Substitute Part Grouping Explanation

Substitution of the MBR20100PT is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

Diode Configuration: 1 Pair Common Cathode
Technology: Schottky
Voltage - DC Reverse (Vr) (Max): 100 V
Mounting Type: Through Hole
Package / Case: TO-247-3

Secondary Compatibility Criteria:

Current - Average Rectified (Io) (per Diode): 20 A or greater
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Operating Temperature Range: Must encompass or exceed -55°C to 150°C
RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories:

Parametric Equivalent: MBR20100PTHC0G matches all primary and secondary criteria with identical electrical specifications and adds automotive-grade qualification (AEC-Q101).

Direct Manufacturer Equivalent: MBR20100WT is a variant from an alternative manufacturer (SMC Diode Solutions) with identical base product number and configuration, though with different forward voltage and leakage characteristics.

Similar Substitutes: STPS40H100CW, STPS61H100CW, STPS30H100CW, and VS-30CPQ100-N3 maintain primary equivalence criteria but vary in current ratings and electrical performance characteristics. These parts are suitable for applications where the specified current rating of 20 A is not exceeded and where forward voltage and leakage variations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can MBR20100PTHC0G be used as a direct replacement for MBR20100PT?

A: Yes. MBR20100PTHC0G is a parametric equivalent with identical electrical specifications, same diode configuration, same voltage and current ratings, and same package type. The part is currently in active production status.

Q: What is the primary difference between MBR20100PT and MBR20100WT?

A: Both parts share the same base product number and configuration. MBR20100WT is manufactured by SMC Diode Solutions instead of Taiwan Semiconductor Corporation. Forward voltage is lower (850 mV @ 10 A vs. 950 mV @ 20 A), and reverse leakage is higher (1 mA @ 100 V vs. 100 µA @ 100 V). MBR20100WT has affected REACH status.

Q: Why do the STMicroelectronics parts (STPS series) have different current ratings?

A: The STPS series represents different product lines within STMicroelectronics' Schottky diode portfolio. STPS30H100CW is rated for 15 A, STPS40H100CW for 20 A, and STPS61H100CW for 30 A. All maintain the same 100 V reverse voltage and TO-247-3 package, but with different current handling capabilities and forward voltage characteristics.

Q: Can STPS30H100CW be used in place of MBR20100PT?

A: STPS30H100CW can be used only if the application's maximum current requirement does not exceed 15 A. The part is rated for 15 A average rectified current, which is lower than the MBR20100PT's 20 A rating. All other electrical and mechanical parameters are compatible.

Q: What are the advantages of STPS40H100CW over MBR20100PT?

A: STPS40H100CW offers lower forward voltage (730 mV @ 20 A vs. 950 mV @ 20 A), lower reverse leakage (10 µA @ 100 V vs. 100 µA @ 100 V), and higher maximum operating temperature (175°C vs. 150°C). These characteristics result in reduced power dissipation and improved thermal performance.

Q: Is VS-30CPQ100-N3 suitable for all applications using MBR20100PT?

A: VS-30CPQ100-N3 is suitable for applications where the current requirement does not exceed 30 A and where higher forward voltage (1.05 V @ 30 A) and significantly higher reverse leakage (550 µA @ 100 V) are acceptable. The part maintains the same 100 V reverse voltage and TO-247-3 package configuration.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. MBR20100WT has affected REACH status, which may require additional compliance verification for certain supply chain applications.

Q: What is the significance of AEC-Q101 qualification on MBR20100PTHC0G?

A: AEC-Q101 is an automotive-grade qualification standard. MBR20100PTHC0G carries this qualification, indicating enhanced reliability testing and documentation suitable for automotive applications. The original MBR20100PT does not specify this qualification.

Q: Can these parts be used interchangeably in the same PCB layout?

A: Yes. All substitute parts use the TO-247-3 through-hole package with identical pin configuration and mechanical dimensions. PCB layout and thermal management considerations remain the same across all listed parts.

Q: What is the inventory status of substitute parts?

A: MBR20100PTHC0G has 643 units in stock, MBR20100WT has 1143 units, STPS40H100CW has 2921 units, STPS30H100CW has 22238 units, STPS61H100CW has 9230 units, and VS-30CPQ100-N3 has 9800 units in stock.
