KTC4075-Y-TP

Single Bipolar Transistors Overview

The KTC4075-Y-TP is an NPN epitaxial planar bipolar junction transistor manufactured by MCC. It features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 150 mA. The device has a maximum power dissipation of 100 mW and a transition frequency of 80 MHz. DC current gain (hFE) is specified at a minimum of 120 under test conditions of 2 mA collector current and 6 V collector-emitter voltage. Collector-emitter saturation voltage is limited to 250 mV at 10 mA base and 100 mA collector currents. Leakage current (ICBO) is capped at 100 nA. The component operates within a junction temperature range up to 150°C and is housed in a SOT-323 surface-mount package.

Single Bipolar Transistors Procurement Notes

Verify the obsolete status of this part number before design finalization, as manufacturing may have ceased. Confirm availability through authorized distributors or check for direct substitutes if long-term supply stability is required. Ensure the replacement component matches the original electrical specifications and physical footprint to maintain circuit integrity without redesign.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring small-signal NPN switching with moderate voltage ratings. The SOT-323 package suits high-density PCB layouts. Consider the 100 mW power limit when designing thermal management strategies. Verify that the 50 V breakdown voltage meets the circuit's peak operating requirements to prevent device failure under transient conditions.
