DTDG23YPT100

Overview

The DTDG23YPT100 is an NPN digital transistor with built-in resistors and a Zener diode, manufactured by Rohm Semiconductor. It features a collector-emitter voltage (VCEO) of 60 V and a maximum collector current (IC) of 1 A. The device includes an input resistor (R1) of 2.2 kΩ and an emitter-base resistor (R2) of 22 kΩ. It operates within a temperature range of -55°C to +150°C, with a power dissipation rating of 1.5 W. The component utilizes the MPT3 surface-mount package, equivalent to TO-243AA, measuring 4.0x4.5 mm with a thickness of 1.7 mm. It offers a DC current gain (hFE) of at least 300 at 500 mA.

Feature Summary

• Integrates biasing resistors and a Zener diode to simplify circuit design without external components.
• Provides high DC current gain for efficient switching applications.
• Utilizes a compact surface-mount package suitable for automated assembly.

Applications

• Inverter circuits requiring simplified input configurations.
• Switching applications in consumer electronics.
• Driver stages for low-power logic interfaces.

Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as variants exist for tape-and-reel or cut-tape formats. Confirm RoHS compliance status through official documentation before integration. Check for any automotive qualification requirements if used in vehicle systems, as standard grades may not be suitable. Ensure the supplier provides valid traceability documents matching the manufacturer's part marking specifications.

Selection Notes

Select this component when a pre-biased NPN transistor with integrated protection is required. The 2.2 kΩ input resistor value determines the base drive characteristics; verify compatibility with the driving logic level. Consider the 60 V voltage rating against peak transient voltages in the application. Compare power dissipation limits with thermal management capabilities of the target PCB layout.

Part Context

This part belongs to Rohm’s DTDG series of digital transistors, which combine bipolar junction transistors with internal passive components. The MPT3 package is commonly used for small-signal switching devices requiring moderate current handling. The 'T100' suffix typically denotes the taping specification for reel-based manufacturing processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout compatibility and electrical parameters such as VCEO, IC, and R1/R2 values before considering alternative manufacturers. Consult official replacement guides from Rohm for validated cross-reference data.
