Overview
The onsemi MUN5131T1G is a PNP Bias Resistor Transistor (BRT) featuring a monolithic bias network with two integrated resistors: a series base resistor and a base-emitter resistor. It operates within a collector-emitter voltage range of 50 Vdc and supports continuous collector currents up to 100 mAdc. The device utilizes an SC-70/SOT-323 package, offering a typical input resistance of 2.2 kOhms and a resistor ratio of 1.0. Designed for surface-mount applications, it functions across a junction temperature range of -55°C to +150°C.
Feature Summary
- Integrates a single transistor with a monolithic bias network consisting of a series base resistor and a base-emitter resistor to replace discrete components.
- Reduces system cost and board space by eliminating the need for external individual biasing resistors.
Applications
- Automotive circuits requiring AEC-Q101 qualification and PPAP capability
- General-purpose digital switching applications
- Logic level translation interfaces
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and shipping quantity. Confirm RoHS compliance and Pb-free status requirements for the target assembly process. Ensure the selected distributor provides traceability data consistent with automotive quality standards if applicable.
Selection Notes
Select this component when a compact PNP solution with integrated biasing is required. Verify that the SC-70/SOT-323 footprint matches the PCB layout constraints. Ensure the 50 V collector-emitter rating exceeds the maximum circuit voltage under all operating conditions.
Part Context
This part belongs to the MUN5131 series of digital transistors manufactured by onsemi. It is functionally equivalent to other BRTs in the DTA123E family but packaged specifically in the SC-70/SOT-323 form factor. The 'T1G' suffix indicates tape and reel packaging in a Pb-free configuration.
Replacement Considerations
MUN2131T1G (SC-59 package), MMUN2131LT1G (SOT-23 package), DTA123EET1G (SC-75 package). Verify pinout compatibility and thermal dissipation characteristics before substitution.
