The PMP4201Y is an NPN/NPN matched double transistor housed in a SOT363 (SC-88) surface-mount package. It features fully isolated internal transistors with a collector-emitter voltage of 45 V and a maximum collector current of 100 mA per device. The DC current gain ranges from 200 to 450 at 2 mA, with a transition frequency up to 250 MHz. Total power dissipation is limited to 300 mW at 25 °C ambient temperature. Key matching specifications include an hFE ratio of 0.98–1 and a base-emitter voltage difference of less than 2 mV.
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact tape-and-reel pitch and packing quantity. Confirm that the component status remains active and check for any recent revision history updates before finalizing procurement plans.
Select this component when precise transistor matching is required for analog signal processing. Ensure the design accommodates the 45 V collector-emitter voltage limit and the 300 mW total power dissipation constraint under expected thermal conditions.
This part belongs to the PMP4201 series which includes variants in SOT666 and SOT353 packages. The PMP4201Y specifically utilizes the SOT363 package. Complementary PNP/PNP versions are available as the PMP5201Y.
Direct substitutes include the PMP4201G (SOT353 package) and PMP4201V (SOT666 package). Verify pin compatibility and package dimensions before substitution.
The maximum junction temperature is 150 °C.
Reflow soldering is the only recommended soldering method.
The typical noise figure is 3.3 dB at 1 kHz with a source resistance of 2 kΩ.
