DTC015TEBTL

Overview

The DTC015TEBTL is a single NPN pre-biased digital transistor manufactured by ROHM Semiconductor. It integrates a base resistor (R1) of 100 kOhms within an EMT3F (SOT-416FL) surface-mount package. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (Ic) of 100 mA. Key electrical characteristics include a DC current gain (hFE) of at least 100 at 5 mA and 10 V, a saturation voltage of 150 mV at 250 µA base and 5 mA collector current, and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW, with a maximum operating temperature of +150°C.

Feature Summary

• Integrates a 100 kOhm base resistor to simplify circuit design and reduce component count.
• Provides high-speed switching capabilities with a 250 MHz transition frequency.
• Features low saturation voltage for efficient power management in digital logic applications.

Applications

• General-purpose digital switching circuits
• Interface between microcontrollers and peripheral devices
• Level shifting and buffer stages in embedded systems

Procurement Notes

Verify the specific suffix 'EBTL' corresponds to the EMT3F tape-and-reel packaging configuration. Confirm RoHS compliance status against the latest manufacturer datasheet revision. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is required. Cross-reference the part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a single NPN digital transistor with a 100 kOhm base resistor is required. Compare hFE minimum values and saturation voltages against alternative models like DTC015EUBTL if different packaging or resistance ratios are needed. Verify that the 50 V VCEO rating meets the system's voltage requirements. Consider thermal dissipation limits in high-density PCB layouts.

Part Context

This part belongs to the DTC015 series of bias resistor built-in transistors from ROHM. It shares functional similarities with other variants in the family but differs in packaging and internal resistor configurations. The EMT3F package offers a compact footprint suitable for space-constrained portable electronics and modern consumer devices requiring small form factors.

Replacement Considerations

DTC015EUBTL is a potential substitute offering similar electrical characteristics but housed in an SOT-323FL package. Verify pinout compatibility and physical dimensions before substitution. Other DTC015 series variants may require different base resistances or offer different voltage ratings.
