Product details
Overview
MDA3KP6.5A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 6.5 V standoff voltage (VWM), 7.22–7.98 V breakdown voltage (V(BR)), and 11.2 V clamping voltage (VC) at 267.9 A peak pulse current, designed for secondary lightning protection per IEC61000-4-5 in telecom power interfaces.
For engineers reviewing the MDA3KP6.5A datasheet, MDA3KP6.5A pinout, MDA3KP6.5A application, or MDA3KP6.5A equivalent, key selection criteria include standoff voltage matching system DC rail, clamping margin relative to protected IC VDD max, surge current capability under 10/1000 µs waveform, and RoHS-compliant matte-tin termination compatibility with lead-free reflow.
Technical Context
The MDA3KP6.5A operates as a unidirectional avalanche diode array with fast <100 ps response time, rated for 3000 W peak pulse power at 10/1000 µs, and tested per MIL-PRF-19500 high-reliability screening options. It exhibits 500 µA maximum standby current at 6.5 V and 150 °C junction temperature rating.
Its clamping behavior is defined at IPP = 267.9 A with VC = 11.2 V, ensuring suppression of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and induced switching transients while maintaining low leakage (<500 µA) across -55 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous DC or peak AC voltage applied without triggering conduction |
| V(BR) min–max | 7.22–7.98 V @ I(BR) - Ensures reliable turn-on above system nominal rail with 5% tolerance margin |
| VC @ IPP | 11.2 V @ 267.9 A - Clamping voltage during 10/1000 µs surge; must stay below protected IC absolute max rating |
| ID @ VWM | ≤500 µA - Low leakage preserves battery life and avoids false triggers in always-on circuits |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients from lightning-induced surges or inductive load switching |
| TJ/TSTG | -55 to +150 °C - Enables deployment in automotive engine compartments and industrial outdoor enclosures |
| RoHS | e3 marking - Matte-tin plating compliant with JEDEC J-STD-020B Level 1 moisture sensitivity, no dry pack required |
Pinout & Package
MDA3KP6.5A uses a 3-pin surface-mount DO-214AB (SMC) package with void-free UL94V-0 epoxy body, tin-lead or matte-tin terminations, and polarity defined by dot marking indicating Pin 1 (cathode). Odd-numbered pins are cathodes per internal array configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected circuit's positive rail; conducts when transient exceeds V(BR) |
| Pin 2 | Anode | Common anode tied to ground reference; forms single-directional clamp path |
| Pin 3 | Cathode | Second cathode terminal enabling dual-channel layout or parallel surge handling |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse rating | Withstands 10/1000 µs surges up to 267.9 A without degradation, meeting IEC61000-4-5 Class 1–4 requirements |
| Unidirectional construction | Prevents reverse-bias leakage on DC-powered lines while enabling precise clamping on positive transients |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace and defense programs via wafer lot traceability and 3σ ID screening |
| Low clamping ratio (VC/VWM) | 11.2 V / 6.5 V ≈ 1.72 - Tighter than typical TVS devices, reducing overvoltage stress on downstream ICs |
| Moisture sensitivity Level 1 | No baking or dry pack needed before SMT assembly, lowering manufacturing cost and process risk |
Applications
| Telecom Power Input Protection | Industrial PLC Digital I/O Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A | 600 W PPP rating, 10.3 V VC @ 38.9 A, DO-214AA package | Limited to lower-energy transients; insufficient for IEC61000-4-5 Class 3+ with 42 Ω source | Select MDA3KP6.5A when 3000 W surge handling is mandatory; SMBJ6.5A suits cost-sensitive consumer-grade designs. |
| 1.5KE6.8A | 1500 W PPP, 10.5 V VC @ 143 A, axial DO-15 package | Through-hole mounting only; not suitable for high-density SMT layouts or automated assembly | Choose MDA3KP6.5A for surface-mount production and higher surge robustness; 1.5KE6.8A fits legacy through-hole boards. |
Compared with SMBJ6.5A and 1.5KE6.8A, the MDA3KP6.5A delivers triple the peak pulse power in an SMT package with tighter clamping ratio and extended temperature range, making it optimal for mission-critical industrial and telecom infrastructure where surge energy exceeds 1000 W.

FAQ
What is the clamping voltage of MDA3KP6.5A at its rated peak pulse current?
The MDA3KP6.5A has a maximum clamping voltage (VC) of 11.2 V at its rated peak pulse current (IPP) of 267.9 A under 10/1000 µs waveform conditions. This value is measured per standard test methods and ensures predictable overvoltage limiting during surge events. The MDA3KP6.5A maintains this clamping performance across its full operating temperature range of -55 °C to +150 °C.
Is MDA3KP6.5A unidirectional or bidirectional, and how is polarity marked?
The MDA3KP6.5A is a unidirectional TVS device, indicated by the absence of "C" suffix in its part number. Polarity is marked on the package with a dot denoting Pin 1 (cathode), and odd-numbered pins serve as cathodes per the internal array structure. This configuration enables precise clamping on positive transients while blocking reverse conduction.
Does MDA3KP6.5A meet IEC61000-4-5 for secondary lightning protection?
Yes, the MDA3KP6.5A is validated for secondary lightning protection per IEC61000-4-5 across multiple source impedances: Class 1–4 with 42 Ω, Class 1–3 with 12 Ω, and Class 2 with 2 Ω source impedance. Its 3000 W peak pulse rating and 11.2 V clamping voltage ensure compliance when deployed per recommended PCB layout and grounding practices.
What is the standoff voltage (VWM) and why is it critical for MDA3KP6.5A selection?
The MDA3KP6.5A has a rated working standoff voltage (VWM) of 6.5 V, meaning it remains non-conductive up to this DC or peak AC voltage. Selecting a VWM ≥ system operating voltage prevents false triggering while ensuring sufficient margin below V(BR) min (7.22 V). For a 5 V rail, MDA3KP6.5A provides 1.5 V headroom-critical for stability under ripple and tolerance variation.
How does the MDA3KP6.5A compare to standard SMBJ-series TVS diodes in surge handling?
The MDA3KP6.5A delivers 3000 W peak pulse power-five times higher than the 600 W rating of SMBJ6.5A-enabling protection against severe transients like lightning-induced surges. Its 11.2 V clamping voltage at 267.9 A also offers superior voltage limiting versus SMBJ6.5A's 10.3 V at only 38.9 A, making the MDA3KP6.5A suitable for infrastructure-grade applications where energy levels exceed 1000 W.
