Product details
Overview
MPLAD36KP64CAE3/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, clamps transients to ≤103.0 V at 350 A, and features a 64 V working standoff voltage (VWM) with ±5% tolerance. Its low thermal resistance (RθJC = 1.0 °C/W) enables robust multi-stroke lightning protection per RTCA DO-160 Section 22.
For engineers reviewing the MPLAD36KP64CAE3/TR datasheet, MPLAD36KP64CAE3/TR pinout, MPLAD36KP64CAE3/TR application, or MPLAD36KP64CAE3/TR equivalent, this device is selected for secondary lightning protection (IEC 61000-4-5), load dump suppression, and pin-injection immunity (DO-160G Waveform 4/5A) where bidirectional clamping, AEC-Q101 qualification, and RoHS-compliant surface-mount reliability are required.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp voltage surges above its 64 V working standoff level, with a guaranteed breakdown voltage range of 71.1–78.6 V at 5 mA test current. Its bidirectional construction (CA suffix) provides symmetrical clamping for AC-coupled or floating bus lines without polarity sensitivity.
Thermal design leverages a metal-base PLAD package with direct junction-to-case conduction path (RθJC = 1.0 °C/W), enabling sustained energy dissipation when mounted on thermally optimized PCB pads. Clamping response time is <5 ns for bidirectional operation, ensuring fast suppression of EFT and ESD transients per IEC 61000-4-2/4-4.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower peak power (600 W), smaller SMB package, higher RθJA (90 °C/W), same 64 V VWM and bidirectional polarity. | Suitable for lower-energy transients (IEC 61000-4-5 Class 2); not rated for DO-160G lightning or automotive load dump. | Select SMBJ64CA only for cost-sensitive consumer electronics where 36 kW capability is unnecessary. |
| SMCJ64CA | Higher peak power (1500 W), larger SMC package, RθJA = 35 °C/W, same VWM/VC specs but lower IPP (100 A). | Supports IEC 61000-4-5 Class 3 with 42 Ω source; insufficient for DO-160G Level 4/5 or AEC-Q101 automotive validation. | Choose SMCJ64CA for industrial controls needing better thermal performance than SMBJ but less than MPLAD36KP64CAE3/TR. |
Compared with SMBJ64CA and SMCJ64CA, the MPLAD36KP64CAE3/TR delivers 24× and 24× higher peak pulse power respectively, validated for aerospace lightning and automotive load dump-making it the sole option among the three qualified to AEC-Q101 and rated for 36 kW surges.

FAQ
What does the "CA" suffix indicate in MPLAD36KP64CAE3/TR?
The "CA" suffix in MPLAD36KP64CAE3/TR denotes bidirectional polarity-meaning the device provides symmetrical clamping for both positive and negative voltage transients. This eliminates polarity concerns during PCB placement and supports protection of AC-coupled or floating bus architectures without requiring separate unidirectional devices on each rail.
Is MPLAD36KP64CAE3/TR qualified for automotive applications?
Yes, MPLAD36KP64CAE3/TR is AEC-Q101 qualified, having passed stress tests including temperature cycling, high-temperature reverse bias, and surge current validation. It is specified for automotive load dump protection per ISO 7637-2 Pulse 5a/b and meets requirements for engine control units, body electronics, and ADAS power domains.
How does the PLAD package improve thermal performance compared to standard SMC or SMB packages?
The PLAD package of MPLAD36KP64CAE3/TR features a metal base that serves as the primary thermal conduction path, achieving RθJC = 1.0 °C/W-over 35× better than SMB packages. This allows efficient heat transfer to the PCB copper pour or heatsink, enabling sustained 36 kW surge handling without thermal runaway during multi-pulse events.
Can MPLAD36KP64CAE3/TR be used for IEC 61000-4-5 compliance testing?
Yes, MPLAD36KP64CAE3/TR is rated for IEC 61000-4-5 secondary lightning protection across Classes 1–4 with 42 Ω source impedance and Class 5 (short distance) with 64 V VWM. Its 350 A IPP and ≤103 V clamping voltage ensure compliance when paired with appropriate upstream filtering and layout practices.
What is the significance of the "TR" suffix in MPLAD36KP64CAE3/TR?
The "TR" suffix in MPLAD36KP64CAE3/TR indicates tape-and-reel packaging per EIA-481-B standard, enabling automated pick-and-place assembly. This format supports high-volume manufacturing with consistent orientation, static-safe handling, and traceable reel-level lot tracking for quality control and audit readiness.
