STTH20003TV1 Equivalent & Substitute Parts

Part Overview

The STTH20003TV1 is a fast recovery diode module manufactured by STMicroelectronics, configured as a 2 Independent diode array rated for 300 V DC reverse voltage and 100 A average rectified current per diode. The device is housed in an ISOTOP package for chassis mount applications. This component is Active in product status and widely used in high-current rectification circuits requiring fast recovery characteristics. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when application requirements permit operation at different current ratings within the same voltage class.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the STTH20003TV1 are qualified based on the following criteria:

Mandatory Matching Parameters:

• Diode Configuration: 2 Independent
• Voltage - DC Reverse (Vr) (Max): 300 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Chassis Mount
• Technology: Standard
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Substitutes rated at 60 A or 90 A are acceptable for applications where the circuit design permits operation at reduced current ratings
• Package / Case: ISOTOP (main part) vs. SOT-227-4, miniBLOC (substitute parts) — both are chassis mount packages with different form factors
• Reverse Recovery Time (trr): Substitutes with faster recovery times (30 ns, 40 ns) are acceptable as they represent improved performance characteristics
• Voltage - Forward (Vf) (Max): Substitutes with higher forward voltage drop are acceptable provided circuit design accommodates the difference

The IXYS HiPerFRED™ series diode modules DSEP2X61-03A and DSEP2X91-03A meet the core electrical and mechanical requirements for substitution while offering alternative current ratings and improved reverse recovery performance.

Parameter Comparison

Engineering Selection Recommendations

STTH20003TV1 (Primary Part) Select this part when the application requires the full 100 A per diode rating and ISOTOP package form factor. This part maintains Active product status with established supply chain availability.

DSEP2X91-03A (Preferred Substitute) This IXYS HiPerFRED™ module is the closest functional equivalent, rated at 90 A per diode with improved reverse recovery time (40 ns vs. 90 ns). The SOT-227-4, miniBLOC package provides a compact alternative to ISOTOP. Select this substitute when the application circuit design permits operation at 90 A per diode and the package form factor is compatible with the PCB layout. This part is Active in product status and ROHS3 Compliant.

DSEP2X61-03A (Secondary Substitute) This IXYS HiPerFRED™ module is rated at 60 A per diode with the fastest reverse recovery time (30 ns). Select this substitute only when the application circuit design is rated for 60 A per diode operation and the SOT-227-4, miniBLOC package is mechanically compatible. This part is Active in product status and ROHS3 Compliant.

All substitute parts maintain compliance with ROHS3 and REACH requirements equivalent to the primary part.

Frequently Asked Questions (FAQ)

Q: Can DSEP2X91-03A directly replace STTH20003TV1 in my circuit?

A: Direct replacement is possible if the circuit design accommodates the 90 A per diode rating (lower than the 100 A rating of STTH20003TV1) and the SOT-227-4, miniBLOC package form factor fits the PCB layout. Both parts share identical 300 V reverse voltage rating, 2 Independent diode configuration, and fast recovery speed classification. The improved reverse recovery time (40 ns vs. 90 ns) in DSEP2X91-03A represents enhanced performance.

Q: What is the difference between ISOTOP and SOT-227-4, miniBLOC packages?

A: Both are chassis mount packages for high-current diode modules. ISOTOP is the package used in STTH20003TV1, while SOT-227-4, miniBLOC is used in the IXYS substitute parts. Package selection depends on PCB layout requirements, thermal management design, and mechanical mounting constraints. Consult package datasheets for dimensional specifications and mounting hole patterns.

Q: Why does DSEP2X61-03A have a lower current rating than STTH20003TV1?

A: DSEP2X61-03A is rated at 60 A per diode compared to STTH20003TV1 at 100 A per diode. This represents a different product tier within the fast recovery diode module category. Selection of this part is appropriate only when the application circuit is designed for 60 A per diode operation. The lower current rating does not affect voltage compatibility or speed classification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. STTH20003TV1, DSEP2X91-03A, and DSEP2X61-03A are all ROHS3 Compliant and REACH Unaffected, meeting equivalent environmental and regulatory requirements.

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

A: Reverse recovery time (trr) indicates the speed at which the diode transitions from forward conduction to reverse blocking. STTH20003TV1 has trr of 90 ns, while DSEP2X91-03A has 40 ns and DSEP2X61-03A has 30 ns. Faster recovery times reduce switching losses and electromagnetic interference in high-frequency rectification circuits. Substitutes with faster recovery times are compatible with applications designed for the primary part.

Q: Can I use DSEP2X61-03A in place of DSEP2X91-03A?

A: Substitution is possible if the circuit design permits operation at the lower 60 A per diode rating. Both parts share the same 300 V reverse voltage, 2 Independent configuration, and chassis mount type. DSEP2X61-03A offers faster reverse recovery time (30 ns vs. 40 ns), which represents improved performance characteristics.
