Overview
DTA143ECAHZGT116 is a PNP digital transistor from ROHM Semiconductor, featuring built-in bias resistors in an SOT-23 (SST3) surface-mount package. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The internal resistor network consists of R1 = 4.7kΩ and R2 = 4.7kΩ. Key electrical limits include a power dissipation of 0.2W, an emitter-base voltage of -5V, and a DC current gain (hFE) minimum of 100 at -1mA/-5V. It complies with AEC-Q101 automotive standards and supports a storage temperature range of -55°C to +150°C.
Feature Summary
- Built-in biasing resistors (R1=R2=4.7kΩ) simplify circuit design by eliminating external input resistors for inverter configurations.
- Automotive-grade reliability certified under AEC-Q101 standards for high-temperature operation up to 150°C.
- Compact SOT-23 surface-mount package suitable for space-constrained applications.
Applications
- Inverter circuits
- Interface logic drivers
- General-purpose switching applications
Procurement Notes
Verify the complete part number including the T116 tape-and-reel suffix against official ROHM documentation to ensure correct packaging quantity and handling specifications. Confirm RoHS compliance status and check for any specific automotive qualification requirements relevant to the target application environment before finalizing procurement.
Selection Notes
Select this component when a PNP digital transistor with equal 4.7kΩ bias resistors is required for automotive or industrial interfaces. Ensure the -50V VCEO rating meets the system voltage requirements and that the SOT-23 package dimensions fit the PCB layout constraints. Verify thermal management capabilities given the 0.2W power dissipation limit.
Part Context
This device belongs to the DTA series of bias-resistor-built-in transistors (BRTs). It serves as the PNP counterpart to the DTC143ECAHZG NPN digital transistor. Both share identical internal resistor values and package types, allowing for complementary push-pull or differential signaling designs within the same ROHM product family.
Replacement Considerations
The DTA143XCAHZG is listed as a similar specification alternative within the ROHM portfolio. Verify pinout compatibility and exact resistor tolerances before substitution. No other cross-manufacturer equivalents are confirmed in the provided data.
