Product details
Overview
MPLAD36KP260CAE3/TR from Microsemi (now Microchip) is a bidirectional surface-mount transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 260 V working standoff voltage (VWM), 289–320 V breakdown voltage (VBR), and 419 V clamping voltage (VC) at 86 A peak impulse current (IPP). It is AEC-Q101 qualified and designed for secondary lightning protection in aerospace avionics per RTCA DO-160G Section 22.
For engineers reviewing the MPLAD36KP260CAE3/TR datasheet, MPLAD36KP260CAE3/TR pinout, MPLAD36KP260CAE3/TR application, or MPLAD36KP260CAE3/TR equivalent, this device is selected for high-energy surge suppression in DC bus lines of aircraft power systems, automotive load dump circuits, and industrial DC distribution where low thermal resistance (RθJC = 1.0 °C/W) and fast response (<5 ns clamping delay) are critical.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection against bipolar transients without polarity-sensitive placement. Its PLAD package features a metal base acting as the cathode terminal for unidirectional variants - but for MPLAD36KP260CAE3/TR, the metal base serves as the common reference point for dual-anode/dual-cathode configuration.
It delivers 36 kW surge capability under standardized 10/1000 μs waveform while maintaining VC ≤ 419 V at IPP = 86 A, and supports IEC 61000-4-5 Class 3–5 lightning protection with 2 Ω, 12 Ω, and 42 Ω source impedances. Standby leakage (ID) is ≤10 µA at 260 V, ensuring minimal system loading during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 260 V - Maximum continuous DC or repetitive peak voltage the device blocks without conduction. |
| VBR | 289–320 V at 5 mA - Confirmed breakdown threshold range; ensures reliable triggering above operating bus voltage. |
| VC | 419 V at 86 A (10/1000 μs) - Clamped voltage seen by protected circuit during worst-case surge event. |
| IPP | 86 A - Peak non-repetitive surge current the device safely shunts without degradation. |
| RθJC | 1.0 °C/W - Enables direct heatsinking to PCB copper or external metal; critical for thermal management in high-duty-cycle surges. |
| TJ Range | –55 to +150 °C - Validated junction temperature range supporting operation in engine bay or avionics bay environments. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronic components including HTOL, TCT, and ESD. |
Pinout & Package
The MPLAD36KP260CAE3/TR uses the PLAD surface-mount package: a low-profile, void-free transfer-molded thermosetting epoxy body (UL94V-0) with a metal base acting as the common terminal. Cathode/anode terminals are formed on the metal base underside; for bidirectional construction, both sides of the metal base serve symmetrical conduction paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Common Conduction Terminal | Serves as shared anode/cathode node for bidirectional operation; requires full-surface solder pad for thermal and electrical integrity. |
| Top Surface Pads | Isolated Signal Interfaces | No functional top-side terminals - all conduction occurs through metal base; top surface is insulated epoxy. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Surge Suppression | Protects AC-coupled or floating DC lines without polarity orientation constraints during board assembly. |
| 36 kW Peak Pulse Power | Handles multi-stroke lightning events per RTCA DO-160G Section 22 without parametric shift or failure. |
| RθJC = 1.0 °C/W | Enables >90% of surge energy to be conducted directly into PCB copper or heatsink, minimizing junction temperature rise. |
| AEC-Q101 Qualification | Validates reliability for automotive powertrain and chassis modules exposed to vibration, thermal cycling, and humidity. |
| RoHS-compliant (e3) | Meets EU Directive 2011/65/EU; matte-tin plating ensures solderability and long-term intermetallic stability. |

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 vs. 36,000 W); SMA package; RθJC ≈ 40 °C/W. | Suitable for low-energy ESD/IEC 61000-4-2; not rated for DO-160G lightning or load dump. | Select SMBJ260CA only for cost-sensitive consumer-grade designs with <100 A surge exposure. |
| SMCJ260CA | Higher power (1500 W) than SMBJ but still 24× lower than MPLAD36KP260CAE3/TR; SMC package; RθJC ≈ 15 °C/W. | Valid for IEC 61000-4-5 Class 3 with 42 Ω source; insufficient for DO-160G Level 5 or automotive load dump. | Choose SMCJ260CA when footprint and thermal budget allow larger SMC, but 36 kW capability is unnecessary. |
Compared with SMBJ260CA and SMCJ260CA, the MPLAD36KP260CAE3/TR provides 24× and 24× higher surge power handling respectively, enables direct metal-base heatsinking (RθJC = 1.0 °C/W), and is the only one qualified to RTCA DO-160G Section 22 and AEC-Q101 for mission-critical deployment.

FAQ
What is the clamping voltage of MPLAD36KP260CAE3/TR at its rated peak pulse current?
The MPLAD36KP260CAE3/TR has a maximum clamping voltage (VC) of 419 V when subjected to its rated 86 A peak impulse current (IPP) under the standard 10/1000 μs waveform. This value is measured across the metal base terminals and defines the upper voltage limit imposed on protected circuitry during surge events. The MPLAD36KP260CAE3/TR maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is MPLAD36KP260CAE3/TR suitable for automotive applications?
Yes, the MPLAD36KP260CAE3/TR is AEC-Q101 qualified and explicitly rated for automotive load dump protection per ISO 7637-2 Pulse 5a. Its 36,000 W surge rating, 260 V working standoff, and 419 V clamping voltage enable robust protection of 24 V and 48 V battery-connected systems. The device's RθJC = 1.0 °C/W allows effective thermal coupling to chassis ground or heatsink, making MPLAD36KP260CAE3/TR appropriate for powertrain and ADAS control units.
How does the PLAD package of MPLAD36KP260CAE3/TR differ from standard SMC or SMB packages?
The PLAD package used by MPLAD36KP260CAE3/TR features a large metal base that serves as the primary conduction and thermal path - unlike SMC/SMB packages where leads carry current and dissipate heat. This design achieves RθJC = 1.0 °C/W (vs. ~15–40 °C/W for SMC/SMB), enabling direct PCB copper or heatsink mounting. The MPLAD36KP260CAE3/TR has no top-side pins; conduction occurs exclusively through the soldered metal base, requiring specific pad layout per Figure 7 in the datasheet.
Does MPLAD36KP260CAE3/TR meet RTCA DO-160G lightning protection requirements?
Yes, the MPLAD36KP260CAE3/TR is validated for RTCA DO-160G Section 22 lightning-induced transient testing, including Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs). At 260 V standoff, it satisfies Level 5 for Waveform 4 and Level 4 for Waveform 5A. Its 36 kW rating and <5 ns response time ensure compliance without additional external components - a key requirement for MPLAD36KP260CAE3/TR in certified aircraft electronics.
What is the standby leakage current specification for MPLAD36KP260CAE3/TR at rated VWM?
The MPLAD36KP260CAE3/TR exhibits a maximum standby leakage current (ID) of 10 µA when biased at its rated 260 V working standoff voltage (VWM) and tested at 25 °C. This low leakage ensures minimal power loss and signal interference in always-on systems such as avionics bus monitors or automotive telematics modules. The MPLAD36KP260CAE3/TR maintains ID ≤ 50 µA across its full –55 °C to +150 °C operating range.
