Product details
Overview
MXLDA3KP36CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT protection per IEC61000-4-4. It features a 36 V reverse standoff voltage (VWM), 40.0–44.2 V breakdown voltage (V(BR)), and clamps to ≤58.1 V at 51.6 A peak pulse current (IPP).
For engineers reviewing the MXLDA3KP36CA datasheet, MXLDA3KP36CA pinout, MXLDA3KP36CA application, or MXLDA3KP36CA equivalent, this device serves as a high-reliability, RoHS-compliant TVS for telecom infrastructure power rails, industrial Ethernet ports, and DC power input stages requiring robust surge immunity with <5 ns response time and full MIL-PRF-19500 screening options.
Technical Context
The MXLDA3KP36CA is a bidirectional TVS diode array built using silicon avalanche technology, delivering sub-nanosecond response to transients. Its dual-anode/dual-cathode internal configuration enables symmetrical clamping across both polarities without external polarity constraints.
It operates over –55 °C to +150 °C junction temperature, supports 260 °C soldering per MIL-STD-750 Method 2026, and maintains ≤2 µA standby current (ID) at 36 V VWM - enabling low-power system monitoring while preserving surge capacity up to 3000 W at 10/1000 µs waveform.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 40.0–44.2 V @ 1 mA - ensures reliable avalanche initiation within defined tolerance band |
| VC @ IPP | ≤58.1 V @ 51.6 A - limits downstream voltage stress during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - delivers industry-standard high-energy surge handling for Class 1–4 IEC61000-4-5 |
| ID @ VWM | ≤2 µA - negligible leakage for battery-backed or low-quiescent systems |
| Response time | <5 ns - enables effective suppression of ESD (IEC61000-4-2) and fast EFT bursts |
| TJ/TSTG | –55 to +150 °C - supports deployment in extended-temperature industrial and aerospace environments |
Pinout & Package
MXLDA3KP36CA uses a DO-214AB (SMC) surface-mount package with two terminals: Pin 1 (cathode for one channel) and Pin 2 (anode for same channel); polarity is bidirectional, so either terminal may serve as anode or cathode depending on transient polarity. Body marking includes date code and "MXLDA3KP36CA" with dot indicating Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel A) | Primary current sink during positive transients; connects to protected line when used in bidirectional configuration |
| Pin 2 | Anode (Channel A) | Primary current sink during negative transients; completes symmetrical clamping path with Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating lines without polarity awareness |
| MIL-PRF-19500 screening option | Supports high-reliability 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 |
| UL94V-0 epoxy body | Ensures flame-retardant mechanical integrity under sustained overvoltage or fault conditions |
Applications
| Telecom Power Input | Industrial Ethernet PHY Port |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | 600 W PPP rating, SMB package (smaller footprint), 58.1 V VC @ 10.3 A IPP | Lower energy handling; suitable only for Class 1–2 IEC61000-4-5 or ESD-only use cases | Select when board space is constrained and surge threat level is limited to ESD/EFT, not lightning-induced surges |
| SMCJ36CA | 1500 W PPP rating, same SMC package, 58.1 V VC @ 25.8 A IPP | Half the peak power capability; requires derating for repeated surges above 1000 W | Choose when cost sensitivity outweighs need for full 3000 W margin, and thermal management limits full-rating operation |
Compared with SMBJ36CA and SMCJ36CA, the MXLDA3KP36CA provides double the surge energy capacity of SMCJ36CA and five times that of SMBJ36CA - making it uniquely suited for mission-critical secondary lightning protection where single-event survivability and minimal clamping overshoot are design priorities.

FAQ
What is the clamping voltage of MXLDA3KP36CA at its rated peak pulse current?
The MXLDA3KP36CA has a maximum clamping voltage (VC) of 58.1 V at 51.6 A peak pulse current (IPP), measured under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-rated surge event and is guaranteed across the operating temperature range of –55 °C to +150 °C. The MXLDA3KP36CA achieves this clamping performance while maintaining tight V(BR) tolerance (40.0–44.2 V) and low leakage (≤2 µA).
Is MXLDA3KP36CA RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP36CA is RoHS compliant, as confirmed by the 'e3' suffix in its full marking per Microsemi's nomenclature guide. The 'e3' designation specifies matte-tin plating per JEDEC J-STD-020B and compliance with Directive 2011/65/EU, including lead content below 1000 ppm. This applies to both terminal finish and packaging materials, and the device meets IPC/JEDEC moisture sensitivity Level 1 - eliminating dry-pack requirements for MXLDA3KP36CA handling and assembly.
How does the bidirectional construction of MXLDA3KP36CA affect its placement in a circuit?
The bidirectional construction of MXLDA3KP36CA allows it to be placed directly across any two points needing symmetrical overvoltage protection - such as differential signal pairs or AC-coupled lines - without regard to polarity. Unlike unidirectional TVS devices, MXLDA3KP36CA conducts during both positive- and negative-going transients, making it ideal for protecting balanced interfaces like RS-485, CAN FD, or Ethernet MDI pairs. Its pinout (Pin 1 = cathode, Pin 2 = anode) remains fixed, but the device functions identically regardless of orientation in the PCB layout.
Can MXLDA3KP36CA be used for primary lightning protection per IEC61000-4-5?
No, MXLDA3KP36CA is specified and tested for secondary lightning protection per IEC61000-4-5, not primary. It is intended for use downstream of primary protectors (e.g., gas discharge tubes or high-energy MOVs) in locations where induced surges have been attenuated. The device is validated for Class 1–4 testing with 42 Ω, 12 Ω, and 2 Ω source impedances - reflecting coupling paths typical of building wiring and equipment interconnections, not direct lightning strike exposure. Using MXLDA3KP36CA as sole protection in primary zones violates its design envelope and safety certification.
What thermal derating applies to MXLDA3KP36CA above 25 °C ambient?
MXLDA3KP36CA follows a linear thermal derating curve beginning at +25 °C case temperature, with peak pulse power (PPP) decreasing to 50% at +125 °C and zero at +150 °C junction temperature. Derating is based on Figure 3 in the RF01243 datasheet and assumes proper PCB copper area (≥1 sq. in. per pad) for heat spreading. At +85 °C ambient with standard FR-4 and 2 oz. copper, the MXLDA3KP36CA retains ~75% of its 3000 W rating - approximately 2250 W - provided no additional airflow or heatsinking is applied.
