New Yorker Electronics is aiming at displacing PowerPAK 1212 packaged mosfets by stocking a pair of symmetric 80V n-channel mosfets in a single 3.3 x 3.3mm package from Vishay. Called SiZF4800LDT, the “device provides designers with a space-saving solution for synchronous buck converters, point-of-load converters, and half-bridge and full-bridge power stages,” according to New Yorker. “In these applications, the high ...

Small top-side cooled automotive mosfets keep heat out of the PCB
Infineon is aiming at automotive power control with a 5 x 7mm top-side cooled surface-mount package, pitching it against the 5 x 6mm bottom-cooled SSO8. The package, SSO10T, has a 10μm gap instead of a thermal pad on the PCB side, and around 95% of heat will leave through the top, according to the company, typically to the ECU housing ...
Compact hybrid capacitors are AEC-Q200 compliant
Panasonic Industry has introduced compact surface-mount electrolytic polymer hybrid capacitors that are “one size smaller than ZC series with the same capacitance” and AEC-Q200 compliant for automotive use, it said. Called the ZL series, the parts come in five case sizes from 5mm diameter (ø) x 5.8mm high (47 or 82μF), to 10ø x10.2mm (470 or 680μF). There are two ...
GaN, SiC and Si squeeze 4.5kW out of server PSU
Navitas Semiconductor has demonstrated a 4.5kW 54V server power supply using both GaN and SiC transistors. Claimed density is “over 130W/in3 with efficiency over 97%. The architecture replaces the standard four diode bridge (and boost power factor correction) at the front end with an active all-transistor circuit – a multi-phase totem pole power factor corrector. While often called ‘bridgeless’ because ...
2kV SiC mosfet in TO-247 has 14mm creepage and 5.4mm clearance
Infineon Technologies has put 2kV silicon carbide mosfet die in its four lead TO-247PLUS-4-HCC package, aiming them at systems with dc links up to 1.5kV. “It is the first discrete silicon carbide device with a breakdown voltage of 2,000V on the market, with a creepage distance of 14mm and clearance distance of 5.4mm,” according to the company. “The devices are ...
GHz baluns and couplers in 0603 packaging
Component distributor Richardson RFPD is to stock a range of 0603 (1.5 x 0.7mm) RF components from TTM Technologies, all branded ‘Xinger’ and “designed to meet the density and performance challenges of next-generation 5G transceiver and power amplifier applications”, according to Richardson. They include: Three Xinger 90° 3dB hybrid couplers at 1.8 – 2.3GHz, 2.2 – 2.8GHz or 3.1 – ...
APEC: 1mΩ 100V GaN transistor has dual-side cooling
EPC is claiming “the lowest on-resistance GaN FET on the market” for its 1mΩ 100V EPC2361, which comes in a 3 x 5mm QFN package with top and bottom cooling. 1mΩ is at 50A 25°C with 5V on the gate, and rises to ~1.8mΩ at the max operating temperature of 150°C (minimum is -40°C). The preliminary data sheet has no ...
Low-leakage 100V trench Schottky diodes for industrial and automotive
Rohm has created a proprietary trench MOS structure for 100V Schottky diodes to improve the trade-off between forward voltage and reverse leakage. It has been used to create the YQ series of rectifier diodes, available in surface-mount packages from 0.5 x 1mm to TO-263 with ratings between 1A and 30A. Most of them are available with automotive qualification. Leakage is ...
100V bi-directional GaN transistor switches power rails
Innoscience Technology has launched a 100V bi-directional GaN-on-silicon bi-directional transistor, intended to replace a pair of back-to-back mosfets for turning a power rail on and off. It “can be employed in 48V or 60V battery management systems, as well as for high-side load switch applications in bidirectional converters and switching circuits in power systems”, according to the company, which sees ...
P-channel mosfet handles 60V and 90A for Automotive
Toshiba has introduced a 60V p-channel mosfet rated at 60V and 90A continuous current, with AEC-Q101 qualification for automotive use. Called XPH8R316MC (90A), the company sees it being used in vehicles, in load switches, electronic relays and motor drives. A similar part, XPH13016MC, is the same except rated at 60A. In both cases, pulse rating is double the continuous current ...
