Shindengen S34160 is a single rectifier diode pack composed of 3 Fast Recovery Rectifier Diodes, with a total output current capacity of 16A and a maximum peak reverse voltage (VRM) of 600V. This diode is also suitable for use in medium-to-high frequency, medium-current DC motor applications, such as alternator circuit regulators, switching mode power supplies (SMPS), or various rectifier circuits. It is also suitable for various DC output switching applications. In order to make use of this device, it is important to understand the application field and working principle of the S34160.

Application Field

The Shindengen S34160 is designed as an all-around diode rectifier with many applications. These include providing rectification, free-wheeling diodes, and protection components working under high voltage and current. This device is ideal for DC output rectification, high frequency and medium-current rectification, DC motor applications, and reverse protection in switching mode power supplies (SMPS). This device is well-suited for any project relying on a high-capacity rectifier diode with a high peak reverse voltage rating for protection and current-limiting.

Working Principle

The S34160 is a single rectifier diode pack composed of 3 Fast Recovery Rectifier Diodes. The device is exposed to maximal reverse peak currents and voltages of 16A and 600V, respectively. Therefore, it is suitable for application in medium-to-high frequency and high current DC motor applications. The overall working principle of the device is pretty straightforward — it limits the current that passes through the device by blocking any reverse flow of current. Its purpose is to regulate the voltage and current going in and out of a circuit. When the device is connected in an AC circuit, the current gets pulsed, with the diodes producing higher output voltages and lower power losses.

The device is composed of three Fast Recovery Rectifier Diodes (FRRs) with a maximum peak reverse voltage (VRM) of 600V. When the device is presented with alternating current, each diode starts a single pulse release and produces a single, unified output. This unified output is the result of a combination of certain aspects of the diodes\' characteristics, including their isolation from one another, their reverse voltage, direct recovery time, and forward voltage drop.

When the current flows from the positive terminal of the power supply to the negative power supply terminal, the diode conducts and the current is passed through the circuit. When the voltage rises above the peak reverse voltage rating of the diode, it is blocked and no current passes through the circuit. This is the device’s clamping effect; it prevents any further increase in voltage beyond the peak reverse voltage.

At low temperatures, the forward characteristics of the S34160 are stabilized by the diodes’ junction temperature. The forward voltage drop is significantly lower at low temperatures, thus decreasing the power losses of the device. The reverse recovery time of the power diodes is also stabilized at all temperatures. This helps the device to operate reliably without any risk of voltage overshoots or current surges.

In conclusion, the Shindengen S34160 is an all-around diode rectifier designed for use in rectification and protection applications that require high-current capacity. It is composed of three fast recovery rectifier diodes with a maximum peak reverse voltage of 600V and a total output current capacity of 16A. The device works by blocking any reverse flow of current and regulating voltage and current going in and out of a circuit.
