Product details
Overview
MXLDA3KP24CAE3 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 24 V standoff voltage (VWM), 26.7–29.5 V breakdown range (V(BR)), 38.9 V max clamping voltage at 77.2 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 MXLDA3KP24CAE3 datasheet, MXLDA3KP24CAE3 pinout, MXLDA3KP24CAE3 application, or MXLDA3KP24CAE3 equivalent, key selection criteria include bidirectional polarity, 10/1000 µs surge rating, RoHS-compliant matte-tin plating, MIL-PRF-19500 upscreening eligibility, and IEC61000-4-2/4-4/4-5 compliance for system-level transient immunity.
Technical Context
The MXLDA3KP24CAE3 implements a symmetrical silicon avalanche diode structure enabling bidirectional clamping without external polarity constraints. Its sub-5 ns response time and <100 ps turn-on latency ensure effective suppression of ESD events per IEC61000-4-2 and fast-rising inductive transients.
It delivers 3000 W peak pulse power at 10/1000 µs waveform with full derating above 25 °C per Figure 3, and supports secondary lightning protection across Class 1–4 per IEC61000-4-5 under 2 Ω, 12 Ω, and 42 Ω source impedances - validated by factory surge testing on every lot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - maximum continuous DC or RMS operating voltage before clamping initiates |
| V(BR) min/max | 26.7–29.5 V @ 1 mA - guaranteed avalanche onset window defining minimum protection threshold |
| VC @ IPP | 38.9 V @ 77.2 A - clamped voltage during worst-case 10/1000 µs surge, limiting downstream stress |
| IPP | 77.2 A - peak surge current supported at rated clamping voltage, derived from 3000 W / VC |
| ID @ VWM | 2 µA - ultra-low leakage ensuring minimal power loss and signal integrity in standby |
| TJ/TSTG | −55 °C to +150 °C - extended thermal range supporting under-hood, outdoor, and industrial enclosure use |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline with 21.03 × 22.05 mm body and defined pin 1 dot marking |
Pinout & Package
MXLDA3KP24CAE3 uses a 2-terminal DO-214AB (SMC) package with cathode-anode symmetry due to bidirectional construction. Pin 1 is marked by a dot on the top surface; terminals are non-polarized and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (Terminals 1 & 2) | Bidirectional avalanche junction | Either terminal serves as anode or cathode depending on instantaneous polarity - enables symmetric clamping without orientation constraints |
Key Features

|---|---|
| Bidirectional clamping | Eliminates need for polarity-aware placement or dual-device solutions in AC-coupled or floating lines |
| 3000 W 10/1000 µs rating | Supports robust protection against severe lightning-induced surges in telecom and industrial power rails |
| MIL-PRF-19500 upscreening option | Enables qualification for aerospace, defense, and high-integrity systems requiring wafer/lot traceability and 3σ ID screening |
| Moisture sensitivity Level 1 | Permits standard SMT reflow without dry-pack preconditioning or floor-life management overhead |
| RoHS-compliant matte-tin plating | Ensures reliable solderability per MIL-STD-750 Method 2026 and eliminates lead-based process dependencies |
Applications
| Telecom Line Interface Protection | Industrial PLC Analog I/O Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | 600 W rating, SMB package, 38.9 V clamping at 17.3 A IPP | Lower surge capacity; suitable only for light-duty ESD/EFT, not secondary lightning | Select when board space is constrained and surge threat level is Class 2 or lower per IEC61000-4-5 |
| 1.5KE24CA | Through-hole DO-201 package, 1500 W rating, same 24 V VWM and bidirectional polarity | Requires through-hole assembly; lacks MIL-PRF-19500 upscreening path and SMT compatibility | Choose for legacy designs where rework to SMT is impractical but higher surge margin than SMBJ is required |
Compared with SMBJ24CA and 1.5KE24CA, MXLDA3KP24CAE3 delivers 2× and 2× higher peak pulse power respectively, supports RoHS-compliant SMT assembly with Level 1 moisture handling, and offers optional high-reliability screening - making it the preferred choice for new industrial and telecom designs demanding Class 3–4 IEC61000-4-5 compliance.

FAQ
What is the clamping voltage of MXLDA3KP24CAE3 at its rated peak pulse current?
The MXLDA3KP24CAE3 has a maximum clamping voltage (VC) of 38.9 V at its rated peak pulse current (IPP) of 77.2 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is MXLDA3KP24CAE3 compatible with lead-free reflow processes?
Yes, MXLDA3KP24CAE3 features annealed matte-tin plating compliant with MIL-STD-750 Method 2026 and supports standard Pb-free reflow profiles up to 260 °C for 10 seconds. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, eliminating the need for dry-packaging or baking prior to assembly.
Does MXLDA3KP24CAE3 meet IEC61000-4-5 for secondary lightning protection?
Yes, MXLDA3KP24CAE3 is validated for secondary lightning protection per IEC61000-4-5 across Class 1–4 under 2 Ω, 12 Ω, and 42 Ω source impedances. Its 3000 W rating and sub-5 ns response enable compliance in telecom and industrial applications where coupling paths generate high-energy transients.
What does the "C" suffix in MXLDA3KP24CAE3 indicate?
The "C" in MXLDA3KP24CAE3 denotes bidirectional polarity - meaning the device provides symmetrical clamping for both positive and negative transients without requiring orientation-specific placement. This differs from unidirectional variants (e.g., MXLDA3KP24AE3), which require correct anode/cathode alignment relative to ground.
Can MXLDA3KP24CAE3 be used in automotive applications?
Yes, MXLDA3KP24CAE3 is suitable for automotive body control modules and infotainment power inputs, particularly where protection against load-dump transients (ISO 7637-2) and ESD (ISO 10605) is required. Its −55 °C to +150 °C operating range and optional MIL-PRF-19500 screening support under-hood and chassis-mounted deployment.
