S15JC R7G Discrete Semiconductor Products

Diodes are fundamental components of the modern electrical systems and a crucial device for controlling the flow of electrical current. The S15JC R7G is a Single Rectifier Diode with high temperature plastic package, typically used in the power switching applications. It has an ultra-fast recovery time with half-wave peak-forward current rating of 7 Amps, reverse voltage rating of 400 Volts and blocking voltage of 500 Volts.

S15JC R7G Applications

S15JC R7G Diode is a fast switching device with low forward voltage drop. It is used in various applications like motor pulse generators, diode rectifiers, power switching circuits, power supplies, DC to DC converters, control circuits and solid-state relays. It is suitable for applications that require low noise fast switching, like Uninterruptible Power Supply (UPS) systems, as it has high surge capacity and fast recovery time.

The S15JC R7G diode is popularly used in welding applications, as well as in portable air conditioners, power inverters and automotive cooling fans. It is also used as a replacement component for obsolete rectifier units.

S15JC R7G Working Principle

The S15JC R7G diode works on the principle of rectification, which means it converts AC input into DC output. It is a unidirectional device, meaning it allows electrical current to pass in only one direction. The diode has two terminals, one positive (anode) and one negative (cathode). When the anode is at a positive voltage with respect to the cathode, the forward current will be allowed to pass through the diode and no current will flow if the voltage is reversed. Thus, it acts as a switch, either allowing or blocking the current, depending on the polarity of the two voltage-sources.

S15JC R7G diode also acts as a protection device for other circuit components, as it allows the current to pass only in one direction and prevents any reverse current from flowing. This helps protect the device and the circuit from damage.

Conclusion

The S15JC R7G Diode is a rectifier unit with a high temperature plastic package. It has a 7 Amps half-wave peak-forward current rating, reverse voltage rating of 400 Volts, and blocking voltage of 500 Volts. It is primarily used for power switching applications, as well as for replacing an obsolete rectifier. It works on the principle of rectification and prevents any reverse current from reaching the device and circuit.
