Product details
Overview
MPLAD36KP100CAE3 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power systems. It delivers 36 kW peak pulse power at 10/1000 μs, features a 100 V reverse standoff voltage (VWM), clamps to ≤162 V at 223 A peak pulse current (IPP), and operates across –55°C to +150°C junction temperature.
For engineers reviewing the MPLAD36KP100CAE3 datasheet, MPLAD36KP100CAE3 pinout, MPLAD36KP100CAE3 application, or MPLAD36KP100CAE3 equivalent, key selection criteria include IEC 61000-4-5 Class 4/5 secondary lightning compliance, RTCA DO-160F Waveform 4 & 5A pin injection levels, thermal resistance (RθJC = 1.0 °C/W), and RoHS-compliant e3 plating.
Technical Context
This device implements a silicon avalanche diode structure optimized for low clamping ratio and minimal thermal resistance in a void-free thermosetting epoxy PLAD package. Its bidirectional construction enables symmetrical transient suppression on AC lines or differential signal paths without polarity constraints.
It meets AEC-Q101 stress testing requirements and supports MIL-PRF-19500 upscreening options. The metal-base cathode configuration (for unidirectional variants) is adapted to bidirectional symmetry via dual-junction layout, enabling stable multi-stroke operation per RTCA DO-160 Section 22 with <5 ns response time.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | 600 W PPP rating, 5× lower energy handling; DO-214AA package; RθJC = 40 °C/W | Limited to consumer-grade I/O protection; insufficient for DO-160 or AEC-Q101 multi-stroke requirements | Select only for cost-sensitive, low-energy applications where 36 kW capability is unnecessary |
| SMCJ100CA | 1500 W PPP rating; DO-214AB package; RθJC = 10 °C/W; no AEC-Q101 or DO-160 validation | Suitable for industrial PLC I/O but lacks flight-certifiable test documentation and thermal performance | Use when full DO-160 compliance is not required and PCB layout allows larger footprint |
Compared with SMBJ100CA and SMCJ100CA, the MPLAD36KP100CAE3 provides 24× and 24× higher peak pulse power respectively, validated DO-160F and AEC-Q101 qualification, and 1.0 °C/W thermal resistance enabling direct mounting on high-copper PCBs-making it the only option for certified aerospace and high-reliability automotive power rail protection.

FAQ
What is the clamping voltage of MPLAD36KP100CAE3 at its rated peak pulse current?
The MPLAD36KP100CAE3 has a maximum clamping voltage (VC) of 162 V at its specified peak pulse current (IPP) of 223 A under 10/1000 μs waveform conditions. This value is guaranteed across the full operating temperature range and is measured per JEDEC standards. The clamping performance ensures downstream components see no more than 162 V during worst-case surge events, directly supporting design margin calculations for 100 V-rated circuitry.
Does MPLAD36KP100CAE3 meet AEC-Q101 qualification requirements?
Yes, the MPLAD36KP100CAE3 is tested and qualified to AEC-Q101 standards for discrete semiconductors. This includes stress tests for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life. The qualification confirms suitability for automotive powertrain and chassis applications where reliability under extreme environmental conditions is mandatory. Full test reports are available upon request for MPLAD36KP100CAE3.
How does the PLAD package of MPLAD36KP100CAE3 improve thermal performance compared to standard SMC packages?
The PLAD package of MPLAD36KP100CAE3 achieves a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W-over 40× better than typical SMC packages (~40 °C/W). This is accomplished via a void-free transfer-molded epoxy body and direct metal-base thermal interface. As a result, MPLAD36KP100CAE3 can dissipate 36 kW surges with minimal temperature rise, enabling reliable multi-stroke operation without derating in compact layouts.
Is MPLAD36KP100CAE3 suitable for RTCA DO-160 Section 22 lightning protection?
Yes, MPLAD36KP100CAE3 is explicitly validated for RTCA DO-160 Section 22 lightning-induced transient protection. It meets Level 4 and Level 5 requirements for Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) pin injection testing. Data shows sustained performance across ≥1000 multi-stroke events at rated current, making MPLAD36KP100CAE3 appropriate for primary and secondary lightning protection zones in certified aircraft systems.
What is the meaning of the 'CA' and 'E3' suffixes in MPLAD36KP100CAE3?
The 'CA' suffix in MPLAD36KP100CAE3 denotes bidirectional construction, enabling symmetrical clamping for AC or differential signal lines. The 'E3' suffix indicates RoHS-compliant matte-tin plating per JEDEC J-STD-020B Level 1 moisture sensitivity-no dry-pack required and unlimited floor life. Both suffixes are integral to the device's specification and must be included when ordering MPLAD36KP100CAE3 to ensure correct functionality and compliance.
