Product details
Overview
MPLAD36KP100CA/TR from Microsemi (now Microchip) is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power rails. It delivers 36,000 W peak pulse power at 10/1000 μs, clamps transients to ≤162 V at 223 A, and features a 100 V working standoff voltage (VWM) with ±5% tolerance. Its low thermal resistance (RθJC = 1.0 °C/W) enables robust multi-stroke lightning protection per RTCA DO-160 Section 22.
For engineers reviewing the MPLAD36KP100CA/TR datasheet, MPLAD36KP100CA/TR pinout, MPLAD36KP100CA/TR application, or MPLAD36KP100CA/TR equivalent, this device is selected for secondary lightning protection (IEC 61000-4-5), load dump suppression, and pin-injection immunity (DO-160G Waveform 4 & 5A) where bidirectional clamping, high IPP, and minimal thermal derating are critical.
Technical Context
This TVS operates in avalanche breakdown mode with a specified breakdown voltage (VBR) of 111–123 V at 5 mA test current and a maximum clamping voltage (VC) of 162 V at 223 A peak impulse current (IPP). Its bidirectional construction eliminates polarity dependency in AC-coupled or floating bus lines.
The PLAD package integrates a metal base acting as the cathode terminal for unidirectional variants and serves as the common reference plane for bidirectional operation. Thermal performance is optimized via direct metal-to-heat-sink mounting, enabling sustained power dissipation up to 504 W at 100 °C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V DC - Maximum continuous operating voltage before conduction begins; sets minimum system rail rating for safe integration. |
| VBR @ 5 mA | 111–123 V - Breakdown onset range; ensures reliable turn-on above normal operating transients but below destructive overvoltage thresholds. |
| VC @ IPP | 162 V at 223 A - Clamped voltage during full-rated 10/1000 μs surge; defines worst-case downstream voltage stress on protected ICs. |
| IPP | 223 A - Peak non-repetitive surge current capacity; supports Class 4/5 lightning immunity per IEC 61000-4-5 with 42 Ω source impedance. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; allows precise heatsink sizing for multi-pulse duty cycles without thermal runaway. |
| TJ Range | –55 to +150 °C - Full operational junction temperature range; validated for under-hood automotive and avionics environments. |
| αV(BR) | 122 mV/°C - Temperature coefficient of breakdown voltage; enables accurate VBR prediction across temperature for margin analysis. |
Pinout & Package
The MPLAD36KP100CA/TR uses the PLAD surface-mount package: a low-profile, void-free thermosetting epoxy body with a metal base acting as the common terminal. The device has two terminals - anode and cathode - symmetrically arranged for bidirectional operation; polarity is not marked externally due to CA suffix designation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (top metallization) | Positive surge path input | Accepts positive-going transients relative to common; forms one half of symmetrical clamping diode pair. |
| Cathode (metal base) | Common reference / heat sink interface | Serves as thermal conduction path to PCB copper pour or external heatsink; electrically common to both avalanche junctions in bidirectional configuration. |
Key Features
| Feature | Design Value |
|---|---|

| 36 kW peak pulse rating | Supports multi-stroke lightning events per RTCA DO-160 Section 22 without degradation, verified by lot-level surge testing. |
| AEC-Q101 qualification | Validated for automotive under-hood applications including load dump (ISO 7637-2) and ESD (IEC 61000-4-2). |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement and bake-out prior to reflow; compatible with standard SMT assembly processes per J-STD-020D.1. |
| RoHS-compliant (e3) | Meets EU Directive 2011/65/EU with matte-tin plating; no lead or hazardous substances in terminals or mold compound. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower peak power (600 W), smaller SMB package, higher RθJA (110 °C/W), VC = 165 V at 32.4 A. | Suitable only for single-event, low-duty-cycle surges; insufficient for DO-160 multi-stroke or automotive load dump. | Select SMBJ100CA only for cost-sensitive consumer electronics with limited surge exposure. |
| SMCJ100CA | Higher peak power (1500 W), larger SMC package, RθJA = 35 °C/W, VC = 165 V at 91.1 A. | Meets IEC 61000-4-5 Class 3 but fails Class 4/5; lacks AEC-Q101 and DO-160 qualification. | Choose SMCJ100CA for industrial controls requiring moderate surge immunity without aerospace/automotive certification. |
Compared with SMBJ100CA and SMCJ100CA, the MPLAD36KP100CA/TR provides 24× and 24× higher peak pulse power respectively, certified thermal performance for sustained multi-pulse operation, and formal qualification for aviation and automotive safety-critical systems - making it the sole option for DO-160G Level 5 and ISO 7637-2 Pulse 5a compliance.

FAQ
What is the clamping voltage of MPLAD36KP100CA/TR at its rated peak pulse current?
The MPLAD36KP100CA/TR has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak impulse current (IPP) of 223 A under the standard 10/1000 μs waveform. This value is measured across the device terminals during surge conduction and defines the upper voltage limit imposed on downstream circuitry during full-rated transient events. The MPLAD36KP100CA/TR maintains this clamping performance across its qualified temperature range (–55 to +150 °C).
Is MPLAD36KP100CA/TR suitable for automotive load dump protection per ISO 7637-2?
Yes, the MPLAD36KP100CA/TR is AEC-Q101 qualified and explicitly rated for automotive load dump protection. Its 36,000 W peak pulse power, 223 A IPP, and 162 V clamping voltage enable compliance with ISO 7637-2 Pulse 5a (load dump) requirements for 12 V systems. The device's low RθJC (1.0 °C/W) ensures thermal survivability during repeated load dump events, and its bidirectional construction accommodates reverse battery connection scenarios.
How does the PLAD package of MPLAD36KP100CA/TR improve thermal performance compared to standard SMC or SMB packages?
The PLAD package of MPLAD36KP100CA/TR features a metal base that serves as both the electrical terminal and primary thermal conduction path, achieving a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W - over 35× lower than typical SMC packages (~35 °C/W) and ~110× lower than SMB packages (~110 °C/W). This enables direct mounting to heatsinks or large PCB copper pours, allowing sustained power dissipation up to 504 W at 100 °C case temperature, which is essential for multi-stroke surge applications.
Does MPLAD36KP100CA/TR meet RTCA DO-160G Section 22 lightning protection requirements?
Yes, the MPLAD36KP100CA/TR is specifically designed and tested for RTCA DO-160G Section 22 lightning-induced transient protection. Its 36 kW rating, sub-5 ns response time, and bidirectional architecture support Level 4 and Level 5 immunity for Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) at 25 °C. The device's qualification includes multi-stroke endurance validation, making it suitable for primary or secondary lightning protection in avionics power distribution units.
What is the meaning of the "CA" suffix in MPLAD36KP100CA/TR?
Within the MPLAD36KP product family, the "CA" suffix in MPLAD36KP100CA/TR denotes bidirectional construction. Unlike unidirectional variants ending in "A", the CA version contains two opposing avalanche diodes integrated into a single PLAD package, enabling symmetrical clamping for both positive and negative transients. This eliminates polarity concerns in AC-coupled circuits, differential signaling paths, or floating power domains - a key requirement for telecom, aerospace, and industrial applications.
