Product details
Overview
MPLAD36KP200CAE3 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace and automotive 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 meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MPLAD36KP200CAE3 datasheet, MPLAD36KP200CAE3 pinout, MPLAD36KP200CAE3 application, or MPLAD36KP200CAE3 equivalent, key selection criteria include bidirectional polarity, IEC 61000-4-5 Class 4/5 secondary lightning compliance with 12 Ω and 42 Ω source impedances, RTCA/DO-160F Waveform 4 Level 4 capability, and RoHS-compliant e3 termination plating.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered by avalanche breakdown above its specified V(BR) range of 222–245 V. Its low thermal resistance (RθJC = 1.0 °C/W) enables rapid heat dissipation during repetitive surges, supporting duty factors ≤0.05% per test conditions.
It is rated for junction temperatures from –55 °C to +150 °C and exhibits a temperature coefficient of breakdown voltage (αV(BR)) of +243 mV/°C. The device uses a void-free UL94V-0 epoxy package with tin-plated terminals compliant with MIL-STD-750 Method 2026.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains aircraft-grade lightning transients without failure |
| Reverse Standoff Voltage (VWM) | 200 V - maximum continuous operating voltage before clamping initiates |
| Breakdown Voltage (V(BR)) | 222–245 V @ 5 mA - precise avalanche threshold enabling predictable turn-on |
| Max Clamping Voltage (VC) | 322 V @ 112 A - limits downstream circuit voltage stress during surge events |
| Peak Pulse Current (IPP) | 112 A @ 10/1000 μs - quantifies maximum surge current handled at rated PPP |
| Thermal Resistance (RθJC) | 1.0 °C/W - ensures efficient heat transfer to heatsink or PCB copper for reliability |
| Standby Current (ID) | 10 μA @ 200 V - negligible leakage during normal operation, preserving system efficiency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | 600 W PPP rating, 5.0 mm × 4.5 mm SMB package, RθJC ≈ 35 °C/W | Limited to single-stroke surges; not qualified for RTCA DO-160F Waveform 4 or IEC 61000-4-5 Class 4/5 | Select when cost-sensitive industrial designs require basic ESD/EFT protection without aerospace certification. |
| SMCJ200CA | 1500 W PPP rating, 7.2 mm × 6.2 mm SMC package, RθJC ≈ 15 °C/W | Supports higher repetition rates than SMBJ but lacks DO-160F validation and fails Class 4/5 42 Ω testing at 200 V standoff | Choose for automotive body electronics where AEC-Q101 is required but full DO-160F compliance is unnecessary. |
Compared with SMBJ200CA and SMCJ200CA, the MPLAD36KP200CAE3 provides 24× and 24× higher peak pulse power respectively, validated clamping performance under aviation lightning standards, and superior thermal management-making it irreplaceable in certified airborne systems.

FAQ
What is the clamping voltage of MPLAD36KP200CAE3 at its rated peak pulse current?
The MPLAD36KP200CAE3 has a maximum clamping voltage (VC) of 322 V at 112 A peak pulse current 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 circuits during worst-case transients.
Does MPLAD36KP200CAE3 meet RTCA DO-160F lightning protection requirements?
Yes, the MPLAD36KP200CAE3 is validated for RTCA DO-160F Section 22 multi-stroke lightning testing, including Waveform 4 (6.4/69 μs) Level 4 compliance. Its bidirectional design and 36 kW rating enable sustained performance across repeated strokes without degradation, satisfying FAA airworthiness mandates for commercial avionics.
What is the thermal resistance specification for MPLAD36KP200CAE3, and why does it matter?
The MPLAD36KP200CAE3 has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W. This low value allows efficient heat transfer from the silicon die to the PCB copper or external heatsink, preventing thermal runaway during repetitive surge events and extending operational lifetime in high-duty-cycle applications like aircraft power buses.
How does the CA suffix in MPLAD36KP200CAE3 affect its circuit implementation?
The CA suffix indicates bidirectional construction, meaning the MPLAD36KP200CAE3 conducts and clamps symmetrically for both positive and negative voltage transients. Unlike unidirectional variants, it requires no polarity-aware placement and can protect AC-coupled lines, floating sensors, or differential buses without additional diodes or layout constraints.
Is MPLAD36KP200CAE3 compatible with lead-free reflow processes?
Yes, the MPLAD36KP200CAE3 carries the e3 RoHS-compliant marking and features annealed matte-tin plating qualified for standard lead-free reflow profiles up to 260 °C for 10 seconds. Its UL94V-0 epoxy body remains stable during JEDEC J-STD-020-compliant thermal cycling, eliminating moisture sensitivity concerns.
