RL207 1000V 2A Silicon Rectifier Diode DO-15

RL207 1000V 2A Silicon Rectifier Diode DO-15 is a ubiquitous and robust standard recovery rectifier, designed specifically for converting alternating current (AC) into direct current (DC) in a variety of power supply applications. This general-purpose diode offers an impressive Peak Inverse Voltage (PIV) rating of 1000V combined with a generous continuous forward current capacity of 2A. Consequently, the RL207 delivers reliable performance in medium-power circuits where durability and high voltage blocking capabilities are essential. Packaged in the industry-standard DO-15 axial lead format, you can easily integrate this rectifier into power adapters, battery chargers, and general rectification circuits, providing critical protection against reverse voltage spikes.

Key Features:

• High Reverse Voltage: Offers a non-repetitive Peak Inverse Voltage (V_RRM) of 1000 V, making it suitable for standard 120V AC and 240V AC line voltage applications with significant safety margin.
• Substantial Current Rating: Handles a maximum average rectified forward current (I_F(AV)) of 2.0 A, supporting medium-load power circuits.
• Standard Recovery Time: Provides dependable general-purpose rectification with a standard reverse recovery time (t_rr).
• Hermetically Sealed Package: The DO-15 through-hole package ensures high reliability and mechanical stability, offering effective protection against environmental factors.
• Low Forward Voltage Drop: Minimizes power loss during conduction, therefore improving overall circuit efficiency.

Pinout and Wiring:

• Anode (A): This is the positive side of the diode. Connect it to the input source where current enters the diode.
• Cathode (K): This is the negative side of the diode, typically marked by a colored band (often silver or black) on the diode body. Current flows out from this terminal.
• Functionality Note: The diode allows current to flow easily from the Anode to the Cathode (Forward Bias) but blocks current flow in the reverse direction (Reverse Bias).
