Key Parameters

Substitute Part Grouping Explanation

Substitution of the B170BE-13 is based on electrical and mechanical parameter equivalence within the Schottky rectifier diode category. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 70 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 790 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Technology: Schottky

Mechanical Parameters (Must Match):

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant

The substitute part B170B-13-F meets all electrical and mechanical requirements for direct substitution. Variations in secondary parameters such as reverse leakage current, capacitance, and operating temperature range do not preclude substitution when primary electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

The B170B-13-F is a direct electrical and mechanical substitute for the B170BE-13. Both components are manufactured by Diodes Incorporated and share identical core specifications for voltage rating, current capacity, forward voltage drop, and switching speed. Both are ROHS3 compliant and packaged in the DO-214AA SMB surface mount format.

The B170B-13-F offers the following advantages:

• Active Product Status: The substitute is in active production, ensuring long-term availability and supply chain stability compared to the obsolete B170BE-13.
• Extended Operating Temperature Range: The B170B-13-F supports operation from -65°C to 150°C, providing a 10°C lower minimum junction temperature compared to the B170BE-13 (-55°C to 150°C).
• Moisture Sensitivity Level (MSL) Rating: The B170B-13-F carries an MSL 1 (Unlimited) classification, indicating superior moisture resistance for storage and handling.
• Packaging Format: The B170B-13-F is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Secondary parameter variations (reverse leakage current and capacitance) do not affect functional substitution in standard rectification applications where the primary electrical specifications are met.

Frequently Asked Questions (FAQ)

Q: Can the B170B-13-F directly replace the B170BE-13 in existing designs?

A: Yes. The B170B-13-F meets all primary electrical specifications (70 V reverse voltage, 1 A average rectified current, 790 mV forward voltage drop) and mechanical requirements (DO-214AA SMB package, surface mount) of the B170BE-13. No circuit modifications are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The B170BE-13 is obsolete and no longer manufactured. The B170B-13-F is in active production, ensuring component availability for current and future procurement. Designs should transition to the B170B-13-F to avoid supply chain disruptions.

Q: Are there differences in reverse leakage current between these parts?

A: Yes. The B170BE-13 specifies 200 µA reverse leakage at 70 V, while the B170B-13-F specifies 500 µA at 70 V. This variation does not affect substitution in standard rectification circuits where reverse leakage is not a critical design parameter. Applications requiring specific leakage characteristics should be evaluated individually.

Q: What is the difference in capacitance between these parts?

A: The B170BE-13 has 27 pF capacitance at 4 V and 1 MHz, while the B170B-13-F has 80 pF at the same conditions. This variation does not preclude substitution in standard rectification applications. High-frequency or RF applications sensitive to junction capacitance should be evaluated for circuit impact.

Q: Does the extended operating temperature range of the B170B-13-F provide additional design margin?

A: Yes. The B170B-13-F supports operation from -65°C to 150°C compared to -55°C to 150°C for the B170BE-13. This 10°C extension at the lower temperature limit provides additional margin for applications operating in cold environments.

Q: What packaging format is the B170B-13-F supplied in?

A: The B170B-13-F is supplied in Tape & Reel (TR) format, optimized for automated surface mount assembly. The B170BE-13 packaging format is not specified in the provided data. Tape & Reel format is standard for high-volume production environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the B170BE-13 and B170B-13-F are ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.
