Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBR30100PT is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Mounting Type: Through Hole
• Package / Case: TO-247-3
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Current Rating Consideration: The MBR30100PT specifies 30 A average rectified current per diode. Substitute parts are classified into two categories:

1. Direct Equivalents: Parts with matching 30 A current rating (MBR30100WT, STPS61H100CW)
2. Similar Substitutes: Parts with lower current ratings (15 A or 20 A) that maintain all other electrical and mechanical parameters but operate within reduced current specifications (STPS30H100CW, STPS40H100CW)

The 30CPQ100 is classified as a direct equivalent despite undeclared current rating specifications, as it matches all declared electrical parameters and package configuration.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended for 1:1 Replacement):

The 30CPQ100 (SMC Diode Solutions) and MBR30100WT (SMC Diode Solutions) are classified as direct equivalents to the MBR30100PT. Both parts maintain identical electrical specifications for reverse voltage, diode configuration, technology, package type, and fast recovery speed characteristics. Both are ROHS3 compliant with MSL 1 rating. The 30CPQ100 offers extended operating temperature range to 175°C compared to the MBR30100PT specification of 150°C maximum junction temperature. The MBR30100WT maintains the identical -55 to 150°C operating range as the original part. Selection between these direct equivalents is based on inventory availability and application temperature requirements.

Current-Rated Alternatives (Application-Dependent Selection):

The STPS61H100CW (STMicroelectronics) is a full electrical and thermal equivalent to the MBR30100PT, matching the 30 A current rating specification while providing superior reverse leakage characteristics (16 µA versus 500 µA at 100 V). This part is suitable for direct substitution in applications requiring the full 30 A current capacity.

The STPS40H100CW (STMicroelectronics) and STPS30H100CW (STMicroelectronics) are current-limited alternatives rated at 20 A and 15 A respectively. These parts are suitable only for applications where the circuit design operates below their respective current ratings. Both STMicroelectronics parts offer extended maximum junction temperature to 175°C and superior reverse leakage performance compared to the original MBR30100PT specification.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and through-hole TO-247-3 packaging. Product status for all listed parts is Active.

Frequently Asked Questions (FAQ)

Q: Can the 30CPQ100 be used as a direct replacement for the MBR30100PT?

A: Yes. The 30CPQ100 matches all critical electrical parameters including 100 V reverse voltage rating, 1 Pair Common Cathode configuration, Schottky technology, fast recovery speed, and TO-247-3 through-hole packaging. Both parts are ROHS3 compliant with MSL 1 rating. The 30CPQ100 provides extended operating temperature range to 175°C.

Q: What is the difference between direct equivalents and similar substitutes?

A: Direct equivalents (30CPQ100, MBR30100WT, STPS61H100CW) maintain the 30 A average rectified current specification of the MBR30100PT. Similar substitutes (STPS30H100CW at 15 A, STPS40H100CW at 20 A) operate at reduced current ratings and are suitable only for applications where circuit current requirements do not exceed their respective ratings.

Q: Are all substitute parts compatible with the TO-247-3 footprint?

A: Yes. All listed substitute parts use the TO-247-3 through-hole package configuration, ensuring mechanical and thermal compatibility with the original MBR30100PT footprint.

Q: What are the reverse leakage differences between substitute parts?

A: The MBR30100PT specifies 500 µA reverse leakage at 100 V. The 30CPQ100 specifies 550 µA, MBR30100WT specifies 1 mA, STPS30H100CW specifies 5 µA, STPS40H100CW specifies 10 µA, and STPS61H100CW specifies 16 µA at 100 V. Lower reverse leakage values indicate superior performance characteristics.

Q: Can STPS30H100CW or STPS40H100CW be used in applications designed for 30 A operation?

A: No. The STPS30H100CW is rated for 15 A maximum average rectified current and STPS40H100CW is rated for 20 A maximum. These parts are suitable only for applications where the actual circuit current does not exceed their respective ratings. For full 30 A operation, use STPS61H100CW, 30CPQ100, or MBR30100WT.

Q: What is the operating temperature range difference between the MBR30100PT and substitute parts?

A: The MBR30100PT operates from -55°C to 150°C junction temperature. The 30CPQ100 and STMicroelectronics parts (STPS30H100CW, STPS40H100CW, STPS61H100CW) extend the maximum junction temperature to 175°C. The MBR30100WT maintains the -55°C to 150°C range identical to the original part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the environmental compliance profile of the MBR30100PT.

Q: What forward voltage differences exist between substitute parts?

A: Forward voltage specifications vary by manufacturer and current rating. The 30CPQ100 specifies 860 mV at 15 A, MBR30100WT specifies 850 mV at 15 A, STPS30H100CW specifies 800 mV at 15 A, STPS40H100CW specifies 730 mV at 20 A, and STPS61H100CW specifies 790 mV at 30 A. Lower forward voltage values indicate reduced power dissipation at equivalent current levels.
