Product details
Overview
MAPLAD36KP260AE3 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, features a 260 V reverse standoff voltage (VWM), clamps transients to ≤419 V at 86 A peak pulse current (IPP), and operates across –55°C to +150°C junction temperature. It is qualified to AEC-Q101 and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP260AE3 datasheet, MAPLAD36KP260AE3 pinout, MAPLAD36KP260AE3 application, or MAPLAD36KP260AE3 equivalent, key selection criteria include its 260 V VWM rating, 419 V max clamping voltage at 86 A, low 1.0 °C/W junction-to-case thermal resistance, RoHS-compliant e3 plating, and suitability for secondary lightning protection per IEC 61000-4-5 with 42 Ω source impedance (Class 3–5).
Technical Context
This TVS diode uses an avalanche breakdown mechanism to divert high-energy transients away from sensitive circuitry. Its void-free UL94V-0 epoxy package and metal-base cathode construction minimize thermal resistance (RθJC = 1.0 °C/W) and support high-reliability mounting on FR4 PCBs with recommended pad layout.
It is characterized for operation under strict impulse conditions: 10/1000 μs waveform, ≤0.05% duty factor, and case temperature control per MIL-STD-750. Standby current ID is ≤10 μA at 260 V, and breakdown voltage V(BR) is specified at 289–320 V with 5 mA test current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 260 V - Maximum continuous operating voltage before clamping begins; matches 220–260 V DC bus or aircraft 235 VAC-derived rails. |
| V(BR) @ 5 mA | 289–320 V - Confirmed avalanche onset range; ensures reliable turn-on margin above VWM. |
| VC @ IPP | 419 V max - Clamping voltage at 86 A peak pulse; defines worst-case voltage seen by protected ICs during surge. |
| PPP @ 10/1000 μs | 36,000 W - Peak pulse power handling; enables compliance with RTCA DO-160F Waveform 4 Level 4/5 and IEC 61000-4-5 Class 5. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; allows direct heatsinking via metal base for sustained multi-pulse operation. |
| ID @ VWM | ≤10 μA - Low leakage at rated standoff; prevents unnecessary power loss in always-on systems like avionics monitoring circuits. |
| Package | PLAD - Surface-mount thermoset epoxy package with metal base cathode; supports automated assembly and high-current solder joint integrity. |
Pinout & Package
MAPLAD36KP260AE3 uses the PLAD package: a low-profile, surface-mount, void-free thermosetting epoxy body with metal base cathode termination. The device has two terminals - anode and cathode - with cathode located on the metal base underside (package bottom), as marked on unidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive input terminal | Connected to protected line (e.g., power rail or signal); current flows into anode during forward conduction or surge clamping. |
| Cathode (metal base) | Negative reference / heat path | Electrically and thermally connected to PCB ground plane; serves as primary thermal dissipation path and circuit return. |
Key Features
| Feature | Design Value |
|---|---|
| 36 kW peak pulse power | Enables single-device protection against severe lightning-induced surges per RTCA DO-160 Section 22 without parallel staging. |
| 1.0 °C/W RθJC | Allows direct thermal coupling to copper pour or heatsink, supporting >100 pulses at 0.05% duty cycle without thermal runaway. |
| AEC-Q101 qualification | Validates robustness for automotive powertrain and chassis electronics under temperature cycling, HTRB, and surge stress. |
| e3 RoHS-compliant plating | Tin-lead-free matte tin plating ensures compatibility with lead-free reflow profiles and long-term solder joint reliability. |
| Moisture sensitivity Level 1 | No dry pack or baking required prior to assembly; eliminates moisture-related popcorning risk during reflow. |
Applications
| Avionics Power Bus Protection | Automotive Load Dump Suppression |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ260A | Lower PPP (600 W), smaller SMB package, RθJC ≈ 40 °C/W | Not suitable for RTCA DO-160 multi-stroke or IEC 61000-4-5 Class 5; limited to low-energy industrial signals | Select only for cost-sensitive, low-surge environments where 36 kW capability is unnecessary. |
| SMCJ260A | PPP = 1500 W, SMC package, RθJC ≈ 10 °C/W, same VWM/V(BR) range | Supports moderate surge duty but fails RTCA DO-160 Section 22 multi-stroke validation; lacks AEC-Q101 qualification | Use where space permits larger SMC footprint and full aerospace compliance is not required. |
Compared with MAPLAD36KP260AE3, SMBJ260A and SMCJ260A offer lower cost and smaller footprints but cannot replicate its 36 kW pulse handling, 1.0 °C/W thermal performance, or certified compliance with RTCA DO-160F Section 22 and AEC-Q101 - making them unsuitable for mission-critical aerospace or automotive power rail protection.

FAQ
What is the maximum clamping voltage of MAPLAD36KP260AE3 under standard 10/1000 μs surge conditions?
The MAPLAD36KP260AE3 has a maximum clamping voltage (VC) of 419 V when subjected to its rated peak pulse current 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 surge events. The MAPLAD36KP260AE3 maintains this clamping performance across its full operating temperature range.
Is MAPLAD36KP260AE3 qualified for automotive applications?
Yes, MAPLAD36KP260AE3 is AEC-Q101 qualified, confirming its reliability for automotive use including engine control units, battery management systems, and ADAS power supplies. It passes stress tests for temperature cycling, high-temperature reverse bias, and surge endurance. The MAPLAD36KP260AE3 is specifically rated for load dump suppression and meets ISO 7637-2 Pulse 5a/b requirements when applied per recommended layout and thermal management guidelines.
Does MAPLAD36KP260AE3 require special handling for moisture sensitivity?
No, MAPLAD36KP260AE3 has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it can be stored indefinitely at ambient conditions without dry packing or baking. This eliminates moisture-related reflow defects such as popcorn cracking. The MAPLAD36KP260AE3's void-free epoxy encapsulation and e3 RoHS-compliant plating contribute to its robust moisture resistance.
How is thermal management implemented for MAPLAD36KP260AE3 in high-duty-cycle applications?
MAPLAD36KP260AE3 achieves effective thermal management through its metal-base cathode structure, delivering a low junction-to-case thermal resistance of 1.0 °C/W. For high-duty-cycle operation, the metal base must be soldered directly to a large copper pour or external heatsink using the recommended pad layout (Ref. A=0.470", B=0.230"). The MAPLAD36KP260AE3's thermal path enables >100 pulses at 0.05% duty factor without exceeding 150°C junction temperature.
What standards does MAPLAD36KP260AE3 meet for lightning protection?
MAPLAD36KP260AE3 meets RTCA DO-160F Section 22 for multi-stroke lightning protection (Waveform 4 and 5A), and IEC 61000-4-5 for secondary lightning immunity with 42 Ω, 12 Ω, and 2 Ω source impedances (Class 3–5). It is validated for Level 4/5 pin injection per DO-160F and Class 5 long-distance coupling per IEC 61000-4-5. These certifications are confirmed in the RF01216 datasheet and apply directly to the MAPLAD36KP260AE3 variant.
