Overview
The T435-600H is a 4A TRIAC from the T4 series, manufactured by STMicroelectronics. It features a rated repetitive peak off-state voltage (VDRM) of 600V and a maximum holding current (Ih) of 35mA. The device utilizes Snubberless™ and Logic Level technology for high commutation performance on AC inductive loads. It operates within a junction temperature range of -40°C to +125°C. The component is housed in an IPAK through-hole package, providing robust insulation capabilities suitable for mains power switching applications.
Feature Summary
- Snubberless™ and Logic Level technology enabling high commutation performance
- Suitable for AC inductive loads including universal motors and electrovalves
- Available in fully insulated package compliant with UL standards
Applications
- Kitchen aid equipments
- Power tools
- Dishwashers
Procurement Notes
Verify the specific suffix 'H' corresponds to the IPAK package type as documented in official STMicroelectronics datasheets. Confirm that the 600V rating aligns with system requirements. Ensure compatibility with logic-level gate drive circuits due to the specified 35mA holding current characteristic. Cross-reference the manufacturing date code against current production status to avoid obsolete stock issues.
Selection Notes
Select this component for general-purpose AC switching where compact through-hole mounting is required. The 4A RMS current rating suits moderate power applications. Verify that the 600V blocking voltage exceeds the peak line voltage plus transients. Consider the thermal resistance of the IPAK package for heatsinking calculations under continuous load conditions.
Part Context
This part belongs to the T4 series of 4A TRIACs designed for snubberless operation. The series includes variants with different voltage ratings (600V to 800V) and packages (DPAK, IPAK, TO-220AB, ISOWATT220). The T435-600H specifically denotes the 600V version in the IPAK package format.
Replacement Considerations
Check for direct substitutes like T435-800H for higher voltage margins or T435-600B for DPAK surface mount alternatives. Verify pinout compatibility before substitution.
