DTD513ZMT2L

Overview

The DTD513ZMT2L is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in a VMT3 (SOT-723) surface-mount package. It integrates bias resistors with a typical input resistance of 1 kOhm and a ratio of 10. Key electrical parameters include a maximum collector-emitter voltage of 12V, continuous collector current of 500mA, and power dissipation of 150mW. The device features a minimum DC current gain (hfe) of 140 at -100mA/-2V, a saturation voltage of 60mV, and an emitter-base voltage of -2.5V. It operates up to 260MHz and supports temperatures up to +150°C.

Feature Summary

• Integrates thin-film bias resistors for simplified circuit design without external components.
• Provides complete isolation between bias resistors to allow negative biasing off the input.
• Eliminates parasitic effects through integrated resistor architecture.

Applications

• Inverter circuits requiring pre-biased switching
• General-purpose digital logic interfaces
• Low-voltage signal switching applications

Procurement Notes

Verify the specific suffix ZMT2L against official datasheets to confirm the VMT3/SOT-723 package and tape-and-reel quantity. Confirm RoHS compliance status directly from the manufacturer's documentation before integration. Ensure the ordering part number matches the required polarity and resistance values for the target application design.

Selection Notes

Select this component for designs requiring a compact NPN digital transistor with 1kOhm input resistance. Verify that the 12V voltage rating and 500mA current capacity meet the load requirements. Consider the complementary PNP type if a full bridge or push-pull configuration is needed. Check thermal constraints given the 150mW power dissipation limit in the small SMD package.

Part Context

This part belongs to the DTD513ZE series of pre-biased transistors. It serves as the surface-mount variant of the DTD513, offering equivalent electrical performance in a smaller footprint suitable for high-density PCB layouts. It is designed to replace discrete resistor-transistor combinations in digital switching roles.

Replacement Considerations

The DTB513ZMT2L is the complementary PNP version within the same series. For direct pin-compatible substitution with opposite polarity, verify the DTB513ZMT2L specifications. Other members of the DTD513ZE family may offer different resistance ratios but require electrical validation.
