Overview
The DTA115GU3T106 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. The device features a typical input resistance (R1) of 100 kOhms and an emitter-base resistance (R2) of 100 kOhms. Minimum DC current gain (hFE) is specified as 82 at -5 mA and -5 V. Power dissipation is rated at 200 mW, with a maximum operating temperature of +150°C.
Feature Summary
- Integrates built-in bias resistors to eliminate external resistor requirements for basic switching applications.
- Designed for high-speed digital switching with a transition frequency up to 250 MHz.
- Utilizes a compact SOT-323 surface-mount package suitable for space-constrained PCB layouts.
Applications
- General-purpose digital switching circuits
- Interface circuits between logic gates and loads
- Driver stages for small-signal relays or LEDs
Procurement Notes
Verify the specific ordering suffix T106 to confirm the tape-and-reel packaging quantity of 3000 units. Ensure compatibility with standard SMT reflow profiles. Check for RoHS compliance status in the latest manufacturer datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a PNP configuration with high input impedance is required. The 100 kOhm internal resistors suit low-drive current applications. Compare against DTA114 series if lower input resistance is needed for higher drive capability.
Part Context
This part belongs to the DTA115 series of pre-biased transistors from ROHM. It serves as the PNP counterpart to NPN variants like the DTC115 series. The UMT3 package code corresponds to the industry-standard SOT-323 footprint, ensuring broad availability across multiple distributors.
Replacement Considerations
DTA115EU3T106 is confirmed as a direct replacement with identical pinout and package. Verify that alternative substitutes maintain the same -50 V rating and 100 kOhm resistor values to ensure circuit compatibility.
