The 1KSMB33A is a unidirectional TVS (transient voltage suppression) diode from Littelfuse Inc., part of the 1KSMB series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. The device offers a peak pulse power dissipation of 1000W (10/1000μs waveform) and features a fast response time of typically less than 1.0ps from 0V to breakdown voltage minimum.
Key electrical specifications include a reverse standoff voltage of 28.2V, a clamping voltage of 45.7V at a peak pulse current of 21.9A, and a peak forward surge current rating of 120A. The device is unidirectional with one channel and is not intended for power line protection. It is rated for general purpose applications.
The 1KSMB33A is housed in a surface mount DO-214AA (SMB) package with a matte tin lead-free termination finish. It operates over a junction temperature range of -65°C to 150°C and has a storage temperature range of -65°C to 175°C. The device is halogen free and RoHS compliant, with a Pb-free E3 rating.
The clamping voltage is 45.7V at a peak pulse current of 21.9A.
The peak pulse power dissipation is 1000W (1kW) for a 10/1000μs waveform.
The reverse standoff voltage is 28.2V.
The device is available in a surface mount DO-214AA (SMB) package.
The junction operating temperature range is -65°C to 150°C.
Yes, it provides ESD protection up to 30kV (air and contact) per IEC 61000-4-2.
