Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TL' corresponds to the tape-and-reel packaging configuration containing 2500 units per basic ordering unit. Confirm that the component meets the required RoHS compliance standards for your manufacturing process. Ensure the CPT-3 footprint matches your PCB layout design constraints before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when designs require high-voltage handling capabilities exceeding standard low-voltage transistors. The -400V rating makes it suitable for primary-side switching in offline power supplies. Consider the thermal dissipation limits of 1W at 25°C ambient temperature and ensure adequate heat sinking or copper area on the PCB to maintain junction temperatures within the specified -55°C to +150°C range.
