Product details
Overview
MPLAD36KP200AE3 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 36,000 W peak pulse power at 10/1000 μs, features a 200 V reverse standoff voltage (VWM), clamps to ≤322 V at 112 A peak pulse current, and operates across –55°C to +150°C junction temperature. It is qualified to AEC-Q101 and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MPLAD36KP200AE3 datasheet, MPLAD36KP200AE3 pinout, MPLAD36KP200AE3 application, or MPLAD36KP200AE3 equivalent, key selection criteria include its 200 V VWM rating, 322 V max clamping voltage at 112 A, low 1.0 °C/W junction-to-case thermal resistance, RoHS-compliant e3 plating, and qualification for aircraft secondary lightning protection per IEC 61000-4-5 with 42 Ω source impedance (Class 5, short distance).
Technical Context
This TVS diode uses an avalanche breakdown mechanism to divert high-energy transients away from sensitive downstream circuitry. Its metal-base package provides direct thermal path to PCB copper, enabling efficient heat dissipation during repetitive surges up to 0.05% duty factor.
It is specified for unidirectional operation with cathode on the metal base (bottom side), supports steady-state power dissipation of 2.5 W at 25°C ambient, and exhibits a ±10 mV/°C temperature coefficient of breakdown voltage - critical for stable clamping under wide temperature excursions in avionics and engine control units.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A | Lower PPP (400 W), smaller SMA package, higher RθJA (65 °C/W), no AEC-Q101 or DO-160 qualification | Consumer/industrial grade only; unsuitable for aviation or automotive safety-critical systems | Select when cost and board space constrain requirements and regulatory compliance is not required. |
| SMCJ200A | Higher PPP (1500 W), larger SMC package, RθJC ≈ 2.5 °C/W, AEC-Q101 qualified but not DO-160 tested | Automotive-grade only; lacks multi-stroke lightning validation needed for avionics | Choose for automotive ECU protection where DO-160 compliance is unnecessary and 1.5 kW peak power suffices. |
Compared with SMAJ200A and SMCJ200A, the MPLAD36KP200AE3 delivers 24× and 24× higher peak pulse power respectively, integrates DO-160 and AEC-Q101 validation in one device, and provides superior thermal management via metal-base construction - making it the sole option for certified airborne and high-reliability automotive power protection.

FAQ
What is the clamping voltage specification for MPLAD36KP200AE3 under standard test conditions?
The MPLAD36KP200AE3 has a maximum clamping voltage (VC) of 322 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 112 A. This value is measured at 25°C and defines the upper voltage limit imposed on protected circuitry during surge events. The device's low 1.0 °C/W junction-to-case thermal resistance helps maintain this clamping performance across repeated surges in thermally managed layouts.
Is MPLAD36KP200AE3 qualified for automotive applications?
Yes, MPLAD36KP200AE3 is fully qualified to AEC-Q101 for automotive use, including stress testing for temperature cycling, humidity, and mechanical shock. It is specifically intended for load-dump protection in 24 V engine control units and ADAS power domains. Its 200 V VWM rating and 322 V clamping voltage align with ISO 7637-2 Pulse 5a/b requirements, and its RoHS-compliant e3 plating supports modern automotive manufacturing standards.
How does the PLAD package of MPLAD36KP200AE3 improve thermal performance compared to standard SMC or SMA packages?
The PLAD package of MPLAD36KP200AE3 uses a metal base as the cathode terminal, providing a direct thermal conduction path from the silicon die to the PCB copper or external heatsink. With a junction-to-case thermal resistance of just 1.0 °C/W - versus ~2.5 °C/W for SMCJ devices - it sustains higher surge repetition rates without thermal runaway. This architecture is validated for multi-stroke lightning testing per RTCA DO-160 Section 22, where cumulative heating is a key failure mode.
Does MPLAD36KP200AE3 meet RTCA DO-160 lightning protection requirements?
Yes, MPLAD36KP200AE3 is explicitly rated for RTCA DO-160F Section 22 multi-stroke lightning testing. It achieves Level 4 for Pin Injection (Waveform 4, 6.4/69 μs) and Level 4 for Waveform 5A (40/120 μs) at 200 V standoff. Its 36 kW peak pulse rating and metal-base thermal design enable ≥100 pulses at full energy - a requirement for primary and secondary protection in certified aircraft systems such as flight control and navigation units.
What is the polarity configuration and marking convention for MPLAD36KP200AE3?
MPLAD36KP200AE3 is a unidirectional TVS diode, with the cathode located on the metal base (bottom surface) and the anode on the top-side metallized pad. Polarity is indicated by a polarity symbol on the body for unidirectional versions only; the "A" suffix in the part number confirms unidirectional construction. Proper orientation requires the metal base to be soldered to the system ground or low-impedance return path to ensure correct clamping behavior during positive transients.
