Product details
Overview
MAPLAD36KP100CA from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power systems. It delivers 36 kW peak pulse power at 10/1000 μs, features a 100 V reverse standoff voltage (VWM), clamps to ≤162 V at 223 A peak impulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP100CA datasheet, MAPLAD36KP100CA pinout, MAPLAD36KP100CA application, or MAPLAD36KP100CA 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 (Level 4 up to 400 V), and ESD/EFT compliance per IEC 61000-4-2/4-4.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during transients, leveraging avalanche breakdown across its bidirectional junction to shunt surge energy away from sensitive circuitry. Its low thermal resistance (RθJC = 1.0 °C/W) and void-free thermosetting epoxy package enable rapid heat dissipation under repetitive 0.05% duty-cycle surges.
The device is characterized with 5 mA breakdown test current (I(BR)), exhibits <10 μA standby current (ID) at VWM, and maintains stable clamping performance across -55°C to +150°C operating junction temperature - validated per AEC-Q101 and MIL-PRF-19500 screening options.
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) | 100 V - maximum continuous DC or peak AC voltage before clamping initiates |
| Breakdown Voltage (V(BR)) | 111–123 V @ 5 mA - ensures reliable turn-on margin above VWM for robust triggering |
| Clamping Voltage (VC) | ≤162 V @ IPP = 223 A - limits downstream voltage stress to safe levels during surge |
| Peak Pulse Current (IPP) | 223 A @ 10/1000 μs - quantifies maximum surge current safely diverted to ground |
| Thermal Resistance (RθJC) | 1.0 °C/W - enables efficient heat transfer to heatsink or PCB copper for thermal reliability |
| Standby Current (ID) | ≤10 μA @ VWM - negligible leakage in normal operation, critical for low-power systems |
Pinout & Package
MAPLAD36KP100CA uses a surface-mount PLAD package (void-free UL94V-0 epoxy body) with two terminals: anode and cathode symmetrically arranged on opposite ends of the metal base. The metal base serves as the common thermal path and electrical connection point; polarity is not marked on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (End Terminal) | Surge current entry point (bidirectional) | Accepts transient energy from either polarity; connects to protected line or signal path |
| Cathode (End Terminal) | Surge current return path (bidirectional) | Completes low-inductance path to ground plane or chassis; shares thermal mass with base |
| Metal Base | Thermal & electrical reference plane | Provides primary heat conduction path to PCB copper pour or heatsink; electrically tied to cathode in unidirectional versions only |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Protects AC lines and differential signals without polarity constraints; eliminates need for dual-device placement |
| RTCA DO-160F Waveform 4 compliance (Level 4) | Withstands 6.4/69 μs pin-injection transients up to 400 V - certified for avionics interface protection |
| AEC-Q101 qualified construction | Validated for automotive under-hood environments including thermal cycling, humidity, and mechanical shock |
| Moisture Sensitivity Level 1 | No dry pack or baking required before reflow - reduces manufacturing overhead and handling risk |
| RoHS-compliant (e3 marking) | Tin-plated terminals meet lead-free soldering standards and environmental compliance mandates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPP (600 W), smaller SMB package, 100 V VWM, 165 V VC @ 3.5 A IPP | Only suitable for low-energy transients (IEC 61000-4-2/4-4); cannot meet DO-160 lightning or load dump requirements | Select when board space is constrained and surge energy is limited to <10 J - not a drop-in replacement for MAPLAD36KP100CA. |
| SMCJ100CA | Higher PPP (1500 W), SMC package, same 100 V VWM, 165 V VC @ 11.8 A IPP | Meets IEC 61000-4-5 Class 3 (42 Ω), but fails Class 4/5 and DO-160F Waveform 4/5A testing | Use where moderate surge immunity is needed and cost is prioritized over aerospace-grade certification. |
Compared with SMBJ100CA and SMCJ100CA, MAPLAD36KP100CA delivers 24× and 24× higher peak pulse power respectively, enabling compliance with RTCA DO-160F lightning standards and automotive load dump - making it the only option among the three qualified for mission-critical avionics and heavy-duty vehicle electronics.

FAQ
What is the clamping voltage of MAPLAD36KP100CA at its rated peak pulse current?
The MAPLAD36KP100CA has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak pulse current of 223 A under 10/1000 μs waveform conditions. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream components remain within absolute maximum ratings.
Does MAPLAD36KP100CA require moisture sensitivity handling prior to reflow soldering?
No, MAPLAD36KP100CA is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored and processed without dry packing or baking. This eliminates pre-reflow moisture mitigation steps, reducing manufacturing complexity and avoiding potential delamination risks associated with improper bake cycles.
Is MAPLAD36KP100CA qualified for automotive under-hood applications?
Yes, MAPLAD36KP100CA is constructed and tested to AEC-Q101 standards, validating its reliability under automotive under-hood conditions including temperature cycling (-55°C to +150°C), humidity, and mechanical shock. Its 100 V VWM and 162 V clamping align with ISO 7637-2 Pulse 5a/b load dump requirements for 24 V systems.
How does MAPLAD36KP100CA perform in RTCA DO-160F lightning testing?
MAPLAD36KP100CA is explicitly rated for RTCA DO-160F Section 22 multi-stroke lightning testing. It achieves Level 4 pin injection protection per Waveform 4 (6.4/69 μs) up to 400 V standoff and supports full Class 4/5 secondary lightning protection per IEC 61000-4-5 with 42 Ω source impedance - confirmed in Microsemi RF01216 Rev B documentation.
What is the thermal resistance from junction to case for MAPLAD36KP100CA?
The MAPLAD36KP100CA has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W, measured with the device mounted on a heatsink per specification. This low value enables effective heat extraction during repetitive surge events, supporting stable operation even at 0.05% duty cycle - essential for systems exposed to frequent transient activity.
