Product details
Overview
MXLDA3KP20AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 20 V standoff voltage (VWM), 22.2–24.5 V breakdown voltage (V(BR)), and 32.4 V clamping voltage (VC) at 92.6 A peak pulse current (IPP). 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 power supply input stages.
For engineers reviewing the MXLDA3KP20AE3 datasheet, MXLDA3KP20AE3 pinout, MXLDA3KP20AE3 application, or MXLDA3KP20AE3 equivalent, key selection criteria include its 20 V working voltage, 32.4 V clamping performance at 92.6 A, RoHS-compliant e3 plating, -55°C to +150°C operating junction temperature, and MIL-PRF-19500 upscreening capability for high-reliability aerospace and defense systems.
Technical Context
The MXLDA3KP20AE3 operates as a unidirectional avalanche diode-based TVS array optimized for fast transient suppression in DC power rails. Its <100 ps response time enables effective ESD protection, while its 10/1000 μs waveform-rated 3000 W peak pulse power handles high-energy surges from lightning-induced coupling or relay coil flyback.
Designed for surface-mount vertical mounting, it features a void-free UL94V-0 epoxy package with tin-lead or matte-tin plating, polarity defined by dot-marked Pin 1 (cathode), and traceable wafer/assembly lot control meeting high-reliability screening requirements per MIL-PRF-19500.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the clamping voltage of MXLDA3KP20AE3 at its rated peak pulse current?
The MXLDA3KP20AE3 has a maximum clamping voltage (VC) of 32.4 V at 92.6 A peak pulse current (IPP), measured under 10/1000 μs waveform conditions. This value ensures downstream components see no more than 32.4 V during worst-case surge events, maintaining safe operating margins for 24 V or 28 V systems. The MXLDA3KP20AE3 achieves this with sub-100 ps response time and stable performance across -55°C to +150°C.
Is MXLDA3KP20AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP20AE3 is RoHS compliant, as confirmed by the 'e3' suffix in its part number. Per Microsemi's nomenclature (RF01243 Rev B, Page 2), 'e3' denotes annealed matte-tin plating meeting EU Directive 2011/65/EU requirements. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and is suitable for environmentally regulated industrial and aerospace applications.
Does MXLDA3KP20AE3 support MIL-PRF-19500 upscreening and what does that entail?
Yes, MXLDA3KP20AE3 supports optional MIL-PRF-19500 upscreening per Micronote 129, including wafer/assembly lot traceability, 3σ screening on standby current (ID), and conformance inspections. This makes MXLDA3KP20AE3 suitable for high-reliability aerospace and defense applications where component pedigree, burn-in, and parametric stability across temperature and life are mandated.
What is the polarity configuration and pin identification method for MXLDA3KP20AE3?
MXLDA3KP20AE3 is a unidirectional TVS with Pin 1 designated as cathode and Pin 2 as anode. Polarity is identified by a dot marking on the top surface of the package adjacent to Pin 1, per RF01243 Rev B, Page 2. This configuration allows it to protect positive-rail circuits by shunting overvoltage to ground when the cathode-to-anode voltage exceeds 22.2 V.
How does MXLDA3KP20AE3 perform under IEC61000-4-5 secondary lightning testing?
MXLDA3KP20AE3 meets IEC61000-4-5 secondary lightning protection up to Class 4 with 42 Ω source impedance, and Class 3 with 12 Ω and 2 Ω source impedances. Its 3000 W peak pulse power rating and 32.4 V clamping voltage ensure reliable suppression of 4 kV/2 kA waveforms in telecom, industrial, and transportation infrastructure applications without degradation.
