Here's a concise introduction to SMBJ43A: The Taiwan Semiconductor Corporation's SMBJ43A is a surface-mount transient voltage suppressor diode designed for surge protection in electronic circuits. With a peak pulse power dissipation of 600 watts, breakdown voltage of 43 volts, and low clamping voltage, this device safeguards sensitive equipment against voltage transients caused by lightning, electrostatic discharge (ESD), and other sudden events. The SMBJ43A is ideal for telecommunications, industrial automation systems, automotive electronics, and power supplies due to its fast response time and high surge absorption capability. Its compact surface-mount package (SMB) makes it suitable for use in a variety of applications where space is limited.
According to the product information, the SMBJ43A features are:
The package type of SMBJ43A is Surface Mount (SMB).
The SMBJ43A has a single pin, which is the anode. The cathode is internally connected to the package lead. When the voltage exceeds the breakdown voltage (43V), the diode conducts and clamps the voltage to a lower level, protecting the circuit from damage.
The manufacturer of the SMBJ43A is Taiwan Semiconductor Corporation (TSC). It is a semiconductor components manufacturer that specializes in producing semiconductors, including diodes, transistors, and thyristors. TSC provides a wide range of products for various applications, including power supplies, industrial automation systems, automotive electronics, and telecommunications equipment.
The SMBJ43A transient voltage suppressor diode is commonly used in applications such as telecommunications equipment, industrial automation systems, automotive electronics, and power supplies to protect sensitive devices from voltage spikes and transients. Its fast response time and high surge absorption capability make it ideal for safeguarding circuits from overvoltage events.
Based on Taiwanese manufacturer Taiwan Semiconductor Corporation (TSC), SMBJ43A's equivalent products include:
These devices share similar specifications, such as peak pulse power dissipation, breakdown voltage, and clamping voltage. However, please note that equivalent products may have slight variations in performance or characteristics.
