Key Parameters

Substitute Part Grouping Explanation

Substitution of the B320CE-13 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): 20 V minimum
• Current - Average Rectified (Io): 3 A minimum
• Voltage - Forward (Vf) (Max) @ If: 500 mV or lower at 3 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Technology: Schottky diode

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: DO-214AB (SMC) or equivalent footprint (DO-214AC/SMA with design verification)
• Operating Temperature - Junction: -55°C minimum to 125°C or higher

Compliance Criteria:

• RoHS3 Compliant
• REACH Status: Unaffected or Affected (both acceptable for substitution)

Substitute parts are grouped into two categories: Direct Manufacturer Equivalents (same manufacturer, active product status) and Parametric Equivalents (alternative manufacturers, matching or exceeding electrical specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Equivalent - Preferred for Standard Applications:

The B320-13-F is the primary direct substitute for the B320CE-13. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications (20 V, 3 A, 500 mV forward voltage, fast recovery). The B320-13-F is in Active product status with 32,400 units in stock, ensuring long-term availability. The primary difference is operating temperature range: B320-13-F operates to 125°C versus B320CE-13's 150°C. For applications requiring the full 150°C junction temperature capability, this part is suitable only if the design thermal profile does not exceed 125°C. The B320-13-F is supplied in Tape & Reel packaging with MSL 1 (Unlimited) moisture sensitivity rating.

Automotive-Grade Equivalent - For Automotive and High-Reliability Applications:

The B320Q-13-F and Vishay SS32HE3_B/H and SS32HE3_B/I parts are automotive-grade Schottky diodes qualified to AEC-Q101 standard. These parts maintain the same 20 V, 3 A electrical specifications and support the full -55°C to 150°C operating temperature range. The B320Q-13-F is manufactured by Diodes Incorporated (9,400 units in stock), while the Vishay parts (SS32HE3_B/H with 680 units and SS32HE3_B/I with 920 units) provide alternative sourcing. All three automotive-grade options are suitable for applications requiring automotive qualification or enhanced reliability screening.

Alternative Manufacturer Equivalent - For Cost Optimization:

The MDD SS32 is a parametric equivalent offering the same 20 V, 3 A Schottky diode performance. The SS32 uses a DO-214AC (SMA) package instead of DO-214AB (SMC), requiring PCB footprint verification before substitution. The SS32 operates to 125°C maximum junction temperature and has higher capacitance (500 pF versus 140-200 pF), which may affect high-frequency circuit performance. The SS32 is available in high quantity (19,566 units in stock) and provides cost optimization for non-automotive applications where package size differences are acceptable.

Selection Criteria Summary:

• Standard replacement with identical package: B320-13-F (verify 125°C temperature limit)
• Automotive applications or 150°C requirement: B320Q-13-F, SS32HE3_B/H, or SS32HE3_B/I
• Cost optimization with package change: SS32 (requires PCB redesign verification)

Frequently Asked Questions (FAQ)

Q: Can B320-13-F directly replace B320CE-13 without PCB modifications?

A: Yes. The B320-13-F is pin-compatible and uses the same DO-214AB (SMC) package footprint as the B320CE-13. No PCB layout changes are required. However, verify that your application's maximum junction temperature does not exceed 125°C, as the B320-13-F is rated to 125°C versus the B320CE-13's 150°C.

Q: What is the difference between B320Q-13-F and B320-13-F?

A: Both parts are manufactured by Diodes Incorporated with identical electrical specifications. The B320Q-13-F is automotive-grade with AEC-Q101 qualification and supports the full -55°C to 150°C operating temperature range. The B320-13-F is standard-grade and operates to 125°C. Select B320Q-13-F for automotive applications or designs requiring 150°C junction temperature capability.

Q: Are Vishay SS32HE3_B/H and SS32HE3_B/I interchangeable?

A: Yes. Both Vishay parts are automotive-grade Schottky diodes with identical electrical specifications, package (DO-214AB/SMC), and operating temperature range (-55°C to 150°C). Both are AEC-Q101 qualified. The part number suffix (_B/H versus _B/I) indicates internal manufacturing or qualification variants but does not affect electrical or mechanical compatibility.

Q: Can SS32 replace B320CE-13 in my design?

A: The SS32 is electrically compatible (20 V, 3 A, fast recovery Schottky) but uses a different package: DO-214AC (SMA) instead of DO-214AB (SMC). The SMA package is physically smaller than SMC. Substitution requires PCB footprint redesign and verification. Additionally, the SS32 operates to 125°C maximum and has higher capacitance (500 pF), which may affect circuit performance at high frequencies. Evaluate these factors before selecting SS32.

Q: What does "Fast Recovery ≤ 500ns, > 200mA (Io)" mean?

A: This specification indicates the diode's reverse recovery time is 500 nanoseconds or less when switching from forward conduction at currents greater than 200 mA. Fast recovery characteristics minimize switching losses and are essential for high-frequency rectification applications. All substitute parts listed meet this specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (B320-13-F, B320Q-13-F, SS32HE3_B/H, SS32HE3_B/I, and SS32) are ROHS3 compliant, matching the B320CE-13's environmental compliance status.

Q: What is the significance of "Tape & Reel (TR)" packaging?

A: Tape & Reel packaging indicates the parts are supplied on continuous carrier tape wound on reels, suitable for automated assembly equipment. This packaging format is standard for high-volume production. The B320-13-F, B320Q-13-F, and Vishay parts are supplied in Tape & Reel format, enabling efficient pick-and-place assembly. The original B320CE-13 and MDD SS32 do not specify packaging format in the provided data.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL (Moisture Sensitivity Level) 1 (Unlimited) indicates the component has minimal moisture absorption risk and does not require special moisture-control handling during storage or assembly. Parts with MSL 1 can be stored at standard ambient conditions without desiccant packaging or baking procedures before reflow soldering.

Q: Why is the B320CE-13 marked as Obsolete?

A: The B320CE-13 is no longer in active production by Diodes Incorporated. Existing inventory (703 units) is available, but long-term procurement is not guaranteed. Transitioning to active-status alternatives (B320-13-F, B320Q-13-F, or Vishay equivalents) ensures design continuity and future availability.

Q: Can I use multiple substitute parts interchangeably in the same design?

A: B320-13-F, B320Q-13-F, SS32HE3_B/H, and SS32HE3_B/I are interchangeable in the same DO-214AB (SMC) footprint. However, do not mix parts with different operating temperature ratings in the same circuit unless thermal analysis confirms all parts operate within their respective limits. The SS32 (SMA package) requires separate PCB footprint design and is not interchangeable with SMC-packaged parts.
