B170AE-13 Equivalent & Substitute Parts

Part Overview

The B170AE-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 70V DC reverse voltage and 1A average rectified current in a surface mount SMA package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The B170AE-13 remains available in inventory but is no longer in active production status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the B170AE-13 is determined by equivalence in the following critical parameters:

Electrical Equivalence Requirements:

• 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 Equivalence Requirements:

• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount

The B170-13-F qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both parts share the same base product number (B170) and are manufactured by Diodes Incorporated. The primary distinction is product status: B170AE-13 is obsolete while B170-13-F is active production.

Engineering Selection Recommendations

For New Designs: The B170-13-F is the appropriate selection for new product development. This part is in active production status with ROHS3 compliance and improved REACH status (unaffected versus affected). The extended operating temperature range (-65°C to 150°C versus -55°C to 150°C) provides additional design margin for low-temperature applications.

For Existing Inventory Management: The B170AE-13 remains functionally equivalent for applications where the specified electrical and mechanical parameters are sufficient. However, transition to B170-13-F is recommended for long-term supply chain stability given the obsolete status of B170AE-13.

Parameter Considerations: The B170-13-F exhibits higher reverse leakage current (500 µA versus 200 µA at 70V) and higher junction capacitance (80 pF versus 27 pF at 4V, 1MHz). These differences are within the Schottky diode technology envelope and do not affect functional equivalence for standard rectification applications. Applications with stringent leakage or capacitance requirements must evaluate these differences against specific circuit performance criteria.

Packaging Transition: B170-13-F is supplied in Tape & Reel format, standard for high-volume manufacturing. The B170AE-13 bulk packaging may require process adjustment during transition to automated assembly.

Frequently Asked Questions (FAQ)

Q: Can B170-13-F directly replace B170AE-13 in existing designs?

A: Yes. Both parts meet identical electrical specifications for voltage rating (70V), current rating (1A), forward voltage (790 mV @ 1A), and switching speed (Fast Recovery ≤ 500ns). Package and mounting type are identical (DO-214AC, SMA, surface mount). The parts are functionally interchangeable for standard rectification applications.

Q: What are the differences between B170AE-13 and B170-13-F?

A: The primary differences are: (1) Product Status—B170AE-13 is obsolete while B170-13-F is active production; (2) Operating Temperature Range—B170-13-F extends to -65°C versus -55°C minimum; (3) Reverse Leakage—B170-13-F is 500 µA versus 200 µA at 70V; (4) Junction Capacitance—B170-13-F is 80 pF versus 27 pF at 4V, 1MHz; (5) Packaging—B170-13-F is supplied in Tape & Reel format; (6) REACH Status—B170-13-F is unaffected versus affected.

Q: Are there applications where B170AE-13 and B170-13-F are not interchangeable?

A: Applications requiring reverse leakage current below 500 µA or junction capacitance below 80 pF must evaluate the parameter differences. The B170AE-13 provides lower leakage and capacitance. For standard rectification, power supply, and switching applications, the differences are not functionally significant.

Q: What is the impact of the extended temperature range in B170-13-F?

A: The B170-13-F operating range of -65°C to 150°C provides 10°C additional margin at the lower temperature limit compared to B170AE-13 (-55°C to 150°C). This is beneficial for applications in cold environments or where thermal cycling stress is a design consideration.

Q: How does the Tape & Reel packaging of B170-13-F affect component selection?

A: Tape & Reel packaging is standard for automated surface mount assembly and high-volume production. If existing processes require bulk packaging, packaging format conversion may be necessary. Functionally, the component performance is identical regardless of packaging format.

Q: Are both parts RoHS and REACH compliant?

A: Both parts are ROHS3 compliant. B170-13-F has improved REACH status (unaffected) compared to B170AE-13 (affected). For applications subject to REACH regulations, B170-13-F is the preferred selection.
