Product details
Overview
MXDA3KP11A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. It features 11 V standoff voltage (VWM), 12.2–13.5 V breakdown range (V(BR)), 18.2 V max clamping voltage at 164.8 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXDA3KP11A datasheet, MXDA3KP11A pinout, MXDA3KP11A application, or MXDA3KP11A equivalent, key selection criteria include IEC61000-4-5 Class 1–4 secondary lightning compliance with 42 Ω/12 Ω/2 Ω source impedances, 100 ps response time, RoHS-compliant void-free epoxy package, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXDA3KP11A is a single-channel unidirectional TVS diode optimized for fast clamping of high-energy transients in DC power rails and signal lines. Its 10/1000 μs surge rating of 3000 W and sub-100 ps response enable protection against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and induced switching surges.
It uses silicon avalanche junction technology with defined polarity (Pin 1 = cathode), requires no dry pack per J-STD-020B Level 1 moisture sensitivity, and supports solder reflow up to 260 °C. Standby leakage is limited to 5 μA at 11 V, ensuring minimal system power loss during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 12.2–13.5 V @ 1 mA - Confirmed avalanche onset range for reliable triggering margin |
| VC @ IPP | 18.2 V @ 164.8 A - Clamped voltage during full 3000 W 10/1000 μs surge, limiting downstream stress |
| IPP | 164.8 A - Peak impulse current supported under standard 10/1000 μs waveform |
| ID @ VWM | 5 μA - Low standby leakage ensures minimal quiescent power draw in always-on systems |
| TJ/TSTG | –55 to +150 °C - Extended thermal range enables deployment in harsh industrial and aerospace environments |
| Response time | <100 ps - Near-instantaneous turn-on prevents transient energy from reaching protected ICs |
Pinout & Package
MXDA3KP11A uses a 2-pin surface-mount DO-214AB (SMC) package with void-free UL94V-0 epoxy body, matte-tin plating, and polarity marked by dot indicating Pin 1 (cathode). Weight ≈5 g; moisture sensitivity level = 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts surge current to ground when V > V(BR) |
| Pin 2 | Anode | Typically tied to system ground; completes low-impedance path for transient energy dissipation |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables robust protection against severe lightning-induced surges per IEC61000-4-5 with 42 Ω source impedance |
| Unidirectional configuration | Prevents reverse-bias leakage in DC-powered circuits while allowing forward conduction only during overvoltage events |
| MIL-PRF-19500 upscreening option | Supports high-reliability qualification for defense/aerospace programs requiring lot traceability and 3σ ID screening |
| RoHS-compliant e3 marking | Meets environmental compliance requirements without compromising surge performance or thermal stability |
| 100% surge tested | Each unit validated to withstand full-rated 3000 W transient, ensuring field reliability in mission-critical applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | 600 W rating, SMB package, 18.2 V VC @ 32.4 A IPP | Limited to lower-energy transients; not rated for IEC61000-4-5 Class 4 with 42 Ω source | Select when board space is constrained and surge threat level is ≤1 kV (10/1000 μs) |
| 1.5KE11A | Through-hole DO-201 package, same 11 V VWM, but 17.1 V VC @ 175 A IPP | Requires wave soldering; incompatible with automated SMT assembly | Choose for legacy through-hole designs where rework tolerance and mechanical robustness outweigh SMT efficiency |
Compared with SMBJ11A and 1.5KE11A, MXDA3KP11A delivers 5× higher peak power handling in an SMT package with verified Class 4 lightning immunity, making it optimal for new industrial designs demanding both miniaturization and extreme surge resilience.

FAQ
What is the clamping voltage of MXDA3KP11A at its rated peak pulse current?
The MXDA3KP11A has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPP) of 164.8 A under 10/1000 μs waveform conditions. This value is measured per standard test methods and guarantees predictable voltage limiting during surge events, directly protecting downstream components such as gate drivers and communication ICs connected to the same rail as MXDA3KP11A.
Is MXDA3KP11A suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXDA3KP11A is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the official Microsemi datasheet RF01243 Rev B. Its 3000 W peak pulse power rating and 18.2 V clamping voltage ensure compliance without external derating, making MXDA3KP11A appropriate for critical infrastructure interfaces where Class 4 immunity is mandated.
Does MXDA3KP11A require dry pack packaging per J-STD-020B?
No, MXDA3KP11A is classified as Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it does not require dry pack packaging or floor life controls prior to reflow. This simplifies handling and storage logistics, and allows standard SMT assembly processes without baking or humidity-controlled environments - a key advantage for high-volume manufacturing of systems using MXDA3KP11A.
What is the polarity configuration of MXDA3KP11A, and how is it marked?
MXDA3KP11A is a unidirectional TVS diode with Pin 1 designated as the cathode, marked by a dot on the top surface of the DO-214AB package. This polarity must be observed during PCB layout to ensure correct orientation relative to the protected line (cathode toward the line, anode toward ground), otherwise the device will not conduct during overvoltage events and MXDA3KP11A will fail to provide intended protection.
Can MXDA3KP11A be used in bidirectional signal line protection?
No, MXDA3KP11A is strictly unidirectional and unsuitable for bidirectional AC or differential signal lines. For such applications, the bidirectional variant MDA3KP11CA (with 'C' suffix) must be selected. Using MXDA3KP11A on bidirectional paths risks forward conduction during normal signal swings, leading to distortion or latch-up - confirming that MXDA3KP11A functions only as a DC-rail protector with defined polarity.
