ES2AA Equivalent & Substitute Parts

Part Overview

The ES2AA is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 2 A average rectified current. The device is packaged in DO-214AC (SMA) surface mount configuration and is classified as a fast recovery diode with a reverse recovery time of 35 nanoseconds. This component is suitable for applications requiring efficient rectification in power supply circuits, converter stages, and general switching applications. The ES2AA maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Equivalent substitute parts are identified based on matching electrical performance parameters and mechanical compatibility to support procurement flexibility and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The ES2A_R1_00001 from Panjit International Inc. is a direct parametric equivalent to the ES2AA. Both devices share identical electrical specifications across all critical performance parameters including reverse voltage rating, forward current capacity, forward voltage drop, and reverse recovery time. Both components are packaged in the DO-214AC (SMA) surface mount configuration, ensuring mechanical and thermal compatibility in existing PCB layouts.

Both the ES2AA and ES2A_R1_00001 maintain Active product status and carry ROHS3 compliance certification with MSL 1 (Unlimited) moisture sensitivity rating. This ensures compliance with current environmental and regulatory requirements for electronics manufacturing.

The ES2A_R1_00001 exhibits lower reverse leakage current (1 µA @ 50 V) compared to the ES2AA (10 µA @ 50 V), which represents improved performance in this parameter while maintaining all other specifications.

Selection between these two parts should be based on availability, lead time, and procurement cost, as both devices are electrically and mechanically interchangeable for the specified application requirements.
