Product details
Overview
MXDA3KP9.0CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning and ESD protection. It features a 9.0 V reverse standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), 15.4 V maximum clamping voltage (VC) at 194.8 A peak pulse current (IPP), and operates from –55 °C to +150 °C.
For engineers reviewing the MXDA3KP9.0CAE3 datasheet, MXDA3KP9.0CAE3 pinout, MXDA3KP9.0CAE3 application, or MXDA3KP9.0CAE3 equivalent, this device serves as a RoHS-compliant, MIL-PRF-19500 upscreenable TVS for IEC61000-4-2/4-4/4-5-compliant surge protection in telecom interfaces, industrial power supplies, and automotive control modules.
Technical Context
The MXDA3KP9.0CAE3 implements a bidirectional avalanche diode structure optimized for sub-5 ns response time and low clamping ratio (VC/V(BR) ≈ 1.45). Its 10/1000 μs waveform rating of 3000 W enables robust suppression of induced RF transients and switching surges in DC power rails and signal lines.
It complies with IEC61000-4-5 Class 1–4 secondary lightning testing under 2 Ω, 12 Ω, and 42 Ω source impedances, and supports moisture sensitivity Level 1 per J-STD-020B-no dry pack required. Polarity is defined by odd-numbered pins as cathodes.

FAQ
What does the 'C' in MXDA3KP9.0CAE3 indicate?
The 'C' suffix in MXDA3KP9.0CAE3 denotes bidirectional polarity-meaning the device provides symmetrical clamping for both positive and negative transients. This is essential for protecting AC-coupled signals, differential buses like RS-485, or floating grounds where polarity reversal cannot be assumed. Unidirectional variants (e.g., MXDA3KP9.0AE3) are cathode-anode only.
Is MXDA3KP9.0CAE3 compliant with IEC61000-4-5 Class 4 testing?
Yes, MXDA3KP9.0CAE3 is rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 2 Ω source impedance. Per Microsemi RF01243 Rev B, it supports Class 4 under 2 Ω and Class 1–3 under 12 Ω and 42 Ω source impedances-making it suitable for high-threat industrial and telecom infrastructure applications.
What is the maximum clamping voltage of MXDA3KP9.0CAE3 and at what current?
The maximum clamping voltage (VC) of MXDA3KP9.0CAE3 is 15.4 V, measured at its peak pulse current (IPP) of 194.8 A under 10/1000 μs waveform conditions. This value ensures downstream components see no more than 15.4 V during worst-case surge events, preserving safe operating area margins for 3.3 V, 5 V, and 12 V logic and interface ICs.
Does MXDA3KP9.0CAE3 require baking before PCB assembly?
No, MXDA3KP9.0CAE3 does not require baking prior to reflow soldering. It is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life at ≤30 °C/60% RH and can be processed directly from sealed packaging using standard lead-free reflow profiles up to 260 °C peak solder temperature.
How is polarity identified on the MXDA3KP9.0CAE3 package?
Polarity on MXDA3KP9.0CAE3 is indicated by a dot marking Pin 1 on the top surface of the DO-218AB package. As specified in RF01243 Rev B, odd-numbered pins (Pin 1 and Pin 3) are cathodes, while Pin 2 is the common anode-enabling correct orientation during automated placement and ensuring proper clamping direction in bidirectional configurations.
