MicroelectronicsThe 1SMA4741A is a Zener diode manufactured by Jingdao Microelectronics. It is a surface mount, RoHS compliant diode which is used to regulate the voltage in circuits. It features a maximum breakdown voltage of 27 volts and is capable of withstanding a peak current of up to 1.5 A. The Zener diode is packaged as an SMA (Surface Mount Assembly) device. The device is designed with a glass passivation and a gold-plated metallisation layer which provides good thermal/mechanical stability, low thermal resistance, and low parasitic capacitance. The 1SMA4741A is suitable for a wide variety of applications such as power management, voltage regulation, transient protection, and more.
