Product details
Overview
MXDA3KP26CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning and ESD 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 (VC) at 71.2 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXDA3KP26CA datasheet, MXDA3KP26CA pinout, MXDA3KP26CA application, or MXDA3KP26CA 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 plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXDA3KP26CA is a bidirectional TVS diode array optimized for fast transient suppression in industrial and aerospace power rails. Its design supports dual-polarity surge handling without polarity-sensitive placement, with clamping action triggered at ≥28.9 V and limiting voltage to ≤42.1 V under 10/1000 µs 71.2 A pulses.
It meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and IEC61000-4-5 (lightning) standards across multiple source impedances. The device uses void-free UL94V-0 epoxy packaging, tin-lead or matte-tin terminations, and includes full wafer/lot traceability per high-reliability requirements.

FAQ
What is the clamping voltage of the MXDA3KP26CA under maximum rated surge conditions?
The MXDA3KP26CA exhibits a maximum clamping voltage (VC) of 42.1 V when subjected to its rated 10/1000 µs peak pulse current of 71.2 A. This value is measured per Figure 2 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The MXDA3KP26CA maintains this clamping performance across its full operating temperature range.
Is the MXDA3KP26CA suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, the MXDA3KP26CA is explicitly validated for IEC61000-4-5 Class 4 secondary lightning protection with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power rating and sub-5 ns response time meet the energy and timing requirements for Class 4 compliance without derating or parallel staging.
Does the MXDA3KP26CA have RoHS compliance and what does the 'e3' suffix indicate?
The MXDA3KP26CA carries the 'e3' suffix, indicating RoHS-compliant matte-tin plating on its terminations per J-STD-609. This ensures compatibility with lead-free reflow processes and eliminates hazardous substances per EU Directive 2011/65/EU. The device's UL94V-0 epoxy body and full lot traceability further support environmental and reliability compliance requirements.
How many TVS channels does the MXDA3KP26CA integrate and how are they configured?
The MXDA3KP26CA integrates two independent bidirectional TVS channels in a single 4-pin surface-mount package. Pins 1–2 form Channel 1 and Pins 3–4 form Channel 2, with odd-numbered pins designated as cathodes. This dual-channel architecture enables simultaneous protection of two signal or power lines-such as differential pairs or redundant supplies-without cross-talk or shared impedance effects.
What is the maximum operating temperature range for the MXDA3KP26CA?
The MXDA3KP26CA is rated for junction and storage temperatures from –55 °C to +150 °C, as specified in the Maximum Ratings table on page 2 of the RF01243 datasheet. This extended range supports deployment in under-hood automotive ECUs, downhole oilfield tools, and airborne avionics where thermal extremes are routine, and no derating is required within these limits.
