Product details
Overview
MDA3KP7.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails 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.
For engineers reviewing the MDA3KP7.0AE3 datasheet, MDA3KP7.0AE3 pinout, MDA3KP7.0AE3 application, or MDA3KP7.0AE3 equivalent, this device is selected for secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient mitigation in industrial power supplies and telecom interfaces.
Technical Context
The MDA3KP7.0AE3 employs silicon avalanche diode technology with sub-100 ps response time, enabling effective clamping of fast transients before sensitive downstream circuitry is damaged. Its unidirectional polarity and RoHS-compliant matte-tin plating support automated reflow assembly and long-term reliability in harsh environments.
Rated for 3000 W peak pulse power at 10/1000 µs waveform, it delivers 250 A peak impulse current (IPP) while maintaining 12.0 V clamping voltage - critical for protecting 5 V and 3.3 V logic rails without exceeding safe overvoltage thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 7.78–8.6 V @ 10 mA - ensures reliable avalanche initiation above operating rail |
| VC @ IPP | 12.0 V @ 250 A - limits voltage seen by protected ICs during surge events |
| IPP | 250 A - peak current capability under standardized 10/1000 µs surge waveform |
| ID @ VWM | 200 µA - low leakage preserves efficiency in battery-powered or high-impedance circuits |
| TJ range | –55 °C to +150 °C - supports operation in automotive under-hood and industrial control enclosures |
Pinout & Package
MDA3KP7.0AE3 uses a 3-pin SMC (DO-214AB) surface-mount package with void-free UL94V-0 epoxy body and tin-lead or matte-tin terminations. Pin 1 is cathode, marked by a dot on top of the package; odd-numbered pins are cathodes per TVS element.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts during overvoltage to shunt current to ground |
| Pin 2 | Anode | Common anode node tied to system ground or return path |
| Pin 3 | Cathode | Second cathode terminal for dual-channel configuration or redundancy |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | 600 W rating, 10.5 V clamping at 34.4 A IPP, DO-214AA package | Limited to lower-energy transients; not suitable for IEC61000-4-5 Class 4 | Select when cost sensitivity outweighs surge energy requirement and PCB space is constrained |
| 1.5KE7.0A | 1500 W rating, 12.0 V clamping at 125 A IPP, DO-201 package, axial lead | Through-hole mounting only; lacks surface-mount compatibility and thermal cycling robustness | Choose for legacy through-hole designs where rework tolerance and manual assembly are prioritized |
Compared with SMBJ7.0A and 1.5KE7.0A, the MDA3KP7.0AE3 delivers double the surge energy handling of the SMBJ series and enables automated SMT assembly unlike the axial 1.5KE series - making it optimal for high-density, high-reliability industrial and automotive PCBs requiring Class 4 lightning immunity.

FAQ
What is the clamping voltage of MDA3KP7.0AE3 at its rated peak pulse current?
The MDA3KP7.0AE3 has a maximum clamping voltage (VC) of 12.0 V at 250 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is guaranteed per the datasheet's Electrical Characteristics table and defines the upper voltage limit imposed on protected circuits during surge events. The low clamping level ensures compatibility with 5 V and 3.3 V logic families without overstressing input structures. MDA3KP7.0AE3 maintains this performance across its full operating temperature range.
Is MDA3KP7.0AE3 unidirectional or bidirectional?
MDA3KP7.0AE3 is a unidirectional transient voltage suppressor, indicated by the absence of a "C" suffix in its part number. Its polarity is defined with odd-numbered pins as cathodes, and it conducts only during positive overvoltage excursions relative to its anode. This makes it ideal for DC rail protection where reverse voltage is not expected. MDA3KP7.0AE3 does not conduct during negative transients unless paired with a complementary device or used in a bipolar configuration.
What package type does MDA3KP7.0AE3 use, and what are its key mechanical features?
MDA3KP7.0AE3 uses the SMC (DO-214AB) surface-mount package, measuring 21.03–22.05 mm in length, 6.86–7.87 mm in width, and 8.64–9.65 mm in height. It features a void-free UL94V-0 thermosetting epoxy body, matte-tin or tin-lead terminations compliant with MIL-STD-750 Method 2026, and a polarity dot marking pin 1. The package supports reflow soldering up to 260 °C for 10 seconds and weighs approximately 5 grams. MDA3KP7.0AE3's robust mechanical construction ensures reliability under thermal cycling and vibration stress.
Does MDA3KP7.0AE3 meet IEC61000-4-5 for secondary lightning protection?
Yes, MDA3KP7.0AE3 is rated for secondary lightning protection per IEC61000-4-5 with 42 Ω source impedance across Class 1–4, and with 12 Ω and 2 Ω sources for specified classes. Its 3000 W peak pulse power rating and 250 A IPP enable compliance without external derating at 25 °C. Derating curves in Figure 3 of the datasheet define allowable power reduction above 25 °C ambient. MDA3KP7.0AE3's validated performance eliminates need for additional series impedance or staged protection in many industrial and telecom applications.
What is the standoff voltage and leakage current specification for MDA3KP7.0AE3?
MDA3KP7.0AE3 has a rated reverse standoff voltage (VWM) of 7.0 V - the maximum continuous DC or peak AC voltage it blocks without significant conduction. At this voltage, its maximum standby current (ID) is 200 µA at 25 °C, ensuring minimal power loss in always-on circuits. Leakage remains below 1 mA even at 85 °C per derating data, supporting battery-backed and low-power IoT nodes. These values are measured per standard test conditions and confirmed across production lots.
