Pickering Electronics has introduced a single-in-line reed relay  family that mounts on a 0.25inch pitch while switching 80W or 2A. Called Series 144, they feature sputtered ruthenium contacts so they can switch at high power and low-level signals. There is also an internal mu-metal screen to eliminate magnetic interaction between closely stacked devices. Maximum carry current is 3A in all ...

Toshiba is eyeing semiconductor test applications with a tiny photo-relay that operates at 1.6Vin “making it suitable for use with 1.8V FPGAs”, according to the company. “A resistor is built in on the primary side, enabling voltage-controlled operation.” Called TLP3412SRLA, it draws 6.6mA at the nominal operating voltage of 1.8V. Inside is a single Form-A (normally-open) ac or dc contact that ...

Pickering Electronics had added a single-in-line reed relay which can stand-off 5kV and switch 1.5kV to its Series 104. Inside is a single-pole normally-open contact (‘1 Form A’). Footprint is 6.22 x 24.1mm, and the relays stand 8.1mm tall above the PCB. “This is particularly advantageous where a compact design is essential, as the devices can stack at just 6.35mm,” ...

Looking like a general-purpose problem solver for process control, Teledyne Relays has introduced a seven-function DIN rail mount timing relay that works over 100ms to 100 hours and offers a 5A 240Vac change-over (SPDT) contact, that can handle “small inductive loads” at 2.5A. Operation is over a wide range of ac or dc supplies. There are two versions: MFT02A12 12-240Vdc ...

Panasonic has launched a series of 70A PCB-mount power relays designed to US standards “The HE-R2A relay series is suited for modern wall box designs, and we are happy that we can offer a UL508-compliant sibling of the HE-R type for European four-phase systems, enabling the consolidation of switching functions onto PCBs with space savings,” said Panasonic product manager Bernd ...

Toshiba has added over-temperature and over-voltage protection features to an 80V 1.4A photo-relay, all inside a 4pin DIP package. Called TLP241BP, it can switch ac or dc though its single isolate 280mΩ (max) output switch – implemented as a pair of back to back mosfets – and handle pulses up to 4.2A (100ms, 1/10 duty). Output leakage is 1μA max ...

Pickering Electronics will introduce a series of surface-mount >1kV reed relays at Productronica in Munich next week. Series 219 reed relays “can effortlessly switch up to 1kV, and are the only surface mount high voltage relays available in the market in 2 Form A and 1 Form B packages”, according to the company. Some details are available now: stand-off is ...

After announcing 60V opto-mosfet relays last week, this week Panasonic has revealed a 600V type in a 2.65 x 4.45 x1.8mm package. AQY206GV’s 8Ω mosfet (15Ωmax) will switch 600V, and 150mA (450mA pulsed), with a maximum dissipation of 350mW. Its SSOP package is rated for 1,500Vrms isolation, and the whole device will work up to +105°C ambient. Maximuturn on and ...

Panasonic has created a pair of miniature opto-mosfet relays that can handle well over an amp and need little diode current. Both have back-to-back output mosfets, so they can switch ac or dc power, and both come in 4.3 x 6.8 (including leads) x 2.2mm high (SOP4) gull-wing packaging. Days later, it revealed something similar rated at 600V AQY212G3HS can ...

Pickering Electronics has announced 125°C versions of its 104 series high-voltage reed relays. 104HT relays will be available in a 1 Form A configuration (SPST NO) rated to stand-off 4kV. Full data has yet to be unveiled but, using the original (-20 to +85ºC) 4kV 104 relays as a guide, switching capacity is likely to be 1kVdc at 25W, and ...
