Product details
Overview
MPLAD36KP60CAE3 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power systems. It delivers 36 kW peak pulse power at 10/1000 μs, clamps at ≤96.8 V under 372 A peak impulse current, and features 60 V reverse standoff voltage (VWM) with ±5% breakdown tolerance (66.7–73.7 V). It meets RTCA DO-160 Section 22 multi-stroke lightning and IEC 61000-4-5 Class 4/5 secondary lightning standards.
For engineers reviewing the MPLAD36KP60CAE3 datasheet, MPLAD36KP60CAE3 pinout, MPLAD36KP60CAE3 application, or MPLAD36KP60CAE3 equivalent, key selection criteria include its bidirectional polarity, low thermal resistance (RθJC = 1.0 °C/W), RoHS-compliant e3 plating, and validated performance under 2 Ω, 12 Ω, and 42 Ω source impedances per IEC 61000-4-5.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, triggering when transient voltage exceeds its breakdown threshold (V(BR)) and diverting surge current to ground. Its void-free UL94V-0 epoxy package and metal-base cathode construction enable efficient heat dissipation during repetitive 36 kW transients.
It supports dual-standard compliance: RTCA DO-160F Waveform 4 (6.4/69 μs) Level 4 up to 400 V standoff, and Waveform 5A (40/120 μs) Level 4 up to 78 V standoff - both confirmed for MPLAD36KP60CAE3 per Microsemi RF01216 Rev B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains aircraft-grade lightning surges without failure |
| Reverse Standoff Voltage (VWM) | 60 V - maximum continuous operating voltage before clamping initiates |
| Breakdown Voltage (V(BR)) | 66.7–73.7 V @ 5 mA - precise conduction threshold enabling predictable overvoltage response |

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. 36,000 W); SMA package; RθJC ≈ 40 °C/W | Only suitable for single-event, low-repetition surges in consumer electronics | Select only if surge energy is <1% of MPLAD36KP60CAE3 capability and thermal mass is limited |
| SMCJ60CA | 1500 W PPP rating; SMC package; RθJC ≈ 10 °C/W; no DO-160 qualification | Applicable for industrial automation but not certified for aviation multi-stroke testing | Choose when cost sensitivity outweighs aerospace compliance and thermal derating margin |
Compared with SMBJ60CA and SMCJ60CA, the MPLAD36KP60CAE3 provides 24× and 24× higher peak power handling respectively, validated thermal performance for repetitive strokes, and formal RTCA DO-160F certification - making it irreplaceable in safety-critical airborne and high-reliability vehicular systems.

FAQ
What is the clamping voltage of the MPLAD36KP60CAE3 at its rated peak pulse current?
The MPLAD36KP60CAE3 has a maximum clamping voltage (VC) of 96.8 V at 372 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is guaranteed across temperature and production lots per Microsemi RF01216 Rev B datasheet, ensuring predictable overvoltage limiting for protected circuits.
Does the MPLAD36KP60CAE3 meet RTCA DO-160 lightning protection requirements?
Yes, the MPLAD36KP60CAE3 is explicitly validated for RTCA DO-160F Section 22 multi-stroke lightning testing. It achieves Level 4 for Waveform 4 (6.4/69 μs) and Level 4 for Waveform 5A (40/120 μs) at 60 V standoff, as documented in Microsemi's RF01216 Rev B specification sheet.
How is thermal management handled in the MPLAD36KP60CAE3 package?
The MPLAD36KP60CAE3 uses a metal-base PLAD package with RθJC = 1.0 °C/W, enabling direct thermal coupling to an external heatsink or large PCB copper pour. Its low junction-to-case resistance allows sustained operation under repetitive 36 kW surges when mounted per the recommended pad layout in RF01216 Rev B.
Is the MPLAD36KP60CAE3 RoHS compliant?
Yes, the "E3" suffix in MPLAD36KP60CAE3 denotes RoHS-compliant matte-tin plating per J-STD-020B Level 1 moisture classification. No dry pack is required, and the device meets lead-free reflow profile requirements up to 260 °C for 10 seconds.
What is the polarity configuration of the MPLAD36KP60CAE3?
The MPLAD36KP60CAE3 is a bidirectional TVS diode, indicated by the "CA" suffix. It conducts symmetrically for both positive and negative transients, with the cathode located on the metal base (bottom side) and the anode on the top surface pad - enabling simplified placement on bidirectional power or signal lines.
