TomGeorge:
Are they real, or a misprint and you have really bought a 60IRLZ44N, which is the left side "wigwam for a goose's bridle"
Geese bridles are pretty cheap I hear.
60 TTL level power MOSFETs, type IRLZ44N, best used for low side power switching. Max current 49A at 60V. 14.5 cents each.
Most MOSFETs I've found that can switch > 1A cost a good bit more. Earlier I paid 80 cents each for 12 other FETs, go figure.
