Key Parameters

Substitute Part Grouping Explanation

Substitution of the FEPB16FTHE3_A/I is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode (electrical pinout compatibility)
• Package / Case: TO-263-3, D2PAK (mechanical and thermal compatibility)
• Voltage - DC Reverse (Vr) (Max): Minimum 300 V (electrical stress rating)
• Current - Average Rectified (Io) (per Diode): Minimum 8 A (current handling capacity)
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (switching performance)
• Mounting Type: Surface Mount (assembly process compatibility)

Acceptable Parameter Variations:

• Current - Average Rectified (Io): May exceed 8 A (higher current rating provides design margin)
• Voltage - DC Reverse (Vr): May exceed 300 V (higher voltage rating provides design margin)
• Voltage - Forward (Vf): Variations acceptable within thermal and power dissipation limits
• Reverse Recovery Time (trr): May be lower than 50 ns (improved performance)
• Operating Temperature - Junction: May exceed -55°C to 150°C range (extended operating window)

All substitute parts listed maintain identical diode configuration and package format. Current and voltage ratings meet or exceed the original specification.

Frequently Asked Questions (FAQ)

Q: Can FEPB16GTHM3/I be used as a direct replacement for FEPB16FTHE3_A/I?

A: Yes. The FEPB16GTHM3/I is the manufacturer-recommended substitute. Both parts share identical diode configuration (1 Pair Common Cathode), package format (TO-263-3 D2PAK), and automotive qualification (AEC-Q101). The FEPB16GTHM3/I provides higher voltage (400 V) and current (16 A) ratings, which are compatible with applications designed for the original 300 V / 8 A specification.

Q: What is the primary difference between Vishay and Diodes Incorporated substitutes?

A: The Vishay FEPB16GTHM3/I maintains automotive-grade qualification (AEC-Q101) identical to the original part. The Diodes Incorporated SBR40U300CTB-13 employs Super Barrier technology, offering lower forward voltage (920 mV @ 20 A) and extended temperature range (-65°C to 175°C), but automotive qualification status is not specified in the provided data.

Q: Are STMicroelectronics parts suitable for automotive applications?

A: Automotive qualification status is not specified for STTH2003CGY-TR and STTH30R03CG-TR in the provided data. If automotive-grade compliance (AEC-Q101) is a design requirement, the Vishay FEPB16GTHM3/I is the appropriate selection.

Q: What is the impact of higher current ratings in substitute parts?

A: Substitute parts with current ratings exceeding 8 A (such as 10 A, 15 A, 16 A, or 20 A) provide design margin and thermal headroom. These parts can handle the original 8 A specification with reduced junction temperature rise, improving reliability and component lifespan. No circuit modification is required.

Q: Can I use SBR40U300CTB or SBR40U300CTB-13 interchangeably?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: SBR40U300CTB is supplied in Tube format, while SBR40U300CTB-13 is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and inventory management practices.

Q: What does "1 Pair Common Cathode" configuration mean for substitution?

A: This configuration specifies the internal diode arrangement and pinout. All substitute parts listed maintain identical 1 Pair Common Cathode configuration, ensuring direct electrical compatibility without circuit redesign or PCB layout modification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (FEPB16GTHM3/I, SBR40U300CTB-13, STTH2003CGY-TR, STTH30R03CG-TR) are specified as ROHS3 Compliant, matching the original part's environmental compliance status.

Q: What is the significance of reverse recovery time (trr) differences?

A: Reverse recovery time affects switching speed and electromagnetic interference characteristics. Substitute parts with lower trr values (40 ns for STTH2003CGY-TR, 35 ns for STTH30R03CG-TR) provide faster switching performance compared to the original 50 ns specification. This improvement is compatible with the original design and may reduce switching losses.
