Product details
Overview
MXPLAD36KP22CAE3 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace and automotive systems. It delivers 36,000 W peak pulse power at 10/1000 μs, features a 22 V reverse standoff voltage (VWM), clamps to ≤36.4 V at 990 A peak pulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements for aircraft electronics.
For engineers reviewing the MXPLAD36KP22CAE3 datasheet, MXPLAD36KP22CAE3 pinout, MXPLAD36KP22CAE3 application, or MXPLAD36KP22CAE3 equivalent, this device is selected for secondary lightning protection per IEC 61000-4-5 (with 2 Ω, 12 Ω, and 42 Ω source impedances), pin injection immunity per RTCA/DO-160F Waveform 4 and 5A, and ESD/EFT compliance per IEC 61000-4-2 and -4-4.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during transients, with bidirectional symmetry enabling protection against both polarities of surge events. Its low thermal resistance (RθJC = 1.0 °C/W) and void-free UL94V-0 epoxy package support high-reliability mounting on FR4 PCBs with recommended pad layout.
It is characterized by a breakdown voltage range of 24.4–26.9 V at 5 mA, a maximum clamping voltage of 36.4 V at 990 A, and a temperature coefficient of breakdown voltage (αV(BR)) of +20 mV/°C - enabling predictable derating across –55°C to +150°C operating junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains aircraft-grade lightning surges without failure |
| Reverse Standoff Voltage (VWM) | 22 V - sets maximum continuous operating voltage before clamping initiates |
| Breakdown Voltage (V(BR)) | 24.4–26.9 V @ 5 mA - defines precise turn-on threshold for bidirectional conduction |
| Clamping Voltage (VC) | ≤36.4 V @ 990 A IPP - limits downstream circuit voltage stress during worst-case surge |
| Peak Pulse Current (IPP) | 990 A @ 10/1000 μs - quantifies maximum surge current handled at rated clamping level |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables efficient heat transfer to heatsink or copper pour for repeated surge duty |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - allows standard SMT reflow without dry-pack preconditioning |
Pinout & Package
MXPLAD36KP22CAE3 uses a surface-mount PLAD package with two terminals: anode and cathode formed on opposite sides of the metal base. The cathode is the metal base under the body (per datasheet polarity note); for bidirectional operation, polarity is symmetrical and non-directional in circuit placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal for unidirectional mode; one side of symmetric bidirectional path | Connected to line or signal trace requiring protection; forms low-impedance shunt path during overvoltage |
| Cathode | Negative terminal for unidirectional mode; other side of symmetric bidirectional path | Mounted to ground plane or return path; completes clamping loop with minimal inductance via metal-base thermal interface |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction (CA suffix) | Enables single-device protection of AC lines, differential buses, or floating signals without polarity constraints |
| RTCA DO-160 Section 22 compliance | Validated for multi-stroke lightning testing - critical for avionics certification and DO-160G qualification |
| IEC 61000-4-5 Class 5 support (42 Ω, short distance) | Meets highest industrial lightning immunity tier for equipment installed near service entrances or outdoor interfaces |
| AEC-Q101 qualified | Qualified for automotive under-hood and powertrain applications requiring robust surge resilience and temperature cycling reliability |
| RoHS-compliant matte-tin plating (e3) | Ensures lead-free solder compatibility and long-term intermetallic stability in high-reliability reflow profiles |

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 SP3022-01ETG | Unidirectional, 22 V VWM, 300 W PPP, SOD-323 package | Lower energy rating; suited only for board-level ESD, not lightning or load dump | Select when protecting low-energy signal lines where PCB space is constrained and surge levels are <100 A. |
| Vishay SMAJ22CA | Bidirectional, 22 V VWM, 400 W PPP, SMA package | 100× lower peak power; lacks RTCA DO-160 or AEC-Q101 qualification | Use for cost-sensitive industrial controls where IEC 61000-4-2/4-4 suffices but lightning immunity is not required. |

FAQ
What is the clamping voltage of MXPLAD36KP22CAE3 at its rated peak pulse current?
The MXPLAD36KP22CAE3 has a maximum clamping voltage (VC) of 36.4 V when subjected to its rated peak pulse current of 990 A under 10/1000 μs waveform conditions. This value is guaranteed across the full operating temperature range and is measured with the device mounted per the recommended FR4 pad layout. The clamping performance ensures downstream circuitry remains within safe voltage margins during high-energy transients.
Is MXPLAD36KP22CAE3 qualified for automotive applications?
Yes, MXPLAD36KP22CAE3 is AEC-Q101 qualified, confirming its suitability for automotive powertrain and chassis applications subject to harsh thermal cycling, mechanical vibration, and high-energy electrical transients. Its qualification supports use in engine control modules, battery management systems, and ADAS power supplies where load dump and jump-start surges must be reliably suppressed.
Does MXPLAD36KP22CAE3 require dry pack handling prior to reflow soldering?
No, MXPLAD36KP22CAE3 is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored and processed under standard factory conditions without baking or dry pack. This eliminates moisture-related popcorning risk during standard lead-free reflow profiles and simplifies manufacturing logistics for high-reliability assembly lines.
How does the bidirectional construction of MXPLAD36KP22CAE3 affect PCB layout?
The bidirectional design of MXPLAD36KP22CAE3 eliminates polarity sensitivity - the device can be placed without orientation constraints on AC-coupled lines, differential pairs, or floating grounds. Its metal-base cathode serves as both thermal path and low-inductance return node, so layout should prioritize direct connection of the base to a large copper pour or heatsink rather than routing discrete traces to either terminal.
Can MXPLAD36KP22CAE3 be used for RTCA DO-160 Section 22 multi-stroke lightning testing?
Yes, MXPLAD36KP22CAE3 is explicitly validated for RTCA DO-160 Section 22 multi-stroke lightning testing, as confirmed in the RF01216 datasheet. Its 36 kW pulse rating, low thermal resistance, and cumulative heating mitigation features enable reliable performance across repeated stroke sequences - a requirement for Level A/B/C avionics equipment certification.
