Product details
Overview
MAPLAD36KP200CAE3 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 200 V reverse standoff voltage (VWM), clamps to ≤322 V at 112 A peak pulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP200CAE3 datasheet, MAPLAD36KP200CAE3 pinout, MAPLAD36KP200CAE3 application, or MAPLAD36KP200CAE3 equivalent, this device is selected for secondary lightning protection per IEC 61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), pin injection immunity per RTCA/DO-160F Waveform 4 & 5A, and high-reliability ESD/EFT suppression in avionics power rails and engine control units.
Technical Context
This TVS operates as a silicon avalanche diode with bidirectional clamping symmetry, enabling protection of AC-coupled or differential signal/power lines without polarity sensitivity. Its low thermal resistance (RθJC = 1.0 °C/W) and void-free UL94V-0 epoxy package support sustained multi-pulse operation under RTCA DO-160-compliant test profiles.
It is characterized at 25°C with 5 mA breakdown current (I(BR)), exhibits <100 ps response time from 0 V to V(BR) min, and maintains stable clamping performance across -55°C to +150°C junction temperature range - validated per AEC-Q101 stress testing and MIL-PRF-19500 upscreening options.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains aircraft lightning-induced surges without failure |
| Reverse Standoff Voltage (VWM) | 200 V - maximum continuous operating voltage before clamping initiates |
| Breakdown Voltage (V(BR)) | 222–245 V @ 5 mA - ensures reliable avalanche conduction onset above system peak rail |
| Max Clamping Voltage (VC) | 322 V @ 112 A IPP - limits downstream voltage stress during worst-case transients |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables efficient heat transfer to PCB copper pour or heatsink |
| Steady-State Power Dissipation | 71 W @ TC = 100°C - supports continuous thermal management in high-ambient environments |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - no dry pack required; compatible with standard SMT reflow |
Pinout & Package
MAPLAD36KP200CAE3 uses a surface-mount PLAD package with two terminals: anode and cathode. The metal base serves as the cathode terminal for unidirectional variants; for bidirectional devices like MAPLAD36KP200CAE3, both terminals are symmetrical and non-polarized. The package measures 12.32 × 10.54 × 5.08 mm (L × W × H) with tin-plated terminations compliant with MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during positive transient | Enables bidirectional clamping when paired with cathode; no polarity marking required |
| Cathode | Current exit point during positive transient | Symmetrical with anode in bidirectional construction; forms low-inductance path to ground or return |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Protects AC or floating DC lines without polarity constraints; eliminates orientation errors during placement |
| RTCA DO-160F Waveform 4 & 5A compliance | Withstands 6.4/69 μs and 40/120 μs pin-injection transients up to Level 5 (≤300 V VWM range) |
| AEC-Q101 qualified reliability | Validated for automotive under-hood applications including load dump and alternator ripple |
| RoHS-compliant e3 termination | Matte-tin plating ensures solderability and intermetallic stability in lead-free reflow profiles |
| IEC 61000-4-2/4-4/4-5 certified | Meets ESD (±8 kV contact), EFT (±2 kV), and surge (42 Ω, 12 Ω, 2 Ω source) immunity standards |
Applications
| Avionics Power Distribution | Automotive Engine Control Unit (ECU) |
|---|---|

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 SMAJ200CA | Lower PPP rating (400 W), smaller SMA package, higher RθJA (65 °C/W) | Suitable for consumer-grade 200 V circuits; insufficient for DO-160 multi-stroke or automotive load dump | Select only for cost-sensitive, low-energy applications where 36 kW capability is unnecessary |
| Vishay V200MLA0605 | Multi-layer varistor (MLV); 200 V RMS, 6 kA max IPP, no specified DO-160 compliance | Used in telecom AC inputs; lacks RTCA/IEC certification traceability and thermal derating data | Prefer for AC line filtering; avoid where aerospace qualification or precise clamping voltage is required |
Compared with MAPLAD36KP200CAE3, SMAJ200CA offers lower cost but cannot sustain multi-pulse lightning events, while V200MLA0605 provides broader frequency response but lacks documented DO-160F waveform validation and thermal performance data needed for safety-critical avionics.

FAQ
What is the clamping voltage of MAPLAD36KP200CAE3 at its rated peak pulse current?
The MAPLAD36KP200CAE3 has a maximum clamping voltage (VC) of 322 V at 112 A peak pulse current (IPP), measured under 10/1000 μs waveform conditions. This value ensures downstream components rated for ≤350 V withstand transient overvoltage without damage. The clamping performance is guaranteed across the full operating temperature range (-55°C to +150°C) and validated per AEC-Q101 stress testing protocols.
Is MAPLAD36KP200CAE3 certified for RTCA DO-160F lightning testing?
Yes, MAPLAD36KP200CAE3 is explicitly listed for RTCA DO-160F Section 22 multi-stroke lightning compliance, including Waveform 4 (6.4/69 μs) Level 4 and Level 5, and Waveform 5A (40/120 μs) Level 4 up to 78 V VWM and Level 5 up to 38 V VWM. Its 36,000 W PPP rating and low thermal resistance enable repeatable performance across multiple stroke sequences without degradation.
Does MAPLAD36KP200CAE3 require special PCB layout considerations?
Yes, MAPLAD36KP200CAE3 requires adherence to the recommended pad layout: 11.94 mm × 5.85 mm copper area with 2.44 mm solder mask opening. To minimize inductance and maximize thermal dissipation, use ≥2 oz copper, internal thermal vias under the metal base, and direct connection to solid ground/chassis planes. Avoid narrow traces between the device and protection target - keep path length under 10 mm.
What is the meaning of the 'CA' and 'E3' suffixes in MAPLAD36KP200CAE3?
In MAPLAD36KP200CAE3, 'CA' denotes bidirectional polarity configuration, distinguishing it from unidirectional 'A' variants. 'E3' specifies RoHS-compliant matte-tin plating per JEDEC J-STD-020B Level 1 moisture sensitivity - confirming no dry-pack requirement and compatibility with standard lead-free reflow profiles. Both suffixes are integral to the official Microsemi nomenclature and define electrical behavior and process compliance.
Can MAPLAD36KP200CAE3 be used in automotive applications?
Yes, MAPLAD36KP200CAE3 is AEC-Q101 qualified and validated for automotive use cases including 12 V/24 V load dump (ISO 7637-2 Pulse 5a), alternator ripple suppression, and ECU power rail protection. Its 200 V VWM aligns with 24 V system peak voltages, and its 36,000 W PPP rating exceeds typical automotive surge requirements - making it suitable for heavy-duty commercial vehicle and off-highway equipment designs.
