Key Parameters

Substitute Part Grouping Explanation

Substitution of the FEPB16BTHE3_A/I is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• 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): Equal to or greater than 100 V
• Current - Average Rectified (Io) (per Diode): Equal to or greater than 8 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into three categories based on voltage rating and current capacity:

1. Direct Voltage Match (100 V): Parts maintaining the 100 V reverse voltage specification with equal or higher current ratings
2. Elevated Voltage (200 V): Parts with higher reverse voltage ratings suitable for applications requiring additional voltage margin
3. Technology Variants: Parts utilizing alternative semiconductor technologies (Schottky, Super Barrier) while maintaining electrical compatibility

Engineering Selection Recommendations

FEPB16DTHM3/I (Vishay General Semiconductor - Diodes Division)

This part is the manufacturer-recommended substitute from Vishay. It maintains identical diode configuration, package, and technology while providing doubled voltage rating (200 V) and current capacity (16 A). Both parts carry Automotive grade and AEC-Q101 qualification. This substitute is suitable for applications requiring higher voltage margin or increased current capacity within the same product family. Product status is Active, ensuring long-term availability.

SBR30A100CTB-13 (Diodes Incorporated)

This Super Barrier technology diode array maintains the 100 V voltage specification with increased current capacity (15 A). The lower forward voltage drop (850 mV @ 15 A) compared to the original part reduces power dissipation. However, reverse leakage current is higher (100 µA @ 100 V versus 10 µA @ 100 V). This substitute is suitable for applications prioritizing efficiency over leakage characteristics. Product status is Active with high inventory availability.

STPS20H100CGY-TR (STMicroelectronics)

This Schottky technology diode array maintains the 100 V voltage specification with 10 A current capacity. The significantly lower forward voltage drop (770 mV @ 10 A) and reverse leakage current (4.5 µA @ 100 V) provide superior efficiency and lower leakage performance. Operating temperature range extends to 175°C maximum. Automotive grade and AEC-Q101 qualification are provided. This substitute is suitable for applications requiring enhanced thermal performance and minimal leakage. Product status is Active.

STTH1602CG-TR (STMicroelectronics)

This standard technology diode array provides elevated voltage rating (200 V) with 10 A current capacity. Reverse recovery time is superior (26 ns versus 35 ns). Product status is Active with substantial inventory. This substitute is suitable for applications requiring higher voltage margin with improved switching characteristics.

Frequently Asked Questions (FAQ)

Q: Can FEPB16DTHM3/I be used as a direct replacement for FEPB16BTHE3_A/I?

A: Yes. FEPB16DTHM3/I is the manufacturer-recommended substitute. Both parts share identical diode configuration (1 Pair Common Cathode), package (TO-263-3, D2PAK), and mounting type (Surface Mount). FEPB16DTHM3/I provides higher voltage (200 V) and current (16 A) ratings, making it suitable for the original application with additional design margin. Both parts are Automotive grade with AEC-Q101 qualification.

Q: What is the primary difference between the Schottky substitute (STPS20H100CGY-TR) and the original part?

A: STPS20H100CGY-TR uses Schottky technology, resulting in significantly lower forward voltage drop (770 mV @ 10 A versus 950 mV @ 8 A) and lower reverse leakage current (4.5 µA @ 100 V versus 10 µA @ 100 V). These characteristics reduce power dissipation and heat generation. The voltage and configuration remain compatible at 100 V and 1 Pair Common Cathode.

Q: Are all substitute parts RoHS3 compliant?

A: FEPB16DTHM3/I, SBR30A100CTB-13, STPS20H100CGY-TR, and STTH1602CG-TR are all specified as ROHS3 Compliant. All parts maintain Moisture Sensitivity Level 1 (Unlimited).

Q: Which substitute provides the highest current capacity?

A: FEPB16DTHM3/I provides the highest current capacity at 16 A per diode, compared to 8 A for the original part. SBR30A100CTB-13 provides 15 A, while STPS20H100CGY-TR and STTH1602CG-TR provide 10 A.

Q: Can substitutes with higher voltage ratings (200 V) be used in applications designed for 100 V?

A: Yes. FEPB16DTHM3/I and STTH1602CG-TR both provide 200 V reverse voltage ratings. Higher voltage ratings are compatible with 100 V applications and provide additional design margin. No circuit modification is required.

Q: What is the difference between Super Barrier (SBR30A100CTB-13) and Schottky (STPS20H100CGY-TR) technology?

A: Both technologies provide lower forward voltage drop compared to standard rectifier diodes. SBR30A100CTB-13 achieves 850 mV @ 15 A forward voltage with higher reverse leakage (100 µA @ 100 V). STPS20H100CGY-TR achieves 770 mV @ 10 A forward voltage with lower reverse leakage (4.5 µA @ 100 V). Selection depends on application requirements for current capacity, leakage characteristics, and thermal performance.

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts use TO-263-3, D2PAK (2 Leads + Tab), TO-263AB package. Surface Mount mounting type is identical across all parts, ensuring PCB compatibility without layout modifications.

Q: Which substitute has the fastest reverse recovery time?

A: STTH1602CG-TR provides the fastest reverse recovery time at 26 ns, compared to 35 ns for the original FEPB16BTHE3_A/I. This characteristic improves switching performance in high-frequency applications.

Q: What is the product status of each substitute?

A: FEPB16DTHM3/I, SBR30A100CTB-13, STPS20H100CGY-TR, and STTH1602CG-TR are all designated as Active products, ensuring continued availability and long-term supply. The original FEPB16BTHE3_A/I is Last Time Buy, making substitution necessary for future production.
