  • Resource: Diode Tutorial
    primarily by the size of the diode chip, and both the material and configuration of the package, Average Current is used, not RMS current. A larger chip and package of high thermal conductivity are both conducive to a higher current rating. Switching The switching speed of a diode depends upon its
  • Technical Reference: Are a Diode and a Rectifier the Same?
    of the varactor diode; wherein the junction capacitance can be varied by varying the reverse voltage. Figure A. In another example, a depiction of the junction FET is shown in figure B. Again, as the reverse gate junction voltage is increased, the depletion region (high resistance region) extends
  • Technical Reference: Why is The Semiconductor Device Called a Tunnel Diode?
    , the depletion region (high resistance region) extends into the conducting n-channel eventually pinching off the N-channel current. Figure B Go to Top. What is the meaning of Vf as it relates to a diode or rectifier?. Vf is the forward voltage drop of a semiconductor. It consists of two components
  • Instrumenting DWDM Laser Diode Production Tests
    subsequent assembly operations. Additional testing may take place after carrier. mounting to ensure that device characteristics have not changed. Because of high added value, testing typically is done at. each major step in a higher level assembly, such as a Laser Diode Module (LDM) used in a DWDM
  • Technical Reference: What is the meaning of Vf as it Relates to a Diode or Rectifier?
    of the varactor diode; wherein the junction capacitance can be varied by varying the reverse voltage. Figure A. In another example, a depiction of the junction FET is shown in figure B. Again, as the reverse gate junction voltage is increased, the depletion region (high resistance region) extends
  • IEC 1000-4-2 ESD Immunity and Transient Current Capability for the SP72X Series Protection Arrays (.pdf)
    The SP720, SP721, SP723, and SP724 are protection ICs with an array of SCR/Diode bipolar structures for ESD and over-voltage protection of sensitive input circuits. They have 2 protection SCR/Diode device structures per input. The SP720 is supplied in 16 lead DIP and SOIC packages and has a total
  • Production Testing of High-intensity, Visible LEDs
    polarity in one. of two ways. A positive current can be sourced through the LED, and a voltage of. less than 1V generally indicates forward polarity of the diode, while a high. voltage indicates breakdown and reverse polarity. The VR test instrument can. then indicate to the device handler whether
  • Capitance and Signal Integrity (.pdf)
    In previous Technical Briefs, it was introduced that Littelfuse offers a family of ESD suppression technologies including ceramic MultiLayer Varistors (MLV's), silicon (SP72x SCR/Diode and SP05xx TVS Avalanche Diode) Arrays, and polymer PulseGuard (R) suppressor products. These products perform
