Frequently Asked Questions (FAQs)

• What does the "SS14" designation mean?
  The "SS" stands for Surface-mount Schottky, the "1" indicates the 1 Ampere forward current rating, and the "4" indicates the 40 Volts maximum reverse voltage rating.
• Can I use an SS14 instead of a 1N4007?
  Yes, but with caveats. The SS14 has a much lower voltage drop (0.5V vs 1.1V) and faster switching, which is great. However, the SS14 is only rated for 40V, while the 1N4007 is rated for 1000V. Only substitute if your circuit voltage is well under 40V.
• What is the maximum voltage the SS14 can handle?
  The Peak Repetitive Reverse Voltage (V_RRM) is 40V DC. Do not use this diode in circuits where reverse voltage spikes might exceed this limit.
• What is the maximum continuous current rating?
  It is rated for 1A continuous forward current.
• Why choose a Schottky diode over a standard rectifying diode?
  Schottky diodes have a significantly lower forward voltage drop (typically 0.5V compared to 0.7V–1.1V in standard diodes) and switch much faster, making them highly efficient for low-voltage applications and high-frequency inverters.
• How do I identify the positive and negative sides?
  The SS14 has a white or grey band on one end of its black body. This band marks the Cathode (negative terminal). The unmarked side is the Anode (positive terminal).
• What is the actual forward voltage drop of this diode?
  At a full 1A load, the maximum forward voltage drop is 0.5V. At lower currents, the drop will be even smaller (often around 0.2V to 0.3V).
• Is it possible to hand-solder the SMA (DO-214AC) package?
  Yes. While it is a surface-mount device, the SMA package is relatively large (roughly 5mm long) and can be easily hand-soldered with a fine-tipped soldering iron and some flux, though a hot air station is ideal.
• What is the difference between the SS14 and the SS34?
  Both are 40V Schottky diodes, but the SS14 handles 1A of current, whereas the SS34 handles 3A.
