UF1502S-B is a diode rectifier utilizing advanced Planar Diffused Junction Technology with a TO-220F package which offers high reliability and low power dissipation. It is a single-phase, half wave, 60-100V forward voltage, 150A current diode rectifier suitable for DC power supply, inverters and motor control.

Applications

UF1502S-B is designed to offer cost effective solutions in DC power supplies, Inverters, Motor Control, Welding Control and many other automotive and industrial applications.

UF1502S-B diode rectifier is used in low cost power supplies, such as uninterruptible power supplies (UPS) and switches mode power supplies (SMPS). It is used in automotive applications such as alternators, power converters and general electronic load applications. Inverter applications include air conditioners, refrigerators, microwave ovens, lighting, and other small home appliances. In motor control applications, such as motor starters, starters and fans, it is used as a rectifier in order to provide power to the motor. It is also suitable for welding applications, such as welding machines or arc welding.

Working principle

UF1502S-B operates by converting AC power to DC by blocking current when the voltage is greater than the forward voltage value and allowing current to flow when the voltage is less than the forward voltage. The diode utilizes a Nitride passivated layer for blocking current, which gives the diode a wide operating temperature range of -40°C to +85°C and peak repetitive reverse voltage of 600V under junction temperature up to 25°C.

The UF1502S-B utilizes Planar Diffused Technology which provides high current and low forward voltage drops, resulting in higher power efficiency and system reliability. The combination of high current carrying capability and low forward voltage drop makes it suitable for low power supplies and other power applications.

The diode has a fast recovery time, which is important in high frequency applications. Its thermal design helps to ensure long term reliability of the system, with a maximum average forward current of 150A.

In conclusion, UF1502S-B diode rectifier is an efficient and reliable solution for DC power supplies, Inverters, Motor Control, Welding Control and many other automotive and industrial applications. It provides high reliability and low power dissipation due to its planar diffused junction technology and Nitride Passivation layer.
