BD1396S

Overview

The BD1396S is an NPN silicon epitaxial planar transistor manufactured by onsemi. It belongs to the BD139 series and is designed for audio amplifiers and drivers utilizing complementary or quasi-complementary circuits. The device features a maximum collector current of 1.5 A, a collector-emitter voltage (VCEO) of 80 V, and a power dissipation rating of 12.5 W. It operates within a temperature range of -55°C to +150°C and utilizes a TO-126 package.

Feature Summary

• Epitaxial planar construction for reliable performance in audio applications
• Designed for use in complementary and quasi-complementary circuit configurations
• High DC current gain selection available for consistent amplifier operation

Applications

• Audio amplifier stages
• Driver circuits for audio systems
• Complementary output stages

Procurement Notes

Verify the specific suffix '6S' against official datasheets to confirm pinout and gain grouping. Confirm RoHS compliance status as indicated in manufacturer documentation. Ensure the TO-126 package matches your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when designing audio amplifiers requiring an NPN driver with 1.5 A capability. Compare VCEO ratings against supply voltages to ensure adequate headroom. Consider thermal management solutions given the 12.5 W power dissipation limit in the TO-126 package.

Part Context

The BD1396S is part of the BD139 family, which includes complementary PNP types like the BD140. This series is widely used in general-purpose audio applications due to its balanced electrical characteristics and robust packaging. The '6S' suffix typically denotes specific gain binning or manufacturing lot codes defined by onsemi.

Replacement Considerations

Direct substitutes include other BD139 variants with compatible gain ranges. Verify pinout compatibility between TO-126 packages from different manufacturers. Check if alternative NPN transistors meet the 1.5 A current and 80 V voltage requirements.
