ABAV23C-HF

Overview

The ABAV23C-HF is a dual high-voltage switching diode manufactured by Comchip Technology, housed in an SOT-23 surface-mount package. It features a common cathode configuration with two independent internal diodes sharing a single cathode terminal. The device is rated for a maximum repetitive peak reverse voltage of 250 V and supports a DC forward current of 225 mA. Designed for robust performance, it operates within a temperature range of -55°C to +150°C and complies with RoHS standards.

Feature Summary

• Dual high-voltage switching diodes integrated into a single compact surface-mount package
• Common cathode configuration simplifies circuit layout and reduces component count
• High thermal stability supporting operation up to 150°C junction temperature

Applications

• Automotive electronic systems requiring high-voltage switching capabilities
• General-purpose surge protection circuits
• High-speed signal switching applications

Procurement Notes

Verify the manufacturer part number ABAV23C-HF against official Comchip Technology documentation to ensure authenticity. Confirm that the marking code KT6 matches the specific batch requirements. Ensure the selected variant strictly adheres to the specified SOT-23-3 package dimensions and electrical ratings for the intended design implementation.

Selection Notes

Select this component when a dual diode solution with common cathode topology is required in a small form factor. The 250 V reverse voltage rating makes it suitable for medium-voltage switching tasks. Consider the 225 mA continuous forward current limit during load analysis. The wide operating temperature range ensures reliability in demanding environments compared to standard commercial-grade alternatives.

Part Context

This component belongs to the ABAV23 series of dual high-voltage switching diodes from Comchip Technology. The series includes variants such as ABAV23A-HF and ABAV23S-HF, which share similar packaging but may differ in specific electrical characteristics or marking codes. The ABAV23C-HF specifically denotes the common cathode configuration within this product family.

Replacement Considerations

Compatible substitutes include ABAV23A-HF and ABAV23S-HF from Comchip Technology, provided the specific electrical parameters align with the circuit requirements.
