Product details
Overview
MAPLAD36KP260CAE3 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 kW peak pulse power at 10/1000 μs, clamps at ≤419 V under 86 A peak impulse current, and features a 260 V reverse standoff voltage (VWM), 289–320 V breakdown voltage (V(BR)), and 1.0 °C/W junction-to-case thermal resistance.
For engineers reviewing the MAPLAD36KP260CAE3 datasheet, MAPLAD36KP260CAE3 pinout, MAPLAD36KP260CAE3 application, or MAPLAD36KP260CAE3 equivalent, key selection criteria include IEC 61000-4-5 Class 3/4 secondary lightning protection capability with 42 Ω and 12 Ω source impedances, RTCA DO-160F Waveform 4 Level 4/5 pin injection compliance, and RoHS-compliant e3 termination plating.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during transients, leveraging avalanche breakdown to divert surge energy away from sensitive circuitry. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal lines, and its low RθJC (1.0 °C/W) supports high-reliability mounting on thermally optimized PCB pads per recommended layout.
It meets AEC-Q101 stress testing requirements and is qualified for high-reliability screening per MIL-PRF-19500. The device is specified for operation across –55 °C to +150 °C junction temperature and exhibits a ±0.08 %/°C temperature coefficient of breakdown voltage (αV(BR)).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 260 V - Maximum continuous operating voltage before conduction begins; sets minimum system voltage margin for reliable standby isolation. |
| V(BR) min/max | 289–320 V - Breakdown occurs within this range at 5 mA; ensures predictable turn-on threshold across temperature and lot variation. |
| VC @ IPP | 419 V - Maximum clamping voltage at 86 A peak pulse current; defines worst-case overvoltage seen by protected downstream circuitry. |
| PPP | 36,000 W - Peak pulse power handling at 10/1000 μs waveform; enables robust multi-stroke lightning strike resilience per DO-160 Section 22. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; allows direct heatsinking via metal baseplate for sustained surge duty cycles. |
| ID @ VWM | 10 μA - Standby leakage current at rated standoff voltage; negligible power loss and EMI impact in always-on protection circuits. |
| αV(BR) | ±0.08 %/°C - Temperature coefficient of breakdown voltage; ensures stable clamping threshold across full operating temperature range. |
Pinout & Package
MAPLAD36KP260CAE3 uses a surface-mount PLAD package with a metal baseplate serving as the cathode terminal for bidirectional operation. The device has two terminals: anode and cathode, both accessible via solderable terminations on opposite edges of the molded body. Polarity marking is not applied on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during positive transients | Connects to line under protection; forms one side of symmetrical clamping path in bidirectional configuration. |
| Cathode | Current exit point during positive transients; metal baseplate | Must be soldered to large copper pour or heatsink for thermal management and low-inductance surge return path. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ260CA | 600 W PPP rating, 5.0 mm × 3.5 mm SMB package, RθJA = 40 °C/W, no MIL-PRF-19500 screening option | Targeted at commercial industrial controls; insufficient for DO-160F multi-stroke or AEC-Q101 qualification | Select when cost-sensitive, non-mission-critical designs require basic IEC 61000-4-5 Class 2 protection only. |

FAQ
What is the clamping voltage of MAPLAD36KP260CAE3 at its rated peak pulse current?
The MAPLAD36KP260CAE3 has a maximum clamping voltage (VC) of 419 V at its rated peak pulse current (IPP) of 86 A under 10/1000 μs waveform conditions. This value is measured per Figure 3 in the RF01216 datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The clamping ratio (VC/VWM = 1.61) reflects high efficiency for a 260 V standoff device.
Is MAPLAD36KP260CAE3 qualified for automotive applications per AEC-Q101?
Yes, MAPLAD36KP260CAE3 is tested and qualified in accordance with AEC-Q101 requirements for discrete semiconductors. The device undergoes stress testing including HTGB, HTRB, and surge testing per the standard, and its qualification is explicitly stated in the RF01216 datasheet. This makes MAPLAD36KP260CAE3 suitable for under-hood and powertrain applications where high-temperature reliability is mandatory.
Does MAPLAD36KP260CAE3 meet RTCA DO-160F lightning protection standards?
Yes, MAPLAD36KP260CAE3 is validated for RTCA DO-160F Section 22 lightning-induced transient susceptibility, including Waveform 4 (6.4/69 μs) Level 4 and Waveform 5A (40/120 μs) Level 4 compliance. The device is rated for multi-stroke lightning protection and is specifically listed in the datasheet for DO-160F Waveform 4 up to 300 V VWM devices, confirming applicability for MAPLAD36KP260CAE3's 260 V rating.
What is the thermal resistance and recommended mounting method for MAPLAD36KP260CAE3?
MAPLAD36KP260CAE3 has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W. Its metal baseplate serves as the cathode and must be soldered to a large copper pour or external heatsink using the pad layout specified in the RF01216 datasheet. Thermal performance is optimized when mounted on FR4 with the recommended footprint (A = 0.470", B = 0.230") and controlled case temperature.
How does the e3 suffix in MAPLAD36KP260CAE3 affect its assembly process?
The e3 suffix in MAPLAD36KP260CAE3 indicates RoHS-compliant annealed matte-tin plating on all terminations, fully compatible with lead-free reflow soldering processes up to 260 °C for 10 seconds. This plating meets MIL-STD-750 Method 2026 for solderability and eliminates concerns about tin whisker growth or intermetallic embrittlement in long-life deployments.
