Aircraft
[I] departed as pilot flying. At 10;000 FT as I started to accelerate to climb speed; I noticed the aircraft was not trimming in the nose down direction and wanted to pitch up. I told the Captain I thought we might have a trim problem; and passed control of the aircraft to him to try. He found the same results; returned control of the aircraft to me; and got out the QRH. I took ATC on the radio; while the Captain ran the QRH checklist and contacted Maintenance Control. In the course of evaluating the malfunction with maintenance; and after discussing the Circuit Breaker reset policy; we elected that as a flight control system malfunction; it was within the Captain's authority and would be prudent to attempt one reset of a popped Circuit Breaker. The popped Circuit Breaker was reset and immediately popped again when nose down trim was selected. At this point; we completed the QRH; and began a diversion. An uneventful; heavyweight; flaps 15 (per QRH) landing was accomplished. Stabilizer Trim system failed sometime after the trim was set for takeoff. (Note: aircraft was trimmed nose down to set takeoff trim during normal checklist operations and functioned correctly at that time).

A B737-800 Stabilizer Trim failed after takeoff without a failure annunciation when the circuit break popped; was reset and popped again; so the flight diverted to a nearby airport.
