Low capacitance diode arrays extends breakdown voltage range from 3.3V to 36V
Littelfuse, Inc. today introduced the first of a series of bidirectional TVS Diode Arrays (SPA Diodes) designed to protect high-end consumer and wearable electronics from damaging ESD-generating events. The SP1333-01UTG, the first TVS Diode Array in the SP1333 Series, with a breakdown voltage 3.3V, incorporates back-to-back diodes fabricated using a proprietary silicon avalanche technology. This back-to-back configuration […]
Sager Electronics to distribute Traco Power TSM 200 ac-dc supplies
Sager Electronics is now stocking Traco Power’s TXM 200 series compact 200 W power supplies. The TXM 200 series is a family of 200 W encased AC/DC power supplies designed for cost critical applications. It extends the existing TXM series which ranged from 15 to 150 Watt with an additional 200 Watt series. With a compact metal […]

Diode arrays protect PHY chips from ESD and lightning damage
Littelfuse announced the first of a series of TVS Diode Arrays (SPA Diodes) designed to protect two lines of 10/100/1000BaseT Ethernet ports from damage due to sustained overcurrent and overvoltage. Through-package routing permits the SP4031 Series Hybrid Protection Module’s circuitry to protect an Ethernet PHY chip from damage due to events such as electrostatic discharge (ESD) […]
Thru-hole 650-V SiC power Schottky rectifiers handle up to 10 A
Through-hole SICR5650, SICR6650 and SICR10650 Series of 650-V silicon carbide (SiC) Power Schottky Rectifiers provides low total conduction losses and stable switching over temperature extremes. The single-diode SICR5650 and SICR6650 Schottky rectifiers support average rectified currents of 5 A and 6 A respectively, whereas the common cathode, dual-center-tapped SICR 10650 parts are provided with rectified […]
What are diodes? A quick refresher
A diode is a passive component made with semiconductor materials (a chip) that conducts current flowing in one direction but does not conduct current flowing in the opposite direction. The symbol for a diode (to the right in Figure 1) looks something like an arrow pointing in the direction of the forward current. Current flows […]
Trends in discrete power semiconductors
For many years the rumored demise of the discrete semiconductor has been thrown around, says Joe Beck from Central Semiconductor. Everything’s going to be integrated into an IC. It’s all going away. Not true. In fact, there’s more interest in discrete today than in the last 10 or 15 years, Beck says. When engineers try […]
SiC Schottky diodes shrink energy costs and space requirements
GEN2 Series 1,200-V, 3L TO-247 Schottky diodes and GEN2 Series 1,200-V, 2L TO-263 Schottky diodes dramatically reduce switching losses and allow for substantial increases in the efficiency and robustness of power electronics systems. High-efficiency benefits that SiC technologies enable offer multiple advantages to the designers of electric vehicle chargers, data center power supplies and renewable […]
