Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix ATV2P against official ROHM documentation to confirm packaging details and hFE binning. Confirm supply status as this component may be subject to production lifecycle changes. Ensure compatibility with standard TO-252 footprints during PCB layout. Validate thermal management requirements for the specified power dissipation limits under actual operating conditions.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high voltage handling and moderate current capacity in a compact surface-mount package. Consider its low output capacitance for high-frequency signal integrity. Evaluate thermal performance relative to the 1 W (free air) and 10 W (case mounted) dissipation ratings. Compare against complementary PNP types like the 2SB1275 for push-pull configurations.
