you can tell by the wider outer Cu pins and narrow middle one - it is a special - most likely automotive - information on what it was chopped out of would be helpful
Standard Teccor SCR had part numbers Sxxxx which are continued at Littelfuse. A69157 looks more like an OEM product for a specific customer, you won't necessarily find a datasheet. Do you expect specific device properties (e.g. GTO feature) or is it just a regular SCR application? In the latter case, what do you really want? Searching a replacement? Identifying a device in your spare box just out of curiosity?

Thanks for the reply
I found it form gem polish machine which control 110v small DC motor. Motor does not use much load but the polisher that connected to the motor shaft.
The input voltage is 230v and the resistor is used to reduced to the 110v and rectified using single diode and smooth capacitor.
