Engineering Selection Recommendations

The APD240VGTR-G1 is classified as obsolete. Both substitute parts—SB240-E3/54 and SB240-E3/73 from Vishay General Semiconductor - Diodes Division—are active products with identical electrical and mechanical specifications.

Selection Basis:

Both SB240-E3/54 and SB240-E3/73 are direct parametric equivalents to the APD240VGTR-G1. The selection between these two Vishay alternatives is determined by packaging and inventory availability:

SB240-E3/54: Supplied in Cut Tape (CT) packaging with 1600 pieces in stock
SB240-E3/73: Supplied in Cut Tape (CT) packaging with 5300 pieces in stock

Both parts maintain ROHS3 compliance and are suitable for direct substitution in applications requiring 40 V, 2 A Schottky rectifier diodes in DO-15 through-hole configuration. The active product status of both alternatives ensures long-term component availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can SB240-E3/54 or SB240-E3/73 be used as direct replacements for APD240VGTR-G1?

A: Yes. Both Vishay parts are direct parametric equivalents. All electrical ratings (40 V reverse voltage, 2 A average rectified current, 500 mV forward voltage at 2 A, fast recovery speed, and reverse leakage current) are identical. Both use the same DO-15 through-hole package configuration.

Q: What is the difference between SB240-E3/54 and SB240-E3/73?

A: Both parts are electrically and mechanically identical. The difference is in the packaging format (both are Cut Tape) and inventory availability. SB240-E3/73 has higher stock levels (5300 pieces versus 1600 pieces).

Q: Are there any compliance differences between the main part and substitutes?

A: All three parts are ROHS3 compliant. Both substitute parts are REACH Unaffected, while the original APD240VGTR-G1 is REACH Affected. Both alternatives carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Can these diodes be used in the same PCB layout without modification?

A: Yes. All three parts use identical through-hole axial package geometry (DO-204AC / DO-15). No PCB layout changes are required for substitution.

Q: Why is the APD240VGTR-G1 listed as obsolete?

A: The APD240VGTR-G1 is classified as obsolete by the manufacturer. Active equivalent alternatives are available from Vishay with identical specifications, ensuring continued design support and component availability.

Q: What is the operating temperature range for these diodes?

A: The junction operating temperature range is -65°C to 125°C for all three parts, providing identical thermal performance specifications.
