Product details
Overview
MAPLAD36KP160CAE3 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 160 V reverse standoff voltage (VWM), clamps to ≤259 V at 10 A IPP, and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP160CAE3 datasheet, MAPLAD36KP160CAE3 pinout, MAPLAD36KP160CAE3 application, or MAPLAD36KP160CAE3 equivalent, this device is evaluated for secondary lightning protection per IEC 61000-4-5 (42 Ω, 12 Ω, 2 Ω source impedances), pin injection immunity per RTCA/DO-160F Waveforms 4 and 5A, and ESD/EFT compliance per IEC 61000-4-2/4-4.
Technical Context
This TVS diode operates in bidirectional mode with symmetrical clamping behavior, enabling protection of AC-coupled or differential signal lines without polarity constraints. Its low thermal resistance (RθJC = 1.0 °C/W) and void-free UL94V-0 epoxy package support high-reliability mounting on FR4 PCBs with recommended pad layout for optimal heat dissipation.
It is characterized for operation across –55 °C to +150 °C junction temperature, with 3σ lot norm screening on standby current (ID), surge-tested per AEC-Q101, and available with MIL-PRF-19500 upscreening options. Clamping response time is <5 ns, and moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 36,000 W @ 10/1000 μs - sustains aircraft-grade lightning surges without failure |
| Reverse Standoff Voltage (VWM) | 160 V - maximum continuous operating voltage before conduction begins |
| Breakdown Voltage (V(BR)) | 178–197 V @ 5 mA - ensures reliable turn-on margin above VWM |
| Max Clamping Voltage (VC) | 259 V @ 10 A IPP - limits downstream voltage stress during surge events |
| Standby Current (ID) | 10 μA @ 160 V - negligible leakage in normal operation |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables efficient heat transfer to heatsink or copper pour |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - supports standard SMT reflow without baking |
Pinout & Package
MAPLAD36KP160CAE3 uses a surface-mount PLAD package (void-free thermosetting epoxy, UL94V-0) with two terminals: anode and cathode. For bidirectional devices, polarity is non-applicable; both terminals are electrically symmetrical. The metal base serves as thermal interface and mechanical anchor.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode (bidirectional symmetry) | One side of symmetrical PN junction pair - connects to protected line or node |
| Terminal 2 | Cathode (bidirectional symmetry) | Other side of symmetrical PN junction pair - connects to reference (GND or return) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC, differential, or floating bus lines without polarity concerns |
| RTCA DO-160F Waveform 4 & 5A compliance | Validated for pin-injection immunity up to Level 5 (Waveform 4: 160 V VWM → 300CA max; Waveform 5A: 160 V VWM → 38CA max) |
| IEC 61000-4-5 secondary lightning protection | Class 1–5 certified with 42 Ω, 12 Ω, and 2 Ω source impedances - covers aircraft and heavy-vehicle subsystems |
| RoHS-compliant (e3 plating) | Tin-lead alternative eliminated; matte-tin terminations ensure solderability per MIL-STD-750 Method 2026 |
| AEC-Q101 qualified | Stress-tested for automotive under-hood environments including temperature cycling, HTRB, and surge endurance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | 600 W PPP rating, SMB package, 10× lower peak power handling | Suitable only for consumer-grade or low-energy industrial I/O - not certified for DO-160 or IEC 61000-4-5 Class 4/5 | Select when cost and board space constrain design and surge threat level is limited to IEC 61000-4-2/4-4 only. |
| SMCJ160CA | 1500 W PPP rating, SMC package, 24× lower peak power vs. MAPLAD36KP160CAE3 | Validated for basic automotive load dump but lacks DO-160F waveform 4/5A certification and multi-stroke endurance data | Choose for cost-sensitive automotive body electronics where full aerospace compliance is not required. |

FAQ
What is the clamping voltage of MAPLAD36KP160CAE3 at its rated peak pulse current?
The MAPLAD36KP160CAE3 has a maximum clamping voltage (VC) of 259 V at 10 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is measured per Figure 3 in RF01216 Rev B and ensures downstream circuitry remains below safe voltage thresholds during high-energy transients.
Is MAPLAD36KP160CAE3 certified for RTCA DO-160F lightning testing?
Yes, MAPLAD36KP160CAE3 is validated for RTCA DO-160F Section 22 multi-stroke lightning testing. It achieves Level 4 for Waveform 4 (6.4/69 μs) and Level 4 for Waveform 5A (40/120 μs) at 160 V VWM, as confirmed in the "Pin injection protection" section of RF01216 Rev B.
Does MAPLAD36KP160CAE3 require special handling due to moisture sensitivity?
No - MAPLAD36KP160CAE3 is rated IPC/JEDEC J-STD-020B Level 1, meaning it has unlimited floor life and does not require dry pack or baking prior to reflow. Its void-free epoxy body and e3 RoHS-compliant terminations support standard SMT assembly processes.
What is the thermal resistance specification for MAPLAD36KP160CAE3, and how does it impact PCB layout?
MAPLAD36KP160CAE3 has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W. This low value requires direct thermal coupling to a heatsink or large copper pour via its metal base. The recommended pad layout (Ref. A=0.470", B=0.230") ensures optimal heat transfer and mechanical stability during thermal cycling.
Can MAPLAD36KP160CAE3 be used in bidirectional AC signal protection applications?
Yes - the "CA" suffix confirms MAPLAD36KP160CAE3 is a bidirectional TVS with symmetrical breakdown and clamping characteristics. It is routinely deployed across AC-coupled data lines (e.g., RS-485, CAN FD), transformer-isolated interfaces, and floating power rails where polarity reversal or differential surge events occur.
