Product details
Overview
MXLDA3KP30CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount 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)), and 48.4 V maximum clamping voltage (VC) at 62 A peak pulse current.
For engineers reviewing the MXLDA3KP30CAE3 datasheet, MXLDA3KP30CAE3 pinout, MXLDA3KP30CAE3 application, or MXLDA3KP30CAE3 equivalent, this device serves as a RoHS-compliant, MIL-PRF-19500 upscreenable TVS for industrial power interfaces, telecom line cards, and automotive body control modules requiring robust surge immunity with sub-5 ns response time and ±30 V symmetric clamping.
Technical Context
The MXLDA3KP30CAE3 implements a bidirectional avalanche diode structure enabling symmetrical clamping for AC-coupled or floating signal lines. Its 10/1000 μs waveform rating of 3000 W defines its energy-handling capability under standardized surge conditions, while its <5 ns response time ensures effective suppression of fast transients including ESD and EFT.
It operates across –55 °C to +150 °C junction temperature, supports 260 °C soldering per MIL-STD-750 Method 2026, and maintains ≤2 μA standby current at 30 V VWM - critical for low-power monitoring circuits where leakage must not disrupt bias integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V - Maximum continuous operating voltage before clamping begins; matches 24 V nominal DC systems with safety margin. |
| V(BR) min/max | 33.3–36.8 V - Confirmed avalanche onset range at 1 mA; ensures predictable turn-on without premature conduction. |
| VC @ IPP | 48.4 V at 62 A - Clamping voltage during 10/1000 μs surge; limits downstream IC stress to safe levels. |
| PPP | 3000 W - Peak pulse power handling per IEC61000-4-5; enables Class 1–4 secondary lightning protection. |
| Response time | <5 ns - Time from 0 V to V(BR) min; captures ESD events faster than most interface ICs can react. |
| ID @ VWM | ≤2 μA - Standby leakage at rated standoff; preserves battery life and reference stability in always-on circuits. |
| TJ/TSTG | –55 to +150 °C - Full military-grade temperature range; validated for under-hood automotive and industrial outdoor enclosures. |
Pinout & Package
MXLDA3KP30CAE3 uses a 3-pin surface-mount package (case outline per RF01243 Page 6) with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by a dot marking indicating Pin 1. Odd-numbered pins are cathodes per internal dual-diode configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connects to protected line side; forms one half of bidirectional clamp path with Pin 2. |
| Pin 2 | Anode/Common | Shared anode node; referenced to ground or system common; establishes symmetrical clamping behavior. |
| Pin 3 | Cathode of Channel 2 | Connects to same protected line as Pin 1; completes dual-cathode, single-anode bidirectional topology. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping on AC or floating lines without polarity constraints - eliminates need for external series diodes. |
| 3000 W 10/1000 μs rating | Validated surge capacity meets IEC61000-4-5 Class 4 (42 Ω source) for telecom and industrial port protection. |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and wafer-level conformance inspection. |
| Moisture sensitivity Level 1 | No dry pack required per J-STD-020B - simplifies SMT assembly and reduces handling overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30CA | 600 W PPP rating, SMA package, 48.4 V VC at 10.3 A IPP - lower energy handling and smaller footprint. | Best suited for board space-constrained consumer electronics with lower surge threat levels (IEC61000-4-2 only). | Select when cost and size outweigh need for full IEC61000-4-5 Class 4 compliance. |
| SMCJ33CA | 1500 W PPP rating, SMC package, 53.3 V VC at 28.3 A IPP - mid-tier power handling with larger thermal mass than SMAJ but less than MDA. | Appropriate for industrial PLC I/O modules requiring Class 3 lightning protection with moderate layout flexibility. | Choose when balancing PCB area, thermal performance, and Class 3 surge requirements without MIL-spec screening needs. |
Compared with SMAJ30CA and SMCJ33CA, MXLDA3KP30CAE3 delivers double the peak pulse power (3000 W vs. 1500/600 W), supports MIL-PRF-19500 upscreening, and maintains stable clamping down to –55 °C - making it uniquely suitable for aerospace, defense, and high-end industrial systems demanding verified reliability under extreme surge and thermal stress.

FAQ
What is the clamping voltage of MXLDA3KP30CAE3 at its rated peak pulse current?
The MXLDA3KP30CAE3 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 per standard test methods and guarantees that downstream circuitry sees no more than 48.4 V during worst-case surge events - critical for protecting 3.3 V, 5 V, and 24 V logic and interface ICs. The MXLDA3KP30CAE3 achieves this with consistent performance across its full operating temperature range.
Is MXLDA3KP30CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXLDA3KP30CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with a 42 Ω source impedance, as confirmed in the manufacturer's application guidance (RF01243 Rev B, Page 1). Its 3000 W peak pulse power rating and 48.4 V clamping voltage at 62 A enable compliance without derating in ambient temperatures up to 100 °C. The MXLDA3KP30CAE3 also supports Class 4 under 12 Ω and 2 Ω source impedances per documented test configurations.
What does the "C" suffix in MXLDA3KP30CAE3 indicate?
The "C" in MXLDA3KP30CAE3 denotes bidirectional polarity - meaning the device provides symmetrical clamping for both positive and negative transients on the same line pair. This eliminates the need for external polarity management and makes MXLDA3KP30CAE3 ideal for AC-coupled interfaces like RS-485, CAN, or telecom tip/ring lines. The "e3" suffix confirms RoHS compliance with lead-free terminations, and the full MXLDA3KP30CAE3 designation maps to Microsemi's standardized nomenclature for high-reliability TVS arrays.
Does MXLDA3KP30CAE3 require moisture-sensitive handling per J-STD-020?
No, MXLDA3KP30CAE3 is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry packing or baking prior to reflow. This simplifies manufacturing logistics and eliminates yield loss from moisture-related popcorning. The MXLDA3KP30CAE3 achieves this via void-free thermosetting epoxy encapsulation and process-controlled assembly - a key advantage over higher-MSL competitors requiring strict floor-life management.
Can MXLDA3KP30CAE3 replace unidirectional TVS diodes in existing designs?
MXLDA3KP30CAE3 is not a drop-in replacement for unidirectional TVS diodes due to its bidirectional architecture and dual-cathode/single-anode pinout. While it offers superior protection for AC or floating lines, substituting it for a unidirectional device (e.g., MDA3KP30AE3) requires verifying that the protected circuit does not rely on DC bias polarity for proper clamping behavior. Always validate layout, grounding, and system-level surge paths before integrating MXLDA3KP30CAE3 into legacy unidirectional designs.
