Product details
Overview
MXLDA3KP22CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in DO-214AB (SMC) package, designed for high-reliability surge protection of DC power rails and signal lines. It features 22 V standoff voltage (VWM), 24.4–26.9 V breakdown voltage (V(BR)), 35.5 V maximum clamping voltage at 84.4 A peak pulse current, and operates from −55 °C to +150 °C.
For engineers reviewing the MXLDA3KP22CAE3 datasheet, MXLDA3KP22CAE3 pinout, MXLDA3KP22CAE3 application, or MXLDA3KP22CAE3 equivalent, key selection criteria include bidirectional clamping behavior, IEC 61000-4-2/4-4/4-5 compliance, 10/1000 µs surge rating, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXLDA3KP22CAE3 implements a symmetrical avalanche diode structure enabling equal clamping in both polarities, with sub-5 ns response time and <100 ps turn-on delay. Its 3000 W peak pulse power rating is validated per 10/1000 µs waveform, and it maintains stable performance across −55 °C to +150 °C junction temperature range.
Designed for secondary lightning protection per IEC 61000-4-5 with 2 Ω, 12 Ω, and 42 Ω source impedances, the device supports Class 1–4 testing under 42 Ω, Class 1–3 under 12 Ω, and Class 2–4 under 2 Ω configurations - all confirmed for the MDA3KP22CA variant group.
Key Specifications

| Package | DO-214AB (SMC) - Surface-mount thermoset epoxy case, UL94V-0 rated, 5 g mass, pin 1 marked by dot |
Pinout & Package
MXLDA3KP22CAE3 uses a 2-terminal DO-214AB (SMC) package with cathode-anode symmetry due to bidirectional construction. Pin 1 (cathode) and Pin 2 (anode) are interchangeable for polarity-agnostic placement; marking dot identifies Pin 1. Terminals feature annealed matte-tin plating per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional) | Marked by dot; functions as cathode in positive transients and anode in negative transients |
| Pin 2 | Anode (Bidirectional) | Unmarked terminal; functions as anode in positive transients and cathode in negative transients |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating DC lines without polarity constraints |
| IEC 61000-4-5 Class 1–4 compliance | Validated for secondary lightning surge immunity with 2 Ω, 12 Ω, and 42 Ω source impedances |
| MIL-PRF-19500 upscreening option | Supports high-reliability screening including lot traceability, 3σ ID screening, and surge testing |
| RoHS-compliant matte-tin plating | e3 suffix confirms lead-free termination compatible with Pb-free reflow profiles up to 260 °C |
| Moisture sensitivity Level 1 | No dry pack required per J-STD-020B - simplifies handling and eliminates bake-out prior to assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package | Lower surge capacity; suitable only for non-lightning environments like ESD/EFT-only zones | Select when system-level surge energy is limited to ≤600 W and board space requires smaller SMB footprint |
| 1.5KE22CA | 1500 W PPP, axial-leaded DO-15 package, higher thermal resistance | Not surface-mountable; unsuitable for automated assembly or high-density layouts | Choose only for legacy through-hole designs where rework tolerance outweighs surge margin requirements |
Compared with SMBJ22CA and 1.5KE22CA, MXLDA3KP22CAE3 delivers double the surge energy handling of the former and twice the power density of the latter, while maintaining full SMT compatibility and MIL-PRF-19500 upscreening readiness - critical for aerospace, defense, and infrastructure deployments.

FAQ
What does the 'C' in MXLDA3KP22CAE3 indicate?
The 'C' suffix in MXLDA3KP22CAE3 denotes bidirectional polarity - meaning the device clamps symmetrically for both positive and negative transients. This enables single-component protection of AC signals or floating DC buses without external polarity considerations. The MXLDA3KP22CAE3 achieves this via matched avalanche diodes in anti-parallel configuration, verified in the RF01243 datasheet's Part Nomenclature section.
Is MXLDA3KP22CAE3 RoHS compliant?
Yes, MXLDA3KP22CAE3 is RoHS compliant, as confirmed by the 'e3' suffix in its full part number. This indicates annealed matte-tin plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity, with no dry pack required. The device supports Pb-free reflow profiles up to 260 °C for 10 seconds, per Microsemi's RF01243 Rev B specification.
What is the clamping voltage of MXLDA3KP22CAE3 at its rated peak pulse current?
The MXLDA3KP22CAE3 has a maximum clamping voltage (VC) of 35.5 V at its rated peak pulse current (IPP) of 84.4 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the RF01243 datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can MXLDA3KP22CAE3 be used for IEC 61000-4-5 Class 4 lightning protection?
Yes, MXLDA3KP22CAE3 is validated for IEC 61000-4-5 Class 4 secondary lightning protection when tested with 42 Ω source impedance, as explicitly stated in the Applications/Benefits section of RF01243 Rev B. Its 3000 W PPP rating and 35.5 V clamping ensure compliance without derating in standard test configurations.
Does MXLDA3KP22CAE3 require upscreening for high-reliability programs?
No, MXLDA3KP22CAE3 does not require upscreening to meet baseline specifications - it is manufactured with wafer and assembly lot traceability and 3σ screening on standby current (ID) as standard. However, optional MIL-PRF-19500 upscreening (e.g., extended burn-in, hermeticity, radiation testing) is available upon request per Micronote 129, making MXLDA3KP22CAE3 suitable for aerospace and defense deployments.
