Product details
Overview
MXDA3KP8.0A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails and signal lines. It features 8.0 V reverse standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), 13.6 V maximum clamping voltage at 220.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXDA3KP8.0A datasheet, MXDA3KP8.0A pinout, MXDA3KP8.0A application, or MXDA3KP8.0A equivalent, key selection criteria include IEC61000-4-2/4-4/4-5 compliance, 10/1000 µs surge capability, RoHS-compliant e3 matte-tin plating, UL94V-0 molded package, and polarity-defined pin 1 marking for reliable PCB-level ESD and lightning surge suppression.
Technical Context
The MXDA3KP8.0A is a single-channel unidirectional TVS diode optimized for fast-clamping response (<100 ps rise time) and high-energy transient absorption. Its 3000 W peak pulse power rating at 10/1000 µs waveform enables robust protection against secondary lightning surges (IEC61000-4-5 Class 1–4 with 42 Ω source), EFT bursts, and ESD events per IEC61000-4-2.
It uses silicon avalanche technology with controlled breakdown characteristics, exhibits <50 µA standby current at VWM, and maintains stable clamping performance under thermal derating up to 150 °C. The device is wafer-lot traceable and surge-tested per lot, supporting high-reliability aerospace and industrial applications requiring MIL-PRF-19500 screening options.
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 |
|---|---|---|---|
| SMAJ8.0A | 600 W PPP rating, SMA package, 13.6 V VC @ 37.3 A IPP | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 3+ or 3000 W surges | Select MXDA3KP8.0A where full 3000 W surge immunity is required; SMAJ8.0A only for space-constrained, low-energy designs. |
| SMCJ8.0A | 1500 W PPP rating, SMC package, 13.6 V VC @ 110.3 A IPP | Half the peak power handling; requires parallel devices for equivalent 3000 W capability | MXDA3KP8.0A delivers rated 3000 W in single device; SMCJ8.0A needs two in parallel with matching layout, increasing BOM and footprint cost. |
Compared with SMAJ8.0A and SMCJ8.0A, MXDA3KP8.0A provides double the surge capacity of SMCJ8.0A and five times that of SMAJ8.0A in the same functional category-enabling single-device compliance with demanding IEC61000-4-5 Class 4 and MIL-STD-1275E load dump requirements.

FAQ
What is the clamping voltage of MXDA3KP8.0A at its rated peak pulse current?
The MXDA3KP8.0A has a maximum clamping voltage (VC) of 13.6 V at its rated peak pulse current (IPP) of 220.6 A under 10/1000 µs waveform conditions. This value is guaranteed across temperature and production lots, ensuring consistent overvoltage limiting in critical power rail protection applications where downstream ICs must remain below absolute maximum ratings.
Is MXDA3KP8.0A RoHS compliant and what plating does it use?
Yes, MXDA3KP8.0A is RoHS compliant and carries the "e3" designation indicating annealed matte-tin plating on its terminals. This plating meets MIL-STD-750 Method 2026 for solderability and ensures compatibility with lead-free reflow processes while maintaining low contact resistance and corrosion resistance over extended operational life.
Does MXDA3KP8.0A support MIL-PRF-19500 screening and what does that entail?
Yes, MXDA3KP8.0A supports optional MIL-PRF-19500 screening per Micronote 129, including wafer lot traceability, 3σ lot norm screening on standby current (ID), and conformance inspections. This enables qualification for high-reliability programs in aerospace and defense where parametric stability, burn-in, and failure analysis traceability are mandatory.
How does the polarity marking work on MXDA3KP8.0A?
MXDA3KP8.0A uses unidirectional polarity with odd-numbered pins designated as cathodes. Pin 1 is explicitly marked by a dot on the top surface of the package, and the device conducts from anode (Pin 2) to cathode (Pin 1) during overvoltage events. This marking aligns with JEDEC-standard orientation for vertical-mount TVS arrays and ensures correct PCB placement during automated assembly.
What is the moisture sensitivity level (MSL) of MXDA3KP8.0A and how does it affect handling?
MXDA3KP8.0A is rated MSL Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and requires no dry pack or baking prior to SMT assembly. This eliminates moisture-related popcorning risk during reflow and reduces manufacturing overhead-particularly valuable in high-volume industrial and telecom production environments.
