80-V Resistor-Equipped Transistors from Nexperia

Nexperia has released a family of space- and cost-saving 80-V resistor-equipped transistors (RETs) or digital transistors to handle spikes and pulses in 48-V automotive board net (mild hybrids and electric vehicles) and other higher voltage circuits.

These new RETs can 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. Additionally, these high-voltage devices can also be used in general-purpose switching and amplification and other digital systems.

Nexperia also offers double RETs (two transistors and two matching bias resistors and bias-emitter resistors) that are available in the SOT363 package with a Ptot of 350 mW for greater integration and savings. The new series (NHDTx and NHUMx) includes 42 parts with PNP / NPN combinations. These AEC-Q101 qualified devices come with the same bias resistor combinations as Nexperia’s 50 V parts and have a 100 mA current capability.

These devices offer 100 mA, 500 mA, and up to 800 mA output current capability. Key applications include controlling IC inputs, digital systems, and switching loads in automotive, industrial, and communications applications. Integrated bias resistors offer a +/-10% resistance ratio tolerance.

Key Features of 80-V Resistor-Equipped Transistors (RETs)

  • ± 10% resistance ratio tolerance
  • Reduces pick and place costs
  • Built-in bias resistors
  • Reduces component count
  • 100 mA, 500 mA, and up to 800 mA output current capability
  • Simplifies circuit design

Around 400 single and dual RETs are available in a variety of resistor combinations in both surface-mount and leaded packages. Check out 80-V RETs in SOT23, SOT323, and SOT363 from the company website.
