Overview
The DTA015TMT2L is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in resistors for simplified circuit design. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes an internal base resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 47 kOhms, resulting in a typical resistance ratio of 4.7. Packaged in the compact SOT-323FL (SC-85) surface-mount format, it supports a maximum power dissipation of 200 mW and functions within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates PNP bipolar junction transistor with dual biasing resistors to reduce external component count.
- Optimized for high-speed switching applications with a transition frequency of 250 MHz.
- Designed for low-power consumption and efficient thermal management in compact surface-mount layouts.
Applications
- General-purpose signal switching and level shifting in consumer electronics.
- Driver circuits for small-signal loads in portable devices.
- Logic interface buffering between microcontrollers and peripheral components.
Procurement Notes
Verify the specific suffix 'TMT2L' against official ROHM documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with standard SOT-323 footprint designs. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before integration into regulated products.
Selection Notes
Select this component when a PNP configuration with integrated biasing is required for space-constrained designs. The 10 kOhm input resistance suits moderate drive currents, while the 47 kOhm emitter-base resistor ensures reliable turn-off. Compare power dissipation ratings against thermal constraints in the final assembly environment.
Part Context
This part belongs to the DTA015 series of digital transistors from ROHM Semiconductor. The series offers various resistor combinations and packages to accommodate different switching speeds and current requirements. The DTA015TMT2L specifically utilizes the SOT-323FL package for miniaturization.
Replacement Considerations
Check for direct substitutes such as DTA015EMT2L or DTC015 variants if NPN polarity is acceptable. Verify pinout compatibility and electrical parameter equivalence before replacing in existing designs.
