Product details
Overview
MXLDA3KP6.0CAE3 from Microsemi is a bidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. It features a 6.0 V reverse standoff voltage (VWM), 6.67–7.37 V breakdown voltage (V(BR)), 10.3 V maximum clamping voltage (VC) at 291.3 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXLDA3KP6.0CAE3 datasheet, MXLDA3KP6.0CAE3 pinout, MXLDA3KP6.0CAE3 application, or MXLDA3KP6.0CAE3 equivalent, key selection criteria include bidirectional polarity, IEC61000-4-5 Class 1–4 compliance with 2/12/42 Ω source impedance, 10/1000 µs surge rating, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transient overvoltages within nanoseconds-<5 ns response for bidirectional operation-enabling protection against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5). Its unidirectional/bidirectional variants are distinguished by part-number suffix 'A' (unidirectional) or 'C' (bidirectional), with MXLDA3KP6.0CAE3 explicitly designated as bidirectional per nomenclature and electrical test conditions.
The device is rated for 3000 W peak pulse power at 10/1000 µs waveform, with clamping performance validated at 291.3 A IPP and 10.3 V VC. Standby leakage remains ≤1000 µA at 6.0 V VWM, 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 | 6.0 V - Maximum continuous DC or RMS operating voltage before conduction begins |
| V(BR) min/max | 6.67–7.37 V @ I(BR) - Ensures reliable avalanche initiation across process variation and temperature |
| VC @ IPP | 10.3 V @ 291.3 A - Clamped voltage during worst-case 10/1000 µs surge; defines protected circuit's max stress level |
| PPP | 3000 W @ 10/1000 µs - Peak surge energy handling capacity under standard lightning waveform |
| ID @ VWM | ≤1000 µA - Low leakage preserves signal integrity and minimizes standby power loss |

Pinout & Package
MXLDA3KP6.0CAE3 is housed in a void-free transfer-molded thermosetting epoxy package (UL94V-0), with tin-lead or matte-tin-plated terminals solderable per MIL-STD-750 Method 2026. Pin 1 is marked by a dot on the top surface; odd-numbered pins are cathodes per internal diode configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Reference point for bidirectional clamping; connects to protected line side |
| Pin 2 | Anode of Channel 1 | Common ground reference for first TVS channel; ties to system GND plane |
| Pin 3 | Cathode of Channel 2 | Second protected line connection; enables dual-line or differential pair protection |
| Pin 4 | Anode of Channel 2 | Shared anode with Pin 2 in common-anode configuration; reduces layout complexity |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetrical clamping on AC signals or bidirectional data lines without polarity-aware routing |

| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and wafer-level conformance inspection |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing overhead |
| Clamp time <5 ns | Responds faster than most microcontrollers and FPGAs can be damaged, preserving downstream IC integrity |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package | Lower surge capacity limits use to Class 2/3 IEC61000-4-5; unsuitable for 3000 W primary protection zones | Select when space-constrained layouts require smaller footprint and surge demands are ≤600 W |
| SMCJ6.0CA | 1500 W PPP rating, same VWM and polarity, DO-214AB package, higher VC (10.5 V) | Meets Class 2–3 IEC61000-4-5 but not Class 4; requires verification for 291 A peak current scenarios | Choose for cost-sensitive designs where 1500 W margin suffices and DO-214AB mechanical fit is required |
Compared with SMBJ6.0CA and SMCJ6.0CA, MXLDA3KP6.0CAE3 delivers double the surge energy handling of SMCJ6.0CA and five times that of SMBJ6.0CA-enabling single-device protection for high-energy zones like AC mains entry or telecom power feeds without parallel staging.

FAQ
What does the 'C' suffix in MXLDA3KP6.0CAE3 indicate?
The 'C' suffix in MXLDA3KP6.0CAE3 explicitly denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients. This is confirmed in Microsemi's RF01243 Rev B datasheet, page 2 ("Part Nomenclature") and electrical tables, where only 'C'-suffixed parts are listed with bidirectional test conditions and dual-channel clamping behavior. MXLDA3KP6.0CAE3 is not pin-compatible with unidirectional variants like MXLDA3KP6.0AE3.
Is MXLDA3KP6.0CAE3 RoHS compliant?
Yes, MXLDA3KP6.0CAE3 is RoHS compliant, as indicated by the 'e3' suffix in the full part number. Per Microsemi RF01243 Rev B datasheet page 2, 'e3' specifies annealed matte-tin plating meeting EU RoHS Directive 2011/65/EU. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and is qualified for lead-free reflow up to 260 °C for 10 seconds.
What is the maximum clamping voltage VC for MXLDA3KP6.0CAE3 and under what test condition?
The maximum clamping voltage VC for MXLDA3KP6.0CAE3 is 10.3 V, measured at a peak pulse current (IPP) of 291.3 A under the standardized 10/1000 µs double-exponential surge waveform. This value is specified in the Electrical Characteristics table (page 3) of RF01243 Rev B and defines the upper voltage limit imposed on protected circuits during worst-case transient events.
Can MXLDA3KP6.0CAE3 be used for IEC61000-4-5 Class 4 lightning protection?
Yes, MXLDA3KP6.0CAE3 is rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as documented in the Applications/Benefits section (page 1) of RF01243 Rev B. Its 3000 W PPP rating and 291.3 A IPP capability meet the 4 kV/2 Ω, 2 kV/12 Ω, and 1 kV/42 Ω Class 4 test levels without derating at 25 °C.
What is the junction temperature range for MXLDA3KP6.0CAE3?
The junction and storage temperature range for MXLDA3KP6.0CAE3 is –55 °C to +150 °C, as specified in the Maximum Ratings table (page 2) of RF01243 Rev B. This wide range supports operation in extreme environments such as under-hood automotive electronics, outdoor base stations, and industrial motor control cabinets where ambient temperatures exceed 100 °C.
