Product details
Overview
MXLDA3KP11CA 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 11 V reverse standoff voltage (VWM), 12.2–13.5 V breakdown voltage (V(BR)), 18.2 V maximum clamping voltage at 164.8 A peak pulse current, and operates from –55 °C to +150 °C. Used in telecom AC/DC front-ends and motor drive I/O protection.
For engineers reviewing the MXLDA3KP11CA datasheet, MXLDA3KP11CA pinout, MXLDA3KP11CA application, or MXLDA3KP11CA equivalent, key selection criteria include bidirectional clamping capability, 10/1000 µs surge rating, IEC61000-4-5 Class 1–4 compliance with 2–42 Ω source impedance, and RoHS-compliant void-free epoxy packaging.
Technical Context
The MXLDA3KP11CA implements a monolithic dual-diode anti-parallel configuration enabling symmetrical clamping for AC-coupled or floating signal lines. Its sub-5 ns response time ensures effective suppression of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and induced RF transients without signal distortion.
Rated for 3000 W peak pulse power at 10/1000 µs waveform, it delivers 164.8 A IPP with 18.2 V VC while maintaining ≤5 µA ID at 11 V VWM. The device meets MIL-PRF-19500 screening options when upscreened and supports full lot traceability per wafer and assembly batch.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous operating voltage before clamping initiates; matches 12 V nominal rail systems with margin. |
| V(BR) min/max | 12.2–13.5 V - Confirmed breakdown range at 1 mA; ensures predictable turn-on across temperature and process variation. |
| VC @ IPP | 18.2 V at 164.8 A - Clamping voltage under 10/1000 µs surge; limits downstream IC stress below 20 V absolute max. |
| PPP | 3000 W - Peak pulse power handling capacity; sustains single-event surges per IEC61000-4-5 Level 4 (42 Ω source). |
| ID @ VWM | 5 µA - Standby leakage at rated standoff; negligible power loss in always-on monitoring circuits. |
| TJ/TSTG | –55 to +150 °C - Full industrial temperature range; enables deployment in motor drives and outdoor base stations. |
| Polarity | Bidirectional - Symmetric clamping for AC signals or ungrounded data lines; no polarity dependency in layout. |
Pinout & Package
MXLDA3KP11CA uses a 2-pin SMD package (case outline per Page 6 of RF01243 Rev B) with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and pin 1 identified by a dot on top. Odd-numbered pins are cathodes - in this 2-pin bidirectional device, Pin 1 and Pin 2 form a symmetric anti-parallel diode pair.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of D1 / Cathode of D2 | Forms one terminal of the bidirectional clamp; connects to protected line (e.g., RS-485 A or CAN H). |
| Pin 2 | Cathode of D1 / Anode of D2 | Forms complementary terminal; ties to reference plane (e.g., ground or common-mode node) with minimal inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or floating differential buses (e.g., RS-485, CAN, Ethernet PHY) without polarity constraints. |
| 3000 W 10/1000 µs rating | Meets IEC61000-4-5 Class 4 with 42 Ω source for secondary lightning; validated per Figure 1 and Table on Page 3. |
| Sub-5 ns response time | Clamps ESD events (IEC61000-4-2 ±8 kV contact) before sensitive logic thresholds are exceeded. |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and conformance inspection. |
| Moisture Level 1 (J-STD-020B) | Eliminates dry-pack requirement and bake-out prior to reflow; reduces manufacturing cost and risk of popcorning. |
Applications
| Industrial Motor Drive I/O Protection | Telecom AC/DC Power Entry |
|---|---|

Use Value: Limits let-through voltage to <20 V during 42 Ω IEC61000-4-5 Class 4 test, protecting downstream OVP comparators and controllers. |
| Outdoor Wireless Base Station RF Front-End | Industrial PLC Analog Input Module |
Use Scenario: Shielding antenna port LNA inputs and bias tees from induced RF energy and ESD during field maintenance. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp shunting fast transients to RF ground without degrading VSWR. Use Value: Maintains <0.5 dB insertion loss up to 2.5 GHz while suppressing ±15 kV ESD per IEC61000-4-2. |
Use Scenario: Guarding 4–20 mA current loop inputs against wiring errors, ground faults, and electrostatic discharge in factory-floor environments. IC Role / Device Role / Timing Role: Standoff-rated TVS placed across input terminals to clamp overvoltage before precision op-amp input stage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11CA | Lower PPP (400 W), smaller SMA package, 18.2 V VC at 22.5 A IPP - not suitable for IEC61000-4-5 Class 4. | Limited to low-energy ESD/EFT in consumer-grade sensors; cannot replace MXLDA3KP11CA in telecom or industrial power entry. | Select only where surge energy is <500 W and board space is constrained; verify clamping margin with actual system impedance. |
| SMCJ11CA | Same 3000 W rating and 18.2 V VC, but SMC package (larger footprint, higher thermal mass); identical electrical specs per DO-214AB outline. | Compatible in high-power industrial controls where PCB real estate allows larger SMC footprint and higher mounting reliability is required. | Drop-in alternative if SMC pad layout exists; same electrical performance but requires mechanical redesign for MXLDA3KP11CA's smaller case. |
Compared with SMAJ11CA and SMCJ11CA, MXLDA3KP11CA offers identical clamping performance to SMCJ11CA but in a more compact, high-reliability molded package with MIL-PRF-19500 upscreening support - making it preferred for aerospace-adjacent and mission-critical infrastructure where traceability and surge margin are non-negotiable.

FAQ
What is the clamping voltage of MXLDA3KP11CA at its rated peak pulse current?
The MXLDA3KP11CA 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 guaranteed across temperature and process variation per the Electrical Characteristics table on Page 3 of RF01243 Rev B and defines the upper voltage limit imposed on protected circuitry during surge events.
Is MXLDA3KP11CA RoHS compliant?
Yes, MXLDA3KP11CA is RoHS compliant, indicated by the "e3" suffix in its full marking per Page 2 of RF01243 Rev B. The device uses annealed matte-tin or tin-lead plating and void-free UL94V-0 epoxy, meeting EU Directive 2011/65/EU requirements without exemptions.
Can MXLDA3KP11CA be used for IEC61000-4-5 Class 4 lightning surge testing?
Yes, MXLDA3KP11CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as confirmed in the Applications/Benefits section on Page 1 of RF01243 Rev B. Its 3000 W peak pulse power and 18.2 V clamping ensure compliance when properly mounted with low-inductance grounding.
What is the standoff voltage rating of MXLDA3KP11CA, and how does it relate to system design?
MXLDA3KP11CA has a reverse standoff voltage (VWM) of 11 V, meaning it remains non-conductive up to this peak voltage under normal operation. System designers select it for 12 V nominal rails where 11 V VWM provides sufficient margin above steady-state voltage while allowing rapid clamping during overvoltage events.
Does MXLDA3KP11CA require moisture sensitivity level (MSL) baking before reflow soldering?
No, MXLDA3KP11CA is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and no bake-out is required prior to reflow. This eliminates process steps, reduces cost, and prevents thermal stress damage during assembly - confirmed in the Features section on Page 1.
