Product details
Overview
MPLAD36KP280AE3/TR from Microchip (formerly Microsemi) is a unidirectional surface-mount transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 280 V working standoff voltage (VWM), 311–345 V breakdown voltage (VBR), and 451 V clamping voltage (VC) at 80 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 MPLAD36KP280AE3/TR datasheet, MPLAD36KP280AE3/TR pinout, MPLAD36KP280AE3/TR application, or MPLAD36KP280AE3/TR equivalent, this device delivers verified high-energy surge handling in a low-profile PLAD package with AEC-Q101 qualification, RoHS compliance (e3), and traceable lot screening - critical for aerospace, automotive load dump, and industrial power rail protection where thermal resistance (RθJC = 1.0 °C/W) and fast response (<100 ps) are mandatory.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transients above its VWM threshold, delivering sub-100 ps response time for unidirectional configurations and sustaining 36 kW pulses without degradation. Its metal-base cathode construction enables direct thermal coupling to heatsinks, supported by RθJC = 1.0 °C/W and RθJA = 50 °C/W on FR4 with recommended pad layout.
It meets IEC 61000-4-2/4-4/4-5 and RTCA DO-160G Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) requirements across multiple protection classes - specifically validated for Level 4/5 pin injection (Waveform 4) and Class 4 secondary lightning (IEC 61000-4-5, 12 Ω source) up to 280 V standoff.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 280 V - Maximum continuous DC or repetitive peak reverse voltage the device blocks without conduction. |
| VBR @ IBR | 311–345 V at 5 mA - Confirmed breakdown range ensures reliable turn-on margin above operating rail. |
| VC @ IPP | 451 V at 80 A - Clamping voltage during 10/1000 μs surge defines maximum stress imposed on protected circuitry. |
| PPP | 36,000 W - Peak pulse power rating validates capability to absorb multi-stroke lightning surges per DO-160. |
| IPP | 80 A - Peak impulse current capacity directly supports IEC 61000-4-5 Class 4 (12 Ω source) compliance. |
| RθJC | 1.0 °C/W - Enables efficient heat transfer to external heatsink, critical for sustained surge duty cycles. |
| Temp Coefficient | 344 mV/°C - Predictable VBR drift with temperature supports stable protection margin over –55 to +150 °C. |
Pinout & Package
The MPLAD36KP280AE3/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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Cathode | Primary current return path and thermal interface - must be soldered to large copper pour or heatsink for RθJC = 1.0 °C/W performance. |
| Top Surface Anode Pad | Anode | Signal-side connection point; polarity marking (band or "K") absent - cathode identification relies solely on metal base orientation. |
Key Features
| Feature | Design Value |
|---|---|
| 36 kW Surge Rating | Validated for multi-stroke lightning per RTCA DO-160 Section 22 - eliminates need for parallel TVS arrays in avionics power inputs. |
| AEC-Q101 Qualification | Ensures reliability under automotive temperature cycling, vibration, and humidity stress - suitable for engine control and ADAS power rails. |
| Low Thermal Resistance | RθJC = 1.0 °C/W enables direct mounting to chassis or heatsink, reducing junction temperature rise by >50% vs. standard SMD TVS. |
| RoHS Compliance (e3) | Meets EU Directive 2011/65/EU with annealed matte-tin plating - compatible with lead-free reflow profiles up to 260 °C. |
| Lot Traceability | Fabrication and assembly lot codes marked on body support failure analysis and supply chain audits for DO-254/DO-178 programs. |
Applications
| Aerospace Power Input Protection | Automotive Load Dump Suppression |
|---|---|
Use Scenario: 28 V aircraft bus input stage subjected to DO-160G Section 22 lightning-induced transients (Waveform 4 & 5A). IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converters to limit voltage excursions to <451 V during 6.4/69 μs and 40/120 μs surges. Use Value: Enables single-device compliance with Level 4/5 pin injection requirements - eliminates cascaded TVS designs and reduces board area by 40%. | Use Scenario: 12 V/24 V vehicle battery line exposed to ISO 7637-2 Pulse 5a (load dump) events up to 120 V. IC Role / Device Role / Timing Role: Unidirectional TVS shunting surge energy to ground before it reaches ECU power management ICs. Use Value: Withstands 36 kW pulses without degradation, maintaining clamping below 451 V even after repeated 80 A surges - extends system MTBF by 3× vs. 5 kW alternatives. |
| Industrial Motor Drive DC Bus | Railway Signaling Interface |
Use Scenario: 300 V DC bus in variable-frequency drives subjected to IGBT switching transients and inductive kickback. IC Role / Device Role / Timing Role: High-energy snubber protecting gate drivers and bus monitors from >1 kV spikes. Use Value: 311–345 V VBR range provides 10% margin above nominal 300 V bus, while 451 V VC prevents latch-up in downstream SiC MOSFET controllers. | Use Scenario: 280 V signaling line in EN 50121-3-2 compliant railway control systems facing EFT bursts and surge coupling. IC Role / Device Role / Timing Role: Secondary protection layer after primary gas discharge tube, clamping residual energy to safe levels. Use Value: Validated for IEC 61000-4-5 Class 4 (12 Ω source) at 280 V - ensures interoperability with legacy signaling infrastructure without redesign. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ280A | Lower PPP (600 W), higher VC (457 V), SMB package with RθJC = 15 °C/W. | Limited to single-stroke surges; unsuitable for DO-160 multi-stroke testing. | Select only for cost-sensitive, low-duty-cycle industrial controls where 36 kW rating is unnecessary. |
| SMCJ280A | Higher PPP (1500 W), same VWM/VC, SMC package with RθJC = 3.5 °C/W. | Cannot meet DO-160 Level 5 or IEC 61000-4-5 Class 4 without derating or parallel devices. | Use when footprint constraints prevent PLAD adoption but thermal performance remains acceptable. |
Compared with SMBJ280A and SMCJ280A, the MPLAD36KP280AE3/TR delivers 24× and 24× higher peak power handling respectively, with 15× and 3.5× lower thermal resistance - enabling single-device compliance in mission-critical avionics and automotive systems where multi-stroke survivability and thermal stability are non-negotiable.

Does the MPLAD36KP280AE3/TR have RoHS compliance?
Yes, the "e3" suffix in MPLAD36KP280AE3/TR explicitly denotes RoHS compliance per EU Directive 2011/65/EU. The device features annealed matte-tin plating on terminals and void-free UL94V-0 epoxy packaging - fully compatible with lead-free reflow soldering processes up to 260 °C for 10 seconds.
What is the thermal resistance from junction to case for the MPLAD36KP280AE3/TR?
The MPLAD36KP280AE3/TR has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W. This low value is achieved via direct metal-base cathode contact to the PCB heatsink pad, enabling efficient heat dissipation during repeated high-energy surges - essential for maintaining reliability in avionics and industrial environments.
How does the MPLAD36KP280AE3/TR support RTCA DO-160G compliance?
The MPLAD36KP280AE3/TR is validated for RTCA DO-160G Section 22 lightning-induced transient testing, specifically Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs).
