Product details
Overview
MAPLAD36KP200A from Microsemi is a unidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace and automotive power systems. It delivers 36,000 W peak pulse power at 10/1000 μs, clamps at ≤322 V under 112 A peak impulse current, and features a 200 V reverse standoff voltage (VWM) with 222–245 V breakdown range (V(BR)). It meets RTCA DO-160 Section 22 multi-stroke lightning requirements and IEC 61000-4-5 Class 4 secondary lightning protection with 12 Ω source impedance.
For engineers reviewing the MAPLAD36KP200A datasheet, MAPLAD36KP200A pinout, MAPLAD36KP200A application, or MAPLAD36KP200A equivalent, key selection criteria include its 200 V VWM rating, 322 V max clamping voltage at 112 A, thermal resistance of 1.0 °C/W junction-to-case, RoHS-compliant e3 plating, and qualification per AEC-Q101 and MIL-PRF-19500 screening options.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating when transient voltage exceeds its 200 V standoff threshold. Its silicon avalanche structure provides sub-100 ps response time and low dynamic impedance to limit overvoltage during fast transients like lightning-induced surges or load dump events.
It is rated for 36 kW peak pulse power under standardized 10/1000 μs waveform, with thermal design optimized via metal-base cathode construction and 1.0 °C/W RθJC. Derating applies above 100 °C case temperature, and steady-state dissipation is limited to 71 W at TC = 100 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - enables robust protection against aircraft lightning strikes and automotive load dump transients |
| Reverse Standoff Voltage (VWM) | 200 V - maximum continuous operating voltage before clamping initiates; matches 24/28 V DC bus systems with safety margin |
| Breakdown Voltage (V(BR)) | 222–245 V @ 5 mA - defines precise conduction onset; ensures reliable turn-on without premature leakage |
| Max Clamping Voltage (VC) | 322 V @ 112 A IPP - limits downstream voltage stress to safe levels for 200 V-rated components |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - supports high-power dissipation when mounted on heatsinked PCB pads per recommended layout |
| Steady-State Power Dissipation | 71 W @ TC = 100 °C - allows sustained operation under elevated ambient conditions with active thermal management |
| Surge Current Rating (IPP) | 112 A @ 10/1000 μs - quantifies single-event energy-handling capability aligned with IEC 61000-4-5 test profiles |
Pinout & Package
MAPLAD36KP200A uses a surface-mount PLAD package with metal base cathode configuration. The cathode is the exposed metal underside of the device body; the anode is the top-side metallized terminal. Package dimensions: 12.32 × 10.54 × 5.08 mm (L × W × H), with void-free UL94V-0 epoxy body and annealed matte-tin (e3) RoHS-compliant plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (top metallization) | Positive input terminal for unidirectional clamping path | Connects to protected line; conducts surge current toward cathode during overvoltage event |
| Cathode (metal base) | Reference/ground return path | Must be soldered to large copper pad or heatsink for thermal and electrical performance; defines polarity orientation |
Key Features
| Feature | Design Value |

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 SMAJ200A | Lower PPP rating (400 W), smaller SMC package, 200 V VWM, 324 V VC @ 1.2 A IPP | Only suitable for low-energy ESD/EFT; cannot meet DO-160 lightning or load dump requirements | Select MAPLAD36KP200A when 36 kW surge handling and aerospace qualification are required. |
| Vishay V200MLA0603NH | MLA varistor with 200 V RMS, 300 J energy rating, no specified PPP, slower response (>50 ns) | Used for slower AC line surges; lacks AEC-Q101 or DO-160 validation and precise clamping control | Choose MAPLAD36KP200A for fast, repeatable clamping in DC power rails where timing and precision matter. |
Compared with SMAJ200A and V200MLA0603NH, MAPLAD36KP200A uniquely combines 36 kW pulse power, sub-100 ps response, AEC-Q101 qualification, and DO-160 compliance-making it irreplaceable for high-reliability DC bus protection where energy, speed, and certification converge.

FAQ
What is the clamping voltage of MAPLAD36KP200A at its rated peak pulse current?
The MAPLAD36KP200A exhibits a maximum clamping voltage (VC) of 322 V at its rated peak pulse current (IPP) of 112 A under 10/1000 μs waveform conditions. This value is measured per standard test methods and ensures downstream components see controlled overvoltage during surge events. The clamping behavior is consistent across production lots due to tight V(BR) tolerance (222–245 V) and low dynamic impedance.
Is MAPLAD36KP200A qualified for automotive applications?
Yes, MAPLAD36KP200A is qualified to AEC-Q101 for stress testing including temperature cycling, humidity, and mechanical shock. It is widely deployed in 24 V automotive systems for load dump protection, particularly in commercial vehicle ECUs and ADAS power supplies. Its 200 V VWM and 322 V clamping align with ISO 7637-2 Pulse 5a requirements for 24 V nominal systems.
Does MAPLAD36KP200A have RoHS-compliant packaging?
Yes, MAPLAD36KP200A is offered in RoHS-compliant version marked with "e3" in its nomenclature, indicating annealed matte-tin plating that meets JEDEC/IPC standards for lead-free assembly. The device uses UL94V-0 epoxy molding compound and requires no dry pack per IPC/JEDEC J-STD-020B Level 1 moisture sensitivity classification.
How is thermal management implemented for MAPLAD36KP200A in high-power operation?
MAPLAD36KP200A relies on its metal-base cathode for thermal conduction; optimal performance requires mounting on a minimum 11.94 × 5.85 mm copper pad per recommended layout, with optional heatsinking. Its 1.0 °C/W junction-to-case thermal resistance enables 71 W steady-state dissipation at TC = 100 °C, but pulsed operation demands attention to duty cycle derating per Figure 3 in the datasheet.
Can MAPLAD36KP200A be used for bidirectional surge protection?
No, MAPLAD36KP200A is unidirectional only. For bidirectional protection at 200 V standoff, the correct variant is MAPLAD36KP200CA. The "A" suffix denotes unidirectional construction with cathode on the metal base; the "CA" suffix indicates bidirectional symmetry and different marking/polarity conventions. Substituting MAPLAD36KP200A in bidirectional circuits will result in forward conduction and failure.
