Product details
Overview
MPLAD36KP160AE3 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, features a 160 V reverse standoff voltage (VWM), clamps to ≤259 V at 100 A IPP, and operates across –55°C to +150°C junction temperature.
For engineers reviewing the MPLAD36KP160AE3 datasheet, MPLAD36KP160AE3 pinout, MPLAD36KP160AE3 application, or MPLAD36KP160AE3 equivalent, key selection criteria include its DO-160 Section 22 multi-stroke lightning compliance, IEC 61000-4-5 Class 4/5 secondary lightning capability with 42 Ω source impedance, and RoHS-compliant e3 matte-tin terminations on a low-profile thermoset epoxy package.
Technical Context
This TVS diode uses an avalanche breakdown mechanism to clamp transients within nanoseconds, with <5 ns response time for bidirectional variants and sub-100 ps for unidirectional operation. Its metal-base cathode construction enables direct thermal coupling to PCB copper, achieving 1.0°C/W junction-to-case thermal resistance when mounted per recommended pad layout.
The device meets AEC-Q101 stress testing requirements and supports MIL-PRF-19500 upscreening options (M/MA/MXL levels). It provides certified ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and RTCA/DO-160F Waveform 4 & 5 pin-injection protection - validated for Level 4/5 at 160 V standoff in aircraft avionics interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SP3022-01ETG | Lower PPP (300 W), SOD-323 package, 160 V VWM, 275 V VC @ 1 A | Designed for board-level ESD only - not rated for DO-160 lightning or IEC 61000-4-5 Class 4/5 | Select only for low-energy signal-line protection where 36 kW surge handling is unnecessary |
| Vishay SMAJ160A | Same VWM (160 V), but 400 W PPP, DO-214AC package, 259 V VC @ 100 A | Lacks DO-160 qualification, AEC-Q101, and MIL-PRF-19500 screening options | Acceptable for cost-sensitive industrial controls where aerospace/automotive certification is not required |
Compared with Littelfuse SP3022-01ETG and Vishay SMAJ160A, the MPLAD36KP160AE3 uniquely combines 36 kW surge capacity, DO-160G Section 22 validation, and MIL-PRF-19500 upscreening - making it the only option for certified airborne lightning protection at 160 V standoff.

FAQ
What is the clamping voltage of MPLAD36KP160AE3 at its rated peak pulse current?
The MPLAD36KP160AE3 has a maximum clamping voltage (VC) of 259 V at 100 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is measured per Figure 3 in the RF01216 datasheet and defines the upper voltage limit imposed on protected circuits during surge events. The MPLAD36KP160AE3 maintains this clamping performance across its full operating temperature range.
Is MPLAD36KP160AE3 certified for DO-160 Section 22 lightning testing?
Yes, the MPLAD36KP160AE3 is explicitly validated for RTCA DO-160 Section 22 multi-stroke lightning testing per the RF01216 datasheet. It meets the standard's requirement for ≥1000 surge applications at rated PPP without parameter shift or catastrophic failure. This certification applies specifically to the MPLAD36KP160AE3 and is documented in Microsemi's test reports referenced in the datasheet.
Does MPLAD36KP160AE3 require special handling for moisture sensitivity?
No, the MPLAD36KP160AE3 is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions and does not require dry packing, baking, or floor-life tracking before reflow soldering. This eliminates moisture-related popcorning risk and simplifies manufacturing logistics for the MPLAD36KP160AE3.
What is the thermal resistance from junction to case for MPLAD36KP160AE3?
The MPLAD36KP160AE3 has a junction-to-case thermal resistance (RθJC) of 1.0°C/W, measured with the device mounted on a FR4 PCB using the recommended pad layout. This low value results from the metal-base cathode construction, enabling efficient heat transfer to the PCB copper or external heatsink - a critical parameter for sustaining repeated 36 kW surges in the MPLAD36KP160AE3.
Can MPLAD36KP160AE3 be used in bidirectional configurations?
No - the MPLAD36KP160AE3 is a unidirectional TVS diode, indicated by the "A" suffix (versus "CA" for bidirectional versions like MPLAD36KP160CA). Its cathode is the metal base, and it conducts only during reverse-biased transients. For bidirectional protection at 160 V standoff, the correct part is MPLAD36KP160CA, not the MPLAD36KP160AE3.
