Product details
Overview
MAPLAD36KP64CAE3 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 64 V reverse standoff voltage (VWM), clamps to ≤103.0 V at 350 A peak pulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP64CAE3 datasheet, MAPLAD36KP64CAE3 pinout, MAPLAD36KP64CAE3 application, or MAPLAD36KP64CAE3 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 and 5A, and ESD/EFT compliance per IEC 61000-4-2/-4.
Technical Context
This TVS diode operates as a voltage-clamped crowbar during transients, with breakdown voltage (V(BR)) specified at 71.1–78.6 V and clamping voltage (VC) ≤103.0 V at IPP = 350 A under 10/1000 μs waveform. Its low thermal resistance (RθJC = 1.0 °C/W) enables efficient heat dissipation when mounted on FR4 with recommended pad layout.
The bidirectional construction supports symmetrical surge suppression across polarity, and its UL94V-0 void-free epoxy package ensures mechanical robustness and flame resistance. Standby current (ID) is ≤10 μA at VWM = 64 V, supporting low-power system monitoring integrity.
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) | 64 V - maximum continuous operating voltage before conduction begins |
| Clamping Voltage (VC) | ≤103.0 V @ IPP = 350 A - limits downstream voltage stress during surge events |
| Breakdown Voltage (V(BR)) | 71.1–78.6 V @ 5 mA - defines onset of avalanche conduction with tight tolerance |
| Thermal Resistance (RθJC) | 1.0 °C/W - enables direct heat transfer to PCB copper or heatsink for thermal reliability |
| Standby Current (ID) | ≤10 μA @ 64 V - negligible leakage in standby, preserving signal integrity and power budget |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - no dry pack required, simplifies SMT handling and storage |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower PPP (600 W), smaller SMB package, higher RθJA (110 °C/W) | Suitable only for consumer-grade or low-energy industrial transients, not DO-160 or IEC 61000-4-5 Class 4/5 | Select when cost and board space constrain requirements and surge energy remains below 100 J |
| SMCJ64CA | PPP = 1500 W, SMC package, RθJA = 55 °C/W, same VWM but lower IPP (100 A) | Meets IEC 61000-4-5 Class 2–3, insufficient for multi-stroke lightning or long-distance Class 5 | Choose for automotive body electronics where full 36 kW capability is unnecessary |
Compared with SMBJ64CA and SMCJ64CA, MAPLAD36KP64CAE3 provides 60× and 24× higher peak pulse power respectively, enabling compliance with aviation lightning standards and long-duration industrial surges where thermal mass and clamping stability are critical.

FAQ
What is the clamping voltage of MAPLAD36KP64CAE3 at its rated peak pulse current?
The MAPLAD36KP64CAE3 has a maximum clamping voltage (VC) of 103.0 V at 350 A peak pulse current (IPP) under the standard 10/1000 μs waveform. This value is guaranteed across temperature and ensures downstream components remain within safe operating voltage limits during surge events. The clamping performance is validated per Figure 3 in RF01216 Rev B.
Is MAPLAD36KP64CAE3 suitable for automotive underhood applications?
Yes, MAPLAD36KP64CAE3 is AEC-Q101 qualified and rated for junction temperatures from –55 °C to +150 °C, making it suitable for underhood automotive applications such as engine control units and transmission control modules. Its bidirectional construction and 64 V standoff align with 24 V system architectures subject to load dump and ISO 7637-2 transients.
Does MAPLAD36KP64CAE3 require moisture-sensitive handling?
No, MAPLAD36KP64CAE3 is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it does not require dry pack storage or baking prior to reflow. This simplifies manufacturing logistics and eliminates moisture-related popcorning risks during standard lead-free soldering processes.
How does the PLAD package of MAPLAD36KP64CAE3 improve thermal performance compared to SMB or SMC packages?
The PLAD package of MAPLAD36KP64CAE3 achieves a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W - over 50× lower than typical SMB packages - due to its metal-base construction and optimized internal die attach. This allows direct heat transfer to the PCB copper pour or external heatsink, sustaining repeated 36 kW surges without thermal runaway.
Can MAPLAD36KP64CAE3 be used for RTCA DO-160 Section 22 lightning testing?
Yes, MAPLAD36KP64CAE3 is explicitly validated for RTCA DO-160 Section 22 multi-stroke lightning testing. Its 36,000 W PPP rating, fast response (<5 ns), and bidirectional symmetry enable reliable performance across Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) at Level 4 and Level 5, as confirmed in Microsemi's RF01216 Rev B documentation.
