These 1-3 A SiGe rectifiers, targeted at the automotive, communications infrastructure, and server markets, are particularly advantageous for high-temperature applications such as LED lighting, engine control units, and fuel injection systems. Design engineers using the new extremely low leakage devices can now rely on a wider operating range without thermal runaway up to 175 °C while simultaneously optimizing for more efficient designs—something not feasible with the fast-recovery diodes typically used in such high-temperature applications. Thanks to their higher forward voltage (Vf) and low Qrr, SiGe rectifiers offer the advantage of reducing conduction losses by 10% to 20%.

These are some of the main features of Nexperia's SiGe rectifiers:

• Excellent efficiency
or reduced reverse current (IR) compared to Schottky diodes, and lower forward voltage (Vf) compared to fast recovery rectifiers for low power losses
or Fast and smooth switching, thermal stability up to 175 °C Tj, extremely low leakage current of < 1 nA, low forward voltage and low Qrr
• Extended safe operating area
or Safe operation at elevated temperatures
or Stable operation at maximum reverse voltage
• Advanced CFP (clip bonded FlatPower) package
or In the tough, industry-standard CFP3 and CFP5 packages, SiGe's rectifier range offers lower package resistance for improved electrical performance
or A solid copper contact clip to increase thermal performance and power dissipation
or Simple pin-to-pin replacement with Schottky and fast recovery diodes
or Reduced package inductance for improved switching behavior and lower parasitic capacitance in the circuit

Incorporating Nexperia's innovative SiGe technology into their designs gives engineers unprecedented options for developing premium power circuits and building new market-leading products. SiGe devices complement Nexperia's power diode portfolio, which includes over 100 Schottky diodes and fast recovery rectifiers in CFP packages. Farnell stocks 12 different products from Nexperia's SiGe rectifier portfolio. The AEC-Q101 compliant rectifiers are available with maximum repetitive reverse voltage (Vrrm) options of 120 V, 150 V, and 200 V and forward IF (AV) current options of 1, 2, or 3 A.

Lee Turner, Global Head of Semiconductors and Single Board Computing at Farnell, comments: “Nexperia is an expert in the mass production of essential semiconductor products, and we are pleased to expand our range of SiGe rectifiers now available from stock. Designers are under constant pressure to achieve better performance in a smaller footprint, and new applications demand the highest system efficiency and maximum miniaturization. It is critical to provide customers with market-leading solutions that offer best-in-class efficiency, ease of thermal design, and a small form factor to support critical applications in the automotive, server, and communications markets.”.

Nexperia's extensive product catalog includes diodes, bipolar transistors, ESD protection devices, GaN MOSFETs and FETs, as well as analog and logic integrated circuits. Headquartered in the Netherlands, Nexperia sells over 90 billion products annually that meet the demanding standards of the automotive industry. These premium products are considered benchmarks for their efficiency (in process, size, power, and performance) with industry-leading small packages that offer valuable savings in power consumption and space.

Nexperia's SiGe rectifiers are now available from Farnell in Europe.
