Product details
Overview
MAPLAD36KP130A from Microsemi is a unidirectional 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, clamps at ≤209 V under 100 A peak impulse current, and features a 130 V reverse standoff voltage (VWM) with 144–159 V breakdown range (VBR). Its low-profile thermoset epoxy package enables robust lightning protection per RTCA DO-160 Section 22 and IEC 61000-4-5 Class 4 (2 Ω source).
For engineers reviewing the MAPLAD36KP130A datasheet, MAPLAD36KP130A pinout, MAPLAD36KP130A application, or MAPLAD36KP130A equivalent, key selection criteria include its 130 V VWM, 209 V max clamping voltage at 100 A, 1.0 °C/W junction-to-case thermal resistance, RoHS-compliant e3 plating, and verified compliance with AEC-Q101 and MIL-PRF-19500 screening options.
Technical Context
The MAPLAD36KP130A employs an avalanche diode structure optimized for multi-stroke lightning transients, with thermal design enabling sustained energy dissipation via metal-base cathode mounting. Its 1.0 °C/W RθJC supports direct heatsink coupling on FR4 PCBs using the specified pad layout, and it meets RTCA DO-160F Waveform 4 (6.4/69 μs) Level 4 and Waveform 5A (40/120 μs) Level 4 requirements at 25°C.
It operates across –55°C to +150°C junction temperature, exhibits <100 ps response time from 0 V to VBR(min), and maintains ≤10 μA standby current at rated VWM. The device is validated for secondary lightning protection per IEC 61000-4-5 with 2 Ω, 12 Ω, and 42 Ω source impedances - specifically supporting Class 4 at 2 Ω with VWM = 130 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains aircraft-grade lightning surges without failure |
| Reverse Standoff Voltage (VWM) | 130 V - sets maximum continuous operating voltage before conduction begins |
| Breakdown Voltage (VBR) | 144–159 V @ 5 mA - defines precise avalanche initiation threshold for predictable clamping onset |
| Max Clamping Voltage (VC) | 209 V @ 100 A - limits downstream circuit voltage during worst-case surge events |

| Junction Temp Range | –55°C to +150°C - certified for engine bay, flight control, and harsh-environment deployment |
Pinout & Package
The MAPLAD36KP130A uses a void-free transfer-molded thermosetting epoxy package (UL94V-0) with tin-lead or RoHS-compliant matte-tin plating. Cathode is the metal base (bottom side); anode is top-side metallization. Package dimensions: 12.32–12.57 mm (A1) × 10.54–10.80 mm (A2) × 3.68–3.94 mm (B), weight ≈1.7–2.0 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Cathode | Primary heat path and return node; must be soldered to thermal pad for RθJC = 1.0 °C/W performance |
| Top Metallization | Anode | Transient current entry point; connects to protected line (e.g., 28 V DC bus or sensor input) |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Lower PPP (600 W), smaller SMB package, RθJC = 15 °C/W | Not suitable for DO-160 multi-stroke or IEC 61000-4-5 Class 4; limited to consumer/industrial single-event surges | Select only for cost-sensitive, low-energy applications where 36 kW capability is unnecessary |
| SMCJ130A | Higher PPP (1500 W), SMC package, RθJC = 3.5 °C/W, no AEC-Q101 or DO-160 validation | Lacks aerospace qualification and thermal performance for repeated surges; requires larger PCB area than PLAD | Acceptable for non-certified industrial systems needing >1 kW but not full 36 kW capability |
Compared with SMBJ130A and SMCJ130A, the MAPLAD36KP130A provides 60× and 24× higher peak pulse power respectively, validated thermal path for heatsink mounting, and formal qualification for aviation and automotive safety-critical surge standards - making it irreplaceable in certified high-reliability platforms.

FAQ
What is the maximum clamping voltage of the MAPLAD36KP130A at its rated peak pulse current?
The MAPLAD36KP130A has a maximum clamping voltage (VC) of 209 V at 100 A peak pulse current under 10/1000 μs waveform conditions. This value is guaranteed per the manufacturer's electrical characteristics table and ensures protected circuits remain below critical overvoltage thresholds during standardized surge events.
Is the MAPLAD36KP130A qualified for automotive applications?
Yes, the MAPLAD36KP130A is AEC-Q101 qualified and validated for automotive load-dump protection per ISO 7637-2. Its 130 V VWM, 209 V clamping, and thermal performance make it suitable for 24/28 V systems in ECUs, ADAS modules, and body control units requiring high-reliability surge immunity.
Does the MAPLAD36KP130A require dry packing or moisture barrier bags?
No, the MAPLAD36KP130A has IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1 rating, meaning it does not require dry packing, baking, or floor-life controls. It can be stored and processed like standard surface-mount components without special humidity handling.
How is thermal management implemented for the MAPLAD36KP130A in high-duty-cycle applications?
The MAPLAD36KP130A achieves 1.0 °C/W junction-to-case thermal resistance by routing heat through its metal-base cathode into a dedicated thermal pad on the PCB. Mounting per the specified pad layout (Ref. A=11.94 mm, B=5.85 mm) and optional heatsink contact is essential to maintain performance during repetitive 10/1000 μs surges.
Can the MAPLAD36KP130A be used for bidirectional transient suppression?
No, the MAPLAD36KP130A is unidirectional. For bidirectional operation, Microsemi offers the MAPLAD36KP130CA variant (with CA suffix), which provides symmetrical clamping for AC-coupled or floating signal lines. Using the unidirectional MAPLAD36KP130A in bidirectional configurations risks reverse-bias breakdown and failure.
