Single Bipolar Transistors Procurement Notes

Verify the specific suffix (e.g., 'P') against official documentation, as it may indicate packaging or variant details not explicitly defined in the base datasheet. Confirm current lifecycle status on the manufacturer website, as maintenance/discontinued classifications change. Ensure compliance with RoHS Directive requirements for your region. Request the latest Product Standards before finalizing designs to account for potential specification updates.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring high current switching with minimal voltage drop. Consider the thermal resistance curves when designing heat sinks, as dissipation drops significantly without one. Verify that the required hFE rank meets the gain needs of the driving circuit. Ensure the operating environment stays within the specified junction temperature range to maintain reliability.

Single Bipolar Transistors FAQ

What is the difference between the 2SB0948 and 2SB0948A?

The primary difference is the collector-emitter voltage rating. The 2SB0948 has a VCEO of -20V, while the 2SB0948A supports -40V. Both share similar current and power dissipation ratings.

How is the hFE gain classified?

The forward current transfer ratio (hFE) is classified into ranks R, Q, and P based on the value at IC = -3A. Rank R covers 60-120, Q covers 90-180, and P covers 130-260.

What is the recommended operating junction temperature?

The maximum junction temperature (Tj) is 150°C. The storage temperature range is -55°C to +150°C. Electrical characteristics are typically guaranteed at a case temperature of 25°C ± 3°C.
