Overview
The 2SD415-AZ is an NPN silicon small signal bipolar junction transistor manufactured by Renesas Electronics Corporation. It features a collector-emitter voltage rating of 100 V and a maximum continuous collector current of 800 mA at both 25 °C and 100 °C operating temperatures. The device operates with a transition frequency of 45 MHz and supports a power dissipation of 1 W in a TO-126 through-hole package. Typical output capacitance is 15 pF. The component is lead-free compliant but not lead-compliant under specific regulatory definitions, with a minimum order quantity of 200 units.
Feature Summary
- Designed for audio amplifier driver applications
- Suitable for small mount spaces due to compact package
- High voltage capability for discrete semiconductor use
Applications
- Audio amplifier drivers
- Discrete semiconductor circuits
- Small signal switching applications
Procurement Notes
Verify the specific ordering suffix AZ against the official Renesas datasheet to confirm package type and compliance status. Confirm availability as the base part number may be discontinued or restricted to existing customers. Check distributor stock levels carefully since inventory counts fluctuate rapidly. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component when a high-voltage NPN transistor with moderate current handling is required for audio driver stages. Consider the TO-126 package constraints for thermal management and board space. Evaluate the 45 MHz frequency response against circuit requirements. Verify that the 1 W power dissipation limit aligns with the expected load conditions in the design.
Part Context
The 2SD415 series belongs to Renesas' lineup of bipolar power transistors intended for audio amplification. The -AZ suffix typically denotes specific packaging or compliance variations within the product family. This component serves as a discrete solution for medium-power applications where high voltage tolerance is necessary.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult official Renesas documentation for cross-reference data.
