|---|---|
| Ideal diodes act as perfect conductor and perfect insulator. | Practical diodes cannot act as perfect conductor and perfect insulator. |
| Ideal diode draws no current when reverse biased. | Practical diode draws very low current when reverse biased. |
| Ideal diode offers infinite resistance when reverse biased. | Practical diode offers very high resistance when reverse biased. |
| It cannot be manufactured. | It can be manufactured. |
| It has zero cut-in voltage. | It has very low cut-in voltage. |
| Ideal diode has zero voltage drops across its junction when forward biased. | It has very low voltage drop across it, when forward biased. |
| Ideal diode acts as perfect conductor and perfect insulator. | Practical diode act as perfect conductor and perfect insulator. |
