Good Morning ! I agree with Kubeek, it looks more like a diode (possibly a signal diode) e.g., 1N34, etc.. It is possible also that it is in the circuit for surge protection (e.g., crowbar device). If you can tell us what is silkscreened onto the circuit board for it's designation, that would be very helpful in identification. What is the circuit board, that this component is on, from ? That may help identify it as well, at least it will be a possible hint..
