Product details
Overview
MXLDA3KP7.5CAE3 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 standoff voltage (VWM), 8.33–9.21 V breakdown voltage (V(BR)), 12.9 V clamping voltage at 232.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXLDA3KP7.5CAE3 datasheet, MXLDA3KP7.5CAE3 pinout, MXLDA3KP7.5CAE3 application, or MXLDA3KP7.5CAE3 equivalent, key selection criteria include bidirectional polarity, IEC61000-4-2/4-4/4-5 compliance, 10/1000 µs surge rating, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXLDA3KP7.5CAE3 implements a silicon avalanche diode structure optimized for sub-5 ns response time and low clamping ratio (VC/V(BR) ≈ 1.45). Its bidirectional configuration enables symmetrical clamping on both polarities without external circuitry, supporting protection of AC-coupled or floating signal lines.
Rated for 3000 W peak pulse power at 10/1000 µs waveform, it delivers 232.6 A IPP with <100 ps turn-on latency and maintains <2 µA standby current at 7.5 V, enabling low-power system monitoring during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.5 V - Maximum continuous operating voltage before clamping begins; matches 5 V or 3.3 V rail systems with margin. |
| V(BR) min–max | 8.33–9.21 V - Confirmed avalanche onset range at 1 mA; ensures predictable triggering under transients. |
| VC @ IPP | 12.9 V - Clamping voltage at 232.6 A peak pulse; limits downstream voltage stress during surge events. |
| IPP | 232.6 A - Peak impulse current supported at 10/1000 µs; validated per IEC61000-4-5 Class 1–4 with 2–42 Ω source impedance. |
| ID @ VWM | 100 µA - Standby leakage at rated standoff; negligible power loss in always-on protection circuits. |
| TJ range | –55 °C to +150 °C - Extended thermal envelope supports under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
Pinout & Package
MXLDA3KP7.5CAE3 uses a 2-pin DO-214AB (SMC) surface-mount package with void-free UL94V-0 epoxy body, matte-tin terminations, and polarity marked by a dot indicating Pin 1 as cathode for each TVS element. The device is bidirectional, so both terminals serve symmetric clamping roles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional) | Common terminal for symmetrical avalanche conduction; connects to protected line or ground reference depending on layout. |
| Pin 2 | Anode (Bidirectional) | Complementary terminal enabling equal clamping in both directions; no fixed polarity assignment required. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals or floating buses without polarity constraints or external diodes. |
| 3000 W 10/1000 µs rating | Validated surge handling for IEC61000-4-5 Class 4 (42 Ω source) and EFT/ESD immunity per IEC61000-4-2/4-4. |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace and defense applications via optional upscreening with lot traceability and 3σ ID testing. |
| Moisture Level 1 | No dry-pack requirement per IPC/JEDEC J-STD-020B; simplifies SMT assembly and reduces handling overhead. |
Applications
| Industrial Motor Drives | Telecom Power Interfaces |
|---|---|

IC Role / Device Role / Timing Role: Secondary surge limiter after front-end MOVs, absorbing residual energy with precise clamping. Use Value: Delivers repeatable 12.9 V clamping with <2 µA leakage, ensuring stable bias conditions for precision analog front-ends. |
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, 10.3 V clamping at 43.5 A IPP, DO-214AA package | Limited to lower-energy transients; not qualified for MIL-PRF-19500 screening | Select when cost sensitivity outweighs 3000 W surge requirement and high-reliability screening is unnecessary. |
| 1.5KE7.5CA | 1500 W rating, 12.0 V clamping at 125 A IPP, axial DO-201 package | Through-hole mounting only; higher thermal resistance than SMC; no moisture Level 1 rating | Choose for legacy through-hole designs where board space allows and reflow compatibility is not required. |
Compared with SMBJ7.5CA and 1.5KE7.5CA, MXLDA3KP7.5CAE3 delivers 5× higher peak power handling, superior thermal performance in SMT layouts, and formal upscreening pathways-making it optimal for mission-critical industrial and aerospace power interface protection.

FAQ
What is the clamping voltage of MXLDA3KP7.5CAE3 at its rated peak pulse current?
The MXLDA3KP7.5CAE3 has a maximum clamping voltage (VC) of 12.9 V at its rated peak pulse current (IPP) of 232.6 A under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in the datasheet and guarantees consistent overvoltage limiting during surge events without exceeding downstream component ratings.
Is MXLDA3KP7.5CAE3 suitable for IEC61000-4-5 Class 4 lightning surge testing?
Yes, MXLDA3KP7.5CAE3 is validated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance. Its 3000 W peak pulse power rating and 232.6 A IPP capability meet the 4 kV open-circuit voltage requirement for this class, as confirmed in the manufacturer's application notes and test reports.
Does MXLDA3KP7.5CAE3 require dry packing per J-STD-020B?
No, MXLDA3KP7.5CAE3 is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it does not require dry packing or baking prior to reflow soldering. This eliminates moisture-related assembly risks and simplifies manufacturing logistics for high-volume SMT production.
What does the "C" suffix in MXLDA3KP7.5CAE3 indicate?
The "C" suffix in MXLDA3KP7.5CAE3 explicitly denotes bidirectional polarity, confirming symmetrical clamping behavior across both voltage polarities. This distinguishes it from unidirectional variants like MXLDA3KP7.5AE3 and enables use in AC-coupled or floating signal paths without polarity-aware layout constraints.
Can MXLDA3KP7.5CAE3 be used in automotive under-hood applications?
Yes, MXLDA3KP7.5CAE3 supports junction temperatures from –55 °C to +150 °C and is qualified for high-reliability environments. Its thermal robustness, MIL-PRF-19500 upscreening option, and surge performance make it suitable for under-hood automotive applications such as body control modules and engine control unit power inputs.
