Human Factors
My First Officer and I were on day two of a three-day trip. We both prefer night trips; but because of certain days we bid a day line. Today; the second day; we had an [early] report. Fatigue was definitely a factor. I was the PF (Pilot Flying). Part of our takeoff clearance out of BUR was a traffic call about a helicopter flying near the runway. The takeoff was uneventful. I initiated a turn to the right as per the departure procedure. After being handed off to SCT; we were immediately cleared to a higher altitude. Our TCAS system alerted us to traffic in the area. I engaged the autopilot at 1;000 feet; so I could help look for conflicting traffic. We were handed off to a different Controller.Upon initial contact with the Controller; we were instructed to turn immediately to a heading of 180. I cannot recall if the autopilot was in heading select mode because we got the instruction to turn a 180 very quickly and he did use the word 'immediately.' I disengaged the autopilot; initiated a turn to the south to expedite the de-confliction. The Controller instructed us to tighten up the turn immediately due to a traffic conflict. Due to the urgent tone in his voice I rolled into 45 degrees of bank. He told us of a traffic conflict at 3;000 feet. At that point; we had just passed 4;000 feet. After the Controller de-conflicted the situation and the First Officer and I had no idea of what was going on; I asked him on the radio what had just happened. He stated that we had shot through our 210 heading and we were heading right into arrival traffic for BUR.
B737-700 reported experiencing a heading deviation during departure from BUR resulting in an airborne conflict.
