2SD1994ARA

Single Bipolar Transistors Overview

The Panasonic 2SD1994ARA is a silicon NPN epitaxial planar transistor designed for low-frequency power strengthening and drive applications. It features an MT-2-A1 package with radial taping supply capability. Key electrical parameters include a collector-emitter voltage of 50 V, a collector current of 1 A, and a collector power dissipation of 1 W. The device exhibits a low collector-emitter saturation voltage (VCE(sat)) and a transition frequency (fT) of 200 MHz. It is RoHS compliant and serves as the complementary component to the 2SB1322A.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'ARA' against official Panasonic documentation to confirm exact marking or packaging variations. Confirm current lifecycle status via manufacturer channels, as maintenance or discontinuation notices may apply to this series.

Single Bipolar Transistors Selection Notes

Select this component for low-frequency power drive tasks requiring high current handling up to 1 A. Ensure thermal management supports the 1 W dissipation rating at expected ambient temperatures. Verify that the 50 V breakdown voltage meets circuit requirements.

Single Bipolar Transistors Part Context

This part belongs to the Panasonic 2SD1994 series of NPN transistors. It is specifically engineered for low-frequency power applications and is paired with the 2SB1322A PNP transistor to form complementary pairs for push-pull configurations.

Single Bipolar Transistors Replacement Considerations

Consult official Panasonic substitution lists for verified equivalents. Generic replacements must match the 50 V VCEO, 1 A IC, and MT-2-A1 package constraints.
