Nexperia, the expert in essential semiconductors, has announced the industry’s first 80 V Resistor-equipped Transistor (RET) family.
These new RETs — or digital transistors — provide enough headroom for use in a 48-V automotive board net (e.g. mild hybrid and EV cars), as well as in other higher-voltage circuits. This is particularly true for those that are subject to large spikes and pulses, which the earlier 50-V parts are unable to handle.
RETs save space and reduce manufacturing costs by combining the bias resistor and bias-emitter resistor in the same SOT23 (250 mW Ptot) or SOT323 (235 mW Ptot) package as the transistor. Double RETs (two transistors and two matching bias resistors and bias-emitter resistors) are also available in the SOT363 package, with a Ptot of 350 mW for even greater integration and savings.
The new series (NHDTx and NHUMx) includes 42 parts with PNP/NPN combinations. These come with the same bias resistor combinations as Nexperia’s 50-V parts. Devices have a 100 mA current capability and are AEC-Q101-approved.
“Design engineers working on new EV applications can future-proof their systems with confidence by using Nexperia’s new RETs to simplify circuit design, save PCB space, reduce pick and place time, and increase reliability,” said Frank Matschullat, product group manager at Nexperia. “As well as 48 V automotive circuit driver applications, general-purpose switching and amplification, and other digital systems will benefit from these new high-voltage devices.”
