Solid State Relay Circuit: PC817 Optocoupler + Triac | Schematic + PCB Design in Altium Designer

In this tutorial, I’ll design a solid state relay (SSR) circuit using a PC817 optocoupler for galvanic isolation and a BT138B-600E triac for high-voltage switching. This circuit replaces mechanical relays with a contact-bounce-free solution for AC loads, ideal for home automation, industrial control, or motor switching. ✅ What You’ll Learn: Schematic Design: How the PC817 optocoupler isolates low-voltage control from high-voltage loads. PCB Layout in Altium Designer 24.4.1: Component placement for thermal management and EMI reduction. Triac Selection: Why BT138B-600E is ideal for 600V AC loads. 🔧 Files Included: Schematic (.SchDoc) PCB Layout (.PcbDoc) BOM (Bill of Materials) 🔗 Download Project Files: ⚠️ Note: This video covers schematic capture and PCB design only (no physical testing).
