  • What are Diodes? - Comparison of Features of Rectified Diodes
    The diodes discussed in this chapter are devices with high withstand voltages and the ability to handle large currents, but they can be classified into several categories according to their characteristics, features, and manufacturing processes. Diode characteristics and performance are basically
  • AG312: Design with PIN Diodes
    is a current controlled resistor at radio and microwave frequencies. It is a silicon semiconductor diode in which a high resistivity intrinsic I-region is sandwiched between a P-type and N-type region. When the PIN diode is forward biased, holes and electrons are injected into the I-region
  • Semiconductor Micromachining Using Diode-Pumped Solid-State Lasers
    ) industries for aplications including wafer dicing, scribing, direct via forming, and three-dimensional structuring. In the current study, two Qswitched and one mode-locked diode-pumped solid-state (DPSS) 355 nm lasers have been used to scribe grooves on silicon and sapphire wafer substrates
  • Techniques to Increase High-Voltage Common Mode Rejection (HVCMR)
    The ACPL-M61L is an optically coupled ultra-low power. 10 MBd digital CMOS optocouplers that operates with. low power consumption, especially when the light. emitting diode (LED) operates at low current. It is off ered. in a compact SO-5 package. When a low current is used. to drive the LED, common
  • * Optimizing High-Voltage Common Mode Rejection Performance of the APCL-x6xL Ultra-Low Power Optocouplers
    The ACPL-x6xL products are optically coupled ultra-low. power 10 MBd digital CMOS opto couplers that operate. with low power consumption, especially when the light. emitting diode (LED) operates at low current. When. a current is applied to drive the LED, common mode. rejection (CMR) can be aff
  • Using Low Resistance MOSFETs as Load Switches
    a resistor and therefore Ohms law applies; when turned off, the MOSFET appears as a diode and as such blocks current in one direction with a very high resistance (if reverse protection is required, an additional MOSFET or blocking diode is required). P-channel MOSFETs are normally used
  • How to Choose Power FETs for ORing MOSFET Controllers
    Using ORing controllers and power FETs in place of ORing power diodes can minimize power loss in high-current power distribution systems. This article discusses key selection steps for choosing power FETs, and provides design tips to ensure engineers meet their target specifications when developing
  • Optocoupler Performance Comparison: NEC PS9552 vs. Avago HCPL-3120
    Both the PS9552 and HCPL-3120 are optically-coupled isolators that employ a GaAlAs LED on the input side and a photo diode, a signal processing circuit, and a power output transistor on the output side. They feature large peak output current, fast switching speeds, undervoltage lockout protection
