The 1KSMB22CA is a bidirectional TVS diode from Littelfuse designed to protect sensitive electronic equipment from voltage transients. It offers 1000W peak pulse power capability at 10/1000μs waveform, with a reverse standoff voltage of 18.8V and clamping voltage of 30.6V. The device features a fast response time of less than 1.0ps and ESD protection up to 30kV (air and contact) per IEC 61000-4-2.
This diode is suitable for surface mount applications in a DO-214AA (SMB) package. It is halogen free and Pb-free E3 certified, with an operating temperature range of -55°C to 150°C (junction). The 1KSMB series is ideal for protecting I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
Key specifications include a peak pulse current of 32.7A, bidirectional configuration, and compatibility with standard reflow soldering up to 260°C. The device meets MSL level 1 requirements and is packaged in a low-profile, flame-retardant plastic package.
The reverse standoff voltage is 18.8V.
The clamping voltage is 30.6V.
The peak pulse current is 32.7A.
The peak pulse power is 1000W.
The response time is typically less than 1.0ps from 0V to BV min.
The ESD rating is 30kV (air) and 30kV (contact) per IEC 61000-4-2.
The device is available in a DO-214AA (SMB) surface mount package.
