Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the STPS30M100SFP are qualified based on the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io): 30 A minimum per diode element
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack or equivalent isolated tab variants (ITO-220AB)
• Supplier Device Package: TO-220FPAB, ITO-220AB

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Product Status: Active

Substitute parts may include diode arrays with 1 Pair Common Cathode configuration, provided the per-diode current rating meets or exceeds 30 A and all electrical parameters remain within specified tolerances. Forward voltage (Vf) variations are acceptable within the range of 800 mV to 940 mV at rated current, as these reflect normal manufacturing variations across different semiconductor manufacturers.

Parameter Comparison

Engineering Selection Recommendations

DSTF30100S (Littelfuse Inc.) is a direct functional equivalent meeting all electrical and mechanical requirements. This part maintains 100 V reverse voltage and 30 A current ratings with fast recovery characteristics. The isolated tab TO-220-3 package provides enhanced thermal management compared to standard TO-220FPAB. RoHS3 compliance and REACH unaffected status confirm regulatory alignment. Operating temperature range extends to -55°C, providing broader thermal operating envelope.

MBRF30100CT (Taiwan Semiconductor Corporation) is a 1 Pair Common Cathode diode array configuration with per-diode ratings of 100 V and 30 A. This part meets all electrical specifications with fast recovery performance. The isolated tab package and extended operating temperature range (-55°C to 150°C) support diverse application requirements. RoHS3 compliance and REACH unaffected status confirm regulatory qualification.

MBRF30100CTP (SMC Diode Solutions) is a 1 Pair Common Cathode diode array with 100 V reverse voltage rating. Forward voltage specification at 15 A (850 mV) indicates lower conduction losses at reduced current levels. Fast recovery characteristics and isolated tab packaging are maintained. RoHS3 compliance is confirmed; however, REACH status is listed as affected, requiring verification for applications subject to REACH regulations.

All substitute parts are active products with current manufacturing status and established supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can MBRF30100CT and MBRF30100CTP be used as direct replacements for STPS30M100SFP?

A: MBRF30100CT and MBRF30100CTP are diode arrays with 1 Pair Common Cathode configuration, whereas STPS30M100SFP is a single diode. These parts are functionally equivalent when the circuit topology accommodates the common cathode configuration. Per-diode electrical ratings (100 V, 30 A) match the main part specifications. Circuit design review is required to confirm compatibility with the array configuration.

Q: What is the difference between TO-220FPAB and ITO-220AB packages?

A: Both are TO-220-3 Full Pack configurations with isolated tabs. TO-220FPAB is the STMicroelectronics supplier designation, while ITO-220AB is the industry standard designation used by Littelfuse and other manufacturers. The isolated tab feature in both variants provides electrical isolation between the tab and the semiconductor junction, enabling independent thermal management of multiple devices on a common heatsink.

Q: Are there differences in forward voltage drop between substitute parts?

A: Forward voltage specifications vary across manufacturers: STPS30M100SFP (800 mV @ 30 A), DSTF30100S (900 mV @ 30 A), MBRF30100CT (940 mV @ 30 A), and MBRF30100CTP (850 mV @ 15 A). These variations reflect different semiconductor process technologies and junction designs. Selection should account for power dissipation requirements and thermal management capacity in the target application.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current values range from 1 µA to 1 mA across substitute parts. Lower leakage current (DSTF30100S at 1 µA) indicates superior reverse blocking characteristics and reduced standby power consumption. Higher leakage (MBRF30100CTP at 1 mA) may impact applications with stringent standby power requirements. Selection depends on application-specific leakage current tolerance.

Q: Does REACH affected status for MBRF30100CTP restrict its use?

A: REACH affected status indicates the part contains substances of concern requiring compliance documentation. This does not prohibit use but requires verification against specific application regulatory requirements. Applications subject to REACH regulations should confirm compliance with supply chain documentation. DSTF30100S and MBRF30100CT maintain REACH unaffected status for unrestricted use.

Q: Can substitute parts operate at the full -55°C to 150°C temperature range?

A: DSTF30100S, MBRF30100CT, and MBRF30100CTP specify operating temperature range of -55°C to 150°C. STPS30M100SFP specifies maximum junction temperature of 150°C without explicit minimum temperature rating. Substitute parts with extended temperature range provide design margin for applications requiring operation below 0°C.
