Product details
Overview
MXLDA3KP26CA 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 and ESD/EFT protection. 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 from –55 °C to +150 °C.
For engineers reviewing the MXLDA3KP26CA datasheet, MXLDA3KP26CA pinout, MXLDA3KP26CA application, or MXLDA3KP26CA equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, 100 ps response time, RoHS-compliant e3 matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXLDA3KP26CA is a bidirectional TVS diode array optimized for fast transient suppression in industrial and aerospace power rails. Its construction enables symmetrical clamping in both polarities, with <5 ns response time and full surge testing per 10/1000 µs waveform.
It supports secondary lightning protection per IEC61000-4-5 across multiple source impedances (42 Ω, 12 Ω, 2 Ω), delivering defined Class 1–4 performance for MDA3KP6.0CA–MDA3KP18A and Class 1–3 for MDA3KP26CA variants - confirming MXLDA3KP26CA's Class 1–3 applicability under 12 Ω impedance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 26 V - Maximum continuous DC or peak AC operating voltage before clamping begins |
| V(BR) min/max | 28.9–31.9 V @ 1 mA - Ensures reliable turn-on above system operating voltage with margin |
| VC @ IPP | 42.1 V @ 71.2 A - Clamped voltage during worst-case 10/1000 µs surge, limiting downstream stress |

| RoHS | e3 matte-tin plating - Compliant with lead-free soldering and environmental regulations |
Pinout & Package
MXLDA3KP26CA uses a DO-214AB (SMC) surface-mount package with two terminals: Cathode (Pin 1) and Anode (Pin 2). Polarity is marked by a dot on the package top; odd-numbered pins are cathodes per Microsemi's standard TVS polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | High-side reference terminal | Connected to protected line; conducts during positive transients relative to Pin 2 |
| Pin 2 (Anode) | Low-side reference terminal | Connected to ground or return path; conducts during negative transients relative to Pin 1 |
Key Features

|---|---|
| Bidirectional clamping | Enables symmetric overvoltage protection on AC lines or floating buses without polarity constraints |
| MIL-PRF-19500 screening option | Supports high-reliability qualification for aerospace and defense programs requiring lot traceability and 3σ ID screening |
| Level 1 moisture sensitivity | No dry pack required per J-STD-020B - simplifies handling and eliminates bake-out prior to reflow |
| 100% surge tested | Each unit validated at rated PPP ensures field reliability under real-world surge conditions |
| UL94V-0 epoxy body | Self-extinguishing encapsulation meets flammability requirements for safety-critical enclosures |
Applications

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 | 600 W PPP rating, same VWM and bidirectional configuration, DO-214AA package | Limited to lower-energy transients; not qualified for IEC61000-4-5 Class 3 with 12 Ω source | Select when surge energy is ≤600 W and cost sensitivity outweighs MIL screening needs |
| SMCJ26CA | 1500 W PPP, identical DO-214AB package, same VWM and RoHS e3 plating | Half the peak pulse power; insufficient for Class 3 lightning per 12 Ω source impedance | Choose for space-constrained designs needing partial protection where full 3000 W is not mandated |
Compared with SMBJ26CA and SMCJ26CA, MXLDA3KP26CA delivers double the pulse power of SMCJ26CA and five times that of SMBJ26CA - enabling verified compliance with IEC61000-4-5 Class 3 lightning testing using 12 Ω source impedance, while retaining DO-214AB footprint compatibility.

FAQ
What is the clamping voltage of MXLDA3KP26CA at its rated peak pulse current?
The MXLDA3KP26CA has a maximum clamping voltage (VC) of 42.1 V at its rated peak pulse current (IPP) of 71.2 A under 10/1000 µs waveform conditions. This value is guaranteed per the manufacturer's electrical characteristics table and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is MXLDA3KP26CA suitable for IEC61000-4-5 Class 3 lightning testing?
Yes, MXLDA3KP26CA is explicitly rated for IEC61000-4-5 Class 3 secondary lightning protection when tested with a 12 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power and 42.1 V clamping enable compliance without derating.
Does MXLDA3KP26CA require dry packing per J-STD-020B?
No, MXLDA3KP26CA has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it does not require dry pack or baking prior to surface-mount reflow. The device's void-free UL94V-0 epoxy body contributes to this robust moisture resistance.
What is the polarity configuration of MXLDA3KP26CA?
MXLDA3KP26CA is a bidirectional TVS, indicated by the "C" suffix in its nomenclature. It provides symmetrical clamping for both positive- and negative-going transients across its two terminals, making it ideal for AC-coupled or floating-bus protection without polarity concerns.
Can MXLDA3KP26CA be used in aerospace applications requiring MIL-PRF-19500 screening?
Yes, optional MIL-PRF-19500 upscreening is available for MXLDA3KP26CA, including wafer and assembly lot traceability, 3σ standby current screening, and conformance inspections. This makes it suitable for flight-critical avionics and defense platforms requiring documented high-reliability qualification.
