Product details
Overview
MPLAD36KP160CA/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 160 V working standoff voltage (VWM) and 259 V maximum clamping voltage (VC) at 139 A peak impulse current (IPP). It is designed for secondary lightning protection in aerospace avionics per RTCA DO-160G Section 22 Waveform 4 and IEC 61000-4-5, and meets AEC-Q101 qualification.
For engineers reviewing the MPLAD36KP160CA/TR datasheet, MPLAD36KP160CA/TR pinout, MPLAD36KP160CA/TR application, or MPLAD36KP160CA/TR equivalent, key selection criteria include bidirectional polarity, 1.0 °C/W junction-to-case thermal resistance, <5 ns clamping response time, RoHS-compliant matte-tin plating, and compatibility with FR4 PCBs using the recommended PLAD pad layout.
Technical Context
This device operates as a silicon avalanche diode-based TVS, leveraging low-differential-resistance clamping during transients to limit voltage across protected circuitry. Its bidirectional construction enables symmetrical suppression of both positive and negative polarity surges without external polarity conditioning.
Thermal design is critical: RθJC = 1.0 °C/W enables effective heat transfer to an external heatsink, while RθJA = 50 °C/W (on 1 oz Cu FR4) defines ambient-limited dissipation. The metal base serves as the cathode terminal and primary thermal path - no internal die attach voids per UL94V-0 void-free epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous DC or repetitive peak reverse voltage applied without conduction; sets minimum system operating voltage margin. |
| VBR min/max | 178–197 V at 5 mA - Confirmed breakdown threshold range; ensures reliable turn-on before damaging overvoltage occurs. |
| VC @ IPP | 259 V at 139 A - Clamped voltage during full-rated 10/1000 μs surge; defines worst-case voltage seen by downstream ICs. |
| IPP | 139 A - Peak non-repetitive surge current capability; determines survivability under IEC 61000-4-5 Class 4 (12 Ω source) events. |
| TJ range | –55 to +150 °C - Full operational junction temperature span; supports extended automotive and avionics environments. |
| RθJC | 1.0 °C/W - Low thermal resistance from junction to case; mandates direct metal-base mounting to heatsink for sustained surge handling. |
| αV(BR) | 195 mV/°C - Temperature coefficient of breakdown voltage; used to calculate VBR derating at elevated temperatures. |
Pinout & Package
The MPLAD36KP160CA/TR uses the PLAD (Power Leadless Array Device) package: a low-profile, thermally optimized surface-mount outline with a metal base acting as the cathode terminal and primary thermal interface. Dimensions are 10.3 × 8.2 × 3.5 mm (L × W × H), weight ≈ 1.8 g, UL94V-0 void-free epoxy body, matte-tin plated terminals.
| 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 performance. |
| Top Surface Pad | Anode (Bidirectional) | Exposed metallization on top surface; forms second terminal; polarity is symmetric - no directional orientation required. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional 36 kW surge rating | Enables single-device protection of AC-coupled or floating signal/power lines without polarity awareness or external diodes. |
| Clamping response <5 ns | Ensures sub-microsecond voltage limiting during fast transients like ESD and RTCA DO-160G Waveform 4 (6.4/69 μs). |
| AEC-Q101 qualified | Validates reliability for automotive powertrain and chassis applications including 12 V/24 V battery systems subject to load dump. |
| Moisture Sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints - can be mounted directly after opening standard packaging. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | 600 W rating (vs. 36,000 W); SMB package; RθJC ≈ 25 °C/W; VC = 259 V @ 2.2 A. | Only suitable for low-energy ESD/EFT; cannot meet DO-160G Section 22 or IEC 61000-4-5 Class 4/5. | Select only for board-level ESD protection where surge energy is below 10 J. |
| SMCJ160CA | 1500 W rating; SMC package; RθJC ≈ 10 °C/W; VC = 259 V @ 13.7 A. | Meets IEC 61000-4-5 Class 3 (42 Ω), but fails Class 4/5 and DO-160G Waveform 4/5A testing. | Use when cost sensitivity outweighs aerospace/automotive certification requirements and surge energy is ≤ 30 J. |
Compared with SMBJ160CA and SMCJ160CA, the MPLAD36KP160CA/TR delivers 60× and 24× higher peak pulse power respectively, enabling compliance with stringent aviation and heavy-duty automotive surge standards - not achievable with smaller SMD packages due to thermal and current-handling limitations.

FAQ
What is the clamping voltage of MPLAD36KP160CA/TR at its rated peak pulse current?
The MPLAD36KP160CA/TR has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak impulse current (IPP) of 139 A under the 10/1000 μs waveform. This value is measured across the device terminals during surge conduction and defines the upper voltage limit imposed on protected circuitry - critical for ensuring downstream components remain within their absolute maximum ratings.
Is MPLAD36KP160CA/TR suitable for automotive applications?
Yes, the MPLAD36KP160CA/TR is AEC-Q101 qualified and explicitly rated for automotive load dump protection per ISO 7637-2. Its 160 V working standoff voltage accommodates 12 V and 24 V battery systems during cold-crank and transient overvoltage events, and its bidirectional architecture eliminates polarity concerns in floating or AC-coupled subsystems commonly found in modern ECUs and ADAS modules.
How does the PLAD package of MPLAD36KP160CA/TR improve thermal performance compared to standard SMC or SMB packages?
The PLAD package of MPLAD36KP160CA/TR achieves a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W - over 10× lower than SMC (≈10 °C/W) and 25× lower than SMB (≈25 °C/W). This is enabled by its exposed metal base, which provides a direct, low-impedance thermal path to an external heatsink or large PCB copper area, allowing sustained dissipation of high-energy surges without thermal runaway.
Does MPLAD36KP160CA/TR require special PCB layout considerations?
Yes - the MPLAD36KP160CA/TR requires adherence to the manufacturer's specified pad layout (Figure 7 in datasheet), including minimum 10.3 × 8.2 mm thermal pad with multiple vias to inner-layer ground planes. The metal base must be fully soldered to this pad; insufficient solder coverage or undersized copper increases RθJA and risks premature failure during repeated surges.
What standards does MPLAD36KP160CA/TR comply with for lightning surge immunity?
The MPLAD36KP160CA/TR is validated for RTCA DO-160G Section 22 Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) up to Level 4 and Level 5 respectively, and meets IEC 61000-4-5 for secondary lightning protection across Classes 1–5 depending on source impedance (2 Ω, 12 Ω, or 42 Ω). Its 36 kW rating and <5 ns response make it suitable for aircraft power and data line hardening.
