Application Information – Recommended MOSFETs
SE stands for Single Ended Outputs and BR stands for Bridged Output
MOSFETs Under Evaluation
The following MOSFETs appear to be suitable for use with the TP2150B, and we are waiting for
samples to evaluate. Most of these devices come from the same “family” or generation, as other
recommended MOSFETs. However, experience tells us that we cannot recommend any devices
until we have received samples and fully tested them.
