Key Parameters

Substitute Part Grouping Explanation

Substitution of the B180BE-13 is determined by equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 80 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Voltage - Forward (Vf) (Max) @ If: 790 mV or lower @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Technology: Schottky

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: DO-214AA, SMB
• Operating Temperature Range: Must encompass or exceed -55°C to 150°C

Compliance Criteria:

• RoHS3 Compliance required

The substitute part B180B-13-F meets all electrical and mechanical equivalence criteria. Variations in reverse leakage current, capacitance, and operating temperature range are within acceptable tolerance for functional substitution while maintaining the same base product family (B180 series) and package form factor.

Engineering Selection Recommendations

Primary Substitute: B180B-13-F

The B180B-13-F is the direct functional equivalent for the obsolete B180BE-13. Selection of this substitute is based on the following engineering factors:

Product Status Alignment: The B180B-13-F maintains active production status, ensuring long-term supply chain availability and eliminating obsolescence risk associated with the B180BE-13.

Electrical Equivalence: All critical electrical parameters—reverse voltage rating (80 V), average rectified current (1 A), forward voltage drop (790 mV @ 1 A), and recovery speed (Fast Recovery ≤ 500ns)—are identical between the main part and substitute. These parameters define the functional performance envelope for rectification applications.

Mechanical Compatibility: Both parts utilize identical Surface Mount packaging (DO-214AA, SMB), ensuring direct PCB footprint compatibility without layout modifications.

Compliance Certification: Both parts maintain ROHS3 compliance, satisfying regulatory requirements for restricted substance management.

Secondary Characteristics: The B180B-13-F exhibits higher reverse leakage current (500 µA versus 200 µA @ 80 V) and higher junction capacitance (80 pF versus 27 pF @ 4V, 1MHz). These variations remain within acceptable operational tolerances for standard rectification applications. The substitute also provides an extended operating temperature range (-65°C to 150°C versus -55°C to 150°C), offering improved performance margin in low-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can B180B-13-F be used as a direct replacement for B180BE-13 in existing designs?

A: Yes. The B180B-13-F is electrically and mechanically equivalent to the B180BE-13 across all critical parameters: reverse voltage (80 V), average rectified current (1 A), forward voltage drop (790 mV @ 1 A), recovery speed, and package form factor (DO-214AA, SMB). No circuit modifications are required.

Q: What is the difference in reverse leakage current between these parts?

A: The B180BE-13 specifies 200 µA reverse leakage at 80 V, while the B180B-13-F specifies 500 µA at the same conditions. This difference does not affect functional substitution in standard rectification applications where reverse leakage is not a critical design parameter.

Q: Why does the B180B-13-F have higher capacitance?

A: The B180B-13-F exhibits 80 pF capacitance at 4V, 1MHz compared to 27 pF for the B180BE-13. This variation is inherent to manufacturing process differences within the same product family. For most rectification applications, this capacitance difference does not impact circuit performance.

Q: Are the operating temperature ranges compatible?

A: The B180BE-13 operates from -55°C to 150°C junction temperature, while the B180B-13-F operates from -65°C to 150°C. The substitute provides a wider low-temperature operating range, making it suitable for all applications within the original part's temperature specification.

Q: What packaging difference exists between these parts?

A: The B180BE-13 is supplied in bulk packaging, while the B180B-13-F is supplied in Tape & Reel (TR) format. Both use identical DO-214AA, SMB package geometry. The packaging format difference affects handling and assembly processes but does not alter electrical or mechanical compatibility.

Q: Is the B180B-13-F RoHS compliant?

A: Yes. The B180B-13-F is ROHS3 compliant, matching the compliance status of the B180BE-13. Both parts satisfy regulatory requirements for restricted substance management.

Q: Why is the B180BE-13 classified as obsolete?

A: The B180BE-13 has been discontinued from active production by Diodes Incorporated. The B180B-13-F represents the active production equivalent within the same B180 product family, ensuring continued availability and supply chain support.
