Overview
The VO4154H-X007T is a single-channel zero-crossing triac output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates a gallium arsenide infrared LED with a photosensitive zero-crossing triac in a surface-mount SMD-6 package. The device provides an isolation voltage of 5300 Vrms and supports a maximum continuous output current of 300 mA. It features a peak off-state voltage (VDRM) of 400 V and a maximum forward current (If) of 60 mA. The component operates within a temperature range of -55°C to +100°C.
Feature Summary
- Integrates a GaAs IR LED with a photosensitive zero-crossing triac for precise AC load switching
- Provides high-voltage electrical isolation rated at 5300 Vrms between input and output circuits
- Features built-in zero-crossing detection circuitry to minimize electromagnetic interference during switching
Applications
- Solid-state relay (SSR) modules for industrial control
- AC motor speed control circuits
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix 'X007T' confirms the SMD-6 surface mount packaging variant, as standard VO4154 models may utilize DIP-6 through-hole packages. Confirm RoHS compliance status directly from the manufacturer's datasheet or official product change notices prior to final design approval.
Selection Notes
Select this component when surface-mount assembly is required for AC power control applications. Ensure the 400 V peak off-state voltage rating exceeds the maximum line voltage plus transients in the target application. Verify that the 300 mA continuous current capacity meets the load requirements.
Part Context
This part belongs to the VO415x series of zero-crossing triac output optocouplers. The series is designed for efficient AC power switching with low electromagnetic interference. The X007T designation specifically indicates the tape-and-reel surface mount configuration, distinguishing it from the through-hole DIP variants within the same functional family.
Replacement Considerations
The VO4154D-X007T is a documented alternative within the same series offering identical functionality but potentially differing in physical package dimensions or pinout orientation. Verify mechanical footprint compatibility before substitution.
