DBL208G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBL208G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 1.2 kV peak reverse voltage and 2 A average rectified current. This component is designed for through-hole mounting in 4-DIP package configuration and operates across the temperature range of -55°C to 150°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Bridge rectifiers serve as essential components in AC-to-DC conversion circuits. Identifying equivalent and substitute parts is necessary when managing inventory constraints, addressing supply chain disruptions, or selecting components with enhanced qualification levels for specific application requirements.

Substitute Part Grouping Explanation

Substitution of the DBL208G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for:

• Voltage rating (1.2 kV peak reverse voltage)
• Current capacity (2 A average rectified current)
• Forward voltage characteristics (1.3 V @ 2 A)
• Reverse leakage current (2 µA @ 1200 V)
• Operating temperature range (-55°C ~ 150°C)
• Diode type (Single Phase)
• Technology classification (Standard)
• Physical package (4-DIP, 0.300" / 7.62mm)
• Compliance certifications (ROHS3, REACH Unaffected)

The DBL208GH meets all these criteria and qualifies as a parametric equivalent. The substitute differs only in its automotive-grade qualification (AEC-Q101) and enhanced reliability classification, which represent additional certifications rather than deviations from the base electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The DBL208GH serves as a direct parametric equivalent to the DBL208G for applications requiring identical electrical and mechanical performance. Both parts maintain Active product status and full ROHS3 compliance.

Selection between these parts depends on application requirements:

DBL208G is appropriate for standard industrial applications where automotive qualification is not required. This part offers established availability with 1037 pieces in current inventory.

DBL208GH is appropriate for automotive applications or systems requiring AEC-Q101 qualification. This part carries automotive-grade designation and enhanced reliability certification. Current inventory availability is 5924 pieces.

Both parts are functionally interchangeable within circuits designed for 1.2 kV, 2 A single-phase bridge rectification. The choice between them is determined by application classification and qualification requirements rather than electrical performance differences.
