Diode - standard recovery rectifier, 3A, 1000V, 1N5408
1N5408 Diode. Lead mounted standard recovery rectifiers are designed for use in power supplies and other applications having need of a device with the following features:
  • High Current to Small Size
  • High Surge Current Capability
  • Low Forward Voltage Drop
$0.38
Diode - 1N34A Germanium, low leakage
The 1N34A Germanium diode is an old standby in electronics. Widely used for detecting the rectifying efficiency or for switching on a radio, TV or stereo etc.
$1.75
Diode - Fast Recovery, 1A, 600V, 1N4937
A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.
$0.20
Diode - Silicon Rectifier, 3A, 400V, 1N5404
A semiconductor device which passes current in the forward direction(from anode to cathode), and blocks current in the opposite direction.
$0.35
Diode - small signal fast switching, 1N4148A
A semiconductor device which passes current in the forward direction(from anode to cathode), and blocks current in the opposite direction. For extreme fast switches.
$0.50
Diode - Zener, 1W, 1N4741A, 1N4748A
A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.
$0.20
Diode - 1N5817, Schottky, High Switching Speed
Schottky diode with low forward voltage drop and high switching speeds.
$0.15
Diode - General purpose rectifier, 1A, 1N400X
A semiconductor device which passes current in the forward direction (from anode to cathode), and blocks current in the opposite direction.
Starting at $0.15
