Product details
Overview
MPLAD36KP15CA/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 15 V working standoff voltage (VWM), 16.7–18.5 V breakdown voltage (VBR), and 25.8 V clamping voltage (VC) at 1396 A peak impulse current - designed for secondary lightning protection in avionics per RTCA DO-160 Section 22 and IEC 61000-4-5.
For engineers reviewing the MPLAD36KP15CA/TR datasheet, MPLAD36KP15CA/TR pinout, MPLAD36KP15CA/TR application, or MPLAD36KP15CA/TR equivalent, key selection criteria include bidirectional polarity, low thermal resistance (RθJC = 1.0 °C/W), AEC-Q101 qualification, RoHS compliance, and IEC 61000-4-2/4-4/4-5 compliance for ESD, EFT, and surge immunity in harsh industrial and aerospace environments.
Technical Context
This device operates as a voltage-clamped crowbar during transients, leveraging silicon avalanche diode structure to clamp voltages within nanoseconds (<5 ns response for bidirectional units). Its PLAD package features a metal base acting as cathode terminal, enabling direct thermal coupling to heatsinks and supporting high-reliability operation from –55 °C to +150 °C junction temperature.
It delivers stable clamping performance across multi-stroke events per RTCA DO-160G Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs), with full surge testing per IEC standards and 3σ lot norm screening on standby current (ID ≤ 750 µA at VWM). Moisture sensitivity level is IPC/JEDEC J-STD-020D.1 Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 36,000 W at 10/1000 μs - enables single-device protection against severe lightning-induced surges without cascaded stages |
| Working Standoff Voltage | 15 V - matches nominal 12 V automotive and avionics bus systems while allowing margin above peak operating voltage |
| Clamping Voltage | 25.8 V at 1396 A - limits downstream IC stress below 28 V absolute maximum ratings of common power management ICs |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - supports high-power dissipation with minimal temperature rise when mounted on copper heatsink pads |
| Response Time | <5 ns (bidirectional) - ensures sub-cycle clamping before sensitive analog or digital circuitry sustains damage |
| Standby Current | ≤750 µA at 15 V - avoids measurable leakage impact on low-power sleep modes in battery-backed systems |
| Temperature Range | –55 °C to +150 °C - qualified for engine bay, flight control, and industrial outdoor deployments |
Pinout & Package
The MPLAD36KP15CA/TR uses the PLAD surface-mount package: a low-profile, void-free thermosetting epoxy body (UL94V-0) with metal base cathode and matte-tin-plated terminals. Weight is ~1.8 g. Cathode is the entire metal bottom surface; anode is the top-side metallized pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Cathode | Primary heat path and return path for surge current; must be soldered to large copper thermal pad for RθJC = 1.0 °C/W performance |
| Top Metallized Pad | Anode | Input connection point for protected line; layout requires symmetric trace routing to minimize inductance and preserve <5 ns response |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Protects AC-coupled or floating lines (e.g., RS-485, CAN, sensor bridges) without polarity dependency |
| AEC-Q101 qualification | Validated for automotive powertrain and chassis applications including load dump and jump-start conditions |
| RTCA DO-160G Section 22 compliance | Meets multi-stroke lightning test requirements for aircraft equipment up to Level 5 (Waveform 4 & 5A) |
| Moisture Sensitivity Level 1 | Eliminates baking requirement prior to reflow, reducing manufacturing cost and handling risk |
| Full lot surge testing | Every production lot verified to withstand 36 kW pulses - ensures field reliability without sampling uncertainty |
Applications
| Aerospace Avionics Power Bus | Automotive Engine Control Unit (ECU) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Lower peak power (600 W), smaller SMB package, higher RθJA (65 °C/W), no AEC-Q101 or DO-160G validation | Suitable only for board-level ESD/EFT; cannot meet 36 kW lightning or load dump requirements | Select SMBJ15CA only for cost-sensitive consumer electronics where surge energy is limited to <100 J |
| SMCJ15CA | 1500 W peak power, SMC package, RθJC = 2.5 °C/W, AEC-Q101 qualified but not DO-160G tested | Acceptable for automotive infotainment, but insufficient for engine bay or avionics multi-stroke testing | Choose SMCJ15CA when thermal budget allows higher junction rise and certification scope excludes aviation standards |
Compared with SMBJ15CA and SMCJ15CA, the MPLAD36KP15CA/TR provides 24× and 24× higher peak power respectively, validated clamping performance under multi-stroke lightning, and a thermally optimized PLAD package enabling sustained surge handling in mission-critical systems.

FAQ
What is the clamping voltage of MPLAD36KP15CA/TR at its rated peak pulse current?
The MPLAD36KP15CA/TR has a maximum clamping voltage (VC) of 25.8 V when subjected to its rated peak impulse current of 1396 A at the 10/1000 μs waveform. This value is measured per standard test conditions in the datasheet and ensures downstream 28 V-rated components remain within safe operating limits during surge events.
Is MPLAD36KP15CA/TR qualified for automotive applications?
Yes, MPLAD36KP15CA/TR is AEC-Q101 qualified and validated for automotive use cases including 12 V load dump protection. Its bidirectional construction, 15 V standoff, and 25.8 V clamping make it suitable for protecting ECUs, body control modules, and ADAS power inputs against ISO 7637-2 and IEC 61000-4-5 transients.
Does MPLAD36KP15CA/TR require moisture preconditioning before reflow soldering?
No - MPLAD36KP15CA/TR is rated IPC/JEDEC J-STD-020D.1 Moisture Sensitivity Level 1, meaning it may be stored and processed at ambient conditions without baking or dry pack. This eliminates handling steps and reduces risk of popcorning during lead-free reflow.
How does the PLAD package of MPLAD36KP15CA/TR improve thermal performance?
The PLAD package uses a metal base as the cathode terminal, providing a direct low-resistance thermal path from junction to PCB copper. With RθJC = 1.0 °C/W, MPLAD36KP15CA/TR achieves significantly lower junction temperature rise than SMB/SMC packages during repeated 36 kW surges - critical for multi-stroke reliability in avionics.
Can MPLAD36KP15CA/TR be used for IEC 61000-4-5 testing with 2 Ω source impedance?
Yes - MPLAD36KP15CA/TR is rated for IEC 61000-4-5 Class 4 protection with 2 Ω source impedance (per datasheet Table 4 notes), supporting peak currents up to 1396 A. Its 25.8 V clamping voltage ensures protected circuits remain functional even under this demanding short-circuit surge condition.
