Product details
Overview
MPLAD36KP100CA 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 impulse current (IPP), and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MPLAD36KP100CA datasheet, MPLAD36KP100CA pinout, MPLAD36KP100CA application, or MPLAD36KP100CA equivalent, this device is selected for secondary lightning protection per IEC 61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), RTCA DO-160F Waveform 4 & 5A pin injection compliance, and high-reliability AEC-Q101 qualified surge suppression in space-constrained SMT layouts.
Technical Context
This TVS diode uses silicon avalanche technology with low thermal resistance (RθJC = 1.0 °C/W) and a void-free UL94V-0 epoxy package optimized for rapid heat dissipation under multi-stroke transients. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal/power lines without polarity concerns.
It meets stringent aerospace requirements including RTCA DO-160 Section 22 multi-stroke lightning immunity and supports MIL-PRF-19500 upscreening options. Standby leakage (ID ≤10 μA @ VWM) and tight breakdown voltage tolerance (111–123 V @ 5 mA) ensure stable operation in high-impedance monitoring circuits.
Key Specifications

FAQ
What is the clamping voltage of the MPLAD36KP100CA at its rated peak pulse current?
The MPLAD36KP100CA has a maximum clamping voltage (VC) of 162 V at its rated peak pulse current (IPP) of 223 A under 10/1000 μs waveform conditions. This value is measured per JEDEC standards and ensures downstream circuitry remains within safe voltage limits during worst-case surge events. The MPLAD36KP100CA maintains this performance across its full operating temperature range.
Is the MPLAD36KP100CA qualified for automotive applications?
Yes, the MPLAD36KP100CA is AEC-Q101 qualified for automotive applications, including engine control units and battery management systems. It undergoes wafer fabrication and assembly lot traceability, 3σ standby current screening, and surge testing per AEC-Q101 requirements. The MPLAD36KP100CA also supports optional MIL-PRF-19500 upscreening for extended reliability needs.
How does the PLAD package of the MPLAD36KP100CA improve thermal performance?
The MPLAD package of the MPLAD36KP100CA features an exposed metal cathode base that serves as the primary thermal interface, achieving a low junction-to-case thermal resistance of 1.0 °C/W. When mounted on a recommended FR4 pad layout with thermal vias, it minimizes cumulative heating during multi-stroke transients. This design directly supports sustained operation under RTCA DO-160 Section 22 test profiles.
Does the MPLAD36KP100CA meet IEC 61000-4-5 for lightning surge immunity?
Yes, the MPLAD36KP100CA is validated for IEC 61000-4-5 secondary lightning protection across multiple source impedances: Class 1–5 at 42 Ω, Class 1–4 at 12 Ω, and Class 2–4 at 2 Ω. Its 100 V VWM and 111–123 V V(BR) range ensure compatibility with 100 V system architectures while maintaining margin for voltage overshoot. The MPLAD36KP100CA data sheet specifies exact class coverage per impedance.
What is the moisture sensitivity level (MSL) of the MPLAD36KP100CA?
The MPLAD36KP100CA is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and requires no dry pack or baking prior to reflow soldering. This eliminates handling constraints in high-volume SMT production and ensures consistent assembly yield. The MPLAD36KP100CA's void-free UL94V-0 epoxy body contributes to this robust MSL rating.
