Overview
The BC817-16W is an NPN general-purpose transistor from the Panjit International Inc. BC817-16W Series, designed for amplifier applications. It features a planar epitaxial silicon construction housed in a SOT-323 plastic package. The device supports a continuous collector current of 500 mA and a total power dissipation of 300 mW. Key electrical parameters include a collector-emitter breakdown voltage (V(BR)CEO) of 45 V, a DC current gain (hFE) range of 100 to 250 at Ic=100mA, and a collector-base capacitance of 7.0 pF. It operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- NPN epitaxial silicon planar design suitable for general-purpose amplification
- Compliant with EU RoHS 2011/65/EU directive using halogen-free green molding compound
- Solderable terminals meeting MIL-STD-750 Method 2026 standards
Applications
- General purpose amplifier circuits
- Medium power switching applications
Procurement Notes
Verify the specific ordering suffix against official Panjit documentation to confirm packing type and reel specifications. Ensure compliance with RoHS 2011/65/EU requirements if applicable to your manufacturing process. Confirm that the application does not involve life-saving or high-reliability equipment, as these products are not authorized for such uses. Request lot numbers for tracking purposes when addressing quality complaints.
Selection Notes
Select this component for designs requiring an NPN transistor with a 45 V collector-emitter voltage rating and up to 500 mA continuous current capability. The SOT-323 package is appropriate for space-constrained surface-mount layouts. Consider the hFE range of 100–250 for biasing calculations. Verify thermal resistance constraints, as the junction-to-ambient thermal resistance is 420 °C/W under minimum pad mounting conditions on FR-5 boards.
Part Context
This part belongs to the BC817 series of NPN general-purpose transistors manufactured by Panjit International Inc. The series includes variants with different current gain rankings, specifically the BC817-16W, BC817-25W, and BC817-40W. All variants share the same physical SOT-323 package and maximum ratings but differ in their DC current gain specifications.
Replacement Considerations
Panjit datasheets do not list confirmed substitute part numbers. Cross-reference with other manufacturers' BC817-16 equivalents only after verifying pinout compatibility, voltage ratings, and current gain ranges.
