HS2GA R3G Equivalent & Substitute Parts
Part Overview
The HS2GA R3G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 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 production and repair applications. Equivalent parts maintain identical electrical specifications, while substitute parts offer similar functionality within acceptable parameter tolerances for the DO-214AC rectifier diode category.

Substitute Part Grouping Explanation
Substitution of the HS2GA R3G is determined by the following critical parameters:
Primary Substitution Criteria:
- Voltage - DC Reverse (Vr) (Max): 400 V minimum
- Current - Average Rectified (Io): 1.5 A minimum
- Package / Case: DO-214AC (SMA) surface mount
- Mounting Type: Surface Mount
- Operating Temperature Range: -55°C to 150°C minimum
Secondary Compatibility Factors:
- Voltage - Forward (Vf) (Max): ≤ 1.3 V @ rated current
- Reverse Recovery Time (trr): ≤ 50 ns for fast recovery classification
- Current - Reverse Leakage @ Vr: ≤ 5 µA @ 400 V
- RoHS Status: ROHS3 Compliant
- Moisture Sensitivity Level: MSL 1
Parametric Equivalents maintain all primary and secondary specifications identically. Similar Parts may have reduced current ratings (1.0 A instead of 1.5 A) or different recovery time characteristics but remain compatible within the DO-214AC package and 400 V voltage class.

Engineering Selection Recommendations
Parametric Equivalents (Direct Replacement):
The HS2GA manufactured by SURGE is a direct parametric equivalent with identical electrical specifications and active product status. This part is recommended as the primary replacement for the discontinued HS2GA R3G.
The RS2GA and RS2GA R3G from Taiwan Semiconductor Corporation maintain the 400 V / 1.5 A rating and package specification. The RS2GA R3G shares the same manufacturer and product line as the original part. The RS2GA is available in active status with Tape & Reel packaging. The RS2GAH variant includes AEC-Q101 automotive qualification and is recommended for applications requiring automotive-grade reliability certification.
Similar Parts (Reduced Current Rating):
Parts rated for 1.0 A average rectified current (CGRA4004-G, CURA104-G, ES1G-13-F, GS1G-LTP, RS1G-13-F) are suitable for applications where the circuit design permits operation at reduced current capacity. These parts maintain the 400 V voltage rating and DO-214AC package compatibility.
The CURA104-G and ES1G-13-F offer fast recovery characteristics (50 ns and 25 ns respectively) comparable to the original HS2GA R3G specification.
Avoid for New Designs:
Parts designated "Not For New Designs" (GS1G-LTP, GS2G-LTP) are available for legacy system support but should not be selected for new circuit development.
Compliance Considerations:
All listed parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, consistent with the original HS2GA R3G specification.
Frequently Asked Questions (FAQ)
Q: Can I use a 1.0 A rated diode in place of the 1.5 A HS2GA R3G?
A: A 1.0 A rated diode is suitable only if the circuit design ensures that the average rectified current does not exceed 1.0 A. The HS2GA R3G is rated for 1.5 A operation; substitution with lower-rated parts requires circuit analysis to confirm current compliance.
Q: What is the difference between HS2GA and RS2GA?
A: Both parts are rated 400 V / 1.5 A in DO-214AC packages. The primary difference is reverse recovery time: HS2GA has 50 ns (fast recovery), while RS2GA has 150 ns. Both are suitable replacements; selection depends on circuit switching frequency requirements.
Q: Is the RS2GAH automotive-qualified version compatible with non-automotive applications?
A: Yes. The RS2GAH includes AEC-Q101 automotive qualification, which represents a higher reliability standard. It is fully compatible with non-automotive applications and may be selected for enhanced reliability requirements.
Q: Why is the GS2G-LTP listed if it has a 2.0 A rating instead of 1.5 A?
A: The GS2G-LTP is listed as a similar part because it maintains the 400 V voltage rating and DO-214AC package. The higher current rating (2.0 A) provides additional margin but does not prevent use in 1.5 A applications. However, this part is designated "Not For New Designs" and should be used only for legacy system support.
Q: What packaging options are available for equivalent parts?
A: Equivalent parts are available in multiple packaging formats: Bag, Tape & Reel (TR), and Cut Tape (CT). Selection depends on production volume and assembly process requirements. Tape & Reel packaging is standard for high-volume surface mount assembly.
Q: Are all listed parts RoHS3 compliant?
A: Yes. All parts listed in this reference maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, consistent with the original HS2GA R3G specification.
Q: Can I substitute based on forward voltage alone?
A: No. Forward voltage is one parameter among several. Substitution requires matching or exceeding the voltage rating (400 V), meeting or exceeding the current rating (1.5 A), maintaining the DO-214AC package, and confirming operating temperature range compatibility (-55°C to 150°C minimum).
