Application field and Working principle
1SMA4741TR Zener diodes are widely used in electronic circuits to maintain a predetermined voltage at the cathode. This is done through a process known as Zener breakdown, where the diode is stressed above its reverse breakdown voltage and then restricts the current flow once that voltage has been surpassed. This diode is also used as a voltage regulator since it can regulate the voltage at its cathode, regardless of the voltage at its anode. It is also used to limit the maximum voltage that can be applied to a circuit, and to protect circuits by diverting harmful currents away from them.
The 1SMA4741TR diode is designed to withstand a reverse voltage of -41V and a power dissipation of 4.7W. It has a storage temperature range of -65°C to + 125°C and a junction temperature of +155°C. This device has a maximum allowable secondary leakage current (IS) of 20 μA and a safe operating area (SOA) specification of 3.5V at 30mA. It is also capable of handling up to 10MHz of frequency for pulse waveform applications.
In terms of application, 1SMA4741TR is ideal for low-power voltage regulation and for over-voltage protection. It is commonly used in consumer electronic products, such as air conditioners, television sets, and refrigerators. It is also suitable for automotive application, such as in the voltage regulator circuit of the car. This diode can also be used for pulse waveform applications due to its high frequency protection.
In summary, 1SMA4741TR is a single Zener diode suitable for low-power voltage regulation and over-voltage protection in consumer electronic products and automotive applications. It is designed to withstand a reverse voltage of -41V and a power dissipation of 4.7W, with a maximum allowable secondary leakage current of 20 μA. With its solid characteristics and capabilities, 1SMA4741TR is a reliable and powerful diode, with uses across a vast range of circuits.
