Product details
Overview
MDA3KP6.5CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in power rails and signal lines. It features a 6.5 V standoff voltage (VWM), 7.22–7.98 V breakdown voltage (V(BR)), 11.2 V clamping voltage at 267.9 A peak pulse current, and operates across –55 °C to +150 °C. It is used in industrial power supplies for secondary lightning protection per IEC61000-4-5 with 12 Ω source impedance (Class 1–3).
For engineers reviewing the MDA3KP6.5CA datasheet, MDA3KP6.5CA pinout, MDA3KP6.5CA application, or MDA3KP6.5CA equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, RoHS-compliant e3 marking, 5 g package weight, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MDA3KP6.5CA implements a silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transients. Its clamping behavior is defined by a controlled avalanche breakdown at 7.22–7.98 V, limiting voltage excursions to ≤11.2 V at 267.9 A IPP under 10/1000 µs waveform.
It supports secondary lightning protection per IEC61000-4-5 at multiple source impedances: Class 1–3 with 12 Ω, Class 4 with 2 Ω, and Class 1–4 with 42 Ω - all validated for MDA3KP6.5CA specifically per RF01243 Rev B, Page 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V maximum continuous reverse standoff voltage - sets minimum operating rail margin before conduction |
| V(BR) min–max | 7.22–7.98 V at I(BR) = 10 mA - defines precise avalanche initiation window for predictable clamping onset |
| VC @ IPP | 11.2 V at 267.9 A peak pulse current - ensures protected circuit sees ≤11.2 V during worst-case 10/1000 µs surge |
| PPP | 3000 W peak pulse power @ 10/1000 µs - enables robust handling of lightning-induced surges without degradation |
| ID @ VWM | 500 µA max standby leakage - minimizes quiescent power loss in always-on protection circuits |
| TJ/TSTG | –55 °C to +150 °C junction/storage range - supports operation in harsh industrial and aerospace environments |
| RoHS | e3 marking - confirms lead-free matte-tin plating compliant with IPC/JEDEC J-STD-020B Level 1 moisture sensitivity |
Pinout & Package
MDA3KP6.5CA uses a surface-mount, void-free thermosetting epoxy package (UL94V-0 rated) with tin-lead or matte-tin plating. Pin 1 is marked by a dot on top; odd-numbered pins are cathodes per device polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Primary current sink during positive transients on Channel 1; connects to protected line |
| Pin 2 | Anode (Channel 1) | Reference node for Channel 1; typically tied to ground or common return path |
| Pin 3 | Cathode (Channel 2) | Current sink during positive transients on Channel 2; enables dual-line bidirectional protection |
| Pin 4 | Anode (Channel 2) | Reference for Channel 2; allows independent grounding or shared return with Pin 2 |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5CA | 600 W PPP rating (vs. 3000 W); same VWM/V(BR)/VC but lower IPP (90.2 A) | Not suitable for IEC61000-4-5 Class 3/4; limited to ESD/EFT and low-energy switching transients | Select SMBJ6.5CA only when surge energy is <600 W and board space is constrained. |
| SMCJ6.5CA | 1500 W PPP rating; identical VWM/V(BR)/VC specs but IPP = 133.9 A - half the MDA3KP6.5CA rating | Valid for IEC61000-4-5 Class 1–2 at 42 Ω, but not Class 3/4 at 12 Ω per manufacturer validation | Choose SMCJ6.5CA where cost is prioritized over Class 3/4 compliance and thermal derating margin is acceptable. |
Compared with SMBJ6.5CA and SMCJ6.5CA, the MDA3KP6.5CA delivers 5× and 2× higher peak pulse power respectively, enabling certified secondary lightning protection in Class 3/4 systems - critical for industrial UPS, telecom infrastructure, and grid-tied inverters where surge immunity is mandated.

FAQ
What does the 'C' suffix in MDA3KP6.5CA indicate?
The 'C' suffix in MDA3KP6.5CA explicitly denotes bidirectional polarity per Microsemi's part nomenclature (RF01243 Rev B, Page 2). This means the device conducts and clamps symmetrically for both positive and negative transients across its terminals - essential for protecting AC-coupled or floating DC interfaces without external polarity configuration. The MDA3KP6.5CA achieves this using back-to-back avalanche diode pairs within a single package.
Is MDA3KP6.5CA qualified for IEC61000-4-5 Class 4 testing?
Yes, MDA3KP6.5CA is explicitly validated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 2 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B, Page 1. It is also rated for Class 1–3 at 12 Ω and Class 1–4 at 42 Ω. This multi-class qualification makes MDA3KP6.5CA suitable for telecom central office equipment and industrial PLCs requiring highest-level surge immunity.
What is the maximum clamping voltage of MDA3KP6.5CA and under what test condition?
The maximum clamping voltage (VC) of MDA3KP6.5CA is 11.2 V, measured at a peak impulse current (IPP) of 267.9 A under the standardized 10/1000 µs double-exponential surge waveform (RF01243 Rev B, Page 3). This value represents the upper limit of voltage seen by protected circuitry during worst-case surge events and is guaranteed across the full operating temperature range.
Does MDA3KP6.5CA require dry packing or special handling per moisture sensitivity?
No, MDA3KP6.5CA has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored indefinitely at ambient conditions without dry pack or floor-life restrictions (RF01243 Rev B, Page 2). Its void-free epoxy body and matte-tin plating eliminate moisture ingress risk, simplifying SMT assembly logistics and reducing manufacturing overhead.
Can MDA3KP6.5CA be used for ESD protection per IEC61000-4-2?
Yes, MDA3KP6.5CA is specified for ESD protection per IEC61000-4-2 due to its <5 ns response time (RF01243 Rev B, Page 2). While optimized for high-energy transients, its rapid avalanche turn-on clamps ±8 kV contact discharge events well below damage thresholds of sensitive logic and interface ICs - making it effective for system-level ESD hardening in addition to surge suppression.
