Product details
Overview
MPLAD18KP130CA from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace and automotive systems. It delivers 18,000 W peak pulse power at 10/1000 μs, features a 130 V reverse standoff voltage (VWM), clamps to ≤209 V at 100 A peak impulse current, and meets RTCA DO-160F Level 5 pin injection and IEC 61000-4-5 Class 2–5 secondary lightning protection requirements.
For engineers reviewing the MPLAD18KP130CA datasheet, MPLAD18KP130CA pinout, MPLAD18KP130CA application, or MPLAD18KP130CA equivalent, this device is selected for high-reliability DC bus and avionics signal line protection where multi-stroke lightning immunity, low thermal resistance (RθJC = 0.7 °C/W), and RoHS-compliant SMT packaging are critical design constraints.
Technical Context
The MPLAD18KP130CA operates as a bidirectional avalanche diode-based TVS, leveraging silicon junction breakdown to clamp transients above its 144–159 V breakdown voltage (V(BR)) range. Its metal-base package enables direct thermal coupling to PCB copper, supporting sustained energy dissipation under repeated 0.05% duty-cycle surges.
It complies with AEC-Q101 stress testing and supports MIL-PRF-19500 upscreening options. The device provides ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and RFI suppression, with clamping response time <5 ns and temperature coefficient of V(BR) at 157 mV/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 18,000 W @ 10/1000 μs - sustains aircraft lightning-induced surges without failure |
| Reverse Standoff Voltage (VWM) | 130 V - maximum continuous DC or peak AC voltage before clamping initiates |
| Breakdown Voltage (V(BR)) | 144–159 V @ I(BR) - defines precise avalanche onset threshold for predictable protection margin |
| Max Clamping Voltage (VC) | 209 V @ 100 A IPP - limits downstream component stress during worst-case surge events |
| Junction-to-Case Thermal Resistance | 0.7 °C/W - enables efficient heat transfer to heatsink or copper pour for thermal reliability |
| Standby Current (ID) | 10 μA @ VWM - ensures negligible leakage in always-on 130 V DC systems |
| Temperature Coefficient αV(BR) | 157 mV/°C - quantifies V(BR) drift over operating temperature for derating calculations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | 600 W PPP rating, 5.0 mm × 4.5 mm SMB package, RθJC = 15 °C/W | Not suitable for DO-160F Level 5 or multi-stroke lightning; limited to consumer/industrial single-event surges | Select when cost and board space constrain requirements, and surge energy remains below 1 kA (10/1000 μs) |
| SMCJ130CA | 1500 W PPP rating, 7.1 mm × 6.2 mm SMC package, RθJC = 3.5 °C/W | Lacks RTCA DO-160F validation and AEC-Q101 qualification; not rated for Class 4/5 lightning | Choose for higher-power industrial use cases where full aerospace certification is unnecessary but 1.5 kW surge handling is required |
Compared with SMBJ130CA and SMCJ130CA, the MPLAD18KP130CA delivers 30× and 12× higher peak pulse power respectively, with validated aerospace-grade reliability, lower thermal resistance, and certified compliance to DO-160F Level 5 - making it the only option for mission-critical airborne systems requiring multi-stroke survivability.

FAQ
What is the clamping voltage of MPLAD18KP130CA at its rated peak pulse current?
The MPLAD18KP130CA has a maximum clamping voltage (VC) of 209 V at 100 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is measured per Figure 3 in RF01215 Rev B and defines the upper voltage limit imposed on protected circuitry during worst-case surge events, ensuring downstream components remain within safe operating voltage margins.
Does MPLAD18KP130CA require special PCB layout considerations for thermal performance?
Yes - the MPLAD18KP130CA's metal baseplate serves as both cathode and primary thermal path, so it must be soldered to a minimum 10 cm² copper pour with ≥6 thermal vias (0.3 mm diameter, filled) to achieve the specified 0.7 °C/W junction-to-case thermal resistance. Failure to implement this layout results in elevated junction temperatures and reduced surge endurance per Figure 6 derating curve.
Is MPLAD18KP130CA compliant with automotive qualification standards?
Yes, the MPLAD18KP130CA is tested and qualified to AEC-Q101 for discrete semiconductors, covering stress tests including HTGB, HTRB, TCT, and surge. This qualification validates its suitability for automotive powertrain and chassis applications, though system-level compliance with ISO 7637-2 or ISO 16750-2 requires additional circuit-level validation.
Can MPLAD18KP130CA be used in bidirectional AC signal lines?
Yes - the "CA" suffix denotes bidirectional construction, enabling symmetric clamping for AC-coupled or floating signal paths such as RS-485, CAN FD, or Ethernet PHY interfaces. Its 130 V VWM and 209 V VC provide adequate margin for 100 V RMS AC signals while suppressing common-mode transients without polarity-dependent installation.
What is the moisture sensitivity level (MSL) rating for MPLAD18KP130CA?
The MPLAD18KP130CA is rated MSL Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions (≤30 °C / 85% RH) without dry packing or baking prior to reflow soldering. This eliminates moisture-related popcorning risk and simplifies manufacturing logistics for high-reliability assembly lines.
