Product details
Overview
MPLAD36KP90CA/TR from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 90 V working standoff voltage (VWM), 100–111 V breakdown voltage (VBR), and 146 V clamping voltage (VC) at 247 A peak impulse current - designed for secondary lightning protection in aircraft avionics per RTCA DO-160G Section 22 Waveform 4 and IEC 61000-4-5.
For engineers reviewing the MPLAD36KP90CA/TR datasheet, MPLAD36KP90CA/TR pinout, MPLAD36KP90CA/TR application, or MPLAD36KP90CA/TR equivalent, this device delivers verified bidirectional surge suppression with <5 ns clamping response, 1.0 °C/W junction-to-case thermal resistance, AEC-Q101 qualification, and Level 1 moisture sensitivity - critical for high-reliability aerospace, automotive load dump, and industrial power rail protection where multi-stroke robustness and low-profile SMT integration are required.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transients above its VWM threshold, with bidirectional symmetry enabling protection against both positive and negative polarity surges without external polarity management. Its PLAD package features a metal base acting as the cathode terminal for unidirectional variants and as the common terminal for bidirectional devices like MPLAD36KP90CA/TR.
Thermal design is enabled by ultra-low RθJC = 1.0 °C/W and RθJA = 50 °C/W (on FR4, 1 oz Cu), supporting high-energy dissipation without heatsink dependency in short-duration events. It meets IEC 61000-4-2/4-4/4-5 and RTCA DO-160G Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) requirements across defined test classes.

FAQ
What is the clamping voltage of MPLAD36KP90CA/TR at its rated peak pulse current?
The MPLAD36KP90CA/TR has a maximum clamping voltage (VC) of 146 V at 247 A peak impulse current (IPP) under the standard 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream circuitry will not experience voltages exceeding 146 V during a full-rated surge event. The clamping performance is validated across temperature and production lots, and is a key parameter used in system-level overvoltage margin analysis for MPLAD36KP90CA/TR deployments.
Is MPLAD36KP90CA/TR suitable for automotive applications requiring AEC-Q101 qualification?
Yes, MPLAD36KP90CA/TR is explicitly AEC-Q101 qualified per the official Microsemi datasheet Revision B. This qualification covers temperature cycling, highly accelerated stress testing, mechanical shock, and humidity resistance - confirming suitability for under-hood and cabin-mounted automotive electronics. The device's 90 V standoff and 146 V clamping align with ISO 7637-2 Pulse 5a/b requirements, and its bidirectional construction supports dual-polarity protection in 12 V/24 V architectures without redesign. MPLAD36KP90CA/TR meets these criteria out-of-the-box with no derating or additional screening required.
How does the PLAD package of MPLAD36KP90CA/TR improve thermal performance compared to standard SMC or SMB packages?
The PLAD package of MPLAD36KP90CA/TR achieves a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W - over 5× lower than typical SMC packages (~60 °C/W) and ~10× lower than SMB packages (~100 °C/W). This is accomplished via a large metal base that serves as both electrical terminal and thermal conduit, enabling direct conduction of surge energy into PCB copper planes or external heatsinks. As a result, MPLAD36KP90CA/TR sustains repeated 36 kW surges without thermal runaway, whereas conventional packages would fail after one or two events. This thermal advantage is documented in Microsemi's derating curves and pad layout recommendations.
Does MPLAD36KP90CA/TR meet RTCA DO-160G Section 22 lightning test requirements?
Yes, MPLAD36KP90CA/TR is specifically characterized and rated for RTCA DO-160G Section 22 Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) lightning-induced transient testing. Per the datasheet, it supports Level 4 (up to 400 V VWM) and Level 5 (up to 300 V VWM) for Waveform 4, and Level 4 (up to 78 V VWM) for Waveform 5A - fully covering the 90 V rating of MPLAD36KP90CA/TR. Its <5 ns response time and 36 kW rating ensure compliance without external circuit modifications, making MPLAD36KP90CA/TR a drop-in solution for certified avionics designs.
What is the moisture sensitivity level (MSL) of MPLAD36KP90CA/TR and how does it affect manufacturing?
MPLAD36KP90CA/TR is rated MSL Level 1 per IPC/JEDEC J-STD-020D.1, meaning it has unlimited floor life and requires no dry-packaging or baking prior to reflow soldering. This eliminates moisture-related popcorning risks and simplifies SMT line logistics - especially important for high-reliability programs with long build cycles or distributed manufacturing. The Level 1 rating is achieved through void-free transfer-molded epoxy encapsulation and is confirmed in the official Microsemi datasheet. No special handling procedures are needed for MPLAD36KP90CA/TR beyond standard RoHS-compliant reflow profiles.
