Product details
Overview
MDA3KP9.0CAE3 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 9.0 V reverse standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), 15.4 V maximum clamping voltage at 194.8 A peak pulse current, and operates from −55 °C to +150 °C. 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 MDA3KP9.0CAE3 datasheet, MDA3KP9.0CAE3 pinout, MDA3KP9.0CAE3 application, or MDA3KP9.0CAE3 equivalent, key selection criteria include bidirectional polarity, 15.4 V clamping at 194.8 A, RoHS-compliant matte-tin plating, MIL-PRF-19500 upscreening eligibility, and compatibility with 10/1000 µs surge waveforms.
Technical Context
The MDA3KP9.0CAE3 is a surface-mount, void-free epoxy-packaged TVS array with bidirectional polarity indicated by the "C" suffix. Its clamping response time is under 5 ns, enabling effective suppression of fast transients including ESD and switching spikes. The device uses silicon avalanche diode technology and is surge-tested per IEC61000-4-5 with 2 Ω, 12 Ω, and 42 Ω source impedances.
It supports secondary lightning protection up to Class 4 with 12 Ω source impedance and Class 2 with 2 Ω source impedance. Standby leakage current is limited to ≤10 µA at 9.0 V, and it meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack requirement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package | Limited to lower-energy surges; unsuitable for IEC61000-4-5 Class 4 with 12 Ω source | Select when board space is constrained and surge energy does not exceed 600 W |
| SMCJ9.0CA | 1500 W PPP rating, same VWM and polarity, DO-214AB package, higher thermal mass than SMBJ but half the power of MDA3KP9.0CAE3 | Supports Class 3 lightning only with 42 Ω source; insufficient for Class 4 at 12 Ω | Choose for cost-sensitive industrial designs where 1500 W clamping suffices and footprint compatibility with DO-214AB is required |

FAQ
What does the "C" in MDA3KP9.0CAE3 indicate?
The "C" suffix in MDA3KP9.0CAE3 denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients. This enables protection of AC-coupled or differential signal paths without requiring external polarity alignment. The MDA3KP9.0CAE3 achieves this using back-to-back avalanche diode configuration within its vertical surface-mount package.
Is MDA3KP9.0CAE3 RoHS compliant?
Yes, MDA3KP9.0CAE3 is RoHS compliant, as confirmed by the "e3" suffix in the part number and documentation in RF01243 Rev B. It features annealed matte-tin plating on terminals and meets lead-free soldering requirements per JEDEC J-STD-020B Level 1, eliminating need for dry pack or pre-bake prior to reflow assembly.
What is the maximum clamping voltage of MDA3KP9.0CAE3 under surge conditions?
The maximum clamping voltage (VC) of MDA3KP9.0CAE3 is 15.4 V at 194.8 A peak pulse current under 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and ensures downstream circuitry remains below destructive voltage thresholds during high-energy transients such as lightning-induced surges.
Can MDA3KP9.0CAE3 be used for IEC61000-4-5 Class 4 lightning protection?
Yes, MDA3KP9.0CAE3 is rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 12 Ω source impedance, as explicitly stated in the Applications/Benefits section of RF01243 Rev B. Its 3000 W peak pulse power and sub-5 ns response enable compliance where lower-power TVS devices fail.
What is the junction temperature range for MDA3KP9.0CAE3?
The junction and storage temperature range for MDA3KP9.0CAE3 is −55 °C to +150 °C, as specified in the Maximum Ratings table on page 2 of RF01243 Rev B. This wide range supports deployment in uncontrolled environments such as outdoor telecom enclosures, engine compartments, and industrial control cabinets without derating at elevated ambient temperatures.
