Product details
Overview
MXLDA3KP26AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 26 V standoff voltage (VWM), 28.9–31.9 V breakdown voltage (V(BR)), and 42.1 V clamping voltage (VC) at 71.2 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in industrial power supplies.
For engineers reviewing the MXLDA3KP26AE3 datasheet, MXLDA3KP26AE3 pinout, MXLDA3KP26AE3 application, or MXLDA3KP26AE3 equivalent, key selection criteria include its 26 V working voltage, 42.1 V clamping performance at 71.2 A, RoHS-compliant e3 plating, -55°C to +150°C operating range, and verified 3000 W surge capability under 10/1000 µs waveform.
Technical Context
This TVS array uses silicon avalanche diode technology optimized for fast response (<100 ps rise time) and high-energy absorption in compact surface-mount packages. Its unidirectional polarity ensures DC-biased circuit protection with cathode-defined pin 1 marking and low standby leakage (≤2 µA at 26 V).
Designed for compliance with IEC61000-4-5 (secondary lightning), IEC61000-4-2 (ESD ±30 kV air), and IEC61000-4-4 (EFT 4 kV), it delivers stable clamping across temperature with derated pulse power above 25°C per Figure 3 and meets MIL-PRF-19500 screening options upon request.

FAQ
What is the clamping voltage of MXLDA3KP26AE3 at its rated peak pulse current?
The MXLDA3KP26AE3 has a maximum clamping voltage (VC) of 42.1 V at 71.2 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is measured per standardized test method and ensures predictable overvoltage limiting during surge events, directly supporting design margin calculations for downstream MOSFETs and controllers.
Is MXLDA3KP26AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP26AE3 is RoHS compliant. The 'e3' suffix denotes matte-tin plating on the terminals, qualified for lead-free reflow soldering per IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required-and compatible with standard assembly processes used in high-volume industrial manufacturing.
Does MXLDA3KP26AE3 meet IEC61000-4-5 for secondary lightning protection?
Yes, MXLDA3KP26AE3 is validated for secondary lightning protection per IEC61000-4-5 with 42 Ω source impedance across Class 1–4, and with 12 Ω and 2 Ω sources for specified classes. Its 3000 W PPP rating and 42.1 V clamping performance ensure compliance without external derating or additional components.
What is the polarity configuration and pin identification method for MXLDA3KP26AE3?
MXLDA3KP26AE3 is a unidirectional TVS array with cathode on odd-numbered pins. Pin 1 is identified by a dot marking on the top surface of the package, and the device must be oriented so that Pin 1 connects to the line being protected and Pin 2 to system ground for proper clamping operation.
Can MXLDA3KP26AE3 be used in automotive applications requiring AEC-Q200 qualification?
MXLDA3KP26AE3 itself is not AEC-Q200 qualified; however, Microsemi offers upscreened versions compliant with MIL-PRF-19500 that are commonly accepted in automotive body control and powertrain applications where AEC-Q200 is not mandated but high-reliability screening is required. Always verify qualification status with the latest Microchip product documentation for MXLDA3KP26AE3.
