Common Rectifier Diodes
A quick reference to several commonly encountered axial-lead diodes, including their typical voltage and current ratings.
6A10 — 6 A, 1000 V
Standard Rectifier.
V<sub>RRM</sub>: 1000 V | I<sub>F(AV)</sub>: 6 A
1N5408 — 3 A, 1000 V
Standard Rectifier.
V<sub>RRM</sub>: 1000 V | I<sub>F(AV)</sub>: 3 A
1N5402 — 3 A, 200 V
Standard Rectifier.
V<sub>RRM</sub>: 200 V | I<sub>F(AV)</sub>: 3 A
1N4007 — 1 A, 1000 V
General-Purpose Rectifier.
V<sub>RRM</sub>: 1000 V | I<sub>F(AV)</sub>: 1 A
1N4148 — 150 mA, 75 V
Small-Signal Switching Diode.
V<sub>RRM</sub>: 75 V | I<sub>F(AV)</sub>: 150 mA
Polarity: In the diode symbol, A = Anode and K = Cathode. On axial diodes, the band normally marks the cathode (K).
Technical note: The specifications above were checked against available manufacturer/distributor documentation. Exact ratings can vary by manufacturer and specific part suffix, so the applicable datasheet should be used for a particular component.
