Overview
The DTD743XMT2L is an NPN digital transistor from the ROHM Semiconductor DTD743X series, featuring built-in biasing resistors. It operates with a maximum supply voltage of 30V and supports a continuous collector current of 200mA. The device incorporates thin-film resistors for complete isolation, allowing negative input biasing without parasitic effects. Key electrical parameters include a typical input resistance (R1) of 4.7kΩ, a resistance ratio (R2/R1) ranging from 1.7 to 2.6, and a DC current gain (GI) of at least 140. Transition frequency reaches 260MHz, with power dissipation rated at 150mW.
Feature Summary
- Built-in biasing resistors enable inverter circuit configuration without external input components.
- Thin-film resistor construction provides complete isolation, eliminating parasitic effects and permitting negative input biasing.
- Simplified operation requires only setting on/off conditions for circuit design.
Applications
- Switching circuits
- Inverter circuits
- Interface circuits
- Driver circuits
Procurement Notes
Verify component authenticity through authorized channels. Confirm RoHS compliance status via official documentation. Ensure storage temperature remains within -55°C to +150°C. Check for physical damage prior to installation. Validate package marking against datasheet specifications.
Selection Notes
Select this component for applications requiring simplified biasing networks. Consider the 30V supply limit and 200mA current capacity. Evaluate thermal management for 150mW dissipation. Compare R1 values against logic drive requirements. Assess transition frequency needs for high-speed switching.
Part Context
This part belongs to the DTD743X series of NPN digital transistors. Complementary PNP types are available in the DTB743X series. The VMT3 package corresponds to the SC-105AA standard. The T2L suffix indicates reel packaging for surface mount assembly.
Replacement Considerations
Direct substitutes require matching NPN polarity, 30V rating, and 200mA current capability. Verify equivalent built-in resistor ratios and transition frequencies. Ensure compatible SMD package dimensions for PCB footprint replacement.
