MUN5230DW1T1G

Overview

The MUN5230DW1T1G is a dual NPN digital transistor manufactured by onsemi, housed in a SOT-363-6 surface-mount package. It integrates two independent NPN transistors with built-in bias resistors to simplify circuit design and reduce component count. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 1 kOhm with a resistor ratio of 1. Power dissipation is rated at 187 mW, and it operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistors for simplified switching applications
• Provides compact surface-mount packaging suitable for high-density PCB layouts
• Offers robust thermal performance with an extended operating temperature range

Applications

• General-purpose switching circuits requiring compact form factors
• Interface driving for logic level translation
• Battery-powered portable devices where space conservation is critical

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to ensure correct configuration. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required in a minimal footprint. Ensure the 1 kOhm input resistance aligns with the driving source capabilities. Verify that the 100 mA collector current rating exceeds the maximum load requirements of the target application circuit.

Part Context

This part belongs to the MUN5230DW1 series of pre-biased transistors from onsemi. These devices are designed to replace discrete resistor-transistor networks, reducing board space and assembly costs. The SOT-363 package is standard for dual transistor applications in consumer electronics and industrial control systems.

Replacement Considerations

Check for direct pin-compatible alternatives such as other MUN5230 variants or equivalent dual NPN digital transistors from different manufacturers. Ensure replacement parts match the 50 V voltage rating and 100 mA current capacity. Verify that the bias resistor values and ratios remain compatible with the existing circuit design.
