Product details
Overview
NZ8P26VMX2WT5G from onsemi is a unidirectional Zener protection diode designed for ESD and transient overvoltage suppression in voltage-sensitive circuits. It features a 26 V working peak reverse voltage (VRWM), 33.8 V max breakdown voltage (VBR) at 5 mA, 38 V clamping voltage at 1.0 A (8/20 µs), 19 pF junction capacitance, and is housed in an ultra-compact X2DFNW2 (1.0 × 0.6 mm) wettable flank package - used in automotive ECUs and IVN interfaces.
For engineers reviewing the NZ8P26VMX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under ISO 10605/IEC 61000-4-2 stress, low leakage (<100 nA at 26 V), compact AOI-friendly packaging, 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 Zener-based clamping architecture delivers precise voltage limiting with 33.8 V maximum breakdown and 56 V clamping at 4.5 A (8/20 µs), while maintaining low 19 pF capacitance to minimize signal distortion in high-speed data lines.
Designed for automotive-grade reliability, it meets AEC-Q101 requirements and supports IEC 61000-4-2 ±30 kV (contact/air) and ISO 10605 ±30 kV (330 pF/330 Ω, 330 pF/2 kΩ, 150 pF/2 kΩ) ESD immunity. The X2DFNW2 package enables automated optical inspection via wettable flanks.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SZ1.5SM26AT3G | Higher power rating (1500 W vs. 200 W), larger SMC package (7.1 × 6.2 mm), 36.8 V VBR max | Used where higher surge energy absorption is required; not suitable for space-constrained IVN nodes | Select when >1 kA surge capability needed; avoid if board area <1 mm² available per channel |
| NSQA6V8AW5T2G | Lower VRWM (6.8 V), bidirectional configuration, 12 pF CJ, same X2DFNW2 package | Targeted at USB or low-voltage logic protection; incompatible with 26 V bias rails | Choose only for sub-10 V signal lines; cannot replace NZ8P26VMX2WT5G in 12/24 V automotive domains |
Compared with SZ1.5SM26AT3G and NSQA6V8AW5T2G, the NZ8P26VMX2WT5G uniquely balances 26 V system compatibility, ultra-compact size, and automotive qualification - making it optimal for space-limited, high-reliability IVN and ECU nodes where low capacitance and AOI support are mandatory.

FAQ
What is the maximum clamping voltage of the NZ8P26VMX2WT5G under a 4.5 A transient?
The NZ8P26VMX2WT5G exhibits a maximum clamping voltage of 56 V under an 8/20 µs 4.5 A pulse, as specified in its Electrical Characteristics table. This value defines the upper voltage limit imposed on protected circuitry during high-energy transients, ensuring downstream components remain within safe operating limits. The NZ8P26VMX2WT5G maintains this performance across its full operating temperature range.
Is the NZ8P26VMX2WT5G qualified for automotive applications?
Yes, the NZ8P26VMX2WT5G is AEC-Q101 qualified and PPAP capable, with a junction temperature range of −55°C to +150°C. It is explicitly intended for automotive ECU and IVN applications, and its datasheet confirms compliance with ISO 10605 and IEC 61000-4-2 ESD standards. The "SZ" prefix variant (SZNZ8P26VMX2WT5G) further denotes automotive-specific site and control requirements.
What does the "X2DFNW2" package designation mean for the NZ8P26VMX2WT5G?
The X2DFNW2 package for the NZ8P26VMX2WT5G is a 2-terminal, ultra-compact flat no-lead design measuring 1.0 mm × 0.6 mm with 0.65 mm pitch and wettable flanks. Case number 711BG confirms its standardized footprint. This package enables high-density placement and automated optical inspection - critical for automotive PCB assembly - while minimizing parasitic inductance for effective transient response.
How does the NZ8P26VMX2WT5G differ from standard Zener diodes used for voltage regulation?
Unlike general-purpose Zener diodes optimized for DC voltage reference, the NZ8P26VMX2WT5G is engineered specifically for transient suppression: it prioritizes fast response, high peak pulse current (4.5 A), low clamping overshoot, and robust ESD ratings (±30 kV). Its 19 pF capacitance and AEC-Q101 qualification further distinguish it from regulation-focused Zeners, which typically lack surge ratings and automotive validation.
Can the NZ8P26VMX2WT5G be used in bidirectional signal lines like CAN bus?
No - the NZ8P26VMX2WT5G is a unidirectional device intended for DC-biased lines (e.g., 12 V or 24 V supply rails or single-ended sensor outputs). For bidirectional differential lines such as CAN, a symmetric bidirectional TVS like NSQA6V8AW5T2G would be required. Using the NZ8P26VMX2WT5G on a true bidirectional line risks forward conduction during negative transients and inadequate protection.
