Product details
Overview
MPLAD36KP130AE3/TR from Microsemi (now Microchip) is a unidirectional surface-mount transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 130 V working standoff voltage (VWM), 144–159 V breakdown voltage (VBR), and 209 V clamping voltage (VC) at 173 A peak impulse current - designed for lightning and load dump protection in aerospace avionics per RTCA DO-160 Section 22.
For engineers reviewing the MPLAD36KP130AE3/TR datasheet, MPLAD36KP130AE3/TR pinout, MPLAD36KP130AE3/TR application, or MPLAD36KP130AE3/TR equivalent, key selection criteria include verified IEC 61000-4-5 Class 4 compliance (2 Ω source), DO-160G Waveform 4 & 5A pin injection levels, thermal resistance (RθJC = 1.0 °C/W), RoHS-compliant matte-tin plating, and PLAD package mechanical compatibility with FR4 PCB layouts.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient overvoltages above its VWM threshold, delivering sub-100 ps response time for unidirectional devices. Its low RθJC (1.0 °C/W) enables high-energy dissipation without thermal runaway when mounted on heatsinked copper pads.
It meets AEC-Q101 qualification and supports multi-stroke lightning immunity per RTCA DO-160G Section 22, with validated performance under 2 Ω, 12 Ω, and 42 Ω source impedances per IEC 61000-4-5. Standby leakage (ID ≤ 10 µA at 130 V) ensures minimal system power loss during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous DC or repetitive peak reverse voltage before conduction begins; sets minimum system operating margin. |
| VBR | 144–159 V at 5 mA - Confirmed breakdown range defines reliable turn-on threshold under surge conditions. |
| VC | 209 V at 173 A (10/1000 μs) - Clamped voltage seen by protected circuit during worst-case surge; determines downstream component stress. |
| PPP | 36,000 W - Peak pulse power handling capacity at standard 10/1000 μs waveform; validates suitability for aircraft load dump events. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance enables direct heatsink mounting for sustained energy absorption without derating. |
| IPP | 173 A - Maximum non-repetitive peak impulse current; defines single-event surge capability per IEC 61000-4-5. |
| αV(BR) | 157 mV/°C - Temperature coefficient of breakdown voltage; used to calculate VBR shift across –55°C to +150°C operating range. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Lower peak power (600 W), smaller SMB package, higher RθJA (65 °C/W), no AEC-Q101 or DO-160 qualification. | Only suitable for consumer-grade 130 V line protection; cannot meet aviation or automotive surge standards. | Select only for cost-sensitive, low-energy applications where 36 kW rating is unnecessary. |
| SMCJ130A | 1500 W peak power, SMC package, RθJC = 2.5 °C/W, qualified to AEC-Q101 but not DO-160. | Acceptable for automotive ECU protection but fails RTCA DO-160G Section 22 multi-stroke validation. | Choose when DO-160 compliance is not required and board space allows larger SMC footprint. |
Compared with SMBJ130A and SMCJ130A, the MPLAD36KP130AE3/TR delivers 24× and 24× higher peak power respectively, with certified DO-160G and AEC-Q101 qualifications, making it the sole option for safety-critical aerospace and high-end automotive systems requiring validated 36 kW surge handling.

FAQ
What is the clamping voltage of MPLAD36KP130AE3/TR at its rated peak pulse current?
The MPLAD36KP130AE3/TR has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak impulse current of 173 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream components remain within safe operating voltage margins.
Is MPLAD36KP130AE3/TR qualified for automotive applications?
Yes, the MPLAD36KP130AE3/TR is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, battery management systems, and ADAS power supplies. It withstands temperature cycling, mechanical shock, and humidity exposure per AEC-Q101 stress tests - enabling deployment in under-hood and chassis-mounted electronics where load dump and switching transients occur.
Does MPLAD36KP130AE3/TR meet RTCA DO-160G Section 22 lightning requirements?
Yes, the MPLAD36KP130AE3/TR is explicitly validated for RTCA DO-160G Section 22 multi-stroke lightning testing, supporting Waveform 4 (6.4/69 μs) up to Level 5 and Waveform 5A (40/120 μs) up to Level 4. Its 36,000 W rating, low RθJC, and fast response (<100 ps) enable compliance without supplemental protection - a requirement for FAA-certified avionics hardware.
What is the thermal resistance specification for MPLAD36KP130AE3/TR?
The MPLAD36KP130AE3/TR has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W, measured with the cathode metal base thermally bonded to a heatsink or large copper plane. This low value allows efficient heat transfer during high-energy transients, preventing thermal runaway and enabling repeated surge handling - essential for systems exposed to frequent lightning-induced events.
How does the PLAD package of MPLAD36KP130AE3/TR differ from standard SMC or SMB TVS packages?
The PLAD package of MPLAD36KP130AE3/TR features a metal-base construction that serves as both cathode terminal and primary thermal path, unlike plastic-bodied SMC/SMB packages. With dimensions of 10.3 × 8.4 × 3.2 mm and void-free UL94V-0 epoxy, it achieves 1.0 °C/W RθJC - over 2× better than SMCJ130A - and supports direct heatsink mounting for sustained 36 kW surge dissipation.
