Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF20H100CTHE3/45 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io) (per Diode): 10 A
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack configuration

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Tolerance range 770 mV to 850 mV @ 10 A
• Current - Reverse Leakage @ Vr: Range 3.5 µA to 150 µA @ 100 V
• Operating Temperature - Junction: Minimum -65°C to maximum 175°C
• Product Status: Active status preferred for ongoing availability; obsolete status indicates discontinuation
• Packaging Format: Tube or Full Pack acceptable

Substitute parts meeting these criteria maintain functional and mechanical compatibility with the original MBRF20H100CTHE3/45 design.

Engineering Selection Recommendations

Primary Substitute: MBRF20H100CT-E3/45

The MBRF20H100CT-E3/45 from Vishay General Semiconductor - Diodes Division is the direct parametric equivalent to the obsolete MBRF20H100CTHE3/45. This part maintains identical electrical specifications including 770 mV forward voltage drop at 10 A and 4.5 µA reverse leakage current at 100 V. The primary distinction is product status: MBRF20H100CT-E3/45 carries active status with 1400 units in stock, ensuring supply chain continuity. Both parts are ROHS3 compliant with MSL 1 rating and identical operating temperature range (-65°C to 175°C). The packaging differs only in format (Tube versus Full Pack), which does not affect functional compatibility.

Secondary Substitutes: STPS20H100CFP and STPS20S100CFP

The STPS20H100CFP and STPS20S100CFP from STMicroelectronics are functionally compatible alternatives. Both maintain the 100 V reverse voltage rating, 10 A current rating, and fast recovery Schottky technology. STPS20H100CFP exhibits identical 770 mV forward voltage specification, while STPS20S100CFP operates at 850 mV forward voltage. Both parts are ROHS3 compliant with MSL 1 rating. Operating temperature specification differs: both parts specify 175°C maximum junction temperature without explicit minimum rating. STPS20H100CFP offers the highest inventory availability at 105,100 units.

Tertiary Substitute: MBRF20100CTG

The MBRF20100CTG from onsemi (SWITCHMODE™ series) provides functional substitution with notable parameter variations. This part maintains 100 V reverse voltage and 10 A current ratings with identical fast recovery Schottky technology. Forward voltage specification is 850 mV at 10 A, representing a 80 mV increase from the main part. Reverse leakage current is specified at 150 µA at 100 V, significantly higher than the main part's 4.5 µA specification. Operating temperature range matches the main part (-65°C to 175°C). ROHS3 compliance is confirmed; MSL is listed as Not Applicable. This part carries active status with 34,073 units in stock.

Selection Criteria:

For applications requiring strict electrical parameter matching, MBRF20H100CT-E3/45 is the preferred selection. For applications with higher inventory requirements or extended supply chain assurance, STPS20H100CFP provides equivalent performance with superior stock availability. MBRF20100CTG is suitable for applications tolerating higher forward voltage drop and reverse leakage current specifications.

Frequently Asked Questions (FAQ)

Q: Can MBRF20H100CT-E3/45 directly replace MBRF20H100CTHE3/45 in existing designs?

A: Yes. MBRF20H100CT-E3/45 maintains identical electrical specifications (100 V reverse voltage, 10 A current rating, 770 mV forward voltage at 10 A, 4.5 µA reverse leakage) and mechanical compatibility (TO-220-3 Full Pack through-hole mounting). The only difference is packaging format (Tube versus Full Pack) and product status (Active versus Obsolete).

Q: What is the significance of the forward voltage difference between MBRF20H100CFP and MBRF20100CTG?

A: STPS20H100CFP specifies 770 mV forward voltage at 10 A, matching the original part. MBRF20100CTG specifies 850 mV at 10 A, representing an 80 mV increase. This difference affects power dissipation and thermal performance. Applications with tight thermal budgets or high-frequency switching should account for this increased voltage drop.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (MBRF20H100CT-E3/45, STPS20H100CFP, MBRF20100CTG, STPS20S100CFP) are ROHS3 compliant, meeting environmental and regulatory requirements equivalent to the original MBRF20H100CTHE3/45.

Q: What is the difference between TO-220-3 Full Pack and TO-220-3 Full Pack with Isolated Tab?

A: Both configurations use the TO-220-3 through-hole package. The isolated tab variant (MBRF20H100CTHE3/45 and MBRF20H100CT-E3/45) provides electrical isolation of the mounting tab from the diode cathode, reducing thermal coupling to ground. Standard TO-220-3 Full Pack (STPS20H100CFP, MBRF20100CTG, STPS20S100CFP) may have different tab isolation characteristics. Verify thermal and electrical isolation requirements for your specific application.

Q: Which substitute part offers the best inventory availability?

A: STPS20H100CFP from STMicroelectronics offers the highest inventory availability at 105,100 units in stock, followed by MBRF20100CTG at 34,073 units and STPS20S100CFP at 17,300 units.

Q: Can MBRF20100CTG be used in applications sensitive to reverse leakage current?

A: MBRF20100CTG specifies 150 µA reverse leakage at 100 V, compared to 4.5 µA for MBRF20H100CTHE3/45. Applications with strict leakage current requirements should use STPS20S100CFP (3.5 µA) or MBRF20H100CT-E3/45 (4.5 µA) instead.

Q: Are there differences in operating temperature range between substitute parts?

A: MBRF20H100CT-E3/45 and MBRF20100CTG specify -65°C to 175°C operating temperature range, matching the original part. STPS20H100CFP and STPS20S100CFP specify 175°C maximum without explicit minimum rating. For applications requiring full -65°C to 175°C range, use MBRF20H100CT-E3/45 or MBRF20100CTG.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life without moisture bake-out requirements. All substitute parts except MBRF20100CTG carry MSL 1 rating, providing equivalent moisture handling characteristics to the original part.
