MUN5113T1G

Overview

The MUN5113T1G is a single PNP digital transistor from the onsemi MUN5113 series, housed in an SOT-323-3 surface-mount package. It integrates a bias resistor network to replace discrete components. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 47 kOhms with a resistor ratio of 1. It operates within a temperature range of -55°C to +150°C and carries AEC-Q100 qualification for automotive applications.

Feature Summary

• Integrates a dual-resistor bias network with a single PNP transistor to simplify circuit design.
• Eliminates the need for external discrete biasing resistors, reducing component count and board space.
• Provides consistent DC current gain characteristics due to integrated resistor matching.

Applications

• Switching applications in automotive electronic control units.
• General-purpose logic level translation circuits.
• Driver stages for low-power loads in consumer electronics.

Procurement Notes

Verify the specific suffix T1G against the manufacturer's latest datasheet to confirm packaging and tape-and-reel specifications. Ensure the sourcing channel provides valid traceability documentation for AEC-Q100 qualified parts intended for automotive use. Cross-reference the full part number with official distributor catalogs to confirm current production status and availability constraints.

Selection Notes

Select this component when a single PNP switch with built-in biasing is required in a compact SOT-323 footprint. Compare the 47 kOhm input resistance against circuit drive requirements to ensure adequate base current. Verify that the 50 V voltage rating exceeds the maximum operating voltage in the target application environment.

Part Context

This part belongs to the MUN5113 family of digital transistors manufactured by onsemi. These devices are designed as drop-in replacements for discrete resistor-transistor networks. The family offers various configurations and resistance values to suit different switching speeds and drive currents while maintaining a small form factor suitable for dense PCB layouts.

Replacement Considerations

Direct substitutes may include other single PNP digital transistors in SOT-323 packages with similar 50V ratings and 47kOhm input resistance, such as those from NXP or Rohm. Verify pinout compatibility and thermal dissipation characteristics before substitution.
