Product Overview
Sylvania ECG part number ECG-5636 is a 3-mode silicon bidirectional thyristor (TRIAC) housed in a standard TO-220 package. Engineered as an exact solid-state replacement for AC switching and phase control, it carries a repetitive peak off-state rating of 500V and continuous RMS on-state current capability of 10A. Designed for reliable triggering across Modes I, II, and III with a 50mA gate current threshold, making it ideal for maintaining legacy motor drives, light dimmers, and appliance controls.
Key Features
- Device type: 3-mode silicon bidirectional thyristor (TRIAC)
- Repetitive peak off-state voltage (VRM): 500V
- RMS on-state current (IF RMS): 10A
- Gate trigger current (IGT): 50mA across Modes I, II, and III
- Gate trigger voltage (VGT): 2.5V maximum
- Pinout configuration: Pin 1 Main Terminal 1 (MT1), Pin 2 Main Terminal 2 (MT2 connected to mounting tab), Pin 3 Gate
- Standard TO-220 package with included insulating shoulder washers
Applications
- Replacing failed power control triacs in vintage bench tools, fan controllers, and light dimming circuits
- Servicing legacy AC solid-state relays and industrial process heating controllers
- Hobbyist and maker AC phase angle control projects requiring isolated heatsink mounting
Frequently Asked Questions
Does this triac cross-reference to any other common replacement numbers?
Yes. The ECG-5636 directly crosses to industry replacement part number NTE5636 with identical electrical specifications and pinout.
What hardware is included in the package?
The sealed factory pack includes the TO-220 triac and two insulating shoulder bushings for electrically isolating the tab when mounting to a heatsink.
Why choose this specific Sylvania unit over buying a mystery surplus lot?
Vintage power semiconductors are frequently counterfeit or pulled from unknown service. This is a genuine, verified Sylvania ECG part in its original unopened packaging with clearly legible factory markings, giving you known performance without gambling on bulk pulls. Shipping is an $8 flat rate, free on orders over $28, and ships same or next business day from our Idaho warehouse.
Solid-state power switching from the golden era of repair counter replacements. Drop it onto the heatsink, torque it down, and get your equipment back under control.
