Overview
The MMUN2136LT1G is a single PNP Bias Resistor Transistor (BRT) from onsemi, housed in an SOT-23 package. It integrates a monolithic bias network consisting of a series base resistor and a base-emitter resistor to replace discrete components. The device features a collector-emitter voltage of 50 Vdc and continuous collector current of 100 mAdc. Electrical characteristics include a typical DC current gain of 150 at 5.0 mA and 10 V, with a minimum of 80. The internal resistors are typically 100 kOhms each, yielding a ratio of 1.0. Thermal dissipation is rated at 246 mW at 25°C ambient temperature.
Feature Summary
- Integrates a single transistor with a monolithic bias network containing two resistors to reduce board space and component count.
- Qualified for automotive applications under AEC-Q101 standards and capable of PPAP requirements.
Applications
- Automotive electronic circuits requiring unique site and control change compliance.
- General-purpose switching applications replacing discrete transistor and resistor networks.
- Logic interface circuits utilizing built-in biasing for simplified design.
Procurement Notes
Verify the specific ordering suffix 'LT1G' corresponds to the SOT-23 package configuration and tape-and-reel shipping format. Confirm that the NSV prefix variant is required if automotive qualification and PPAP capability are necessary for the target application environment.
Selection Notes
Select this component when a PNP digital transistor with a 1:1 resistor ratio is needed. Ensure the 50 V collector-emitter rating and 100 mA current capacity meet the circuit requirements. Verify compatibility with the SOT-23 footprint and check thermal derating curves for high-temperature operation scenarios.
Part Context
This part belongs to the MUN2136/DTA115E family of digital transistors. It shares identical electrical specifications with variants such as the MUN2136T1G and DTA115EE but differs in physical packaging. The MMUN2136LT1G specifically utilizes the SOT-23 case style for surface-mount assembly.
Replacement Considerations
Direct functional equivalents include the MUN2136T1G and DTA115EE. Substitution requires verifying pinout compatibility and ensuring the replacement package matches the PCB layout constraints.
