Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDBJSC51200-G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) Maximum: 1200 V
• Current - Average Rectified (Io): 5 A
• Voltage - Forward (Vf) Maximum @ If: 1.7 V @ 5 A
• Reverse Recovery Time (trr): 0 ns
• Technology: SiC (Silicon Carbide) Schottky
• Mounting Type: Through Hole
• Package / Case: TO-220-2
• Operating Temperature - Junction: -55°C to 175°C

Allowable Parameter Variations:

• Current - Reverse Leakage @ Vr: Variation permitted within device specifications
• Capacitance @ Vr, F: Variation permitted within device specifications
• Supplier Device Package designation: Variation permitted (TO220AC, TO-220AC equivalent to TO-220-2)

Two substitute parts meet these criteria: DSC05120 (Diodes Incorporated) and PCDP05120G1_T0_00001 (Panjit International Inc.). Both are active products with full RoHS3 compliance and identical core electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

DSC05120 (Diodes Incorporated): This substitute is an active product with full RoHS3 compliance and REACH Unaffected status. It maintains identical voltage, current, and forward voltage specifications. The reverse leakage current is 190 µA at 1200 V, which is within acceptable variation for this device category. Capacitance is 310 pF at 100 mV, 1 MHz. Current inventory availability is 884 pieces. This part is suitable for direct substitution in applications where the CDBJSC51200-G is specified.

PCDP05120G1_T0_00001 (Panjit International Inc.): This substitute is an active product with full RoHS3 compliance and REACH Unaffected status. It maintains identical voltage, current, and forward voltage specifications. The reverse leakage current is 50 µA at 1200 V, representing the lowest leakage among the three options. Capacitance is 252 pF at 1 V, 1 MHz. Current inventory availability is 2697 pieces, the highest among all options. This part is suitable for direct substitution in applications where the CDBJSC51200-G is specified.

Both substitute parts are functionally equivalent and interchangeable based on the provided electrical and mechanical parameters. Selection between them may be based on inventory availability, supplier preference, or specific application requirements related to reverse leakage or capacitance characteristics.

Frequently Asked Questions (FAQ)

Q: Can DSC05120 and PCDP05120G1_T0_00001 be used interchangeably with CDBJSC51200-G?

A: Yes. Both parts meet all mandatory electrical and mechanical parameters: 1200 V reverse voltage, 5 A average rectified current, 1.7 V forward voltage at 5 A, 0 ns reverse recovery time, through-hole mounting, TO-220-2 package, and -55°C to 175°C operating temperature range. Both are RoHS3 compliant and use SiC Schottky technology.

Q: What are the differences between the two substitute parts?

A: The primary differences are reverse leakage current and capacitance. PCDP05120G1_T0_00001 has lower reverse leakage (50 µA vs. 190 µA) and lower capacitance (252 pF vs. 310 pF). Both differences are within acceptable device variation and do not affect functional equivalence for standard applications.

Q: Why is CDBJSC51200-G marked as obsolete?

A: The CDBJSC51200-G is classified as obsolete by the manufacturer. DSC05120 and PCDP05120G1_T0_00001 are active products from alternative manufacturers and provide equivalent functionality for ongoing design support and production requirements.

Q: Are there any package differences between these parts?

A: All three parts use the TO-220-2 package for through-hole mounting. The supplier device package designations vary (TO220AC Type WX for DSC05120, TO-220AC for PCDP05120G1_T0_00001), but these are equivalent package formats compatible with standard TO-220-2 footprints.

Q: What compliance certifications apply to these parts?

A: All three parts are RoHS3 compliant. DSC05120 and PCDP05120G1_T0_00001 are both REACH Unaffected. All parts carry EAR99 ECCN classification and HTSUS code 8541.10.0080.

Q: Which substitute part should be selected for new designs?

A: Both DSC05120 and PCDP05120G1_T0_00001 are suitable for new designs. PCDP05120G1_T0_00001 offers higher inventory availability (2697 pieces) and lower reverse leakage characteristics. DSC05120 is available from Diodes Incorporated with 884 pieces in stock. Selection should be based on supplier availability, lead time requirements, and specific application performance criteria.
