Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank suffix (O, P, or Y) required for your circuit's gain requirements before ordering. Confirm that the MT-100 (TO-3P) package dimensions align with your heatsink interface specifications. Ensure proper isolation from the mounting surface if electrical insulation is necessary for your chassis ground configuration.

Single Bipolar Transistors Selection Notes

Select this component when high current handling and substantial DC gain are required in a single package. The complementary nature with the 2SD2560 makes it ideal for push-pull output stages where matching characteristics are critical. Consider the thermal derating curves for ambient temperatures exceeding standard operating ranges.

Single Bipolar Transistors Part Context

This device belongs to Sanken's lineup of high-power bipolar junction transistors utilizing epitaxial planar technology.
