MMBTRA102SS

Overview

The MMBTRA102SS is a single PNP digital transistor manufactured by Diotec Semiconductor, housed in an SOT-23 (TO-236) surface-mount 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, with a total power dissipation of 200 mW. The device features typical base and emitter resistors (R1 and R2) of 10 kOhms each, resulting in a resistance ratio of approximately 1. It operates within a junction temperature range of -55°C to +150°C and offers a transition frequency of 200 MHz.

Feature Summary

• Integrates bias resistor combinations for cost and space savings
• Compliant with RoHS, REACH, and Conflict Minerals regulations

Applications

• Digital controls
• Switching applications
• Signal processing

Procurement Notes

Verify the specific suffix requirements when ordering. The standard version is designated as MMBTRA102SS. Automotive-grade variants exist with suffixes -Q or -AQ, indicating AEC-Q101 compliance or qualification status respectively. Confirm that the required reliability grade matches the application environment before finalizing procurement specifications.

Selection Notes

Select this component for PNP switching tasks requiring integrated biasing in compact designs. Ensure the input voltage limits align with the control logic levels, as the input voltage range varies by model variant. Consider the thermal constraints given the 200 mW power dissipation rating and verify compatibility with standard SMD reflow soldering profiles.

Part Context

This part belongs to the MMBTRA101SS through MMBTRA106SS series of SMD Digital PNP Transistors from Diotec Semiconductor. The series shares common mechanical and environmental characteristics but differs in internal resistor values and input voltage tolerances. The MMBTRA102SS specifically utilizes 10 kOhm resistors for both base and emitter connections.

Replacement Considerations

Direct substitutes may include other PNP digital transistors in SOT-23 packages with similar -50V ratings and 100mA current capabilities. Verify equivalent resistor ratios and DC current gain specifications to ensure functional parity in existing circuits.
