Product details
Overview
MPLAD7.5KP36CA/TR from Microchip Technology is a bidirectional 7.5 kW transient voltage suppressor (TVS) in a low-profile surface-mount PLAD package, designed for high-energy surge clamping in aerospace and automotive power rails. It features a 36 V working stand-off voltage (VWM), 40.0–44.2 V minimum breakdown voltage (V(BR)), 58.1 V maximum clamping voltage (VC) at 129 A peak pulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MPLAD7.5KP36CA/TR datasheet, MPLAD7.5KP36CA/TR pinout, MPLAD7.5KP36CA/TR application, or MPLAD7.5KP36CA/TR equivalent, this device is selected for secondary lightning protection, automotive load dump suppression, and ESD/EFT hardening where thermal management, bidirectional clamping, and AEC-Q101 qualification are critical.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling robust protection against voltage transients regardless of polarity-ideal for AC-coupled or floating signal/power lines. Its all-metal bottom provides 1.5 °C/W junction-to-case thermal resistance, minimizing junction temperature rise during repetitive 10/1000 μs surges up to 7.5 kW.
The device delivers sub-5 ns response time from 0 V to V(BR) min and maintains stable clamping performance under IEC 61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances) and RTCA/DO-160G Waveform 4 & 5A testing-validated for Level 1–5 pin injection per Waveform 4 and Level 1–3 per Waveform 5A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse standoff voltage before conduction begins; sets operating margin above nominal rail voltage. |
| V(BR) Min/Max | 40.0–44.2 V at 5 mA - Confirmed avalanche onset range; ensures predictable turn-on with <±5% tolerance at test current. |
| VC @ IPP | 58.1 V at 129 A (10/1000 μs) - Clamped voltage seen by protected circuit during worst-case surge; limits downstream stress. |
| PPP | 7,500 W - Peak pulse power handling capability; enables single-device protection against high-energy transients like load dump. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; allows efficient heat transfer to PCB copper or heatsink for sustained reliability. |
| ID @ VWM | 10 μA - Low leakage at rated standoff; minimizes quiescent power loss and avoids false triggering in high-impedance circuits. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per JEDEC standard. |
Pinout & Package
The MPLAD7.5KP36CA/TR uses a 2-terminal PLAD (Power Low-Profile Axial Device) surface-mount package with an all-metal bottom acting as the cathode heat sink. Dimensions: 8.56–8.97 mm (L) × 2.97–3.38 mm (W) × 0.56–0.96 mm (H). Mounting requires the recommended pad layout (8.97 mm × 2.97 mm) for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (positive polarity) | Conducts surge current into device during positive transients; connects to protected line. |
| Cathode | Transient current exit point & thermal path | Functions as primary heat sink; must be soldered to large copper area for RθJC = 1.5 °C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables symmetrical protection on AC or floating DC lines without polarity constraints-no external diode pairing required. |
| 7.5 kW 10/1000 μs rating | Supports single-device compliance with automotive load dump (ISO 7637-2 Pulse 5a/b) and DO-160 Section 22 multi-stroke lightning. |
| All-metal bottom thermal path | Reduces junction temperature rise by >40% vs. standard SMD packages-critical for repeated surge events in avionics. |
| AEC-Q101 qualified | Validated for automotive under-hood environments including -55°C to +150°C operation, temperature cycling, and humidity exposure. |
| RoHS & halogen-free | Complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1-no dry pack or bake required prior to reflow. |

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 | Lower PPP (600 W), larger SMB package, higher RθJA (65 °C/W), no AEC-Q101 qualification. | Suitable for consumer-grade or non-automotive industrial use; insufficient for DO-160G Level 5 or repeated load dump. | Select only when surge energy is ≤600 W and automotive/avionics qualification is not required. |
| SMCJ36CA | Higher PPP (1500 W), SMC package, RθJC ≈ 2.5 °C/W, AEC-Q101 qualified but lower energy rating than MPLAD7.5KP36CA/TR. | Meets ISO 7637-2 Pulse 5a but not full DO-160G Section 22 multi-stroke; limited to single-event automotive use. | Choose when cost is constrained and 1.5 kW peak power suffices-avoid for aerospace or high-reliability multi-stroke scenarios. |
Compared with SMBJ36CA and SMCJ36CA, the MPLAD7.5KP36CA/TR delivers 5× higher pulse power, superior thermal dissipation (1.5 °C/W), and full DO-160G/ISO 7637-2 compliance-making it the only option for certified aerospace and heavy-duty automotive systems requiring repeatable 7.5 kW surge handling.

FAQ
What is the clamping voltage of MPLAD7.5KP36CA/TR at its rated peak pulse current?
The MPLAD7.5KP36CA/TR has a maximum clamping voltage (VC) of 58.1 V at 129 A peak pulse current (IPP) under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures protected circuitry remains below critical voltage thresholds during surge events.
Is MPLAD7.5KP36CA/TR qualified for automotive applications?
Yes, MPLAD7.5KP36CA/TR is fully AEC-Q101 qualified, having undergone rigorous stress testing including temperature cycling, high-temperature reverse bias (HTRB), and surge endurance. It is approved for under-hood and powertrain applications in vehicles meeting ISO 7637-2 Pulse 5a/b requirements.
Does MPLAD7.5KP36CA/TR meet RTCA DO-160G lightning protection standards?
Yes, MPLAD7.5KP36CA/TR is validated for RTCA DO-160G Section 22 multi-stroke lightning testing and supports Level 1–5 pin injection per Waveform 4 (6.4/69 μs) and Level 1–3 per Waveform 5A (40/120 μs), making it suitable for commercial aircraft power and signal line protection.
What is the thermal resistance specification for MPLAD7.5KP36CA/TR?
The MPLAD7.5KP36CA/TR has a junction-to-case thermal resistance (RθJC) of 1.5 °C/W when mounted per the recommended pad layout. This low value is enabled by its all-metal bottom cathode structure, allowing efficient heat transfer to the PCB substrate and sustaining repeated 7.5 kW surges.
How does the bidirectional design of MPLAD7.5KP36CA/TR affect its circuit implementation?
The bidirectional configuration of MPLAD7.5KP36CA/TR eliminates polarity concerns during placement-it clamps equally for positive and negative transients. This simplifies layout on AC-coupled lines, differential buses, or floating DC rails, and removes the need for dual unidirectional devices or external polarity management circuitry.
