ES2BAH Equivalent & Substitute Parts

Part Overview

The ES2BAH is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as a fast recovery diode with a reverse recovery time of 35 nanoseconds, suitable for standard rectification applications requiring automotive-grade reliability.

The ES2BAH maintains Active product status with full AEC-Q101 automotive qualification and ROHS3 compliance. Equivalent and substitute parts are identified to provide design flexibility for procurement, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative packaging formats are required.

Substitute Part Grouping Explanation

Substitution eligibility for the ES2BAH is determined by strict equivalence across the following critical electrical parameters:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 950 mV @ 2 A
Reverse Recovery Time (trr): 35 ns
Package / Case: DO-214AC, SMA (surface mount)
Operating Temperature - Junction: -55°C to 150°C

Substitute parts must maintain identical electrical ratings and mechanical compatibility. Variations in packaging format (Cut Tape, Tape & Reel, or standard packaging) do not affect functional equivalence but may impact procurement and assembly workflows. Reverse leakage current and capacitance parameters are secondary differentiators when primary electrical specifications are matched.

Engineering Selection Recommendations

ES2BAH (Primary Selection)

The ES2BAH is the recommended primary selection for new designs and active procurement. This part maintains Active product status with full availability and represents the current manufacturing standard from Taiwan Semiconductor Corporation. It carries AEC-Q101 automotive qualification and ROHS3 compliance, meeting stringent reliability and environmental requirements.

ES2B_R1_00001 (Preferred Substitute)

The ES2B_R1_00001 manufactured by Panjit International Inc. is the preferred substitute when ES2BAH availability is constrained. This part is Active in product status and demonstrates superior reverse leakage performance (1 µA versus 10 µA at 100 V), indicating lower standby current characteristics. All critical electrical parameters match the ES2BAH specification. The Tape & Reel packaging format supports high-volume automated assembly workflows. ROHS3 compliance and REACH Unaffected status maintain regulatory alignment.

ES2BA R3G (Secondary Substitute)

The ES2BA R3G is a secondary substitute option available from Taiwan Semiconductor Corporation in Cut Tape packaging format. This part is Discontinued at DiGi Electronics, indicating limited future availability. All electrical parameters are identical to the ES2BAH. Selection of this part should be limited to applications where Cut Tape packaging is specifically required and inventory depletion is acceptable.

Frequently Asked Questions (FAQ)

Q: Can ES2B_R1_00001 replace ES2BAH in existing designs without circuit modification?

A: Yes. The ES2B_R1_00001 maintains identical electrical specifications across all critical parameters: 100 V reverse voltage, 2 A average rectified current, 950 mV forward voltage drop at 2 A, and 35 ns reverse recovery time. The DO-214AC (SMA) package is mechanically and electrically identical. The lower reverse leakage current (1 µA) of the ES2B_R1_00001 represents an improvement over the ES2BAH specification.

Q: What is the difference between the packaging formats listed for these parts?

A: Packaging format refers to the supply method: Standard packaging is the base format, Cut Tape (CT) provides components on continuous tape for manual or semi-automated pick-and-place operations, and Tape & Reel (TR) supplies components on reel format optimized for high-speed automated assembly lines. All three formats contain identical components in DO-214AC (SMA) packages.

Q: Is ES2BA R3G suitable for new production designs?

A: ES2BA R3G is not recommended for new production designs. This part is Discontinued at DiGi Electronics, indicating that future availability cannot be assured. While electrical specifications are identical to ES2BAH, the discontinued status creates supply chain risk. ES2B_R1_00001 is the preferred alternative for new designs requiring a substitute.

Q: Do all three parts meet automotive qualification requirements?

A: The ES2BAH carries explicit AEC-Q101 automotive qualification. The ES2B_R1_00001 and ES2BA R3G specifications provided do not list AEC-Q101 qualification status. For applications requiring automotive-grade certification, the ES2BAH remains the specified selection. Verification of automotive qualification status for substitute parts should be obtained directly from manufacturers when required.

Q: Are there compliance differences between these parts?

A: All three parts are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). No compliance differences exist across these regulatory frameworks. ECCN and HTSUS classifications are identical.

Q: What is the significance of the reverse leakage current difference between ES2BAH and ES2B_R1_00001?

A: The ES2B_R1_00001 exhibits 1 µA reverse leakage at 100 V compared to 10 µA for the ES2BAH. This represents lower standby current consumption and reduced power dissipation in reverse bias conditions. For applications sensitive to leakage current, the ES2B_R1_00001 provides superior performance. For standard rectification applications, this difference is typically negligible.
