Product details
Overview
NZ8P24VMX2WT5G from onsemi is a unidirectional Zener protection diode designed for ESD and transient overvoltage suppression in voltage-sensitive circuits. It features a 24 V working peak reverse voltage (VRWM), 35 V clamping voltage at 1.0 A (8/20 µs), 22 pF junction capacitance, and ±30 kV IEC 61000-4-2 ESD rating - deployed in automotive ECUs and in-vehicle networking interfaces.
For engineers reviewing the NZ8P24VMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under 1.0 A/4.5 A pulses, wettable flank X2DFNW2 package compatibility with AOI, and AEC-Q101 qualification for automotive use.
Technical Context
This device operates as a single-channel, unidirectional TVS diode optimized for fast transient suppression. Its breakdown voltage is specified at 26.3–27.7 V (min/max) at 5 mA test current, with clamping voltages of 35 V (IPP = 1.0 A), 56 V (IPP = 4.5 A), and 44 V (IPP = 0.87 A, 10/1000 µs).
The X2DFNW2 package enables high-density PCB layout and automated optical inspection via wettable flanks. It supports operation across −55 °C to +150 °C junction temperature and complies with AEC-Q101 for automotive electronics, including IVN and ECU applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 26.3 V / 27.7 V at IT = 5 mA - defines precise breakdown threshold for reliable triggering |
| VC @ IPP = 1.0 A | 35 V (8/20 µs) - limits transient voltage seen by protected IC during typical ESD events |
| IPP (max) | 4.5 A (8/20 µs) - peak pulse current handling capacity without failure |
| CJ | 22 pF at VR = 0 V, 1 MHz - low capacitance preserves signal integrity in high-speed data lines |
| ESD Rating | ±30 kV contact & air per IEC 61000-4-2 - exceeds industrial and automotive ESD immunity requirements |
Pinout & Package
Package: X2DFNW2 (1.0 mm × 0.6 mm, 0.65 mm pitch), ultra-compact wettable flank leadless package per Case 711BG.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SZ1.5SM24AT3G | Higher power rating (1500 W vs. 150 W), DO-214AC package (3.5 mm × 2.7 mm), 36.7 V clamping @ 41.7 A | Designed for higher-energy surge events (e.g., lightning-induced), not optimized for high-density board space or AOI | Select when system-level surge immunity > IEC 61000-4-5 Level 3 is required; not drop-in for NZ8P24VMX2WT5G footprint |
| ESD9X3.3SCT5G | Lower VRWM (3.3 V), 12 pF capacitance, SOD-923 package - intended for 3.3 V logic rails, not 24 V systems | Targeted at USB, HDMI, or mobile I/O protection; incompatible with 24 V automotive supply domains | Choose only for sub-5 V signal lines; cannot replace NZ8P24VMX2WT5G in 24 V ECU or IVN applications |
Compared with SZ1.5SM24AT3G and ESD9X3.3SCT5G, the NZ8P24VMX2WT5G uniquely balances compact X2DFNW2 packaging, 24 V system compatibility, and AEC-Q101 qualification - making it optimal for space-constrained, automotive-grade 24 V interface protection where low capacitance and AOI support are mandatory.

FAQ
What is the clamping voltage of NZ8P24VMX2WT5G at 1.0 A peak pulse current?
The NZ8P24VMX2WT5G has a clamping voltage of 35 V at 1.0 A peak pulse current (8/20 µs waveform). This value is measured under standardized transient conditions and ensures the protected circuit sees no more than 35 V during common ESD events. The NZ8P24VMX2WT5G maintains this performance across its full operating temperature range and is validated per IEC 61000-4-2 testing protocols.
Is NZ8P24VMX2WT5G qualified for automotive applications?
Yes, NZ8P24VMX2WT5G is AEC-Q101 qualified and PPAP capable. It meets the stress test requirements for automotive electronics, including temperature cycling, humidity bias, and ESD robustness. The "SZ" prefix variant (SZNZ8P24VMX2WT5G) is designated for automotive sites with enhanced process controls, but the NZ8P24VMX2WT5G itself carries full AEC-Q101 certification for use in ECUs and IVN systems.
What package type does NZ8P24VMX2WT5G use, and why is it significant?
NZ8P24VMX2WT5G uses the X2DFNW2 package (1.0 mm × 0.6 mm, Case 711BG), a wettable flank leadless design. This allows automated optical inspection (AOI) of solder joints - critical for zero-defect manufacturing in automotive PCB assembly. Its ultra-small footprint also enables high-density routing in tight ECU layouts where board space is constrained.
Does NZ8P24VMX2WT5G support bidirectional transient protection?
No, NZ8P24VMX2WT5G is a unidirectional Zener protection diode. It protects against positive transients on the cathode side relative to anode (ground). For bidirectional protection - such as on AC-coupled or differential lines - a separate device like the NUP4105MR6T1G or dual-rail configuration would be required. The NZ8P24VMX2WT5G datasheet explicitly specifies single-channel unidirectional operation.
What is the junction capacitance of NZ8P24VMX2WT5G, and how does it affect high-speed signals?
The junction capacitance of NZ8P24VMX2WT5G is 22 pF at 0 V bias and 1 MHz. This low value minimizes signal attenuation and timing skew on high-speed lines such as CAN FD or LIN, preserving signal integrity without requiring layout compensation. At 24 V operating voltage, the capacitance remains stable - ensuring consistent performance across nominal and fault conditions.
