The Littelfuse 1KSMB39CA is a bidirectional Zener TVS diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It offers a peak pulse power rating of 1000W (10/1000μs waveform) with a reverse standoff voltage of 33.3V and a clamping voltage of 53.9V at 18.6A peak pulse current. The device features a fast response time of less than 1.0ps from 0V to breakdown voltage, making it effective for high-speed transient suppression.
This TVS diode is suitable for general purpose applications including I/O interfaces, VCC bus protection, and data lines in telecom, computer, industrial, and consumer electronics. It is designed for surface mount assembly and is housed in a compact DO-214AA (SMB) package, which optimizes board space. The operating temperature range is -55°C to 150°C (junction).
The 1KSMB39CA is compliant with RoHS and halogen free requirements, and features matte tin lead-free plating. It is also characterized for IEC 61000-4-2 ESD protection (30kV air/contact) and IEC 61000-4-4 EFT protection. The plastic package is rated V-0 for flammability, and the device meets MSL level 1 per J-STD-020.
The reverse standoff voltage is 33.3V.
The clamping voltage is 53.9V at 18.6A peak pulse current.
The peak pulse current is 18.6A.
It is available in a DO-214AA (SMB) surface mount package.
