Overview
The QTM452T1 is a single-channel optoisolator manufactured by QT Brightek, featuring a transistor photovoltaic output. It utilizes a 5-Mini-Flat package with surface mount installation. The device provides an isolation voltage of 3750Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a typical forward voltage of 1.45V, an output current of 8mA, and a current transfer ratio ranging from 20% to 50% at 16mA input. Typical switching times are 350ns for turn-on and 300ns for turn-off.
Feature Summary
- Provides high-voltage isolation between input and output circuits using photovoltaic transistor technology.
- Designed for surface mount applications in compact electronic assemblies.
- Capable of operating across a wide industrial temperature range.
Applications
- Signal isolation in digital communication interfaces
- Microcontroller input/output protection
- Power supply feedback loops
Procurement Notes
Verify the specific datasheet version from QT Brightek to confirm pinout compatibility and absolute maximum ratings before integration. Ensure that the thermal management strategy accounts for the specified operating temperature range of -55°C to +100°C. Confirm that the 3750Vrms isolation rating meets the safety requirements of the target application environment.
Selection Notes
Select this component when a single-channel isolated interface with transistor output is required. Consider the 3750Vrms isolation level and the specific current transfer ratio characteristics at 16mA. Evaluate the 5-pin Mini-Flat footprint against available board space constraints. Verify that the 8mA output current capability aligns with the load requirements of the receiving circuitry.
Part Context
This component belongs to the family of optoisolators produced by QT Brightek, designed for galvanic isolation in electronic systems. These devices separate circuits electrically while allowing signal transmission via light. The QTM452T1 specifically targets applications requiring robust isolation in a small form factor, distinguishing itself through its photovoltaic output stage and wide temperature tolerance.
Replacement Considerations
HCPL-M453-500E from Broadcom Limited is identified as a parametric equivalent substitute. Verify pinout and electrical specifications against official datasheets before substitution.
