Product details
Overview
MADA3KP40CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and aerospace systems. It features a 40 V reverse standoff voltage (VWM), 44.4–49.1 V breakdown voltage (V(BR)), 64.5 V maximum clamping voltage (VC) at 46.4 A peak pulse current, and operates across –55 °C to +150 °C junction temperature. It protects against IEC61000-4-2 ESD, IEC61000-4-4 EFT, and secondary lightning per IEC61000-4-5 with 42 Ω, 12 Ω, or 2 Ω source impedance.
For engineers reviewing the MADA3KP40CAE3 datasheet, MADA3KP40CAE3 pinout, MADA3KP40CAE3 application, or MADA3KP40CAE3 equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, RoHS-compliant e3 termination, MIL-PRF-19500 upscreening eligibility, and compatibility with 40 V DC bus protection in power supply inputs and communication interfaces.
Technical Context
The MADA3KP40CAE3 is a surface-mount, void-free epoxy-packaged TVS array with dual-channel bidirectional configuration. Its clamping response time is under 5 ns, and it delivers 64.5 V clamping voltage at 46.4 A IPP under 10/1000 µs waveform - enabling robust suppression of fast-rising transients without compromising downstream circuit integrity.
It supports secondary lightning protection across Class 1–4 per IEC61000-4-5 depending on source impedance (42 Ω, 12 Ω, or 2 Ω), and meets moisture sensitivity Level 1 per IPC/JEDEC J-STD-020B - eliminating dry pack requirements and simplifying SMT assembly logistics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 40 V - Maximum continuous operating voltage before clamping activation; matches 36 V nominal DC bus with 10% margin. |
| V(BR) min/max | 44.4–49.1 V - Confirmed breakdown range at 1 mA; ensures reliable turn-on above system overvoltage thresholds. |
| VC @ IPP | 64.5 V at 46.4 A - Clamping voltage limits protected IC stress during worst-case 3000 W surge events. |
| PPP | 3000 W @ 10/1000 µs - Peak pulse power rating validated per Figure 1; defines energy-handling capability for lightning-level surges. |
| TJ/TSTG | –55 °C to +150 °C - Extended thermal range enables deployment in engine control units, avionics, and outdoor telecom equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ40CA | 600 W PPP rating (vs. 3000 W); 64.5 V VC same; unidirectional/bidirectional variants available. | Limited to lower-energy transients (e.g., ESD/EFT only); unsuitable for IEC61000-4-5 Class 4 lightning. | Select when space-constrained layouts require SMB package and surge energy ≤600 W. |
| SMCJ40CA | 1500 W PPP rating (vs. 3000 W); identical VWM, VC, and bidirectional polarity; DO-214AB package. | Meets IEC61000-4-5 Class 2–3 but not Class 4 with 42 Ω source; lower thermal mass reduces sustained surge capability. | Choose for cost-sensitive industrial designs where 1500 W surge margin suffices and DO-214AB footprint is preferred. |
Compared with SMBJ40CA and SMCJ40CA, the MADA3KP40CAE3 provides 2× and 2× higher peak pulse power respectively, enabling Class 4 secondary lightning protection with 42 Ω source impedance - critical for mission-critical infrastructure where single-event failure is unacceptable.

FAQ
What is the clamping voltage of MADA3KP40CAE3 at its rated peak pulse current?
The MADA3KP40CAE3 has a maximum clamping voltage (VC) of 64.5 V at 46.4 A peak pulse current (IPP) 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. The clamping performance remains stable across –55 °C to +150 °C operating temperature.
Is MADA3KP40CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, the MADA3KP40CAE3 is qualified for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the Applications section of the RF01243 datasheet. Its 3000 W peak pulse power rating and 64.5 V clamping voltage ensure compliance under the 4 kV test level defined for Class 4, making it appropriate for outdoor telecom and utility metering applications.
Does MADA3KP40CAE3 require dry pack handling due to moisture sensitivity?
No, the MADA3KP40CAE3 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 baking or dry pack requirements. This eliminates reflow process complications and supports standard SMT assembly flow without special humidity-controlled storage.
What does the "C" suffix in MADA3KP40CAE3 indicate?
The "C" suffix in MADA3KP40CAE3 explicitly denotes bidirectional polarity, as defined in the Part Nomenclature section on Page 2 of the RF01243 datasheet. This distinguishes it from unidirectional variants (e.g., MADA3KP40AE3) and confirms symmetrical clamping behavior for AC-coupled or differential signal lines such as RS-485, CAN, or Ethernet PHY interfaces.
Can MADA3KP40CAE3 be used in aerospace applications requiring high-reliability screening?
Yes, the MADA3KP40CAE3 supports optional upscreening per MIL-PRF-19500, including wafer and assembly lot traceability, 3σ standby current screening, and conformance inspections. This makes it suitable for aerospace platforms where component pedigree, radiation tolerance, and long-term reliability validation are mandatory per program specifications.
