BC635_J35Z is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists onsemi. Its product description is TRANS NPN 45V 1A TO-92-3. Review the specifications below when checking this part for your BOM.
The BC635_J35Z is an NPN medium power transistor manufactured by onsemi. It utilizes a silicon epitaxial planar process and is housed in a TO-92 (TO-226AA) three-lead plastic package with formed leads. The device is rated for a collector-emitter voltage of 45 V and a continuous collector current of 1 A. It features a maximum power dissipation of 0.8 W at 25°C ambient temperature. The component supports a junction temperature range from -55°C to +150°C and is classified as obsolete.
This part number is officially marked as obsolete by the manufacturer. Verify availability through secondary market channels or authorized distributors holding remaining stock. Confirm that the specific J35Z suffix corresponds to the required bulk packaging format. Ensure compatibility with existing PCB footprints before procurement, as active replacements may require design adjustments.
Select this component only if legacy compatibility is mandatory due to its obsolete status. Evaluate alternative NPN transistors with similar 45 V and 1 A ratings for new designs. Consider package constraints and thermal management requirements when substituting. Verify that the replacement meets the same electrical characteristics and physical dimensions to ensure seamless integration.
The BC635 series belongs to onsemi's lineup of general-purpose NPN medium power transistors. These devices are widely used in consumer electronics and industrial equipment. The BC635 serves as a complement to P-channel counterparts like the BC636. Its TO-92 package provides a compact solution for low-to-medium power applications requiring robust switching capabilities.
Public confirmed substitute part numbers include BC636TFR.
