Substitute Part Grouping Explanation

Substitution of the B350CE-13 is determined by electrical and mechanical parameter equivalence within the Schottky diode rectifier category. The critical parameters governing substitution are:

Voltage Rating: 50 V DC reverse voltage (Vr) maximum
Current Rating: 3 A average rectified current (Io)
Package Type: DO-214AB, SMC surface mount configuration
Technology: Schottky rectifier diode
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

The B350-13-F qualifies as a direct substitute based on matching voltage, current, package, and technology specifications. Both parts share the same base product number (B350) and are manufactured by Diodes Incorporated. Differences in forward voltage, reverse leakage current, capacitance, and operating temperature range do not preclude substitution when the application requirements fall within the specified limits of the substitute part.

Engineering Selection Recommendations

The B350-13-F is the designated substitute for the obsolete B350CE-13. Both components are manufactured by Diodes Incorporated and share identical voltage and current ratings, package configuration, and Schottky technology classification. The B350-13-F maintains Active product status, ensuring long-term availability and supply chain continuity.

Both parts comply with ROHS3 standards and carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The B350-13-F is supplied in Tape & Reel (TR) packaging with Moisture Sensitivity Level (MSL) 1 (Unlimited), providing enhanced handling flexibility compared to the obsolete variant.

The B350-13-F exhibits higher forward voltage (700 mV versus 650 mV at 3 A), increased reverse leakage current (500 µA versus 100 µA at 50 V), and higher capacitance (200 pF versus 110 pF at 4V, 1MHz). The operating temperature range is reduced to -55°C to 125°C. These parameter variations must be evaluated against specific application requirements to confirm compatibility.

Frequently Asked Questions (FAQ)

Q: Can the B350-13-F directly replace the B350CE-13 in existing designs?

A: The B350-13-F matches the B350CE-13 in voltage rating (50 V), current rating (3 A), package type (DO-214AB, SMC), and Schottky technology. Direct substitution is permissible when application requirements accommodate the higher forward voltage (700 mV), increased reverse leakage current (500 µA), and reduced maximum junction temperature (125°C versus 150°C).

Q: What are the key electrical differences between these parts?

A: The B350-13-F exhibits 50 mV higher forward voltage drop at 3 A, 400 µA higher reverse leakage current at 50 V, and 90 pF higher capacitance at 4V, 1MHz. The maximum operating junction temperature is 25°C lower. These differences affect power dissipation, leakage characteristics, and high-temperature performance.

Q: Are both parts RoHS and REACH compliant?

A: Both parts are ROHS3 Compliant. The B350CE-13 is REACH Affected, while the B350-13-F is REACH Unaffected. Compliance requirements for specific applications must be verified against applicable regulations.

Q: What packaging formats are available?

A: The B350CE-13 is supplied in standard packaging format. The B350-13-F is supplied in Tape & Reel (TR) format with Moisture Sensitivity Level (MSL) 1 (Unlimited), suitable for automated assembly processes.

Q: Why is the B350CE-13 classified as Obsolete?

A: The B350CE-13 has been discontinued from active production by Diodes Incorporated. The B350-13-F represents the current active equivalent within the B350 product family.

Q: Are there any thermal considerations when substituting these parts?

A: The B350-13-F has a maximum junction temperature of 125°C compared to 150°C for the B350CE-13. Applications operating near the upper temperature limit of the original design must be re-evaluated to confirm the substitute part remains within acceptable thermal margins.
