Product details
Overview
MXLDA3KP7.0CAE3 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 7.0 V reverse standoff voltage (VWM), 7.78–8.6 V breakdown voltage (V(BR)), 12.0 V maximum clamping voltage at 250 A peak pulse current, and operates from −55 °C to +150 °C - deployed in telecom power interfaces and industrial I/O protection circuits.
For engineers reviewing the MXLDA3KP7.0CAE3 datasheet, MXLDA3KP7.0CAE3 pinout, MXLDA3KP7.0CAE3 application, or MXLDA3KP7.0CAE3 equivalent, key selection criteria include bidirectional polarity, 12.0 V clamping at 250 A, RoHS-compliant matte-tin terminations, MIL-PRF-19500 upscreening eligibility, and compatibility with IEC61000-4-2/4-4/4-5 surge test waveforms.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transient overvoltages within nanoseconds. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal lines, and its 10/1000 µs waveform rating supports IEC61000-4-5 Class 1–4 secondary lightning testing with 2 Ω, 12 Ω, and 42 Ω source impedances.
The device achieves <5 ns response time from 0 V to V(BR) min, delivers 3000 W peak pulse power, and maintains ≤200 µA standby current at VWM. Its void-free UL94V-0 epoxy package ensures mechanical robustness and thermal stability across extended temperature cycling in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - maximum continuous operating voltage before clamping initiates |
| V(BR) min/max | 7.78–8.6 V @ 10 mA - guaranteed avalanche conduction threshold range |
| VC @ IPP | 12.0 V @ 250 A - clamped voltage during full-rated 10/1000 µs surge |

Pinout & Package
MXLDA3KP7.0CAE3 is housed in a 3-pin surface-mount plastic package (case outline per RF01243, Page 7). Pin 1 is marked by a dot on the top surface; odd-numbered pins are cathodes per internal diode polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of first TVS element | Common anode configuration enables bidirectional clamping between Pins 1–2 and Pins 2–3 |
| Pin 2 | Anode (common center terminal) | Shared anode node - connects to ground or reference plane in differential protection schemes |
| Pin 3 | Cathode of second TVS element | Completes symmetrical pair; used with Pin 2 to protect balanced lines (e.g., RS-485, CAN FD) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or floating data lines without polarity constraints (e.g., Ethernet PHY, USB D+/D−) |
| 3000 W peak pulse rating | Sustains 10/1000 µs surges up to 250 A - meets IEC61000-4-5 Level 4 with 42 Ω source impedance |
| MIL-PRF-19500 screening option | Supports high-reliability qualification including lot traceability, 3σ ID screening, and surge testing per military standard |
| UL94V-0 epoxy body | Self-extinguishing thermoset encapsulation prevents flame propagation in enclosed industrial enclosures |
| Moisture sensitivity Level 1 | No dry-pack or bake-out required prior to reflow - simplifies SMT assembly and reduces process risk |
Applications
| Telecom Power Interface Protection | Industrial RS-485 Transceiver Protection |
|---|---|
Use Scenario: Protecting DC power feeds to remote radio units against induced lightning surges and switching transients. IC Role / Device Role / Timing Role: Bidirectional TVS array placed across +V and GND rails to clamp common-mode overvoltage events. Use Value: Limits rail voltage to ≤12.0 V during 250 A surges, preventing damage to downstream DC/DC converters and PMICs. | Use Scenario: Safeguarding RS-485 transceivers in factory automation networks exposed to motor drive noise and ground bounce. IC Role / Device Role / Timing Role: Differential-line TVS connected between A/B bus lines and local ground to suppress EFT bursts and fast transients. Use Value: Clamps differential surges to <12.0 V within <5 ns, preserving signal integrity and avoiding receiver latch-up. |
| Automotive Body Control Module I/O | Medical Patient Monitor Sensor Inputs |
Use Scenario: Protecting LIN bus and switch inputs in BCMs subjected to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS placed on each switched input line referenced to chassis ground. Use Value: Withstands 3000 W surges while maintaining ≤200 µA leakage - avoids false triggering of low-current wake-up circuits. | Use Scenario: Shielding analog front-end inputs of patient monitors from ESD events during clinical handling. IC Role / Device Role / Timing Role: Low-leakage TVS on biopotential electrode paths to prevent amplifier saturation and baseline shift. Use Value: 200 µA max ID at 7.0 V ensures minimal DC offset error in high-gain instrumentation amplifiers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0CA | 600 W rating, 10.5 V clamping at 43.3 A, DO-214AC package | Lower power handling limits use to sub-1 kV surge environments; unsuitable for IEC61000-4-5 Class 4 | Select when board space is constrained and surge threat level is limited to ESD/EFT only |
| SMCJ7.0CA | 1500 W rating, 12.0 V clamping at 125 A, DO-214AB package | Half the peak power of MXLDA3KP7.0CAE3; requires derating above 85 °C ambient | Choose where cost sensitivity outweighs need for full 3000 W margin in non-military designs |
Compared with SMAJ7.0CA and SMCJ7.0CA, MXLDA3KP7.0CAE3 delivers double the surge energy capacity and maintains clamping performance across −55 °C to +150 °C - making it suitable for aerospace-grade power interface hardening where single-event failure tolerance is mandatory.

FAQ
What does the 'C' in MXLDA3KP7.0CAE3 indicate?
The 'C' suffix denotes bidirectional polarity - meaning MXLDA3KP7.0CAE3 contains two back-to-back avalanche diodes enabling symmetrical clamping for AC signals or floating differential lines. This differs from unidirectional variants (e.g., MXLDA3KP7.0AE3), which clamp only in one direction relative to ground. The C-type configuration is essential for protecting RS-485, CAN, or Ethernet interfaces where voltage polarity reverses during normal operation.
Is MXLDA3KP7.0CAE3 compatible with lead-free reflow processes?
Yes, MXLDA3KP7.0CAE3 carries the e3 marking, confirming RoHS-compliant matte-tin terminations qualified for Pb-free soldering at 260 °C for 10 seconds. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, so no pre-bake is required prior to reflow - reducing manufacturing complexity and eliminating moisture-related popcorning risks during assembly.
How does MXLDA3KP7.0CAE3 perform under elevated temperature conditions?
MXLDA3KP7.0CAE3 maintains full 3000 W surge capability at 25 °C, with linear derating beginning at 25 °C per Figure 3 in RF01243. At +125 °C junction temperature, its peak pulse power drops to approximately 65% of rated value (~1950 W), while clamping voltage remains stable within specification. This behavior is verified across the full −55 °C to +150 °C operating range, supporting deployment in engine control units and outdoor base stations.
Can MXLDA3KP7.0CAE3 be used for IEC61000-4-5 Level 4 testing?
Yes, MXLDA3KP7.0CAE3 is explicitly rated for IEC61000-4-5 Level 4 secondary lightning immunity with 42 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B. Its 250 A peak pulse current and 12.0 V clamping voltage ensure compliance when tested using the 10/1000 µs waveform - provided layout minimizes parasitic inductance and grounding is low-impedance.
What is the significance of the 'MXL' prefix in MXLDA3KP7.0CAE3?
The 'MXL' prefix identifies this as a Microsemi high-reliability variant of the MDA3KP7.0CA family - indicating enhanced process controls, wafer-level lot traceability, and optional MIL-PRF-19500 screening. Unlike standard MDA3KP7.0CA parts, MXLDA3KP7.0CAE3 undergoes additional 3σ statistical screening on standby current (ID) and full surge validation, making it suitable for avionics and defense subsystems where field failure rates must remain below 100 FIT.
