Product details
Overview
MXLDA3KP9.0CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning and ESD protection. It features a 9.0 V reverse standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), 15.4 V maximum clamping voltage (VC) at 194.8 A peak pulse current, and operates from –55 °C to +150 °C - used in telecom power interfaces and industrial I/O protection.
For engineers reviewing the MXLDA3KP9.0CAE3 datasheet, MXLDA3KP9.0CAE3 pinout, MXLDA3KP9.0CAE3 application, or MXLDA3KP9.0CAE3 equivalent, key selection criteria include bidirectional polarity, 10/1000 µs surge rating, IEC61000-4-2/4-4/4-5 compliance, RoHS-compliant e3 plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXLDA3KP9.0CAE3 is a monolithic TVS array with symmetrical bidirectional avalanche structure, enabling clamping of both positive and negative transients without external polarity management. Its <100 ps response time and 3000 W peak pulse power rating support robust protection against fast-rising ESD events and slower 10/1000 µs lightning surges.
It complies with IEC61000-4-5 Class 1–4 (42 Ω, 12 Ω, and 2 Ω source impedances), IEC61000-4-2 (±15 kV air, ±8 kV contact), and IEC61000-4-4 (40 A, 5/50 ns). Standby leakage is ≤10 µA at 9.0 V, and it uses void-free UL94V-0 epoxy packaging with tin-lead or matte-tin plating per MIL-STD-750.
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 |
|---|---|---|---|
| SMBJ9.0CA | 600 W PPP rating, 10.0–11.1 V V(BR), same VWM and polarity - lower surge capacity. | Targeted at consumer-grade or low-energy I/O; insufficient for IEC61000-4-5 Class 4. | Select when cost and board space constrain design, and surge threat level is limited to ESD/EFT only. |
| SMCJ9.0CA | 1500 W PPP, same VWM/V(BR)/VC, but smaller SMC package - 50% lower peak current (139 A vs. 194.8 A). | Suitable for mid-tier industrial equipment where Class 3 lightning compliance suffices. | Choose when footprint reduction is prioritized and full 3000 W capability is not required. |

This distinguishes it from unidirectional variants like MXLDA3KP9.0AE3 and makes MXLDA3KP9.0CAE3 ideal for AC-coupled or differential signal lines such as RS-485 or CAN bus interfaces.
Is MXLDA3KP9.0CAE3 compliant with IEC61000-4-5 Class 4?
Yes, MXLDA3KP9.0CAE3 meets IEC61000-4-5 Class 4 requirements when tested with a 2 Ω source impedance, supporting up to 194.8 A peak pulse current at 15.4 V clamping. Its 3000 W rating and specified performance under 10/1000 µs waveform make MXLDA3KP9.0CAE3 suitable for central office telecom and railway signaling applications demanding highest-level secondary lightning immunity.
What is the maximum clamping voltage of MXLDA3KP9.0CAE3 and at what current is it measured?
The maximum clamping voltage (VC) of MXLDA3KP9.0CAE3 is 15.4 V, measured at its rated peak pulse current (IPP) of 194.8 A under 10/1000 µs waveform conditions. This value is guaranteed across temperature and ensures downstream circuitry remains below safe voltage thresholds during worst-case surge events - a critical parameter verified per Figure 2 in the official datasheet.
Does MXLDA3KP9.0CAE3 require moisture-sensitive handling or dry packing?
No, MXLDA3KP9.0CAE3 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it does not absorb sufficient moisture during ambient storage to require dry pack or baking prior to reflow soldering. This simplifies manufacturing logistics and reduces process risk compared to higher-level MSL devices - a confirmed specification in the "Mechanical and Packaging" section of the RF01243 datasheet.
Can MXLDA3KP9.0CAE3 be used in automotive under-hood applications?
Yes, MXLDA3KP9.0CAE3 is rated for junction temperatures from –55 °C to +150 °C and is qualified for high-reliability environments.
