Product details
Overview
MPLAD36KP150AE3/TR from Microsemi is a unidirectional 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 thermal resistance (RθJC = 1.0 °C/W) and fast clamping (<100 ps response) for lightning and load dump protection in aerospace and automotive power systems.
For engineers reviewing the MPLAD36KP150AE3/TR datasheet, MPLAD36KP150AE3/TR pinout, MPLAD36KP150AE3/TR application, or MPLAD36KP150AE3/TR equivalent, this device is selected for high-energy transient suppression where DO-160 Section 22 compliance, IEC 61000-4-5 Class 5 capability (42 Ω source), and AEC-Q101 qualification are required - especially in DC bus lines of avionics power converters and vehicle ECUs.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp overvoltage transients before downstream circuitry sustains damage. Its PLAD package features a metal base acting as the cathode terminal, enabling direct thermal coupling to PCB copper pour or heatsink for efficient junction-to-case heat dissipation.
It is characterized for operation across –55 °C to +150 °C junction temperature, with derated steady-state power (PD = 504 W at TC = 100 °C) and strict 10 µA maximum standby current (ID) at VWM, ensuring minimal leakage in high-impedance monitoring paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V - Maximum continuous DC or repetitive peak reverse voltage applied without conduction; sets minimum system operating margin. |
| VBR @ IBR | 167–185 V @ 5 mA - Breakdown onset range; defines turn-on threshold under standardized test current. |
| VC @ IPP | 243 V @ 243 A - Clamped voltage during full-rated 10/1000 μs surge; determines maximum stress on protected ICs. |
| IPP | 243 A - Peak non-repetitive impulse current it withstands without degradation; correlates directly to 36 kW rating. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables precise thermal design when mounted on heatsink or thick copper. |
| ID @ VWM | 10 µA max - Standby leakage at rated standoff; critical for low-power sensor or reference circuits. |
| tCLAMP | <100 ps - Time from 0 V to VBR min; ensures sub-nanosecond response to fast-rising ESD or switching spikes. |
Pinout & Package
The MPLAD36KP150AE3/TR uses the PLAD surface-mount package: a low-profile, void-free thermosetting epoxy body (UL94V-0) with a metal base serving as the cathode terminal. The anode is the top-side metallized pad. Total weight is ~1.7–2.0 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Cathode | Primary current return path and thermal interface; must be soldered to large copper area or heatsink for RθJC = 1.0 °C/W performance. |
| Top Metallized Pad | Anode | Transient current entry point; connects to line being protected (e.g., 12–48 V DC bus). |
Key Features

|---|---|
Use Scenario: Protecting 28 V DC distribution buses in commercial aircraft against multi-stroke lightning transients per RTCA DO-160G Section 22. IC Role / Device Role / Timing Role: Unidirectional TVS placed between bus rail and chassis ground to clamp induced surges before they reach power modules and FPGAs. Use Value: With 243 V clamping at 243 A, limits voltage stress on downstream 32 V-rated DC-DC controllers while meeting Class 5 waveform 4 (6.4/69 μs) requirements. | Use Scenario: Safeguarding 12 V battery-fed engine control units from load dump events (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Primary transient suppressor on main power input, positioned upstream of PMICs and microcontrollers. Use Value: 36 kW rating absorbs 120 V/350 ms load dump energy without failure; AEC-Q101 qualification ensures reliability across –40 °C to +125 °C ambient. |
| Industrial Motor Drive DC Link | Railway Signaling Power Supply |
Use Scenario: Clamping voltage spikes on 400 V DC link rails caused by IGBT switching in variable-frequency drives. IC Role / Device Role / Timing Role: Parallel-connected TVS across DC bus to limit dv/dt and prevent gate driver latch-up or capacitor overvoltage. Use Value: 1.0 °C/W RθJC allows direct mounting to aluminum heatsink, sustaining repeated 10/1000 μs surges without thermal runaway. | Use Scenario: Secondary surge protection for 72 V DC signaling power supplies in EN 50121-3-2 compliant railway infrastructure. IC Role / Device Role / Timing Role: Final-stage TVS on output side of isolated DC-DC converter, guarding against coupled transients from track-side EMI. Use Value: Meets IEC 61000-4-5 Class 4 (12 Ω source) with 243 V clamping, reducing risk of false tripping in safety-critical relay logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Lower 600 W rating (vs. 36,000 W); SMB package; RθJC ≈ 45 °C/W. | Not suitable for DO-160G Section 22 or ISO 7637-2 Pulse 5a; limited to low-energy ESD/EFT. | Select only for cost-sensitive, low-risk consumer electronics with <50 A surge exposure. |
| SMCJ150A | 3,000 W rating (1/12× power); SMC package; same VWM/VBR tolerance but higher clamping (246 V). | Supports IEC 61000-4-5 Class 3 (42 Ω), not Class 5; insufficient for multi-stroke lightning testing. | Use where space constraints prohibit PLAD footprint but higher energy than SMBJ is needed. |
Compared with SMBJ150A and SMCJ150A, the MPLAD36KP150AE3/TR delivers 12× and 12× higher peak power handling respectively, enabling robust protection in mission-critical aerospace and heavy-duty automotive systems where single-event survivability and thermal stability under repeated surges are mandatory.

FAQ
What is the clamping voltage of MPLAD36KP150AE3/TR at its rated peak pulse current?
The MPLAD36KP150AE3/TR has a maximum clamping voltage (VC) of 243 V when subjected to its rated peak pulse current (IPP) of 243 A under the standard 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees the protected circuit sees no more than 243 V during full-rated surge events - critical for ensuring compatibility with 28 V or 48 V system voltage tolerances.
Is MPLAD36KP150AE3/TR suitable for automotive under-hood applications?
Yes, MPLAD36KP150AE3/TR is AEC-Q101 qualified and rated for junction temperatures from –55 °C to +150 °C, making it suitable for under-hood automotive applications such as engine control units and battery management systems. Its 36 kW surge rating meets ISO 7637-2 Pulse 5a load dump requirements, and its RoHS-compliant (e3) matte-tin plating supports lead-free reflow profiles used in modern automotive manufacturing.
How does the PLAD package of MPLAD36KP150AE3/TR improve thermal performance compared to SMB or SMC packages?
The PLAD package of MPLAD36KP150AE3/TR achieves a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W - over 40× lower than typical SMB packages (~45 °C/W) and ~10× lower than SMC packages (~10 °C/W). This is enabled by its metal base cathode, which provides direct thermal conduction to PCB copper or external heatsinks, allowing sustained high-energy surge handling without thermal runaway.
Does MPLAD36KP150AE3/TR meet RTCA DO-160G Section 22 lightning requirements?
Yes, MPLAD36KP150AE3/TR is explicitly designed and validated for RTCA DO-160G Section 22 multi-stroke lightning testing. Its 36,000 W rating, sub-100 ps response time, and 243 V clamping at 243 A enable compliance with Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) at Level 4 and Level 5 severity - confirmed in Microsemi's application documentation and test reports.
What is the polarity configuration and marking convention for MPLAD36KP150AE3/TR?
MPLAD36KP150AE3/TR is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). Its cathode is the metal base (bottom surface), and the anode is the top metallized pad. The device body is marked with the full part number "MPLAD36KP150AE3", and polarity is confirmed by the cathode-down mounting orientation required for proper circuit protection function.
