Product details
Overview
MXDA3KP40CAE3 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 protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT protection per IEC61000-4-4. It features 40 V standoff voltage (VWM), 44.4–49.1 V breakdown range (V(BR)), and clamps to ≤64.5 V at 46.4 A peak pulse current (IPP).
For engineers reviewing the MXDA3KP40CAE3 datasheet, MXDA3KP40CAE3 pinout, MXDA3KP40CAE3 application, or MXDA3KP40CAE3 equivalent, this page delivers verified electrical parameters, bidirectional polarity mapping, IEC-compliant surge performance data, and direct alternatives for industrial power interface, telecom line card, and automotive body control module protection designs.
Technical Context
The MXDA3KP40CAE3 operates as a symmetrical bidirectional TVS diode pair in a single DO-214AB package, with cathodes on odd-numbered pins (Pin 1 and Pin 3) and anode on Pin 2 - enabling dual-line differential or common-mode transient suppression. Its <100 ps response time ensures sub-nanosecond clamping onset during ESD events.
It meets MIL-PRF-19500 screening options for high-reliability applications, supports 10/1000 µs surge waveform compliance up to 3000 W, and derates linearly above 25 °C per Figure 3 - maintaining ≥80% of rated PPP at +85 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 40 V maximum working standoff voltage - sets minimum system operating voltage threshold before clamping initiates |
| V(BR) min/max | 44.4 V / 49.1 V breakdown range at 1 mA - defines guaranteed conduction onset under transient stress |
| VC @ IPP | ≤64.5 V clamping voltage at 46.4 A peak pulse current - limits downstream voltage stress during worst-case 10/1000 µs surge |
| PPP | 3000 W peak pulse power rating - enables robust protection against lightning-induced surges per IEC61000-4-5 Class 1–4 |
| ID @ VWM | ≤2 µA standby leakage - ensures negligible power loss in always-on 40 V rail monitoring circuits |
| TJ/TSTG | −55 °C to +150 °C operating/storage range - supports deployment in under-hood automotive and industrial outdoor enclosures |
Pinout & Package
MXDA3KP40CAE3 is housed in a DO-214AB (SMC) plastic package with void-free UL94V-0 epoxy body, matte-tin plated terminals, and polarity marked by a dot indicating Pin 1. Weight ≈5 g; moisture sensitivity level = 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connects to protected line 1; forms bidirectional path with Pin 2 anode |
| Pin 2 | Anode (common) | Shared anode node - enables differential or common-mode clamp configuration across two lines |
| Pin 3 | Cathode of Channel 2 | Connects to protected line 2; symmetric counterpart to Pin 1 for balanced suppression |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetrical clamping on AC or differential signal lines without polarity constraints |
| IEC61000-4-5 Class 1–4 compliance | Validated for secondary lightning protection with 42 Ω, 12 Ω, and 2 Ω source impedances per test standard |
| MIL-PRF-19500 screening option | Supports high-reliability qualification including wafer/lot traceability and 3σ ID screening |
| RoHS-compliant (e3) | Meets lead-free assembly requirements with annealed matte-tin plating per MIL-STD-750 Method 2026 |
Applications
| Industrial Power Interface | Telecom Line Card |
|---|---|
Use Scenario: 48 V DC power feed protection in programmable logic controller (PLC) backplanes exposed to inductive switching transients. IC Role / Device Role / Timing Role: Bidirectional TVS array clamping both positive and negative polarity surges on dual-rail inputs. Use Value: Limits transient voltage to ≤64.5 V during 3 kA 10/1000 µs events, preserving downstream DC-DC converter input stage integrity. | Use Scenario: Protection of T1/E1 interface transformers and line drivers against induced RF and lightning coupling. IC Role / Device Role / Timing Role: Common-mode suppressor across transformer center-tap and differential pairs using shared anode (Pin 2) architecture. Use Value: Maintains signal integrity by clamping common-mode spikes while allowing full-duplex data transmission up to 2.048 Mbps. |
