Product details
Overview
MDA3KP7.0A 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 MDA3KP7.0A datasheet, MDA3KP7.0A pinout, MDA3KP7.0A application, or MDA3KP7.0A 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 MDA3KP7.0A employs silicon avalanche diode technology with sub-100 ps response time for unidirectional clamping. Its 3000 W peak pulse power rating is specified at 10/1000 µs waveform, and it delivers 12.0 V clamping at 250 A IPP under standardized surge conditions.
It complies with MIL-PRF-19500 screening options for high-reliability applications and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack requirement. Polarity is defined by odd-numbered pins as cathodes, and marking includes date code and part number with pin 1 indicated by dot.
Key Specifications

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 PPP rating, same VWM and V(BR) range, DO-214AA package | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 3/4 | Select when surge energy is ≤600 W and board space favors SMB footprint |
| SMCJ7.0A | 1500 W PPP rating, same VWM, SMC package with higher thermal mass than MDA3KP7.0A | Cannot meet 3000 W requirements of MIL-PRF-19500-specified designs | Choose for cost-sensitive industrial controls where full 3 kW rating is not mandated |
Compared with SMBJ7.0A and SMCJ7.0A, the MDA3KP7.0A delivers double the peak pulse power of SMCJ7.0A and five times that of SMBJ7.0A-enabling single-device compliance with IEC61000-4-5 Class 4 at 42 Ω, while supporting high-reliability screening and extended temperature operation.

FAQ
What is the clamping voltage of MDA3KP7.0A at its rated peak pulse current?
The MDA3KP7.0A has a maximum clamping voltage (VC) of 12.0 V at 250 A peak pulse current (IPP), measured under standard 10/1000 µs waveform conditions. This value ensures protected circuits remain within safe operating limits during high-energy transients. The MDA3KP7.0A achieves this clamping performance while maintaining low leakage (200 µA at 7.0 V VWM) and wide temperature operation from –55 °C to +150 °C.
Is MDA3KP7.0A RoHS compliant?
Yes, MDA3KP7.0A is RoHS compliant, indicated by the "e3" suffix in its full marking per Microsemi's nomenclature guide. The device uses annealed matte-tin or tin-lead plating and void-free UL94V-0 epoxy packaging. Compliance is verified per EU Directive 2011/65/EU, and the MDA3KP7.0A carries no lead exemptions requiring declaration. All manufacturing lots of MDA3KP7.0A shipped post-2019 meet RoHS requirements.
Can MDA3KP7.0A be used for bidirectional protection?
No, MDA3KP7.0A is unidirectional only. Its part number lacks the "C" suffix required for bidirectional variants (e.g., MDA3KP7.0CA). The device conducts only in reverse bias and must be oriented with cathodes toward the protected line. For bidirectional applications such as AC line or differential data bus protection, MDA3KP7.0CA or equivalent bidirectional TVS arrays must be selected instead of MDA3KP7.0A.
What is the package type and mounting method for MDA3KP7.0A?
MDA3KP7.0A uses a proprietary 3-pin surface-mount package with dimensions approximately 21.03 mm × 6.86 mm × 8.64 mm (L×W×H), conforming to void-free UL94V-0 epoxy construction. It is designed for reflow soldering at 260 °C for 10 seconds. Pin 1 is marked by a dot, and odd-numbered pins serve as cathodes. The package supports automated pick-and-place and is compatible with standard SMT assembly lines.
Does MDA3KP7.0A require derating at elevated temperatures?
Yes, MDA3KP7.0A requires thermal derating above 25 °C ambient. Per Figure 3 in the datasheet, its peak pulse power (PPP) decreases linearly to ~70% at +100 °C and ~50% at +150 °C junction temperature. Designers must apply this derating curve when sizing the device for high-temperature environments such as engine compartments or enclosed power enclosures. The MDA3KP7.0A's –55 °C to +150 °C TJ rating remains valid, but surge capability scales with temperature.
