Overview
The CMKT5088 TR PBFREE is a surface mount dual silicon NPN/NPN transistor pair housed in an SOT-363 ULTRAmini™ package. It features a collector-base voltage of 35 V and collector-emitter voltage of 30 V for the NPN devices. Continuous collector current is rated at 50 mA with power dissipation of 350 mW. The component operates within a junction temperature range of -65 to +150 °C. Electrical characteristics include a minimum hFE of 300 at IC=0.1mA and a transition frequency (fT) of 50 MHz at IC=500μA. Marking code is K88.
Feature Summary
- Space-saving SOT-363 ULTRAmini™ package design
- Dual NPN transistors integrated into a single unit
- Optimized for high gain and low noise applications
Applications
- High gain amplifier circuits
- Low noise signal processing stages
- Compact surface mount designs requiring complementary or matched NPN pairs
Procurement Notes
Verify the PBFREE suffix confirms lead-free plating compliance as specified by Central Semiconductor Corp. Ensure the TR designation matches required reel packaging quantities. Confirm the K88 marking code aligns with incoming inspection requirements. Cross-reference the datasheet revision date against manufacturing lot codes for accuracy.
Selection Notes
Select this component when two matched NPN transistors are required in a minimal footprint. The SOT-363 package suits dense PCB layouts. Verify that the 50 mA continuous current rating meets circuit demands. Check thermal resistance limits for expected operating temperatures. Ensure the 30 V collector-emitter voltage exceeds peak circuit voltages.
Part Context
This part belongs to the CMKT50xx series of dual silicon transistors from Central Semiconductor Corp. It complements the CMKT5078 (NPN/PNP) and CMKT5087 (PNP/PNP) variants. All share the same SOT-363 mechanical outline and ULTRAmini™ branding. The series targets applications needing multiple transistors in reduced space.
Replacement Considerations
Direct substitutes require matching NPN/NPN configuration, SOT-363 package, and similar electrical ratings. Verify pinout compatibility: Emitter Q1, Base Q1, Collector Q2, Emitter Q2, Base Q2, Collector Q1. Ensure replacement parts meet the 50 mA current and 30 V voltage specifications.
