Its breakdown voltage (9.30–10.70 V) and clamping voltage (10.90 V @ 1.0 A) are specified per IEC 61000-4-2 and ISO 10605 test waveforms.
Thermal design leverages a 175 °C maximum junction temperature and 400 °C/W junction-to-ambient thermal resistance (on FR-4 with minimum pad), supporting operation in under-hood automotive environments. The XDFNW2 package provides wettable flanks for automated optical inspection and replaces legacy SOT-23 dual-diode configurations with reduced footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM Max | 9.30 V - Maximum continuous reverse operating voltage before significant leakage |
| VBR Min/Max | 9.30 V / 10.70 V - Breakdown occurs within this range at 5 mA test current |

Applications
| Automotive Engine Control Unit (ECU) | In-Vehicle Networking (IVN) |
|---|---|
Use Scenario: Protecting sensor input lines (e.g., crankshaft position, MAP) from load dump and alternator ripple transients in 12 V systems. IC Role / Device Role: Bidirectional transient voltage suppressor placed between sensor interface IC and connector. Use Value: Clamps surges to ≤10.90 V while adding only 25 pF capacitance, preserving analog signal fidelity and ADC accuracy. | Use Scenario: ESD protection on CAN FD physical layer traces running between domain controllers and ADAS sensors. IC Role / Device Role: Line-side TVS diode on differential CANH/CANL pairs, mounted adjacent to connector. Use Value: ±30 kV ESD immunity and low 25 pF capacitance prevent bit errors and maintain >5 Mbps data integrity. |
| Infotainment Display Interface | Body Control Module (BCM) LIN Bus |
Use Scenario: Guarding MIPI D-PHY or eDP lanes between SoC and display panel against board-level ESD during assembly and service. IC Role / Device Role: Per-lane unidirectional/bidirectional clamp (configured as bidirectional here) on high-speed video data lines. Use Value: 25 pF capacitance avoids eye diagram degradation; 10.90 V clamping prevents receiver input damage during hot-plug events. | Use Scenario: Protecting LIN transceiver pins from battery disconnect spikes and electrostatic discharge in door module wiring harnesses. IC Role / Device Role: Single-channel bidirectional TVS on LIN bus line between transceiver and vehicle harness connector. Use Value: 9.30 V VRWM aligns with LIN's 12 V supply; 10.90 V VC limits stress on transceiver's 16 V absolute max rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SZ1.5SMC9.0A | Unidirectional, 9.0 V VRWM, 1500 W peak power, DO-214AB package (3.5 mm × 3.5 mm) | Larger footprint; suited for higher-energy surges but incompatible with space-constrained automotive PCBs | Select when surge energy exceeds 4.5 A (8/20 µs) and board area permits larger package |
| TPD2E001DRYR | Bi-directional, 5.5 V VRWM, 12 pF capacitance, X2SON-2 package (0.8 mm × 0.8 mm) | Lower clamping voltage and capacitance; insufficient for 12 V automotive supply rail coupling | Select for low-voltage, high-speed interfaces (e.g., USB Type-C CC lines) where VRWM < 6 V is acceptable |
Compared with SZ1.5SMC9.0A and TPD2E001DRYR, NZ8DH9V1MXWT5G uniquely balances 9.30 V VRWM, 10.90 V clamping, 25 pF capacitance, and XDFNW2 footprint - making it optimal for compact, high-reliability 12 V automotive signal protection where both voltage margin and layout density matter.

FAQ
What is the maximum working peak reverse voltage of NZ8DH9V1MXWT5G?
The maximum working peak reverse voltage (VRWM) of NZ8DH9V1MXWT5G is 9.30 V. This value defines the highest continuous DC or repetitive peak reverse voltage the device can withstand without entering breakdown. It ensures compatibility with 12 V automotive systems where transient-free operating margins must be maintained below the clamping threshold of 10.90 V.
Does NZ8DH9V1MXWT5G meet automotive qualification standards?
Yes, NZ8DH9V1MXWT5G is AEC-Q101 qualified and PPAP capable. The "SZ" prefix variant (e.g., SZNZ8DH9V1MXWT5G) explicitly denotes automotive-grade manufacturing controls, but the base NZ8DH9V1MXWT5G shares identical electrical and thermal specifications and is rated for −55 °C to +175 °C junction temperature - fulfilling mission-critical automotive environmental requirements.
What is the clamping voltage of NZ8DH9V1MXWT5G and how is it measured?
The clamping voltage (VC) of NZ8DH9V1MXWT5G is 10.90 V, measured at a peak pulse current (IPP) of 1.0 A with an 8/20 µs waveform per IEC 61000-4-2. This value represents the maximum voltage seen across the protected line during a standardized surge event - directly determining stress on downstream ICs and validating design margin against their absolute maximum ratings.
How does the 25 pF capacitance of NZ8DH9V1MXWT5G impact high-speed data lines?
The 25 pF typical capacitance of NZ8DH9V1MXWT5G at 0 V bias and 1 MHz minimizes signal rise-time degradation and reflection on automotive serial buses. For example, on a 5 Mbps CAN FD line, this capacitance introduces <0.5% timing skew and preserves eye opening - unlike higher-capacitance alternatives that risk bit errors or require complex equalization.
Is NZ8DH9V1MXWT5G supplied in a wettable flank package and why does it matter?
Yes, NZ8DH9V1MXWT5G uses the XDFNW2 package with wettable flanks. This feature enables automated optical inspection (AOI) of solder joints on bottom-terminated components - a mandatory requirement for automotive PCB assembly traceability and zero-defect quality programs. It eliminates reliance on X-ray inspection for process validation.
