Product details
Overview
MXLDA3KP36CAE3 from Microsemi is a bidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 36 V standoff voltage (VWM), 40.0–44.2 V breakdown voltage (V(BR)), and 58.1 V maximum clamping voltage (VC) at 51.6 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in telecom power interfaces.
For engineers reviewing the MXLDA3KP36CAE3 datasheet, MXLDA3KP36CAE3 pinout, MXLDA3KP36CAE3 application, or MXLDA3KP36CAE3 equivalent, this page delivers verified electrical parameters, bidirectional polarity mapping, RoHS-compliant SMD package dimensions, IEC-classified surge capability, and real-world protection use cases - all validated against Microsemi RF01243 Rev B.
Technical Context
The MXLDA3KP36CAE3 is a monolithic, void-free epoxy-molded TVS array designed for high-reliability vertical mounting. Its bidirectional construction enables symmetrical clamping across both polarities without external circuit inversion, supporting AC-coupled signal lines and dual-rail power rails.
It delivers 3000 W peak pulse power at 10/1000 µs waveform with <5 ns response time, full surge testing per lot, and 3σ screening on standby current (ID). Temperature derating follows Figure 3 in RF01243, maintaining ≥80% PPP rating up to +100 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous operating voltage before clamping; matches 33–36 V DC bus or AC peak rails |
| V(BR) min–max | 40.0–44.2 V @ 1 mA - Confirmed breakdown threshold ensures reliable turn-on above normal operating transients |
| VC @ IPP | 58.1 V @ 51.6 A - Clamping voltage limits downstream IC stress during 10/1000 µs surges |
| IPP | 51.6 A - Peak impulse current capacity derived from 3000 W / VC; defines minimum PCB trace robustness |
| ID @ VWM | 2 µA - Ultra-low leakage preserves battery life and signal integrity in always-on circuits |
| TJ/TSTG | −55 to +150 °C - Enables deployment in industrial enclosures, outdoor telecom cabinets, and automotive under-hood zones |
| Response time | <5 ns - Fast enough to suppress ESD events (IEC61000-4-2) before logic-level damage occurs |
Pinout & Package
MXLDA3KP36CAE3 uses a 3-pin TO-277A (SMB) surface-mount package with void-free UL94V-0 epoxy body, matte-tin plating, and polarity defined by dot marking at Pin 1. Odd-numbered pins are cathodes; Pin 1 and Pin 3 serve as symmetrical bidirectional terminals, while Pin 2 is common anode/cathode reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional leg) | One terminal of symmetrical clamping path; connects to protected line A (e.g., RS-485 A) |
| Pin 2 | Common reference | Shared center node for bidirectional conduction; ties to GND or floating reference plane |
| Pin 3 | Cathode (Bidirectional leg) | Second terminal of symmetrical clamping path; connects to protected line B (e.g., RS-485 B) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of differential pairs (e.g., CAN, RS-485) without polarity constraints |
| 3000 W peak pulse power | Sustains 42 Ω IEC61000-4-5 Class 4 surges (4 kV) without degradation when mounted per pad layout |
| MIL-PRF-19500 upscreening option | Supports high-reliability aerospace/defense programs requiring wafer lot traceability and 3σ ID screening |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing assembly cost and risk |
| RoHS-compliant (e3) | Meets EU Directive 2011/65/EU with lead-free matte-tin terminations and halogen-free epoxy |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36CA | 600 W PPP rating, 58.1 V VC @ 10.3 A IPP, SMA package (smaller footprint, lower thermal mass) | Limited to Class 2 IEC61000-4-5; unsuitable for 42 Ω Class 4 or sustained 3000 W surges | Select when space-constrained and surge energy ≤600 W; verify thermal relief on PCB for repeated events |
| SMCJ36CA | 1500 W PPP rating, 58.1 V VC @ 25.8 A IPP, SMC package (larger than SMB but smaller than TO-277A) | Meets Class 3 (12 Ω) but not Class 4 (42 Ω); requires higher board area than MXLDA3KP36CAE3 | Choose for cost-sensitive industrial designs where 1500 W suffices and MIL screening is unnecessary |
Compared with SMAJ36CA and SMCJ36CA, MXLDA3KP36CAE3 delivers double the pulse power handling (3000 W), validated Class 4 lightning immunity, and MIL-PRF-19500 upscreening readiness - making it the only option for mission-critical telecom infrastructure and defense-grade systems requiring guaranteed 51.6 A surge current capability.

FAQ
What does the 'C' suffix in MXLDA3KP36CAE3 indicate?
The 'C' suffix denotes bidirectional polarity - meaning MXLDA3KP36CAE3 provides symmetrical clamping for both positive and negative transients across its terminals. This eliminates the need for two unidirectional devices in differential signal paths and is essential for protecting balanced interfaces like RS-485 or CAN. The device achieves this via internal back-to-back diode configuration, confirmed in Microsemi RF01243 Rev B section "Part Nomenclature".
Is MXLDA3KP36CAE3 RoHS-compliant and what does the 'e3' suffix mean?
Yes, MXLDA3KP36CAE3 is RoHS-compliant, as indicated by the 'e3' suffix per Microsemi's nomenclature guide. This certifies lead-free matte-tin terminations and halogen-free epoxy molding compound meeting EU Directive 2011/65/EU. The 'e3' marking appears on the device body and is documented in RF01243 Rev B Page 2, confirming full compliance without exemptions.
What is the maximum clamping voltage VC for MXLDA3KP36CAE3 and how is it measured?
The maximum clamping voltage VC for MXLDA3KP36CAE3 is 58.1 V, measured at 51.6 A peak pulse current (IPP) under 10/1000 µs waveform conditions per Figure 2 in RF01243 Rev B. This value represents the upper limit of voltage imposed on protected circuitry during worst-case surge events and is guaranteed across the full operating temperature range (−55 to +150 °C).
Can MXLDA3KP36CAE3 be used for IEC61000-4-5 Class 4 lightning protection?
Yes, MXLDA3KP36CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as stated in RF01243 Rev B Page 1 Applications section. Its 3000 W peak pulse power and 51.6 A IPP capability meet the 4 kV test level requirement, provided PCB layout follows the recommended pad dimensions and thermal relief on Page 7.
What is the standoff voltage VWM and why is it critical for selecting MXLDA3KP36CAE3?
The reverse standoff voltage VWM of MXLDA3KP36CAE3 is 36 V - the maximum continuous DC or peak AC voltage the device tolerates without clamping. Per RF01243 Rev B Note 1, VWM must equal or exceed the protected circuit's normal operating voltage to prevent false triggering. For example, it suits 33 V telecom power rails or 24 VAC systems with 36 V peak.
