General purpose switching

Procurement Notes

Verify component authenticity through official Sanken Electric channels or authorized distributors. Confirm that the part matches the MT-200 package dimensions and pinout specifications. Ensure compliance with RoHS standards if required by your specific application environment. Review the datasheet for absolute maximum ratings to prevent operational damage during integration.

Selection Notes

Select this component for designs requiring high current handling capabilities up to 17 A. Consider the thermal management requirements given the power dissipation characteristics in the MT-200 package. Evaluate the hFE rank options (O, P, Y) if specific gain ranges are necessary for your circuit design. Note that the manufacturer does not recommend new designs using this part.

Part Context

This transistor belongs to Sanken Electric's lineup of silicon NPN triple diffused planar transistors. It serves as the complementary pair to the 2SB1648 PNP transistor. The device is engineered for reliability in power handling applications, utilizing a specific planar structure to manage heat and electrical stress effectively in audio and regulation circuits.

Replacement Considerations

The datasheet explicitly states that this component is not recommended for new designs. Designers should consult current Sanken Electric product catalogs for modern alternatives suitable for new development projects.
