The **M5R85TL-R** is a specific high-performance, high-voltage Power MOSFET typically used in power management and switching applications. Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. Technical Specifications The "M5R85TL-R" belongs to a class of Super Junction MOSFETs, designed to minimize on-resistance while maintaining high breakdown voltages. | Parameter | Typical Value | Description | | :--- | :--- | :--- | | **Drain-Source Voltage ($V_{DSS}$)** | 850V | The maximum voltage the device can withstand. | | **Continuous Drain Current ($I_D$)** | ~5A - 8A | Varies slightly by temperature; max current flow. | | **Static Drain-Source On-Resistance ($R_{DS(on)}$)** | < 1.0 $\Omega$ | Low resistance to minimize heat loss during operation. | | **Gate-Source Voltage ($V_{GS}$)** | $\pm$30V | The control voltage range for the gate. | | **Package Type** | TO-220 / TO-220F | Common through-hole packages for heat dissipation. | --- ## 2. Key Internal Features * **Super Junction Technology:** Unlike standard MOSFETs, this part uses a vertical charge balance structure. This allows for a significantly lower $R_{DS(on)}$ per unit area, reducing conduction losses. * **Low Gate Charge ($Q_g$):** This allows for faster switching speeds, which is critical for high-frequency power supplies. * **High Avalanche Ruggedness:** The internal structure is designed to handle "avalanche" events (voltage spikes) without immediate failure. * **Internal Diode:** It includes a fast-recovery body diode, which is useful in inductive load switching. --- ## 3. Typical Applications Because of its high voltage rating (850V) and efficient switching, it is commonly found in: 1. **Switch Mode Power Supplies (SMPS):** Used as the primary switch in AC-DC converters. 2. **LED Lighting Drivers:** Provides stable power regulation for high-power LED arrays. 3. **Adapter/Chargers:** Used in laptop bricks and industrial power adapters. 4. **PFC (Power Factor Correction):** Used to improve the efficiency of power grids in consumer electronics. --- ## 4. Pin Configuration For the standard TO-220 package, the pinout is typically: | Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | **Gate** | Controls the "On/Off" state of the MOSFET. | | 2 | **Drain** | Connected to the load (High Voltage side). | | 3 | **Source** | Connected to the ground or return path. | ---
