DTD713ZMT2L

Overview

The DTD713ZMT2L is an NPN digital transistor from the Rohm Semiconductor DTD713Z series, featuring built-in bias resistors. It operates with a maximum collector current of 200mA and a supply voltage of 30V. The device incorporates thin-film resistors for complete isolation, allowing negative input biasing while eliminating parasitic effects. Key electrical characteristics include a typical DC current gain (GI) of 140 at 100mA output, an input resistance (R1) of 1kΩ, and an emitter-base resistance (R2) of 10kΩ. It is housed in a VMT3 package with a power dissipation rating of 150mW.

Feature Summary

• Built-in bias resistors enable inverter circuit configuration without external input resistors.
• Thin-film resistor construction provides complete isolation to allow negative input biasing.
• Elimination of parasitic effects through isolated internal resistor design.
• Simplified 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 against official documentation to confirm the exact package type and taping specifications. Confirm RoHS compliance status and lead-free manufacturing details directly with the manufacturer or authorized distributors before procurement. Ensure the component meets general-use electronic equipment requirements as specified in the datasheet.

Selection Notes

Select this component for applications requiring compact NPN switching with integrated biasing. Verify that the 200mA collector current and 30V supply voltage ratings align with the target circuit demands. Consider the complementary DTB713Z series if PNP polarity is required. Ensure thermal management accommodates the 150mW power dissipation limit under operating conditions.

Part Context

This part belongs to the DTD713Z series of NPN digital transistors manufactured by Rohm Semiconductor. It is designed as a standard-grade component for general-purpose electronic equipment. The series includes complementary PNP types and is intended for use in devices such as audio-visual equipment, office automation, and communication devices.

Replacement Considerations

The complementary PNP type in the same series is the DTB713Z. Verify pinout compatibility and electrical parameter alignment when substituting with other NPN digital transistors from different manufacturers.

FAQ
