They are characterised by a maximum VDSS rating of 150V and current handling of 64A. The MOSFETs have low drain-source RDS (on) of just 9.0mΩ (max). This is over 40% less than is possible with the TPH1500CNH1 MOSFET, the previous generation device. For high performance power devices using synchronous rectification, reverse recovery performance is highly important, Toshiba advises. The TPH9R00CQ5 MOSFET includes a high speed body diode which reduces the reverse recovery charge (Qrr) by around 74% (to 34nC typical) when compared to an existing device such as the TPH9R00CQH. The reverse recovery time (trr) is just 40ns which is an improvement of over 40% compared with earlier devices, reports the company. Gate charge (Qg) is just 44nC, further contributing to reduced losses and increased power density. Unusually for a MOSFET, the channel temperature is 175°C (max) which, combined with the high speed diode will offer the designer increased thermal headroom. The MOSFET also reduces spike voltages created during switching, thereby improving EMI characteristics of designs and reducing the need for filtering. The TPH9R00CQ5 is housed in a surface-mount SOP Advance(N) package measuring just 4.9 x 6.1 x 1.0mm. Toshiba has also developed a G0 SPICE model for rapid verification of the circuit function. There are also G2 SPICE models for accurate MOSFETs reduce synchronous rectification losses reproduction of transient characteristics. In addition, there are reference designs, including a 1kW non isolated, buck-boost DC/DC converter, a three-phase multi-level MOSFET-based inverter and a 1kW full bridge DC/DC converter, all of which use the TPH9R00CQ5. The TPH9R00CQ5 MOSFET is shipping now. Visit Toshiba Electronics Europe at PCIM Europe 203 – Hall 9 - 503 Kyocera AVX has expanded its SCC series to include six automotivecertified supercapacitors. The cylindrical SCC automotive grade supercapacitors were tested against the requirements of AEC-Q200 std and operate in both mechanically and electrically challenging conditions, said the company, whether in electronic-mechanical locking (e-latch), emergency call systems (e-Call), electronic recording (e-video), regenerative braking, power, and emergency power systems. The automotive-grade supercapacitors have a very low ESR value, high capacitance and “excellent” pulse power handling characteristics. The capacitors meet UL 810A, RoHS and REACH requirements. They are available in 25F / 2.7V, 100F / 2.7V, 10F / 3V, 35F / 3V, 50F / 3 as well as 100F / 3V. To extend back-up times and battery life and to take advantage of instantaneous pulse power, the supercapacitors can be used alone or in conjunction with primary or secondary batteries. Visit Rutronik at PCIM Europe 2023 – Hall 6 - 322 Rutronik expands automotive portfolio with Kyocera AVX supercapacitors Vishay Intertechnology has enhanced the Vishay Draloric RCS0805 e3 antisurge thick film resistor in the 0805 case size with a higher power rating of 0.5 W. It can now be used in place of four standard parallel resistors in the 0805 case size or in place of two parallel devices in the larger 1206 case size or one resistor in the 1210 case size. Designers can save board space in automotive, industrial, telecommunications and medical applications while lowering component counts and reducing placement costs. For applications subject to high and repetitive surge pulses, the resistor also offers superior pulse load performance and ESD surge characteristics when compared to standard chip resistors, says the company. The AEC-Q200-qualified RCS0805 e3 features a resistance range from 1.0Ω to 10MΩ (and 0Ω jumper) with tolerances of ± 0.5%, ± 1% and ± 5%. TCR is ± 100ppm/K and ± 200ppm/K. The resistor offers an operating voltage of 150V and an operating temperature range of -55 to 155°C. They are RoHS-compliant and halogen-free, and therefore suitable for processing on automatic assembly systems as well as for wave, reflow, or vapor phase soldering per IEC 61760-1. Samples of the enhanced RCS0805 e3 are available now, with lead times of 12 weeks. Visit Vishay at PCIM Europe 2023 – Hall 9 – 210
