Overview
The SL55043SD is a high-voltage optoisolator featuring a transistor output with base terminal, manufactured by onsemi. It provides electrical isolation of 5300Vrms for one channel in a compact 6-SMD package. The device operates within an extended temperature range from -55°C to 100°C. This component is designed for reliable signal transmission in applications requiring robust galvanic isolation between input and output circuits.
Feature Summary
- Provides high-voltage electrical isolation for signal integrity
- Features transistor output with accessible base terminal
- Supports surface mount mounting type for automated assembly
Applications
- Industrial control systems requiring isolated signal interfaces
- Power supply feedback loops needing high voltage isolation
- Medical equipment safety isolation barriers
Procurement Notes
Verify current availability status as the SL55043SD may be obsolete or discontinued. Confirm exact package variant and tape/reel specifications if sourcing from secondary distributors. Ensure substitute components meet identical isolation voltage and pinout requirements for direct replacement in existing designs.
Selection Notes
Select this component when high voltage isolation exceeding standard levels is required alongside a transistor output configuration. The base output allows for external biasing control, offering flexibility in switching speed and sensitivity adjustments compared to standard phototransistor outputs without base access.
Part Context
This part belongs to onsemi's portfolio of optoelectronic isolation devices. It falls under the category of transistor output optoisolators, distinct from logic gate or thyristor output types. The 6-SMD package format aligns with modern surface mount technology trends for space-constrained electronic assemblies.
Replacement Considerations
Check for official onsemi recommended substitutes such as the SL55043S or similar series members. Verify that any alternative maintains the 5300Vrms isolation rating and compatible 6-SMD footprint to ensure mechanical and electrical compatibility in the target application.
