Product details
Overview
MXLDA3KP8.0CAE3 from Microsemi is a bidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection. It features a 8.0 V reverse standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), 13.6 V maximum clamping voltage at 220.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature. It is used in telecom line interfaces and industrial I/O protection.
For engineers reviewing the MXLDA3KP8.0CAE3 datasheet, MXLDA3KP8.0CAE3 pinout, MXLDA3KP8.0CAE3 application, or MXLDA3KP8.0CAE3 equivalent, key selection criteria include bidirectional polarity, 10/1000 µs surge rating, IEC61000-4-2/4-4/4-5 compliance, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXLDA3KP8.0CAE3 implements a dual-diode, center-tapped, bidirectional TVS structure enabling symmetrical clamping for AC-coupled signal lines. Its <100 ps response time ensures effective suppression of ESD events per IEC61000-4-2 and fast transients per IEC61000-4-4.
It is rated for 3000 W peak pulse power at 10/1000 µs waveform with 220.6 A IPP, and supports secondary lightning protection per IEC61000-4-5 under 42 Ω (Class 1–4), 12 Ω (Class 1–3), and 2 Ω (Class 2 only) source impedances - confirmed for MDA3KP8.0C variants in the reference document.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous operating voltage before clamping begins; matches 5 V or 3.3 V rail interfaces with safety margin. |
| V(BR) min/max | 8.89–9.83 V - Verified breakdown range at 1 mA; ensures predictable turn-on without premature conduction. |
| VC @ IPP | 13.6 V - Clamping voltage at 220.6 A peak pulse; limits downstream voltage stress during 10/1000 µs surges. |
| IPP | 220.6 A - Peak impulse current capability; supports IEC61000-4-5 Class 4 testing with 42 Ω source impedance. |
| PPP | 3000 W - Peak pulse power rating at 10/1000 µs; defines energy-handling capacity for transient suppression. |
| TJ range | –55 °C to +150 °C - Extended thermal operating envelope suitable for automotive under-hood and industrial control environments. |
| Polarity | Bidirectional - Enables protection of AC signals or differential buses without polarity constraints. |
Pinout & Package
MXLDA3KP8.0CAE3 uses a 3-pin SMD package (case outline per RF01243, Page 6) with void-free UL94V-0 epoxy body, matte-tin terminations, and pin 1 identified by a dot on top. Odd-numbered pins are cathodes per device polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of first TVS diode | Connects to protected line; forms one half of bidirectional clamp path with Pin 2 as common anode. |
| Pin 2 | Common anode | Center-tap node shared by both diodes; ties to system ground or reference plane for symmetrical clamping. |
| Pin 3 | Cathode of second TVS diode | Connects to complementary protected line (e.g., differential pair); completes bidirectional protection path. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping for AC-coupled or differential interfaces (e.g., RS-485, Ethernet PHY lines) without polarity alignment. |
| 3000 W 10/1000 µs rating | Meets IEC61000-4-5 Class 4 surge immunity requirements with 42 Ω source impedance in telecom and industrial equipment. |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ standby current screening, and extended environmental qualification. |
| RoHS-compliant e3 marking | Matte-tin plating meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity; no dry pack required for assembly. |
| Sub-100 ps response time | Clamps ESD events (IEC61000-4-2 ±8 kV contact) before sensitive ICs experience overstress, preserving signal integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | 600 W PPP rating, 10.0 V VC @ 62.7 A IPP - lower energy handling than MXLDA3KP8.0CAE3's 3000 W/13.6 V. | Suitable for consumer-grade I/O where Class 3 (not Class 4) IEC61000-4-5 compliance suffices. | Select SMBJ8.0CA only when surge threat level is reduced and PCB space is constrained (SMB vs. larger MDA package). |
| SMCJ8.0CA | 1500 W PPP, 12.0 V VC @ 125 A IPP - mid-tier power rating; smaller footprint than MDA but less robust than MXLDA3KP8.0CAE3. | Applicable in industrial controls needing Class 2–3 surge immunity but not full Class 4 validation. | Choose SMCJ8.0CA if cost and board area are prioritized over MIL-PRF-19500 upscreening and extreme reliability traceability. |
Compared with SMBJ8.0CA and SMCJ8.0CA, MXLDA3KP8.0CAE3 delivers 2× and 2× higher peak pulse power respectively, enables Class 4 lightning protection, and supports military-grade screening - making it optimal for mission-critical infrastructure where failure is not acceptable.

FAQ
What is the clamping voltage of MXLDA3KP8.0CAE3 at its rated peak pulse current?
The MXLDA3KP8.0CAE3 has a maximum clamping voltage (VC) of 13.6 V at its rated peak pulse current (IPP) of 220.6 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the RF01243 datasheet and ensures downstream circuitry remains within safe voltage limits during high-energy transients.
Is MXLDA3KP8.0CAE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP8.0CAE3 is RoHS compliant. The 'e3' suffix explicitly denotes matte-tin plating per JEDEC/IPC standards, confirming compliance with Directive 2011/65/EU. This plating also satisfies IPC/JEDEC J-STD-020B Level 1 moisture sensitivity, eliminating the need for dry packing prior to reflow soldering.
Can MXLDA3KP8.0CAE3 be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXLDA3KP8.0CAE3 is validated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as documented in the RF01243 datasheet Applications section. Its 3000 W peak pulse power and 220.6 A IPP rating meet the required energy threshold for this classification.
What is the standoff voltage and breakdown voltage range for MXLDA3KP8.0CAE3?
The MXLDA3KP8.0CAE3 has a rated reverse standoff voltage (VWM) of 8.0 V and a minimum-to-maximum breakdown voltage (V(BR)) range of 8.89 V to 9.83 V at 1 mA test current. This ensures reliable non-conduction during normal operation while guaranteeing consistent clamping onset under transient conditions.
Does MXLDA3KP8.0CAE3 support MIL-PRF-19500 upscreening and what does that entail?
Yes, MXLDA3KP8.0CAE3 supports optional MIL-PRF-19500 upscreening, including wafer and assembly lot traceability, 3σ screening on standby current (ID), and conformance inspections per Micronote 129. This makes MXLDA3KP8.0CAE3 suitable for defense, aerospace, and other high-reliability applications demanding rigorous quality assurance.
