Single Bipolar Transistors datasheet and documents for AC857CQ-7

AC857CQ-7

Single Bipolar Transistors Overview

The AC857CQ-7 is a PNP small signal transistor manufactured by Diodes Incorporated, housed in an SOT-23 package. It features a collector-emitter voltage (VCEO) of -45 V and a collector-base voltage (VCBO) of -50 V. The device supports a continuous collector current (IC) of -100 mA with a power dissipation (PD) of 350 mW at +25°C on a minimum pad layout. Electrical characteristics include a DC current gain (hFE) range of 420 to 800 at IC = -2.0mA and VCE = -5V. The transition frequency (fT) is specified between 100 MHz and 200 MHz under standard test conditions.

Single Bipolar Transistors Procurement Notes

Verify that the specific part number matches the required hFE binning, as the AC857CQ variant specifies a higher gain range compared to the AC857BQ. Confirm compliance with automotive quality standards if the application requires AEC-Q101 certification. Ensure the ordering suffix corresponds to the correct reel size and quantity per reel specifications provided in the manufacturer documentation.

Single Bipolar Transistors Selection Notes

Select this component when high DC current gain is required for PNP switching or amplification tasks. The AC857CQ offers a distinct gain profile compared to the AC857BQ, providing higher typical hFE values. Consider the thermal resistance and power dissipation limits relative to the PCB copper area and ambient operating temperature to ensure reliable performance within the specified junction temperature range.

Single Bipolar Transistors Part Context

This component belongs to the AC857 series of PNP small signal transistors designed for general-purpose use. It is specifically engineered to meet automotive reliability requirements through AEC-Q101 qualification. The series includes complementary NPN counterparts and variants with different gain bins, such as the AC857BQ, allowing designers to select components based on precise amplification needs.
