Key Parameters

Substitute Part Grouping Explanation

Substitution of the TT3M bridge rectifier is determined by electrical and mechanical parameter equivalence. The following criteria establish functional interchangeability:

Electrical Parameters:

• Voltage - Peak Reverse (Max): 1 kV
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 1.5 A
• Current - Reverse Leakage @ Vr: 5 µA @ 1000 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Mechanical Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Supplier Device Package: TT

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitute components must match all electrical specifications, maintain identical mechanical form factor and mounting characteristics, and satisfy regulatory compliance requirements. The TT3M_HF variant meets all substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The TT3M_HF is the manufacturer-recommended substitute for the obsolete TT3M bridge rectifier. Both components are manufactured by Diodes Incorporated and share identical electrical specifications, mechanical packaging, and regulatory compliance certifications.

Selection Basis:

The TT3M_HF maintains full electrical and mechanical compatibility with the TT3M across all specified parameters: 1 kV peak reverse voltage, 3 A average rectified current, 1 V forward voltage at 1.5 A, and -55°C to 150°C operating temperature range. Both components utilize the 4-SMD Gull Wing package configuration with TT supplier device package designation.

Regulatory compliance is equivalent for both parts, with ROHS3 compliance and REACH Unaffected status. The primary distinction is product status: the TT3M_HF is classified as Active, ensuring ongoing availability and supply chain continuity, whereas the TT3M is Obsolete.

For new designs and procurement of replacement components, the TT3M_HF is the appropriate selection. Direct substitution is supported without circuit modification or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the TT3M_HF be used as a direct replacement for the TT3M in existing designs?
