Overview
The DTA143EE3TL is a PNP digital transistor from the ROHM DTA143E series, housed in an SOT-416 (EMT3) surface-mount package. It integrates biasing resistors with R1 and R2 both at 4.7 kΩ. The device supports a maximum collector current of -100 mA and a supply voltage of -50 V. Key electrical parameters include a DC current gain (GI) minimum of 30 at -10 mA output, a transition frequency (fT) of 250 MHz, and a power dissipation rating of 150 mW. The operating junction temperature range extends up to +150 °C.
Feature Summary
- Built-in biasing resistors enable inverter circuit configuration without external input components.
- Simplified circuit design by requiring only on/off condition settings for operation.
- Thin-film resistor construction minimizes parasitic effects.
Applications
- Inverter circuits
- Interface logic
- Driver applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact package type and taping specifications. Confirm RoHS compliance status and long-term availability plans directly with the supplier before finalizing procurement orders.
Selection Notes
Select this component when a PNP digital transistor with equal internal biasing resistors is required. Ensure the application voltage does not exceed the -50 V limit and that the thermal environment allows for proper heat dissipation within the 150 mW power rating.
Part Context
This part belongs to the DTA143E series of Bias Resistor Built-in Transistors (BRBTs). The series includes complementary NPN types (DTC143E) and various packaging options such as SOT-723 and SOT-323. The EE3 variant specifically denotes the SOT-416 package form factor.
Replacement Considerations
Complementary NPN equivalent: DTC143E series. Other package variants in the same family include DTA143EM (SOT-723) and DTA143EUB (SOT-323FL). Verify pinout compatibility and thermal characteristics when substituting.
