DTA113ZCAT116

Overview

The DTA113ZCAT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates biasing resistors with typical values of R1 at 1 kOhm and R2 at 10 kOhm, maintaining a ratio of 10. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of -50 V, a continuous collector current (Ic) of -100 mA, and a minimum DC current gain (hFE) of 33 at -5 mA and -5 V. The device supports a maximum operating frequency of 250 MHz, has a power dissipation rating of 150 mW, and operates within a temperature range up to +150°C.

Feature Summary

• Integrates built-in biasing resistors (R1=1kΩ, R2=10kΩ) to simplify circuit design by eliminating the need for external input resistors.
• Configured as a pre-biased NPN/PNP transistor capable of forming inverter circuits directly from logic signals.
• Complies with AEC-Q101 automotive qualification standards for enhanced reliability in demanding environments.

Applications

• Inverter circuits for signal level shifting
• Driver circuits for low-power loads
• Interface applications between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix CAHZGT116 or T116 against the requested part number to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and AEC-Q101 automotive grade requirements if applicable to the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP solution with integrated base resistance is required for space-constrained designs. Ensure the -50V voltage rating and -100mA current capacity meet the load requirements. Consider the 250MHz frequency limit for high-speed switching applications compared to slower general-purpose transistors.
