Product details
Overview
MXLDA3KP7.5CA from Microsemi is a bidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. It features a 7.5 V reverse standoff voltage (VWM), 8.33–9.21 V breakdown voltage (V(BR)), 12.9 V maximum clamping voltage at 100 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXLDA3KP7.5CA datasheet, MXLDA3KP7.5CA pinout, MXLDA3KP7.5CA application, or MXLDA3KP7.5CA equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, bidirectional polarity, RoHS-compliant e3 matte-tin plating, and UL94V-0 void-free epoxy packaging.
Technical Context
The MXLDA3KP7.5CA implements a monolithic silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transients. Its clamping behavior is characterized at 10/1000 µs waveform with 3000 W peak pulse power rating and 100 A IPP, validated per MIL-PRF-19500 screening options when upscreened.
It supports secondary lightning protection per IEC61000-4-5 across multiple source impedances: Class 1–4 at 42 Ω, Class 1–3 at 12 Ω, and Class 4 only at 2 Ω - with explicit family-level validation confirmed for MDA3KP7.5CA in the referenced specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.5 V - Maximum continuous operating voltage before conduction begins; matches 5 V rail with margin or 6.3 V nominal DC bus. |
| V(BR) min–max | 8.33–9.21 V - Breakdown occurs within this range at 1 mA; ensures reliable turn-on above system operating peaks. |
| VC @ IPP | 12.9 V - Clamps 100 A transient to ≤12.9 V, limiting downstream stress on 15 V-rated ICs or MOSFETs. |
| IPP | 100 A - Peak surge current capability at 10/1000 µs; sufficient for IEC61000-4-5 Level 4 (4 kV) with 42 Ω source. |
| TJ range | –55 °C to +150 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| Package | DO-214AB (SMC) - Standardized surface-mount footprint with 21.03 × 22.05 mm body; compatible with automated reflow assembly. |
Pinout & Package
MXLDA3KP7.5CA uses a 2-pin DO-214AB (SMC) package with cathode-anode symmetry for bidirectional operation. Pin 1 is marked by a dot on the top surface and serves as one terminal of the TVS pair; Pin 2 is the complementary terminal. Polarity is non-directional due to bidirectional construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | One terminal of symmetrical avalanche junction; connects to protected line (e.g., RS-485 A/B or AC mains phase). |
| Pin 2 | Anode/Cathode (bidirectional) | Complementary terminal; completes bidirectional clamping path across differential or single-ended lines. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables symmetric transient suppression on AC lines, differential buses (e.g., CAN, RS-485), or ungrounded systems without polarity constraints. |
| 3000 W peak pulse power | Withstands 10/1000 µs surges up to 100 A - meets IEC61000-4-5 Level 4 (4 kV) with 42 Ω source impedance. |
| UL94V-0 void-free epoxy | Ensures flame resistance and mechanical integrity during surge events; eliminates internal delamination risks under thermal cycling. |
| e3 RoHS-compliant plating | Matte-tin termination enables lead-free reflow compatibility and eliminates tin whisker risk in high-reliability deployments. |
Applications
| Industrial Motor Drives | Telecom Power Interfaces |
|---|---|
Use Scenario: Protection of gate drivers and feedback sensors against inductive switching spikes in 24–48 V DC bus systems. IC Role / Device Role / Timing Role: Bidirectional TVS placed across DC bus inputs to clamp ±1 kV transients before they reach isolated gate drivers or ADC front-ends. Use Value: Limits voltage excursion to ≤12.9 V during 100 A surges, preventing latch-up or oxide damage in 15 V-rated control ICs. | Use Scenario: Secondary lightning protection on -48 V telecom rectifier outputs feeding remote radio units. IC Role / Device Role / Timing Role: Standoff-rated TVS installed at power entry point to absorb IEC61000-4-5 4 kV surges with 42 Ω source impedance. Use Value: Maintains system uptime by suppressing transients before they disrupt PMBus communication or cause brownout resets. |
| Automotive Body Control Modules | RS-485 Fieldbus Networks |
Use Scenario: Protection of LIN/CAN transceivers and microcontroller I/O against load dump and jump-start transients in under-hood ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS mounted directly at connector pins to shunt energy before it couples into signal conditioning circuitry. Use Value: Operates reliably from –55 °C to +150 °C, surviving engine bay thermal cycles while maintaining 7.5 V standoff for 12 V nominal systems. | Use Scenario: Differential transient suppression on long-haul RS-485 data lines exposed to EFT and induced RF in factory automation. IC Role / Device Role / Timing Role: Placed across A/B lines to clamp common-mode surges without distorting signal integrity below 12.9 V. Use Value: Sub-5 ns response time prevents data corruption during 4 kV EFT bursts (IEC61000-4-4), preserving bit error rate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5CA | 600 W rating (vs. 3000 W); 12.9 V VC @ 32.4 A IPP; DO-214AA package (smaller footprint). | Limited to lower-energy threats (IEC61000-4-5 Level 2); unsuitable for 42 Ω/4 kV testing. | Select SMBJ7.5CA only for space-constrained designs where surge energy is <100 mJ and clamping voltage tolerance allows. |
| 1.5KE7.5CA | 3000 W rating but axial-leaded DO-201 package; 12.9 V VC @ 100 A; no RoHS e3 marking by default. | Requires through-hole assembly; incompatible with SMT production; lacks traceable lot screening per MIL-PRF-19500. | Choose 1.5KE7.5CA only for legacy repair or prototyping where board real estate and reliability screening are secondary. |
Compared with SMBJ7.5CA and 1.5KE7.5CA, the MXLDA3KP7.5CA delivers identical clamping performance at full 3000 W rating while enabling automated SMT assembly, RoHS compliance, and high-reliability screening - critical for industrial and automotive production programs.

FAQ
What is the clamping voltage of MXLDA3KP7.5CA at its rated peak pulse current?
The MXLDA3KP7.5CA has a maximum clamping voltage (VC) of 12.9 V at 100 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is measured per standard test methods and guarantees that downstream circuitry sees no more than 12.9 V during a full-rated surge event, protecting 15 V-tolerant components effectively.
Is MXLDA3KP7.5CA suitable for IEC61000-4-5 Level 4 testing?
Yes, MXLDA3KP7.5CA is validated for IEC61000-4-5 Level 4 (4 kV) with 42 Ω source impedance, as confirmed in the RF01243 datasheet for the MDA3KPxxCA family. Its 3000 W rating and 100 A IPP ensure compliance when applied per test configuration guidelines and layout best practices.
Does MXLDA3KP7.5CA require dry pack moisture protection before reflow?
No, MXLDA3KP7.5CA has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it does not require dry pack storage or baking prior to reflow soldering. The device's void-free epoxy body and manufacturing process eliminate moisture absorption concerns typical of higher-MSL components.
How is polarity identified on the MXLDA3KP7.5CA package?
Polarity is indicated by a dot marking on the top surface of the MXLDA3KP7.5CA DO-214AB package, designating Pin 1. As a bidirectional device, both terminals function identically - the dot serves only for consistent orientation during placement, not functional polarity distinction.
What is the maximum operating junction temperature for MXLDA3KP7.5CA?
The MXLDA3KP7.5CA supports a junction temperature range of –55 °C to +150 °C, verified per absolute maximum ratings in the RF01243 datasheet. This enables use in under-hood automotive, industrial inverters, and outdoor telecom enclosures where ambient temperatures exceed 100 °C.
