Product details
Overview
MXLDA3KP14CAE3 from Microsemi is a bidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 14 V standoff voltage (VWM), 15.6–17.2 V breakdown voltage (V(BR)), and 23.2 V maximum clamping voltage (VC) at 129.4 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in telecom power interfaces.
For engineers reviewing the MXLDA3KP14CAE3 datasheet, MXLDA3KP14CAE3 pinout, MXLDA3KP14CAE3 application, or MXLDA3KP14CAE3 equivalent, this page delivers verified electrical parameters, package dimensions, IEC-compliant surge capability, polarity mapping, and RoHS-compliant sourcing details for high-reliability industrial and telecom designs.
Technical Context
The MXLDA3KP14CAE3 is a bidirectional TVS diode array designed for symmetric transient suppression across AC-coupled or differential signal/power lines. Its sub-5 ns response time enables effective clamping of ESD events (IEC61000-4-2 ±8 kV contact), EFT bursts (IEC61000-4-4), and lightning-induced surges (IEC61000-4-5 up to Class 4 with 42 Ω source).
It operates over –55 °C to +150 °C junction temperature, features void-free UL94V-0 epoxy packaging, tin-lead or matte-tin terminations, and meets MIL-PRF-19500 screening options for high-reliability applications. Standby leakage is ≤2 µA at 14 V, supporting low-power standby circuits without excessive quiescent drain.

FAQ
What is the clamping voltage of MXLDA3KP14CAE3 at its rated peak pulse current?
The MXLDA3KP14CAE3 has a maximum clamping voltage (VC) of 23.2 V at 129.4 A peak pulse current (IPP), measured under the standard 10/1000 µs double-exponential waveform. This value ensures protected circuits remain below critical voltage thresholds during high-energy transients, directly supporting IEC61000-4-5 compliance testing at multiple source impedances.
Is MXLDA3KP14CAE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP14CAE3 is RoHS compliant. The 'e3' suffix denotes matte-tin plating per JEDEC Standard J-STD-020, confirming lead-free terminations that meet EU Directive 2011/65/EU. This applies to both tin-lead and matte-tin variants, with e3 specifying the latter for compatibility with Pb-free soldering processes.
How is polarity defined for MXLDA3KP14CAE3 and how does it affect PCB layout?
MXLDA3KP14CAE3 is bidirectional, with odd-numbered pins (1 and 3) serving as cathodes and pin 2 as the common anode. This configuration requires pin 2 to be connected to system ground or reference plane, while pins 1 and 3 connect to protected lines. The dot marking on the package identifies pin 1, ensuring correct orientation during automated placement.
Can MXLDA3KP14CAE3 be used for IEC61000-4-5 Class 4 lightning surge testing?
Yes, MXLDA3KP14CAE3 is validated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as confirmed in the RF01243 datasheet. Its 3000 W peak pulse power rating and 23.2 V clamping voltage enable reliable operation under the 4 kV open-circuit test condition, provided layout minimizes parasitic inductance between the device and protected node.
What is the maximum operating temperature range for MXLDA3KP14CAE3 and how does it impact derating?
MXLDA3KP14CAE3 operates from –55 °C to +150 °C junction temperature. Per Figure 3 in RF01243, peak pulse power must be linearly derated above +25 °C: at +100 °C, only ~60% of the 3000 W rating remains usable. Designers must account for ambient temperature, power dissipation, and PCB copper area to maintain safe TJ during repeated surge events.
