Product details
Overview
MXDA3KP8.0CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning protection per IEC61000-4-5 with 12 Ω and 2 Ω source impedances, ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient clamping. It features 8.0 V reverse standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), and 13.6 V maximum clamping voltage (VC) at 220.6 A peak pulse current (IPP).
For engineers reviewing the MXDA3KP8.0CAE3 datasheet, MXDA3KP8.0CAE3 pinout, MXDA3KP8.0CAE3 application, or MXDA3KP8.0CAE3 equivalent, key selection criteria include bidirectional polarity, RoHS-compliant matte-tin plating, 10/1000 µs surge rating, -55°C to +150°C operating junction temperature, and compatibility with MIL-PRF-19500 upscreening options.
Technical Context
The MXDA3KP8.0CAE3 implements a symmetrical avalanche diode structure enabling bidirectional clamping across both polarities, with sub-5 ns response time and <100 ps turn-on delay. Its 3000 W peak pulse power rating is validated at 10/1000 µs waveform with ≤0.05% duty factor, and it maintains stable clamping performance under temperature derating per Figure 3.
Designed for high-reliability industrial and aerospace systems, it supports secondary lightning protection classes 1–3 at 12 Ω impedance and class 4 at 2 Ω impedance. Standby current is limited to 50 µA at VWM, and moisture sensitivity is Level 1 per J-STD-020B-no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous working voltage before clamping begins; matches 5–6 V rail systems with safety margin. |
| V(BR) min–max | 8.89–9.83 V - Confirmed avalanche onset range at 1 mA test current; ensures predictable turn-on threshold. |
| VC @ IPP | 13.6 V - Clamping voltage at 220.6 A peak pulse; limits downstream voltage stress during transients. |
| IPP | 220.6 A - Peak impulse current capability at 10/1000 µs; defines maximum energy absorption per event. |
| TJ/TSTG | -55°C to +150°C - Full military-grade thermal operating and storage range; enables deployment in harsh environments. |
| Moisture Sensitivity | Level 1 per J-STD-020B - No baking or dry-pack required prior to reflow; simplifies manufacturing handling. |
| RoHS Compliance | e3 suffix - Matte-tin terminal plating compliant with EU RoHS Directive 2011/65/EU; lead-free assembly compatible. |
Pinout & Package
MXDA3KP8.0CAE3 uses a 3-pin surface-mount plastic package (case outline per Page 6 of RF01243 Rev B), void-free UL94V-0 epoxy body, with odd-numbered pins designated as cathodes. Pin 1 is marked by a dot on top of the package. Terminals are annealed matte-tin plated for solderability per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Primary clamping node for one bidirectional path; connects to protected line (e.g., RS-485 A). |
| Pin 2 | Anode/Cathode Center Tap | Common reference point for symmetrical clamping; ties to system ground or common return. |
| Pin 3 | Cathode of Channel 2 | Clamping node for second bidirectional path; connects to complementary protected line (e.g., RS-485 B). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping on AC-coupled or differential signal lines without polarity constraints. |
| 3000 W peak pulse power | Handles high-energy surges such as IEC61000-4-5 Class 4 events with 2 Ω source impedance. |
| MIL-PRF-19500 upscreening option | Supports high-reliability screening including lot traceability, 3σ ID testing, and conformance inspection. |
| Sub-5 ns response time | Clamps ESD and EFT transients faster than most IC-level protection, preserving signal integrity. |
| Level 1 moisture sensitivity | Eliminates pre-reflow baking steps, reducing process cost and risk of popcorn cracking. |

IC Role / Device Role / Timing Role: Point-of-entry TVS on isolated digital communication lines (e.g., SPI, UART) between MCU and isolated gate drivers. Use Value: Sub-5 ns response prevents false triggering of fault logic; RoHS-compliant e3 plating ensures compatibility with lead-free reflow profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0CA | Lower PPP rating (400 W), smaller SMA package, 13.6 V VC at 32.4 A IPP | Suitable for lower-energy ESD/EFT only; not rated for IEC61000-4-5 Class 4 or secondary lightning | Select MXDA3KP8.0CAE3 when 3000 W surge immunity and MIL-PRF-19500 screening are required. |
| SMCJ8.0CA | Same 3000 W rating but SMC package (larger footprint), 13.6 V VC at 220.6 A IPP, no e3 RoHS marking confirmed | Compatible for PCB space-constrained designs where SMC footprint is acceptable; lacks documented upscreening path | Choose MXDA3KP8.0CAE3 for RoHS compliance assurance and traceable high-reliability screening options. |
Compared with SMAJ8.0CA and SMCJ8.0CA, MXDA3KP8.0CAE3 delivers identical clamping voltage but adds MIL-PRF-19500 upscreening support, Level 1 moisture rating, and explicit IEC61000-4-5 Class 4 validation at 2 Ω impedance-critical for aerospace and industrial safety-critical systems.

FAQ
What is the clamping voltage of MXDA3KP8.0CAE3 at its rated peak pulse current?
The MXDA3KP8.0CAE3 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 measured across the device terminals during surge events and defines the upper voltage limit imposed on protected circuitry. The MXDA3KP8.0CAE3 maintains this clamping performance across its full operating temperature range of -55°C to +150°C, with derating applied above 25°C per Figure 3 in the datasheet.
Is MXDA3KP8.0CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXDA3KP8.0CAE3 is explicitly rated 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. It also supports Class 1–3 at 12 Ω and Class 1–4 at 42 Ω impedance. The MXDA3KP8.0CAE3 achieves this with its 3000 W peak pulse power rating and sub-5 ns response time, making it appropriate for high-energy surge environments such as outdoor telecom equipment and wind turbine control cabinets.
Does MXDA3KP8.0CAE3 require dry packing or baking before reflow soldering?
No, MXDA3KP8.0CAE3 does not require dry packing or baking prior to reflow soldering. Its moisture sensitivity level is rated Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions (≤30°C/60% RH) without moisture-related reliability risks. This eliminates pre-reflow baking steps and reduces manufacturing complexity-confirmed in the Mechanical and Packaging section of the RF01243 Rev B datasheet.
What does the 'C' and 'e3' suffix mean in MXDA3KP8.0CAE3?
In MXDA3KP8.0CAE3, the 'C' suffix indicates bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients across its terminals. The 'e3' suffix denotes RoHS-compliant matte-tin terminal plating per EU Directive 2011/65/EU. Both identifiers are defined in the Part Nomenclature section on Page 2 of RF01243 Rev B and are physically marked on the device body.
Can MXDA3KP8.0CAE3 replace unidirectional TVS devices like MDA3KP8.0AE3 in existing designs?
No, MXDA3KP8.0CAE3 cannot directly replace unidirectional variants such as MDA3KP8.0AE3 without circuit review. As a bidirectional device, MXDA3KP8.0CAE3 clamps both polarities symmetrically and requires a center-tap ground connection (Pin 2), whereas unidirectional versions use anode-to-ground configuration. Swapping them may cause incorrect clamping behavior or increased standby leakage. Always verify layout, grounding scheme, and signal polarity before substitution-MXDA3KP8.0CAE3 is intended for differential or AC-coupled applications.
