MDC3237T1

Overview

The MDC3237T1 is a bipolar transistor array manufactured by onsemi, housed in a surface-mount SOT-363 package. It integrates two NPN transistors designed for high-frequency applications with a transition frequency of 100MHz. The device supports a maximum collector current of 200mA and withstands a collector-emitter breakdown voltage of 15V. With a power dissipation rating of 150mW, it is suitable for compact circuit designs requiring multiple switching elements.

Feature Summary

• Integrates dual NPN transistors within a single compact surface-mount package
• Capable of high-frequency operation with a 100MHz transition frequency
• Designed for low-power applications with a 150mW maximum power dissipation

Applications

• High-speed digital switching circuits
• Logic gate implementations
• Signal buffering and inversion

Procurement Notes

Verify the specific datasheet for thermal resistance values and absolute maximum ratings before integration. Confirm that the SOT-363 footprint matches the PCB layout requirements. Ensure operating conditions remain within the specified 15V breakdown and 200mA current limits to maintain reliability.

Selection Notes

Select this component when space constraints require multiple discrete transistors in a single package. It is appropriate for designs needing fast switching speeds up to 100MHz. Consider the 150mW power limit for thermal management in dense layouts compared to higher-power alternatives.

Part Context

This part belongs to onsemi's lineup of bipolar transistor arrays. It serves as a compact alternative to using separate discrete NPN transistors, simplifying assembly and reducing board space. The SOT-363 form factor is common in portable electronics and dense consumer devices.

Replacement Considerations

Check for direct pin-compatible replacements from other manufacturers offering similar NPN arrays in SOT-363 packages. Verify that substitute parts meet the 100MHz frequency and 15V voltage specifications.
