STPS5H100B Equivalent & Substitute Parts

Part Overview

The STPS5H100B is a Schottky rectifier diode rated for 100 V DC reverse voltage and 5 A average rectified current in a surface mount DPAK package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1) and is suitable for fast recovery applications requiring switching speeds of 500 ns or less at currents exceeding 200 mA.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS5H100B is determined by strict equivalence in the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 5 A
• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• RoHS Status: ROHS3 Compliant

Direct Equivalents maintain identical electrical ratings and package specifications. These parts are interchangeable without circuit modification.

Similar Substitutes meet the core voltage, current, and technology requirements but may differ in secondary parameters such as forward voltage, reverse leakage current, or package variant. These parts require verification of application-specific performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

STPS5H100BY-TR (STMicroelectronics)

This part is a direct equivalent to the STPS5H100B with identical electrical specifications and DPAK packaging. The STPS5H100BY-TR is in active production status with automotive-grade qualification (AEC-Q101) and extended operating temperature range (-40°C to 175°C). This part is recommended as the primary replacement for obsolete STPS5H100B applications. ROHS3 compliance and REACH unaffected status are maintained.

MBRD5H100T4G (onsemi)

This part meets all core electrical and mechanical requirements with identical voltage, current, and package specifications. The MBRD5H100T4G is part of the SWITCHMODE™ series and offers the lowest forward voltage (710 mV @ 5 A) among available substitutes. Operating temperature range extends to -65°C, providing enhanced low-temperature performance. ROHS3 compliance and REACH unaffected status are maintained. This part is suitable for applications requiring optimized thermal performance.

MBRD5100 (SMC Diode Solutions)

This part maintains voltage, current, and package equivalence but exhibits higher forward voltage (850 mV @ 5 A) and reverse leakage current (1 mA @ 100 V) compared to the main part. Operating temperature maximum is limited to 150°C. REACH status is affected. This part is suitable only where forward voltage and leakage characteristics are not critical design constraints.

DST5100S (Littelfuse Inc.)

This part differs in package configuration, using TO-277B (3-PowerDFN) instead of DPAK. While electrical specifications are equivalent, the package change requires PCB layout modification. Automotive-grade qualification (AEC-Q101) is provided. This part is suitable only where package footprint change is acceptable and thermal management via the PowerDFN package is beneficial.

Frequently Asked Questions (FAQ)

Q: Can STPS5H100BY-TR be used as a direct replacement for STPS5H100B?

A: Yes. STPS5H100BY-TR is a direct equivalent with identical voltage (100 V), current (5 A), forward voltage (730 mV @ 5 A), and DPAK package specifications. No circuit modification is required. The part is in active production with automotive qualification.

Q: What is the difference between MBRD5H100T4G and STPS5H100BY-TR?

A: Both parts meet core electrical and package requirements. MBRD5H100T4G offers lower forward voltage (710 mV vs. 730 mV @ 5 A) and extended low-temperature operation (-65°C vs. -40°C minimum). STPS5H100BY-TR is STMicroelectronics manufacture with automotive qualification. Selection depends on thermal performance and temperature range requirements.

Q: Why is DST5100S listed as a similar substitute rather than a direct equivalent?

A: DST5100S uses a TO-277B package instead of DPAK. Although electrical specifications are equivalent, the different package footprint requires PCB layout redesign. The part is suitable only where package change is acceptable.

Q: Is MBRD5100 suitable for all applications?

A: MBRD5100 meets voltage and current requirements but exhibits higher forward voltage (850 mV vs. 730 mV @ 5 A) and significantly higher reverse leakage (1 mA vs. 3.5 µA @ 100 V). Operating temperature is limited to 150°C maximum. This part is suitable only where these parameter variations do not impact circuit performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. MBRD5100 has affected REACH status; all other parts have unaffected REACH status.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the main part and all substitutes, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used in automotive applications?

A: STPS5H100BY-TR, DST5100S, and MBRD5H100T4G carry automotive-grade qualification (AEC-Q101). MBRD5100 does not specify automotive qualification. Automotive application requirements should be verified against specific qualification documentation.
