Product details
Overview
MPLAD18KP60CAE3 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial systems. It delivers 18,000 W peak pulse power at 10/1000 μs, features a 60 V reverse standoff voltage (VWM), clamps to ≤96.8 V at 186 A peak impulse current (IPP), and meets RTCA DO-160F Waveform 4 Level 4 and IEC 61000-4-5 Class 1–4 lightning standards.
For engineers reviewing the MPLAD18KP60CAE3 datasheet, MPLAD18KP60CAE3 pinout, MPLAD18KP60CAE3 application, or MPLAD18KP60CAE3 equivalent, key selection criteria include its bidirectional polarity, 60 V working voltage, low thermal resistance (RθJC = 0.7 °C/W), RoHS-compliant e3 plating, and qualification per AEC-Q101 and MIL-PRF-19500 screening options.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating above its 66.7–73.7 V breakdown voltage (V(BR)) to divert transients away from sensitive components. Its metal-base package enables direct thermal coupling to heatsinks, supporting sustained energy dissipation under multi-stroke lightning events per RTCA DO-160 Section 22.
The device is characterized for bidirectional operation, with symmetrical clamping behavior in both polarities, and exhibits a temperature coefficient of breakdown voltage (αV(BR)) of ±70 mV/°C. It complies with ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and secondary lightning (IEC 61000-4-5) immunity requirements across multiple source impedances (2 Ω, 12 Ω, 42 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 18,000 W @ 10/1000 μs - sustains aircraft-grade lightning surges without failure |
| Reverse Standoff Voltage (VWM) | 60 V - maximum continuous DC or RMS operating voltage before clamping initiates |
| Breakdown Voltage (V(BR)) | 66.7–73.7 V @ I(BR) - precise conduction threshold ensuring reliable overvoltage detection |
| Max Clamping Voltage (VC) | 96.8 V @ 186 A IPP - limits downstream voltage stress during worst-case transients |
| Thermal Resistance (RθJC) | 0.7 °C/W - enables efficient heat transfer to heatsink for repeated surge duty cycles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | 600 W PPP rating (vs. 18,000 W), DO-214AA package, RθJC ≈ 40 °C/W | Limited to consumer/industrial low-energy transients; not suitable for DO-160 or ISO 7637-2 compliance | Select SMBJ60CA only for cost-sensitive non-safety applications where surge energy remains below 100 mJ. |
| SMCJ60CA | 1500 W PPP rating (vs. 18,000 W), DO-214AB package, RθJC ≈ 15 °C/W | Meets IEC 61000-4-5 Class 3 but fails DO-160F Level 4 and multi-stroke lightning endurance | Choose SMCJ60CA for space-constrained designs needing higher energy handling than SMBJ but lacking aviation-grade requirements. |
Compared with SMBJ60CA and SMCJ60CA, the MPLAD18KP60CAE3 provides 12× and 12× greater peak pulse power respectively, enabling single-device compliance with RTCA DO-160F and ISO 7637-2 while maintaining lower thermal resistance for repeatable surge endurance.

FAQ
What is the clamping voltage of MPLAD18KP60CAE3 at its rated peak pulse current?
The MPLAD18KP60CAE3 has a maximum clamping voltage (VC) of 96.8 V when subjected to its peak impulse current (IPP) of 186 A under 10/1000 μs waveform conditions. This value is measured across the device terminals during standardized surge testing and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Is MPLAD18KP60CAE3 qualified for automotive applications?
Yes, MPLAD18KP60CAE3 is AEC-Q101 qualified and explicitly rated for automotive load dump protection per ISO 7637-2 Pulse 5a/b. Its 60 V VWM aligns with 12 V system architectures, and its 18,000 W PPP rating exceeds the energy demands of alternator-induced transients, making it suitable for powertrain and body control modules.
Does MPLAD18KP60CAE3 require a heatsink for reliable operation?
Yes - the MPLAD18KP60CAE3 relies on thermal conduction through its metal baseplate (cathode) to achieve its specified RθJC of 0.7 °C/W. Mounting the baseplate directly to a thermally optimized PCB copper pour or external heatsink is mandatory to prevent junction overheating during repeated surges; operation without thermal management violates its maximum ratings.
How does the CA suffix in MPLAD18KP60CAE3 indicate device polarity?
The "CA" suffix in MPLAD18KP60CAE3 denotes bidirectional construction, meaning the device provides symmetrical clamping for both positive and negative voltage transients. Unlike unidirectional variants (e.g., MPLAD18KP60AE3), this version has no inherent anode/cathode orientation in circuit placement and protects AC-coupled or floating signal paths equally.
What RoHS compliance level does MPLAD18KP60CAE3 meet?
MPLAD18KP60CAE3 carries the "e3" suffix, indicating full RoHS compliance per Directive 2011/65/EU with matte-tin plating. It satisfies IPC/JEDEC J-STD-020B moisture sensitivity Level 1, requiring no dry-packaging or baking prior to assembly, and supports standard lead-free reflow profiles up to 260 °C for 10 seconds.
