The 1KSMB51A is a unidirectional TVS diode from Littelfuse, part of the 1KSMB series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events.
Key specifications include a reverse standoff voltage of 43.6V, a minimum breakdown voltage of 48.5V, and a clamping voltage of 70.1V at a peak pulse current of 14.3A. It offers 1000W peak pulse power capability (10/1000µs waveform) with a fast response time typically less than 1.0ps.
The device is housed in a surface mount DO-214AA (SMB) package with matte tin lead finish. It supports a wide operating temperature range of -55°C to 150°C and is suitable for high temperature reflow soldering up to 260°C. The component is halogen free and RoHS compliant.
The reverse standoff voltage is 43.6V.
The minimum breakdown voltage is 48.5V.
The maximum clamping voltage is 70.1V at a peak pulse current of 14.3A.
The peak pulse power is 1000W (1kW) for a 10/1000µs waveform.
The package is DO-214AA (SMB) for surface mount applications.
The operating junction temperature range is -55°C to 150°C.
The datasheet claims RoHS compliance and halogen free status, but this is unverified.
