Jaycar C122E SCR – 500 V 8 A, TO-220AB, POWER GLAS Glassivated (ZX7012)

Your load is drawing more current than that little TO-225 can handle, and you need headroom without rewriting the whole board. The C122E is a 500 V, 8 A molded silicon SCR in a TO-220AB package. It uses the POWER GLAS glassivation process, which bonds the silicon chip to the coating with no voids — that means tighter thermal performance and a junction that doesn't drift after a few thousand cycles. If your circuit is switching heating elements, motor drives, or industrial contactors and you want a part that holds its rating, this is the one. Solder it into the TO-220 footprint, bolt it to a heatsink, and let it do the heavy lifting. Add to cart
