Overview
The MMBTRA106SS is a surface-mount digital PNP transistor from Diotec Semiconductor, housed in an SOT-23 package. It features integrated bias resistors with values of R1=4.7 kΩ and R2=47 kΩ. Key electrical ratings include a maximum collector-emitter voltage (VCEO) of -50 V, a continuous collector current (IC) of -100 mA, and a total power dissipation (Ptot) of 200 mW at 25°C ambient temperature. The device operates within a junction temperature range of -55°C to +150°C. Electrical characteristics specify a DC current gain (hFE) of 80, an output cutoff current of 500 nA, and a transition frequency of 200 MHz.
Feature Summary
- Integrates bias resistor combinations to reduce component count and PCB space requirements.
- Compliant with RoHS directives without exemptions, REACH regulations, and conflict mineral standards.
Applications
- Digital control circuits
- Switching applications
- Signal processing
Procurement Notes
Verify the specific suffix when ordering. The base model MMBTRA106SS represents the standard commercial/industrial grade. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes parts undergoing qualification. Confirm the required reliability grade matches the application environment before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring a compact PNP digital switch with predefined internal resistance ratios. The MMBTRA106SS offers a fixed R2/R1 ratio between 0.055 and 0.185. Ensure the input voltage limits (-5 V to +20 V) align with the driving logic levels. Consider thermal constraints if operating near the maximum power dissipation limit of 200 mW.
Part Context
This part belongs to the MMBTRx series of SMD digital PNP transistors manufactured by Diotec Semiconductor. The series includes variants with different internal resistor configurations, ranging from MMBTRA101SS to MMBTRA106SS. All members share the same SOT-23 mechanical footprint and general electrical ratings, differing primarily in their internal bias resistor values and corresponding input voltage thresholds.
Replacement Considerations
Direct substitutes must match the SOT-23 package, PNP polarity, and -50V/-100mA ratings. Verify that alternative components provide compatible internal resistor ratios and input voltage ranges. Check for equivalent thermal performance and ensure any replacement meets the same RoHS and REACH compliance standards.
