DSK10C-BT General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The DSK10C-BT is a general purpose rectifier diode manufactured by onsemi, rated for 200 V DC reverse voltage and 1 A average rectified current in an axial through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design requirements and production continuity. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating available packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DSK10C-BT are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Voltage - Forward (Vf) (Max) @ If: 1.1 V or lower @ 1 A
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 10 µA or lower @ 200 V
• Operating Temperature - Junction: 150°C or higher

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: Axial configuration

The substitute parts identified—1N4003G and MPG06D-E3/54—meet or exceed all specified electrical parameters and maintain through-hole axial mounting compatibility. Both parts are active products with current manufacturing status and full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

1N4003G (Taiwan Semiconductor Corporation)

The 1N4003G is an active product offering superior reverse leakage performance (5 µA versus 10 µA) and lower forward voltage drop (1 V versus 1.1 V). This part is ROHS3 compliant and features an extended operating temperature range (-55°C to 150°C). The DO-204AL (DO-41) package is a standard axial configuration with widespread availability (27,889 units in stock). Selection of this part is appropriate for applications requiring enhanced electrical performance and regulatory compliance.

MPG06D-E3/54 (Vishay General Semiconductor - Diodes Division)

The MPG06D-E3/54 maintains electrical equivalence with the original DSK10C-BT, including identical forward voltage specification (1.1 V @ 1 A) and improved reverse leakage (5 µA). This part is ROHS3 compliant with an extended operating temperature range (-55°C to 150°C). The MPG06 package is an axial through-hole configuration with documented reverse recovery time (600 ns). This part is supplied in tape and reel packaging and maintains 3,373 units in stock. Selection of this part is appropriate for applications requiring direct electrical equivalence with enhanced compliance certifications.

Both substitute parts satisfy all electrical and mechanical requirements for the obsolete DSK10C-BT and are suitable for direct replacement in through-hole circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 1N4003G and MPG06D-E3/54 be used interchangeably with the DSK10C-BT?

A: Both parts meet the electrical specifications (200 V reverse voltage, 1 A average rectified current, standard recovery speed) and mounting requirements (through-hole axial). Physical package dimensions may differ between R-1, DO-41, and MPG06 configurations; verify PCB footprint compatibility before implementation.

Q: What is the difference in forward voltage between the substitute parts?

A: The 1N4003G specifies 1 V maximum forward voltage at 1 A, while the MPG06D-E3/54 specifies 1.1 V maximum at 1 A. The DSK10C-BT specifies 1.1 V maximum. The 1N4003G offers improved performance in this parameter.

Q: Are both substitute parts compliant with current regulatory standards?

A: Yes. Both the 1N4003G and MPG06D-E3/54 are ROHS3 compliant and REACH unaffected. The DSK10C-BT product status is obsolete; the substitute parts are active products with current manufacturing support.

Q: What is the reverse leakage current difference?

A: The DSK10C-BT specifies 10 µA maximum reverse leakage at 200 V. Both substitute parts specify 5 µA maximum at 200 V, representing improved leakage performance.

Q: How do the operating temperature ranges compare?

A: The DSK10C-BT specifies a maximum junction temperature of 150°C. Both substitute parts specify an operating range of -55°C to 150°C, providing extended low-temperature capability.

Q: What packaging considerations apply to these substitutes?

A: The DSK10C-BT uses R-1 axial packaging. The 1N4003G uses DO-204AL (DO-41) axial packaging. The MPG06D-E3/54 uses MPG06 axial packaging. All three are through-hole axial configurations; verify PCB hole spacing and lead diameter compatibility for your specific application.

Q: Which substitute part has the highest inventory availability?

A: The 1N4003G has 27,889 units in stock, compared to 3,373 units for the MPG06D-E3/54. The original DSK10C-BT has 845 units in stock but is obsolete.
