B80C1500B Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The B80C1500B is a single-phase bridge rectifier manufactured by Diotec Semiconductor, designed for standard rectification applications requiring 160 V peak reverse voltage and 1.8 A average rectified current. This component is housed in a 4-ESIP through-hole package with physical dimensions of 19×10×3.5 mm. The part maintains Active product status with 1373 pieces currently in stock as new original inventory.

Bridge rectifiers serve as essential components in AC-to-DC conversion circuits. Substitute parts become necessary when original inventory is unavailable, when supply chain constraints occur, or when design flexibility permits component standardization across manufacturing facilities.

• Operating Temperature Range: -50°C to 150°C or wider

Mechanical Parameters (Critical):

• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package / Case: 4-ESIP or equivalent 4-pin SIP configuration
• Physical compatibility with 19×10×3.5 mm footprint or PCB layout accommodation

Product Status:

• Active product status preferred for long-term supply assurance

No parametric equivalents have been provided in the input data. Substitute parts must be identified from component suppliers using the above criteria as selection filters.

Engineering Selection Recommendations

Selection of substitute parts for the B80C1500B must be based on the following engineering criteria:

Product Status Consideration: The B80C1500B maintains Active product status, indicating ongoing manufacturer support and availability. Substitute parts should preferably maintain Active status to ensure long-term supply chain stability and consistent quality control.

Compliance and Certification: The B80C1500B carries ECCN classification EAR99 and HTSUS code 8541.10.0080. Substitute parts must maintain equivalent or compatible compliance classifications for applications subject to export control or tariff regulations. RoHS Status is listed as Not Applicable for this component; substitute parts should maintain equivalent RoHS applicability status.

Electrical Performance Matching: Substitute parts must meet or exceed all specified electrical parameters. Parts with higher voltage ratings (>160 V) or higher current ratings (>1.8 A) are acceptable. Parts with lower forward voltage (Vf < 1.1 V @ 2 A) or lower reverse leakage (< 5 µA @ 160 V) are acceptable and may provide improved efficiency or reduced heat dissipation.

Thermal and Environmental Compatibility: The operating temperature range of -50°C to 150°C (TJ) must be maintained or exceeded in substitute parts. Applications operating at temperature extremes require verification that substitute parts support the full specified range.

Package and Mounting Compatibility: Through-hole mounting type and 4-ESIP package configuration are mandatory for direct PCB substitution without layout modification. Physical dimensions of 19×10×3.5 mm should be verified for mechanical clearance in existing designs.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the B80C1500B?

A: A valid substitute must be a single-phase standard bridge rectifier with through-hole 4-ESIP mounting, peak reverse voltage of 160 V or higher, average rectified current of 1.8 A or higher, forward voltage of 1.1 V or less @ 2 A, reverse leakage of 5 µA or less @ 160 V, and operating temperature range of -50°C to 150°C or wider.

Q: Can I use a bridge rectifier with higher voltage or current ratings?

A: Yes. Bridge rectifiers with higher voltage ratings (exceeding 160 V) or higher current ratings (exceeding 1.8 A) are electrically compatible substitutes. Higher ratings provide design margin and may improve reliability in applications with voltage or current transients.

Q: Are there package alternatives to 4-ESIP?

A: The 4-ESIP package is the specified configuration for the B80C1500B. Direct substitutes must use the same 4-ESIP or equivalent 4-SIP package to maintain PCB compatibility without layout redesign. Other package types (such as surface-mount or different pin configurations) require circuit board modification.

Q: What is the significance of the forward voltage specification?

A: Forward voltage (Vf) of 1.1 V @ 2 A determines the voltage drop across the bridge rectifier during conduction. Lower forward voltage reduces power dissipation and heat generation. Substitute parts with Vf ≤ 1.1 V @ 2 A maintain or improve thermal performance.

Q: How does reverse leakage current affect circuit performance?

A: Reverse leakage current of 5 µA @ 160 V represents the small current flowing through the rectifier when reverse-biased. Lower leakage improves circuit efficiency and reduces standby power consumption. Substitute parts with leakage ≤ 5 µA @ 160 V maintain equivalent or superior performance.

Q: Is the Active product status important for long-term supply?

A: Active product status indicates the manufacturer continues production and provides technical support. For applications requiring long-term component availability, substitute parts with Active status are preferred over obsolete or end-of-life components.

Q: What compliance considerations apply to substitute selection?

A: The B80C1500B carries ECCN EAR99 classification and HTSUS code 8541.10.0080. Substitute parts should maintain equivalent compliance classifications. RoHS Status is Not Applicable for this component; substitute parts should maintain equivalent RoHS applicability to avoid compliance conflicts in regulated markets.

Q: Can I substitute a three-phase bridge rectifier for this single-phase part?

A: No. The B80C1500B is specified as single-phase. Three-phase bridge rectifiers have different electrical characteristics and pin configurations. Only single-phase bridge rectifiers are valid substitutes.
