The EMD9FHAT2R is a dual pre-biased bipolar junction transistor (BJT) array manufactured by Rohm Semiconductor. It integrates one NPN and one PNP transistor within an EMT6 surface-mount package, equivalent to SOT-563 or SOT-666. The device features a maximum collector current of 100mA and a transition frequency of 250MHz. Internal base resistance is 10kΩ, while emitter-base resistance is 47kΩ. DC current gain is specified at a minimum of 68 under test conditions of 5mA collector current and 5V collector-emitter voltage. Maximum power dissipation is 150mW, with a saturation voltage of 300mV at 250µA base current and 5mA collector current.
Verify component authenticity through authorized distribution channels prior to integration. Confirm that the specific revision matches design requirements, as this part carries a not recommended for new design status. Ensure supply chain stability due to potential manufacturing constraints associated with end-of-life management protocols.
Evaluate thermal performance against the 150mW maximum power dissipation limit during circuit simulation. Verify that the 100mA collector current rating exceeds peak load demands. Consider the AEC-Q101 qualification if the application operates within automotive environments requiring strict reliability standards.
This component belongs to the EMD9FHAT2 family of pre-biased transistor arrays. It serves as a surface-mount solution for replacing discrete resistor-transistor networks. The EMT6 package provides space efficiency compared to traditional through-hole alternatives.
Direct pin-compatible substitutes include EMD9FHAT2RCT and EMD9FHAT2RDKR. Verify electrical parameter equivalence before substitution.
