Electrical Specifications:

• Voltage - Peak Reverse (Max): 1.4 kV
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 1.5 A
• Current - Reverse Leakage @ Vr: 2 µA @ 1400 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Mechanical Specifications:

• Mounting Type: Through Hole
• Package / Case: 4-DIP (0.300", 7.62mm)
• Diode Type: Single Phase
• Technology: Standard

Compliance & Environmental:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must match all electrical and mechanical parameters without exception. Compliance certifications must be maintained or exceed the original specification.

Parameter Comparison

Engineering Selection Recommendations

The DBL159GH is a direct parametric equivalent to the DBL159G, with identical electrical and mechanical specifications across all critical performance parameters. Both components maintain Active product status and ROHS3 compliance.

The DBL159GH incorporates Automotive grade qualification and AEC-Q101 certification, which represents an enhancement over the standard-grade DBL159G. This additional qualification does not restrict its use in non-automotive applications and provides expanded reliability documentation for applications requiring automotive-level component traceability.

Selection between DBL159G and DBL159GH should be based on:

1. Inventory Availability: DBL159GH maintains higher stock levels (6014 pieces) compared to DBL159G (1133 pieces)
2. Compliance Requirements: Applications requiring automotive-grade components or AEC-Q101 certification should specify DBL159GH
3. Circuit Performance: No performance differentiation exists between the two parts for standard bridge rectification applications

Both parts are suitable for direct substitution in through-hole PCB designs requiring 1.4 kV, 1.5 A single-phase bridge rectification.

Frequently Asked Questions (FAQ)

Q: Can DBL159GH replace DBL159G in existing circuit designs?

A: Yes. The DBL159GH is a direct parametric equivalent with identical electrical ratings (1.4 kV peak reverse voltage, 1.5 A average rectified current, 1.25 V forward voltage drop), identical operating temperature range (-55°C to 150°C), and identical 4-DIP through-hole package dimensions. No circuit modifications are required.

Q: What is the difference between DBL159G and DBL159GH?

A: Both parts share identical electrical and mechanical specifications. The DBL159GH includes Automotive grade designation and AEC-Q101 qualification, which provides additional reliability documentation and traceability for automotive applications. This does not affect performance in standard industrial applications.

Q: Are both parts RoHS compliant?

A: Yes. Both DBL159G and DBL159GH are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the package compatibility between these parts?

A: Both parts use identical 4-DIP (0.300", 7.62mm) through-hole packaging. PCB footprints, lead spacing, and mounting hole requirements are identical. No PCB redesign is necessary when substituting between these parts.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For automotive or safety-critical applications requiring AEC-Q101 certification, specify DBL159GH. For standard industrial applications, either part is suitable. DBL159GH offers higher inventory availability (6014 pieces versus 1133 pieces).

Q: Are there any temperature or voltage derating considerations?

A: Both parts operate identically across the -55°C to 150°C junction temperature range with 1.4 kV peak reverse voltage rating and 1.5 A average rectified current. No derating differences exist between the two parts.
