Nexperia announced industry’s first 80 V RET (Resistor-Equipped Transistor) family. These new 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.
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 (more info).
