Product details

Any procurement for this line must go through the independent surplus and broker channel.

Key ratings for replacement matching

The STF715 is an NPN transistor rated for a collector-emitter breakdown voltage of 80 V and a maximum collector current of 1.5 A. Saturation voltage is 500 mV at 100 mA base current and 1 A collector current. Transition frequency is 50 MHz. Maximum power dissipation is 1.4 W.

The STF715 is supplied in the SOT-89-3 package (also designated TO-243AA), a surface-mount package with three leads.

Frequently asked questions

What is the replacement for STF715?

No official replacement or successor is listed for the STF715 in the available records. A functionally equivalent NPN transistor in the same SOT-89-3 package with comparable ratings (80 V Vceo, 1.5 A Ic, 50 MHz fT) would need to be evaluated for pin-compatibility and electrical fit. The STF717 is a candidate for comparison, but its specifications are not detailed here.
