Product details
Overview
MPLAD36KP130CAE3 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 kW peak pulse power at 10/1000 μs, clamps transients to ≤209 V at 173 A, and features a 130 V reverse standoff voltage (VWM), 144–159 V breakdown voltage (V(BR)), and 1.0 °C/W junction-to-case thermal resistance - enabling robust secondary lightning protection per IEC 61000-4-5 and RTCA DO-160F Waveform 4 Level 4.
For engineers reviewing the MPLAD36KP130CAE3 datasheet, MPLAD36KP130CAE3 pinout, MPLAD36KP130CAE3 application, or MPLAD36KP130CAE3 equivalent, key selection criteria include its bidirectional polarity, 130 V VWM rating, 209 V max clamping voltage at 173 A, RoHS-compliant e3 plating, and qualification to AEC-Q101 and MIL-PRF-19500 screening levels.
Technical Context
This device operates as a silicon avalanche diode-based TVS, leveraging controlled breakdown behavior to shunt high-current transients away from sensitive circuitry. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal lines, and its low RθJC of 1.0 °C/W supports reliable thermal dissipation when mounted on FR4 with recommended pad layout.
The MPLAD36KP130CAE3 meets stringent multi-stroke lightning standards including RTCA DO-160F Section 22 (Waveform 4, Level 4) and IEC 61000-4-5 with 42 Ω, 12 Ω, and 2 Ω source impedances - specifically rated for Class 4 protection at 2 Ω impedance per specification table. Standby current is screened to 3σ lot norm at ≤10 μA @ VWM.

FAQ
What is the clamping voltage of the MPLAD36KP130CAE3 at its rated peak pulse current?
The MPLAD36KP130CAE3 has a maximum clamping voltage (VC) of 209 V at its peak pulse current (IPP) of 173 A under 10/1000 μs waveform conditions. This value is measured per standard test methods and ensures downstream circuitry remains below critical overvoltage thresholds during surge events. The MPLAD36KP130CAE3 achieves this while maintaining bidirectional symmetry and low thermal resistance.
Is the MPLAD36KP130CAE3 qualified for automotive applications?
Yes, the MPLAD36KP130CAE3 is qualified to AEC-Q101 for automotive applications. It undergoes stress testing across -55°C to +150°C, including temperature cycling, highly accelerated life testing, and surge validation per load dump and ISO 7637-2 requirements. Its qualification supports use in engine control units, battery management systems, and other under-hood electronics where reliability under extreme thermal and electrical stress is mandatory. The MPLAD36KP130CAE3 also supports optional MIL-PRF-19500 upscreening.
Does the MPLAD36KP130CAE3 meet RTCA DO-160F lightning protection requirements?
Yes, the MPLAD36KP130CAE3 is explicitly rated for RTCA DO-160F Section 22 lightning-induced transient susceptibility testing. It meets Waveform 4 (6.4/69 μs) Level 4 for 130 V-rated devices and is validated for multi-stroke endurance. The device's low clamping voltage, high PPP, and thermal design enable compliance without derating in typical avionics mounting configurations. Documentation confirms MPLAD36KP130CAE3 inclusion in the DO-160F-certified part list for 130 V bidirectional variants.
What is the thermal resistance profile of the MPLAD36KP130CAE3?
The MPLAD36KP130CAE3 has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W and a junction-to-ambient resistance (RθJA) of 50 °C/W when mounted on FR4 with the recommended pad layout. This low RθJC enables efficient heat transfer from the silicon die through the metal base into the PCB copper, supporting repeated high-energy surges without thermal runaway. The MPLAD36KP130CAE3's thermal design is integral to its 36 kW rating and DO-160F multi-stroke capability.
How does the bidirectional construction of the MPLAD36KP130CAE3 affect its circuit implementation?
The bidirectional construction of the MPLAD36KP130CAE3 eliminates polarity sensitivity, allowing direct placement across AC-coupled lines, differential data buses, or ungrounded power rails without orientation constraints. Its symmetric V-I characteristics ensure identical clamping in both directions, simplifying layout and avoiding reverse-connection failures. This makes the MPLAD36KP130CAE3 ideal for protecting isolated interfaces like RS-485, CAN FD, or avionics ARINC 429 receivers where signal polarity may vary or be undefined.
