2SC4511

Single Bipolar Transistors Overview

The Sanken Electric 2SC4511 is a silicon NPN triple diffused planar transistor designed as the complement to the 2SA1725 PNP device. It features an absolute maximum collector current of 6A and a collector-emitter voltage rating of 80V. The component supports a maximum power dissipation of 30W at 25°C case temperature, with a junction temperature range from -55°C to +150°C. Electrical characteristics include a minimum DC current gain (hFE) of 50 and a typical transition frequency (fT) of 20MHz.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank suffix (O, P, or Y) required for your design, as these indicate different gain ranges. Confirm that the TO-220F package thermal management meets your system's heat dissipation requirements. Ensure the operating voltage does not exceed the 80V VCEO limit under all transient conditions.

Single Bipolar Transistors Selection Notes

Select this component when a high-current NPN switch is needed to match the 2SA1725 PNP transistor in push-pull configurations. Consider the 30W power dissipation capability and the need for adequate heatsinking to maintain performance within the specified thermal limits during continuous operation.

Single Bipolar Transistors Part Context
