Product details
Overview
MDA3KP8.0CA 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 8.0 V reverse standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), 13.6 V maximum clamping voltage at 220.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MDA3KP8.0CA datasheet, MDA3KP8.0CA pinout, MDA3KP8.0CA application, or MDA3KP8.0CA equivalent, this device is selected for secondary lightning protection per IEC61000-4-5 (with 2 Ω, 12 Ω, or 42 Ω source impedance), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient mitigation in power supply and interface lines.
Technical Context
The MDA3KP8.0CA is a surface-mount, bidirectional TVS diode array with void-free thermosetting epoxy packaging rated to UL94V-0. Its sub-5 ns response time enables effective suppression of fast transients including ESD (±15 kV contact), EFT (±2 kV), and lightning-induced surges up to 3000 W under 10/1000 μs waveform.
It complies with MIL-PRF-19500 screening options for high-reliability applications and exhibits Level 1 moisture sensitivity (IPC/JEDEC J-STD-020B), eliminating dry pack requirements. Polarity is defined by odd-numbered pins as cathodes, and marking includes date code and part number with pin 1 indicated by a dot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous DC or peak AC operating voltage before clamping begins |
| V(BR) min/max | 8.89–9.83 V @ 1 mA - Ensures reliable turn-on margin above system operating voltage |
| VC @ IPP | 13.6 V @ 220.6 A - Clamping voltage limits downstream IC stress during 10/1000 μs surge events |
| PPP | 3000 W @ 10/1000 μs - Sustains high-energy transients without failure in industrial environments |
| ID @ VWM | 50 μA max - Low leakage preserves signal integrity and minimizes standby power loss |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | 600 W PPP rating, 13.6 V VC @ 48.8 A IPP, DO-214AA package | Lower energy handling; suitable only for Class 2 or lower IEC61000-4-5 environments | Select MDA3KP8.0CA when 3000 W surge immunity is required; SMBJ8.0CA fits space-constrained PCBs but lacks high-reliability screening. |
| SMCJ8.0CA | 1500 W PPP rating, 13.6 V VC @ 110.3 A IPP, DO-214AB package | Mid-tier energy rating; supports Class 3 at 42 Ω but not Class 4 at 12 Ω | Choose MDA3KP8.0CA for mission-critical Class 4 compliance; SMCJ8.0CA offers cost advantage where 1500 W suffices. |
Compared with SMBJ8.0CA and SMCJ8.0CA, the MDA3KP8.0CA delivers triple the peak pulse power and full MIL-PRF-19500 screening eligibility-making it the only option qualified for aerospace secondary lightning protection at Class 4 with 12 Ω source impedance.

FAQ
What is the clamping voltage of MDA3KP8.0CA at its rated peak pulse current?
The MDA3KP8.0CA has a maximum clamping voltage (VC) of 13.6 V at its rated peak pulse current (IPP) of 220.6 A under 10/1000 μs waveform conditions. This value is guaranteed across the full operating temperature range and ensures downstream components remain within safe voltage limits during surge events. The MDA3KP8.0CA achieves this with sub-5 ns response time and low dynamic impedance.
Is MDA3KP8.0CA RoHS compliant?
Yes, MDA3KP8.0CA is RoHS compliant, indicated by the "e3" suffix in its full marking per RF01243 Rev B. The device uses annealed matte-tin plating on terminals and void-free thermosetting epoxy encapsulation meeting UL94V-0. All manufacturing processes for MDA3KP8.0CA comply with Directive 2011/65/EU and its amendments.
How does MDA3KP8.0CA differ from unidirectional variants like MDA3KP8.0A?
The MDA3KP8.0CA is bidirectional, providing symmetrical clamping for both positive and negative transients on differential or AC-coupled lines, whereas MDA3KP8.0A is unidirectional and only clamps negative excursions relative to its anode. The "C" suffix denotes bidirectional construction, and MDA3KP8.0CA's pinout supports dual-channel protection with shared anode (Pin 2), unlike the single-channel unidirectional version.
Can MDA3KP8.0CA be used for IEC61000-4-5 Class 4 lightning protection?
Yes, MDA3KP8.0CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with 12 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B. Its 3000 W peak pulse power and 220.6 A IPP exceed Class 4 requirements, and its <5 ns response time ensures effective energy diversion before system-level damage occurs.
What is the maximum operating temperature for MDA3KP8.0CA?
The MDA3KP8.0CA has a junction and storage temperature range of –55 °C to +150 °C, verified per maximum ratings table in RF01243 Rev B. It maintains full 3000 W surge capability up to +125 °C ambient (derated per Figure 3), and is qualified for high-temperature downhole and avionics applications where sustained operation above 100 °C is required. The MDA3KP8.0CA's epoxy body and metallization ensure stability across this full range.
