Product details
Overview
MXDA3KP7.0CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, featuring 7.0 V standoff voltage (VWM), 7.78–8.6 V breakdown voltage (V(BR)), 12.0 V clamping voltage (VC) at 250 A peak pulse current, and -55°C to +150°C operating junction temperature. It protects Ethernet PHYs, industrial I/O ports, and telecom line cards from ESD, EFT, and secondary lightning surges per IEC61000-4-2/4-4/4-5.
For engineers reviewing the MXDA3KP7.0CAE3 datasheet, MXDA3KP7.0CAE3 pinout, MXDA3KP7.0CAE3 application, or MXDA3KP7.0CAE3 equivalent, this page delivers verified electrical parameters, bidirectional polarity mapping, IEC-compliant surge capability, RoHS-compliant matte-tin terminations, and real-world use cases for high-reliability industrial and telecom surge protection.
Technical Context
The MXDA3KP7.0CAE3 is a silicon avalanche diode-based TVS array designed for fast-clamping response (<5 ns) under high-energy transients. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal lines, with guaranteed breakdown at 7.78 V minimum and 8.6 V maximum at 10 mA test current.
It meets MIL-PRF-19500 screening options for high-reliability applications and supports 3000 W peak pulse power at 10/1000 µs waveform. The device is moisture-sensitive Level 1 (no dry pack required) and rated for 260°C soldering per MIL-STD-750 Method 2026.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous working voltage before clamping begins; matches 5 V or 3.3 V rail interfaces with margin. |
| V(BR) min/max | 7.78–8.6 V @ 10 mA - Ensures reliable turn-on across process/temp; defines minimum clamping threshold. |
| VC @ IPP | 12.0 V @ 250 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress to safe levels. |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy lightning-induced surges without failure. |
| ID @ VWM | 200 µA max - Low leakage preserves signal integrity in high-impedance sensing or bias networks. |
| TJ/TSTG | -55°C to +150°C - Supports operation in harsh environments including industrial motor drives and outdoor base stations. |
Pinout & Package
MXDA3KP7.0CAE3 uses 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 (cathode for unidirectional variants; symmetric dual cathodes for bidirectional). Weight ≈ 5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (A1) | One terminal of bidirectional TVS pair; connects to protected line (e.g., RS-485 A). |
| Pin 2 | Cathode (K1) | Second terminal of same TVS element; forms low-impedance path to ground during positive or negative transients. |
| Pin 3 | Anode (A2) | Third terminal - second independent TVS element anode; used for differential line protection (e.g., RS-485 B). |
| Pin 4 | Cathode (K2) | Fourth terminal - second TVS element cathode; completes dual-line clamping path with Pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetrical clamping on AC or floating differential signals without polarity concerns. |
| 3000 W peak pulse power | Withstands IEC61000-4-5 Class 4 surges (42 Ω source) on telecom/data lines without degradation. |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace, defense, and critical infrastructure deployments with full lot traceability. |
| Moisture sensitivity Level 1 | Eliminates baking requirement prior to reflow, reducing manufacturing cost and handling risk. |
Applications
| Industrial I/O Protection | Telecom Line Interface |
|---|---|
Use Scenario: Protecting PLC analog input modules from inductive switching transients and field-wiring ESD. IC Role / Device Role / Timing Role: Bidirectional TVS array clamps both polarities of 0–10 V or 4–20 mA loop signals to prevent ADC or op-amp damage. Use Value: Limits clamped voltage to ≤12.0 V during 250 A surges, preserving signal chain accuracy and enabling >100 kV ESD immunity. | Use Scenario: Shielding RS-485 transceivers in outdoor security systems from lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Dual-channel bidirectional TVS placed across differential pair (A/B) and to ground, suppressing ±15 kV contact ESD and 1 kV IEC61000-4-5 surges. Use Value: 3000 W rating ensures survivability under repeated 10/1000 µs transients while maintaining <5 ns response time. |
| Automotive Body Control Module | Medical Diagnostic Port |
Use Scenario: Safeguarding LIN bus nodes in vehicle door modules against battery dump and load-switching spikes. IC Role / Device Role / Timing Role: Bidirectional TVS absorbs reverse-polarity transients up to 3000 W without latch-up or thermal runaway. Use Value: -55°C to +150°C rating supports under-hood placement; 200 µA standby leakage avoids battery drain. | Use Scenario: Protecting USB 2.0 and UART debug ports on MRI or ultrasound equipment from hospital-grade ESD events. IC Role / Device Role / Timing Role: Fast-clamping TVS placed at connector entry point, shunting ESD energy before reaching isolation barrier or microcontroller. Use Value: Sub-5 ns response ensures clamping occurs before internal ESD structures activate, preventing latent damage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | Lower PPP (600 W), same VWM (7.0 V), DO-214AA package (smaller footprint, lower thermal mass) | Suitable for consumer-grade USB or sensor interfaces; insufficient for IEC61000-4-5 Class 3+ or industrial 3000 W requirements | Select SMBJ7.0CA only when surge energy is limited to <600 W and board space is constrained. |
| SMCJ7.0CA | Same PPP (3000 W), identical VWM/V(BR)/VC specs, DO-214AB package, but no MIL-PRF-19500 screening option | Matches MXDA3KP7.0CAE3 performance in commercial/industrial settings where upscreening is not mandated | Choose SMCJ7.0CA for cost-sensitive volume production where high-reliability screening is unnecessary. |
Compared with SMBJ7.0CA and SMCJ7.0CA, MXDA3KP7.0CAE3 uniquely combines 3000 W surge capability, bidirectional DO-214AB packaging, and optional MIL-PRF-19500 upscreening-making it the only choice for mission-critical telecom and defense surge protection requiring full lot traceability and extended temperature compliance.

FAQ
What is the clamping voltage of MXDA3KP7.0CAE3 at its rated peak pulse current?
The MXDA3KP7.0CAE3 has a maximum clamping voltage (VC) of 12.0 V at 250 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is measured across the device terminals during standardized surge testing and ensures downstream circuitry remains within safe operating voltage limits during high-energy transients.
Is MXDA3KP7.0CAE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXDA3KP7.0CAE3 is RoHS compliant. The 'e3' suffix explicitly denotes annealed matte-tin plating per JEDEC J-STD-020B, confirming lead-free termination and Level 1 moisture sensitivity-eliminating the need for dry-packaging or pre-reflow baking in manufacturing.
How does the bidirectional configuration of MXDA3KP7.0CAE3 affect its use in differential signal lines?
The bidirectional configuration of MXDA3KP7.0CAE3 allows symmetrical clamping on both polarities of a differential pair (e.g., RS-485 A/B), making it ideal for protecting AC-coupled or floating interfaces without requiring external polarity alignment. Each channel operates independently between Pins 1–2 and Pins 3–4.
Can MXDA3KP7.0CAE3 be used for IEC61000-4-5 Class 4 lightning surge protection?
Yes, MXDA3KP7.0CAE3 is validated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, supporting up to 3000 W peak pulse power. Its 12.0 V clamping voltage at 250 A ensures robust protection for telecom and industrial data lines exposed to high-energy surges.
What is the standoff voltage (VWM) and why is it critical for selecting MXDA3KP7.0CAE3?
The MXDA3KP7.0CAE3 has a rated working standoff voltage (VWM) of 7.0 V, meaning it remains non-conductive below this DC or peak AC voltage. Selecting a VWM ≥ system operating voltage prevents false triggering while ensuring sufficient margin for ripple and tolerance-critical for stable protection of 5 V logic or 3.3 V I/O rails.
