The 1KSMB43A is a 1000W unidirectional TVS diode from Littelfuse Inc. designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
Key electrical specifications include a reverse standoff voltage of 36.8V, a minimum breakdown voltage of 40.9V, and a maximum clamping voltage of 59.3V at 16.9A peak pulse current (10/1000µs waveform). The device offers a fast response time of less than 1.0 ps and features a glass passivated chip junction for reliability.
The 1KSMB43A is housed in a DO-214AA (SMB) surface mount package and is rated for operating temperatures from -55°C to 150°C. It is RoHS compliant, halogen free, and has a Pb-free E3 termination finish. The part is suitable for general purpose applications including I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
The reverse standoff voltage (working voltage) is 36.8V.
The minimum breakdown voltage is 40.9V.
