• 18 to 40 VDC (19 to 40 VDC MTW2805S)
• 30 watts
• 300°C
• –55°C to +125°C
• 18 to 40 VDC continuous (19 to 40 MTW2805S)
• 50 V for 50 msec transient
• –55°C to +85°C full power
• –55°C to +1 15°C absolute
• Linearly from 100% at 85°C to 0% at 1 15° C
Notes
1. For MTW2805S, with the remote sense pins connected to the load and no resistance between the output pins and load.
2. A low output impedance power source is required on the input to realize this start-up time. If less than full surge current is available, start-up time

CAUTION
Permanent damage to the MTW2805S will result if pin 6 is shorted to ground. Damage may also result if pin 4 or pin 5 is disconnected from the load
during operation with the remote sense leads connected to the load. If remote sense pins are not connected to the load, the output voltage of the
MTW2805S will rise to approximately 6.2 VDC measured across pins 4 and 5.
