The SD045SA30A(B) is a high-performance Transient Voltage Suppressor (TVS) Diode manufactured by SMC DIODES. Supreme Components International is an authorised distributor of SMC DIODES components. This diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, ESD, and EFT. It features a standoff voltage of 30V and a peak pulse power dissipation of 400W. The SD045SA30A(B) is available in a compact DO-214AC (SMA) package, making it suitable for space-constrained applications. Its fast response time and low clamping voltage ensure effective protection against overvoltage events. This TVS diode is commonly used in automotive, industrial, and consumer electronics applications to enhance system reliability and prevent damage from voltage surges.
