Product details
Overview
MPLAD36KP64CA/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 64 V working standoff voltage (VWM), 71.1–78.6 V breakdown voltage (VBR), and 103.0 V clamping voltage (VC) at 350 A peak impulse current. It is designed for secondary lightning protection in aerospace avionics per RTCA DO-160 Section 22 and IEC 61000-4-5.
For engineers reviewing the MPLAD36KP64CA/TR datasheet, MPLAD36KP64CA/TR pinout, MPLAD36KP64CA/TR application, or MPLAD36KP64CA/TR equivalent, this device delivers verified multi-stroke surge capability, AEC-Q101 qualification, RoHS compliance, and low thermal resistance (RθJC = 1.0 °C/W) in a PLAD package optimized for high-power board-level protection.
Technical Context
This bidirectional TVS operates in avalanche breakdown mode to clamp transients above its VWM threshold, with sub-5 ns response time and <10 µA standby current at 64 V. Its metal-base cathode construction enables direct thermal coupling to heatsinks, supporting sustained power dissipation up to 504 W at TC = 100 °C.
The device meets IEC 61000-4-2 ESD (±30 kV contact), IEC 61000-4-4 EFT (40 A), and IEC 61000-4-5 surge (42 Ω/12 Ω/2 Ω source impedances) across Class 1–5 levels - specifically validated for Level 4/5 pin injection per RTCA/DO-160G Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs).
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) | 64 V DC - blocks normal system operating voltage while remaining fully inactive |
| Clamping Voltage (VC) | 103.0 V at 350 A - limits downstream IC stress to safe levels during worst-case transients |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables efficient heat transfer to external heatsink for repeated surge duty |
| Breakdown Voltage Range (VBR) | 71.1–78.6 V at 5 mA - ensures reliable turn-on margin above VWM with production tolerance |
| Temperature Coefficient (αVBR) | 75 mV/°C - predictable VBR drift over –55 to +150 °C operating range |
| Moisture Sensitivity Level | Level 1 per J-STD-020D.1 - no dry pack required, supports standard SMT reflow |
Pinout & Package
The MPLAD36KP64CA/TR uses the PLAD surface-mount package: void-free thermosetting epoxy body (UL94V-0), metal base acting as cathode terminal, matte-tin plated terminals, and polarity marked by cathode on bottom surface. Weight: ~1.85 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Cathode | Primary current path and thermal interface - must be soldered to large copper pour or heatsink |
| Top Surface (Anode) | Anode | Signal-side connection point - routed to protected line (e.g., CAN bus, sensor input, power rail) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Surge Clamping | Protects AC-coupled or floating lines (e.g., RS-485, Ethernet PHY, antenna feeds) against ± transients |
| AEC-Q101 Qualification | Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock |
| RTCA DO-160G Compliance | Passes Level 4/5 pin injection testing per Waveform 4 and 5A - certified for commercial aircraft systems |
| Low RθJC (1.0 °C/W) | Enables >500 W steady-state power handling when mounted on 2 oz Cu heatsink - critical for multi-stroke events |
| RoHS-compliant & MSL Level 1 | Supports lead-free reflow (260 °C, 10 s) without baking - reduces manufacturing complexity and cost |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower peak power (600 W), higher clamping ratio (VC/VWM = 1.56 vs. 1.61), SMC package | Not suitable for DO-160G Level 4/5 or multi-stroke lightning; limited to consumer/industrial single-event use | Select only for cost-sensitive, non-aerospace designs where 36 kW rating is unnecessary |
| SMCJ64CA | 1500 W peak power, same VWM/VC, larger SMC package, no AEC-Q101 or DO-160G validation | Lacks flight-certified test evidence; requires additional system-level validation for aviation use | Acceptable for automotive ECU front-end if combined with upstream GDT and thermal derating analysis |
Compared with SMBJ64CA and SMCJ64CA, the MPLAD36KP64CA/TR uniquely delivers certified 36 kW multi-stroke capability, AEC-Q101 qualification, and DO-160G Level 5 pin injection performance in a thermally optimized PLAD package - making it irreplaceable for safety-critical aerospace and high-reliability automotive power systems.

FAQ
What is the maximum peak pulse current rating for MPLAD36KP64CA/TR?
The MPLAD36KP64CA/TR is rated for 350 A peak impulse current (IPP) at the standard 10/1000 μs waveform. This value corresponds directly to its 36,000 W peak pulse power rating when clamped at 103.0 V. The device maintains this rating across its full operating temperature range (–55 to +150 °C) with appropriate thermal management, and all units undergo 100% surge testing per datasheet requirements.
Is MPLAD36KP64CA/TR qualified for automotive applications?
Yes, MPLAD36KP64CA/TR is AEC-Q101 qualified, confirming its reliability for automotive under-hood and powertrain applications. It meets stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock. Its 64 V VWM and 103 V VC make it suitable for protecting 12 V/24 V systems against load dump (ISO 7637-2 Pulse 5) and ISO 16750-2 supply voltage variations.
How does the PLAD package of MPLAD36KP64CA/TR improve thermal performance?
The PLAD package features a metal base that serves as both the cathode terminal and primary thermal path. With a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W, MPLAD36KP64CA/TR transfers heat efficiently to PCB copper pours or external heatsinks. This enables sustained power dissipation up to 504 W at 100 °C case temperature - far exceeding standard SMC/SMB packages and essential for multi-stroke surge events.
Does MPLAD36KP64CA/TR meet RTCA DO-160G lightning protection requirements?
Yes, MPLAD36KP64CA/TR is explicitly validated for RTCA DO-160G Section 22 lightning-induced transient susceptibility. It passes Level 4 and Level 5 pin injection testing for Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) at 25 °C. This certification is documented in Microsemi's application notes and supported by lot-level surge test records traceable to wafer fabrication.
What is the polarity configuration indicated by the "CA" suffix in MPLAD36KP64CA/TR?
Per Microsemi's nomenclature, the "CA" suffix in MPLAD36KP64CA/TR denotes bidirectional construction. Unlike unidirectional variants ending in "A", this device clamps transients of either polarity symmetrically - making it ideal for AC-coupled interfaces like RS-485, CAN FD, or antenna feedlines where voltage reversals occur. The cathode is located on the metal base (bottom), and the top surface functions as the anode for both polarities.
