Overview
The SMUN5111T1 is a single PNP Bias Resistor Transistor (BRT) manufactured by onsemi. It integrates a single NPN transistor with a monolithic bias network consisting of two resistors: a series base resistor and a base-emitter resistor, packaged in the SOT-323 form factor. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a typical input resistance of 10 kOhms. The device operates within a temperature range of -55°C to +150°C and features a minimum DC current gain (hFE) of 80 at 5 mA and 10 V.
Feature Summary
- Integrates a single transistor with a monolithic bias network to replace discrete components
- Designed for low power surface mount applications where board space is limited
- Simplifies circuit design by eliminating external resistor bias networks
Applications
- Low power surface mount applications requiring compact footprint
- Circuit designs needing simplified biasing without external resistors
- High density PC boards where space is at a premium
Procurement Notes
Verify the specific suffix 'T1' against official onsemi documentation to confirm package type and availability status. Ensure compatibility with SOT-323 requirements. Check for RoHS compliance details in the latest datasheet. Confirm lead times and packaging options directly with authorized distributors or the manufacturer.
Selection Notes
Select this component when a single PNP digital transistor with integrated biasing is required in an SOT-323 package. Consider the 50 V voltage rating and 100 mA current capability for suitability. Evaluate the 10 kOhm input resistance against circuit requirements. Compare with other MUN51xx series variants if different configurations are needed.
Part Context
The SMUN5111T1 belongs to the MUN5111 series of Bias Resistor Transistors from onsemi. This series is designed to simplify circuit design by integrating bias resistors with transistors. The T1 suffix typically denotes the SOT-323 package variant. It is part of a broader family of digital transistors offering various configurations and packages.
Replacement Considerations
Direct replacements may include other MUN5111 series variants with compatible packages. Verify pinout and electrical specifications before substitution. Consult onsemi documentation for approved alternatives.
