KSB1015YTU

Single Bipolar Transistors Overview

The KSB1015YTU is a PNP epitaxial silicon transistor designed for low frequency power amplifier applications. It features a TO-220-3 Fullpack package with an isolated collector. Key electrical ratings include a maximum collector current of 3 A, a collector-emitter breakdown voltage of -60 V, and a collector power dissipation of 25 W at 25°C case temperature. The device exhibits a minimum DC current gain (hFE) of 20 at 3 A and 60 at 0.5 A, with a transition frequency of 9 MHz.

Single Bipolar Transistors Feature Summary

• PNP epitaxial silicon construction optimized for low frequency power amplification
• Low collector-emitter saturation voltage to minimize conduction losses
• Isolated collector flange mount design for efficient thermal management

Single Bipolar Transistors Applications

• Low frequency power amplifier circuits
• General purpose switching applications requiring high current handling
• Complementary driver stages in audio or RF power systems

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix YTU corresponds to the TO-220-3 Fullpack configuration and lead-free status as documented in the official onsemi datasheet. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure proper thermal interface material is selected for the isolated flange mount package to maintain junction temperatures within the specified 150 °C limit during operation.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring a robust PNP power transistor with a 3 A continuous collector current capability. The -60 V collector-emitter voltage rating suits applications operating below this threshold. Consider the 25 W power dissipation limit and ensure adequate heatsinking is provided to maintain the case temperature at or below 25 °C for full rated performance, or apply derating factors for higher ambient conditions.

Single Bipolar Transistors Part Context

The KSB1015 series belongs to onsemi's lineup of general-purpose PNP power transistors. Manufactured using epitaxial silicon planar technology, these devices are engineered for reliability in power amplification roles. The KSB1015YTU variant specifically denotes the tube packaging format within the broader KSB1015 product family, sharing identical electrical characteristics with other suffixes while differing only in shipping configuration.

Single Bipolar Transistors Replacement Considerations

Direct substitutes must match the PNP polarity, 3 A current rating, and -60 V voltage rating. Verify pinout compatibility for the TO-220-3 Fullpack package. Check if alternative manufacturers offer equivalent hFE classifications and saturation voltages to ensure circuit performance parity without redesign.
