Product details
Overview
MPLAD36KP260CA/TR from Microchip (formerly Microsemi) is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power rails. It delivers 36,000 W peak pulse power at 10/1000 μs, clamps transients to ≤419 V at 86 A peak impulse current, and features a 260 V working standoff voltage with <5 ns response time - enabling compliance with RTCA DO-160 Section 22 lightning testing and IEC 61000-4-5 Class 3/4 secondary protection.
For engineers reviewing the MPLAD36KP260CA/TR datasheet, MPLAD36KP260CA/TR pinout, MPLAD36KP260CA/TR application, or MPLAD36KP260CA/TR equivalent, key selection criteria include its bidirectional polarity, low thermal resistance (RθJC = 1.0 °C/W), AEC-Q101 qualification, RoHS-compliant e3 marking, and suitability for long-distance pin injection protection per RTCA/DO-160G Waveform 4 Level 5.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp overvoltage transients before they damage downstream circuitry. Its PLAD package integrates a metal base acting as the cathode terminal, enabling direct thermal coupling to PCB copper for efficient heat dissipation during multi-stroke surges.
Designed for systems requiring robust immunity to lightning-induced surges and load dump events, it supports both unidirectional and bidirectional configurations - with the "CA" suffix confirming bidirectional construction. The device meets IEC 61000-4-2 ESD (±30 kV contact), IEC 61000-4-4 EFT (4 kV), and IEC 61000-4-5 surge (up to 4 kV with 42 Ω source impedance).
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 transients without cascading devices. |
| Working Standoff Voltage (VWM) | 260 V DC - matches nominal 230–277 VAC line-derived DC bus voltages in industrial power supplies and avionics converters. |
| Clamping Voltage (VC) | 419 V at 86 A IPP - limits voltage stress on 600 V MOSFETs and IGBTs during surge events. |
| Breakdown Voltage (VBR) | 289–320 V at 5 mA - ensures reliable conduction onset above normal operating voltage with margin for tolerance and temperature drift. |
| Response Time | <5 ns (bidirectional) - fast enough to protect sensitive gate drivers and analog front-ends from sub-microsecond transients. |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - allows sustained energy absorption when mounted on ≥1 oz Cu thermal pad, critical for multi-pulse DO-160 testing. |
| Temperature Coefficient (αVBR) | 318 mV/°C - quantifies voltage shift across –55°C to +150°C operating range, essential for derating in high-ambient environments. |
Pinout & Package
The MPLAD36KP260CA/TR uses the PLAD surface-mount package: a low-profile, void-free thermosetting epoxy body (UL94V-0) with a metal base serving as the cathode terminal. The anode is accessed via the top-side metallized pad. Total weight is ~1.8 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Cathode | Primary thermal path to PCB; must be soldered to large copper pour for RθJC = 1.0 °C/W performance. |
| Top Metallized Pad | Anode | Electrical connection point; requires standard SMT reflow profile compatible with 260 °C peak solder temperature. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional surge suppression | Protects AC-coupled or floating signal/power lines without polarity sensitivity - ideal for Ethernet PHY interfaces and sensor bridges. |
| AEC-Q101 qualification | Validated for automotive under-hood applications including engine control modules and battery management systems. |
| RTCA DO-160G Section 22 compliance | Passes multi-stroke lightning test (Waveform 4 Level 5, long distance) - required for commercial aircraft avionics certification. |
| Moisture Sensitivity Level 1 | No dry pack or baking required prior to reflow - reduces manufacturing overhead and eliminates moisture-related popcorning risk. |
| Traceable wafer and assembly lots | Enables full lot-level failure analysis and reliability tracking for mission-critical aerospace deployments. |
Applications
| Aerospace Power Distribution | Automotive DC-DC Converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ260CA | Lower peak power rating (600 W), smaller SMB package, higher RθJA (110 °C/W), no AEC-Q101 or DO-160 qualification. | Suitable only for low-energy board-level ESD/EFT; cannot meet DO-160G Section 22 or IEC 61000-4-5 Class 4/5. | Select when cost and board space constrain requirements, and surge energy remains below 100 J. |
| SMCJ260CA | Higher peak power (1500 W), larger SMC package, RθJA = 35 °C/W, AEC-Q101 qualified but not DO-160G tested. | Meets IEC 61000-4-5 Class 3 with 42 Ω source, but insufficient for multi-stroke lightning or long-distance pin injection. | Choose for automotive body electronics where DO-160G is not required and thermal budget allows moderate derating. |
Compared with SMBJ260CA and SMCJ260CA, the MPLAD36KP260CA/TR delivers 24× and 24× higher peak pulse power respectively, enables certified aircraft deployment via DO-160G compliance, and provides 1.0 °C/W thermal resistance for sustained multi-pulse operation - making it the only option for high-reliability aerospace and heavy-duty industrial surge protection.

FAQ
What is the maximum clamping voltage of the MPLAD36KP260CA/TR at its rated peak pulse current?
The MPLAD36KP260CA/TR has a maximum clamping voltage (VC) of 419 V when subjected to its rated peak pulse current (IPP) of 86 A under the 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and ensures downstream components like 600 V power semiconductors remain within safe operating limits during surge events. The MPLAD36KP260CA/TR maintains this clamping performance across its full operating temperature range of –55°C to +150°C.
Is the MPLAD36KP260CA/TR suitable for RTCA DO-160G Section 22 lightning testing?
Yes, the MPLAD36KP260CA/TR is explicitly rated for RTCA DO-160G Section 22 multi-stroke lightning testing, including Waveform 4 (6.4/69 μs) Level 5 long-distance pin injection. Its 36,000 W peak pulse power rating, <5 ns response time, and validated thermal design enable repeatable performance across multiple strokes without parameter shift or failure. The MPLAD36KP260CA/TR is one of few surface-mount TVS diodes qualified for this stringent aerospace requirement.
Does the MPLAD36KP260CA/TR require special handling due to moisture sensitivity?
No, the MPLAD36KP260CA/TR is rated Moisture Sensitivity Level 1 (MSL-1) per IPC/JEDEC J-STD-020D.1, meaning it can be stored indefinitely at ambient conditions without dry packing or baking prior to reflow soldering. This eliminates moisture-related risks such as popcorning during assembly and simplifies logistics for high-reliability manufacturing. The MPLAD36KP260CA/TR's void-free epoxy encapsulation contributes to this robust MSL rating.
How does the thermal performance of the MPLAD36KP260CA/TR compare to standard SMC/SMB TVS diodes?
The MPLAD36KP260CA/TR achieves a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W - over 30× lower than typical SMCJ-class devices (~35 °C/W) and >100× lower than SMBJ-class parts (~110 °C/W). This is enabled by its metal-base PLAD package, which transfers heat directly to the PCB copper. As a result, the MPLAD36KP260CA/TR sustains higher energy absorption over multiple pulses without thermal runaway, a critical advantage in DO-160G testing and industrial drive applications.
What is the significance of the "CA" suffix in MPLAD36KP260CA/TR?
Per Microchip's nomenclature (Table 1, Datasheet Revision B), the "CA" suffix in MPLAD36KP260CA/TR denotes bidirectional polarity - meaning the device functions identically for positive and negative transients, with symmetrical clamping behavior around 0 V. This differs from unidirectional variants (e.g., MPLAD36KP260A) that conduct only in reverse bias. The "TR" suffix indicates tape-and-reel packaging per EIA-481-B, supporting automated SMT placement. The MPLAD36KP260CA/TR thus provides polarity-agnostic protection ideal for AC-coupled or floating circuits.
