2SD1815S-TL-H

Single Bipolar Transistors Overview

The onsemi 2SD1815S-TL-H is an NPN silicon epitaxial planar bipolar junction transistor designed for high-current switching applications. It features a TP-FA surface-mount package (SC-63/TO-252) with a maximum collector current of 3 A and a collector-emitter voltage rating of 100 V. The device exhibits low collector-to-emitter saturation voltage, excellent hFE linearity, and a transition frequency of 180 MHz. Electrical characteristics include a DC current gain ranging from 40 to 400 depending on the rank, a collector cutoff current of 1 µA, and a power dissipation capability of 1 W at 25°C ambient temperature.

Single Bipolar Transistors Feature Summary

• Low collector-to-emitter saturation voltage for efficient switching
• Excellent linearity of DC current gain across operating ranges
• High transition frequency supporting fast switching times
• Halogen-free compliance for environmental safety

Single Bipolar Transistors Applications

• Relay drivers
• High-speed inverters
• Converters
• General high-current switching applications

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TL' confirms the TP-FA reel packaging format rather than bulk bag shipping. Confirm RoHS and halogen-free status matches project requirements. Check for any recent Product Change Notices or End-of-Life announcements directly from onsemi documentation before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when a single NPN transistor with 100V breakdown and 3A continuous current capacity is required in a TO-252 footprint. Ensure the application demands low saturation voltage and high-frequency performance. Verify that the thermal management strategy supports the specified 1W dissipation limit at the intended case temperature.

Single Bipolar Transistors Part Context

This part belongs to the 2SD1815 family of bipolar transistors manufactured by onsemi. It serves as the NPN counterpart to the 2SB1215 PNP device within the same datasheet specification. The family is characterized by its small-sized package design, which allows for compact and slim printed circuit board layouts in modern electronic equipment.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same series include the 2SD1815T-TL-H (different package) and 2SD1815S-TL-E (non-halogen). Cross-manufacturer replacements require matching the 100V VCEO, 3A IC, TO-252 package, and electrical parameters such as hFE and fT.
