The MMDT2227-7-F is a complementary NPN/PNP small-signal transistor array manufactured by Diodes Incorporated. It integrates one 2222A-type NPN and one 2907A-type PNP transistor within a single SOT363 package. The device supports a maximum continuous collector current of 600 mA for both polarities. Voltage ratings include a collector-base voltage (VCBO) of 75 V for the NPN and -60 V for the PNP, with a collector-emitter breakdown voltage (BVCEO) of 40 V and -60 V respectively. Power dissipation is rated at 200 mW, and the junction-to-ambient thermal resistance is 625 °C/W. Operating temperature ranges from -55°C to +150°C.
Verify component authenticity through authorized distribution channels or direct manufacturer verification. Confirm that the ordering suffix '-7-F' corresponds to the standard reel packaging configuration as documented in official datasheets. Ensure compliance with specific environmental requirements such as RoHS and halogen-free standards if mandated by the end-use application regulations.
Select this component when a matched complementary pair is required in a minimal footprint. The SOT363 package offers space efficiency compared to discrete mounting. Verify that the 40V/60V voltage ratings and 600mA current limits align with the circuit's operational demands. Consider the 200mW power dissipation limit and thermal management requirements for the intended operating environment.
This part belongs to the MMDT2227 series of complementary small-signal transistors. It serves as a surface-mount alternative to through-hole complementary pairs. The 'K27' marking code identifies the specific product type within the SOT363 package. An automotive-compliant variant, MMDT2227Q, is available under a separate datasheet for qualified applications.
