Product details
Overview
MXLPLAD18KP150CAE3 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) rated for 18,000 W peak pulse power at 10/1000 μs, with 150 V reverse standoff voltage (VWM), 167–185 V breakdown voltage (V(BR)), and 243 V maximum clamping voltage (VC) at 75 A peak impulse current. It delivers high-reliability lightning and load dump protection in aerospace avionics per RTCA DO-160F Waveform 4 Level 4.
For engineers reviewing the MXLPLAD18KP150CAE3 datasheet, MXLPLAD18KP150CAE3 pinout, MXLPLAD18KP150CAE3 application, or MXLPLAD18KP150CAE3 equivalent, key selection criteria include bidirectional surge capability, IEC 61000-4-5 Class 1–5 secondary lightning compliance, thermal resistance (RθJC = 0.7 °C/W), RoHS-compliant e3 plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
This TVS diode employs an avalanche breakdown mechanism to clamp transients within nanoseconds, with <5 ns response time for bidirectional variants. Its low RθJC (0.7 °C/W) and void-free UL94V-0 epoxy package enable efficient heat dissipation during multi-stroke lightning events per RTCA DO-160 Section 22.
It meets IEC 61000-4-2 ESD (±30 kV contact), IEC 61000-4-4 EFT (4 kV), and IEC 61000-4-5 surge immunity (42 Ω, 12 Ω, and 2 Ω source impedances) - validated across Class 1–5 per standard. Pin injection protection is certified for DO-160F Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) at specified voltage grades.

Applications
| Aerospace Avionics Power Input | Automotive DC Bus Protection |
|---|---|
Use Scenario: 28 V DC power distribution in flight control computers and sensor modules subject to DO-160 lightning-induced transients. IC Role / Device Role / Timing Role: Primary transient voltage suppressor placed at board-level input filter stage to limit surge energy entering sensitive analog/digital circuitry. Use Value: Clamps 18 kW surges to ≤243 V within <5 ns, preventing latch-up or gate oxide damage in downstream PMICs and FPGAs. | Use Scenario: 24 V battery-fed ECUs in commercial vehicles exposed to ISO 7637-2 load dump and alternator switching spikes. IC Role / Device Role / Timing Role: Bidirectional TVS mounted directly at connector entry point to shunt both positive and negative polarity transients. Use Value: Withstands 1000 A surge current (IPP) and maintains VWM ≥150 V - exceeds 120 V load dump requirement with margin. |
| Industrial Motor Drive DC Link | Telecom Base Station Power Interface |
Use Scenario: DC link protection in servo drives where IGBT switching induces repetitive dv/dt transients and regenerative energy spikes. IC Role / Device Role / Timing Role: High-energy TVS placed across DC bus capacitors to absorb stored inductive energy during fault shutdown. Use Value: 18,000 W PPP rating handles cumulative heating from multi-stroke events; RθJC = 0.7 °C/W prevents thermal runaway under 0.05% duty cycle. | Use Scenario: -48 V DC power feed protection in 4G/5G remote radio units installed on cell towers subject to lightning-induced ground potential rise. IC Role / Device Role / Timing Role: Secondary surge protector downstream of gas discharge tube (GDT), clamping residual energy after primary diversion. Use Value: Certified for IEC 61000-4-5 Class 5 (42 Ω source) - ensures ≤243 V clamping even under worst-case coupling impedance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | 600 W PPP rating, SMA package, RθJC ≈ 25 °C/W - lower power density and thermal performance | Limited to single-stroke or low-duty-cycle surges; not qualified for DO-160 or MIL-PRF-19500 | Select when cost sensitivity outweighs aerospace/industrial reliability requirements and surge energy is <1 kJ |
| SMCJ150CA | 1500 W PPP rating, SMC package, RθJC ≈ 10 °C/W - 12× lower peak power than MXLPLAD18KP150CAE3 | Meets basic IEC 61000-4-5 Class 3 but lacks DO-160F Waveform 4/5A validation and upscreening support | Choose for commercial-grade industrial equipment where 18 kW capability and flight-certified validation are unnecessary |
Compared with SMBJ150CA and SMCJ150CA, MXLPLAD18KP150CAE3 delivers 30× higher peak pulse power, sub-5 ns response, and full DO-160F/IEC 61000-4-5 Class 5 qualification - making it uniquely suitable for mission-critical aerospace and high-energy industrial systems.

Does MXLPLAD18KP150CAE3 require moisture-sensitive handling?
No, MXLPLAD18KP150CAE3 is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it does not require dry pack packaging or baking prior to reflow soldering. Its void-free epoxy body and e3 matte-tin plating ensure robust SMT process compatibility without humidity-related risks.
What is the thermal resistance from junction to case for MXLPLAD18KP150CAE3?
The junction-to-case thermal resistance (RθJC) of MXLPLAD18KP150CAE3 is 0.7 °C/W, measured under defined mounting conditions on FR4 with recommended pad layout. This low value enables effective heat transfer to an external heatsink or copper pour, critical for sustaining multi-stroke 18 kW surge events.
Can MXLPLAD18KP150CAE3 be used in bidirectional AC signal lines?
Yes, MXLPLAD18KP150CAE3 is a bidirectional TVS (denoted by "CA" suffix) and is designed to protect AC-coupled or floating differential lines. Its symmetrical clamping behavior ensures equal protection for both polarities - verified by IEC 61000-4-5 testing at 42 Ω, 12 Ω, and 2 Ω source impedances.
