Overview
The DTC115GUAT106 is a single NPN digital transistor manufactured by Rohm Semiconductor, designed for surface-mount applications in the UMT3 (SC-70/SOT-323) package. It integrates an internal base resistor (R1) of 47 kOhms to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (Ic) of 100 mA. The device features a DC current gain (hFE) of at least 68 at Ic=5mA and Vce=5V, with a maximum saturation voltage of 300 mV at Ib=500µA and Ic=10mA. It operates within a temperature range of -55°C to +100°C and has a power dissipation rating of 200 mW.
Feature Summary
- Integrated pre-bias configuration reduces external component count
- High-speed switching capability suitable for digital logic interfaces
- Compact surface-mount packaging for space-constrained designs
Applications
- General-purpose switching in digital circuits
- Driver stages for low-power loads
- Logic level translation interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct resistance values and packaging type. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the distributor part number with the official Rohm product code to avoid substitution errors during procurement.
Selection Notes
Select this component when a single NPN digital transistor with a 47 kOhm base resistor is required. Ensure the application voltage does not exceed 50 V and current stays below 100 mA. Consider the UMT3 package dimensions for PCB layout compatibility. Verify thermal management needs given the 200 mW power dissipation limit in enclosed environments.
Part Context
This part belongs to the DTC1xx series of pre-biased transistors from Rohm. The '1' in DTC115 indicates an NPN configuration with only the base resistor (R1) integrated. The '15' typically denotes the specific resistance value combination, here 47 kOhms for R1. It is part of a broader family including PNP variants and dual-transistor options.
Replacement Considerations
Check for direct pin-compatible substitutes from other manufacturers such as Diodes Incorporated or Toshiba. Verify that alternative parts match the 50 V VCEO, 100 mA Ic, and 47 kOhm R1 specifications. Ensure the replacement package matches UMT3/SC-70-3 dimensions and thermal characteristics.
