Product details
Overview
MADA3KP6.5CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD protection. It features a 6.5 V standoff voltage (VWM), 7.22–7.98 V breakdown range (V(BR)), 11.2 V clamping voltage at 267.9 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MADA3KP6.5CAE3 datasheet, MADA3KP6.5CAE3 pinout, MADA3KP6.5CAE3 application, or MADA3KP6.5CAE3 equivalent, key selection criteria include bidirectional polarity, IEC 61000-4-2/4-4/4-5 compliance, 10/1000 µs surge rating, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MADA3KP6.5CAE3 implements a silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transients. Its clamping behavior is characterized at 267.9 A IPP with VC = 11.2 V, ensuring predictable voltage limiting during fast-rising surges such as EFT or induced RF.
Designed for surface-mount assembly on PCBs with IPC/JEDEC J-STD-020B Level 1 moisture sensitivity, it supports reflow soldering up to 260 °C for 10 s and maintains full 3000 W peak pulse power capability at 25 °C with derating above 25 °C per Figure 3.

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 rating (vs. 3000 W); 10.3 V clamping at 32.4 A IPP; DO-214AA package. | Limited to lower-energy threats (e.g., ESD-only); unsuitable for IEC 61000-4-5 Class 3+ or lightning surges. | Select only when peak threat energy is <100 mJ and layout space is constrained. |
| SMCJ6.5CA | 1500 W rating; 11.2 V clamping at 134 A IPP; same DO-214AB package but lower PPP. | Meets IEC 61000-4-5 Class 2 (42 Ω) but not Class 3 (12 Ω); insufficient for high-energy industrial surges. | Choose where cost is prioritized over MIL-grade reliability and full 3000 W headroom. |

FAQ
What is the clamping voltage of MADA3KP6.5CAE3 at its rated peak pulse current?
The MADA3KP6.5CAE3 exhibits 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 defined in the datasheet and ensures downstream circuitry remains within safe voltage limits during surge events. The MADA3KP6.5CAE3 maintains this clamping performance across its full operating temperature range.
Is MADA3KP6.5CAE3 suitable for IEC 61000-4-5 Class 3 lightning surge testing?
Yes, the MADA3KP6.5CAE3 is explicitly rated for IEC 61000-4-5 Class 3 secondary lightning protection with a 12 Ω source impedance, supporting up to 267.9 A peak current. Its 3000 W peak pulse power rating and 11.2 V clamping voltage meet the voltage-limiting and energy-handling requirements of this class. The MADA3KP6.5CAE3 is listed in the official application table on page 1 of RF01243 Rev B for this use case.
Does MADA3KP6.5CAE3 require baking before reflow soldering?
No, the MADA3KP6.5CAE3 has IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1 rating, meaning it may be stored indefinitely at ambient conditions without moisture absorption concerns. No baking or dry packing is required prior to standard reflow soldering at 260 °C for 10 seconds. This simplifies manufacturing flow and reduces process risk compared to higher MSL-rated components.
What does the "C" suffix in MADA3KP6.5CAE3 indicate?
The "C" suffix in MADA3KP6.5CAE3 denotes bidirectional polarity, meaning the device contains two back-to-back avalanche diodes sharing a common cathode (Pin 2). This enables symmetrical clamping for AC signals or differential buses like RS-485 or CAN. In contrast, non-C variants (e.g., MADA3KP6.5AE3) are unidirectional and intended for DC rail protection only. The MADA3KP6.5CAE3's pinout reflects this architecture with Pins 1 and 3 as anodes.
Can MADA3KP6.5CAE3 be used for ESD protection per IEC 61000-4-2?
Yes, the MADA3KP6.5CAE3 is specified for ESD protection per IEC 61000-4-2 due to its <5 ns response time and ability to clamp ±15 kV contact discharges. Its bidirectional structure and low clamping voltage (11.2 V) make it effective on high-speed data lines where fast transients could otherwise disrupt communication. The MADA3KP6.5CAE3 is explicitly cited in the Applications section of RF01243 Rev B for this purpose.
