Overview
The MMBTRC120SS is a surface-mount digital NPN transistor manufactured by Diotec Semiconductor, housed in an SOT-23 (TO-236) package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a maximum output voltage of 50 V and a continuous output current of 100 mA. The device supports a power dissipation of 200 mW and operates within a junction temperature range of -55°C to +150°C. For the MMBTRC120SS specifically, the built-in resistor combination consists of R1 = 10 kΩ and R2 = 4.7 kΩ. The DC current gain (GI) has a minimum value of 24 at VO = 5 V and IO = 10 mA.
Feature Summary
- Integrated bias resistor combinations reduce component count and simplify circuit layout.
- Compliant with RoHS directives without exemption and REACH regulations.
- Conflict Minerals compliant manufacturing process.
Applications
- Digital control systems
- Switching circuits
- Signal processing applications
Procurement Notes
Verify the specific ordering suffix when sourcing this component. Standard commercial grade parts do not carry automotive qualifications. Only suffixes explicitly designated as -Q or -AQ indicate AEC-Q101 compliance or qualification respectively. Confirm package type and marking codes match the required specifications for the intended assembly process.
Selection Notes
Select the MMBTRC120SS when a 10 kΩ input resistor and 4.7 kΩ emitter-base resistor are required for NPN digital switching. Ensure the application voltage does not exceed the 50 V collector-emax rating. Consider the 200 mW power dissipation limit and verify thermal management requirements for the SOT-23 package under operating conditions.
Part Context
This component belongs to the MMBTRC116SS through MMBTRC121SS series of SMD digital NPN transistors from Diotec Semiconductor. All members of this family share identical physical dimensions, pin configurations, and general electrical ratings, differing only in their internal resistor values and corresponding marking codes.
Replacement Considerations
Direct substitutes within the same Diotec series include MMBTRC119SS and MMBTRC121SS, provided the different resistor ratios are acceptable for the circuit design. Cross-manufacturer replacements must be verified for matching pinout, voltage ratings, and current capabilities.
