Introduction to BAS40,235

BAS40,235 is a single-purpose rectifying diode designed for use in a wide range of applications, including commercial and industrial products, as well as communications and automotive applications. It is manufactured by Vishay Semiconductors.

BAS40,235 Application Field

BAS40,235 is suitable for a variety of switched-mode power supplies, including TV and PC monitor power supplies, computer power supplies, and AC adapters. Additionally, it is well-suited for automotive electronics, power supplies, and high-speed rectifiers. Other applications include household light dimmers, medical equipment, and battery chargers. The diode is able to withstand up to 600V and is rated for a 10kHz switching frequency.BAS40,235 is particularly well suited for pulse width modulation (PWM) control circuits. It demonstrates low forward voltage drop, fast switching speeds, and an optimized reverse recovery time.

BAS40,235 Working Principle

BAS40,235 is a zero-reverse-recovery, fast-sine rectifying diode designed to overcome the limitations of traditional rectifiers. It features an optimized silicon-controlled rectifier (SCR) structure, which results in quick switching time and low thermal impedance.The BAS40,235’s optimized SCR structure gives it an inherently greater forward voltage drop, which helps to reduce energy loss and improve efficiency. Additionally, its fast switching speed ensures that it is able to rapidly switch current, allowing it to support frequencies up to 10kHz. It is also able to handle peak reverse voltages up to 600V and can withstand more than five million switching cycles. Due to its zero-reverse recovery time and low dissipation factor, the diode runs at a low temperature even under heavy loads.

Conclusion

BAS40,235 is a high-speed, zero-reverse-recovery diode designed for use in a wide range of switched-mode power supplies, including TV and computer power supplies, as well as communications and automotive applications. Its optimized SCR structure gives it superior forward voltage drop and switching speeds, with a peak reverse voltage of up to 600V and the ability to withstand more than five million switching cycles. Additionally, its low thermal impedance and low dissipation factor make it an ideal choice for applications that require extended lifetimes and high efficiency.
