Product Description

onsemi MMUN2234LT1G is a digital transistor optimized for surface mount assembly in a compact SOT-23 package, offering a maximum collector emitter voltage of 50 V and a minimum DC current gain (hFE) of 80.

This device integrates two bias resistors monolithically with the transistor to eliminate the need for external resistors, greatly simplifying circuit design and reducing board space and component count.

The transistor is designed for low power dissipation up to 400 mW, making it suitable for efficient switching and amplification in industrial and automotive electronics. Its compact dimensions (3.04 mm length, 2.64 mm width, and 1.1 mm height) allow for high density circuit layouts with reliable surface mount soldering.

Qualified to the stringent AEC-Q101 automotive standard, the MMUN2234LT1G can operate reliably over a temperature range up to 150°C, suitable for harsh environments and demanding automotive applications.

Integration of transistor and bias resistors simplifies electronic circuit design. Small SOT-23 package minimizes PCB footprint. Robust thermal and electrical performance for automotive usage. Low power dissipation supports energy efficient applications.

Environmentally friendly Pb-free and halogen-free composition.

This digital transistor is ideal for applications in automotive systems, industrial controls, and electronic switching circuits that require compact, efficient NPN devices with integrated biasing.
