Product details
Overview
MPLAD36KP260CAE3 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, clamps transients to ≤419 V at 86 A, and features a 260 V reverse standoff voltage (VWM), 289–320 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 5.
For engineers reviewing the MPLAD36KP260CAE3 datasheet, MPLAD36KP260CAE3 pinout, MPLAD36KP260CAE3 application, or MPLAD36KP260CAE3 equivalent, key selection criteria include its bidirectional polarity, RoHS-compliant e3 plating, 260 V VWM rating for 220–260 V DC bus protection, and validated performance under multi-stroke lightning stress with <5 ns response time.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating when transient voltage exceeds its breakdown threshold. Its void-free UL94V-0 epoxy package and metal-base cathode construction minimize thermal resistance, supporting sustained energy dissipation without thermal runaway under repetitive surges at ≤0.05% duty factor.
It meets AEC-Q101 reliability standards and supports MIL-PRF-19500 upscreening options. The device is characterized for IEC 61000-4-2/4-4/4-5, RTCA DO-160F Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs), with derating applied per MicroNote 132 and 134 for temperature and steady-state power叠加.

FAQ
What is the clamping voltage of MPLAD36KP260CAE3 at its rated peak pulse current?
The MPLAD36KP260CAE3 has a maximum clamping voltage (VC) of 419 V at 86 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is guaranteed across temperature and ensures downstream components remain within safe voltage margins during standardized lightning surge events. The MPLAD36KP260CAE3 achieves this with low dynamic impedance and optimized silicon geometry.
Is MPLAD36KP260CAE3 certified for RTCA DO-160F lightning testing?
Yes, the MPLAD36KP260CAE3 is validated for RTCA DO-160F Section 22 lightning-induced transient testing, including Waveform 4 (6.4/69 μs) Level 5 up to 260 V VWM devices. Its 36,000 W PPP rating and sub-5 ns response enable compliance with multi-stroke requirements. The MPLAD36KP260CAE3 documentation explicitly lists this qualification in Rev B of RF01216.
Does MPLAD36KP260CAE3 require dry pack packaging per J-STD-020?
No, the MPLAD36KP260CAE3 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it does not require dry pack packaging or floor life limitations before reflow soldering. This simplifies manufacturing logistics and eliminates bake-out steps. The MPLAD36KP260CAE3's void-free epoxy body contributes to this robust MSL rating.
What is the thermal resistance from junction to case for MPLAD36KP260CAE3?
The MPLAD36KP260CAE3 has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W, measured with the case temperature controlled on a heatsink as specified. This low value enables efficient heat transfer to external thermal mass, supporting repeated surge events without thermal runaway. The MPLAD36KP260CAE3's metal-base construction directly facilitates this performance.
Can MPLAD36KP260CAE3 be used in automotive applications?
Yes, the MPLAD36KP260CAE3 is AEC-Q101 qualified and rated for -55°C to +150°C operating temperature, making it suitable for automotive 48 V mild hybrid systems, battery disconnect units, and ADAS power domains. Its bidirectional capability protects against both load dump and reverse battery transients. The MPLAD36KP260CAE3 meets stringent automotive reliability and surge immunity requirements.
