The 1SMB33CAT3G is a bidirectional Zener TVS diode from Littelfuse Inc., designed for general purpose transient voltage suppression. It features a reverse standoff voltage of 33V and a maximum clamping voltage of 53.3V, with a peak pulse power dissipation of 600W and a peak pulse current of 11.3A (8/20µs). The device is not intended for power line protection and is rated for operating temperatures from -65°C to 150°C.
This TVS diode is suitable for protecting sensitive electronics from voltage transients in a variety of applications. Its surface mount SMB package (DO-214AA) allows for compact PCB designs. The component has a capacitance of 265pF at 1MHz, which should be considered in high-frequency applications.
The 1SMB33CAT3G is RoHS3 compliant and has an MSL of 1 (unlimited), making it suitable for lead-free soldering processes. It is also REACH unaffected. However, note that compliance data is unverified. The part is commonly available from distributors such as DigiKey under alternate part numbers including 1SMB33CAT3GOSTR-ND.
