MUN2137T1

Overview

The MUN2137T1 is a PNP Bias Resistor Transistor (BRT) from the MUN2111T1 series, manufactured by onsemi. It integrates a single PNP silicon transistor with a monolithic bias network consisting of a base resistor (R1) and a base-emitter resistor (R2). The device features a collector-emitter voltage (VCEO) of 50 Vdc and a continuous collector current (IC) of 100 mAdc. Internal resistors are specified as R1 = 47 kΩ and R2 = 22 kΩ. It operates within a junction temperature range of -55°C to +150°C and is housed in an SC-59 surface-mount package.

Feature Summary

Integrates a PNP transistor with a monolithic bias network comprising two resistors to replace discrete components.
Designed for low-power surface mount applications using the SC-59 package.
Eliminates external biasing components to reduce system cost and board space.

Applications

Simplifying circuit design by reducing component count
Replacing single devices and external resistor bias networks
Low power surface mount applications

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm availability and specifications. Ensure that the ordering suffix matches the required shipping configuration, such as tape and reel quantities. Cross-reference datasheet details for thermal characteristics and maximum ratings prior to integration into final designs.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for surface mount designs. The SC-59 package is suitable for low power applications. Verify that the internal resistor values of 47 kΩ and 22 kΩ align with the specific circuit requirements for base drive and leakage characteristics.

Part Context

The MUN2137T1 belongs to the MUN2111T1 Series of Preferred Devices from onsemi. This series includes various PNP BRT configurations with different internal resistor combinations. All devices in this series share the same SC-59 package and fundamental electrical ratings, differing primarily in their internal resistance ratios.
