The 1KSMB47A is a unidirectional Zener TVS diode from Littelfuse Inc., designed for general purpose transient voltage suppression in sensitive electronic circuits. It offers a reverse standoff voltage of 40.2V and a clamping voltage of 64.8V, with a peak pulse current rating of 15.4A. The device dissipates up to 1000W of peak pulse power under a 10/1000μs waveform.
This component is surface mount capable, housed in a compact DO-214AA (SMB) package, and operates over a temperature range of -55°C to 150°C. It is suitable for protecting I/O interfaces, VCC buses, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics applications.
The 1KSMB47A is part of the 1KSMB series, which bridges the gap between 600W and 1.5kW surge ratings, offering high surge capability in a low-profile package.
The clamping voltage is 64.8V.
The peak pulse current is 15.4A.
The reverse standoff voltage is 40.2V.
It comes in a DO-214AA (SMB) surface mount package.
The operating temperature range is -55°C to 150°C.
