BCY59 PBFREE

Overview

The BCY59 PBFREE is a discontinued NPN bipolar junction 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 45 V, a maximum DC collector current of 100 mA, and a transition frequency of 150 MHz. The device supports a power dissipation of 1 W with an operating temperature range from -65°C to +200°C.

Feature Summary

NPN polarity configuration in a hermetically sealed metal can
High thermal stability supporting extended temperature ranges
Transition frequency suitable for general-purpose amplification

Applications

General-purpose switching circuits
Low-frequency amplification stages
Audio signal processing applications

Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of availability requires checking distributor stock or secondary market sources. Confirm RoHS compliance status and verify that the specific lot matches the required pinout for legacy designs before integration.

Selection Notes

Select this part only if the specific 45V rating and TO-18 form factor are mandatory for the design. Consider modern equivalents if lead-free soldering profiles or surface-mount options are required. Verify that the 100mA current limit meets the circuit's peak load requirements without derating issues.

Part Context

The BCY59 belongs to the Central Semiconductor BCY series of small-signal transistors. It shares the TO-18 package style with related models like the BCY58 and BCY79. This series was designed for robust performance in harsh environments, utilizing metal can construction for superior thermal and mechanical durability compared to plastic packages.
