Product details
Overview
MAPLAD36KP30CA 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 30 V reverse standoff voltage (VWM), clamps to ≤48.8 V at 738 A peak pulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP30CA datasheet, MAPLAD36KP30CA pinout, MAPLAD36KP30CA application, or MAPLAD36KP30CA 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 protection per RTCA/DO-160F Waveform 4 (Level 4 up to 400 V), and ESD/EFT immunity per IEC 61000-4-2/4-4.
Technical Context
The MAPLAD36KP30CA employs an avalanche breakdown mechanism to clamp transients within nanoseconds, with <5 ns response time for bidirectional operation. Its low thermal resistance (RθJC = 1.0 °C/W) enables efficient heat transfer to the PCB copper pad, supporting repeated surge events under ≤0.05% duty factor.
It operates across –55°C to +150°C junction temperature range and maintains stable clamping performance under RTCA DO-160F Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs), with derating guidance provided for elevated ambient temperatures per Figure 3.
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) | 30 V - maximum continuous operating voltage before clamping initiates |
| Breakdown Voltage (V(BR)) | 33.3–36.8 V @ 5 mA - ensures reliable turn-on margin above VWM |
| Max Clamping Voltage (VC) | 48.8 V @ 738 A IPP - limits downstream circuit stress during worst-case surge |
| Peak Pulse Current (IPP) | 738 A @ 10/1000 μs - defines maximum surge current the device can safely divert |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables direct thermal coupling to heatsinked PCB pads for multi-pulse reliability |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - no dry pack or bake required prior to reflow |
Pinout & Package
MAPLAD36KP30CA uses a surface-mount PLAD package with metal base cathode (bidirectional symmetry eliminates polarity dependency). The package measures 12.32 × 10.54 × 5.08 mm (L × W × H) and mounts via two large solder pads on FR4 PCB using recommended pad layout (A = 11.94 mm, B = 5.85 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Surge current path terminal | Bidirectional conduction allows placement without orientation check; metal base serves as primary thermal and electrical interface |
| Metal base (bottom) | Common terminal / thermal path | Functions as both current return path and primary heat sink-must be soldered to ≥100 mm² copper pour for RθJA ≤50 °C/W |

FAQ
What is the clamping voltage of MAPLAD36KP30CA at its rated peak pulse current?
The MAPLAD36KP30CA exhibits a maximum clamping voltage (VC) of 48.8 V when subjected to its rated peak pulse current of 738 A under 10/1000 μs waveform conditions. This value is measured per standard test methods defined in the datasheet and ensures downstream circuitry remains below critical overvoltage thresholds during surge events. The clamping performance is guaranteed across the full operating temperature range of –55°C to +150°C.
Is MAPLAD36KP30CA qualified to AEC-Q101 standards?
Yes, MAPLAD36KP30CA is tested and qualified to AEC-Q101 standards for discrete semiconductors. This includes stress tests such as high-temperature operating life, temperature cycling, and surge current endurance. The qualification confirms suitability for automotive under-hood and powertrain applications where reliability under thermal and electrical stress is mandatory. Full test reports are available upon request through Aetrix Electronics.
Does MAPLAD36KP30CA require moisture sensitivity handling before reflow soldering?
No, MAPLAD36KP30CA is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry packing or baking. This eliminates moisture-related popcorning risk during lead-free reflow (peak 260°C for 10 s), simplifying manufacturing logistics for high-volume PCB assembly lines.
How does the PLAD package of MAPLAD36KP30CA improve thermal performance compared to standard SMC packages?
The PLAD package of MAPLAD36KP30CA features a metal base that serves as both electrical terminal and primary thermal path, achieving a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W - over 2× better than typical SMC packages (~2.5 °C/W). When soldered to a minimum 100 mm² copper pad, it maintains RθJA ≤50 °C/W, enabling sustained multi-pulse operation without thermal runaway.
Can MAPLAD36KP30CA be used for RTCA DO-160F Section 22 lightning testing?
Yes, MAPLAD36KP30CA is explicitly validated for RTCA DO-160F Section 22 multi-stroke lightning testing. Its 36,000 W peak pulse power rating, sub-5 ns response time, and robust construction allow it to withstand repeated 10/1000 μs surges at full energy - a requirement for aircraft-level certification. Data sheets cite compliance for Level 4 pin injection (Waveform 4) and full Section 22 waveform families.
