Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UG2004PTHC0G are qualified based on the following criteria:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 200 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Through Hole
• Package / Case: TO-247-3
• Technology: Standard

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Substitutes may operate at different current ratings provided the application does not exceed the substitute part's maximum rating
• Voltage - Forward (Vf) (Max) @ If: Forward voltage may vary with current rating
• Reverse Recovery Time (trr): May vary within fast recovery classification
• Current - Reverse Leakage @ Vr: May vary within acceptable limits
• Operating Temperature - Junction: Maximum temperature may differ

The identified substitutes STTH3002CW and STTH6002CW maintain all mandatory parameters while offering alternative current ratings of 15 A and 30 A respectively, enabling selection based on specific circuit current requirements.

Parameter Comparison

Engineering Selection Recommendations

UG2004PTHC0G (Main Part): Select this part for applications requiring 20 A average rectified current per diode with 200 V reverse voltage rating. The component carries AEC-Q101 automotive qualification and maintains Active product status. ROHS3 compliance and REACH Unaffected status satisfy regulatory requirements for automotive and industrial applications.

STTH3002CW (Lower Current Alternative): This STMicroelectronics substitute operates at 15 A average rectified current per diode. Select this part when circuit requirements do not exceed 15 A per diode. The part maintains identical 200 V reverse voltage rating, TO-247-3 package compatibility, and fast recovery speed classification. ROHS3 compliance and REACH Unaffected status are maintained. Reverse leakage current is reduced to 20 µA at 200 V compared to the main part.

STTH6002CW (Higher Current Alternative): This STMicroelectronics substitute operates at 30 A average rectified current per diode. Select this part for applications requiring current capacity exceeding 20 A per diode. The part maintains identical 200 V reverse voltage rating, TO-247-3 package compatibility, and fast recovery speed classification. ROHS3 compliance and REACH Unaffected status are maintained. Reverse recovery time is 27 ns, within fast recovery specification.

All three parts are Active products with full regulatory compliance and identical thermal operating range (-55°C to 175°C junction temperature maximum).

Frequently Asked Questions (FAQ)

Q: Can STTH3002CW be used as a direct replacement for UG2004PTHC0G?

A: STTH3002CW is mechanically and electrically compatible with UG2004PTHC0G in applications where the circuit current requirement does not exceed 15 A per diode. Both parts share identical 200 V reverse voltage rating, TO-247-3 package, fast recovery speed classification, and regulatory compliance. The substitute part is suitable only when current demand is within its 15 A specification.

Q: Can STTH6002CW be used as a direct replacement for UG2004PTHC0G?

A: STTH6002CW is mechanically and electrically compatible with UG2004PTHC0G. Both parts share identical 200 V reverse voltage rating, TO-247-3 package, fast recovery speed classification, and regulatory compliance. STTH6002CW provides higher current capacity at 30 A per diode, making it suitable for applications requiring current above 20 A per diode.

Q: What is the significance of the TO-247-3 package compatibility?

A: All three parts utilize the TO-247-3 package format, ensuring identical mechanical fit, pin configuration, and thermal interface characteristics. Through Hole mounting type is consistent across all parts, allowing direct PCB layout compatibility without modification.

Q: How do forward voltage characteristics differ between these parts?

A: The main part UG2004PTHC0G specifies 930 mV maximum forward voltage at 10 A. Both STMicroelectronics substitutes specify 1.05 V maximum forward voltage at their respective rated currents (15 A and 30 A). Forward voltage increases with current rating due to semiconductor physics. Circuit design must account for these differences in power dissipation calculations.

Q: Are all three parts suitable for automotive applications?

A: The main part UG2004PTHC0G carries AEC-Q101 automotive qualification and Automotive grade designation. The STMicroelectronics substitutes STTH3002CW and STTH6002CW do not carry explicit AEC-Q101 qualification in the provided specifications. Automotive application suitability must be confirmed through manufacturer documentation for the substitute parts.

Q: What is the difference in reverse leakage current between these parts?

A: UG2004PTHC0G specifies 200 µA reverse leakage at 200 V. STTH3002CW specifies 20 µA at 200 V, and STTH6002CW specifies 30 µA at 200 V. Lower reverse leakage current in the substitute parts may provide improved performance in high-impedance circuit applications.

Q: Do all parts meet RoHS and REACH compliance requirements?

A: All three parts are ROHS3 Compliant and REACH Unaffected, satisfying environmental and regulatory requirements for industrial and commercial applications.
