Product details
Overview
MPLAD36KP150CAE3/TR from Microchip (formerly Microsemi) is a bidirectional surface-mount transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 150 V working standoff voltage (VWM), 167–185 V breakdown voltage (VBR), and 243 A peak pulse current (IPP). It delivers low-clamping performance (VC ≤ 243 V) for secondary lightning protection in avionics power inputs compliant with RTCA DO-160 Section 22.
For engineers reviewing the MPLAD36KP150CAE3/TR datasheet, MPLAD36KP150CAE3/TR pinout, MPLAD36KP150CAE3/TR application, or MPLAD36KP150CAE3/TR equivalent, this device is selected for high-energy surge suppression where bidirectional polarity, thermal robustness (RθJC = 1.0 °C/W), and IEC 61000-4-5 Class 4/5 compliance with 42 Ω source impedance are required.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transients above its VWM, with sub-5 ns response time in bidirectional configuration and clamping voltage defined at IPP = 243 A per 10/1000 μs waveform. Its metal-base PLAD package enables direct thermal coupling to heatsinks, supporting continuous power dissipation up to 504 W at TC = 100 °C.
The device meets AEC-Q101 qualification and is moisture-sensitivity Level 1 (no dry pack required), with RoHS-compliant matte-tin plating and traceable wafer/assembly lot control. It is specifically validated for pin-injection protection per RTCA/DO-160G Waveform 4 (Level 4/5) and Waveform 5A (Level 4 up to 78 V, Level 5 up to 38 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V DC - Maximum continuous operating voltage before conduction begins; sets minimum system bus rating for reliable standby isolation. |
| VBR @ IBR | 167–185 V @ 5 mA - Breakdown threshold range; ensures consistent turn-on across temperature and process variation. |
| VC @ IPP | ≤243 V @ 243 A - Clamped voltage during full-rated surge; defines maximum stress imposed on downstream circuitry. |
| IPP | 243 A - Peak non-repetitive surge current capability at 10/1000 μs; determines survivability against multi-stroke lightning events. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables high-power derating when mounted on thermally optimized heatsinks. |
| TJ/TSTG | –55 to +150 °C - Operating and storage temperature range; supports deployment in extended-temperature avionics and industrial environments. |
| αV(BR) | 183 mV/°C - Temperature coefficient of breakdown voltage; allows accurate thermal drift modeling in high-ambient designs. |
Pinout & Package
The MPLAD36KP150CAE3/TR uses the PLAD surface-mount package: void-free UL94V-0 epoxy body with metal base acting as cathode terminal; total weight ≈1.7–2.0 g; dimensions per Figure 6 (datasheet p.9); recommended pad layout per Figure 7 (datasheet p.10).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Cathode (Bidirectional) | Common terminal for both polarities; must be soldered to large copper pour or heatsink for thermal and electrical integrity. |
| Top Surface Marking Area | Anode (Bidirectional) | Electrically isolated top surface; connects to protected line via PCB trace; polarity marking "CA" confirms bidirectional construction. |
Key Features

| AEC-Q101 qualified & lot traceable | Supports automotive-grade reliability requirements and full supply-chain traceability for safety-critical subsystems. |
| RθJC = 1.0 °C/W | Allows >500 W steady-state power handling at 100 °C case temperature-enables compact thermal design without forced air. |
| RTCA DO-160G Waveform 4/5A compliance | Validated for pin-injection testing up to Level 5 (Waveform 4: 150 VWM variant qualifies to 300 VWM max; Waveform 5A: qualifies to 38 VWM max). |
| Moisture Level 1 (J-STD-020D.1) | Eliminates bake-out requirement prior to reflow, reducing manufacturing cost and avoiding thermal stress on adjacent components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Lower peak power (600 W), smaller SMB package, RθJC ≈ 35 °C/W, VC = 243 V @ 22.5 A. | Not suitable for DO-160G Section 22 multi-stroke lightning; limited to low-energy ESD/EFT in consumer electronics. | Select only for space-constrained, low-risk environments where 36 kW surge capacity is unnecessary. |
| SMCJ150CA | Higher peak power (1500 W), SMC package, RθJC ≈ 15 °C/W, VC = 243 V @ 61.5 A. | Meets IEC 61000-4-5 Class 3 but not Class 4/5 with 42 Ω source; insufficient for certified avionics lightning protection. | Use where moderate surge energy (≤1.5 kW) and lower cost are prioritized over aerospace qualification. |
Compared with SMBJ150CA and SMCJ150CA, the MPLAD36KP150CAE3/TR delivers 24× and 24× higher peak pulse power respectively, enabling certified compliance with RTCA DO-160G Section 22 and IEC 61000-4-5 Class 5-making it the only option among the three for high-reliability airborne systems.

FAQ
What is the clamping voltage of MPLAD36KP150CAE3/TR at its rated peak pulse current?
The MPLAD36KP150CAE3/TR has a maximum clamping voltage (VC) of 243 V when subjected to its rated peak pulse current (IPP) of 243 A under the 10/1000 μs waveform. This value is measured per standard test conditions in the datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The low VC/VWM ratio of 1.62 ensures downstream components remain within safe operating limits.
Is MPLAD36KP150CAE3/TR qualified for automotive applications?
Yes, the MPLAD36KP150CAE3/TR is AEC-Q101 qualified, confirming its suitability for automotive electronic systems. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and humidity bias life testing. While primarily targeted at aerospace, its AEC-Q101 status supports use in under-hood powertrain and battery management applications where 150 V standoff and high-energy surge immunity are required.
Does MPLAD36KP150CAE3/TR require baking before reflow soldering?
No, the MPLAD36KP150CAE3/TR is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020D.1, meaning it may be stored indefinitely at ambient conditions and placed directly into reflow without pre-baking. This eliminates process steps, reduces thermal stress on the component and surrounding PCB, and lowers manufacturing cost-particularly valuable in high-mix, low-volume avionics assembly.
How does the PLAD package of MPLAD36KP150CAE3/TR improve thermal performance compared to SMB/SMC packages?
The PLAD package of MPLAD36KP150CAE3/TR features a metal base that serves as the cathode terminal and provides direct thermal conduction path to the PCB or heatsink, achieving RθJC = 1.0 °C/W-over 30× better than SMBJ (≈35 °C/W) and >15× better than SMCJ (≈15 °C/W). This enables sustained power dissipation up to 504 W at 100 °C case temperature, making MPLAD36KP150CAE3/TR uniquely capable of handling repeated high-energy transients without thermal runaway.
Can MPLAD36KP150CAE3/TR be used for RTCA DO-160G Section 22 lightning protection?
Yes, the MPLAD36KP150CAE3/TR is explicitly designed and validated for RTCA DO-160G Section 22 multi-stroke lightning testing. Its 36,000 W peak pulse rating, sub-5 ns response time in bidirectional mode, and documented performance across Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) confirm compliance. The datasheet states Level 4/5 qualification for Waveform 4 up to 300 VWM, fully covering the 150 V rating of MPLAD36KP150CAE3/TR.
