Substitute Part Grouping Explanation

Substitution eligibility for the DFB2080 is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase
• Voltage - Peak Reverse (Max): 800 V
• Current - Average Rectified (Io): 20 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 20 A
• Current - Reverse Leakage @ Vr: 10 µA @ 800 V
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Two substitute parts meet these criteria: TS20P06G (Taiwan Semiconductor Corporation) and GBJ2008 (SMC Diode Solutions). Both maintain identical electrical specifications and compliance certifications. Package variations exist between TS-6P (DFB2080 and TS20P06G) and GBJ (GBJ2008), which may affect mechanical fit in existing PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

TS20P06G is the preferred substitute for DFB2080 applications. Both components use identical TS-6P packaging, ensuring direct mechanical and electrical compatibility without PCB layout modifications. TS20P06G maintains active product status with unlimited moisture sensitivity level (MSL 1), supporting long-term supply chain continuity.

GBJ2008 provides an alternative substitute with equivalent electrical performance. The GBJ package differs mechanically from TS-6P, requiring PCB footprint verification before implementation. GBJ2008 is also active and ROHS3 compliant. MSL 1 rating indicates suitability for standard storage and handling conditions.

Both substitutes are ROHS3 compliant and maintain the full operating temperature range of -55°C to 150°C (TJ), meeting industrial application requirements.

Frequently Asked Questions (FAQ)

Q: Can TS20P06G directly replace DFB2080 without PCB modifications?

A: Yes. Both components use the 4-SIP, TS-6P package, providing identical pin configuration and mechanical fit.

Q: What is the primary difference between TS20P06G and GBJ2008?

A: Package type. TS20P06G uses TS-6P; GBJ2008 uses GBJ. Electrical specifications are identical. Package selection depends on existing PCB footprint design.

Q: Are both substitutes suitable for new designs?

A: Yes. Both TS20P06G and GBJ2008 carry active product status, making them appropriate for new design implementations.

Q: Do the substitutes maintain the same operating temperature range?

A: Yes. All three parts operate across -55°C to 150°C (TJ), ensuring thermal compatibility in existing applications.

Q: What compliance certifications apply to these substitutes?

A: Both TS20P06G and GBJ2008 are ROHS3 compliant and carry EAR99 ECCN classification, matching the DFB2080 compliance profile.
