Product details
Overview
MAPLAD36KP100CAE3 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 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 operates across –55°C to +150°C junction temperature. It is qualified to AEC-Q101 and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP100CAE3 datasheet, MAPLAD36KP100CAE3 pinout, MAPLAD36KP100CAE3 application, or MAPLAD36KP100CAE3 equivalent, key selection criteria include its bidirectional polarity, 1.0°C/W junction-to-case thermal resistance, RoHS-compliant e3 plating, IEC 61000-4-5 Class 5 secondary lightning protection capability (with 42 Ω source), and compatibility with FR4 PCB mounting per recommended pad layout.
Technical Context
This TVS diode uses silicon avalanche technology to provide fast-response clamping against high-energy transients. Its metal-base package enables low thermal resistance (RθJC = 1.0°C/W) and direct heat sinking to the PCB ground plane. The bidirectional construction allows symmetric suppression of positive and negative polarity surges without polarity-sensitive placement.
It is characterized for operation under strict aerospace environmental stress: tested per RTCA/DO-160F Waveform 4 (6.4/69 μs) Level 4 and Waveform 5A (40/120 μs) Level 4, and validated for secondary lightning protection per IEC 61000-4-5 up to Class 5 with 42 Ω source impedance. Standby leakage (ID) is 10 μA max at 100 V VWM.
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) | 100 V - maximum continuous operating voltage before clamping initiates |
| Clamping Voltage (VC) | ≤162 V @ IPP = 223 A - limits downstream circuit voltage during worst-case surge |
| Peak Impulse Current (IPP) | 223 A @ 10/1000 μs - quantifies maximum surge current it can divert safely |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables efficient heat transfer to PCB copper pour or heatsink |
| Operating Temperature Range | –55°C to +150°C - supports deployment in engine bays, avionics bays, and outdoor enclosures |

Pinout & Package
The MAPLAD36KP100CAE3 is housed in a low-profile, void-free thermosetting epoxy PLAD package (UL94V-0 rated) with a metal base acting as the cathode terminal for unidirectional variants; for bidirectional devices like MAPLAD36KP100CAE3, both terminals are symmetrical and non-polarized. The package measures 12.32 mm × 10.54 mm × 5.08 mm (L×W×H) and weighs ~1.85 g.

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 | 600 W PPP rating, SMC package, RθJC ≈ 12°C/W - lower power handling and higher thermal resistance | Suitable only for sub-100 A surges; not qualified for RTCA DO-160 or IEC 61000-4-5 Class 5 | Select when cost sensitivity outweighs aerospace/automotive qualification needs and surge energy is <10% of MAPLAD36KP100CAE3 capability |
| SMCJ100CA | 1500 W PPP rating, same SMC package footprint but lower clamping (VC = 170 V @ 8.3 A) - insufficient for multi-kA threats | Lacks AEC-Q101 qualification and RTCA DO-160 testing; limited to industrial-grade surge environments | Choose only for non-safety-critical industrial controls where peak current remains below 10 A and thermal margin is ample |
Compared with SMBJ100CA and SMCJ100CA, MAPLAD36KP100CAE3 provides 24× and 24× higher peak pulse power respectively, certified thermal performance for PCB-mounted heat sinking, and full aerospace-grade transient immunity validation - making it irreplaceable in certified aviation and high-reliability automotive power protection.

FAQ
What is the clamping voltage of MAPLAD36KP100CAE3 at its rated peak impulse current?
The MAPLAD36KP100CAE3 has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak impulse current of 223 A under 10/1000 μs waveform conditions. This value is guaranteed across the full operating temperature range and ensures downstream circuitry remains within safe voltage limits during high-energy transients.
Is MAPLAD36KP100CAE3 qualified for automotive applications?
Yes, MAPLAD36KP100CAE3 is AEC-Q101 qualified and explicitly designed for automotive load-dump protection. Its 100 V VWM matches standard 24 V system architectures, and its 36 kW PPP rating handles worst-case alternator transients. It also meets ISO 7637-2 Pulse 5a/b requirements when applied per recommended PCB layout.
Does MAPLAD36KP100CAE3 require a heatsink for reliable operation?
No discrete heatsink is required. MAPLAD36KP100CAE3 achieves 1.0°C/W junction-to-case thermal resistance through its metal-base PLAD package, enabling direct thermal coupling to PCB copper pours or internal ground planes. Full 36 kW pulse handling is validated on FR4 with the manufacturer-recommended pad layout (11.94 mm × 5.85 mm thermal pad).
How does the CA suffix in MAPLAD36KP100CAE3 indicate device functionality?
The "CA" suffix in MAPLAD36KP100CAE3 denotes bidirectional construction - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional "A" variants, MAPLAD36KP100CAE3 has no anode/cathode distinction and may be mounted in either orientation on the PCB.
What standards does MAPLAD36KP100CAE3 meet for lightning protection?
MAPLAD36KP100CAE3 meets RTCA DO-160 Section 22 multi-stroke lightning requirements for aircraft equipment and IEC 61000-4-5 Class 5 secondary lightning protection with 42 Ω source impedance. It is also validated for pin-injection immunity per DO-160F Waveform 4 (Level 4) and Waveform 5A (Level 4), confirming robustness in high-field radiated environments.
