BD676AS

Overview

The BD676AS is a PNP Darlington transistor manufactured by Fairchild Semiconductor. It features a maximum collector-emitter voltage of 45V and a continuous collector current of 4A. The device is housed in a TO-126 package with three leads. Key electrical parameters include a DC current gain (hFE) minimum of 750 at 1.5A and 3V, and a collector cutoff current of 500nA. The saturation voltage is specified as 2.5V at 30mA base current and 1.5A collector current. It operates within a junction temperature range of -55°C to 150°C.

Feature Summary

PNP Darlington configuration for high current gain
Robust TO-126 through-hole packaging
High DC current gain capability

Applications

General purpose switching applications
Driver circuits requiring high input impedance
Power control modules

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor has been acquired by onsemi. Ensure the part number suffix matches the specific package variant. Confirm RoHS compliance status if required for your assembly process. Check for obsolescence notices or lifecycle changes from the current supplier. Validate the datasheet version against the manufacturing date code.

Selection Notes

Select this component when a PNP Darlington transistor with moderate voltage ratings and high current handling is needed. The TO-126 package suits through-hole mounting requirements. Consider the thermal dissipation capabilities of the package for your specific power load. Verify that the 45V rating meets your circuit's peak voltage demands.

Part Context

The BD676 series belongs to the family of discrete bipolar junction transistors designed for general-purpose amplification and switching. These devices utilize Darlington pair architecture to achieve significantly higher current gains compared to single-transistor designs. The AS suffix typically denotes specific testing or packaging variations within the standard BD676 product line.