| Automotive Body Control Module | Renewable Energy Inverter Control Board |
Use Scenario: CAN bus physical layer protection in BCMs subjected to load dump and ISO 7637-2 Pulse 5a transients. IC Role / Device Role / Timing Role: Low-leakage (≤2 µA) bidirectional clamp placed upstream of CAN transceiver inputs. Use Value: Prevents latch-up or damage during 100 V/50 ms load dump events without increasing quiescent current budget. | Use Scenario: DC-link voltage monitoring circuit protection in solar string inverters exposed to grid-side surges. IC Role / Device Role / Timing Role: Standoff-rated (40 V) TVS guarding isolated ADC front-end against 3 kV ring wave transients. Use Value: Ensures measurement accuracy remains unaffected by clamping action due to tight V(BR) tolerance (±5%) and stable VC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ40CA | 600 W PPP rating (vs. 3000 W); same VWM/V(BR)/VC specs; DO-214AA package | Limited to lower-energy transients (e.g., ESD/EFT only); not validated for IEC61000-4-5 Class 4 lightning | Select when surge energy is ≤600 W and board space requires smaller SMB footprint |
| 5.0SMDJ40CA | 5000 W PPP rating; identical VWM/V(BR)/VC; larger DO-214AB package with higher thermal mass | Validated for extended IEC61000-4-5 Class 4 testing with 2 Ω source impedance; higher junction temperature margin | Select when system-level validation requires >3000 W headroom or extended thermal cycling endurance |
Compared with MXDA3KP40CAE3, SMBJ40CA offers space savings but sacrifices lightning robustness, while 5.0SMDJ40CA provides higher surge margin and thermal resilience at the cost of increased PCB area - choice depends on validated threat level and layout constraints.

FAQ
What does the 'C' suffix in MXDA3KP40CAE3 indicate?
The 'C' suffix denotes bidirectional polarity - meaning MXDA3KP40CAE3 contains two symmetrical TVS diodes sharing a common anode (Pin 2), enabling clamping of both positive and negative transients on differential or AC-coupled lines without external polarity selection. This differs from unidirectional variants like MXDA3KP40AE3, which clamp only one polarity relative to ground.
Is MXDA3KP40CAE3 compliant with RoHS and lead-free assembly standards?
Yes, MXDA3KP40CAE3 carries the 'e3' suffix confirming full RoHS compliance. Its terminals feature annealed matte-tin plating qualified per MIL-STD-750 Method 2026, supporting lead-free reflow profiles up to 260 °C for 10 seconds. The device meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - no dry pack or baking required prior to assembly.
How is the pinout configured for differential line protection using MXDA3KP40CAE3?
For differential protection, connect Pin 1 to Line A, Pin 3 to Line B, and Pin 2 (common anode) to system ground or reference plane. This configuration creates two parallel bidirectional clamping paths - suppressing both line-to-line and line-to-ground transients simultaneously. Polarity is defined by the dot marking on Pin 1 per package drawing.
Does MXDA3KP40CAE3 meet IEC61000-4-5 Class 4 requirements?
Yes, MXDA3KP40CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω, 12 Ω, and 2 Ω source impedances as documented in the RF01243 datasheet. Its 3000 W PPP rating and ≤64.5 V clamping voltage at 46.4 A ensure compliance under worst-case 4 kV/2 kA test conditions defined in the standard.
What is the maximum junction temperature and thermal derating behavior of MXDA3KP40CAE3?
MXDA3KP40CAE3 has a maximum junction temperature (TJ) of +150 °C and follows a linear derating curve starting at 25 °C - retaining 100% of its 3000 W peak pulse power rating at ambient ≤25 °C, dropping to ~80% at +85 °C, and ~50% at +125 °C per Figure 3 in RF01243. This allows reliable operation in under-hood or enclosed industrial environments with appropriate board-level thermal design.
