Product details
Overview
MXLDA3KP26CAE3 from Microsemi (now Microchip) is a bidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD/EFT protection in industrial power interfaces. It features a 26 V reverse standoff voltage (VWM), 28.9–31.9 V breakdown voltage (V(BR)), 42.1 V maximum clamping voltage at 71.2 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXLDA3KP26CAE3 datasheet, MXLDA3KP26CAE3 pinout, MXLDA3KP26CAE3 application, or MXLDA3KP26CAE3 equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, RoHS-compliant matte-tin plating, and UL94V-0 void-free epoxy packaging suitable for automated SMT assembly.
Technical Context
The MXLDA3KP26CAE3 implements a monolithic dual-diode (bidirectional) avalanche structure optimized for sub-5 ns response time and low clamping ratio (VC/V(BR) ≈ 1.37). Its 10/1000 μs surge rating of 3000 W enables robust protection against inductive switching transients and induced RF energy in DC power rails and signal lines.
Designed for MIL-PRF-19500 upscreening eligibility, it includes wafer-level lot traceability, 3σ screening on standby current (ID ≤ 2 μA @ 26 V), and moisture sensitivity level 1 per J-STD-020B-eliminating dry-pack requirements and supporting standard reflow profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 26 V - Maximum continuous DC or peak AC operating voltage before clamping initiates |
| V(BR) min/max | 28.9–31.9 V @ 1 mA - Confirmed avalanche onset range ensuring predictable turn-on margin above VWM |
| VC @ IPP | 42.1 V @ 71.2 A - Clamping voltage during full 3000 W 10/1000 μs surge, limiting downstream voltage stress |
| IPP | 71.2 A - Peak impulse current supported at rated clamping voltage, directly tied to IEC61000-4-5 Class 4 capability with 42 Ω source |
| ID @ VWM | ≤2 μA - Ultra-low leakage ensures minimal power loss and no interference with high-impedance sensing circuits |
| TJ/TSTG | –55 °C to +150 °C - Extended thermal range supports operation in harsh environments including motor drives and outdoor telecom equipment |
| Package | DO-214AB (SMC) - Standardized surface-mount outline with 21.03 × 22.05 mm body, compatible with IPC-7351B land patterns |
Pinout & Package
MXLDA3KP26CAE3 uses the DO-214AB (SMC) package: a rectangular, void-free thermosetting epoxy body (UL94V-0), matte-tin plated terminals, and polarity defined by a dot marking indicating Pin 1 (cathode for unidirectional variants; symmetric bidirectional configuration here).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (1–2) | Bidirectional TVS terminals | Interchangeable terminals-no polarity dependency; conducts equally in both directions above V(BR) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetrical overvoltage clamping on AC-coupled or floating DC lines without polarity concerns |
| 3000 W peak pulse power (10/1000 μs) | Meets IEC61000-4-5 Class 4 with 42 Ω source impedance-critical for industrial Ethernet and PLC backplane protection |
| RoHS-compliant e3 marking | Matte-tin plating ensures lead-free solder compatibility and eliminates tin whisker risk in long-life deployments |
| MIL-PRF-19500 upscreening option | Supports high-reliability qualification for aerospace and defense systems requiring lot traceability and 3σ ID screening |
| Moisture Level 1 (J-STD-020B) | Zero dry-pack requirement simplifies handling, storage, and reflow-reducing manufacturing overhead and BOM cost |
Applications

Use Value: Eliminates false triggering and ADC offset drift caused by microamp-level leakage in precision measurement subsystems. |
Use Scenario: DC power input protection for remote radio units mounted on cell towers subject to lightning-induced surges. IC Role / Device Role / Timing Role: High-temperature-rated (TJ = +150 °C) TVS sustaining full 3000 W rating at elevated ambient temperatures. Use Value: Maintains specified clamping performance without derating in sealed enclosures where internal temperatures exceed 100 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ26CA | Lower PPP rating (600 W), smaller SMB package (5.3 × 4.1 mm), same VWM and bidirectional polarity | Limited to IEC61000-4-5 Class 2 (42 Ω); unsuitable for Class 4 or high-energy inductive loads | Select when board space is constrained and surge energy is ≤600 W-verify clamping voltage margin at reduced IPP |
| SMCJ26CA | Same DO-214AB package and 3000 W rating, but higher VC (45.7 V @ 65.6 A) and wider V(BR) tolerance (28.9–34.2 V) | Higher clamping voltage reduces protection margin for 3.3 V/5 V logic; tighter V(BR) spread of MXLDA3KP26CAE3 improves design predictability | Prefer MXLDA3KP26CAE3 for designs requiring lowest possible VC and tightest V(BR) control-especially in safety-critical systems |
Compared with SMBJ26CA and SMCJ26CA, MXLDA3KP26CAE3 delivers superior clamping voltage consistency (42.1 V max), tighter breakdown voltage spread (28.9–31.9 V), and verified MIL-PRF-19500 upscreening path-making it optimal for high-reliability industrial and telecom infrastructure where surge margin and long-term stability are non-negotiable.

FAQ
What does the 'C' suffix in MXLDA3KP26CAE3 indicate?
The 'C' suffix denotes bidirectional polarity-meaning MXLDA3KP26CAE3 provides symmetrical clamping for both positive and negative transients without requiring orientation during placement. This is confirmed in Microsemi's part nomenclature guide (RF01243 Rev B, p.2), where 'C' explicitly defines bidirectional construction across the MDA3KPxxC family.
Is MXLDA3KP26CAE3 compliant with IEC61000-4-5 Class 4 testing?
Yes-MXLDA3KP26CAE3 meets IEC61000-4-5 Class 4 requirements when tested with a 42 Ω source impedance, as documented in the Applications/Benefits section (p.1) and validated by its 71.2 A IPP rating at 42.1 V clamping. It also supports Class 4 with 12 Ω and 2 Ω sources per the same specification.
What is the maximum clamping voltage of MXLDA3KP26CAE3 and under what test condition?
The maximum clamping voltage of MXLDA3KP26CAE3 is 42.1 V, measured at 71.2 A peak pulse current (IPP) under the standardized 10/1000 μs double-exponential waveform, as specified in the Electrical Characteristics table (p.3) of the official datasheet RF01243 Rev B.
Does MXLDA3KP26CAE3 require dry-pack handling per J-STD-020B?
No-MXLDA3KP26CAE3 is rated Moisture Sensitivity Level 1 (MSL-1) per J-STD-020B, meaning it has unlimited floor life and requires no dry-pack storage or baking prior to reflow. This is explicitly stated in the Mechanical and Packaging section (p.2) of RF01243 Rev B.
What package type does MXLDA3KP26CAE3 use and what are its key mechanical dimensions?
MXLDA3KP26CAE3 uses the DO-214AB (SMC) package: a surface-mount outline with body dimensions of 21.03–22.05 mm length × 6.86–7.87 mm width × 8.64–9.65 mm height, per the Package Dimensions table (p.6) in RF01243 Rev B. The terminals are matte-tin plated and solderable per MIL-STD-750 Method 2026.
