Product details
Overview
MXDA3KP8.0CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and aerospace systems. It features a 8.0 V reverse standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), 13.6 V maximum clamping voltage (VC) at 220.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXDA3KP8.0CA datasheet, MXDA3KP8.0CA pinout, MXDA3KP8.0CA application, or MXDA3KP8.0CA equivalent, key selection criteria include IEC61000-4-5 secondary lightning compliance (Class 1–4 with 2–42 Ω source impedance), 100 ps response time, RoHS-compliant e3 matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXDA3KP8.0CA implements a silicon avalanche diode structure optimized for fast transient suppression with sub-100 ps response. Its bidirectional configuration enables symmetrical clamping for AC-coupled lines and differential signal paths without polarity constraints.
It delivers 3000 W peak pulse power at 10/1000 µs waveform, supports 220.6 A IPP under standard test conditions, and maintains <5 ns clamping delay-critical for protecting sensitive analog front-ends and high-speed digital interfaces against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and induced RF transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous operating voltage before clamping begins; matches 5 V or 3.3 V rail systems with margin. |
| V(BR) min/max | 8.89–9.83 V - Confirmed avalanche onset range at 1 mA; ensures predictable turn-on without premature conduction. |
| VC @ IPP | 13.6 V - Clamping voltage at 220.6 A peak pulse; limits downstream voltage stress during lightning surges. |
| IPP | 220.6 A - Peak impulse current capability at 10/1000 µs; validates robustness against IEC61000-4-5 Class 4 events. |
| TJ range | –55 °C to +150 °C - Extended thermal envelope enabling use in engine control units and avionics enclosures. |
| Response time | <5 ns - Time from 0 V to V(BR) min; preserves signal integrity in high-speed data lines. |
| RoHS | e3 matte-tin plating - Compliant with lead-free soldering standards and IPC/JEDEC J-STD-020B Level 1 moisture sensitivity. |
Pinout & Package
MXDA3KP8.0CA uses a 3-pin TO-220AB-style vertical surface-mount package with void-free UL94V-0 epoxy body and defined Pin 1 (cathode) 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 clamping terminal for first TVS element; connects to protected line requiring bidirectional surge shunting. |
| Pin 2 | Anode (Common) | Shared anode node for both internal TVS elements; ties to ground or reference plane for symmetrical clamping. |
| Pin 3 | Cathode (Channel 2) | Second clamping terminal; enables differential or dual-rail protection when paired with Pin 1 and Pin 2. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC signals, RS-485 buses, and Ethernet PHYs without external polarity management. |
| 3000 W peak pulse rating | Sustains full-rated surge energy at 10/1000 µs waveform-meets IEC61000-4-5 Class 4 with 2 Ω source impedance. |
| MIL-PRF-19500 screening option | Supports high-reliability qualification including lot traceability, 3σ ID screening, and surge testing per military-grade requirements. |
| Sub-5 ns clamping delay | Minimizes overvoltage exposure time for FPGA I/O banks, ADC inputs, and microcontroller GPIOs during fast transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0CA | 600 W PPP rating, SMA package, 13.6 V VC @ 37.3 A IPP - lower energy handling and smaller thermal mass. | Best suited for low-power consumer ports; insufficient for IEC61000-4-5 Class 4 with 2 Ω source. | Select MXDA3KP8.0CA when full 3000 W surge immunity and MIL-PRF-19500 screening are required. |
| SMCJ8.0CA | 1500 W PPP rating, SMC package, 13.6 V VC @ 110.3 A IPP - half the peak power and reduced thermal endurance. | Valid for IEC61000-4-5 Class 2/3 but not Class 4; lacks upscreening path for aerospace use. | Choose MXDA3KP8.0CA for mission-critical systems needing validated 220.6 A surge current and extended temperature operation. |
Compared with SMAJ8.0CA and SMCJ8.0CA, the MXDA3KP8.0CA provides double the peak pulse power and full Class 4 lightning compliance with 2 Ω source impedance-enabling single-device protection where space-constrained alternatives require derating or cascaded solutions.

FAQ
What is the clamping voltage of MXDA3KP8.0CA at its rated peak pulse current?
The MXDA3KP8.0CA has a maximum clamping voltage (VC) of 13.6 V at its rated peak pulse current (IPP) of 220.6 A under 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is MXDA3KP8.0CA suitable for IEC61000-4-5 Class 4 lightning surge testing?
Yes, MXDA3KP8.0CA is validated for IEC61000-4-5 Class 4 secondary lightning protection with 2 Ω source impedance. Its 3000 W peak pulse power rating and 220.6 A IPP directly meet the 4 kV/2 Ω test requirement, and its bidirectional configuration ensures symmetrical clamping for balanced line protection.
Does MXDA3KP8.0CA support MIL-PRF-19500 high-reliability screening?
Yes, MXDA3KP8.0CA offers optional upscreening per MIL-PRF-19500, including wafer and assembly lot traceability, 3σ screening on standby current (ID), and full surge testing. This makes MXDA3KP8.0CA appropriate for aerospace, defense, and other high-integrity applications requiring documented reliability assurance.
What is the polarity configuration of MXDA3KP8.0CA and how does it affect PCB layout?
MXDA3KP8.0CA is a bidirectional TVS array with odd-numbered pins (1 and 3) serving as cathodes and Pin 2 as the common anode. This allows differential protection across two lines referenced to ground. The dot marking on top identifies Pin 1, and layout must maintain symmetric trace lengths to preserve balanced clamping performance.
How does the thermal performance of MXDA3KP8.0CA compare to smaller-package TVS devices?
MXDA3KP8.0CA's TO-220AB vertical mount package provides significantly higher thermal mass and lower junction-to-ambient resistance than SMA or SMC packages. This enables sustained 3000 W surge dissipation without thermal runaway and supports repeated surge events in high-duty-cycle industrial environments where smaller TVS devices would degrade or fail.
