The peak pulse current tolerance is 40A at 8.3 ms while the junction temperature can be as high as 175°C. In addition, the thermal resistance is 40°C/W and the capacitance is as low as 200 pF.

Applications

1SR154-400TE25 is mainly used in power rectifying, voltage regulation, and voltage protection applications. Due to its high reverse voltage rating, the rectifier can be used for high-voltage circuits. This rectifier can also be used for RF noise control in communication systems. It is also ideal for automotive, computer, and telecom applications.

Working Principle

The working principle of 1SR154-400TE25 is based on the interaction of the forward and reverse bias junction. When this junction is forward biased, current is allowed to flow through it. When it is reverse biased, the current is prevented from flowing. This enables the rectifier to function as a power rectifier and a voltage regulator.The reverse bias voltage applied to 1SR154-400TE25 generates an electric field across the junction. This electric field increases in strength as the applied voltage increases. The increase in strength of the electric field causes a depletion region to be created between the two junctions. This causes a high resistance to current flow, which is what prevents current from flowing through the junction in reverse bias.

Conclusion

In conclusion, 1SR154-400TE25 is a single junction rectifier made up of diodes. It has reversed voltage rating of 400V, forward voltage of 6.2V, peak current of 1A and continuous current of 0.1A. The rectifier is mainly used for power rectifying, voltage regulation, and voltage protection applications. Finally, its working principle is based on electric fields created by the reverse bias junction.
