Overview
The DTA043TUBTL is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. The device includes an internal base resistor (R1) of 4.7kΩ and an emitter-base resistor (R2) of 10kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 100 at 5mA and 10V, and a saturation voltage of 150mV at 500µA base current and 5mA collector current. It has a transition frequency of 250MHz and a power dissipation rating of 200mW.
Feature Summary
- Integrates dual bias resistors to reduce component count and board space
- Optimized for high-speed switching applications with 250MHz transition frequency
- Designed for surface-mount assembly in compact UMT3F packages
Applications
- General-purpose logic interface circuits
- Driver stages for relays and small loads
- Level shifting between different voltage domains
Procurement Notes
Verify the specific suffix 'TUBTL' against official Rohm documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the distributor part number with the manufacturer's latest datasheet to confirm availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when a PNP configuration with integrated biasing is required for space-constrained designs. The 4.7kΩ base resistor suits standard TTL or CMOS logic levels. Consider the 200mW power dissipation limit and thermal management requirements for the UMT3F package during layout planning.
Part Context
This part belongs to Rohm's DTA043 series of pre-biased transistors. It shares the same core transistor structure as variants like DTA043EUBTL but differs in packaging and internal resistor configurations. The UMT3F package provides a compact footprint suitable for modern portable electronics and dense PCB layouts.
Replacement Considerations
DTA043EUBTL offers similar electrical performance but may differ in package dimensions. Verify pinout compatibility and physical footprint before substitution. Other DTA043 variants with different resistor values are not direct replacements.
