Product details
Overview
MPLAD36KP110CA/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 110 V working standoff voltage (VWM), 122–135 V breakdown voltage (VBR), and 177 V clamping voltage (VC) at 204 A peak impulse current (IPP). It delivers lightning and load dump protection in aerospace avionics meeting RTCA DO-160 Section 22.
For engineers reviewing the MPLAD36KP110CA/TR datasheet, MPLAD36KP110CA/TR pinout, MPLAD36KP110CA/TR application, or MPLAD36KP110CA/TR equivalent, key selection criteria include bidirectional polarity, 1.0 °C/W junction-to-case thermal resistance, IEC 61000-4-5 Class 5 compliance (42 Ω source), RTCA/DO-160G Waveform 4 Level 4 capability, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transients above VWM, with sub-5 ns response time for bidirectional variants. Its low RθJC (1.0 °C/W) enables high-power dissipation when mounted on heatsink-equipped PCBs using the metal-base cathode thermal path.
It supports multi-stroke lightning immunity per RTCA DO-160G Section 22 and meets IEC 61000-4-2 ESD (±30 kV contact), IEC 61000-4-4 EFT (40 A), and IEC 61000-4-5 surge (42 Ω, 2 kV–10 kV) standards - validated across full temperature range (–55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 36,000 W at 10/1000 μs waveform - sustains aircraft-level lightning surges without failure |
| Working Standoff Voltage (VWM) | 110 V DC - blocks normal system operating voltage while remaining non-conductive |
| Clamping Voltage (VC) | 177 V at 204 A IPP - limits downstream circuit stress during worst-case transients |
| Breakdown Voltage (VBR) | 122–135 V at 5 mA - defines precise turn-on threshold for predictable clamping onset |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables direct thermal coupling to heatsink for sustained multi-pulse operation |
| Response Time | <5 ns (bidirectional) - ensures protection before sensitive ICs experience overvoltage damage |
| AEC-Q101 Qualified | Yes - certified for automotive powertrain and chassis applications requiring zero defect reliability |
Pinout & Package
Package: PLAD (Plastic Low-profile Anode-down) - void-free UL94V-0 epoxy body with exposed metal cathode base for thermal conduction and mechanical mounting. Cathode is the entire bottom metal surface; anode is top-side metallization.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Metal Base) | High-current return path & thermal interface | Must be soldered to large copper pour or heatsink for RθJC = 1.0 °C/W performance |
| Anode (Top Metallization) | Transient current entry point | Connected to protected line (e.g., 28 V aircraft bus); bidirectional symmetry eliminates polarity concerns |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping on AC lines or ungrounded DC buses without polarity constraints |
| RTCA DO-160G Section 22 compliance | Validated for multi-stroke lightning testing in aircraft systems - critical for FAA/EASA certification |
| IEC 61000-4-5 Class 5 support (42 Ω) | Withstands 10 kV surge with 42 Ω source impedance - meets highest industrial/transportation immunity level |
| MIL-PRF-19500 upscreening option | Enables screening to military reliability standards including lot traceability and extended burn-in |
| Moisture Sensitivity Level 1 | No dry pack or baking required before reflow - reduces manufacturing overhead and handling risk |
Applications
| Aerospace Avionics Bus Protection | Automotive 24 V Load Dump Suppression |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Lower PPP (600 W), higher VC (183 V at 32.4 A), SMC package with RθJC = 10.5 °C/W | Acceptable only for single-event, low-duty-cycle surges; unsuitable for RTCA DO-160 multi-stroke testing | Select SMBJ110CA only for cost-sensitive consumer electronics where 36 kW rating is unnecessary |
| SMCJ110CA | PPP = 1500 W, VC = 187 V at 80.5 A, same PLAD-compatible SMC package but no AEC-Q101 or DO-160 validation | Lacks documented RTCA/DO-160G and AEC-Q101 qualification; limited to industrial-grade applications | Choose SMCJ110CA for non-certified industrial controls where full aerospace/automotive qualification is not mandated |

FAQ
What is the clamping voltage of MPLAD36KP110CA/TR at its rated peak pulse current?
The MPLAD36KP110CA/TR has a maximum clamping voltage (VC) of 177 V when subjected to its rated peak impulse current of 204 A at the 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees downstream circuit protection within safe voltage margins during worst-case transients.
Is MPLAD36KP110CA/TR qualified for automotive applications?
Yes, MPLAD36KP110CA/TR is AEC-Q101 qualified, confirming its suitability for automotive powertrain and chassis applications. It meets stringent requirements for temperature cycling, humidity testing, and surge robustness - validated across –55 °C to +150 °C operating range.
Does MPLAD36KP110CA/TR meet RTCA DO-160G Section 22 lightning standards?
Yes, MPLAD36KP110CA/TR is explicitly designed and tested to meet RTCA DO-160G Section 22 for multi-stroke lightning immunity. Its 36,000 W rating and sub-5 ns response enable compliance with Level 4 and Level 5 pin injection tests using Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs).
What is the thermal resistance from junction to case for MPLAD36KP110CA/TR?
The junction-to-case thermal resistance (RθJC) of MPLAD36KP110CA/TR is 1.0 °C/W. This low value is achieved via direct metal-base cathode contact and requires mounting on a thermally optimized pad layout or heatsink to maintain reliability during repetitive surge events.
How does the bidirectional polarity of MPLAD36KP110CA/TR affect circuit design?
The CA suffix denotes bidirectional construction, meaning MPLAD36KP110CA/TR clamps symmetrically for both positive and negative transients. This eliminates polarity sensitivity in AC-coupled or floating DC systems - simplifying layout and removing risk of reverse installation during assembly.
