Frequently Asked Questions

What is the maximum repetitive peak reverse voltage ($V_{RM}$) for this diode?

The absolute maximum rating for the repetitive peak reverse voltage ($V_{RM}$) is 40 V.

In what packages (ROHM, JEDEC, JEITA) is the RB731XN available?

It is available in UMD6 (ROHM), SOT-363 (JEDEC), and SC-88 (JEITA) package types.

Is this device suitable for mission-critical life support equipment?

No, if the malfunction could directly endanger human life (e.g., medical or aerospace), consult a sales representative first.

What is the typical forward voltage ($V_F$) of the Schottky diode?

The electrical characteristic shows that the typical forward voltage $V_F$ is 0.37 V when the forward current ($I_F$) is 1mA.
