DTA114ECAT116

Overview

The DTA114ECAT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors with typical values of 10 kOhms for both the base (R1) and emitter (R2). The device supports a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. Key electrical characteristics include a maximum power dissipation of 200 mW, a transition frequency of 250 MHz, and a minimum DC current gain (hFE) of 100 at -1 mA and -5 V. The component operates within a temperature range up to +150 C.

Feature Summary

• Integrates internal bias resistors to eliminate external resistor requirements for inverter circuit construction.
• Provides high-speed switching capabilities suitable for applications requiring frequencies up to 250 MHz.
• Offers compact surface-mount packaging to facilitate automated assembly and space-constrained designs.

Applications

• General-purpose inverter circuits
• Driver circuits for relays and solenoids
• Logic level translation interfaces

Procurement Notes

Verify the specific suffix CAT116 against the official datasheet to confirm the tape-and-reel quantity and packaging format. Ensure the order matches the required polarity and resistance values. Check for RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement.

Selection Notes

Select this component when a PNP configuration with 10 kOhm bias resistors is required. Compare the -50 V breakdown voltage and -100 mA current rating against circuit demands. Consider the SOT-23-3 footprint constraints and thermal dissipation limits relative to the application environment.
