Product details
Overview
MPLAD36KP17CA/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 17 V working standoff voltage (VWM), 18.9–20.9 V breakdown voltage (VBR), and 28.8 V clamping voltage (VC) at 1250 A peak impulse current. It delivers lightning and load dump protection in aerospace avionics meeting RTCA DO-160 Section 22.
For engineers reviewing the MPLAD36KP17CA/TR datasheet, MPLAD36KP17CA/TR pinout, MPLAD36KP17CA/TR application, or MPLAD36KP17CA/TR equivalent, this device is selected for high-energy surge suppression where low thermal resistance (RθJC = 1.0 °C/W), fast response (<5 ns for bidirectional), and AEC-Q101 qualification are required in compact surface-mount designs.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient overvoltages across protected lines. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal/power rails without polarity dependency.
Designed for multi-stroke lightning compliance per RTCA DO-160G Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs), it supports Level 4 and Level 5 pin injection protection up to 300 V standoff. Thermal performance is optimized via metal-base cathode attachment and low RθJC, enabling direct heatsink mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 36,000 W at 10/1000 μs - sustains aircraft-grade lightning surges without failure |
| Working Standoff Voltage (VWM) | 17 V - maximum continuous DC or peak reverse voltage before conduction begins |
| Clamping Voltage (VC) | 28.8 V at IPP = 1250 A - limits downstream voltage stress during worst-case transients |
| Breakdown Voltage (VBR) | 18.9–20.9 V at IBR = 5 mA - defines precise turn-on threshold for reliable triggering |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables high-power dissipation with minimal temperature rise when mounted to heatsink |
| Response Time | <5 ns (bidirectional) - ensures sub-nanosecond reaction to fast-rising ESD/EFT events |
| AEC-Q101 Qualified | Yes - validated for automotive under-hood and powertrain applications requiring reliability certification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17CA | Lower peak power (600 W), smaller SMB package, higher RθJA (65 °C/W) | Suitable for consumer electronics with lower surge severity; not DO-160G Level 5 compliant | Select only for cost-sensitive, non-aerospace applications with <1 kA surge exposure |
| SMCJ17CA | Higher peak power (1500 W), larger SMC package, RθJC = 2.5 °C/W, no AEC-Q101 qualification | Applicable in industrial controls but lacks aviation certification and thermal performance for sustained multi-stroke events | Use where DO-160G compliance is unnecessary and board space allows larger footprint |

FAQ
What is the clamping voltage of MPLAD36KP17CA/TR at its rated peak pulse current?
The MPLAD36KP17CA/TR has a maximum clamping voltage (VC) of 28.8 V when subjected to its rated peak pulse current of 1250 A at the 10/1000 μs waveform. This value is measured per standard test conditions in the datasheet and ensures downstream circuitry remains within safe operating voltage limits during high-energy transients.
Is MPLAD36KP17CA/TR qualified for automotive applications?
Yes, MPLAD36KP17CA/TR is AEC-Q101 qualified, confirming its suitability for automotive powertrain and chassis applications exposed to harsh electrical environments such as load dump and ISO 7637-2 transients. Its thermal and surge performance meets requirements for under-hood deployment when properly heatsinked.
How does the PLAD package of MPLAD36KP17CA/TR improve thermal performance?
The PLAD package features a metal base cathode that serves as both the electrical return path and primary thermal interface. With a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W, MPLAD36KP17CA/TR efficiently transfers transient energy heat to an external heatsink or copper pour, preventing thermal runaway during repetitive surges.
What standards does MPLAD36KP17CA/TR meet for lightning protection?
MPLAD36KP17CA/TR meets RTCA DO-160G Section 22 for multi-stroke lightning, including Waveform 4 (6.4/69 μs) Level 4 and Level 5, and Waveform 5A (40/120 μs) Level 4 up to 300 V standoff. It also supports secondary lightning protection per IEC 61000-4-5 with 42 Ω, 12 Ω, and 2 Ω source impedances.
Does MPLAD36KP17CA/TR require special handling due to moisture sensitivity?
No - MPLAD36KP17CA/TR has IPC/JEDEC J-STD-020D.1 Moisture Sensitivity Level 1, meaning it can be stored indefinitely at ambient conditions without dry packing or baking prior to reflow. This simplifies manufacturing logistics and eliminates floor-life constraints during SMT assembly.
