Nexperia has introduced its 80 V RET (resistor-equipped transistor) family. The company says the new RETs, or “digital transistors,” provide enough headroom for use in 48 V automotive circuits.

RETs save space and reduce manufacturing costs by combining the bias resistor and bias-emitter resistor in the same SOT23 (250 mW P_tot) or SOT323 (235 mW P_tot) 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 P_tot of 350 mW.

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. The devices have a 100 mA current capability and are AEC-Q101-approved.

Product Group Manager Frank Matschullat commented, “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. 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.”
