Product details
Overview
MADA3KP7.0CA 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 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 peak pulse current, and operates across –55 °C to +150 °C junction temperature. It protects against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) in telecom and industrial power supplies.
For engineers reviewing the MADA3KP7.0CA datasheet, MADA3KP7.0CA pinout, MADA3KP7.0CA application, or MADA3KP7.0CA equivalent, this page delivers verified electrical parameters, bidirectional polarity confirmation, IEC61000-4-5 class compliance mapping, thermal derating guidance, and RoHS-compliant packaging details essential for robust overvoltage design.
Technical Context
The MADA3KP7.0CA implements a silicon avalanche diode structure optimized for sub-5 ns response time under 10/1000 µs surge conditions. Its bidirectional configuration enables symmetrical clamping on AC lines or differential data paths without external polarity management.
It is rated for 3000 W peak pulse power per IEC61000-4-5 with 42 Ω, 12 Ω, and 2 Ω source impedances - supporting Class 1–4 lightning protection depending on impedance and voltage grade. Standby leakage remains ≤200 µA at 7.0 V, ensuring minimal impact on low-power monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous operating voltage before clamping begins; matches 5 V or 3.3 V rail systems with margin. |
| V(BR) min/max | 7.78–8.6 V @ I(BR) = 10 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC @ IPP | 12.0 V @ 250 A - Clamping voltage limits downstream IC stress to safe levels during 10/1000 µs surges. |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy lightning-induced surges without failure. |
| ID @ VWM | ≤200 µA - Low leakage preserves battery life and avoids false triggering in sensing circuits. |
| TJ/TSTG | –55 °C to +150 °C - Supports operation in harsh environments including automotive under-hood and industrial motor drives. |

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 PPP rating; same VWM and bidirectional polarity; smaller SMB package. | Lower energy handling limits use to Class 2–3 IEC61000-4-5 or lower-current ESD/EFT scenarios. | Select when board space is constrained and surge energy does not exceed 600 W. |
| 1.5KE7.0CA | 3000 W PPP but axial-leaded DO-201 package; higher thermal resistance; no surface-mount compatibility. | Requires through-hole assembly; unsuitable for automated SMT production or high-density layouts. | Choose only for legacy through-hole designs where rework or manual assembly is acceptable. |
Compared with SMBJ7.0CA and 1.5KE7.0CA, the MADA3KP7.0CA uniquely combines 3000 W surge capability, SMC surface-mount packaging, and bidirectional symmetry - making it optimal for high-density, high-reliability industrial and telecom PCBs requiring Class 4 lightning immunity.

FAQ
What is the clamping voltage of MADA3KP7.0CA at its rated peak pulse current?
The MADA3KP7.0CA has a maximum clamping voltage (VC) of 12.0 V at 250 A peak pulse current under 10/1000 µs waveform conditions. This value is guaranteed across temperature and ensures downstream components experience limited overvoltage stress during surge events. The MADA3KP7.0CA maintains this clamping performance consistently due to its silicon avalanche structure and low dynamic impedance.
Is MADA3KP7.0CA unidirectional or bidirectional?
MADA3KP7.0CA is a bidirectional transient voltage suppressor, indicated by the "C" suffix in its part number. It provides symmetrical clamping for both positive and negative transients, making it suitable for AC lines, differential buses like RS-485 or CAN, and any application requiring polarity-agnostic protection. The MADA3KP7.0CA's bidirectional behavior eliminates the need for dual unidirectional devices or external polarity management.
Does MADA3KP7.0CA comply with RoHS standards?
Yes, MADA3KP7.0CA is RoHS compliant, as confirmed by the "e3" marking designation in its full part number per Microsemi's nomenclature guide. The device uses annealed matte-tin plating on terminals and a lead-free thermosetting epoxy body meeting UL94V-0. This RoHS compliance ensures environmental safety and regulatory alignment for global electronics manufacturing, including the MADA3KP7.0CA's use in EU-based industrial and telecom equipment.
What IEC61000-4-5 protection classes does MADA3KP7.0CA support?
MADA3KP7.0CA supports IEC61000-4-5 Class 1–4 secondary lightning protection depending on source impedance: Class 1–4 at 42 Ω, Class 1–3 at 12 Ω, and Class 4 at 2 Ω. Its 3000 W rating and 12.0 V clamping enable compliance across these configurations. The MADA3KP7.0CA's performance is validated per test waveforms defined in the standard, making it suitable for telecom central office and enterprise network equipment requiring Class 4 certification.
What is the maximum operating temperature range for MADA3KP7.0CA?
MADA3KP7.0CA operates across a junction temperature range of –55 °C to +150 °C, as specified in its absolute maximum ratings. This wide range supports deployment in extreme environments such as automotive under-hood modules, industrial motor drives, and outdoor telecom cabinets. The MADA3KP7.0CA's thermal stability ensures consistent clamping performance and reliability even under sustained high-temperature bias conditions.
