Key Parameters

Substitute Part Grouping Explanation

Substitution of the FESB16GTHE3_A/I is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 16 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 16 A
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 400 V
• Capacitance @ Vr, F: 175 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• Qualification: AEC-Q101
• Technology: Standard

Substitute parts identified below meet all electrical, mechanical, and compliance requirements and are therefore functionally interchangeable with the FESB16GTHE3_A/I in circuit applications.

Engineering Selection Recommendations

FESB16GTHM3/I is the manufacturer-recommended substitute for the FESB16GTHE3_A/I. This part carries Active product status, ensuring ongoing availability and long-term supply chain support. The FESB16GTHM3/I maintains full electrical and mechanical equivalence with the original part and retains AEC-Q101 automotive qualification. Selection of this part is appropriate for new designs and production continuity where the original part is no longer available.

FESB16GT-E3/81 is a parametric equivalent substitute that matches all electrical and mechanical specifications of the FESB16GTHE3_A/I. This part is supplied in Tape & Reel packaging and currently maintains higher inventory availability (3028 pcs) compared to the main part. However, this part carries Last Time Buy status, indicating future discontinuation. The FESB16GT-E3/81 is suitable for immediate component sourcing but should not be selected for long-term production planning without confirmation of extended availability.

Both substitute parts are manufactured by Vishay General Semiconductor - Diodes Division and are direct functional replacements requiring no circuit modifications or design changes.

Frequently Asked Questions (FAQ)

Q: Can FESB16GTHM3/I be used as a direct replacement for FESB16GTHE3_A/I?

A: Yes. The FESB16GTHM3/I is electrically and mechanically identical to the FESB16GTHE3_A/I across all specified parameters. Both parts feature 400 V reverse voltage rating, 16 A average rectified current, 1.3 V forward voltage drop, 50 ns reverse recovery time, and identical TO-263AB packaging. No circuit modifications are required.

Q: What is the difference between FESB16GTHE3_A/I and FESB16GT-E3/81?

A: Both parts are parametrically equivalent with identical electrical ratings and mechanical packaging. The primary differences are product status (FESB16GTHE3_A/I is Last Time Buy; FESB16GT-E3/81 is also Last Time Buy) and packaging format (FESB16GTHE3_A/I is supplied in Tape & Reel; FESB16GT-E3/81 is also supplied in Tape & Reel). Both are suitable for direct substitution.

Q: Are these parts suitable for automotive applications?

A: The FESB16GTHE3_A/I and FESB16GTHM3/I are both qualified to AEC-Q101 automotive standards and carry automotive grade designation. The FESB16GT-E3/81 meets all electrical and mechanical requirements but does not specify AEC-Q101 qualification in the provided data. For automotive applications requiring AEC-Q101 certification, FESB16GTHM3/I is the recommended selection.

Q: What is the significance of Last Time Buy status?

A: Last Time Buy status indicates that the manufacturer has announced discontinuation of the part. FESB16GTHE3_A/I and FESB16GT-E3/81 both carry this status. FESB16GTHM3/I carries Active status, indicating ongoing production and availability. For new designs and long-term production requirements, FESB16GTHM3/I is the appropriate selection.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All three parts use identical TO-263AB (D2PAK) packaging with the same pinout and mechanical footprint. No PCB layout modifications are required for substitution.

Q: What are the key electrical parameters that determine substitutability?

A: The critical parameters are: 400 V DC reverse voltage rating, 16 A average rectified current, 1.3 V maximum forward voltage at 16 A, 50 ns reverse recovery time, 10 µA reverse leakage current at 400 V, and 175 pF capacitance at 4 V and 1 MHz. All substitute parts match these specifications exactly.
