Product details
Overview
MPLAD36KP200A from Microsemi is a unidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace and automotive power systems. It delivers 36 kW peak pulse power at 10/1000 μs, clamps at ≤322 V under 10 A peak pulse current, and features a 200 V reverse standoff voltage (VWM) with 222–245 V breakdown range (V(BR)). Its low-profile thermoset epoxy package enables robust lightning protection per RTCA DO-160 Section 22 and secondary IEC 61000-4-5 compliance.
For engineers reviewing the MPLAD36KP200A datasheet, MPLAD36KP200A pinout, MPLAD36KP200A application, or MPLAD36KP200A equivalent, key selection criteria include its 200 V VWM rating, 322 V max clamping voltage at IPP, thermal resistance of 1.0 °C/W junction-to-case, RoHS-compliant matte-tin plating, and qualification to AEC-Q101 for automotive reliability.
Technical Context
This TVS diode operates as a clamping device in DC power rail protection, activated when transient voltage exceeds its 200 V standoff threshold. Its silicon avalanche structure provides sub-100 ps response time and handles multi-stroke lightning events per RTCA DO-160F Waveform 4 (6.4/69 μs) up to Level 5 for short-distance configurations.
Designed for surface-mount assembly on FR4 PCBs with specified pad layout, it achieves 50 °C/W junction-to-ambient thermal resistance when mounted per recommended footprint. Steady-state dissipation is limited to 2.5 W at 25°C ambient, derating linearly above 25°C per Figure 3.
Key Specifications

FAQ
What is the maximum clamping voltage of MPLAD36KP200A at its rated peak pulse current?
The MPLAD36KP200A has a maximum clamping voltage (VC) of 322 V when subjected to its rated peak pulse current of 10 A under 10/1000 μs waveform conditions. This value is measured per Figure 3 in the RF01216 Rev B datasheet and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance remains stable across its full operating temperature range of –55°C to +150°C.
Is MPLAD36KP200A qualified for automotive applications?
Yes, MPLAD36KP200A is tested and qualified to AEC-Q101 standards for discrete semiconductors, confirming its suitability for automotive underhood environments. It withstands temperature cycling, humidity testing, and mechanical shock per the specification. Its 200 V VWM and 322 V clamping voltage make it appropriate for protecting 12 V and 24 V battery-fed systems against load dump and ISO 7637-2 transients.
Does MPLAD36KP200A require dry packing for moisture sensitivity?
No, MPLAD36KP200A is rated Moisture Sensitivity Level 1 (MSL-1) per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions without dry packing or baking prior to reflow soldering. This eliminates handling complexity and reduces manufacturing risk in high-volume SMT lines.
How does the PLAD package of MPLAD36KP200A improve thermal performance?
The PLAD package of MPLAD36KP200A features a metal base cathode that serves as both electrical return and primary thermal path. With a junction-to-case thermal resistance of just 1.0 °C/W, it transfers heat directly to PCB copper pours or external heatsinks far more efficiently than standard SMD packages like DO-214AB (RθJC ≈ 15 °C/W) or DO-214AA (RθJC ≈ 35 °C/W), enabling sustained high-power surge handling.
Can MPLAD36KP200A be used for RTCA DO-160F lightning protection?
Yes, MPLAD36KP200A is validated for RTCA DO-160F Section 22 lightning-induced transient protection. Specifically, it meets Pin Injection Protection Level 5 for Waveform 4 (6.4/69 μs) in short-distance configurations, as confirmed in the RF01216 Rev B datasheet. Its 36 kW PPP rating and fast response ensure compliance with multi-stroke lightning standards required for commercial aircraft systems.
