Product details
Overview
MXDA3KP10A 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 a 10 V reverse standoff voltage (VWM), 11.1–12.3 V breakdown voltage (V(BR)), 17.0 V maximum clamping voltage at 176.4 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXDA3KP10A datasheet, MXDA3KP10A pinout, MXDA3KP10A application, or MXDA3KP10A equivalent, key selection criteria include IEC61000-4-5 Class 1–4 secondary lightning compliance with 42 Ω source impedance, 10/1000 μs surge rating, RoHS-compliant e3 matte-tin plating, and polarity-defined cathode pin assignment per package marking.
Technical Context
The MXDA3KP10A functions as a fast-response, high-energy clamping device optimized for protecting DC power rails and signal lines against transient overvoltages. Its sub-100 ps response time enables suppression of ESD per IEC61000-4-2 and EFT per IEC61000-4-4, while its 3000 W peak pulse power rating supports robust immunity to inductive switching transients and induced RF energy.
It is rated for 10 V working standoff voltage and clamps to ≤17.0 V at 176.4 A (10/1000 μs waveform), delivering precise voltage limiting without forward conduction under normal operation. Polarity is defined by odd-numbered pins as cathodes, and the device undergoes full lot surge testing and 3σ standby current screening per MIL-PRF-19500 high-reliability protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |

| TJ/TSTG | –55 °C to +150 °C - Enables deployment in harsh environments including automotive engine bays and industrial motor drives |
Pinout & Package
MXDA3KP10A uses a 3-pin surface-mount plastic package (case outline per Page 6, RF01243 Rev B) with void-free UL94V-0 epoxy body, tin-lead or annealed matte-tin (e3) plating, and polarity indicated by dot marking for Pin 1. Odd-numbered pins are cathodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line; clamps positive transients to ground when referenced to Pin 2 |
| Pin 2 | Anode / Common Ground Reference | Shared low-impedance return path for all channels; must be routed with minimal inductance |
| Pin 3 | Cathode of Channel 2 | Independent clamping node for dual-rail or differential protection; electrically isolated from Pin 1 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | 600 W PPP rating; 10.0–11.1 V V(BR); DO-214AC package; 2-pin single channel | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 4 or 3000 W surge events | Select SMAJ10A only for cost-sensitive, space-constrained designs with <1 kW surge exposure. |
| SMCJ10A | 1500 W PPP rating; 10.0–11.1 V V(BR); DO-214AB package; 2-pin single channel | Half the energy handling of MXDA3KP10A; requires two devices for dual-rail protection | Choose SMCJ10A when board area allows discrete placement and surge threat level is limited to Class 2 per IEC61000-4-5. |
Compared with SMAJ10A and SMCJ10A, the MXDA3KP10A delivers double the surge energy capacity of SMCJ10A and five times that of SMAJ10A in a single 3-pin package with dual-channel architecture-enabling compact, high-reliability protection for mission-critical 24–48 V systems without layout duplication or thermal stacking.

FAQ
What is the clamping voltage of MXDA3KP10A at its rated peak pulse current?
The MXDA3KP10A has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPP) of 176.4 A under 10/1000 μs waveform conditions. This value is measured per standard test methods in the RF01243 datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MXDA3KP10A maintains this clamping performance across its full operating temperature range.
Is MXDA3KP10A RoHS compliant and what plating does it use?
Yes, MXDA3KP10A is RoHS compliant, indicated by the "e3" suffix in its full part marking per Microsemi nomenclature. It uses annealed matte-tin plating on terminals, which meets MIL-STD-750 Method 2026 for solderability and supports both SnPb and lead-free reflow profiles up to 260 °C for 10 seconds. This plating ensures consistent wetting and intermetallic formation in high-volume manufacturing.
How is polarity defined on the MXDA3KP10A package?
Polarity on the MXDA3KP10A is defined by pin numbering: odd-numbered pins (Pin 1 and Pin 3) are cathodes, while Pin 2 serves as the common anode/reference terminal. A dot marking on the top surface identifies Pin 1. This configuration enables dual-channel unidirectional protection-each cathode-anode pair clamps positive transients on separate lines referenced to the shared anode.
Does MXDA3KP10A meet IEC61000-4-5 Class 4 lightning surge requirements?
Yes, MXDA3KP10A is rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B. Its 3000 W peak pulse power rating and 17.0 V clamping voltage at 176.4 A ensure compliance under the 4 kV test level, making it suitable for unprotected outdoor interfaces and long cable runs in industrial settings.
What is the maximum junction temperature rating for MXDA3KP10A?
The MXDA3KP10A has a specified junction and storage temperature range of –55 °C to +150 °C, per Absolute Maximum Ratings on Page 2 of RF01243 Rev B. This extended range supports operation in high-ambient environments such as engine compartments, power converter heatsinks, and enclosed outdoor enclosures-without derating until ambient exceeds 125 °C, per the Figure 3 derating curve.
