Product details
Overview
MADA3KP7.5CAE3 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 7.5 V reverse standoff voltage (VWM), 8.33–9.21 V breakdown voltage (V(BR)), 12.9 V maximum clamping voltage at 100 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP7.5CAE3 datasheet, MADA3KP7.5CAE3 pinout, MADA3KP7.5CAE3 application, or MADA3KP7.5CAE3 equivalent, key selection criteria include bidirectional polarity, IEC61000-4-2/4-4/4-5 compliance, 100 A IPP rating, RoHS-compliant e3 termination, and MIL-PRF-19500 upscreening eligibility.
Technical Context
MADA3KP7.5CAE3 implements a silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transients. Its clamping behavior is defined at 10/1000 µs waveform with 3000 W peak pulse power, and it maintains stable VWM = 7.5 V while suppressing surges up to 100 A IPP.
The device uses void-free thermosetting epoxy packaging rated UL94V-0, with tin-lead or matte-tin plating per MIL-STD-750 Method 2026. Polarity is defined by odd-numbered pins as cathodes, and moisture sensitivity is Level 1 per J-STD-020B - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.5 V - maximum continuous operating voltage before clamping begins |
| V(BR) min–max | 8.33–9.21 V @ 1 mA - ensures reliable avalanche initiation across process variation |
| VC @ IPP | 12.9 V @ 100 A - limits downstream voltage stress during 10/1000 µs surge |
| IPP | 100 A - peak impulse current capability per IEC61000-4-5 Class 1–4 testing |
| PPP | 3000 W @ 10/1000 µs - defines energy-handling capacity for transient suppression |
| TJ range | –55 °C to +150 °C - supports operation in harsh industrial and aerospace environments |
| Polarity | Bidirectional - protects AC lines or differential signals without polarity constraints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package | Lower energy handling - suitable only for ESD/EFT, not secondary lightning | Select when board space is constrained and surge threat level is limited to IEC61000-4-2/4-4 |
| 1.5KE7.5CA | 1500 W PPP, axial-leaded DO-15 package, higher leakage (ID ≤500 µA) | Not surface-mountable; requires through-hole assembly and additional strain relief | Select only for legacy through-hole designs where rework to SMD is impractical |
Compared with SMBJ7.5CA and 1.5KE7.5CA, MADA3KP7.5CAE3 delivers 2× and 2× higher peak pulse power respectively, enabling robust secondary lightning protection in compact SMD form factor with MIL-grade reliability options.

FAQ
What is the clamping voltage of MADA3KP7.5CAE3 at its rated peak pulse current?
MADA3KP7.5CAE3 has a maximum clamping voltage (VC) of 12.9 V at 100 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is guaranteed across temperature and process variation, ensuring consistent overvoltage protection for downstream circuitry. The clamping performance is validated per Figure 2 in the RF01243 datasheet and applies specifically to the MADA3KP7.5CAE3 variant.
Is MADA3KP7.5CAE3 compliant with RoHS and what does the 'e3' suffix indicate?
Yes, MADA3KP7.5CAE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies matte-tin plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity, eliminating dry-pack requirements and supporting standard reflow profiles. This compliance is documented in Rev B of datasheet RF01243.
How does the bidirectional configuration of MADA3KP7.5CAE3 affect its use in DC circuits?
MADA3KP7.5CAE3's bidirectional design allows it to protect both polarities of a DC line - for example, clamping positive surges above +7.5 V and negative surges below –7.5 V relative to ground. This eliminates need for dual unidirectional devices in single-line protection, simplifying layout while maintaining full 3000 W surge capability in either direction. Its symmetry is intrinsic to the device structure, not external circuitry.
Can MADA3KP7.5CAE3 be used for IEC61000-4-5 Class 4 testing with 42 Ω source impedance?
Yes, MADA3KP7.5CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as stated in the Applications/Benefits section of RF01243 Rev B. Its 3000 W PPP rating and 100 A IPP capability meet the 4 kV test level requirement, and its bidirectional nature ensures protection regardless of surge polarity.
What is the standby current specification for MADA3KP7.5CAE3 at its rated standoff voltage?
MADA3KP7.5CAE3 has a maximum standby current (ID) of 100 µA at its rated reverse standoff voltage (VWM) of 7.5 V, measured at 25 °C. This low leakage ensures minimal power loss in always-on systems and avoids false triggering in high-impedance sensing nodes. The value is specified in the Electrical Characteristics table on page 3 of RF01243 Rev B.
