80 V RETs feature overhead to handle spikes and pulses
Nexperia announced the industry’s first 80 V RET (Resistor-Equipped Transistor) family. These new RETs or ‘digital transistors’ provide enough headroom for use in 48 V automotive board net (e.g. mild hybrid and EV cars) and other higher voltage circuits which are often subject to large spikes and pulses that previous 50 V parts cannot handle. […]
SiC FETs come in TO-247-4L 4-pin Kelvin Sense packages
UnitedSiC, a manufacturer of silicon carbide (SiC) power semiconductors, expands its UF3C FAST Series product offering by introducing an additional range of 650 V and 1200 V high-performance silicon carbide FETs in a TO-247-4L 4-pin Kelvin Sense package option. Based on an efficient cascode configuration, this new series provides designers with very fast switching, high-power […]
Digital isolator IC works at 200 Mbps with low power consumption
To better protect industrial systems from the dangers of high-voltage signals, equipment designers can now turn to the new robust and reliable MAX22445 5kVRMS four-channel reinforced digital isolator from Maxim Integrated Products, Inc. Delivering up to 2x greater throughput at 4x lower consumption versus competing solutions, the MAX22445 provides reliable communication across the isolation barrier to ensure safe operation of compact industrial, […]
New IGBTs carry 650-V blocking voltage, handle 8 A and 15 A
Infineon Technologies AG introduces the next generation TRENCHSTOP IGBT6 technology. With a 650 V blocking voltage, the 650 V TRENCHSTOP IGBT6 discrete device is optimized for specific applications demanding long lifetime, high reliability and efficiency. These are especially major home appliances and small home appliances, industrial sewing machines and general purpose drives which can be found […]
Automatic power control makes laser diodes eye-safe
The new A4 series of compact APC laser diodes offers additional protection for whenever an eye-safe radiation beam is required: As soon as the operating current exceeds a certain level, the automatic power control (APC) shuts down the laser diode. The A4 laser diodes are insensitive to electrostatic discharges of up to 10 kV and […]
A closer look at photodiodes
I have touched on light sensing methods and the amplification of the signals from them in the past, but at a more fundamental level, how do you choose one? What parameters are important? The answer depends, among other things, on the light source (focused or not), the amount of light and its color. Focused or […]
