BC558B_J18Z

Single Bipolar Transistors Overview

The BC558B_J18Z is a PNP silicon small-signal transistor manufactured by onsemi. It features a maximum collector-emitter voltage of 30V and is housed in a TO-92 package. The device is characterized by a minimum DC current gain (hFE) of 75 and a nominal transition frequency (fT) of 300 MHz. Designed for low noise applications, it supports through-hole mounting with three terminals arranged in a cylindrical plastic/epoxy body.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation as onsemi or Texas Instruments, as both entities have produced this component type. Confirm the specific suffix J18Z corresponds to the intended tape and reel packaging format. Ensure the datasheet specifies the exact hFE binning requirements for the B grade to match circuit design constraints.

Single Bipolar Transistors Selection Notes

Select this component when a PNP small-signal transistor with a 30V rating and TO-92 form factor is required. The B-grade current gain ensures consistent amplification performance. Consider the 300 MHz transition frequency for high-frequency signal processing needs within the specified voltage limits.

Single Bipolar Transistors Part Context

This part belongs to the BC558 series of general-purpose PNP transistors. It shares the same electrical specifications as the standard BC558B but includes specific packaging or marking variations indicated by the J18Z suffix. It is widely used in consumer electronics and industrial control systems requiring reliable switching or amplification.
