Overview
The DTC123JETL is an NPN digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of 50 V and a maximum collector current of 100 mA. The device includes a base resistor (R1) of 2.2 kΩ and an emitter-base resistor (R2) of 47 kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 80 at 10 mA and 5 V, a saturation voltage of 300 mV max at specific test conditions, and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW, housed in an EMT3 (SOT-416/SC-75A) surface-mount package.
Feature Summary
- Built-in bias resistors enable inverter circuit configuration without external input resistors
- NPN polarity with pre-biased structure for simplified on/off control
- Compact SOT-416 surface-mount package suitable for space-constrained designs
Applications
- General-purpose switching circuits
- Inverter logic applications
- Driver circuits for low-power loads
Procurement Notes
Verify the ordering part number DTC123JETL against the manufacturer's current datasheet to ensure compatibility with required packaging options such as tape and reel quantities. Confirm RoHS compliance status and check for any specific handling instructions related to the EMT3 package during assembly processes.
Selection Notes
Select this component when an NPN digital transistor with R1=2.2kΩ and R2=47kΩ is required in a SOT-416 package. Ensure the application voltage does not exceed 50 V and current requirements remain within the 100 mA limit. Consider thermal constraints given the 150 mW power dissipation rating for surface-mount operation.
Part Context
This part belongs to the DTC123 series of digital transistors from Rohm Semiconductor. It is a standard-grade product designed for general electronic equipment. It is distinct from automotive-grade variants like the DTC123JE3HZG, which carry AEC-Q101 certification. The device represents a common solution for replacing discrete resistor-transistor combinations in compact PCB layouts.
Replacement Considerations
Direct pin-compatible substitutes include DTC123JE and DTC123JUB, though package differences exist (SOT-416 vs SOT-323FL). Verify internal resistor values and hFE ranges match before substitution. Automotive applications require the DTC123JE3HZG variant instead.
