Product details
Overview
MXLDA3KP11CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD protection. It features a 11 V reverse standoff voltage (VWM), 12.2–13.5 V breakdown voltage (V(BR)), 18.2 V maximum clamping voltage (VC) at 164.8 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXLDA3KP11CAE3 datasheet, MXLDA3KP11CAE3 pinout, MXLDA3KP11CAE3 application, or MXLDA3KP11CAE3 equivalent, key selection criteria include bidirectional surge handling per IEC61000-4-5 (42 Ω/12 Ω source), sub-5 ns response time, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXLDA3KP11CAE3 is a monolithic dual-diode TVS array configured in a center-tap common-cathode arrangement for bidirectional line-to-line and line-to-ground protection. Its silicon avalanche structure delivers <5 ns response time and clamps transients up to 3000 W under 10/1000 µs waveform with no degradation after full-rated surge events.
It supports IEC61000-4-2 (ESD ±30 kV air/±30 kV contact), IEC61000-4-4 (EFT 4 kV), and IEC61000-4-5 (lightning surge up to Class 4 with 42 Ω source impedance). Standby leakage is ≤5 µA at 11 V, and junction temperature derating begins above 25 °C per Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous DC or RMS operating voltage before conduction begins |
| V(BR) min/max | 12.2–13.5 V @ 1 mA - Ensures reliable avalanche initiation across process variation |
| VC @ IPP | 18.2 V @ 164.8 A - Limits protected circuit voltage during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients without failure |
| ID @ VWM | ≤5 µA - Minimizes standby power loss and signal loading in high-impedance lines |
| TJ/TSTG | –55 to +150 °C - Enables deployment in automotive under-hood, industrial motor drives, and aerospace avionics |
Pinout & Package
MXLDA3KP11CAE3 uses a DO-214AB (SMC) plastic package with void-free UL94V-0 epoxy body, matte-tin-plated terminals, and polarity defined by a dot marking indicating Pin 1 (cathode of first diode). Weight ≈5 g; moisture sensitivity level = 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Diode 1 | Common cathode connection for bidirectional configuration; ties to system ground or reference plane |
| Pin 2 | Anode of Diode 1 / Cathode of Diode 2 | Center-tap node - connects to protected line (e.g., RS-485 A/B, USB D+/D−) |
| Pin 3 | Anode of Diode 2 | Second cathode path to ground; completes symmetrical clamping for differential or single-ended signals |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables symmetric protection on AC-coupled or differential data lines without polarity constraints |
| 3000 W peak pulse power | Handles multi-kW surges from lightning-induced coupling or inductive switching without thermal runaway |
| <5 ns response time | Clamps ESD events faster than typical IC input structures can be damaged |
| MIL-PRF-19500 screening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and surge testing per military standard |
| RoHS-compliant e3 marking | Meets global environmental compliance with annealed matte-tin plating compatible with lead-free reflow |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | 600 W PPP rating; 17.0 V VC @ 33.2 A; DO-214AA package | Limited to lower-energy surges (e.g., board-level ESD only); not rated for IEC61000-4-5 Class 4 | Select when cost-sensitive designs require basic ESD/EFT protection without lightning-level energy handling. |
| SMCJ11CA | 1500 W PPP rating; 18.2 V VC @ 82.4 A; same DO-214AB package | Half the peak pulse power; suitable for Class 2–3 IEC61000-4-5 but not Class 4 with 42 Ω source | Choose where space-constrained layouts demand identical footprint but system surge threat level is moderate. |
Compared with MXLDA3KP11CAE3, SMBJ11CA offers lower cost and smaller size but cannot sustain 3000 W surges, while SMCJ11CA shares the DO-214AB footprint and clamping voltage but delivers only half the energy absorption-making MXLDA3KP11CAE3 essential for mission-critical lightning-prone environments.

FAQ
What is the clamping voltage of MXLDA3KP11CAE3 at its rated peak pulse current?
The MXLDA3KP11CAE3 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 and defines the upper voltage limit imposed on protected circuits during surge events. The low VC ensures downstream components like RS-485 transceivers or microcontroller I/O remain within absolute maximum ratings.
Is MXLDA3KP11CAE3 suitable for IEC61000-4-5 Class 4 lightning surge testing?
Yes, MXLDA3KP11CAE3 is validated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance. Its 3000 W peak pulse power rating and 18.2 V clamping voltage enable it to safely divert the 4 kV open-circuit test voltage without failure. Data sheet Table on Page 3 confirms MDA3KP11CA (identical to MXLDA3KP11CAE3) is explicitly listed for Class 4 under 42 Ω conditions.
Does MXLDA3KP11CAE3 have RoHS compliance and what does the 'e3' suffix indicate?
The 'e3' suffix in MXLDA3KP11CAE3 denotes full RoHS compliance per Directive 2011/65/EU, with annealed matte-tin plating on all terminals. This ensures compatibility with lead-free reflow soldering profiles up to 260 °C for 10 seconds and eliminates hexavalent chromium, cadmium, mercury, lead, PBB, and PBDE substances. The device meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack requirements.
How many diodes are integrated in MXLDA3KP11CAE3 and how are they configured?
MXLDA3KP11CAE3 integrates two avalanche diodes in a bidirectional center-tap configuration: Pin 1 is the cathode of Diode 1, Pin 2 is the shared anode/cathode node (center tap), and Pin 3 is the anode of Diode 2. This arrangement enables symmetrical clamping between any two pins - ideal for protecting differential buses like RS-485 or USB - without requiring separate unidirectional devices or external biasing.
Can MXLDA3KP11CAE3 replace older MDA3KP11CA parts without layout changes?
Yes, MXLDA3KP11CAE3 is a direct replacement for MDA3KP11CA with identical electrical specifications, DO-214AB package dimensions, pinout, and thermal characteristics. The 'MXL' prefix reflects updated manufacturing and traceability protocols, while 'e3' confirms RoHS compliance - both enhancements fully backward-compatible with legacy MDA3KP11CA designs and PCB footprints.
