Overview
The MDC3105LT1 is a discontinued bipolar power driver IC manufactured by onsemi. It provides a digital-to-inductive load interface, functioning as a relay and solenoid driver. The device features a single low-side output with a maximum continuous current of 500mA. It operates within an ambient temperature range of -40°C to +85°C. The component is housed in a surface-mount SOT-23-3 (TO-236) package. It supports a maximum load voltage of 6V and does not require a separate supply voltage for operation.
Feature Summary
- Provides direct interface between digital logic signals and inductive loads such as relays or solenoids
- Integrates protection diodes for safe switching of inductive loads
- Designed for low-side output configuration to drive loads connected to ground
Applications
- Relay driver circuits
- Solenoid actuation systems
- Digital-to-inductive load interface modules
Procurement Notes
This component is officially listed as discontinued by the manufacturer. Availability is limited to existing stock from authorized distributors. Verify RoHS compliance status, as documentation indicates non-compliance. Confirm package integrity and authenticity through certified suppliers before integration into new designs.
Selection Notes
Select this part only for legacy system maintenance or replacement where the specific 500mA low-side bipolar driver characteristics are required. Due to its discontinued status, evaluate alternative modern equivalents that offer similar current handling and package dimensions if designing new hardware. Ensure the target application voltage remains within the 6V maximum limit.
Part Context
The MDC3105LT1 belongs to the MDC3105 series of power drivers produced by onsemi. It is categorized under Power Management (PMIC) and specifically within Distribution Switches and Load Drivers. The product falls under the broader category of Bipolar Junction Transistors (BJT) and discrete semiconductor devices designed for standard industrial applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the part is discontinued, engineers must identify functional equivalents based on pinout compatibility, current rating, and voltage specifications from other manufacturers.
