The BD13616S is a PNP epitaxial silicon bipolar junction transistor manufactured by Fairchild Semiconductor, now part of onsemi. It is designed for medium power linear and switching applications. The device features a through-hole TO-126-3 package configuration. Key electrical specifications include a collector-emitter voltage rating of 45 V and a continuous collector current capacity of 1.5 A. The maximum power dissipation is rated at 1.25 W. This component belongs to the BD136 series, offering reliable performance for general-purpose amplification and switching tasks in electronic circuits.
Verify manufacturer attribution carefully as Fairchild Semiconductor was acquired by onsemi; datasheets may bear either brand. Confirm package type is TO-126-3 for through-hole implementation. Check RoHS compliance status against specific revision. Ensure application requirements match the 45V and 1.5A limits. Validate availability as some distributors list it while others indicate limited supply or obsolete status.
Select this component when a PNP transistor with moderate current handling is required for through-hole designs. Compare against NPN equivalents if circuit topology demands opposite polarity. Consider thermal management capabilities given the 1.25W dissipation limit. Verify compatibility with existing board space constraints for the TO-126-3 footprint. Review datasheet for hFE variations across temperature ranges.
The BD13616S is part of the broader BD136 family of PNP transistors produced by Fairchild Semiconductor. This series includes related devices such as the BD135, BD137, and BD139, which offer complementary NPN configurations. The BD136 series is widely recognized for its utility in medium-power applications. While some variants in the series are marked obsolete, the BD13616S remains referenced in current component databases.
