Microchip has announced a family of non-hermetic plastic uni-directional TVS (transient voltage suppressor) devices that meet the MIL-PRF-19500/716 for aerospace and defence. “These TVS devices are the first in the industry to achieve MIL-PRF-19500 qualification in a plastic package,” claimed the company. Voltage ratings range from 5V to 175V, and Microchip lists several variants: JANPTX1N5555UJ JANPTX1N5558UG JANPTX1N5629AUJ JANPTX1N5665AUG JANPTX1N5907UG JANPTX1N5907UJ ...

Diodes has introduced a pair of 80V ideal diode controllers to protect against reverse connections and voltage transients. Minimum operating voltage is 3.2V. “The controllers have all the features necessary to implement a fast reverse polarity protection circuit. They also include a load disconnect function in case of over-voltage and under-voltage events,” according to the company. “Unlike ideal diodes with ...

Nexperia has created a 20A 1,200V SiC Schottky diode, using a merged PiN structure to increase surge current capability. For 10ms half-sine pulses its rating is 135A, 91A2/s at 25°C, and 100A, 50A2/s at 150°C. A square pulse of 710A can be withstood for 10μs at 25°C. There is a choice of packaging for the same die: PSC20120L has a ...

Vishay Intertechnology has announced the third generation of its 650 and 1,200V SiC (silicon carbide) Schottky diodes, in a 2.6 x 5.2mm surface-mount package. The DO-221AC package, branded ‘SlimSMA HV’, has a 3.2mm minimum creepage distance. “The diodes offer a 0.95mm profile compared to 2.3 mm for competing SMA and SMB packages,” said Vishay. “Their package features a moulding compound ...

Nexperia has created ESD protection diodes for 48V vehicle communications networks. “Until now, automotive equipment manufacturers lacked suitable ESD protection solutions specifically designed for 48V data lines,” claimed Nexperia head of protection devices Alexander Benedix. “As a result, they often had to rely on workarounds – either including an additional 12 V power rail or connecting several lower-voltage protection diodes ...

X-Fab has improved 25V isolation for better SPAD integration in its 180nm XH018 fab process. 4×3 SPAD arrays: Original Isomos1 and new Isomos2 (right) SPADs – single-photon avalanche diodes – are used as optical receivers in lidar, 3D imaging, depth sensing and quantum communication. The improved isolation module, called Isomos2, improves pixel density and fill factor. “In a typical 4×3 ...

Phlux Technology has announced 1550nm avalanche photodiode with a 3.5GHz cut-off. Part of its existing Aura range, the speed increase comes from a reduced die size, down to 30µm from 80µm (1.8GHz) or 200µm (700MHz), which drops capacitance to between 0.15 and 0.4pF. “This makes it ideal for high-speed, time-critical applications, such as those found in gigabit speed optical communications, ...

Hamamatsu Photonics has launched a series of avalanche photo diodes that work across 320 to 1,000nm. Sensitivity peaks at 750nm. Called the S17353 series, they share a typical sensitivity of 0.44A/W at 650nm, and the six models vary in photosensitive diameter from 0.2 to 5mm. The smallest has a capacitance of 1pF and can be esxpected to work at 1GHz ...

Diodes has introduced some 650V SiC Schottky diodes, rated at 4, 6, 8, 10 or 12A. Called the DSCxxA065LP series, they come in a 8 x 8 x 1mm T-DFN8080-4 package. The company claims a leading Qc x Vf figure-of-merit, but does not include the numbers in its data sheets, so Electronics Weekly unleashed its calculator to find typical 25°C ...

Hamamatsu has launched a family of InGaAs photodiodes with sensitivity across 0.9 to 2.6μm and with a choice of sensitive areas. “The G1719x series are near-infrared sensors offering high sensitivity and low dark current, comparable to conventional metal packages, while featuring a surface-mounted ceramic design compatible with lead-free re-flow soldering,” according to the company. They are “tailored to meet the ...
