Product details
Overview
MXLDA3KP20CAE3 from Microsemi is a bidirectional 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 maximum clamping voltage (VC) at 92.6 A peak pulse current (IPP). 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 industrial power interfaces.
For engineers reviewing the MXLDA3KP20CAE3 datasheet, MXLDA3KP20CAE3 pinout, MXLDA3KP20CAE3 application, or MXLDA3KP20CAE3 equivalent, key selection criteria include bidirectional polarity, RoHS-compliant matte-tin plating, 10/1000 µs surge rating, -55°C to +150°C junction temperature range, and compatibility with high-reliability screening per MIL-PRF-19500.
Technical Context
The MXLDA3KP20CAE3 operates as a bidirectional TVS diode array designed for parallel connection across sensitive inputs/outputs. Its clamping action begins at V(BR) min = 22.2 V and limits transient energy to ≤32.4 V at 92.6 A, enabling robust protection of 24 V DC power rails and RS-485/RS-232 signal lines against fast-rising surges.
It features <5 ns response time, 100% surge-tested units, moisture sensitivity level 1 (no dry pack required), and thermal derating per Figure 3 - maintaining full 3000 W capability up to +80°C ambient before linear reduction to 50% at +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 20 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 22.2–24.5 V - breakdown threshold range at 1 mA, defining turn-on precision for predictable clamping onset |
| VC @ IPP | 32.4 V at 92.6 A - clamped voltage during 10/1000 µs surge, directly limiting downstream component stress |
| PPP | 3000 W - peak pulse power handling capacity under standard 10/1000 µs waveform |
| ID @ VWM | 2 µA - ultra-low leakage current ensures minimal standby power loss in always-on systems |
| TJ/TSTG | -55°C to +150°C - wide operating and storage temperature range suitable for under-hood automotive and industrial environments |
| RoHS | e3 - lead-free matte-tin termination compliant with EU RoHS Directive 2011/65/EU |
Pinout & Package
MXLDA3KP20CAE3 uses a 3-pin TO-220AC-style vertical surface-mount package (case outline per RF01243, Page 6) with void-free UL94V-0 epoxy body and tin-lead or matte-tin plating. Pin 1 is cathode (marked by dot); odd-numbered pins are cathodes per internal dual-diode configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of first TVS element | Common anode configuration enables bidirectional clamping between Pins 1–2 and 2–3 |
| Pin 2 | Anode (common center terminal) | Shared anode node; connects to protected line (e.g., signal or power rail) |
| Pin 3 | Cathode of second TVS element | Completes symmetrical bidirectional path; ties to ground or return path |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping on AC-coupled or floating lines without polarity constraints |
| 3000 W 10/1000 µs surge rating | Meets IEC61000-4-5 Class 1–4 requirements with 42 Ω, 12 Ω, and 2 Ω source impedances |
| Moisture sensitivity Level 1 | Eliminates bake-out requirement prior to reflow, reducing assembly cost and risk of delamination |
| MIL-PRF-19500 screening option | Supports high-reliability programs requiring wafer lot traceability and 3σ ID screening |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ20CA | 600 W PPP rating, DO-214AA package, 38.9 V VC @ 17.6 A IPP | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 3/4 compliance | Select when board space is constrained and surge threat level is limited to ESD/EFT only |
| SMCJ20CA | 1500 W PPP rating, DO-214AB package, 32.4 V VC @ 46.3 A IPP | Half the peak power handling; requires parallel placement for 3000 W duty | Choose where existing SMC footprint exists and MIL-PRF-19500 screening is not required |
Compared with SMBJ20CA and SMCJ20CA, MXLDA3KP20CAE3 delivers double the surge power margin of SMCJ20CA and five times that of SMBJ20CA within the same bidirectional 20 V VWM class, while supporting high-reliability screening and direct compliance with IEC61000-4-5 Class 4 at 42 Ω.

FAQ
What is the polarity configuration of the MXLDA3KP20CAE3?
The MXLDA3KP20CAE3 is a bidirectional TVS array, indicated by the "C" suffix in its nomenclature. Internally, it consists of two back-to-back avalanche diodes sharing a common anode (Pin 2), enabling symmetrical clamping for AC signals or floating DC buses without polarity concerns. This structure supports protection of differential lines like RS-485 or ungrounded power rails.
Does the MXLDA3KP20CAE3 meet IEC61000-4-5 Class 4 requirements?
Yes, the MXLDA3KP20CAE3 meets IEC61000-4-5 Class 4 for secondary lightning protection with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B. Its 3000 W peak pulse power rating and 32.4 V clamping voltage at 92.6 A ensure compliance under the 42 Ω test condition, though Class 4 at 12 Ω and 2 Ω requires verification per specific system-level testing.
What is the maximum clamping voltage of the MXLDA3KP20CAE3 at rated surge current?
The MXLDA3KP20CAE3 has a maximum clamping voltage (VC) of 32.4 V at its rated peak pulse current (IPP) of 92.6 A under the standard 10/1000 µs waveform. This value is measured per Figure 2 in RF01243 Rev B and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is the MXLDA3KP20CAE3 suitable for automotive under-hood applications?
Yes, the MXLDA3KP20CAE3 supports junction temperatures from -55°C to +150°C and is qualified for high-reliability screening per MIL-PRF-19500. Its thermal derating curve (Figure 3) maintains full 3000 W capability up to +80°C ambient, making it suitable for under-hood body control modules where ambient temperatures exceed 105°C and transient threats include load dump and ISO 7637-2 pulses.
What does the "e3" suffix indicate in MXLDA3KP20CAE3?
The "e3" suffix in MXLDA3KP20CAE3 indicates RoHS-compliant matte-tin plating on all terminations, per JEDEC J-STD-609A. This replaces traditional tin-lead finishes and ensures compatibility with lead-free reflow processes while maintaining solderability per MIL-STD-750 Method 2026. The "e3" marking is laser-etched or molded into the package body.
