What are the actual responsibilities of a Tech Lead?

Currently, I'm in a job as a Tech Lead, but it's my first time working abroad, specifically in the USA (considering that I've held the same position for over 6 years in my home country). I was surprised to find out that my role required me to code like a regular programmer, in addition to managing the team, taking on the role of a SCRUM master, and handling partially manual deployments. It really surprised me to have so much on my plate, and I wonder if this is what a Tech Lead typically does in the rest of the world.

What do you think guys?
