Product details
Overview
MAPLAD36KP60CA from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power systems. It delivers 36 kW peak pulse power at 10/1000 μs, features a 60 V reverse standoff voltage (VWM), clamps to ≤96.8 V at 372 A peak pulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP60CA datasheet, MAPLAD36KP60CA pinout, MAPLAD36KP60CA application, or MAPLAD36KP60CA equivalent, this device is selected for secondary lightning protection per IEC 61000-4-5 (with 2 Ω, 12 Ω, and 42 Ω source impedances), pin-injection immunity per RTCA/DO-160F Waveform 4 & 5A, and ESD/EFT compliance per IEC 61000-4-2/4-4 - all in a low-profile PLAD package with metal-base thermal path.
Technical Context
This bidirectional TVS operates without polarity constraints across AC or differential signal lines, enabling symmetric clamping during positive and negative transients. Its silicon avalanche structure provides sub-5 ns response time and stable breakdown voltage (66.7–73.7 V) with ±72 mV/°C temperature coefficient.
The PLAD package integrates a metal baseplate directly bonded to the die cathode, achieving 1.0 °C/W junction-to-case thermal resistance and enabling high-power dissipation on FR4 PCBs with recommended pad layout. It supports steady-state power up to 71 W at TC = 100°C and passes AEC-Q101 qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains multi-stroke lightning surges without degradation |
| Reverse Standoff Voltage (VWM) | 60 V - maximum continuous operating voltage before clamping initiates |
| Breakdown Voltage (V(BR)) | 66.7–73.7 V @ 5 mA - defines precise conduction threshold under DC stress |
| Clamping Voltage (VC) | ≤96.8 V @ 372 A - limits downstream circuit voltage during worst-case surge |
| Peak Pulse Current (IPP) | 372 A @ 10/1000 μs - quantifies maximum surge current handled at rated PPP |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables direct heatsinking via metal baseplate for thermal reliability |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - no dry pack or bake required prior to reflow |
Pinout & Package
The MAPLAD36KP60CA uses the PLAD (Plastic Low-Profile Avalanche Diode) surface-mount package with a metal baseplate serving as the cathode terminal. Dimensions: 12.32 × 10.54 × 5.08 mm (L × W × H), weight ~1.85 g. Mounting requires thermal pad per datasheet layout (Ref A=11.94 mm, B=5.85 mm).

Use Scenario: Protecting 28 V DC power inputs to flight-critical sensors and actuators against multi-stroke lightning induced on airframe wiring. IC Role / Device Role / Timing Role: Secondary surge protector placed downstream of primary filters, clamping transients before they reach LDOs and microcontrollers. Use Value: Meets RTCA DO-160 Section 22 Level 5 with 60 V standoff, ensuring system-level compliance without adding series impedance or latency. |
Use Scenario: Safeguarding analog sensor inputs (e.g., MAP, TPS) and CAN bus lines in engine compartments exposed to ISO 7637-2 load dump pulses. IC Role / Device Role / Timing Role: Bidirectional TVS shunting fast-rising transients (<5 ns response) while maintaining signal integrity on low-voltage rails. Use Value: Clamps to ≤96.8 V at 372 A, preventing damage to 5 V or 3.3 V ADC front-ends and transceivers during 12 V system surges. |
| Industrial Motor Drive DC Bus Monitoring | Renewable Energy Inverter DC Link Protection |
|
Use Scenario: Shielding voltage-sense circuits monitoring 60 V nominal DC bus in servo drives from switching-induced transients and ground bounce. IC Role / Device Role / Timing Role: High-reliability TVS mounted directly at sense node, leveraging metal baseplate for thermal stability under repeated 10/1000 μs events. Use Value: 36 kW PPP rating ensures survivability across thousands of surge cycles without parameter drift or leakage increase. |
Use Scenario: Protecting MPPT controller inputs connected to photovoltaic string outputs subject to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Bidirectional clamp across +/− PV terminals, suppressing differential-mode surges while meeting IEC 61000-4-5 Class 4 (2 Ω Zs) requirements. Use Value: 60 V VWM aligns with 72 V open-circuit PV strings; clamping <96.8 V prevents overvoltage shutdown of buck converters. |
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 SP3050-060 | 600 W PPP rating, SOD-323 package, 60 V VWM, unidirectional only | Intended for board-level ESD (IEC 61000-4-2), not multi-stroke lightning or high-current surge | Select when protecting low-energy signal lines; insufficient for DO-160 or IEC 61000-4-5 compliance |
| Vishay SMAJ60CA | 600 W PPP, SMA package, 60 V VWM, bidirectional, RθJA = 40 °C/W | Limited to single-stroke surges; fails RTCA DO-160 Section 22 due to thermal mass and power derating | Acceptable for cost-sensitive industrial controls with infrequent transients; not qualified for aerospace or automotive safety-critical use |
Compared with SP3050-060 and SMAJ60CA, the MAPLAD36KP60CA delivers 60× higher peak pulse power, certified multi-stroke endurance, metal-base thermal management, and full DO-160/IEC 61000-4-5 compliance - making it the only viable option for mission-critical aerospace and high-reliability automotive power protection.

FAQ
What is the clamping voltage of MAPLAD36KP60CA at its rated peak pulse current?
The MAPLAD36KP60CA has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current of 372 A under 10/1000 μs waveform conditions. This value is guaranteed across temperature and lot variations per the datasheet's Figure 3 and Electrical Characteristics table, ensuring predictable overvoltage limiting for protected circuitry.
Is MAPLAD36KP60CA suitable for RTCA DO-160 Section 22 Level 5 lightning testing?
Yes, MAPLAD36KP60CA is explicitly validated for RTCA DO-160F Section 22 Level 5 pin-injection testing with Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) at 60 V standoff. The device's 36 kW PPP rating, low thermal resistance, and bidirectional symmetry enable reliable multi-stroke performance required by this standard.
How does the PLAD package of MAPLAD36KP60CA improve thermal performance compared to standard SMC or SMA packages?
The MAPLAD36KP60CA's PLAD package uses a void-free transfer-molded epoxy body with an exposed metal baseplate directly bonded to the die cathode, achieving 1.0 °C/W junction-to-case thermal resistance. This is 10–20× lower than typical SMC/SMA packages, allowing sustained power dissipation and eliminating thermal runaway during repetitive surges.
Does MAPLAD36KP60CA meet AEC-Q101 qualification requirements?
Yes, MAPLAD36KP60CA is tested and qualified to AEC-Q101 standards for discrete semiconductors. This includes stress tests for temperature cycling, humidity bias, mechanical shock, and surge robustness - confirming suitability for automotive underhood applications such as engine control units and battery management systems.
What is the moisture sensitivity level (MSL) for MAPLAD36KP60CA, and does it require baking before reflow?
MAPLAD36KP60CA is rated MSL Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and does not require dry packing or pre-reflow baking. This simplifies manufacturing logistics and eliminates moisture-related popcorning risks during lead-free reflow soldering.
