Product details
Overview
MXLDA3KP30CA 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 protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT protection per IEC61000-4-4. It features a 30 V reverse standoff voltage (VWM), 33.3–36.8 V breakdown voltage (V(BR)), 48.4 V maximum clamping voltage at 62 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXLDA3KP30CA datasheet, MXLDA3KP30CA pinout, MXLDA3KP30CA application, or MXLDA3KP30CA equivalent, this device serves as a high-power, bidirectional surge protector for telecom interfaces, industrial control inputs, and DC power rail protection where fast response (<5 ns), low standby leakage (<2 µA), and MIL-PRF-19500 upscreening capability are required.
Technical Context
The MXLDA3KP30CA is a monolithic dual-diode TVS array configured in a common-cathode arrangement for bidirectional clamping across two terminals. Its silicon avalanche structure delivers sub-5 ns response time and clamps transients up to 3000 W under 10/1000 µs waveform conditions.
It supports secondary lightning protection classes 1–4 with 42 Ω source impedance, classes 1–3 with 12 Ω, and class 2 only with 2 Ω source impedance - all validated per IEC61000-4-5. Standby current is limited to ≤2 µA at 30 V, and thermal derating follows a defined curve down to zero power at +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V - Maximum continuous DC or peak AC voltage the device blocks without clamping |
| V(BR) min/max | 33.3–36.8 V @ 1 mA - Ensures reliable avalanche initiation above operating voltage with margin |
| VC @ IPP | 48.4 V @ 62 A - Limits downstream voltage stress during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients typical of lightning-induced surges |
| ID @ VWM | ≤2 µA - Minimizes power loss and signal distortion in always-on protection circuits |
| TJ/TSTG | –55 to +150 °C - Enables deployment in harsh industrial, aerospace, and outdoor environments |
| Response time | <5 ns - Clamps ESD events before sensitive circuitry sustains damage |
Pinout & Package
MXLDA3KP30CA uses a DO-214AB (SMC) plastic package with void-free thermosetting epoxy body (UL94V-0), matte-tin-plated terminals, and polarity marked by a dot indicating Pin 1 (cathode). Weight ≈5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Common cathode node for bidirectional clamping path; connects to system ground or reference plane |
| Pin 2 | Anode | Input/output line terminal; clamps positive or negative transients to cathode reference |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines or floating DC buses without polarity constraints |
| 3000 W peak pulse power | Handles high-energy surges from lightning coupling or inductive switching without failure |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and conformance inspection |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life limitations for automated assembly |
| Low clamping ratio (VC/VWM = 1.61) | Provides tighter voltage limiting than typical TVS devices, reducing stress on downstream ICs |
Applications
| Telecom Line Interface Protection | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protects RS-485/RS-232 data lines in base stations and remote terminal units against induced surges from nearby lightning strikes. IC Role / Device Role / Timing Role: Bidirectional TVS array clamping differential-mode transients between A/B lines and ground.

IC Role / Device Role / Timing Role: Standoff-rated TVS shunting transient energy to chassis ground before reaching input optocoupler or Schmitt trigger. Use Value: Prevents false triggering and latch-up with 48.4 V clamping ceiling, well below 30 V input stage absolute maximum rating. |
| DC Power Rail Surge Suppression | Automotive Body Control Module Inputs |
Use Scenario: Installed across 24 V battery-fed subsystem rails (e.g., infotainment, ADAS sensors) to absorb load dump and alternator ripple spikes. IC Role / Device Role / Timing Role: High-power unidirectional/bidirectional clamp absorbing 3000 W pulses without degradation over 1000+ events. Use Value: Extends system lifetime by preventing cumulative oxide damage in downstream DC-DC converters and LDOs. | Use Scenario: Protects LIN bus or switch inputs in body control modules exposed to ISO 7637-2 Pulse 1/2a/3a and IEC61000-4-5 surges. IC Role / Device Role / Timing Role: Fast-response TVS suppressing ESD and coupled transients before reaching automotive-grade microcontrollers. Use Value: Meets AEC-Q101 stress test requirements when combined with optional MIL-PRF-19500 screening. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | 600 W PPP rating, SMB package, 48.4 V VC @ 12.3 A IPP | Limited to lower-energy surges; unsuitable for IEC61000-4-5 Class 4 or lightning coupling | Select when board space is constrained and surge threat level is ESD/EFT-only |
| 1.5KE30CA | Through-hole DO-201 package, same 30 V VWM and 48.4 V VC, but 1500 W PPP | Requires PCB through-holes; lower energy handling limits use in high-exposure telecom or industrial locations | Choose for legacy through-hole designs where rework to SMT is not feasible |
Compared with SMBJ30CA and 1.5KE30CA, MXLDA3KP30CA delivers double the peak pulse power of the former and twice the energy capacity of the latter - enabling robust protection in high-threat environments without layout or thermal redesign.

FAQ
What is the clamping voltage of MXLDA3KP30CA at its rated peak pulse current?
The MXLDA3KP30CA has a maximum clamping voltage (VC) of 48.4 V at 62 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is measured across the device terminals during standardized surge testing and defines the upper voltage limit imposed on protected circuitry during transient events.
Is MXLDA3KP30CA RoHS compliant?
Yes, MXLDA3KP30CA is RoHS compliant, indicated by the "e3" suffix in its full marking per Microsemi's nomenclature. The device uses annealed matte-tin plating and void-free UL94V-0 epoxy packaging, meeting EU Directive 2011/65/EU requirements without exemptions.
Does MXLDA3KP30CA support MIL-PRF-19500 screening?
Yes, MXLDA3KP30CA supports optional MIL-PRF-19500 upscreening with conformance inspections including wafer lot traceability, 3σ screening on standby current (ID), and extended environmental testing. Screening must be specified at order entry and is performed per Micronote 129 guidelines.
What is the polarity configuration of MXLDA3KP30CA?
MXLDA3KP30CA is a bidirectional TVS array with a common-cathode configuration. Pin 1 is the cathode terminal, and Pin 2 is the anode terminal; the "C" in the part number explicitly denotes bidirectional functionality per Microsemi's naming convention.
Can MXLDA3KP30CA be used for IEC61000-4-5 Class 4 lightning protection?
Yes, MXLDA3KP30CA is qualified 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 48.4 V clamping voltage ensure compliance with the 4 kV test level under this configuration.
