Product details
Overview
MAPLAD36KP36CAE3 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 36 V reverse standoff voltage (VWM), clamps to ≤58.1 V at 620 A peak pulse current, and operates across –55°C to +150°C junction temperature - deployed in aircraft lightning protection per RTCA DO-160 Section 22.
For engineers reviewing the MAPLAD36KP36CAE3 datasheet, MAPLAD36KP36CAE3 pinout, MAPLAD36KP36CAE3 application, or MAPLAD36KP36CAE3 equivalent, this device is selected for secondary lightning protection (IEC 61000-4-5), pin-injection immunity (DO-160F Waveform 4 Level 4), and high-reliability load dump suppression where low thermal resistance and RoHS-compliant e3 plating are required.
Technical Context
This TVS diode uses an avalanche breakdown mechanism to clamp transients within nanoseconds, with <5 ns response time for bidirectional operation. Its void-free UL94V-0 epoxy package and metal-base cathode construction enable direct thermal coupling to PCB copper, achieving 1.0°C/W junction-to-case thermal resistance.
It meets AEC-Q101 stress testing requirements and supports MIL-PRF-19500 upscreening options. Electrical performance is validated under 0.05% duty factor impulse repetition, with derated PPP above 100°C case temperature per Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains multi-stroke lightning surges without degradation |
| Reverse Standoff Voltage (VWM) | 36 V - maximum continuous operating voltage before clamping initiates |
| Clamping Voltage (VC) | ≤58.1 V @ 620 A IPP - limits downstream circuit voltage during worst-case surge |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables efficient heat transfer to heatsink or copper pour |
| Operating Temperature Range | –55°C to +150°C - qualified for extended-range aerospace and engine bay environments |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - no dry pack or bake required prior to reflow |
| RoHS Compliance | e3 matte-tin plating - lead-free, solderable per MIL-STD-750 Method 2026 |
Pinout & Package
MAPLAD36KP36CAE3 uses a PLAD (Plastic Leaded Anode/Cathode) surface-mount package with metal base cathode terminal. The device has two terminals: anode (top-side metallization) and cathode (exposed metal base), enabling low-inductance mounting directly to thermal pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive surge path input | Top-side solderable pad; connects to protected line (e.g., avionics bus) |
| Cathode | Common reference / ground return | Exposed metal base; must be soldered to large copper area for thermal and electrical performance |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Protects AC-coupled or floating lines against ± polarity surges without polarity constraints |
| RTCA DO-160F Waveform 4 Level 4 compliance | Withstands 6.4/69 μs pin-injection transients up to 36 V VWM devices - certified for aircraft subsystems |
| IEC 61000-4-5 Class 4 support (42 Ω source) | Validated for secondary lightning protection in long-distance wiring configurations (up to 260 V VWM) |
| 3σ lot norm screening on ID | Ensures consistent standby leakage (<10 μA @ 36 V) across production lots for low-power system integrity |
| MIL-PRF-19500 upscreening option | Enables high-reliability qualification for military/aerospace programs requiring traceable wafer and assembly lots |

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 SMAJ36CA | Lower PPP (400 W), smaller SMA package, 1.5°C/W RθJA, unidirectional/bidirectional variants available | Suitable for consumer-grade or non-safety-critical industrial use; not qualified for DO-160 or AEC-Q101 | Select when cost and board space constrain requirements and aerospace/automotive qualification is unnecessary |
| Vishay V26MLA0603NH | MLA varistor-based, 26 V nominal, 120 J energy rating, SMD 0603, no polarity, higher capacitance (~300 pF) | Better for lower-voltage, high-frequency ESD; unsuitable for 36 kW lightning pulses due to energy density limits | Choose for board-level ESD near IC pins rather than system-level surge suppression at power inputs |
Compared with MAPLAD36KP36CAE3, SMAJ36CA offers compact size but lacks multi-kW surge capability and aerospace qualification, while V26MLA0603NH provides low-capacitance ESD clamping but cannot sustain 620 A peak currents - MAPLAD36KP36CAE3 remains uniquely suited for certified high-energy transient suppression.

FAQ
What is the clamping voltage of MAPLAD36KP36CAE3 at its rated peak pulse current?
The MAPLAD36KP36CAE3 has a maximum clamping voltage (VC) of 58.1 V at 620 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value ensures downstream components see limited overvoltage during worst-case transients, and it is measured with case temperature controlled per specification.
Is MAPLAD36KP36CAE3 qualified for automotive applications?
Yes, MAPLAD36KP36CAE3 is tested in accordance with AEC-Q101 requirements for discrete semiconductors. Its 36 V standoff, bidirectional operation, and 36 kW surge rating make it suitable for 48V automotive load dump protection, especially in ADAS and domain controller power inputs where high-energy transients occur.
Does MAPLAD36KP36CAE3 require a heatsink for reliable operation?
MAPLAD36KP36CAE3 does not require an external heatsink but relies on PCB copper area for thermal management. Its 1.0°C/W junction-to-case thermal resistance demands a minimum recommended pad layout (0.470" × 0.230") with direct connection to internal ground planes or thermal vias to maintain TJ ≤150°C under repeated surge conditions.
What does the 'CA' suffix indicate in MAPLAD36KP36CAE3?
The 'CA' suffix in MAPLAD36KP36CAE3 denotes bidirectional construction - meaning the device clamps transients of either polarity symmetrically. This distinguishes it from unidirectional versions (e.g., MAPLAD36KP36AE3) and is essential for protecting AC-coupled or floating signal/power lines in aerospace and railway systems.
How is MAPLAD36KP36CAE3 marked and packaged for production use?
MAPLAD36KP36CAE3 is marked on the body with its full part number and supplied in tape-and-reel format (EIA-481-B compliant) when ordered with 'TR' suffix. The 'e3' suffix confirms RoHS-compliant matte-tin plating, and the device weighs approximately 1.7–2.0 g with UL94V-0 void-free epoxy encapsulation.
