Product details
Overview
MAPLAD36KP260CA 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) with ±5% breakdown tolerance (289–320 V). It meets RTCA DO-160 Section 22 multi-stroke lightning requirements and IEC 61000-4-5 Class 3/4 secondary lightning protection with 2 Ω and 42 Ω source impedances.
For engineers reviewing the MAPLAD36KP260CA datasheet, MAPLAD36KP260CA pinout, MAPLAD36KP260CA application, or MAPLAD36KP260CA equivalent, key selection criteria include its bidirectional polarity, 260 V VWM rating, 419 V max clamping voltage at 86 A, thermal resistance of 1.0 °C/W junction-to-case, and qualification to AEC-Q101 and MIL-PRF-19500 screening levels.
Technical Context
This TVS diode employs an avalanche breakdown mechanism optimized for fast response (<5 ns clamping time) and low thermal resistance. Its void-free transfer-molded thermosetting epoxy package enables direct metal-base heat sinking, supporting continuous operation up to +150 °C junction temperature.
It is characterized for bidirectional conduction with symmetrical clamping behavior, validated per IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and RTCA/DO-160F Waveform 4 & 5A pin-injection testing. Standby leakage is limited to 10 μA at 260 V VWM, ensuring minimal system loading during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 260 V - Maximum continuous operating voltage before clamping begins; matches 220–240 VAC-derived DC rails or 28 V automotive load-dump envelopes. |
| V(BR) min/max | 289–320 V - Breakdown occurs within this range at 5 mA; ensures reliable turn-on margin above VWM without premature conduction. |
| VC @ IPP | 419 V max at 86 A - Clamping voltage under 10/1000 μs surge; defines maximum stress imposed on protected downstream circuitry. |
| PPP | 36,000 W - Peak pulse power handling capability; enables single-device protection against severe lightning-induced transients. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; allows efficient heat transfer to PCB copper or external heatsink for sustained multi-pulse operation. |
| ID @ VWM | 10 μA max - Standby leakage current at rated standoff voltage; negligible power loss and signal integrity impact in high-impedance circuits. |
| TJ/TSTG | −55 to +150 °C - Operating and storage temperature range; supports deployment in avionics bays, engine compartments, and industrial control enclosures. |
Pinout & Package
MAPLAD36KP260CA uses a PLAD (Power Leadless Array Device) surface-mount package with two terminals: anode and cathode formed on opposite sides of the metal base. The device is bidirectional; polarity marking is not applied. Thermal performance relies on soldering the metal base directly to a large copper pad per recommended layout (A = 0.470", B = 0.230", C = 0.100").
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Common Terminal (Bidirectional Anode/Cathode) | Serves as both current path and primary thermal interface; must be soldered to ≥1 in² copper area for RθJA ≤ 50 °C/W. |
| Top Surface Pad | Common Terminal (Bidirectional Anode/Cathode) | Completes bidirectional conduction path; symmetric layout eliminates orientation dependency during placement. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional surge suppression | Enables protection of AC-coupled or floating signal lines without polarity constraints; eliminates need for dual unidirectional devices. |
| AEC-Q101 qualified | Validated for automotive under-hood applications including alternator load dump and ISO 7637-2 pulse 5a/b compliance. |
| RTCA DO-160F Section 22 compliant | Passes multi-stroke lightning test (Waveform 4 & 5A) up to Level 5 for long-distance configurations - critical for aircraft power distribution units. |
| Moisture Sensitivity Level 1 | No dry-pack or baking required prior to reflow; simplifies SMT line logistics and reduces manufacturing cost. |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring M, MA, MX, or MXL screening levels - traceable wafer lots and 3σ ID screening included. |
Applications
| Aircraft Power Distribution Units | Automotive Engine Control Modules |

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 SMAJ260CA | Lower PPP (400 W), smaller SMA package, 260 V VWM, 428 V VC @ 93.5 A | Rated for consumer/industrial use only; not qualified to AEC-Q101 or DO-160F | Select when cost and board space are prioritized over aerospace/automotive qualification and multi-stroke endurance. |
| Vishay V260CH8 | Same 260 V VWM and bidirectional construction; 30 kW PPP, 424 V VC @ 71.4 A, TO-277 package | Higher RθJA (60 °C/W); requires larger thermal pad; no DO-160F or MIL-PRF-19500 screening options | Choose where legacy TO-277 footprint compatibility is required and 36 kW rating is not mandatory. |

FAQ
What is the clamping voltage of MAPLAD36KP260CA under standard 10/1000 μs surge conditions?
The MAPLAD36KP260CA has a maximum clamping voltage (VC) of 419 V at 86 A peak pulse current 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.
Is MAPLAD36KP260CA suitable for automotive applications requiring AEC-Q101 qualification?
Yes, MAPLAD36KP260CA is tested and qualified to AEC-Q101 standards for discrete semiconductors. It undergoes stress testing including HTGB, HTRB, and temperature cycling, and supports automotive use cases such as alternator load dump protection and ECU power rail hardening.
Does MAPLAD36KP260CA require moisture sensitivity handling before reflow soldering?
No, MAPLAD36KP260CA is rated Moisture Sensitivity Level 1 (MSL-1) per IPC/JEDEC J-STD-020B. It does not require dry packing or baking prior to surface-mount reflow, simplifying manufacturing flow and reducing process risk.
How does the PLAD package of MAPLAD36KP260CA improve thermal performance compared to standard SMB/SMA packages?
The PLAD package uses a metal-base construction with direct thermal path from junction to PCB copper. Its RθJC of 1.0 °C/W and recommended 1 in² thermal pad reduce junction temperature rise by >60% versus SMB packages under identical 36 kW surge conditions, preventing thermal runaway during multi-pulse events.
Can MAPLAD36KP260CA be used for RTCA DO-160F Section 22 lightning protection in aircraft systems?
Yes, MAPLAD36KP260CA is explicitly validated for RTCA DO-160F Section 22 multi-stroke lightning testing. Per the datasheet, it meets Level 5 for long-distance Waveform 4 (6.4/69 μs) and Class 3/4 for IEC 61000-4-5 with 2 Ω and 42 Ω source impedances - fulfilling primary and secondary aircraft surge protection requirements.
