2STW1695

Single Bipolar Transistors Overview

The 2STW1695 is a high power PNP epitaxial planar bipolar transistor manufactured using BiT-LA technology. It features a collector-emitter voltage (VCEO) of -140 V, a continuous collector current (IC) of -10 A, and total dissipation (Ptot) of 100 W at Tc = 25 °C. The device exhibits a typical transition frequency (fT) of 20 MHz and is fully characterized at 125 °C. It is housed in a TO-247 tube package.

Single Bipolar Transistors Feature Summary

• High breakdown voltage with VCEO rated at -140 V
• Good gain linearity behavior due to BiT-LA technology
• Complementary design paired with the 2STW4468 NPN transistor

Single Bipolar Transistors Applications

• High fidelity audio frequency amplifiers (70 W to 100 W)

Single Bipolar Transistors Procurement Notes

Verify component status as the datasheet explicitly identifies the 2STW1695 as an obsolete product. Confirm availability through secondary market channels or authorized distributors holding remaining stock. Ensure the TO-247 tube packaging matches system requirements for surface mounting or through-hole assembly processes.

Single Bipolar Transistors Selection Notes

Select this component for linear amplifier applications requiring high gain linearity and robust thermal performance. The BiT-LA technology ensures stable operation up to 125 °C junction temperature. Consider the complementary 2STW4468 for push-pull configurations. Verify that the -140 V rating meets circuit voltage headroom needs.
