Substitute Part Grouping Explanation

The B250-13-F qualifies as a direct substitute for the B245BE-13 based on the following substitution criteria:

Matching Parameters:

Current - Average Rectified (Io): 2 A (identical)
Technology: Schottky (identical)
Package / Case: DO-214AA, SMB (identical)
Mounting Type: Surface Mount (identical)
Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io) (identical)

Allowable Deviations:

Voltage - DC Reverse (Vr) (Max): 50 V (higher than 45 V requirement; acceptable for backward compatibility)
Operating Temperature - Junction: -65°C ~ 150°C (wider range than -55°C ~ 150°C; acceptable)

The B250-13-F maintains the same current rating and package form factor while providing higher voltage capability and extended low-temperature operation. These characteristics permit direct substitution in applications designed for the B245BE-13.

Engineering Selection Recommendations

The B250-13-F is the designated substitute for the obsolete B245BE-13. Selection of the B250-13-F is supported by the following factors:

Product Status: The B245BE-13 is obsolete, while the B250-13-F maintains active manufacturing status with substantial inventory availability (18,186 pieces in stock versus 832 pieces for the obsolete part).

Compliance: Both parts maintain ROHS3 compliance. The B250-13-F is REACH unaffected, whereas the B245BE-13 is REACH affected. Both carry EAR99 ECCN classification.

Electrical Compatibility: The B250-13-F operates at a higher reverse voltage rating (50 V versus 45 V), which provides margin for applications designed around the B245BE-13 specifications. The identical current rating (2 A) and package form factor (DO-214AA, SMB) ensure mechanical and thermal compatibility.

Operational Considerations: The B250-13-F exhibits higher forward voltage drop (700 mV versus 500 mV at 2 A) and higher reverse leakage current (500 µA at 50 V versus 200 µA at 45 V). These differences must be evaluated within the context of specific circuit requirements, particularly in power dissipation and leakage-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the B250-13-F directly replace the B245BE-13 in existing designs?

A: Yes. The B250-13-F maintains identical current rating (2 A), identical package form factor (DO-214AA, SMB), and identical fast recovery speed characteristics. The higher voltage rating (50 V versus 45 V) provides backward compatibility for applications designed for 45 V operation.

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

A: The B250-13-F has a higher forward voltage drop (700 mV versus 500 mV at 2 A) and higher reverse leakage current (500 µA at 50 V versus 200 µA at 45 V). These differences affect power dissipation and leakage characteristics in the circuit.

Q: Are both parts available in the same packaging format?

A: Yes. Both the B245BE-13 and B250-13-F use the DO-214AA SMB surface mount package. The B250-13-F is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.

Q: What is the temperature operating range difference?

A: The B245BE-13 operates from -55°C to 150°C junction temperature, while the B250-13-F extends the low-temperature range to -65°C. Both maintain the same upper temperature limit of 150°C.

Q: Why is the B245BE-13 classified as obsolete?

A: The B245BE-13 is no longer in active production. The B250-13-F serves as the active replacement part from Diodes Incorporated, offering improved specifications and continued manufacturing support.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant. The B245BE-13 is REACH affected, while the B250-13-F is REACH unaffected. Both carry the same EAR99 ECCN classification and identical HTSUS code (8541.10.0080).
