Product details
Overview
MDA3KP8.0CAE3 from Microsemi is a bidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. It features 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 MDA3KP8.0CAE3 datasheet, MDA3KP8.0CAE3 pinout, MDA3KP8.0CAE3 application, or MDA3KP8.0CAE3 equivalent, key selection criteria include IEC 61000-4-5 Class 1–4 compliance with 2/12/42 Ω source impedance, bidirectional polarity, RoHS-compliant matte-tin plating, and UL94V-0 void-free epoxy packaging suitable for automated SMT assembly.
Technical Context
The MDA3KP8.0CAE3 implements a symmetrical silicon avalanche diode structure enabling equal clamping in both polarities, critical for AC-coupled signal lines and ungrounded bus protection. Its <5 ns response time and sub-100 ps transition from zero volts to V(BR) min ensure effective suppression of ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and induced RF transients.
Rated for 3000 W peak pulse power at 10/1000 μs waveform, it delivers 220.6 A IPP with 13.6 V VC while maintaining ≤50 μA standby current at 8.0 V VWM - supporting low-leakage system-level protection without compromising signal integrity or bias stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - maximum continuous operating voltage before clamping initiates; matches 5 V or 3.3 V rail systems with margin |
| V(BR) min–max | 8.89–9.83 V @ 1 mA - defines precise avalanche onset threshold for predictable turn-on behavior |
| VC @ IPP | 13.6 V @ 220.6 A - clamping voltage under full 3000 W surge; limits protected circuit stress to safe levels |
| IPP | 220.6 A - peak impulse current capability at 10/1000 μs; supports IEC 61000-4-5 Level 4 with 42 Ω source |
| ID @ VWM | ≤50 μA - ultra-low leakage ensures minimal power loss and no interference with high-impedance sensing nodes |
| TJ range | –55 °C to +150 °C - enables deployment in harsh environments including motor drives and outdoor telecom equipment |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline with 21.03 × 7.87 mm footprint and 5 g mass |
Pinout & Package
MDA3KP8.0CAE3 uses a 2-terminal DO-214AB (SMC) package with cathode marked by a dot on the top surface. Terminals are tin-lead or matte-tin plated per MIL-STD-750 Method 2026 and rated for 260 °C soldering at 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input/Line side terminal | Connected to protected line; forms symmetrical clamp path with cathode during positive or negative transients |
| Cathode (Pin 2) | Reference/Ground side terminal | Marked by dot; serves as common reference point for bidirectional clamping; must connect to low-impedance ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC signals, differential buses (e.g., RS-485), and floating power rails without polarity concerns |
| 3000 W peak pulse rating | Withstands 10/1000 μs surges up to 220.6 A - exceeds IEC 61000-4-5 Class 4 requirements with 42 Ω source impedance |
| RoHS-compliant matte-tin plating | Ensures reliable solder wetting and intermetallic formation in lead-free reflow processes without whisker risk |
| UL94V-0 void-free epoxy body | Provides flame resistance and mechanical robustness for high-vibration or high-humidity industrial enclosures |

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 rating, 13.6 V VC @ 43.7 A IPP - lower energy handling than MDA3KP8.0CAE3's 3000 W/220.6 A | Suitable for board-level ESD only; not rated for IEC 61000-4-5 Class 3/4 lightning testing | Select when space-constrained layouts require SMB package and surge threat level is limited to ESD/EFT. |
| 1.5KE8.0C | Through-hole TO-218 package, same 8.0 V VWM and bidirectional configuration, but 1.5 kW rating and 13.6 V VC @ 111 A IPP | Requires wave soldering or hand assembly; lacks SMT compatibility and MIL-PRF-19500 screening option | Choose for legacy through-hole designs or cost-sensitive applications where automated placement is not required. |
Compared with SMBJ8.0CA and 1.5KE8.0C, the MDA3KP8.0CAE3 provides 5× higher peak power handling and SMT-ready DO-214AB packaging with optional high-reliability screening - making it the preferred choice for mission-critical industrial and telecom surge protection where PCB real estate and ruggedness are balanced.

FAQ
What is the clamping voltage of the MDA3KP8.0CAE3 under maximum surge conditions?
The MDA3KP8.0CAE3 exhibits 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 represents the upper limit of voltage seen by downstream circuitry during worst-case transient events - critical for ensuring protected ICs remain within absolute maximum ratings.
Is the MDA3KP8.0CAE3 compatible with lead-free reflow soldering processes?
Yes, the MDA3KP8.0CAE3 features annealed matte-tin plating compliant with MIL-STD-750 Method 2026 and is rated for 260 °C peak solder temperature at 10 s exposure. Its RoHS-compliant e3 marking confirms suitability for standard Pb-free reflow profiles, including JEDEC J-STD-020D Level 1 moisture sensitivity without dry-pack requirement.
How does the bidirectional design of the MDA3KP8.0CAE3 affect its use in DC power line protection?
The bidirectional design of the MDA3KP8.0CAE3 allows it to clamp transients of either polarity relative to ground - essential for protecting ungrounded or floating DC rails, such as those found in isolated DC-DC converters or battery-backed systems. Unlike unidirectional TVS devices, MDA3KP8.0CAE3 requires no external polarity considerations during layout and provides symmetrical protection without adding series diodes or complex grounding schemes.
Does the MDA3KP8.0CAE3 meet IEC 61000-4-5 Class 4 immunity requirements?
Yes, the MDA3KP8.0CAE3 meets IEC 61000-4-5 Class 4 for secondary lightning protection when tested with a 42 Ω source impedance, delivering 3000 W peak pulse power at 10/1000 μs. Its 220.6 A IPP and 13.6 V VC ensure compliance with the 4 kV open-circuit voltage test level, provided PCB layout maintains low-inductance grounding and proper trace routing per IEC 61000-4-5 implementation guidelines.
What is the significance of the 'C' suffix in MDA3KP8.0CAE3?
The 'C' suffix in MDA3KP8.0CAE3 explicitly denotes bidirectional polarity - distinguishing it from unidirectional variants like MDA3KP8.0AE3. This indicates symmetrical avalanche characteristics across both terminals, enabling clamping of positive and negative transients without polarity-dependent installation. The designation is defined in Microsemi's part nomenclature guide (RF01243 Rev B, Page 2) and is mandatory for correct identification of bidirectional TVS function.
