2SC6043

Single Bipolar Transistors Overview

The 2SC6043 is a 50V, 2A NPN single bipolar transistor manufactured by onsemi. It utilizes the MBIT process to achieve low collector-to-emitter saturation voltage and high-speed switching capabilities. Key electrical ratings include a maximum collector current of 2A (4A pulse), a collector-to-base voltage of 80V, and a DC current gain ranging from 200 to 560 at 100mA. The device features a turn-on time of 35ns and operates within a junction temperature range up to 150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix when purchasing. The standard 2SC6043 is supplied in bags of 500 pieces, while the 2SC6043-AE variant comes in boxes of 1,000 pieces. Confirm package type MP and lead-free status with the supplier before finalizing orders to ensure compatibility with assembly requirements.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring fast switching speeds and low saturation voltage in compact designs. The SC-51/TO-92 package suits space-constrained environments. Ensure base drive currents are sufficient to maintain low VCE(sat) during high-load operations. Validate thermal management for continuous 2A loads to stay within the 1W dissipation limit.

Single Bipolar Transistors Part Context

This part belongs to onsemi's lineup of general-purpose NPN power transistors designed for efficient switching. It serves as a robust alternative for legacy circuits requiring reliable high-current handling in small form factors. The MBIT process technology differentiates it from standard planar transistors by offering improved switching dynamics.

Single Bipolar Transistors Replacement Considerations

Cross-reference pinouts carefully when substituting. Verify that replacement devices support the required 2A continuous current and 50V breakdown voltage. Check if the substitute offers comparable hFE ranges and switching times to maintain circuit timing integrity.

Single Bipolar Transistors FAQ

What is the typical DC current gain (hFE) at 100mA?

The DC current gain typically ranges from 200 to 560 when tested at VCE=2V and IC=100mA.

What is the maximum collector current rating?

The absolute maximum continuous collector current is 2A, with a pulse rating of 4A.

Does the 2SC6043 support surface mount mounting?

No, the 2SC6043 uses the MP package (equivalent to SC-51 or TO-92), which is a through-hole component.
