Overview
The DTC143ECAHZGT116 is an NPN digital transistor from ROHM Semiconductor, designed for automotive applications. It integrates bias resistors (R1 and R2) of 4.7 kΩ each, eliminating the need for external input components in inverter circuits. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a power dissipation (PD) of 200 mW. The device operates within a junction temperature range of -55°C to +150°C and features a transition frequency of 250 MHz. It complies with AEC-Q101 standards for automotive grade reliability.
Feature Summary
- Built-in biasing resistors simplify circuit design by enabling inverter configuration without external input resistors.
- Automotive-grade reliability compliant with AEC-Q101 standards for high-temperature operation.
- Compact SOT-23 (SST3) surface-mount package suitable for space-constrained designs.
Applications
- Inverter circuits
- Interface circuits
- Driver circuits
Procurement Notes
Verify the complete part number including the suffix T116 to confirm the tape-and-reel packaging quantity of 3000 units. Ensure the specific HZG variant is selected for automotive-grade compliance rather than standard commercial versions. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when an NPN pre-biased transistor with 4.7 kΩ internal resistors is required for automotive signal switching. Compare against complementary PNP types like DTA143ECAHZG for push-pull configurations. Verify that the 50 V breakdown voltage and 100 mA current rating meet the specific load requirements of the target application circuit.
Part Context
This part belongs to the DTx series of digital transistors from ROHM Semiconductor. The 'HZG' suffix typically denotes automotive-grade qualification and specific packaging variants. It is functionally similar to the DTC143ECAHZG but includes the T116 suffix indicating the reel packaging format.
Replacement Considerations
Direct substitutes include other ROHM parts in the same family such as DTC143ECAHZG or DTC143ECAT116, provided the packaging and automotive grade requirements match. External equivalents must be verified for identical resistor values (4.7 kΩ/4.7 kΩ), polarity, and voltage ratings.
