Product details
Overview
MAPLAD36KP15CAE3 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, features a 15 V reverse standoff voltage (VWM), clamps to ≤25.8 V at 1396 A peak pulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP15CAE3 datasheet, MAPLAD36KP15CAE3 pinout, MAPLAD36KP15CAE3 application, or MAPLAD36KP15CAE3 equivalent, this device is selected for secondary lightning protection per IEC 61000-4-5 (42 Ω, 12 Ω, 2 Ω source impedances), pin injection immunity per RTCA/DO-160F Waveform 4 & 5A, and ESD/EFT compliance per IEC 61000-4-2/4-4.
Technical Context
This TVS diode uses an avalanche breakdown mechanism to clamp transients within nanoseconds, with <5 ns response time for bidirectional operation. Its low RθJC of 1.0 °C/W enables efficient heat transfer to the PCB copper pad or heatsink, supporting repetitive surge handling under ≤0.05% duty factor.
It is rated for junction temperatures from –55 °C to +150 °C and complies with AEC-Q101 stress testing. The device's metal-base cathode construction (exposed on package bottom) provides direct thermal path and defines polarity - critical for unidirectional variants, though MAPLAD36KP15CAE3 is bidirectional and symmetric.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains aircraft-grade lightning surges without failure |
| Reverse Standoff Voltage (VWM) | 15 V - maximum continuous operating voltage before clamping initiates |
| Breakdown Voltage (V(BR)) | 15.6–17.2 V @ 5 mA - ensures reliable turn-on margin above VWM |
| Max Clamping Voltage (VC) | 25.8 V @ 1396 A IPP - limits downstream IC voltage stress during worst-case surge |
| Thermal Resistance (RθJC) | 1.0 °C/W - enables effective heat dissipation into PCB copper or heatsink |
| Junction Temperature Range | –55 °C to +150 °C - qualified for extended aerospace and under-hood automotive use |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - no dry pack required; supports standard SMT reflow |
Pinout & Package
MAPLAD36KP15CAE3 uses a surface-mount PLAD package with exposed metal base (cathode for unidirectional versions; symmetric for bidirectional). Dimensions: 12.32 × 10.54 × 5.08 mm (L × W × H), weight ≈ 1.7–2.0 g. Thermal pad must be soldered to ≥1 in² copper area for RθJA = 50 °C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Top Surface Pads (2) | Anode/Cathode terminals (bidirectional) | Electrically symmetric - either pad may connect to line or ground; no polarity marking required |
| Metal Base (Bottom) | Thermal & electrical reference plane | Provides low-inductance return path and primary thermal conduction path to PCB copper |
Key Features

Applications
| Aircraft Avionics Power Input | Automotive DC-DC Converter Input |
|---|---|
Use Scenario: Protection of 28 V DC power inputs in flight control computers subjected to DO-160 Section 22 lightning-induced transients. IC Role / Device Role / Timing Role: Primary secondary surge clamp at board-level input filter stage, placed before upstream EMI filters and DC-DC controllers. Use Value: Limits clamped voltage to ≤25.8 V, preventing latch-up or damage to 36 V-rated input stages of PMICs and microcontrollers. |
Use Scenario: Input protection for 12 V/24 V automotive DC-DC converters exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Fast-response TVS placed directly at connector entry point, shunting energy before transient reaches converter MOSFETs or controllers. Use Value: Withstands 36 kW surges while maintaining <5 ns response, ensuring downstream SiC/GaN FET gate drivers remain within safe operating area. |
| Industrial Ethernet PHY Interface | Renewable Energy Inverter DC Link |
Use Scenario: Common-mode surge suppression on RJ45 magnetics center taps in outdoor industrial switches. IC Role / Device Role / Timing Role: Bidirectional clamp across isolated PHY supply rails, referenced to chassis ground via low-inductance metal base. Use Value: Symmetric clamping prevents rail reversal during fast common-mode events, preserving PHY bias integrity and reducing packet loss. |
Use Scenario: DC link overvoltage protection in solar string inverters subjected to grid-switching transients and lightning coupling. IC Role / Device Role / Timing Role: Parallel-mounted TVS across 600–1000 V DC link capacitors to absorb switching spikes and induced surges. Use Value: 36 kW rating allows single-device protection of high-energy DC links, eliminating need for stacked TVS arrays and reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ15CA | Lower PPP (400 W), smaller SMA package, VC = 24.4 V @ 24.7 A IPP | Suitable only for low-energy IEC 61000-4-2/4-4; not rated for DO-160 or IEC 61000-4-5 Class 5 | Select when cost-sensitive consumer or industrial designs require basic ESD/EFT protection without aerospace or automotive certification. |
| Vishay V26MLA0603NH | MLA varistor, 26 V nominal, 100 J energy rating, slower response (~50 ns), no AEC-Q101 or DO-160 validation | Used in non-safety-critical AC mains or telecom line protection where voltage accuracy and speed are secondary to joule rating | Choose for high-joule, low-cost surge suppression where sub-10 ns response and aviation qualification are not required. |
Compared with SMAJ15CA and V26MLA0603NH, MAPLAD36KP15CAE3 uniquely combines 36 kW pulse power, DO-160F Waveform 4/5A validation, AEC-Q101 qualification, and bidirectional symmetry - making it irreplaceable in certified aerospace and high-reliability automotive power systems.

FAQ
What is the clamping voltage of MAPLAD36KP15CAE3 at its rated peak pulse current?
The MAPLAD36KP15CAE3 has a maximum clamping voltage (VC) of 25.8 V at 1396 A peak pulse current (IPP) 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 circuitry during worst-case transients.
Is MAPLAD36KP15CAE3 qualified for automotive applications?
Yes, MAPLAD36KP15CAE3 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life, temperature cycling, and surge current endurance. It is specified for use in automotive power systems such as DC-DC converter inputs and battery management interfaces where load dump and ISO 7637-2 compliance are required.
Does MAPLAD36KP15CAE3 require special PCB layout considerations?
Yes - MAPLAD36KP15CAE3 requires a minimum 1 in² copper pour beneath its metal base for thermal performance (RθJA = 50 °C/W). The pad layout must follow Microsemi's recommended dimensions (11.94 × 5.85 mm), and traces to the device should be wide and short to minimize inductance and preserve <5 ns response time.
How does MAPLAD36KP15CAE3 differ from unidirectional variants like MAPLAD36KP15AE3?
MAPLAD36KP15CAE3 is bidirectional (denoted by "CA"), providing symmetric clamping for AC signals or floating nodes, whereas MAPLAD36KP15AE3 is unidirectional ("A") with cathode on the metal base. The bidirectional version has identical VWM (15 V) and VC (25.8 V) but lacks polarity marking and supports reverse-voltage surge suppression.
What standards does MAPLAD36KP15CAE3 meet for lightning protection?
MAPLAD36KP15CAE3 meets RTCA DO-160 Section 22 for multi-stroke lightning, IEC 61000-4-5 Class 5 (42 Ω, 12 Ω, and 2 Ω source impedances), and secondary lightning protection requirements across voltage ranges up to 400 V. Its 36 kW rating is validated per Figure 1 in RF01216 Rev B.
