Product details
Overview
MPLAD36KP160AE3/TR from Microchip Technology (formerly Microsemi) is a unidirectional surface-mount transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 160 V working standoff voltage (VWM), 178–197 V breakdown voltage (VBR), and 259 V clamping voltage (VC) at 139 A peak impulse current - designed for lightning and load dump protection in aerospace power distribution systems.
For engineers reviewing the MPLAD36KP160AE3/TR datasheet, MPLAD36KP160AE3/TR pinout, MPLAD36KP160AE3/TR application, or MPLAD36KP160AE3/TR equivalent, this device delivers verified RTCA DO-160 Section 22 multi-stroke lightning compliance, AEC-Q101 qualification, and IEC 61000-4-5 Class 5 secondary protection up to 160 V standoff - critical for high-reliability avionics and automotive ECU front-end surge suppression.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transients above VWM, with sub-100 ps response time for unidirectional variants and thermal resistance of 1.0 °C/W junction-to-case. It is characterized for 10/1000 μs waveform testing per IEC 61000-4-5 and validated for RTCA DO-160G Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) pin injection.
Designed for surface-mount mounting on FR4 with 1 oz copper, it features void-free thermosetting epoxy packaging (UL94V-0), tin-plated terminals compliant with MIL-STD-750 Method 2026, and moisture sensitivity level 1 - eliminating dry-pack requirements per IPC/JEDEC J-STD-020D.1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V DC maximum continuous standoff - sets minimum system operating voltage threshold before clamping initiates |
| VBR | 178–197 V at 5 mA - defines precise avalanche onset range for predictable turn-on behavior |
| VC | 259 V at 139 A (10/1000 μs) - limits downstream voltage stress during worst-case lightning surge |
| PPP | 36,000 W peak pulse power - enables single-device handling of DO-160 Section 22 multi-stroke events |
| IPP | 139 A peak impulse current - supports Class 5 lightning protection with 42 Ω source impedance |
| RθJC | 1.0 °C/W junction-to-case - allows direct heatsinking via metal base for sustained thermal management |
| TJ | –55 to +150 °C operating range - qualified for extended temperature environments in engine bays and avionics bays |
Pinout & Package
The MPLAD36KP160AE3/TR uses the PLAD surface-mount package: a low-profile, thermally optimized case with exposed metal cathode base (pin 1) and molded epoxy body. Cathode is electrically connected to the metal base; anode is the top-side metallized pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Cathode) | High-current return path | Serves as primary heat sink interface and low-inductance surge current return - must be soldered to large copper pour |
| Top Metallized Pad (Anode) | Transient input node | Connects to protected line (e.g., 28 V aircraft bus); clamps to cathode when VAK exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| 36 kW peak pulse rating | Enables single-device compliance with RTCA DO-160 Section 22 multi-stroke lightning test without parallel staging |
| AEC-Q101 qualification | Validates robustness for automotive powertrain and chassis control modules subject to load dump transients |
| Moisture Sensitivity Level 1 | Eliminates baking requirement prior to reflow - reduces manufacturing cost and avoids thermal stress on components |
| RoHS-compliant (e3) | Meets EU Directive 2011/65/EU and China RoHS II - supports global electronics compliance programs |
| Lot-traceable wafer fabrication | Supports full traceability for aerospace and defense applications requiring AS9102 First Article Inspection |
Applications
| Aerospace Power Distribution | Automotive Engine Control Unit (ECU) |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Lower 600 W PPP, 200 V VC at 32.4 A, SMB package with RθJA = 110 °C/W | Suitable only for single-stroke IEC 61000-4-5 Class 3; insufficient for DO-160 multi-stroke | Select when cost-sensitive consumer-grade designs require basic ESD/EFT protection without lightning compliance |
| SMCJ160A | 1500 W PPP, 259 V VC at 58.2 A, SMC package with RθJC = 2.5 °C/W | Lacks AEC-Q101 and DO-160 certification; limited thermal margin for sustained surge duty cycles | Choose for industrial PLC I/O modules needing higher surge rating than SMBJ but no aerospace qualification |
Compared with SMBJ160A and SMCJ160A, the MPLAD36KP160AE3/TR delivers 24× higher peak power handling, certified multi-stroke lightning resilience, and direct metal-base thermal coupling - making it the only option for mission-critical avionics and high-durability automotive power systems.

FAQ
What is the clamping voltage of MPLAD36KP160AE3/TR at its rated peak pulse current?
The MPLAD36KP160AE3/TR has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak impulse current of 139 A under the standard 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and ensures downstream circuitry remains within safe voltage limits during lightning-level transients. The clamping performance is guaranteed across the full operating temperature range of –55 °C to +150 °C.
Is MPLAD36KP160AE3/TR qualified for automotive applications?
Yes, MPLAD36KP160AE3/TR is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, battery management systems, and ADAS power supplies. Its 160 V working standoff voltage accommodates 24 V heavy-duty vehicle systems and 28 V aircraft buses, while its 36 kW surge rating meets ISO 7637-2 load dump requirements without derating.
Does MPLAD36KP160AE3/TR require dry packing before reflow soldering?
No, MPLAD36KP160AE3/TR has a moisture sensitivity level (MSL) of 1 per IPC/JEDEC J-STD-020D.1, meaning it can be stored indefinitely at ambient conditions and placed directly into reflow without baking. This eliminates process steps, reduces risk of popcorn cracking, and simplifies manufacturing for high-reliability PCB assembly lines.
How is thermal management implemented for MPLAD36KP160AE3/TR?
Thermal management for MPLAD36KP160AE3/TR relies on direct conduction from the silicon die to the exposed metal cathode base, achieving a junction-to-case thermal resistance (RθJC) of 1.0 °C/W. Designers must solder the metal base to a minimum 100 mm² copper pour (1 oz Cu) on FR4, per the recommended pad layout in the datasheet, to maintain junction temperature below 150 °C during repetitive surge events.
Can MPLAD36KP160AE3/TR be used for bidirectional transient suppression?
No - MPLAD36KP160AE3/TR is unidirectional (denoted by "A" suffix). For bidirectional protection, the equivalent part is MPLAD36KP160CAE3/TR ("CA" suffix), which provides symmetrical clamping for AC-coupled or differential signal lines. The unidirectional version is intended for DC power rail protection where polarity is fixed and reverse-voltage blocking is required.
