Handling Precaution

1) Schottky barrier diodes have reverse current characteristics compared to other diodes. SBDs can cause thermal

runaway when used under high temperature or high voltage conditions. Be sure to take forward and reverse

loss into consideration during design.

2) The absolute maximum ratings denote the absolute maximum ratings, which are rated values that must not be

exceeded during operation, even for an instant. The following are the general derating methods that we

recommend for designing a circuit incorporating this device.

VRRM: Use this rating with reference to (1) above. VRRM has a temperature coefficient of 0.1%/°C. Take

this temperature coefficient into account when designing a device for operation at low

temperature.

IF (AV): We recommend that the worst case current be no greater than 80% of the absolute maximum

rating of

IF (AV) and that Tj be below 120°C. When using this device, take the margin into consideration by

using an allowable Tamax-IF (AV) curve.

IFSM: This rating specifies the nonrepetitive peak current. This is applied only for abnormal operation,

which seldom occurs during the lifespan of the device.

Tj:

Derate this rating when using the device to ensure high reliability.

We recommend that the device be used at a Tj of below 120°C.

3) Thermal resistance between junction and ambient fluctuates depending on the mounting condition of the

device. When using the device, design the circuit board and soldering land size to match the appropriate

thermal resistance value.

4) Refer to the Rectifiers databook for further information.
