Engineering Selection Recommendations

Full Parametric Equivalents (Recommended for Direct Substitution):

S5G-E3/57T, S5GHE3_A/I, and S5GHM3_A/H are complete electrical and mechanical equivalents to the S5G-E3/9AT. All three parts are manufactured by Vishay, maintain active product status, and provide identical voltage, current, and recovery characteristics. Selection between these parts depends on packaging format requirements and automotive qualification needs. S5GHE3_A/I and S5GHM3_A/H carry AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade components. S5G-E3/57T is available in Cut Tape format with significantly higher inventory (30300 units), providing supply advantage for high-volume applications.

Alternative Manufacturer Option (Active Status):

S5GC-13-F from Diodes Incorporated provides full electrical equivalence with extended operating temperature range (-65°C to 150°C versus -55°C to 150°C). This part is actively produced and maintains ROHS3 compliance. Forward voltage specification matches the S5G-E3/9AT at 1.15 V @ 5 A. This option is suitable when extended temperature performance or supply diversification is required.

Discontinued and Legacy Parts (Not Recommended for New Designs):

S5G V7G (Taiwan Semiconductor Corporation) is discontinued at DiGi Electronics and should not be selected for new designs. S5GL-TP (Micro Commercial Co) carries "Not For New Designs" status and exhibits slightly elevated forward voltage (1.2 V @ 5 A). These parts are listed for reference only in legacy system support scenarios.

Current-Limited Alternative (Reduced Rating):

STTH3R04S from STMicroelectronics is not a direct substitute due to reduced current capacity (3 A versus 5 A). This part is suitable only for applications where 3 A average rectified current is sufficient. The part offers faster recovery characteristics (35 ns versus 2.5 µs) and lower reverse leakage (5 µA versus 10 µA), making it applicable to high-frequency switching applications with lower current requirements.

Frequently Asked Questions (FAQ)

Q: Can S5G-E3/57T be used as a direct replacement for S5G-E3/9AT?

A: Yes. S5G-E3/57T is a complete parametric equivalent with identical electrical specifications (400 V, 5 A, 1.15 V forward voltage, 2.5 µs recovery time). The only difference is packaging format: S5G-E3/57T is supplied in Cut Tape format while S5G-E3/9AT is supplied in Tape & Reel. Both are manufactured by Vishay and carry active product status. Selection depends on your assembly equipment compatibility and inventory requirements.

Q: What is the difference between S5GHE3_A/I and S5GHM3_A/H?

A: Both parts are Vishay-manufactured parametric equivalents with identical electrical specifications and AEC-Q101 automotive qualification. The designations indicate different manufacturing batches or qualification lots. Both are suitable for automotive applications requiring AEC-Q101 certification. Inventory levels differ (4423 units for S5GHE3_A/I versus 9018 units for S5GHM3_A/H).

Q: Why is STTH3R04S listed as a substitute if it has lower current rating?

A: STTH3R04S is listed as a manufacturer-recommended alternative for applications where the 5 A current capacity of the S5G-E3/9AT is not required. This part is suitable only for circuits designed for 3 A maximum average rectified current. The part offers faster recovery time (35 ns versus 2.5 µs) and lower reverse leakage, making it preferable for high-frequency switching applications with reduced current demands. Direct substitution is not possible without circuit redesign.

Q: Can I use S5GC-13-F from Diodes Incorporated instead of the Vishay part?

A: Yes. S5GC-13-F provides complete electrical equivalence with identical voltage (400 V), current (5 A), and forward voltage (1.15 V @ 5 A) specifications. The part is actively produced and ROHS3 compliant. An additional advantage is the extended operating temperature range (-65°C to 150°C versus -55°C to 150°C). This substitution is suitable for supply diversification or when extended temperature performance is beneficial.

Q: Is S5G V7G still available for new designs?

A: No. S5G V7G is discontinued at DiGi Electronics and should not be selected for new designs. While the part maintains identical electrical specifications (400 V, 5 A, 1.15 V forward voltage), it is listed for reference only in legacy system support or repair scenarios. For new designs, select from active products: S5G-E3/57T, S5GHE3_A/I, S5GHM3_A/H, or S5GC-13-F.

Q: What does "Not For New Designs" mean for S5GL-TP?

A: "Not For New Designs" indicates that Micro Commercial Co has discontinued active promotion and support of this part. While S5GL-TP maintains the required electrical specifications (400 V, 5 A), it exhibits slightly elevated forward voltage (1.2 V @ 5 A versus 1.15 V @ 5 A). This part should be used only for legacy system maintenance or repair. For new designs, select from active Vishay or Diodes Incorporated alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status. All parts are also REACH Unaffected and classified under ECCN EAR99 for export purposes.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous tape wound on a reel, suitable for high-speed automated assembly equipment. Cut Tape packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume assembly or manual handling. Both formats use identical DO-214AB (SMC) component packages. Selection depends on your assembly equipment and production volume requirements.
