Product details
Overview
MPLAD36KP60CA 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 impulse current (IPP), and operates across –55°C to +150°C junction temperature. It is qualified to AEC-Q101 and meets RTCA DO-160F Waveform 4 Level 4 and IEC 61000-4-5 Class 4 (42 Ω source) requirements.
For engineers reviewing the MPLAD36KP60CA datasheet, MPLAD36KP60CA pinout, MPLAD36KP60CA application, or MPLAD36KP60CA equivalent, this device is selected for secondary lightning protection, load dump suppression, and ESD/EFT hardening where low-profile SMT mounting, traceable high-reliability screening, and multi-stroke surge endurance are required.
Technical Context
The MPLAD36KP60CA employs a silicon avalanche diode structure optimized for fast response (<5 ns clamping time) and low thermal resistance (RθJC = 1.0 °C/W). Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal/power lines without polarity concerns.
It is rated for 36,000 W peak pulse power under 10/1000 μs waveform with full surge testing per IEC 61000-4-2/4-4/4-5 and RTCA DO-160F, and supports MIL-PRF-19500 upscreening options including 3σ lot norm screening on standby current (ID).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | Lower PPP (600 W), smaller SMB package, higher RθJA (50 °C/W), no AEC-Q101 or DO-160 qualification | Suitable only for low-energy consumer-grade ESD protection - not for multi-stroke lightning or automotive load dump | Select only for cost-sensitive, non-safety-critical designs with <100 A surge exposure |
| SMCJ60CA | Higher PPP (1500 W), larger SMC package, RθJC ≈ 2.5 °C/W, AEC-Q101 qualified but no DO-160 data | Valid for automotive ECU front-end protection but lacks RTCA DO-160F certification and 36 kW capability | Use where DO-160 compliance is not required and peak current stays below 150 A |
Compared with SMBJ60CA and SMCJ60CA, the MPLAD36KP60CA provides 24× and 24× higher peak pulse power respectively, certified DO-160F performance, and a thermally optimized metal-base package enabling reliable operation under repetitive 372 A surges - making it the only option for certified aerospace and heavy-duty automotive secondary protection.

FAQ
What is the clamping voltage of the MPLAD36KP60CA at its rated peak pulse current?
The MPLAD36KP60CA has a maximum clamping voltage (VC) of 96.8 V when subjected to its rated peak pulse current of 372 A under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream components remain within safe voltage limits during surge events. The MPLAD36KP60CA achieves this with sub-5 ns response time and low dynamic impedance.
Is the MPLAD36KP60CA qualified for automotive applications?
Yes, the MPLAD36KP60CA is AEC-Q101 qualified and explicitly rated for automotive load dump protection. Its 60 V standoff voltage, 372 A peak current handling, and thermal design (RθJC = 1.0 °C/W) make it suitable for 24 V system front-end protection in commercial vehicles and off-highway equipment. The MPLAD36KP60CA also supports optional MIL-PRF-19500 upscreening for extended reliability validation.
Does the MPLAD36KP60CA meet RTCA DO-160F lightning test requirements?
Yes, the MPLAD36KP60CA meets RTCA DO-160F Section 22 for multi-stroke lightning simulation, specifically Waveform 4 (6.4/69 μs) Level 4 up to 300 V standoff variants and Waveform 5A (40/120 μs) Level 4 up to 78 V standoff variants. As a bidirectional device, the MPLAD36KP60CA provides symmetrical protection essential for avionics signal integrity and power rail stability.
How should the metal base of the MPLAD36KP60CA be mounted for optimal thermal performance?
The metal base of the MPLAD36KP60CA serves as both the cathode terminal and primary thermal path. For optimal thermal performance, it must be soldered directly to a minimum 100 mm² copper pour with ≥6 thermal vias (0.3 mm diameter) connecting to inner ground/power planes. This achieves the specified RθJC of 1.0 °C/W and prevents thermal runaway during repetitive 372 A surges. The MPLAD36KP60CA pad layout is defined in Microsemi RF01216 Rev B.
What is the moisture sensitivity level (MSL) rating for the MPLAD36KP60CA?
The MPLAD36KP60CA is rated MSL Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and requires no dry pack or baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates moisture-related popcorning risks during assembly. The MPLAD36KP60CA's void-free epoxy encapsulation and annealed matte-tin plating contribute to this robust MSL classification.
