DTA143TE3TL

Overview

The DTA143TE3TL is a PNP digital transistor from the ROHM DTA143T series, housed in an EMT3 (SOT-416) surface-mount package. It integrates a single bias resistor with a nominal value of 4.7 kΩ. The device supports a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. Key electrical parameters include a DC current gain (hFE) ranging from 100 to 600 at -1 mA and -5 V, and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW, with an operating junction temperature up to +150°C.

Feature Summary

• Built-in biasing resistors enable inverter circuit configuration without external input components.
• Thin-film resistors provide complete isolation to allow positive input biasing and minimize parasitic effects.
• Operation requires only on/off condition settings, simplifying circuit design.

Applications

• Inverter circuits
• Interface logic
• Driver stages

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 authorized distributors or the manufacturer before placing orders.

Selection Notes

Select this component for applications requiring a compact PNP digital switch with integrated biasing. Ensure the required hFE range and saturation voltage meet the load requirements. Verify that the SOT-416 footprint fits the PCB layout constraints.

Part Context

This part belongs to the DTA143T series of pre-biased transistors. It serves as the PNP counterpart to the DTC143T NPN series. The 'E3' suffix typically denotes the EMT3 (SOT-416) package variant within the broader family.

Replacement Considerations

Check for direct cross-references from other manufacturers offering identical pinouts and electrical characteristics. Verify if alternative packages like SOT-723 or SOT-323 are suitable for space-constrained designs.

FAQ

What is the function of the built-in resistor?

The built-in 4.7 kΩ resistor acts as a base bias resistor, allowing the transistor to function as an inverter without needing an external input resistor.

What is the maximum power dissipation?

The maximum power dissipation is 150 mW when mounted on a reference land at an ambient temperature of 25°C.

Is this component suitable for automotive use?

Standard versions are designed for ordinary electronic equipment. Automotive-grade variants (e.g., DTA143TE3HZG) exist separately and require specific consultation with the manufacturer.
