HS2DA R3G Equivalent & Substitute Parts

Part Overview

The HS2DA R3G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 1.5 A average rectified current in a surface mount DO-214AC (SMA) package. This part is classified as discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

The HS2DA R3G operates as a fast recovery diode with a reverse recovery time of 50 nanoseconds, suitable for applications requiring efficient rectification at moderate voltage and current levels. The part is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1) and operates across a junction temperature range of -55°C to 150°C.

Due to the discontinued status of the HS2DA R3G at DiGi Electronics, equivalent parts with identical or compatible electrical and mechanical specifications are required for design continuity and component sourcing.

Frequently Asked Questions (FAQ)

Q: Can the HS2DA from Good-Ark Semiconductor be used as a direct replacement for the HS2DA R3G?

A: Yes. The HS2DA from Good-Ark Semiconductor is a parametric equivalent with identical electrical specifications: 200 V reverse voltage, 1.5 A average rectified current, 1 V forward voltage at 1.5 A, and 50 ns reverse recovery time. The part uses the same DO-214AC (SMA) surface mount package. RoHS3 compliance and MSL 1 rating are maintained. No circuit modifications are required.

Q: Why are some substitute parts rated for 1 A instead of 1.5 A?

A: Parts such as ES1D-13-F, ES1D-M3/61T, and CURA103-G are rated for 1 A average rectified current. These parts are suitable for applications where the actual circuit current demand does not exceed 1 A. If the application requires 1.5 A continuous current, either the parametric equivalent HS2DA (Good-Ark) or the higher-rated ES2D-LTP (2 A) must be selected. Parallel configuration of 1 A parts is not recommended without detailed thermal and current distribution analysis.

Q: What is the difference between the various ES1D variants from Vishay?

A: All ES1D variants from Vishay General Semiconductor - Diodes Division maintain 200 V reverse voltage and 1 A average rectified current in DO-214AC packaging. The primary differences are:

ES1D-M3/5AT: Standard industrial grade, 25 ns reverse recovery time, 920 mV forward voltage at 1 A
ES1D-M3/61T: Standard industrial grade, 25 ns reverse recovery time, 920 mV forward voltage at 1 A
ES1DHE3_A/H: AEC-Q101 automotive qualified, 25 ns reverse recovery time, 920 mV forward voltage at 1 A
ES1DHE3_A/I: AEC-Q101 automotive qualified, 25 ns reverse recovery time, 920 mV forward voltage at 1 A

The automotive-qualified variants (ES1DHE3_A/H and ES1DHE3_A/I) are required for applications subject to automotive qualification requirements.

Q: Is the ES2D-LTP a suitable replacement for the HS2DA R3G?

A: The ES2D-LTP is suitable for applications where higher current capacity is beneficial or required. The part provides 2 A average rectified current compared to the original 1.5 A specification, with identical 200 V reverse voltage and DO-214AC packaging. Forward voltage is 950 mV at 2 A, and reverse recovery time is 35 ns. The part is physically compatible with existing PCB designs. However, if the application is current-limited to 1.5 A or less, the parametric equivalent HS2DA (Good-Ark) is the preferred selection to maintain exact specification matching.

Q: Are all substitute parts RoHS3 compliant and MSL 1 rated?

A: Yes. All substitute parts listed in this reference maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level rating, matching the original HS2DA R3G specifications. This ensures compatibility with standard manufacturing processes, storage protocols, and environmental regulations.

Q: What is the significance of reverse recovery time differences among substitute parts?

A: Reverse recovery time (trr) affects switching losses and electromagnetic interference (EMI) characteristics. The original HS2DA R3G specifies 50 ns. Some substitute parts offer improved performance with lower trr values (25 ns for ES1D variants, 35 ns for ES1D and ES2D-LTP). Lower reverse recovery time reduces switching losses and may improve circuit efficiency. However, if the application is designed for the original 50 ns specification, parts with lower trr values are backward compatible and will not cause circuit malfunction. Parts with higher trr values should not be substituted without circuit analysis.

Q: Can I use CGRA4003-G or CURA103-G in place of the HS2DA R3G?

A: CGRA4003-G and CURA103-G are rated for 1 A average rectified current, which is below the original 1.5 A specification. These parts are suitable only for applications where the actual circuit current demand does not exceed 1 A. If the application requires 1.5 A continuous current, these parts are not suitable. The parametric equivalent HS2DA (Good-Ark) or ES2D-LTP (2 A) must be selected instead.

Q: What packaging options are available for substitute parts?

A: All substitute parts listed in this reference use the DO-214AC (SMA) surface mount package, matching the original HS2DA R3G. Packaging variations such as Cut Tape (CT), Tape & Reel (TR), or Digi-Reel® refer to supply format and do not affect the physical component package. The DO-214AC package dimensions and pin configuration remain identical across all parts, ensuring PCB compatibility without design modifications.

Q: Are there any temperature rating differences among substitute parts?

A: The original HS2DA R3G operates across -55°C to 150°C junction temperature. Most substitute parts maintain this range. The ES2D-LTP from Micro Commercial Co operates across -65°C to 175°C, providing extended low-temperature and high-temperature capability. If the application operates within the standard -55°C to 150°C range, all substitute parts are compatible. If extended temperature operation is required, the ES2D-LTP offers additional margin.
