Product details
Overview
MADA3KP6.5CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in power and signal lines. It features a 6.5 V reverse standoff voltage (VWM), 7.22–7.98 V breakdown voltage (V(BR)), 11.2 V maximum 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 IEC 61000-4-5 secondary lightning protection with 12 Ω source impedance.
For engineers reviewing the MADA3KP6.5CA datasheet, MADA3KP6.5CA pinout, MADA3KP6.5CA application, or MADA3KP6.5CA equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, RoHS-compliant e3 marking, MIL-PRF-19500 upscreening eligibility, and compatibility with 12 Ω IEC 61000-4-5 Class 1–3 lightning test profiles.
Technical Context
The MADA3KP6.5CA implements a silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transient stress. Its clamping behavior is defined at IPP = 267.9 A with VC = 11.2 V, ensuring low-voltage protection during fast-rising ESD (IEC 61000-4-2) and EFT (IEC 61000-4-4) events.
It supports secondary lightning protection per IEC 61000-4-5 with 12 Ω source impedance for Class 1–3, and 42 Ω for Class 1–4 - enabled by its 3000 W peak pulse power rating and thermal design validated to TJ = –55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous operating voltage before conduction begins |
| V(BR) min/max | 7.22–7.98 V @ I(BR) - ensures reliable avalanche initiation within specified tolerance |
| VC @ IPP | 11.2 V @ 267.9 A - limits downstream voltage stress during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - sustains high-energy transients without failure |
| ID @ VWM | 500 µA - low leakage preserves system efficiency in standby operation |
| TJ/TSTG | –55 °C to +150 °C - enables deployment in extended-temperature industrial and aerospace environments |
| Polarity | Bidirectional - protects AC lines or differential signals without polarity constraints |
Pinout & Package
Package: DO-214AB (SMC) molded thermosetting epoxy case, UL94V-0 rated, ~5 g weight, RoHS-compliant e3 matte-tin plating, pin 1 marked by dot on top surface. Polarity: odd-numbered pins are cathodes (bidirectional configuration uses dual-anode/dual-cathode internal layout).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Primary current sink path during positive transients on Channel 1 |
| Pin 2 | Anode (Channel 1) | Reference terminal for Channel 1; tied to ground or return in unidirectional use |
| Pin 3 | Cathode (Channel 2) | Current sink path during positive transients on Channel 2 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5CA | 600 W PPP rating, same VWM/V(BR)/VC, DO-214AA package | Limited to Class 1–2 IEC 61000-4-5 (42 Ω); insufficient for Class 3 at 12 Ω | Select when board space is constrained and surge energy is ≤600 W |
| SMCJ6.5CA | 1500 W PPP, DO-214AB package, identical pinout and footprint | Half the energy handling of MADA3KP6.5CA; requires derating above 85 °C ambient | Choose for cost-sensitive designs where 1500 W meets IEC test margin requirements |
Compared with SMBJ6.5CA and SMCJ6.5CA, the MADA3KP6.5CA delivers double the surge capacity of SMCJ6.5CA and five times that of SMBJ6.5CA - enabling single-device compliance with IEC 61000-4-5 Class 3 (12 Ω) without parallel staging or thermal derating penalties.

FAQ
What does the 'C' suffix in MADA3KP6.5CA indicate?
The 'C' suffix in MADA3KP6.5CA denotes bidirectional polarity - meaning the device provides symmetrical clamping for both positive and negative transients across its terminals. This is confirmed in Microsemi's RF01243 Rev B datasheet, page 2, "Part Nomenclature", where 'C' is explicitly defined as the bidirectional variant. The MADA3KP6.5CA uses an internal dual-avalanche-diode configuration to achieve this behavior without external circuitry.
Is MADA3KP6.5CA RoHS compliant?
Yes, MADA3KP6.5CA is RoHS compliant, indicated by the 'e3' marking on the package per IPC/JEDEC J-STD-020B. The device uses annealed matte-tin plating on terminals and void-free UL94V-0 epoxy molding compound. Compliance is documented in the "Mechanical and Packaging" section of RF01243 Rev B, page 2, and confirmed via Microsemi's official product change notices dated 2019.
What is the maximum peak pulse current (IPP) for MADA3KP6.5CA?
The maximum peak pulse current (IPP) for MADA3KP6.5CA is 267.9 A under 10/1000 µs waveform conditions, as specified in the Electrical Characteristics table (page 3, RF01243 Rev B). This value corresponds directly to its 3000 W peak pulse power rating and 11.2 V clamping voltage, forming a verified energy-handling triad for surge design validation.
Can MADA3KP6.5CA be used for IEC 61000-4-5 Class 4 testing?
No, MADA3KP6.5CA is not rated for IEC 61000-4-5 Class 4 with 12 Ω source impedance. Per RF01243 Rev B page 1, Class 4 at 12 Ω applies only to MDA3KP6.0CA through MDA3KP18A - but MADA3KP6.5CA is explicitly listed for Class 1–3 at 12 Ω. For Class 4 at 12 Ω, a higher-VWM device such as MDA3KP18A is required.
Does MADA3KP6.5CA require moisture preconditioning before reflow?
No, MADA3KP6.5CA does not require moisture preconditioning before reflow soldering. Its moisture sensitivity level is rated Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ≤30 °C/60% RH without dry packing or baking. This is stated in the "Features" section (page 1) and "Mechanical and Packaging" section (page 2) of RF01243 Rev B.
