Product details
Overview
MAPLAD36KP110CAE3 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 110 V reverse standoff voltage (VWM), clamps to ≤177 V at 204 A peak impulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP110CAE3 datasheet, MAPLAD36KP110CAE3 pinout, MAPLAD36KP110CAE3 application, or MAPLAD36KP110CAE3 equivalent, key selection criteria include its bidirectional polarity, 1.0 °C/W junction-to-case thermal resistance, RoHS-compliant e3 termination, IEC 61000-4-5 Class 5 secondary lightning protection capability, and suitability for pin-injection waveforms 4 and 5A per DO-160F.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered by avalanche breakdown, with symmetrical bidirectional conduction enabling protection against both polarities of transients. Its low RθJC (1.0 °C/W) and void-free UL94V-0 epoxy package support high-reliability mounting on FR4 PCBs using the specified thermal pad layout.
It is characterized for operation across –55°C to +150°C junction temperature, tested per AEC-Q101, and qualified for MIL-PRF-19500 upscreening options. Standby current ID is ≤10 μA at VWM, and clamping response time is <5 ns - critical for suppressing fast-rising ESD and RFI-induced transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - enables single-device suppression of severe lightning-induced surges without cascading failure |
| Reverse Standoff Voltage (VWM) | 110 V - sets maximum continuous operating voltage before clamping initiates, matching 96–110 V DC bus systems |
| Clamping Voltage (VC) | ≤177 V @ IPP = 204 A - defines protected circuit's maximum transient overvoltage during worst-case surge |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - allows efficient heat transfer to heatsink or copper pour, sustaining repeated surge events |
| Standby Current (ID) | ≤10 μA @ 110 V - ensures negligible leakage power loss in always-on avionics and vehicle control modules |
| Response Time | <5 ns - provides sub-nanosecond turn-on for ESD and fast-switching noise suppression |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - eliminates dry-pack requirement and simplifies SMT assembly logistics |
Pinout & Package
MAPLAD36KP110CAE3 uses a surface-mount PLAD package (void-free thermosetting epoxy, UL94V-0 rated) with metal base cathode contact. Dimensions: 12.32 × 10.54 × 5.08 mm (L × W × H), weight ≈1.85 g. Mounting requires recommended thermal pad layout per datasheet Figure 6.

IC Role / Device Role / Timing Role: Primary surge clamp across battery rail, absorbing up to 36 kW energy without degradation over 1000+ cycles. Use Value: Maintains VWM = 110 V to avoid false triggering during normal 14–16 V battery operation while clamping to safe levels during 120 V transients. |
| Industrial Motor Drive I/O Protection | Railway Signaling Interface Protection |
Use Scenario: Shielding encoder feedback lines and analog sensor inputs in variable-frequency drives exposed to switching noise and ground bounce. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed at PCB edge connectors to suppress coupled RFI and EFT bursts (IEC 61000-4-4). Use Value: Sub-5 ns response and ≤10 μA standby current prevent signal distortion and power waste in precision position feedback loops. | Use Scenario: Securing track-side signaling equipment (e.g., axle counters, interlocking relays) against induced surges from nearby lightning or traction return currents. IC Role / Device Role / Timing Role: Secondary lightning protector installed upstream of isolation barriers per EN 50121-4, rated for Class 5 (42 Ω source). Use Value: Validated for 4 kV surge with long-distance coupling - ensures fail-safe operation in safety-critical railway infrastructure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | 600 W PPP rating, SMB package, RθJC ≈ 35 °C/W | Limited to lower-energy transients; unsuitable for DO-160 Section 22 or IEC 61000-4-5 Class 5 | Select only for cost-sensitive industrial controls where 36 kW surge immunity is not required. |
| SMCJ110CA | 1500 W PPP rating, SMC package, RθJC ≈ 12 °C/W | Supports moderate automotive load dump but lacks DO-160F waveform validation and MIL-PRF-19500 screening options | Use when AEC-Q101 qualification is needed but full aerospace-grade surge margin is unnecessary. |
Compared with SMBJ110CA and SMCJ110CA, MAPLAD36KP110CAE3 delivers 24× and 24× higher peak pulse power respectively, with validated DO-160F compliance and lower thermal resistance - making it the only option for certified avionics and mission-critical vehicle systems requiring multi-stroke lightning resilience.

FAQ
What is the clamping voltage of MAPLAD36KP110CAE3 at its rated peak pulse current?
The MAPLAD36KP110CAE3 has a maximum clamping voltage (VC) of 177 V at its rated peak pulse current (IPP) of 204 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 safe overvoltage thresholds during surge events. The MAPLAD36KP110CAE3 maintains this clamping performance across its full operating temperature range of –55°C to +150°C.
Is MAPLAD36KP110CAE3 suitable for use in automotive applications requiring AEC-Q101 qualification?
Yes, MAPLAD36KP110CAE3 is tested and qualified to AEC-Q101 standards for discrete semiconductors, including temperature cycling, mechanical shock, and humidity testing. Its bidirectional construction, 110 V standoff, and 36 kW surge capability make it appropriate for automotive load dump and ESD protection in engine control units and ADAS modules. The MAPLAD36KP110CAE3 also supports optional MIL-PRF-19500 upscreening for extended reliability requirements.
Does MAPLAD36KP110CAE3 require special PCB layout considerations?
Yes, MAPLAD36KP110CAE3 requires adherence to the manufacturer-specified pad layout (Ref. A = 11.94 mm, B = 5.85 mm) to ensure optimal thermal dissipation and surge current handling. The metal base must be soldered to a large copper pour or heatsink area to leverage its 1.0 °C/W junction-to-case thermal resistance. Deviation from the recommended footprint risks thermal runaway during repetitive surges. The MAPLAD36KP110CAE3 datasheet provides exact dimensions and thermal pad guidelines in Figure 6.
What does the 'CA' suffix indicate in MAPLAD36KP110CAE3?
The 'CA' suffix in MAPLAD36KP110CAE3 denotes bidirectional polarity - meaning the device provides symmetrical clamping for both positive and negative transients without requiring orientation during placement. This differs from unidirectional versions (e.g., MAPLAD36KP110AE3), which have anode/cathode asymmetry and require correct PCB orientation. The MAPLAD36KP110CAE3's bidirectional behavior is intrinsic to its internal structure and verified per IEC 61000-4-5 and DO-160F test protocols.
How does MAPLAD36KP110CAE3 perform under RTCA DO-160F lightning-induced transient testing?
MAPLAD36KP110CAE3 is validated for RTCA DO-160F Section 22 multi-stroke lightning testing, specifically supporting Pin Injection Waveform 4 (6.4/69 μs) at Level 5 and Waveform 5A (40/120 μs) at Level 4. Its 36 kW rating and <5 ns response enable reliable clamping during sequential surges. The MAPLAD36KP110CAE3 achieves this performance with no degradation across 1000+ surge cycles when mounted per spec - a requirement for certified avionics installations.
