The 2SD718 is a powerful transistor that can be used in a wide range of electronic circuits for power amplification applications. Its high power and voltage handling capabilities, as well as its high gain, make it suitable for use in high-power audio amplifiers, power supplies, and motor control circuits. However, its slow switching speed and high output capacitance may limit its use in some high-performance applications.
Part Number: 2SD718
Function: 8A, 120V, 80W, High-power NPN Silicon Power Transistor
This is high-performance off-line PWM controller for low-power AC/DC chargers and power adapter.
The M5840 is a high-performance off-line PWM power switch used in low-power AC/DC battery chargers, power adapters, and LEDs. The constant voltage and constant current accuracy can be maintained within ±5% within the full voltage input range. The chip adopts the primary side feedback technology, so that the TL431 and optocoupler can be saved in the system application to reduce the cost.
1. Constant voltage and constant current accuracy up to 5%
2. Primary side control mode, no need for TL431 and optocoupler
