Package and mounting
The STMicroelectronics TN1610H-6T is a standard-recovery SCR in a TO-220-3 through-hole package, rated for 600 V off-state blocking and 16 A RMS on-state current.
The 16 A RMS (10 A average) on-state current is the continuous load the SCR can carry when the junction stays within the -40°C to 150°C operating range. At full rated current, the 1.6 V maximum on-state voltage drop means about 16 W of dissipation at 10 A average.
Lifecycle and sourcing posture
If you need a functional equivalent for dual-sourcing, the TN1605H-6T is a 600 V, 16 A SCR in the same TO-220 package, but with a 5 mA gate trigger current — the lower gate sensitivity may require a stronger drive circuit.
