Product details
Overview
MPLAD36KP16AE3/TR from Microsemi (now Microchip) is a unidirectional surface-mount transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 16 V working standoff voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), and 27.2 V clamping voltage (VC) at 450 A peak impulse current - designed for lightning and load dump protection in aerospace and automotive power rails.
For engineers reviewing the MPLAD36KP16AE3/TR datasheet, MPLAD36KP16AE3/TR pinout, MPLAD36KP16AE3/TR application, or MPLAD36KP16AE3/TR equivalent, key selection criteria include its 1.0 °C/W junction-to-case thermal resistance, <100 ps clamping response time, AEC-Q101 qualification, RoHS-compliant matte-tin plating, and PLAD package compatibility with high-current PCB layouts per Figure 7 pad layout.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp fast transients, with bidirectional variants designated by "CA" suffix (not applicable here). Its low RθJC of 1.0 °C/W enables direct thermal coupling to heatsinked copper pads, supporting multi-stroke DO-160 Section 22 compliance when mounted on 1 oz FR4 with recommended pad geometry.
It delivers 27.2 V clamping at 450 A (10/1000 μs), with standby leakage ≤150 µA at 16 V, and temperature coefficient of breakdown voltage ≤12 mV/°C - enabling stable overvoltage protection across –55 °C to +150 °C junction temperature range without derating below 100 °C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous DC or repetitive peak reverse voltage before conduction begins; sets minimum system operating margin. |
| VBR | 17.8–19.7 V at 5 mA - precise avalanche onset range ensures predictable turn-on during surge events. |
| VC | 27.2 V at IPP = 450 A - clamped voltage seen by protected circuit under worst-case 10/1000 μs surge. |
| IPP | 450 A - peak non-repetitive surge current capability defining single-event energy handling (36 kW). |
| RθJC | 1.0 °C/W - enables efficient heat transfer to PCB copper, critical for sustaining multi-pulse DO-160 testing. |
| TJ | –55 to +150 °C - full operational junction temperature range validated per AEC-Q101 stress tests. |
| αV(BR) | ≤12 mV/°C - low temperature drift preserves clamping accuracy across wide ambient conditions. |
Pinout & Package
The MPLAD36KP16AE3/TR uses the PLAD (Power Leadless Array Device) package: a low-profile, thermally optimized surface-mount outline with metal base acting as cathode terminal and primary heat path. Dimensions per Figure 6: 10.3 × 8.3 × 3.2 mm (L × W × H), weight ≈1.8 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (top metallization) | Transient current entry point | Connects to protected line (e.g., 12 V rail); current flows anode-to-cathode during clamping. |
| Cathode (metal base) | Common return and thermal interface | Soldered directly to large copper pour or heatsink; serves as both electrical return and primary thermal conduction path. |
Key Features
| Feature | Design Value |
|---|---|
| 36 kW peak pulse rating | Enables single-device protection against severe lightning-induced surges per RTCA DO-160G Waveform 4 (Level 4/5) and IEC 61000-4-5 Class 5. |
| AEC-Q101 qualification | Validates reliability for automotive powertrain and chassis applications including 12 V/24 V battery systems subject to load dump. |
| 1.0 °C/W RθJC | Allows >90% of surge energy to dissipate into PCB copper, reducing thermal stress and enabling compact board-level protection. |
| RoHS-compliant e3 marking | Confirms matte-tin plating meets JEDEC J-STD-020D.1 Level 1 moisture sensitivity - no dry pack required prior to reflow. |
| <100 ps response time | Clamps transients before sensitive downstream ICs (e.g., CAN transceivers, microcontrollers) experience damaging overvoltage. |
Applications
| Aerospace Power Distribution | Automotive Battery Rail Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Lower 600 W rating (vs. 36,000 W), SMB package, RθJC = 15 °C/W | Single-stroke ESD/EFT only; unsuitable for DO-160 multi-stroke or load dump | Select only for cost-sensitive consumer electronics with sub-100 A surge requirements. |
| SMCJ16A | 3,000 W rating (1/12th of MPLAD36KP16AE3/TR), SMC package, RθJC = 3.5 °C/W | Limited to IEC 61000-4-5 Class 3 (42 Ω source); fails Class 4/5 and DO-160G Level 4 | Use where space constraints prohibit PLAD footprint but higher power than SMBJ is needed. |
Compared with SMBJ16A and SMCJ16A, MPLAD36KP16AE3/TR provides 12× and 12× higher peak power handling respectively, 15× and 3.5× lower thermal resistance, and certified compliance with aerospace-grade multi-stroke standards - making it the only viable option for mission-critical 16 V rail protection requiring sustained surge endurance.

FAQ
What is the clamping voltage of MPLAD36KP16AE3/TR at its rated peak pulse current?
The MPLAD36KP16AE3/TR has a maximum clamping voltage (VC) of 27.2 V when subjected to its rated peak pulse current of 450 A under the standard 10/1000 μs waveform. This value is measured per test condition defined in Table 4 of the official datasheet and represents the upper voltage limit imposed on the protected circuit during worst-case surge events.
Is MPLAD36KP16AE3/TR suitable for automotive load dump protection per ISO 7637-2?
Yes, MPLAD36KP16AE3/TR is qualified for automotive load dump protection per ISO 7637-2 Pulse 5a/b. Its 36,000 W rating, 450 A peak current capability, and AEC-Q101 qualification confirm suitability for 12 V systems. The 16 V VWM aligns with nominal battery voltage, and its 27.2 V clamping ensures downstream 33 V-rated components remain within safe operating limits.
Does MPLAD36KP16AE3/TR require dry pack handling per J-STD-020?
No, MPLAD36KP16AE3/TR has IPC/JEDEC J-STD-020D.1 moisture sensitivity level (MSL) 1, meaning it may be stored and processed indefinitely at ambient conditions without dry packing. This eliminates baking requirements prior to reflow soldering and simplifies manufacturing logistics for high-volume assembly.
What is the thermal resistance from junction to case (RθJC) for MPLAD36KP16AE3/TR?
The junction-to-case thermal resistance (RθJC) of MPLAD36KP16AE3/TR is 1.0 °C/W, as specified in Table 3 of the datasheet. This low value reflects the PLAD package's metal-base construction, enabling efficient heat transfer from the silicon die directly into the PCB copper or external heatsink - a critical parameter for multi-pulse surge endurance.
Can MPLAD36KP16AE3/TR be used in bidirectional configurations?
No, MPLAD36KP16AE3/TR is a unidirectional TVS, indicated by the "A" suffix (not "CA"). It conducts only during positive overvoltage events relative to ground. For bidirectional protection - such as AC line or data line applications - a variant like MPLAD36KP16CA must be selected instead, as confirmed by the nomenclature table and electrical characteristics section.
