DTB723YMT2L

Overview

The DTB723YMT2L is a PNP digital transistor from the ROHM DTB723Y series, featuring built-in biasing resistors. It operates with a supply voltage of -30V and a maximum collector current of -200mA. The device incorporates thin-film resistors for complete isolation, allowing negative input biasing without parasitic effects. Key electrical parameters include an input resistance (R1) of 2.2kΩ, an emitter-base resistance (R2) of 10kΩ, and a DC current gain (GI) of at least 140. It is housed in a VMT3 (SC-105AA/SOT-723) surface-mount package.

Feature Summary

• Built-in biasing resistors enable inverter circuit configuration without external input resistors.
• Thin-film resistor construction provides complete isolation to allow negative input biasing.
• Eliminates parasitic effects associated with discrete resistor networks.
• Simplifies circuit design by requiring only on/off condition settings.

Applications

• Switching circuits
• Inverter circuits
• Interface circuits
• Driver circuits

Procurement Notes

Verify the specific ordering suffix T2L corresponds to the VMT3 tape-and-reel packaging format containing 8,000 units per reel. Confirm that the component meets RoHS compliance standards as indicated in the datasheet. Ensure the application environment remains within the specified storage temperature range of -55°C to +150°C and does not exceed the absolute maximum ratings for voltage or current.

Selection Notes

Select this PNP variant when a complementary NPN type like the DTD723Y series is required for push-pull configurations. Consider the 2.2kΩ input resistance and 10kΩ emitter-base resistance values for proper biasing network design. Verify that the -30V supply voltage rating aligns with the system's operational requirements and that the SOT-723 package fits the available PCB footprint constraints.

Part Context

This component belongs to the DTB723Y series of digital transistors manufactured by ROHM. It serves as the PNP counterpart to the NPN DTD723Y series. The device integrates a bipolar transistor with two internal resistors to simplify switching applications. It is designed for general electronic equipment and is not intended for automotive or high-reliability radiation-tolerant applications.

Replacement Considerations

The DTD723Y series serves as the complementary NPN alternative within the same product family. No other direct cross-manufacturer substitutes are confirmed in the provided documentation. Verify pinout compatibility if considering generic equivalents, as the standard configuration is Collector, Base, Emitter.
