Overview
The 2N6427 TRE PBFREE is an NPN silicon Darlington transistor manufactured by Central Semiconductor Corp. It is housed in a TO-92-3 (TO-226-3) through-hole package and features lead-free construction compliant with RoHS standards. The device is rated for a maximum collector current of 500mA and a collector-emitter voltage of 40V. Designed for small-signal applications, it provides high current gain suitable for circuits requiring significant amplification at low currents.
Feature Summary
- NPN silicon Darlington configuration providing high current gain
- Through-hole TO-92-3 package for standard board mounting
- Lead-free construction adhering to environmental regulations
Applications
- High-gain amplifier stages
- Switching circuits requiring moderate current drive
- Small-signal processing applications
Procurement Notes
Verify the specific datasheet version from Central Semiconductor Corp to confirm electrical characteristics and mechanical dimensions. Ensure the ordering suffix matches the required tape-and-reel or bulk packaging format if applicable. Cross-reference with authorized distributors to confirm component authenticity and compliance status.
Selection Notes
Select this component when high current gain is required in a compact through-hole package. The 40V rating and 500mA current limit define the operational boundaries. Consider thermal management requirements based on the expected power dissipation in the target application circuit.
Part Context
This part belongs to the family of NPN Darlington transistors offered by Central Semiconductor. The 2N6427 designation indicates a standard military-style numbering system adapted for commercial use. The TRE suffix typically denotes specific packaging or testing criteria defined by the manufacturer.
Replacement Considerations
Equivalent parts include MMBT6427 and generic 2N6427 variants from other manufacturers such as ON Semiconductor or Fairchild. Verify pinout compatibility and absolute maximum ratings before substitution.
