Product details
Overview
MXPLAD36KP36CA 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 at ≤58.1 V under 620 A peak impulse current, and features 36 V reverse standoff voltage (VWM) with ±5% breakdown tolerance. It is qualified to AEC-Q101 and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MXPLAD36KP36CA datasheet, MXPLAD36KP36CA pinout, MXPLAD36KP36CA application, or MXPLAD36KP36CA equivalent, this device is selected for secondary lightning protection per IEC 61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), pin-injection immunity per RTCA/DO-160F Waveform 4 (Level 4 up to 400 V), and ESD/EFT compliance per IEC 61000-4-2/4-4.
Technical Context
This TVS diode operates as a voltage-clamped crowbar during transients, leveraging silicon avalanche structure to respond in <5 ns. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal lines, and its low RθJC of 1.0 °C/W supports thermal management on FR4 PCBs with recommended pad layout.
It is rated for junction temperatures from –55°C to +150°C, exhibits a temperature coefficient of breakdown voltage (αVBR) of +38 mV/°C, and maintains ≤10 μA standby current at VWM, ensuring minimal leakage in always-on protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains full-rated surge energy without failure in lightning or load-dump events |
| Reverse Standoff Voltage (VWM) | 36 V - maximum continuous operating voltage before conduction begins; matches 24 V automotive rail with margin |
| Breakdown Voltage (VBR) | 40.0–44.2 V @ 5 mA - defines precise avalanche initiation threshold for predictable clamping onset |
| Max Clamping Voltage (VC) | 58.1 V @ 620 A - limits downstream voltage stress to safe levels for 3.3 V/5 V/12 V interface ICs |
| Standby Current (ID) | ≤10 μA @ 36 V - negligible quiescent loading on protected circuitry across temperature range |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables effective heat transfer to PCB copper pour or heatsink for repetitive surge handling |
| Surge Standards Compliance | IEC 61000-4-5 (Class 1–5), RTCA DO-160F Waveform 4 Level 4, IEC 61000-4-2/4-4 - validated for aviation-grade immunity |
Pinout & Package
MXPLAD36KP36CA uses a surface-mount PLAD package (void-free UL94V-0 epoxy body) with metal base cathode contact on underside; polarity marking applies only to unidirectional variants - bidirectional devices like MXPLAD36KP36CA have no polarity marking and symmetric terminal function.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Top-side metallization) | Transient current entry point (bidirectional) | Accepts surge current from either direction; connects to line under protection |
| Cathode (Metal base / bottom side) | Transient current return path (bidirectional) | Serves as common reference plane; must be soldered to large copper area for thermal and electrical performance |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Enables protection of AC signals, differential buses, or floating nodes without polarity constraints |
| Low-profile thermally optimized PLAD package | 12.32 × 10.54 × 5.08 mm footprint with 1.0 °C/W RθJC supports high-power dissipation on standard PCBs |
| AEC-Q101 qualification and lot traceability | Validates reliability for automotive under-hood applications and enables failure root-cause analysis |
| RTCA DO-160 Section 22 multi-stroke lightning compliance | Guarantees survivability across ≥1000 surges at rated energy-critical for avionics longevity |
| Moisture sensitivity level 1 (MSL-1) | Eliminates dry-pack requirement and floor-life limitations, simplifying SMT assembly logistics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | 600 W PPP rating, SMB package, 1.5× higher clamping ratio (VC/VWM = 1.71 vs. 1.61) | Targeted at consumer/industrial designs with lower surge severity; not DO-160F or AEC-Q101 qualified | Select when cost and board space constrain requirements and full 36 kW surge immunity is unnecessary |
| SMCJ36CA | 1500 W PPP, SMC package, RθJC = 2.2 °C/W, same VWM/VC specs but lower energy capacity | Suitable for single-event surge environments (e.g., lab equipment); lacks multi-stroke validation | Choose for non-automotive/non-aviation applications where IEC 61000-4-5 Class 3 is sufficient |

FAQ
What is the clamping voltage of MXPLAD36KP36CA at its rated peak pulse current?
MXPLAD36KP36CA has a maximum clamping voltage (VC) of 58.1 V at 620 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is guaranteed across the operating temperature range and forms the basis for downstream circuit voltage stress analysis. The clamping performance is validated per Figure 3 in the RF01216 datasheet and remains stable over ≥1000 multi-stroke surges.
Is MXPLAD36KP36CA compliant with automotive reliability standards?
Yes, MXPLAD36KP36CA is fully qualified to AEC-Q101 for stress testing including HTGB, HTRB, and temperature cycling. It also supports optional MIL-PRF-19500 upscreening for high-reliability programs. Lot traceability and 3σ screening on standby current (ID) are standard, confirming suitability for under-hood automotive ECUs and ADAS power modules.
Does MXPLAD36KP36CA require special PCB layout considerations?
Yes-MXPLAD36KP36CA requires adherence to the recommended pad layout (Ref. A=0.470", B=0.230", C=0.100") and connection of its metal base (cathode) to a minimum 1.5 cm² copper pour for thermal dissipation. Trace inductance must be minimized: keep leads short and wide, avoid vias between device and ground plane, and place it directly at the protected port entry point.
Can MXPLAD36KP36CA be used for bidirectional signal line protection?
Yes-MXPLAD36KP36CA is explicitly a bidirectional TVS (denoted by "CA" suffix) and provides symmetrical clamping for AC-coupled interfaces such as RS-485, CAN FD, or Ethernet PHY lines. Its <5 ns response time and matched positive/negative VC ensure balanced protection without polarity concerns or additional external components.
What is the moisture sensitivity level (MSL) rating for MXPLAD36KP36CA?
MXPLAD36KP36CA is rated MSL-1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and does not require dry pack or baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates moisture-related popcorning risk during standard lead-free reflow profiles up to 260°C peak.
