DTA144EE3TL

Overview

The DTA144EE3TL is a PNP digital transistor from the ROHM DTA144E series, housed in an SOT-416 (EMT3) surface-mount package. It integrates biasing resistors with R1 and R2 both at 47kΩ. Key electrical ratings include a supply voltage of -50V, a maximum collector current of -100mA, and a power dissipation of 150mW. The device features a minimum DC current gain (GI) of 68 and a transition frequency of 250MHz. It operates within a junction temperature range up to 150°C and is supplied in tape-and-reel packaging.

Feature Summary

• Built-in biasing resistors enable inverter circuit configuration without external input resistors
• Simplified circuit design by requiring only on/off condition settings for operation
• Complementary NPN types available in the DTC144E series

Applications

• Inverter circuits
• Interface applications
• Driver circuits

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 finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with equal internal bias resistors is required. Ensure the application voltage does not exceed the -50V supply rating and that the thermal environment allows for proper heat dissipation within the 150mW power limit. Verify compatibility with the SOT-416 footprint during PCB layout.
