BAT42 Description

Short technical summary and product information.

The Vishay Semiconductors BAT42 is a small signal Schottky diode suitable for general purpose applications. It is characterized by a very low turn-on voltage and fast switching characteristics, making it efficient for various electronic circuits.

 

This diode has an absolute maximum repetitive peak reverse voltage of 30V and a forward continuous current rating of 200mA. The surge forward current capability is up to 4A for short durations (tp < 10 ms). Power dissipation is rated at 200mW at an ambient temperature of 65°C.

 

The BAT42 is housed in a DO-35 (DO-204AH) case, weighing approximately 125 mg. It is available in tape and reel (TR) or ammo tape (TAP) packaging options, with standard quantities of 10,000 units per reel or tape.

 

Thermal characteristics include a junction to ambient air thermal resistance of 300 K/W. The operating junction temperature is up to 125°C, with an ambient operating temperature range of -65°C to +125°C and a storage temperature range of -65°C to +150°C.
