Product details
Overview
MPLAD36KP220CAE3 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace and automotive systems. It delivers 36 kW peak pulse power at 10/1000 μs, features a 220 V reverse standoff voltage (VWM), clamps transients to ≤356 V at 1000 A, and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MPLAD36KP220CAE3 datasheet, MPLAD36KP220CAE3 pinout, MPLAD36KP220CAE3 application, or MPLAD36KP220CAE3 equivalent, key selection criteria include bidirectional polarity, 220 V standoff rating, 356 V max clamping voltage at 1000 A, thermal resistance of 1.0 °C/W junction-to-case, and compliance with IEC 61000-4-5 (Class 3–5) and RTCA DO-160F Waveform 4 Level 4.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered by avalanche breakdown, with symmetrical bidirectional conduction enabling protection against both positive and negative transients. Its low RθJC (1.0 °C/W) and void-free thermosetting epoxy package support high-reliability mounting on FR4 PCBs with thermal pad layout per specification.
It is characterized for operation across –55°C to +150°C junction temperature, with standby current ≤10 μA at VWM, and exhibits a ±20 mV/°C temperature coefficient of breakdown voltage. Surge testing follows AEC-Q101 and includes 100% lot-level surge validation per MIL-PRF-19500 screening options.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 36,000 W @ 10/1000 μs - sustains aircraft lightning-induced surges without failure |
| Reverse Standoff Voltage (VWM) | 220 V - maximum continuous operating voltage before clamping initiates |
| Max Clamping Voltage (VC) | 356 V @ 1000 A - limits downstream circuit voltage during worst-case surge |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables effective heat transfer to heatsink or copper pour |
| Standby Current (ID) | ≤10 μA @ 220 V - negligible leakage in normal operation |
| Breakdown Voltage Range | 245–271 V @ 5 mA - ensures reliable turn-on margin above VWM |
| Temperature Coefficient | ±20 mV/°C - predictable VBR drift over full operating range |
Pinout & Package
Surface-mount PLAD package with metal base cathode (bidirectional symmetry eliminates anode/cathode distinction); dimensions: 12.32 × 10.54 × 5.08 mm (L × W × H); RoHS-compliant matte-tin plating; weight ≈1.85 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | 600 W PPP rating, SMC package, 356 V VC @ 17.3 A - 59× lower peak power capability | Only suitable for low-energy industrial I/O, not DO-160 or load dump | Select only when surge energy is <10 J and PCB space is constrained |
| SMCJ220CA | 1500 W PPP rating, same SMC package, 356 V VC @ 85 A - 24× lower peak power than MPLAD36KP220CAE3 | Acceptable for ISO 7637-2 Pulse 1/2, but fails DO-160 Section 22 multi-stroke validation | Use where cost sensitivity outweighs aerospace/automotive qualification requirements |
Compared with SMBJ220CA and SMCJ220CA, the MPLAD36KP220CAE3 provides 36 kW clamping capacity - essential for certified lightning protection - while maintaining identical 220 V standoff and 356 V clamping voltage, enabling direct functional replacement in high-reliability designs where energy handling is the limiting factor.

FAQ
What is the clamping voltage of MPLAD36KP220CAE3 at its rated peak pulse current?
The MPLAD36KP220CAE3 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 across the full operating temperature range and forms the basis for downstream circuit voltage margining in lightning and load dump protection designs.
Is MPLAD36KP220CAE3 suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the MPLAD36KP220CAE3 is tested and qualified to AEC-Q101 standards for stress testing including temperature cycling, humidity bias, and mechanical shock. Its 220 V standoff and 356 V clamping performance meet ISO 7637-2 Pulse 5a requirements for 24 V commercial vehicle systems when properly mounted with thermal pad.
Does MPLAD36KP220CAE3 require special handling due to moisture sensitivity?
No, the MPLAD36KP220CAE3 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 or baking prior to reflow soldering - simplifying manufacturing logistics and reducing process risk.
How does the bidirectional design of MPLAD36KP220CAE3 affect PCB layout?
The bidirectional construction of MPLAD36KP220CAE3 eliminates polarity constraints: either terminal may connect to line or ground, and the metal base serves as the common thermal path. Layout requires only a symmetric 2-pad footprint with a dedicated thermal copper pour beneath the base, per the documented pad layout (Ref. A=11.94 mm, B=5.85 mm).
Can MPLAD36KP220CAE3 be used in RTCA DO-160 Section 22 lightning protection?
Yes, the MPLAD36KP220CAE3 is explicitly validated for RTCA DO-160F Section 22 multi-stroke lightning testing (Waveform 4 Level 4, 6.4/69 μs), supporting 220 V standoff systems. Its 36 kW rating and thermal design enable repeated surge endurance without parametric shift or catastrophic failure.
