Digital transistors are first at 80V, says Nexperia

To overhead spikes and pulses, the Resistor-Equipped Transistors (RETs) have overhead to handle spikes and pulses, says Nexperia, for 48V automotive and other higher voltage bus circuits.

They are the industry’s first 80V RETs, says the company. They are designed for use in 48V automotive board net (e.g. mild hybrid and EV cars) and other higher voltage circuits which are often subject to large spikes and pulses that 50V parts cannot handle.

RETs combine the bias resistor and bias-emitter resistor in the same SOT23 (250mW Ptot) or SOT323 (235mW 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 350mW for even greater space savings.

The NHDTx and NHUMx RETs include 42 parts with PNP / NPN combinations. They have the same bias resistor combinations as Nexperia’s 50V parts, with a 100mA current capability. They are AEC-Q101-approved.

Frank Matschullat, product group manager at Nexperia advised design engineers working on new EV applications can future-proof their systems, simplify circuit design, save PCB space, reduce pick and place time and increase reliability. Target applications are digital systems, such as 48V automotive circuit driver applications, general purpose switching and amplification systems.

80 V RETs in SOT23, SOT323 and SOT363 are available now.

Nexperia produces semiconductors, components, including diodes, bipolar transistors, ESD protection devices, MOSFETs, GaN FETs and analogue and logic ICs.

The company is headquartered in Nijmegen, the Netherlands and has employees across Asia, Europe and the US. Nexperia is a subsidiary of Wingtech Technology, with an extensive IP portfolio and is certified to IATF 16949, ISO 9001, ISO 14001 and OHSAS 18001.
