Product details
Overview
MAPLAD18KP130CA from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) rated for 18,000 W peak pulse power at 10/1000 μs, with 130 V reverse standoff voltage (VWM), 144–159 V breakdown voltage (V(BR)), and 209 V maximum clamping voltage (VC) at 100 A IPP. It delivers RTCA DO-160F Level 5 pin injection protection and meets IEC 61000-4-5 Class 1–5 secondary lightning protection requirements for aerospace and automotive systems.
For engineers reviewing the MAPLAD18KP130CA datasheet, MAPLAD18KP130CA pinout, MAPLAD18KP130CA application, or MAPLAD18KP130CA equivalent, key selection criteria include its bidirectional polarity, 130 V VWM rating, 209 V clamping performance at 100 A, thermal resistance of 0.7 °C/W junction-to-case, and qualification to AEC-Q101 and MIL-PRF-19500 screening standards.
Technical Context
The MAPLAD18KP130CA is a high-reliability, plastic-encapsulated TVS diode designed for multi-stroke lightning surge suppression in harsh environments. Its void-free UL94V-0 epoxy case and metal-base cathode construction enable low thermal resistance (RθJC = 0.7 °C/W) and efficient heat dissipation during repetitive transients.
It operates as a bidirectional clamp with symmetrical breakdown behavior, supporting both positive and negative surge events without polarity constraints. The device is surge-tested per IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and RTCA DO-160F Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs), with temperature derating guidance provided in MicroNote 132 and 134.

FAQ
What is the clamping voltage of MAPLAD18KP130CA at its rated peak pulse current?
The MAPLAD18KP130CA has a maximum clamping voltage (VC) of 209 V at 100 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is measured per standard test methods and represents the upper limit of voltage imposed on protected circuitry during a full-rated surge event. The MAPLAD18KP130CA maintains this clamping performance across its qualified temperature range and is validated for multi-stroke operation in RTCA DO-160-compliant designs.
Is MAPLAD18KP130CA qualified for automotive applications?
Yes, MAPLAD18KP130CA is qualified to AEC-Q101 for automotive use, including under-hood engine control unit (ECU) applications subject to load dump and ISO 7637-2 transients. Its bidirectional construction, 130 V VWM rating, and 209 V clamping voltage align with 12 V system protection requirements. The MAPLAD18KP130CA also supports optional MIL-PRF-19500 upscreening for mission-critical automotive programs requiring enhanced lot traceability and screening.
Does MAPLAD18KP130CA meet RTCA DO-160 lightning protection requirements?
Yes, MAPLAD18KP130CA is explicitly rated for RTCA DO-160F Section 22 multi-stroke lightning protection, including Level 5 pin injection immunity for Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs). Its 18,000 W peak pulse power rating and low RθJC (0.7 °C/W) enable compliance with the cumulative heating requirements of aircraft design standards. The MAPLAD18KP130CA is listed in the RF01215 datasheet as qualified for Level 5 up to 130 V VWM variants.
What is the thermal resistance and how does it impact PCB layout for MAPLAD18KP130CA?
The MAPLAD18KP130CA has a junction-to-case thermal resistance (RθJC) of 0.7 °C/W, achieved via its metal-base construction. This requires direct thermal coupling to a large copper pour or heatsink on the PCB bottom side. Layout must follow the recommended pad dimensions (12.32–12.57 mm × 10.54–10.80 mm) and avoid solder mask over the metal base. The MAPLAD18KP130CA's low RθJC enables sustained multi-pulse operation without thermal runaway-critical for DO-160 Section 22 testing.
How does the bidirectional construction of MAPLAD18KP130CA affect its use in DC circuits?
The bidirectional construction of MAPLAD18KP130CA allows symmetrical clamping of both positive and negative transients without polarity constraints, making it ideal for protecting DC rails where reverse voltage events (e.g., load dump reversal, inductive kickback) may occur. Unlike unidirectional TVS devices, the MAPLAD18KP130CA does not require orientation verification during placement and eliminates risk of incorrect installation. Its 130 V VWM applies equally across both polarities, simplifying design for dual-threat environments.
