Import Tips
• Document bidirectional output configuration and AC input voltage range (60-280VAC) for proper classification
• Include application notes showing zero-crossing detection function to avoid general diode classification
• Industrial temperature range specs (-55°C to +100°C) support semiconductor device duty treatment
