PN4889 PBFREE

Single Bipolar Transistors Overview

The PN4889 PBFREE is a single NPN high-voltage bipolar junction transistor manufactured by Central Semiconductor Corp. It utilizes silicon technology and is housed in a TO-92-3 through-hole package. Key electrical parameters include a collector-emitter breakdown voltage (VCEO) of 150 V, a collector-base breakdown voltage (VCBO) of 150 V, and an emitter-base breakdown voltage (VEBO) of 6 V. The device supports a continuous collector current of 100 mA with a maximum power dissipation of 1 W. DC current gain ranges from a minimum of 40 to a maximum of 300 at specified test conditions. The transition frequency is 400 kHz, and it operates within a temperature range of -65°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to ensure compliance with environmental regulations. The PBFREE designation indicates lead-free plating, which must be confirmed against project requirements. Cross-reference the manufacturer part number with official datasheets to confirm active status and availability before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when a single NPN transistor with high voltage tolerance is required in a through-hole format. Ensure the application current does not exceed 100 mA and that the operating voltage remains below the 150 V breakdown limits. Consider the thermal management capabilities given the 1 W power dissipation rating and the wide operating temperature range.
