Product details
Overview
MPLAD36KP58CAE3/TR from Microchip Technology (formerly Microsemi) is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power rails. It delivers 36,000 W peak pulse power at 10/1000 μs, features a 58 V working standoff voltage (VWM), clamps to ≤93.6 V at 385 A peak impulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MPLAD36KP58CAE3/TR datasheet, MPLAD36KP58CAE3/TR pinout, MPLAD36KP58CAE3/TR application, or MPLAD36KP58CAE3/TR equivalent, this device is selected for secondary lightning protection per IEC 61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), pin injection protection per RTCA/DO-160G Waveform 4 (Level 4/5), and ESD/EFT immunity per IEC 61000-4-2/-4.
Technical Context
This bidirectional TVS operates symmetrically across both polarities with matched breakdown voltage (VBR = 64.4–71.2 V at 5 mA) and identical clamping behavior in forward and reverse directions. Its low thermal resistance (RθJC = 1.0 °C/W) enables rapid heat dissipation during repetitive surges, supporting compliance with RTCA DO-160G Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) under temperature-derated conditions.
The PLAD package integrates a metal base acting as the cathode terminal for unidirectional variants and serves as the common reference plane for bidirectional operation. With <5 ns response time and 10 µA maximum standby current at 58 V, it maintains system integrity during fast transients without loading nominal DC rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 36,000 W - Sustains multi-stroke lightning events without degradation |
| Working Standoff Voltage (VWM) | 58 V - Matches nominal 48 V DC systems with 20% margin for ripple and tolerance |
| Clamping Voltage (VC @ IPP) | ≤93.6 V @ 385 A - Limits downstream voltage stress below IC absolute maximum ratings |
| Breakdown Voltage (VBR) | 64.4–71.2 V @ 5 mA - Ensures reliable turn-on before rail overvoltage damages sensitive circuitry |
| Standby Current (ID) | ≤10 µA @ 58 V - Negligible leakage impact on battery-powered or low-power monitoring circuits |
| Response Time | <5 ns - Engages prior to propagation of fast-switching transients (e.g., MOSFET commutation) |
| Operating Temperature Range | –55 °C to +150 °C - Supports under-hood automotive and avionics environments |
Pinout & Package
The MPLAD36KP58CAE3/TR uses the PLAD surface-mount package: a thermosetting epoxy body with void-free molding (UL94V-0), tin-plated terminals, and a metal base serving as the common terminal for bidirectional conduction. The device has two terminals - anode and cathode - marked by polarity indicators on the body; for bidirectional parts, both terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive transient path (bidirectional) | Conducts surge current toward ground or rail during positive or negative excursions |
| Cathode | Negative transient path (bidirectional) | Provides symmetrical return path; metal base enhances thermal coupling to PCB copper pour |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction (CA suffix) | Enables single-device protection of AC-coupled or floating differential lines without polarity constraints |
| AEC-Q101 qualification | Validates reliability for automotive powertrain and chassis applications under temperature cycling and humidity exposure |
| RTCA DO-160G Section 22 compliance | Meets aircraft-level lightning strike survivability for multi-pulse, high-energy transients |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life limitations-supports standard SMT assembly flow |
| 3σ lot norm screening on ID | Guarantees low leakage performance consistency across production lots for critical sensing nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | Lower peak power (600 W), smaller SMB package, higher RθJA (90 °C/W) | Suitable only for low-energy ESD/EFT; cannot meet DO-160G Section 22 or ISO 16750-2 load dump | Select when cost and board space constrain design and surge energy is limited to <100 J |
| SMCJ58CA | Higher peak power (1500 W), SMC package, RθJA = 25 °C/W, no AEC-Q101 or DO-160G validation | Supports basic IEC 61000-4-5 Class 3 but lacks aerospace/automotive qualification traceability | Choose for industrial controls where qualification documentation is not mandated |
Compared with SMBJ58CA and SMCJ58CA, the MPLAD36KP58CAE3/TR provides 24× and 24× higher peak power respectively, validated AEC-Q101 and RTCA DO-160G compliance, and thermal design enabling sustained multi-pulse operation-making it the only option for certified aerospace and 48 V automotive systems.

FAQ
What is the clamping voltage of MPLAD36KP58CAE3/TR at its rated peak pulse current?
The MPLAD36KP58CAE3/TR clamps to a maximum of 93.6 V when subjected to its rated peak impulse current of 385 A under the 10/1000 μs waveform. This value is measured across the device terminals during standardized surge testing and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Is MPLAD36KP58CAE3/TR qualified for automotive applications?
Yes, MPLAD36KP58CAE3/TR is AEC-Q101 qualified, confirming its suitability for automotive powertrain and chassis applications. It undergoes stress testing including temperature cycling, humidity bias, and mechanical shock-validating reliability under harsh vehicle operating conditions such as under-hood environments in 48 V mild hybrid systems.
Does MPLAD36KP58CAE3/TR meet RTCA DO-160G lightning protection requirements?
Yes, MPLAD36KP58CAE3/TR is explicitly validated for RTCA DO-160G Section 22 multi-stroke lightning testing. It supports Waveform 4 (6.4/69 μs) up to Level 5 and Waveform 5A (40/120 μs) up to Level 4, making it appropriate for primary and secondary surge protection in certified avionics equipment.
What is the thermal resistance specification for MPLAD36KP58CAE3/TR?
MPLAD36KP58CAE3/TR has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W and a junction-to-ambient resistance (RθJA) of 50 °C/W when mounted on an FR4 board with 1 oz copper and the recommended pad layout. These values enable effective heat transfer to heatsinks or large copper pours during repetitive surge events.
How does the bidirectional configuration of MPLAD36KP58CAE3/TR affect its circuit implementation?
The CA suffix denotes bidirectional construction, meaning MPLAD36KP58CAE3/TR conducts symmetrically in both polarities-ideal for protecting AC-coupled signal lines, floating buses, or differential pairs without polarity concerns. Unlike unidirectional TVS diodes, it requires no orientation during placement and provides identical clamping in either direction.
