BCY59-X TIN/LEAD

Overview

The BCY59-X TIN/LEAD is a discontinued NPN silicon switching transistor manufactured by Central Semiconductor Corp. It utilizes a TO-18 metal can package for through-hole mounting. Key electrical specifications include a collector-emitter breakdown voltage of 45V, a continuous collector current of 100mA, and a maximum power dissipation of 1W. The device features a transition frequency of 150MHz and a DC current gain (hFE) of at least 120 at 2mA and 5V. It operates within a junction temperature range of -65°C to 200°C.

Feature Summary

NPN silicon construction designed for general-purpose switching applications
Hermetically sealed TO-18 metal can package suitable for high-reliability environments
High transition frequency capability for RF and audio signal processing
Wide operating temperature range supporting extreme thermal conditions

Applications

General-purpose low-power switching circuits
Audio amplifier stages
RF signal processing applications
Industrial control systems requiring hermetic sealing

Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of availability requires checking distributor archives or surplus markets. Confirm RoHS compliance status and lead material composition (tin/lead) against specific project requirements before sourcing. Ensure the TO-18 pinout matches the target circuit design.

Selection Notes

Select this part for designs requiring a hermetically sealed NPN transistor with 45V rating and 100mA current capacity. The TO-18 package is preferred over plastic alternatives for radiation resistance or harsh environment durability. Verify that the 150MHz transition frequency meets the signal bandwidth requirements of the intended application.

Part Context

The BCY59 series represents a line of small-signal NPN transistors from Central Semiconductor. The BCY59-X variant specifically denotes the tin/lead plating option within this family. It shares core electrical characteristics with other BCY59 suffixes but differs in terminal finish and potentially specific binning criteria defined by the manufacturer's historical production standards.
