DTC123YEBHZGTL

Overview

The DTC123YEBHZGTL is a single NPN pre-biased digital transistor manufactured by ROHM Semiconductor. It integrates bias resistors within an EMT3F (SOT-416FL) surface-mount package. Key electrical specifications include a collector-emitter breakdown voltage of 50V and a continuous collector current of 100mA. The device features a typical input resistance of 2.2kΩ and supports a maximum operating frequency of 250MHz. Power dissipation is rated at 150mW, with an operating temperature range extending up to +150°C.

Feature Summary

• Integrates bias resistors directly into the NPN transistor structure for simplified circuit design.
• Utilizes compact SOT-416FL surface-mount packaging for efficient board space utilization.
• Supports high-speed switching applications with a maximum operating frequency of 250MHz.

Applications

• General-purpose signal switching in consumer electronics
• Interface circuits between logic gates and loads
• Driver stages for small-signal relay or LED control

Procurement Notes

Verify component authenticity through authorized distribution channels to ensure compliance with ROHM quality standards. Confirm that the specific suffix matches project requirements, as variations may exist. Check current availability status, as this part may be subject to lifecycle restrictions or obsolescence notices. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet prior to assembly.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for low-power switching tasks. The 50V rating suits general logic-level applications, while the 100mA current capability handles moderate loads. Consider the SOT-416FL footprint constraints during PCB layout. Evaluate thermal management needs given the 150mW power dissipation limit in enclosed environments.

Part Context

This device belongs to ROHM's family of digital transistors, which combine bipolar junction transistors with internal bias networks. These components reduce external component count and simplify schematic design compared to discrete resistor-transistor combinations. The DTC123 series specifically targets cost-sensitive, space-constrained applications requiring reliable switching performance.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters before considering alternative manufacturers. Note that this specific variant may be designated as 'Not For New Designs' in some sources; consult official ROHM channels for current lifecycle status and recommended alternatives.
