BD179G

Overview

The BD179G is a plastic medium-power silicon NPN transistor manufactured by onsemi. It features a collector-emitter voltage (VCEO) of 80 Vdc and supports a continuous collector current (IC) of 3.0 Adc. The device provides a total power dissipation (PD) of 30 W at a case temperature of 25°C, with a thermal resistance junction-to-case (RθJC) of 4.16°C/W maximum. It operates within a junction temperature range of –65 to +150°C. The component utilizes a TO-225 package and is designed for audio amplifier applications.

Feature Summary

Complementary pairing with the BD180 PNP transistor
High DC current gain characteristics
Lead-free construction compliant with RoHS standards

Applications

Audio amplifiers utilizing complementary circuits
Audio amplifiers utilizing quasi-complementary circuits
Driver stages in 5.0 to 10 Watt audio systems

Procurement Notes

Verify the specific ordering suffix 'G' confirms lead-free packaging status as documented in the official datasheet. Confirm that the TO-225 package style matches the required pinout configuration for the target circuit design. Ensure compliance with the stated operating temperature limits during system integration planning.

Selection Notes

Select this component when designing medium-power NPN stages requiring 3 Amperes of continuous current handling. The 80 Volt rating suits low-voltage audio driver applications. Verify thermal management capabilities align with the 30 Watt dissipation limit and the specified junction-to-case thermal resistance for reliable operation.

Part Context

This device belongs to the BD179 series of plastic medium-power silicon NPN transistors produced by onsemi. It is engineered specifically for use in audio amplifier topologies. The part number BD179G denotes the standard device variant packaged in a TO-225 housing with lead-free finish specifications.
