Several safety features now found in gate driver integrated circuits make it easier for automotive system designs to get ASIL certification. David Divins • Infineon Technologies The Automotive Safety Integrity Level (ASIL) is a risk classification system defined by the ISO 26262 standard for the functional safety of road vehicles. There are four ASIL safety […]

IGBTs feature FRDs and low thermal resistance
Bourns, Inc. entered the insulated-gate bipolar transistor (IGBT) market with the Company’s first high-efficiency 600 V/650 V discrete product line co-packaged with a fast recovery diode (FRD). Designed using advanced trench-gate field-stop technology that provides greater control of dynamic characteristics, the five new Bourns Model BID Series discrete IGBTs deliver lower collector-emitter saturation voltage (VCE(sat)) and lower switching losses compared […]
What’s the difference between Shockley and Schottky diodes?
Neither a Shockley diode nor a Schottky diode are single p-n junction devices. A Shockley diode has a four-layer thyristor structure with a typical forward drop of 800 mV. It’s called a diode because it has two leads. A Shockley diode is essentially a SCR with the gate not connected. In a Schottky diode a […]
Open-drain DMOS transistor arrays optimized for climate control and home appliance designs
Diodes Incorporated has introduced a new transistor array. The DIODES ULN62003A consists of seven 500mA-rated open-drain transistors, where all their sources are connected to a common ground pin. Capable of driving a wide variety of loads, such as solenoids, relays, DC motors, and LED displays, this high-current transistor array is aimed at climate control and home […]
What’s the difference between an IGBT and an IGCT?
IGBTs and IGCTs are four-layer devices that don’t look that different at first glance. But, when you ‘look under the hood’, you find that an insulated gate bipolar transistor (IGBT) and an integrated (sometimes called ‘insulated’) gate commutated thyristor (IGCT) aren’t that similar. A bipolar transistor forms the basis of an IGBT, while an IGCT […]
New 24-V MOSFETs target wireless earphone battery apps
Magnachip Semiconductor Corporation announced that the company has unveiled a new 24V Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) for wireless earphone batteries. The new 24V MOSFET addresses the goal of battery designers for long battery life after a quick charge by reducing conduction loss. The core cell density of this new product has been increased by 30% […]
Rad-hard 100-V GaN transistor offers lowest on-resistance
EPC has introduced the EPC7018 radiation-hardened GaN FET. The EPC7018 is a 100 V, 3.9 mΩ, 345 APulsed, rad-hard GaN FET in a small 13.9 mm2 footprint. The EPC7018 has a total dose radiation rating greater than 1 Mrad and SEE immunity for LET of 85 MeV/(mg/cm2). The EPC7018, along with the rest of the […]
