Product details
Overview
MPLAD36KP220AE3 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 transients to ≤356 V at 1000 A, and features a 220 V reverse standoff voltage (VWM), 245–271 V breakdown voltage (V(BR)), and 1.0 °C/W junction-to-case thermal resistance.
For engineers reviewing the MPLAD36KP220AE3 datasheet, MPLAD36KP220AE3 pinout, MPLAD36KP220AE3 application, or MPLAD36KP220AE3 equivalent, this device is selected for secondary lightning protection per IEC 61000-4-5 (42 Ω, 12 Ω, 2 Ω source impedances), RTCA DO-160F Waveform 4 & 5A pin injection, and load dump suppression where low thermal resistance and RoHS-compliant packaging are critical.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, triggering when transient voltage exceeds its V(BR) range of 245–271 V at 5 mA. Its metal-base cathode construction enables direct thermal coupling to PCB copper or heatsinks, supporting sustained energy dissipation under multi-stroke lightning conditions.
It meets AEC-Q101 stress testing requirements and supports IEC 61000-4-2/4-4/4-5, RTCA DO-160F Waveform 4 (6.4/69 μs) Level 4–5, and Waveform 5A (40/120 μs) Level 4–5 - with derating applied per MicroNote 132 for temperature-dependent clamping performance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SP36-220 | Same 220 V VWM and 36 kW rating, but TO-277 package (higher RθJA = 25 °C/W) | Requires external heatsinking for multi-stroke duty; not qualified to DO-160F | Select when cost sensitivity outweighs aerospace qualification and thermal performance needs |
| Vishay SMAJ220A | Lower PPP (400 W), smaller SMA package, 220 V VWM, 356 V VC | Only suitable for low-energy ESD/EFT - not rated for lightning or load dump | Use only for board-level ESD protection where surge energy is <10 J |
Compared with SP36-220 and SMAJ220A, the MPLAD36KP220AE3 uniquely combines aerospace qualification (DO-160F), ultra-low thermal resistance (1.0 °C/W), and full 36 kW lightning capability in a surface-mount form - making it irreplaceable for certified avionics and high-reliability industrial power systems.

FAQ
What is the clamping voltage of MPLAD36KP220AE3 at its rated peak pulse current?
The MPLAD36KP220AE3 has a maximum clamping voltage (VC) of 356 V at 1000 A peak pulse current under 10/1000 μs waveform conditions. This value is guaranteed per datasheet Figure 3 and ensures downstream components experience controlled overvoltage stress during surge events. The clamping behavior is validated across temperature and production lots per AEC-Q101 test requirements.
Is MPLAD36KP220AE3 qualified for RTCA DO-160F lightning testing?
Yes, MPLAD36KP220AE3 is explicitly rated for RTCA DO-160F Section 22 (lightning-induced transient) and Section 25 (pin injection) testing. It achieves Level 4 for Waveform 4 (6.4/69 μs) and Level 4 for Waveform 5A (40/120 μs) at 220 V VWM, as confirmed in RF01216 Rev B. Derating guidance for elevated ambient temperatures is provided in MicroNote 132.
How does the PLAD package of MPLAD36KP220AE3 improve thermal performance?
The PLAD package places the cathode on the metal base, enabling direct thermal conduction from the silicon junction to PCB copper or an external heatsink. With a measured junction-to-case thermal resistance of 1.0 °C/W, MPLAD36KP220AE3 achieves significantly lower temperature rise than TO-277 or SMA alternatives - critical for sustaining multi-stroke lightning events without thermal runaway.
Does MPLAD36KP220AE3 meet automotive reliability standards?
Yes, MPLAD36KP220AE3 is tested and qualified to AEC-Q101 for discrete semiconductors. It undergoes stress testing including HTGB, HTRB, TST, and surge endurance - confirming suitability for under-hood automotive applications such as 48 V battery systems and ADAS power modules where load dump immunity is mandatory.
What is the moisture sensitivity level (MSL) and reflow profile for MPLAD36KP220AE3?
MPLAD36KP220AE3 is rated MSL Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and requires no dry pack or baking prior to reflow. Its recommended reflow peak temperature is 260 °C for 10 seconds, compatible with standard lead-free SMT processes. The e3 RoHS-compliant matte-tin terminations ensure reliable wetting and joint integrity.
