Product details
Overview
MXDA3KP14CAE3 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 protection. It features a 14 V standoff voltage (VWM), 15.6–17.2 V breakdown range (V(BR)), 23.2 V max clamping voltage at 129.4 A peak pulse current, and operates from −55 °C to +150 °C - deployed in telecom power interfaces and industrial I/O protection circuits.
For engineers reviewing the MXDA3KP14CAE3 datasheet, MXDA3KP14CAE3 pinout, MXDA3KP14CAE3 application, or MXDA3KP14CAE3 equivalent, key selection criteria include bidirectional surge handling per IEC61000-4-5 (42 Ω source), 10/1000 µs waveform compliance, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
This TVS array uses silicon avalanche diode technology with a symmetrical bidirectional structure, enabling suppression of both positive and negative transients without polarity dependence. Its <100 ps response time ensures effective ESD (IEC61000-4-2) and EFT (IEC61000-4-4) mitigation, while its 3000 W peak pulse power rating is validated under 10/1000 µs waveform conditions.
The device is rated for 14 V working standoff (VWM) and clamps to ≤23.2 V at 129.4 A IPP, delivering predictable voltage limiting during surge events. Its thermal derating curve (Figure 3) supports stable operation up to +150 °C junction temperature, with moisture sensitivity level 1 per J-STD-020B - eliminating dry-pack requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package (smaller footprint) | Limited to Class 2/3 IEC61000-4-5; insufficient for 3000 W surge scenarios | Select when space-constrained layouts require lower-power protection with identical VWM |
| SMCJ14CA | 1500 W PPP, same DO-214AB package, 23.2 V VC but lower IPP (91.2 A) | Not qualified for MIL-PRF-19500 screening; lacks upscreening path for high-reliability programs | Choose where cost sensitivity outweighs need for 3000 W rating or military-grade reliability |
Compared with SMBJ14CA and SMCJ14CA, MXDA3KP14CAE3 delivers double the surge power handling of SMCJ14CA and five times that of SMBJ14CA - critical for infrastructure-grade lightning immunity - while retaining DO-214AB compatibility and MIL-PRF-19500 upscreening eligibility.

FAQ
What does the 'C' suffix in MXDA3KP14CAE3 indicate?
The 'C' suffix in MXDA3KP14CAE3 denotes bidirectional polarity - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. This eliminates the need for polarity-aware layout or external diode pairing, making it ideal for AC-coupled or differential signal paths where surge direction is unpredictable. MXDA3KP14CAE3 achieves this via matched back-to-back avalanche junctions within a single DO-214AB package.
Is MXDA3KP14CAE3 compliant with IEC61000-4-5 for secondary lightning protection?
Yes, MXDA3KP14CAE3 is validated for secondary lightning protection per IEC61000-4-5 with 42 Ω source impedance up to Class 4, and with 12 Ω and 2 Ω sources up to Class 3 and Class 2 respectively. Its 3000 W peak pulse power rating and 23.2 V clamping voltage at 129.4 A ensure reliable voltage limiting during standardized surge waveforms - confirmed in Figures 1–3 of the official RF01243 datasheet.
What is the significance of the 'e3' suffix in MXDA3KP14CAE3?
'e3' in MXDA3KP14CAE3 indicates RoHS-compliant matte-tin plating on the terminals, meeting EU Directive 2011/65/EU requirements. This finish ensures solderability per MIL-STD-750 Method 2026, supports lead-free reflow profiles, and eliminates hazardous substances without compromising surge performance or thermal cycling reliability - critical for global electronics manufacturing compliance.
Can MXDA3KP14CAE3 be used in place of unidirectional TVS diodes like MDA3KP14AE3?
No - MXDA3KP14CAE3 is strictly bidirectional and not a drop-in replacement for unidirectional variants such as MDA3KP14AE3. While both share identical VWM (14 V), clamping voltage (23.2 V), and package, their polarity behavior differs fundamentally: MDA3KP14AE3 conducts only in reverse bias, whereas MXDA3KP14CAE3 clamps in both directions. Substitution requires circuit-level validation of signal polarity and grounding topology.
Does MXDA3KP14CAE3 require baking before PCB assembly?
No, MXDA3KP14CAE3 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry-pack packaging or pre-reflow baking. This simplifies manufacturing logistics and reduces risk of popcorning during reflow - confirmed in the "Mechanical and Packaging" section of the RF01243 datasheet.
