Frequently Asked Questions
What precautions must be taken when handling Schottky barrier diodes?
Be aware of large reverse current leakage; improper operation can cause thermal runaway, so consider forward and reverse loss during design.
What is the maximum repetitive peak reverse voltage (RRM) rating for this device?
The repetitive peak reverse voltage (V_RRM) rating is 30 V.
Are these diodes suitable for mission-critical systems like medical or aerospace equipment?
No. They are intended for general electronics applications and are not warranted for use in equipment requiring extraordinarily high quality or reliability, such as medical instruments.
What is the recommended thermal resistance (junction to ambient) if the device is mounted on a ceramic board?
The thermal resistance (Rth(j-a)) when mounted on a ceramic board is 140 °C/W (with a soldering land of 2 mm x 2 mm).
