Mandatory Compatibility Parameters:

Diode Configuration: 1 Pair Common Cathode
Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
Mounting Type: Surface Mount
Voltage - DC Reverse (Vr) (Max): 200 V minimum

Performance Parameters (Equal or Superior):

Current - Average Rectified (Io) (per Diode): 8 A minimum
Voltage - Forward (Vf) (Max): Equal or lower forward voltage drop
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Engineering Selection Recommendations

Primary Recommendation - FEPB16DTHM3/I (Vishay): This part is the manufacturer-recommended direct replacement from Vishay. It maintains identical voltage and package specifications while providing doubled current capacity (16 A vs. 8 A). The part is in Active product status with full AEC-Q101 automotive qualification. Forward voltage characteristics remain identical at 950 mV @ 8 A, ensuring circuit compatibility. This selection eliminates design re-qualification requirements.

Secondary Recommendations - 10 A Rated Parts: The following parts provide equivalent functionality with 10 A current ratings and maintain 200 V reverse voltage specifications:

DURB2020CT (Littelfuse): Active status with high inventory availability (24,654 pcs). Standard technology with 35 ns recovery time. Forward voltage is 1.15 V @ 10 A, representing a 200 mV increase from the original specification.
FFB20UP20DN-F085 (onsemi): Active status with AEC-Q101 automotive qualification. Extended operating temperature range to 175°C. Forward voltage is 1.15 V @ 10 A with improved recovery time of 40 ns.
SBR20A200CTB / SBR20A200CTB-13 (Diodes Incorporated): Active status with Super Barrier technology. Both variants provide 10 A current rating with 30 ns recovery time. Forward voltage is 960 mV @ 20 A. Extended operating temperature to 175°C. Available in both Tube and Tape & Reel packaging.
STTH1602CG-TR (STMicroelectronics): Active status with 10 A current rating and 200 V reverse voltage. Forward voltage is 1.1 V @ 8 A with superior 26 ns recovery time. Extended operating temperature to 175°C.

Alternative for Lower Current Applications - SBR10200CTB-13-G (Diodes Incorporated): This part is suitable only for applications where 5 A current per diode is acceptable. It features Super Barrier technology with the lowest forward voltage (920 mV @ 5 A) and fastest recovery time (20 ns). Extended operating temperature to 175°C.

Frequently Asked Questions (FAQ)

Q: Can FEPB16DTHM3/I be used as a direct replacement for FEPB16DTHE3_A/P?

A: Yes. FEPB16DTHM3/I is the manufacturer-recommended replacement from Vishay. Both parts share identical voltage (200 V), package (TO-263-3 D2PAK), and forward voltage characteristics (950 mV @ 8 A). The primary difference is increased current capacity (16 A vs. 8 A), which provides design margin without requiring circuit modifications.

Q: What is the impact of using a 10 A rated part instead of the original 8 A part?

A: A 10 A rated part provides increased current capacity, which is beneficial for design margin and thermal performance. The part will operate within its specifications at the original 8 A design current. Forward voltage characteristics may differ slightly depending on the substitute selected, which should be verified against circuit requirements.

Q: Are all substitute parts automotive qualified?

A: Not all substitutes carry automotive qualification. FEPB16DTHM3/I, FFB20UP20DN-F085, and STPS40170CGY-TR are AEC-Q101 qualified. DURB2020CT, SBR10200CTB-13-G, SBR20A200CTB, SBR20A200CTB-13, and STTH1602CG-TR do not list AEC-Q101 qualification in the provided specifications. Automotive applications should prioritize AEC-Q101 qualified parts.

Q: What is the difference between Standard and Super Barrier technology?

A: Super Barrier technology (used in SBR series parts) typically offers lower forward voltage drop and faster recovery times compared to Standard technology. The SBR10200CTB-13-G and SBR20A200CTB series demonstrate these characteristics with forward voltages of 920-960 mV and recovery times of 20-30 ns.

Q: Can STPS40170CGY-TR be used as a substitute?

A: STPS40170CGY-TR is not recommended as a direct substitute. While it maintains the TO-263-3 D2PAK package and provides higher current capacity (20 A), the reverse voltage rating is reduced to 170 V, which is below the 200 V specification of the original part. This part is suitable only for applications with lower voltage requirements.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tube, Tape & Reel (TR), and Cut Tape (CT) & Digi-Reel®. The original FEPB16DTHE3_A/P is supplied in Tube packaging. Tape & Reel packaging is standard for high-volume production. Packaging selection should align with assembly process requirements.

Q: How do forward voltage differences affect circuit performance?

A: Forward voltage differences directly impact voltage drop across the diode and power dissipation. The original part specifies 950 mV @ 8 A. Substitutes range from 920 mV to 1.15 V depending on technology and current rating. Higher forward voltages result in increased power loss and heat generation. Circuit designs with tight voltage budgets should account for these differences.

Q: Is moisture sensitivity a concern for these parts?

A: All listed parts have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity. These parts do not require special moisture control during storage or handling.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, matching the environmental compliance status of the original FEPB16DTHE3_A/P.
