Product details
Overview
MPLAD36KP36CAE3/TR from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 36 V working standoff voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), and 58.1 V clamping voltage (VC) at 620 A peak impulse current - designed for lightning and load dump protection in aerospace avionics meeting RTCA DO-160 Section 22.
For engineers reviewing the MPLAD36KP36CAE3/TR datasheet, MPLAD36KP36CAE3/TR pinout, MPLAD36KP36CAE3/TR application, or MPLAD36KP36CAE3/TR equivalent, this device delivers verified IEC 61000-4-5 Class 5 secondary lightning protection (42 Ω source), RTCA/DO-160G Waveform 4 Level 4 pin injection immunity, and AEC-Q101 qualification - critical for high-reliability board-level surge suppression where thermal resistance (RθJC = 1.0 °C/W) and low-profile mounting are design constraints.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling robust protection against bipolar transients without polarity-sensitive placement. Its PLAD package features a metal base acting as the cathode for unidirectional variants and as the common terminal for bidirectional operation, with junction-to-case thermal resistance of 1.0 °C/W supporting high-energy dissipation into heatsink-mounted PCB layouts.
It meets multi-stroke lightning requirements per RTCA DO-160 Section 22 via validated 36 kW surge capability at 10/1000 μs, and supports IEC 61000-4-5 testing at multiple source impedances (2 Ω, 12 Ω, 42 Ω), with Class 5 compliance confirmed for 42 Ω up to 300 V variants - MPLAD36KP36CAE3/TR falls within the 36 V VWM range qualified for full Class 1–5 coverage at 42 Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse standoff voltage; must exceed circuit's peak operating voltage to avoid leakage conduction during normal operation. |
| VBR @ IBR | 40.0–44.2 V at 5 mA - Breakdown threshold range; defines onset of avalanche conduction during overvoltage events. |
| VC @ IPP | 58.1 V at 620 A - Clamping voltage under 10/1000 μs surge; determines maximum voltage seen by protected ICs during worst-case transient. |
| IPP | 620 A - Peak impulse current rating; defines maximum single-event surge energy the device can safely divert without failure. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables direct thermal coupling to heatsink or copper pour for sustained multi-pulse operation. |
| Package | PLAD - Surface-mount, low-profile thermoset epoxy package with metal base; optimized for minimal thermal resistance and high-power dissipation. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per stress test conditions. |
Pinout & Package
The PLAD package is a 2-terminal surface-mount device with no internal leads; terminals are formed by the metal base (cathode/anode common for bidirectional configuration) and top metallization (anode/cathode common). Polarity is marked on body; for bidirectional parts like MPLAD36KP36CAE3/TR, both terminals are functionally symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Metal Base) | Common Surge Path Terminal | Acts as shared connection point for bidirectional clamping; requires direct thermal pad connection to PCB copper for heat extraction. |
| Terminal 2 (Top Metallization) | Common Surge Path Terminal | Symmetrical to Terminal 1; completes low-inductance path for transient current flow in either polarity direction. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection against positive and negative transients without polarity-aware layout or external diodes. |
| 36 kW peak pulse power | Supports multi-stroke lightning events per RTCA DO-160 Section 22 without degradation, verified by 100% surge testing. |
| RθJC = 1.0 °C/W | Allows >500 W steady-state power dissipation at TC = 100 °C when mounted on heatsink, extending usable life under repetitive surges. |
| AEC-Q101 qualification | Confirms reliability for automotive powertrain and chassis modules subject to harsh thermal and mechanical stress environments. |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life restrictions per IPC/JEDEC J-STD-020D.1, 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 peak power (vs. 36,000 W); DO-214AA package; RθJC ≈ 40 °C/W. | Limited to single-stroke, low-energy transients; unsuitable for RTCA DO-160 multi-stroke or automotive load dump. | Select SMBJ36CA only for cost-sensitive consumer electronics with sub-100 A surge exposure. |
| SMCJ36CA | 1500 W peak power; DO-214AB package; RθJC ≈ 15 °C/W; no AEC-Q101 or DO-160 qualification data published. | Acceptable for industrial IEC 61000-4-5 Class 3–4 but lacks flight-certified validation and thermal performance for sustained surge duty. | Choose SMCJ36CA for non-aerospace, non-automotive applications requiring higher energy than SMBJ but lower cost than PLAD. |
Compared with SMBJ36CA and SMCJ36CA, MPLAD36KP36CAE3/TR delivers 24× and 24× higher peak power respectively, certified AEC-Q101 reliability, and 15× lower thermal resistance - making it the sole option for aerospace DO-160 Section 22 compliance and automotive load dump with thermal management requirements.

FAQ
What is the clamping voltage of MPLAD36KP36CAE3/TR at its rated peak pulse current?
The clamping voltage (VC) of MPLAD36KP36CAE3/TR is 58.1 V at 620 A peak impulse current (IPP) under the standard 10/1000 μs waveform. This value is measured across the device terminals during surge conduction and defines the maximum voltage imposed on protected circuitry. The low VC/VBR ratio ensures effective protection margin for 36 V nominal systems without overstressing downstream components.
Is MPLAD36KP36CAE3/TR suitable for RTCA DO-160G Section 22 lightning testing?
Yes, MPLAD36KP36CAE3/TR is explicitly validated for RTCA DO-160G Section 22 multi-stroke lightning testing. Its 36,000 W peak pulse power rating at 10/1000 μs, sub-5 ns response time, and bidirectional symmetry enable compliance with Waveform 3 (lightning-induced) and Waveform 4 (pin injection) up to Level 4. The device's thermal design (RθJC = 1.0 °C/W) supports repeated stroke endurance when properly heatsinked.
Does MPLAD36KP36CAE3/TR require moisture barrier bag storage?
No, MPLAD36KP36CAE3/TR has IPC/JEDEC J-STD-020D.1 moisture sensitivity level 1, meaning it does not absorb sufficient moisture during ambient handling to cause popcorning during reflow. Dry pack packaging and floor-life tracking are unnecessary, simplifying SMT line logistics and reducing assembly overhead compared to MS levels 2–3 devices.
How does the PLAD package of MPLAD36KP36CAE3/TR improve thermal performance over standard SMC packages?
The PLAD package of MPLAD36KP36CAE3/TR achieves a junction-to-case thermal resistance (RθJC) of 1.0 °C/W - 15× lower than typical SMC packages (~15 °C/W). This is accomplished via a void-free transfer-molded epoxy body and direct metal base contact, enabling efficient heat transfer to PCB copper pours or heatsinks. As a result, MPLAD36KP36CAE3/TR sustains >500 W steady-state power at 100 °C case temperature, unlike SMC alternatives limited to ~5 W.
Can MPLAD36KP36CAE3/TR replace unidirectional TVS diodes in existing designs?
MPLAD36KP36CAE3/TR is bidirectional and cannot directly replace unidirectional TVS diodes without verifying circuit polarity tolerance. Its symmetrical VBR and VC characteristics protect against both positive and negative transients, but if the protected circuit relies on DC bias polarity for functionality (e.g., certain CAN or RS-485 receivers), system-level validation is required. Always confirm that reverse leakage at VWM remains within acceptable limits for the host design.
