2SD1815T-TL-H

Single Bipolar Transistors Overview

The 2SD1815T-TL-H is an NPN silicon epitaxial planar transistor from ON Semiconductor, rated for a collector-to-emitter voltage of 100V and a continuous collector current of 3A. It utilizes the TP-FA package (JEITA/JEDEC SC-63, TO-252) with a tape-and-reel shipping format containing 700 units per reel. Key electrical characteristics include a DC current gain (hFE) ranging from 40 to 400 depending on the rank, a transition frequency (fT) of 180 MHz, and a collector-to-emitter saturation voltage as low as 150 mV at 1.5A. The device supports a junction temperature up to 150°C and features fast switching times with a turn-on time of 100 ns.

Single Bipolar Transistors Feature Summary

• Low collector-to-emitter saturation voltage for efficient power handling
• Excellent linearity of hFE across operating ranges
• High fT and fast switching time suitable for high-speed applications
• Halogen-free compliance

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 (TO-252) surface-mount package and tape-and-reel quantity of 700 pieces. Confirm the 'H' suffix indicates halogen-free material composition. Ensure the required hFE rank (S or T) matches the design specifications, as gain varies significantly between ranks. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.

Single Bipolar Transistors Selection Notes

Select this component when a 100V NPN transistor with 3A continuous current capability is required in a compact TO-252 package. Consider the hFE rank requirements; Rank S offers 140-280 gain while Rank T provides 200-400 gain at 0.5A. Evaluate thermal management needs, as the device dissipates 1W at ambient temperature but up to 20W at case temperature. Verify that the switching speed and capacitance parameters meet the specific circuit timing constraints.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1215/2SD1815 family of bipolar transistors designed for high-current switching. The 2SD1815 is the NPN counterpart to the PNP 2SB1215. Both devices share similar electrical characteristics and are intended for use in relay drivers and converters. The family emphasizes small package size to allow for slim and compact equipment designs.
