TMP464: MMBT3904 transistor selection

Hi Sir,

Due to space limit, customer would like to use below device as MMBT3904 transistor, is that ok?

Anything need to modify?



  • Hey Patrick,

    Yes this should be fine. Per the section 8.2.1 of the datasheet, Either NPN or PNP transistors can be used, as long as the base-emitter junction is used as the remote temperature sensor. NPN transistors must be diode-connected. PNP transistors can be either transistor- or diode-connected.
