Product details
Overview
MPLAD36KP100AE3 from Microsemi is a unidirectional 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, clamps at ≤162 V under 223 A peak impulse current, and features a 100 V reverse standoff voltage (VWM), 111–123 V breakdown voltage (V(BR)), and 1.0 °C/W junction-to-case thermal resistance.
For engineers reviewing the MPLAD36KP100AE3 datasheet, MPLAD36KP100AE3 pinout, MPLAD36KP100AE3 application, or MPLAD36KP100AE3 equivalent, key selection criteria include its DO-160F Waveform 4/5A compliance, IEC 61000-4-5 Class 4/5 secondary lightning protection capability with 42 Ω/12 Ω source impedance, and RoHS-compliant e3 matte-tin plating suitable for lead-free reflow.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating above its 100 V standoff threshold to divert surge energy away from sensitive components. Its low RθJC (1.0 °C/W) enables effective heat transfer to a heatsink or PCB copper plane, supporting multi-stroke surge endurance per RTCA DO-160 Section 22.
The MPLAD36KP100AE3 uses a silicon avalanche structure optimized for fast response (<100 ps rise time), stable clamping under repetitive transients (≤0.05% duty factor), and robust ESD/EFT immunity per IEC 61000-4-2/4-4. Its unidirectional polarity places the cathode on the metal base for direct thermal coupling to the PCB ground plane.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Lower PPP (600 W), SMA package, RθJA = 110 °C/W, no DO-160F certification | Suitable only for consumer-grade or non-safety-critical single-stroke surges | Select when cost and board space constrain design, and aviation/rail certifications are not required. |
| SMCJ100A | Higher PPP (1500 W), SMC package, RθJA = 40 °C/W, AEC-Q101 qualified but not DO-160F tested | Valid for automotive load dump, insufficient for multi-stroke lightning standards | Choose for automotive OEM designs needing AEC-Q101 validation but lacking avionics certification needs. |
Compared with SMBJ100A and SMCJ100A, the MPLAD36KP100AE3 provides 24× and 24× higher peak pulse power respectively, certified DO-160F immunity, and 1.0 °C/W thermal resistance enabling reliable operation in high-reliability multi-stroke environments where lower-power alternatives would fail catastrophically.

FAQ
What is the clamping voltage of the MPLAD36KP100AE3 at its rated peak pulse current?
The MPLAD36KP100AE3 has a maximum clamping voltage (VC) of 162 V at 223 A peak pulse current (IPP), measured under the standard 10/1000 μs waveform. This value ensures downstream circuitry remains within safe operating voltage limits during high-energy transients, and is verified per test conditions in the RF01216 datasheet Figure 3.
Is the MPLAD36KP100AE3 compliant with DO-160F Section 22 lightning testing?
Yes, the MPLAD36KP100AE3 is specifically designed and tested to meet RTCA DO-160F Section 22 multi-stroke lightning requirements. It achieves Level 4 pin injection immunity for Waveform 4 (6.4/69 μs) up to 100 V and Level 5 for Waveform 5A (40/120 μs) up to 300 V, as documented in Microsemi's RF01216 Rev B specification.
How is thermal management implemented for the MPLAD36KP100AE3 in PCB layout?
The MPLAD36KP100AE3 relies on its metal base cathode as the primary thermal path. For optimal performance, the base must be soldered to a large copper pour or external heatsink using the recommended pad layout (11.94 × 5.85 mm). Its 1.0 °C/W junction-to-case thermal resistance enables >71 W steady-state dissipation at 100°C case temperature, as specified in the Absolute Maximum Ratings table.
Does the MPLAD36KP100AE3 meet automotive qualification standards?
Yes, the MPLAD36KP100AE3 is AEC-Q101 qualified, having undergone stress testing per the automotive discrete semiconductor reliability standard. This validates its suitability for under-hood and battery-line applications such as alternator load dump protection, though it exceeds typical automotive requirements with its DO-160F and IEC 61000-4-5 certifications.
What does the 'E3' suffix indicate in MPLAD36KP100AE3?
The 'E3' suffix in MPLAD36KP100AE3 denotes RoHS-compliant matte-tin plating per JEDEC J-STD-020B Level 1 moisture sensitivity. This ensures compatibility with lead-free reflow soldering processes without dry-pack requirements, and confirms conformance to environmental regulations while maintaining solderability per MIL-STD-750 Method 2026.
