ZHCSJJ0C August 2000 – March 2024 BUF634
PRODUCTION DATA
The BUF634 delivers up to ±250-mA continuous output current. Internal circuitry limits output current to approximately ±350 mA; see Figure 6-10. For many applications, however, the continuous output current is limited by thermal effects.
The output voltage swing capability varies with junction temperature and output current; see Figure 6-14. Although all four package types are tested for the same output performance using a high speed test, the higher junction temperatures with the DIP and SO-8 package types often provide less output voltage swing. Junction temperature is reduced in the TO-263 surface-mount power package because this package is soldered directly to the circuit board. The TO-220 package used with a good heat sink further reduces junction temperature, allowing maximum possible output swing.
