Key Parameters

Substitute Part Grouping Explanation

Substitution of the UG2DHA0G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io): 2 A minimum
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 2 A maximum
• Current - Reverse Leakage @ Vr: 5 µA @ 200 V maximum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Equivalence Criteria:

• Package / Case: DO-204AC (DO-15) Axial
• Mounting Type: Through Hole
• Operating Temperature - Junction: -55°C to 150°C minimum

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Product Status: Active

All substitute parts listed maintain these parameters within the specified tolerances. Reverse recovery time (trr) and capacitance values may vary within the fast recovery classification without affecting functional substitution.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. The UG2DHA0G, SF24G A0G, SF24G, and UG2D-E3/73 are electrically and mechanically equivalent within the fast recovery diode classification for 200 V, 2 A applications.

Manufacturer Considerations:

• UG2DHA0G and SF24G variants are supplied by Taiwan Semiconductor Corporation
• UG2D-E3/73 is supplied by Vishay General Semiconductor - Diodes Division

Reverse Recovery Time Variation:

• UG2DHA0G and UG2D-E3/73 specify 25 ns trr
• SF24G A0G and SF24G specify 35 ns trr

Both trr values fall within the fast recovery classification (≤ 500ns, > 200mA) and maintain functional equivalence. Selection between these groups depends on application-specific switching speed requirements and supplier availability.

Packaging Availability:

• SF24G A0G and SF24G are supplied in Cut Tape (CT) packaging
• UG2DHA0G and UG2D-E3/73 packaging details are specified per supplier device package DO-204AC (DO-15)

Frequently Asked Questions (FAQ)

Q: Can SF24G A0G or SF24G be used as direct replacements for UG2DHA0G?

A: Yes. SF24G A0G and SF24G maintain electrical equivalence across all critical parameters: 200 V reverse voltage, 2 A average rectified current, 950 mV forward voltage at 2 A, 5 µA reverse leakage, and fast recovery speed classification. Both are packaged in DO-204AC (DO-15) through-hole axial format with identical operating temperature range (-55°C to 150°C) and ROHS3 compliance.

Q: What is the difference between UG2DHA0G and UG2D-E3/73?

A: Both parts are electrically equivalent with identical reverse recovery time (25 ns), reverse voltage (200 V), current rating (2 A), and forward voltage (950 mV @ 2 A). The primary difference is manufacturer: UG2DHA0G is Taiwan Semiconductor Corporation, while UG2D-E3/73 is Vishay General Semiconductor - Diodes Division. Both maintain DO-204AC (DO-15) through-hole axial packaging and ROHS3 compliance.

Q: Why do SF24G variants specify 35 ns reverse recovery time while UG2DHA0G specifies 25 ns?

A: Both reverse recovery times fall within the fast recovery diode classification (≤ 500ns, > 200mA). The 10 ns difference does not affect functional substitution for general-purpose rectification applications. Selection between these variants depends on application-specific switching speed requirements and supplier availability.

Q: Are all substitute parts AEC-Q101 qualified?

A: AEC-Q101 qualification is specified for UG2DHA0G. Qualification status for substitute parts SF24G A0G, SF24G, and UG2D-E3/73 is not provided in the available technical data. Verification of automotive qualification requirements should be confirmed with the respective manufacturer if AEC-Q101 compliance is mandatory for the application.

Q: Can these diodes be used in automotive applications?

A: UG2DHA0G carries AEC-Q101 automotive qualification. Substitute parts should be evaluated for automotive qualification status independently. All parts maintain ROHS3 compliance and operating temperature range (-55°C to 150°C) suitable for automotive thermal environments.

Q: What packaging formats are available for these substitute parts?

A: All substitute parts are supplied in DO-204AC (DO-15) through-hole axial package format. SF24G A0G and SF24G are supplied in Cut Tape (CT) packaging configuration. UG2DHA0G is available with 919 pieces in stock; SF24G A0G has 1025 pieces; SF24G has 1220 pieces; UG2D-E3/73 has 1980 pieces in stock.
