Product details
Overview
MXLDA3KP10CA from Microsemi is a bidirectional 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 (VC) at 176.4 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXLDA3KP10CA datasheet, MXLDA3KP10CA pinout, MXLDA3KP10CA application, or MXLDA3KP10CA equivalent, this device is selected for IEC61000-4-5 Class 1–4 surge immunity with 42 Ω/12 Ω source impedance, EFT/ESD suppression per IEC61000-4-4/4-2, and robust 10/1000 μs transient handling in telecom DC power feeds and motor drive control inputs.
Technical Context
The MXLDA3KP10CA implements a bidirectional avalanche diode structure optimized for fast response (<5 ns) and low clamping ratio (VC/VWM ≈ 1.7). Its design targets high-energy transients in ungrounded or floating systems where polarity-agnostic protection is required, such as AC-coupled signal lines or dual-rail DC bus monitoring.
It complies with MIL-PRF-19500 screening options for high-reliability applications and undergoes full lot-level surge testing per 10/1000 μs waveform. The device's 3σ standby current screening and Level 1 moisture sensitivity ensure stable performance in reflow-soldered industrial assemblies without dry-pack requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous operating voltage before conduction begins; sets minimum system overvoltage threshold for protection activation. |
| V(BR) min–max | 11.1–12.3 V - Breakdown occurs within this range at 1 mA; ensures predictable turn-on margin above VWM. |
| VC @ IPP | 17.0 V at 176.4 A - Clamped voltage during 10/1000 μs surge; limits downstream IC stress to safe levels under worst-case transients. |
| PPP | 3000 W - Peak pulse power rating at 10/1000 μs; defines energy-handling capability for lightning-induced surges. |
| ID @ VWM | 5 μA - Standby leakage at rated standoff; negligible power loss in always-on protection circuits. |
| TJ/TSTG | –55 °C to +150 °C - Extended thermal range enables use in under-hood automotive modules and industrial enclosures without derating. |
| Response time | <5 ns - Bidirectional avalanche turn-on speed; protects against sub-microsecond ESD events per IEC61000-4-2. |
Pinout & Package
MXLDA3KP10CA uses a 3-pin SMD package (case outline per RF01243, Page 6) with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by dot marking for Pin 1. Odd-numbered pins are cathodes per internal TVS pair configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Reference terminal for first bidirectional TVS element; connects to protected line requiring symmetrical clamping. |
| Pin 2 | Anode/Cathode Common | Center tap shared between two TVS elements; forms differential or common-mode protection node in 3-pin array layout. |
| Pin 3 | Cathode of Channel 2 | Reference terminal for second bidirectional TVS element; enables dual-line or split-rail protection topology. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetrical clamping on AC-coupled or floating lines without polarity biasing circuitry. |
| 3000 W peak pulse power (10/1000 μs) | Supports IEC61000-4-5 Class 4 immunity with 42 Ω source impedance in telecom power entry designs. |
| MIL-PRF-19500 screening option | Provides wafer/assembly lot traceability and 3σ ID screening for aerospace and defense-grade reliability assurance. |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost and process risk. |
| Clamping ratio VC/VWM = 1.7 | Minimizes voltage overshoot during surge events, protecting 12 V-rated interface ICs such as RS-485 transceivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Lower PPP (600 W), same VWM (10 V), SMB package (smaller footprint, lower thermal mass). | Suitable for board-level ESD only; not rated for IEC61000-4-5 Class 3/4 lightning surges. | Select SMBJ10CA only when peak surge current remains below 43 A and PCB space is constrained. |
| SMCJ10CA | Same PPP (3000 W), identical VWM/VC specs, but SMC package (larger than MXLDA3KP10CA, different pad layout). | Compatible for same surge classes but requires PCB redesign due to larger body and different lead pitch. | Choose SMCJ10CA if existing SMC footprint is standardized and MIL-PRF-19500 screening is not required. |
Compared with SMBJ10CA and SMCJ10CA, MXLDA3KP10CA delivers identical 3000 W surge capability in a smaller, high-reliability package with optional military screening-making it optimal for space-constrained, mission-critical industrial power interfaces where traceability and thermal robustness are mandatory.

FAQ
What is the clamping voltage of MXLDA3KP10CA at its rated peak pulse current?
The MXLDA3KP10CA 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 guaranteed per the manufacturer's electrical characteristics table and defines the upper voltage limit imposed on protected circuitry during surge events. The MXLDA3KP10CA maintains this clamping performance across its full operating temperature range.
Is MXLDA3KP10CA suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXLDA3KP10CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power and 17.0 V clamping voltage enable compliance in telecom and industrial power entry applications. MXLDA3KP10CA meets this requirement without derating at 25 °C.
Does MXLDA3KP10CA require dry-pack handling or baking before reflow soldering?
No, MXLDA3KP10CA has IPC/JEDEC J-STD-020B Level 1 moisture sensitivity and does not require dry-pack packaging or pre-reflow baking. Its void-free thermosetting epoxy body and moisture-resistant construction eliminate moisture-related popcorning risk during standard lead-free reflow profiles. This simplifies manufacturing flow and reduces cost versus higher MSL-rated TVS devices.
How does the bidirectional configuration of MXLDA3KP10CA affect its circuit placement?
The bidirectional configuration of MXLDA3KP10CA allows placement across any two nodes where symmetrical overvoltage protection is needed-such as AC signal lines, floating DC rails, or transformer center taps-without regard to polarity. Pin 1 and Pin 3 serve as cathodes, with Pin 2 as the common node. This eliminates external biasing components required by unidirectional TVS arrays and simplifies layout in differential or isolated systems.
What is the meaning of the "C" suffix in MXLDA3KP10CA?
The "C" suffix in MXLDA3KP10CA denotes bidirectional polarity, as defined in the Part Nomenclature section of the RF01243 datasheet. It distinguishes this variant from unidirectional versions like MXLDA3KP10A. The MXLDA3KP10CA uses an internal back-to-back diode configuration to provide equal clamping in both voltage polarities, making it suitable for AC-coupled or floating applications where voltage reversals occur.
