Overview
The DTC115ECAHZGT116 is a single NPN digital transistor from the ROHM DTx series, housed in an SOT-23-3 (SST3) surface-mount package. It integrates bias resistors with typical values of 100 kOhms for both R1 and R2, maintaining a 1:1 ratio. Key electrical parameters include a maximum collector-emitter voltage of 30V, continuous collector current of 100 mA, and power dissipation of 350 mW. The device features a minimum DC current gain (hFE) of 82 at 5 mA/5 V, a transition frequency of 250 MHz, and an emitter-base voltage of 3 V. It operates up to +150°C and holds AEC-Q101 automotive qualification.
Feature Summary
- Integrates dual biasing resistors to simplify circuit design by eliminating external input components.
- Automotive-grade reliability certified under AEC-Q101 standards for harsh environment operation.
- Optimized for high-speed switching applications with a 250 MHz transition frequency.
Applications
- Inverter circuits
- Interface drivers
- Automotive electronic control units
Procurement Notes
Verify component authenticity through authorized distribution channels or direct manufacturer confirmation. Ensure the ordering suffix matches the required tape-and-reel packaging configuration. Confirm RoHS compliance status and specific automotive grade requirements against the official datasheet before finalizing procurement orders.
Selection Notes
Select this component when a single NPN switch with integrated 100 kOhm biasing is required. Verify that the 100 mA current rating and 30V voltage limit suit the load conditions. Consider the SOT-23-3 footprint constraints and thermal dissipation capabilities relative to the application's power budget.
Part Context
This part belongs to the ROHM DTx family of digital transistors, which combine bipolar junction transistors with built-in bias resistors. The ECAHZG suffix indicates specific automotive-grade manufacturing processes and packaging variants within the broader DTC115 product line designed for high-reliability environments.
Replacement Considerations
Direct substitutes include DTC115ECA and DTC115ECAT116. Verify pinout compatibility and electrical parameter equivalence before substitution. Alternative packages such as SOT-416 require schematic redesign due to physical footprint differences.
