Key Parameters

Substitute Part Grouping Explanation

Substitution of the SBLB1640CTHE3_A/I is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Diode configuration (1 Pair Common Cathode)
• Technology (Schottky)
• Maximum DC reverse voltage (40 V)
• Average rectified current per diode (8 A)
• Forward voltage drop (550 mV @ 8 A)
• Reverse leakage current (500 µA @ 40 V)
• Recovery speed (Fast Recovery ≤ 500 ns, > 200 mA)

Mechanical & Environmental Parameters:

• Package type (TO-263-3, D2PAK, TO-263AB)
• Surface Mount mounting type
• Operating temperature range (-40°C ~ 125°C)
• Automotive grade qualification
• AEC-Q101 certification

Compliance Parameters:

• ROHS3 compliance
• MSL rating (1 - Unlimited)

Substitute parts must match all electrical specifications, package configuration, and automotive qualification requirements. Packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

SBLB1640CTHE3_A/I (Main Part - Active Status)

The SBLB1640CTHE3_A/I is the primary selection for new designs and ongoing production. This part maintains Active product status with continuous manufacturing support from Vishay. Current inventory of 775 units supports immediate procurement requirements. The part carries full AEC-Q101 automotive qualification and ROHS3 compliance, meeting all regulatory and quality standards for automotive and industrial applications.

SBLB1640CTHE3_B/I (Substitute - Last Time Buy Status)

The SBLB1640CTHE3_B/I is electrically and mechanically identical to the main part and is available in Tape & Reel packaging format. This part is designated Last Time Buy, indicating limited future availability. Current inventory of 1824 units in Tape & Reel format provides supply for high-volume production runs. Selection of this substitute is appropriate for applications requiring reel packaging or where existing procurement agreements specify this format. After Last Time Buy completion, this part number will no longer be available from the manufacturer.

Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, automotive qualification, and compliance certifications. Selection between these parts is determined by packaging format requirements and supply chain planning considerations.

Frequently Asked Questions (FAQ)

Q: Are the SBLB1640CTHE3_A/I and SBLB1640CTHE3_B/I electrically identical?

A: Yes. Both parts are Schottky diode arrays with identical electrical specifications: 40 V maximum reverse voltage, 8 A average rectified current per diode, 550 mV forward voltage drop at 8 A, and 500 µA reverse leakage current at 40 V. Both operate across the same temperature range (-40°C to 125°C) and meet AEC-Q101 automotive qualification requirements.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The SBLB1640CTHE3_A/I is supplied in bulk packaging, while the SBLB1640CTHE3_B/I is supplied in Tape & Reel (TR) format. The SBLB1640CTHE3_B/I is designated Last Time Buy, indicating limited future availability.

Q: Can I use SBLB1640CTHE3_B/I as a direct replacement for SBLB1640CTHE3_A/I in production?

A: Yes, for applications where Tape & Reel packaging is compatible with your assembly process. Both parts are mechanically and electrically equivalent. Verify that your pick-and-place equipment and tape specifications support the reel format.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the SBLB1640CTHE3_A/I and SBLB1640CTHE3_B/I carry Automotive grade designation and AEC-Q101 qualification, meeting automotive industry reliability and quality standards.

Q: What does Last Time Buy status mean for the SBLB1640CTHE3_B/I?

A: Last Time Buy indicates that Vishay will discontinue manufacturing this part number after current inventory is depleted. No new production runs are planned. Existing inventory of 1824 units represents the final available supply. For long-term production requirements, transition to the Active part number SBLB1640CTHE3_A/I.

Q: Do these parts require different handling or storage procedures?

A: Both parts share identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard ESD precautions apply to both parts.

Q: Can I mix SBLB1640CTHE3_A/I and SBLB1640CTHE3_B/I in the same production batch?

A: Yes. Both parts are electrically and mechanically equivalent and carry identical certifications. Mixing is acceptable from a technical standpoint. Verify that your quality and traceability procedures accommodate multiple part numbers in a single production lot.
