Nexperia Resistor-Equipped Transistors (RETs)

Space and cost-saving solutions that reduce your component count and simplify circuit design

Nexperia’s Resistor-Equipped Transistors make for excellent space and cost-saving solutions, while addressing the need for faster switching and higher voltages (particularly for automotive and industrial designs).

By combining transistors with their attendant resistors, Nexperia RETs allow you to find the best fit for your application. Within the Nexperia portfolio, you will find single and dual RETs with a great variety of resistor combinations. You can also choose from ranges with SMD and leaded packages.

  • 48V circuit driver applications (80 V RETs)


About Resistor-Equipped Transistors (RETs)

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.

RETs or ‘digital transistors’ provide enough headroom for use in 48 V 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 previous 50 V parts cannot handle.

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