Product Summary

The BAT42 is a small signal schottky diode. The device is featuring very low turn-on voltage fast switching. The BAT42 has integrated protection against excessivevoltagesuch as electrostaticdischarges.

Parametrics

BAT42 absolute maximum ratings: (1)VRRM, Repetitive Peak Reverse Voltage: 30 V; (2)IF, Forward Continuous Current at Ta= 25℃: 200 mA; (3)IFRM, Repetitive Peak Fordware Current: 500 mA; (4)IFSM, Surge non Repetitive Forward Current at tp = 10ms: 4 A; (5)Ptot, Power Dissipation at Tl= 65℃: 200 mW; (6)Tstg, storage temperature range: -65 to 150℃; (7)Tj, Junction Temperature Range: - 65 to +125℃; (8)TL, Maximum Temperature for Soldering during 10s at 4mm from Case: 230℃.
