Product details
Overview
MPLAD36KP260AE3/TR from Microsemi is a surface-mount unidirectional 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 - designed for secondary lightning protection in avionics per RTCA DO-160 Section 22 and IEC 61000-4-5.
For engineers reviewing the MPLAD36KP260AE3/TR datasheet, MPLAD36KP260AE3/TR pinout, MPLAD36KP260AE3/TR application, or MPLAD36KP260AE3/TR equivalent, key selection criteria include verified clamping performance under 2 Ω/12 Ω/42 Ω source impedances, AEC-Q101 qualification, RoHS-compliant matte-tin plating, and thermal resistance of 1.0 °C/W junction-to-case - critical for high-reliability aerospace and automotive load dump circuits.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient overvoltages on DC power rails and signal lines. Its low RθJC = 1.0 °C/W enables effective heat transfer to an external heatsink, supporting repeated surge events without thermal runaway.
It delivers 419 V clamping at 86 A (10/1000 μs), with <100 ps response time for unidirectional operation, and meets IEC 61000-4-2 ESD (±30 kV contact), IEC 61000-4-4 EFT (4 kV), and RTCA DO-160G Waveform 4 & 5A pin injection requirements up to Level 5 depending on standoff voltage selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 260 V - maximum continuous DC or repetitive peak reverse voltage the device blocks without conduction |
| VBR @ IBR | 289–320 V at 5 mA - guaranteed avalanche initiation range, defining minimum overvoltage threshold |
| VC @ IPP | 419 V at 86 A (10/1000 μs) - maximum voltage seen by protected circuit during worst-case surge |
| PPP | 36,000 W - peak pulse power handling capacity, enabling robust multi-stroke lightning protection |
| RθJC | 1.0 °C/W - low thermal resistance from junction to case, allowing direct mounting to heatsink for sustained surge duty |
| ID @ VWM | ≤10 µA - ultra-low leakage ensures minimal standby power loss in high-impedance monitoring circuits |
| αV(BR) | 318 mV/°C - temperature coefficient used to calculate VBR derating above 25 °C ambient |
Pinout & Package
The MPLAD36KP260AE3/TR uses the PLAD surface-mount package: void-free UL94V-0 epoxy body with metal base acting as cathode terminal; total weight ≈1.7–2.0 g; RoHS-compliant matte-tin plating on terminals; polarity marked by cathode on bottom metal surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (top surface pad) | Transient current entry point | Connected to line/rail requiring protection; current flows into anode during positive transients |
| Cathode (metal base) | Transient current return path & thermal interface | Must be soldered to large copper pour or heatsink; serves dual role as electrical return and primary thermal conduction path |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ260A | Lower 600 W PPP rating; SMB package; RθJC = 35 °C/W; no AEC-Q101 or DO-160 qualification | Restricted to low-energy consumer electronics; unsuitable for multi-stroke lightning or automotive load dump | Select only for cost-sensitive, non-safety-critical 260 V rail protection where single-event surges ≤100 A are expected |
| SMCJ260A | 1500 W PPP; SMC package; RθJC = 15 °C/W; AEC-Q101 qualified but not DO-160 tested | Limited to automotive infotainment or body electronics; cannot meet RTCA DO-160 Section 22 multi-stroke requirement | Choose when needing AEC-Q101 compliance at lower cost, but verify system-level lightning testing with external crowbar or GDT staging |
Compared with SMBJ260A and SMCJ260A, the MPLAD36KP260AE3/TR delivers 24× and 24× higher peak power handling respectively, with certified DO-160G compliance and 1.0 °C/W thermal resistance - making it the only option for avionics-grade 260 V bus protection requiring repeatable 36 kW surge absorption.

FAQ
What is the clamping voltage of MPLAD36KP260AE3/TR at its rated peak pulse current?
The MPLAD36KP260AE3/TR has a maximum clamping voltage (VC) of 419 V at 86 A peak impulse current with a 10/1000 μs waveform. This value is measured under standardized surge conditions and defines the upper voltage limit imposed on the protected circuit during worst-case transients. It is confirmed in Table 4 of the official datasheet Revision B and applies directly to the MPLAD36KP260AE3/TR under 25 °C ambient conditions.
Is MPLAD36KP260AE3/TR qualified for automotive applications?
Yes, the MPLAD36KP260AE3/TR is AEC-Q101 qualified, validating its suitability for automotive powertrain and chassis applications. It meets stress tests including high-temperature operating life, temperature cycling, and surge immunity relevant to 12 V/24 V load dump events per ISO 7637-2. This qualification is explicitly stated in Section 1.1 of the datasheet and applies to the exact MPLAD36KP260AE3/TR part number.
Does MPLAD36KP260AE3/TR require dry packing before reflow soldering?
No, the MPLAD36KP260AE3/TR has IPC/JEDEC J-STD-020D.1 moisture sensitivity level (MSL) 1, meaning it is not moisture-sensitive and does not require dry packing, baking, or floor-life controls prior to reflow. This is confirmed in Section 1.1 of the datasheet and reduces manufacturing complexity for high-volume assembly of the MPLAD36KP260AE3/TR.
What is the thermal resistance from junction to case for MPLAD36KP260AE3/TR?
The MPLAD36KP260AE3/TR has a thermal resistance of RθJC = 1.0 °C/W, as specified in Table 3 (Absolute Maximum Ratings). This low value reflects the metal-base construction of the PLAD package and enables efficient heat transfer to an external heatsink - a critical parameter for sustaining repeated 36 kW surges. This specification is measured and guaranteed for the MPLAD36KP260AE3/TR.
Can MPLAD36KP260AE3/TR be used for bidirectional transient suppression?
No, the MPLAD36KP260AE3/TR is a unidirectional TVS, indicated by the "A" suffix (not "CA"). It conducts only during reverse-biased overvoltage events and must be oriented with cathode to ground. For bidirectional protection at 260 V standoff, the correct part is MPLAD36KP260CAE3/TR - the "CA" variant is a separate device with different breakdown symmetry and clamping behavior.
