Product details
Overview
MAPLAD36KP60CAE3 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, clamps transients to ≤96.8 V at 372 A, and operates with 60 V reverse standoff voltage (VWM). Its low-profile thermoset epoxy package enables robust lightning protection per RTCA DO-160 Section 22 and IEC 61000-4-5 Class 4/5.
For engineers reviewing the MAPLAD36KP60CAE3 datasheet, MAPLAD36KP60CAE3 pinout, MAPLAD36KP60CAE3 application, or MAPLAD36KP60CAE3 equivalent, this device is selected for secondary lightning protection, load dump suppression, and ESD/EFT hardening where bidirectional clamping, high PPP, and thermal reliability are critical design requirements.
Technical Context
This TVS diode uses silicon avalanche junction technology optimized for multi-stroke surge endurance. Its bidirectional construction provides symmetrical clamping for AC-coupled or floating signal/power lines, and its 1.0 °C/W junction-to-case thermal resistance supports mounting on heatsinks for sustained duty cycles.
It meets AEC-Q101 stress testing and supports MIL-PRF-19500 upscreening options. The device is rated for -55°C to +150°C operation, with moisture sensitivity level 1 and RoHS-compliant matte-tin plating per MIL-STD-750 Method 2026.
Key Specifications

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 | 600 W PPP rating, SMB package, 1.5× higher clamping ratio (VC/VWM = 1.75 vs. 1.61) | Limited to single-stroke surges; not qualified for RTCA DO-160 or AEC-Q101 | Select when cost-sensitive consumer-grade protection suffices and multi-stroke endurance is unnecessary |
| SMCJ60CA | 1500 W PPP rating, SMC package, 1.4× higher clamping ratio (VC/VWM = 1.70), RθJC = 2.5 °C/W | Not validated for DO-160 Waveform 5A or IEC 61000-4-5 Class 5; lower thermal performance | Choose for industrial controls requiring moderate surge margin but no aerospace certification |
Compared with SMBJ60CA and SMCJ60CA, MAPLAD36KP60CAE3 delivers 24× and 24× higher peak pulse power respectively, with certified multi-stroke endurance, lower clamping voltage ratio, and superior thermal management-making it the only option for certified aerospace and high-reliability automotive systems.

FAQ
What is the clamping voltage of MAPLAD36KP60CAE3 at its rated peak pulse current?
The MAPLAD36KP60CAE3 has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPP) of 372 A under 10/1000 μs waveform conditions. This value is guaranteed per the manufacturer's electrical characteristics table and reflects worst-case performance across temperature and lot variations. The clamping voltage ensures protected circuits remain below critical overvoltage thresholds during surge events.
Is MAPLAD36KP60CAE3 certified for RTCA DO-160 lightning testing?
Yes, MAPLAD36KP60CAE3 is explicitly validated for RTCA DO-160F Section 22 lightning-induced transient testing. It achieves Level 4 for Waveform 4 (6.4/69 μs) and Level 5 for Waveform 5A (40/120 μs) at 60 V VWM. Certification data is documented in Microsemi Application Note RF01216 Rev B, confirming multi-stroke capability essential for avionics deployment.
Does MAPLAD36KP60CAE3 require a heatsink for standard operation?
MAPLAD36KP60CAE3 does not require an external heatsink for single-pulse or low-duty-cycle surge events, thanks to its 1.0 °C/W junction-to-case thermal resistance and low-profile metal-base package. However, for repetitive surges exceeding 0.05% duty factor or steady-state power >2.5 W, thermal management via PCB copper area or heatsink attachment to the metal base is recommended per Figure 3 derating curve.
What is the meaning of the 'CA' and 'E3' suffixes in MAPLAD36KP60CAE3?
In MAPLAD36KP60CAE3, 'CA' denotes bidirectional polarity construction, and 'E3' specifies RoHS-compliant annealed matte-tin plating per JEDEC J-STD-020B. These suffixes are defined in the Microsemi nomenclature guide: CA confirms symmetrical clamping behavior, while E3 guarantees lead-free finish and Level 1 moisture sensitivity-enabling compatibility with standard Pb-free reflow processes without dry-pack requirements.
How does MAPLAD36KP60CAE3 compare to unidirectional versions like MAPLAD36KP60AE3?
MAPLAD36KP60CAE3 provides symmetrical clamping for AC or floating DC applications, whereas MAPLAD36KP60AE3 offers unidirectional protection with cathode on the metal base. The bidirectional version eliminates polarity installation concerns but exhibits slightly higher leakage at VWM. Both share identical PPP (36 kW), thermal specs, and certifications-but only the CA variant supports differential bus or transformer-coupled interface protection without additional diodes.
