The SD055SA45A(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 specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a standoff voltage of 55V and a surge capability of 45A, the SD055SA45A(B) offers robust protection in a compact DO-214AA (SMB) package. Its fast response time and low clamping voltage ensure effective transient suppression, safeguarding downstream components from damage. This TVS diode is suitable for a wide range of applications, including automotive, industrial, and consumer electronics.
