Overview
The MUN2230T1G is a discontinued NPN Bias Resistor Transistor (BRT) from onsemi, packaged in SC-59. It integrates a single transistor with a monolithic bias network consisting of two resistors: a series base resistor (R1) and a base-emitter resistor (R2). Both resistors have a nominal value of 1 kΩ, resulting in a typical R1/R2 ratio of 1.0. The device supports a maximum continuous collector current of 100 mA and a collector-emitter voltage of 50 Vdc. It operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Integrates a single NPN transistor with a monolithic bias resistor network to replace discrete components.
- Features built-in series base and base-emitter resistors for simplified circuit design.
- Designed to reduce board space and component count in switching applications.
Applications
- General-purpose switching circuits
- Driver circuits for logic interfaces
- Replacement for discrete transistor and resistor networks
Procurement Notes
Verify the active status of this part number before inclusion in new designs, as it is listed as discontinued in official documentation. Confirm availability through authorized distributors or secondary markets if required for existing production maintenance. Ensure compliance with RoHS standards and lead-free packaging specifications during procurement verification.
Selection Notes
Select this component when a compact NPN switching solution with integrated biasing is required. The 1 kΩ internal resistors suit applications needing moderate drive currents. Consider alternative BRTs with different resistance values if specific input impedance characteristics are necessary for the target application interface.
Part Context
This component belongs to the DTC113E/D digital transistor family published by onsemi. It shares electrical characteristics and pin configurations with related parts such as SMUN2230T1G and MUN5230T1G, differing primarily in package type. The datasheet covers multiple variants including SOT-23 and SC-70 packages within the same publication.
Replacement Considerations
SMUN2230T1G serves as an automotive-grade equivalent within the same family. MUN5230T1G offers identical electrical performance in an SC-70/SOT-323 package. Designers should verify pin compatibility and thermal dissipation requirements when substituting these alternatives.
