Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the STD5100C are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Substitute may have higher forward voltage within acceptable design margins
• Current - Reverse Leakage @ Vr: Substitute may have lower reverse leakage (improved performance)
• Operating Temperature - Junction (Max): Substitute may have higher maximum junction temperature (extended thermal capability)
• Current - Average Rectified (Io) (per Diode): Substitute may have specified current rating where main part does not

The STPS15H100CB meets all critical matching parameters and qualifies as a direct substitute for the STD5100C.

Engineering Selection Recommendations

STD5100C (Primary Selection)

The STD5100C remains the primary component choice when available. This part is Active in product status, ROHS3 Compliant, and REACH Affected. It is currently in stock with 824 pieces available in Tape & Reel packaging.

STPS15H100CB (Substitute Selection)

The STPS15H100CB qualifies as a direct substitute when STD5100C availability is constrained. This part is manufactured by STMicroelectronics and is Active in product status with ROHS3 Compliance. The STPS15H100CB is REACH Unaffected and currently in stock with 6080 pieces available in Tube packaging.

Substitution Basis:

Both parts share identical electrical ratings for voltage (100 V DC reverse), diode configuration (1 Pair Common Cathode), technology (Schottky), and package type (TO-252-3 DPAK SC-63). Both parts meet the same RoHS and MSL requirements.

The STPS15H100CB demonstrates improved performance characteristics: lower reverse leakage current (3 µA versus 180 µA at 100 V) and higher maximum junction temperature (175°C versus 150°C). Forward voltage is slightly higher (800 mV versus 750 mV at 7.5 A), which is within acceptable design tolerance for Schottky diode applications.

Both parts are Active products with unlimited moisture sensitivity levels and are suitable for Surface Mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can STPS15H100CB be used as a direct replacement for STD5100C in existing designs?

A: Yes. Both parts share identical voltage ratings (100 V), diode configuration (1 Pair Common Cathode), Schottky technology, and TO-252-3 DPAK package. Electrical and mechanical compatibility is confirmed across all critical parameters.

Q: What are the differences between STD5100C and STPS15H100CB?

A: The primary differences are: (1) Reverse leakage current is lower in STPS15H100CB (3 µA versus 180 µA at 100 V), indicating improved performance; (2) Maximum junction temperature is higher in STPS15H100CB (175°C versus 150°C); (3) Forward voltage is slightly higher in STPS15H100CB (800 mV versus 750 mV at 7.5 A); (4) Manufacturers differ (SMC Diode Solutions versus STMicroelectronics); (5) Packaging differs (Tape & Reel versus Tube).

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 Compliant and have MSL rating of 1 (Unlimited). The STD5100C is REACH Affected, while the STPS15H100CB is REACH Unaffected. Both parts carry EAR99 ECCN classification and share the same HTSUS code (8541.10.0080).

Q: Does the higher forward voltage of STPS15H100CB affect circuit performance?

A: The forward voltage difference is 50 mV (800 mV versus 750 mV at 7.5 A). This difference is within typical design tolerance for Schottky diode rectifier applications and does not prevent substitution. Circuit designers should verify this parameter against specific application requirements.

Q: What is the significance of the lower reverse leakage current in STPS15H100CB?

A: Lower reverse leakage current (3 µA versus 180 µA at 100 V) indicates improved diode quality and reduced power dissipation in reverse bias conditions. This represents enhanced performance and is not a limitation for substitution.

Q: Can these parts be used interchangeably in high-temperature applications?

A: The STPS15H100CB supports higher maximum junction temperature (175°C versus 150°C). For applications operating near or above 150°C, the STPS15H100CB provides extended thermal capability. For applications below 150°C, both parts are suitable.

Q: Are there packaging considerations for substitution?

A: The STD5100C is supplied in Tape & Reel packaging, while STPS15H100CB is supplied in Tube packaging. Both use identical TO-252-3 DPAK SC-63 surface mount packages. Packaging format affects handling and assembly processes but does not affect electrical or mechanical compatibility.
