Procurement Notes
Verify the specific suffix configuration when ordering. The -TP suffix indicates tape and reel packaging containing 1000 pieces per reel. The -S suffix designates the hFE gain ranking range of 170 to 340. Ensure compliance with RoHS standards and confirm halogen-free requirements if applicable by checking for additional suffixes. Purchase only from authorized distributors to guarantee genuine parts and traceability.
Selection Notes
Select this component for designs requiring an NPN power transistor with a 1 A current rating and 25 V breakdown voltage. The SOT-89 package offers a compact form factor suitable for space-constrained layouts. Consider the hFE ranking (-S) to ensure sufficient current gain for the specific drive requirements. Verify thermal management capabilities as the device dissipates up to 500 mW.
