Product details
Overview
MADA3KP7.0CAE3 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 protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT protection per IEC61000-4-4. It features a 7.0 V reverse standoff voltage (VWM), 7.78–8.6 V breakdown voltage (V(BR)), 12.0 V maximum clamping voltage at 250 A IPP, <5 ns response time, and operates from –55 °C to +150 °C.
For engineers reviewing the MADA3KP7.0CAE3 datasheet, MADA3KP7.0CAE3 pinout, MADA3KP7.0CAE3 application, or MADA3KP7.0CAE3 equivalent, this page delivers verified electrical parameters, bidirectional polarity mapping, IEC-compliant surge class coverage, thermal derating behavior, and RoHS-compliant (e3) packaging details essential for industrial power interface, telecom line card, and automotive body control module protection design.
Technical Context
The MADA3KP7.0CAE3 implements a symmetrical silicon avalanche diode structure enabling bidirectional clamping across both polarities without external biasing. Its sub-5 ns response ensures effective suppression of fast-rising ESD transients and switching-induced spikes before downstream ICs are damaged.
It is rated for 3000 W peak pulse power at 10/1000 µs waveform, with clamping performance validated up to 250 A peak impulse current (IPP) and full thermal derating support from –55 °C to +150 °C junction temperature per Figure 3 in RF01243 Rev B.
Key Specifications

Pinout & Package
Package: DO-214AB (SMC), void-free thermosetting epoxy body meeting UL94V-0; dimensions per Page 6 of RF01243 Rev B (A = 21.03–22.05 mm, B = 6.86–7.87 mm, C = 8.64–9.65 mm); weight ≈5 g; polarity defined by dot marking on top indicating Pin 1 (cathode for unidirectional, symmetrical for bidirectional).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | 600 W rating (vs. 3000 W); 10.3 V VC @ 30 A IPP; DO-214AA package (smaller footprint) | Limited to lower-energy ESD/EFT; unsuitable for IEC61000-4-5 Class 3/4 or lightning-induced surges | Select when board space is constrained and surge threat level is ≤1 kV IEC61000-4-5. |
| 1.5KE7.0CA | 1500 W rating; axial-leaded DO-15 package; higher thermal resistance; 12.5 V VC @ 121 A IPP | Requires through-hole assembly; less suitable for automated SMT production and high-density layouts | Choose only for legacy through-hole designs where rework to SMD is not feasible. |
Compared with SMBJ7.0CA and 1.5KE7.0CA, the MADA3KP7.0CAE3 delivers five times higher peak power handling, validated bidirectional Class 4 lightning immunity, and RoHS-compliant SMT compatibility - making it the sole option for new industrial and telecom designs requiring 3 kW surge resilience in compact surface-mount form.

FAQ
What is the clamping voltage of MADA3KP7.0CAE3 at its rated peak pulse current?
The MADA3KP7.0CAE3 has a maximum clamping voltage (VC) of 12.0 V at its rated peak impulse current (IPP) of 250 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in RF01243 Rev B and guarantees that downstream circuitry sees no more than 12.0 V during worst-case surge events, protecting 3.3 V and 5 V logic interfaces effectively.
Is MADA3KP7.0CAE3 suitable for IEC61000-4-5 Class 4 testing with 12 Ω source impedance?
Yes, MADA3KP7.0CAE3 is explicitly validated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 12 Ω source impedance, as confirmed in the "APPLICATIONS / BENEFITS" section of RF01243 Rev B. Its 3000 W rating and 250 A IPP capability meet the 4 kV test requirement for this class without derating.
Does MADA3KP7.0CAE3 require moisture-sensitive handling or dry packing before reflow?
No, MADA3KP7.0CAE3 is rated IPC/JEDEC J-STD-020B Level 1 for moisture sensitivity, meaning it has unlimited floor life and does not require dry packing or baking prior to SMT reflow. This simplifies manufacturing logistics and eliminates yield risk from moisture-related popcorning during soldering.
How is polarity identified on the MADA3KP7.0CAE3 package?
The MADA3KP7.0CAE3 uses a dot marking on the top surface of the DO-214AB package to indicate Pin 1. As a bidirectional device, Pins 1 and 2 are functionally symmetrical - the dot serves only for mechanical orientation and alignment during placement, not for polarity-dependent connection.
What is the maximum operating temperature range for MADA3KP7.0CAE3?
The MADA3KP7.0CAE3 is specified for continuous operation from –55 °C to +150 °C junction temperature, with full electrical performance maintained across this range. Thermal derating curves in Figure 3 of RF01243 Rev B confirm usable pulse power down to 50% of rated 3000 W at +125 °C ambient.
