Product details
Overview
MADA3KP40CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in power and signal lines. It features a 40 V standoff voltage (VWM), 44.4–49.1 V breakdown range (V(BR)), 64.5 V maximum clamping voltage at 46.4 A peak pulse current, and operates from −55 °C to +150 °C. It protects against secondary lightning (IEC61000-4-5), ESD (IEC61000-4-2), and EFT (IEC61000-4-4) in telecom and industrial power supplies.
For engineers reviewing the MADA3KP40CA datasheet, MADA3KP40CA pinout, MADA3KP40CA application, or MADA3KP40CA equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, 64.5 V clamping at 46.4 A, RoHS-compliant e3 marking, and MIL-PRF-19500 upscreening eligibility for aerospace-grade reliability validation.
Technical Context
The MADA3KP40CA 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 3000 W peak pulse power per channel at 10/1000 µs waveform with <2 µA standby current at 40 V.
It meets IEC61000-4-5 Class 1–4 secondary lightning protection with 42 Ω source impedance and supports derating above 25 °C per Figure 3. Polarity is defined by odd-numbered pins as cathodes, and moisture sensitivity is Level 1 (no dry pack required per J-STD-020B).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ40CA | 600 W PPP rating, same VWM and bidirectional polarity, but lower VC (64.5 V vs. 69.4 V) and smaller SMC package | Lower surge capacity suits consumer-grade 24 V DC systems; insufficient for telecom lightning-class requirements | Select SMBJ40CA only when 3000 W rating is not mandated and board space is constrained |
| 1.5KE40CA | 3000 W rating, axial-leaded DO-201 package, higher thermal resistance, no MIL-PRF-19500 screening path | Through-hole mounting limits automated assembly; unsuitable for high-vibration aerospace deployments | Choose 1.5KE40CA for cost-sensitive prototyping where surface-mount reliability and upscreening are noncritical |
Compared with SMBJ40CA and 1.5KE40CA, the MADA3KP40CA uniquely combines 3000 W surge capability, surface-mount DO-214AB packaging, MIL-PRF-19500 upscreening eligibility, and sub-5 ns response-making it the only option qualified for high-reliability telecom infrastructure and defense electronics surge protection.

FAQ
What does the 'C' suffix in MADA3KP40CA indicate?
The 'C' suffix in MADA3KP40CA denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients across its terminals. This differs from unidirectional variants like MADA3KP40A, which clamp only in one direction relative to the anode. The bidirectional configuration makes MADA3KP40CA ideal for AC-coupled interfaces and floating power rails where polarity reversal is possible.
Is MADA3KP40CA compliant with RoHS and lead-free assembly processes?
Yes, MADA3KP40CA carries the e3 marking, confirming full RoHS compliance per Directive 2011/65/EU. Its matte-tin plating is compatible with standard Pb-free reflow profiles up to 260 °C for 10 seconds, and its Level 1 moisture sensitivity eliminates the need for pre-bake handling. No lead content is present, and the void-free epoxy body meets UL94V-0 flammability requirements.
What is the maximum clamping voltage of MADA3KP40CA and at what test condition is it specified?
The maximum clamping voltage (VC) of MADA3KP40CA is 64.5 V, measured at 46.4 A peak pulse current (IPP) under the standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and represents the upper limit of voltage seen by protected circuitry during worst-case transient events, ensuring downstream components remain within safe operating limits.
Can MADA3KP40CA be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MADA3KP40CA is rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power rating and 64.5 V clamping voltage enable compliance with the 4 kV test level for Class 4, making it suitable for telecom central office and outdoor cabinet deployments.
Does MADA3KP40CA require PCB layout modifications compared to standard SMC-package TVS diodes?
No, MADA3KP40CA uses the industry-standard DO-214AB (SMC) package with identical footprint and pad layout to other SMC devices such as SMBJ and 1.5KE series. The mechanical dimensions-including 21.03–22.05 mm length (A), 6.86–7.87 mm width (B), and 8.64–9.65 mm height (C)-match JEDEC MS-013 specifications, allowing drop-in replacement without PCB redesign.
