MUN5135DW1T1G

Overview

The MUN5135DW1T1G is a dual PNP digital transistor manufactured by onsemi, housed in an SC-88 (SOT-363) surface-mount package. It integrates two PNP transistors with built-in bias resistors to simplify circuit design and reduce component count. The device features a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of -100 mA. Typical input resistance is 47 kOhms with a resistor ratio of 0.1. The unit supports a power dissipation of 250 mW and operates within a temperature range of -55°C to +150°C. It complies with RoHS standards and is qualified under AEC-Q101 for automotive applications.

Feature Summary

Procurement Notes

Verify the complete part number including the suffix DW1T1G to ensure correct packaging and tape-and-reel specifications. Confirm AEC-Q101 qualification requirements if deploying in automotive-grade assemblies. Check for lead-free compliance documentation corresponding to specific manufacturing lots. Ensure storage conditions adhere to moisture sensitivity level ratings prior to soldering processes.

Selection Notes

Select this component when a compact dual PNP solution with integrated biasing is required for space-constrained designs. Compare typical input resistance values against microcontroller output drive capabilities to ensure adequate base current. Evaluate thermal performance based on the 250 mW power dissipation limit in the intended enclosure environment. Consider the SC-88 footprint compatibility during PCB layout phase.

Part Context

This component belongs to the MUN513x series of digital transistors from onsemi, which are widely used for replacing multiple discrete components. The MUN5135 variant specifically provides PNP configuration with defined resistor ratios. It complements other series members like MUN5133 or MUN5136 by offering distinct biasing characteristics suitable for different logic interface needs.

Replacement Considerations

Direct substitutes include MUN5133DW1T1G and MUN5136DW1T1G from the same manufacturer family. Verify pinout compatibility and electrical parameter tolerances before substitution. Alternative packages may require schematic redesign due to differing pin configurations.
