Product details
Overview
MXLDA3KP6.5CAE3 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 6.5 V standoff voltage (VWM), 7.22–7.98 V breakdown range (V(BR)), and clamps to ≤11.2 V at 267.9 A peak pulse current (IPP).
For engineers reviewing the MXLDA3KP6.5CAE3 datasheet, MXLDA3KP6.5CAE3 pinout, MXLDA3KP6.5CAE3 application, or MXLDA3KP6.5CAE3 equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, RoHS-compliant matte-tin plating, MIL-PRF-19500 upscreening eligibility, and compatibility with IEC-classified lightning surge environments requiring sub-100 ns response.
Technical Context
The MXLDA3KP6.5CAE3 implements a symmetrical avalanche diode structure enabling bidirectional clamping without external polarity constraints. Its <100 ps response time ensures effective suppression of ESD events and fast-rising transients, while its 10/1000 µs waveform-rated 3000 W peak pulse power supports robust Class 1–4 secondary lightning protection under defined source impedances.
It operates across –55 °C to +150 °C junction temperature, with moisture sensitivity level (MSL) 1 - eliminating dry-pack requirements per IPC/JEDEC J-STD-020B. Standby leakage is limited to ≤500 µA at 6.5 V VWM, and forward clamping remains ≤4.0 V at 500 A for unidirectional test conditions (not applicable to this bidirectional variant).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5CA | 600 W PPP rating (vs. 3000 W); same VWM and bidirectional polarity | Not suitable for IEC61000-4-5 Class 3/4; limited to lower-energy ESD/EFT only | Select when board space is constrained and surge threat level is ≤600 W |
| 1.5KE6.8C | Through-hole DO-201 package; 1500 W PPP; higher clamping voltage (11.5 V) | Requires through-hole assembly; less effective for high-speed ESD due to parasitic inductance | Choose for legacy through-hole designs where rework to SMD is impractical |
Compared with SMBJ6.5CA and 1.5KE6.8C, MXLDA3KP6.5CAE3 delivers five-fold higher surge power handling and superior high-frequency transient response in an SMD package qualified for high-reliability screening - making it optimal for mission-critical industrial and telecom surge protection where energy levels exceed 1000 W.

FAQ
What does the 'C' in MXLDA3KP6.5CAE3 indicate?
The 'C' suffix in MXLDA3KP6.5CAE3 denotes bidirectional polarity - meaning the device provides symmetrical clamping voltage in both directions across its two terminals. This enables use on AC-coupled lines, differential data paths, or any application where voltage polarity reversal must be tolerated without external diode pairing. MXLDA3KP6.5CAE3 achieves this via a back-to-back avalanche diode configuration within a single DO-214AB package.
Is MXLDA3KP6.5CAE3 compliant with RoHS and REACH?
Yes, MXLDA3KP6.5CAE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its nomenclature, indicating lead-free matte-tin plating per EU Directive 2011/65/EU. It also meets REACH SVHC requirements. The device contains no intentionally added substances restricted under either regulation, and its UL94V-0 epoxy body is halogen-free per Microsemi's material declarations.
Can MXLDA3KP6.5CAE3 be used for primary lightning protection?
No, MXLDA3KP6.5CAE3 is rated for secondary lightning protection per IEC61000-4-5 only - meaning it protects against induced surges coupled onto internal wiring after a direct strike has been handled by upstream Type I/II SPDs. Its 3000 W rating and 10/1000 µs waveform capability are insufficient for direct exposure to lightning currents; primary protection requires coordinated multi-stage architectures with gas discharge tubes or MOV-based front-end stages.
What is the maximum allowable junction temperature for MXLDA3KP6.5CAE3?
The maximum junction temperature (TJ) for MXLDA3KP6.5CAE3 is +150 °C, with a minimum of –55 °C. This range is validated across all electrical parameters in the datasheet and supports operation in harsh environments such as engine compartments, industrial enclosures, and outdoor telecom cabinets. Derating of peak pulse power begins above 25 °C, following the curve in Figure 3 of RF01243 Rev B.
Does MXLDA3KP6.5CAE3 require PCB layout considerations beyond standard SMD practices?
Yes - to preserve its <100 ps response, keep trace lengths between MXLDA3KP6.5CAE3 and protected nodes under 5 mm, minimize loop area, and avoid vias in the main current path. Use solid ground planes beneath the device and route protected lines directly to its pins. Avoid placing bypass capacitors or ferrites between the TVS and the threat entry point, as they degrade clamping speed. Thermal relief on pads should be minimized to ensure low-inductance mounting.
