The substitute parts STPS30150CFP (STMicroelectronics) and VF30150C-E3/4W (Vishay General Semiconductor - Diodes Division) satisfy all critical electrical and mechanical requirements. Both devices maintain the same diode configuration, reverse voltage rating, current rating, and fast recovery speed characteristics. Both are packaged in TO-220-3 Full Pack through-hole configurations and comply with RoHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

STPS30150CFP (STMicroelectronics) is the primary substitute for the MBRF30H150CTH. This device maintains full electrical and mechanical compatibility with identical reverse voltage, current rating, and fast recovery speed specifications. The STPS30150CFP exhibits superior forward voltage characteristics (920 mV versus 1.11 V at 15 A) and significantly lower reverse leakage current (6.5 µA versus 60 µA at 150 V). The device carries active product status with ROHS3 compliance and REACH unaffected designation. Packaging is standard TO-220-3 Full Pack in tube format.

VF30150C-E3/4W (Vishay General Semiconductor - Diodes Division) is an alternative substitute that maintains full electrical and mechanical compatibility. This device is part of the TMBS® series and features an isolated tab variant of the TO-220-3 Full Pack package (ITO-220AB). The VF30150C-E3/4W carries active product status with ROHS3 compliance and REACH unaffected designation. Forward voltage is 1.36 V at 15 A, and reverse leakage current is 200 µA at 150 V. The extended operating temperature range (-55 to 150°C) provides additional thermal margin compared to the original part.

Both substitute parts satisfy all mandatory electrical and mechanical requirements for direct replacement of the obsolete MBRF30H150CTH. Selection between the two substitutes depends on specific application requirements regarding forward voltage losses, reverse leakage characteristics, and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can STPS30150CFP and VF30150C-E3/4W be used interchangeably with MBRF30H150CTH?

A: Both substitute parts maintain identical diode configuration (1 pair common cathode), reverse voltage rating (150 V), current rating (15 A per diode), and fast recovery speed characteristics. Both are packaged in TO-220-3 Full Pack through-hole configurations. Electrical and mechanical compatibility is confirmed. Selection between substitutes depends on application-specific requirements for forward voltage, reverse leakage, and operating temperature range.

Q: What are the differences in forward voltage between the three parts?

A: The MBRF30H150CTH specifies 1.11 V forward voltage at 15 A. The STPS30150CFP operates at 920 mV at 15 A, representing lower forward voltage loss. The VF30150C-E3/4W operates at 1.36 V at 15 A, representing higher forward voltage. Forward voltage differences affect power dissipation in the application circuit.

Q: Are there package differences between the substitute parts?

A: Both substitute parts use TO-220-3 Full Pack through-hole packaging. The VF30150C-E3/4W features an isolated tab variant (ITO-220AB), which provides electrical isolation of the tab from the case. The STPS30150CFP uses standard TO-220FP packaging. Both are mechanically compatible with through-hole PCB layouts designed for the original MBRF30H150CTH.

Q: What is the significance of the isolated tab in the VF30150C-E3/4W?

A: The isolated tab (ITO-220AB) in the VF30150C-E3/4W provides electrical isolation between the mounting tab and the device case. This feature is beneficial in applications where the tab is mounted to a heat sink that must remain electrically isolated from the circuit. The standard TO-220FP package in STPS30150CFP does not provide this isolation.

Q: How do reverse leakage currents compare across the three parts?

A: The MBRF30H150CTH specifies 60 µA reverse leakage at 150 V. The STPS30150CFP exhibits 6.5 µA at 150 V, representing significantly lower leakage. The VF30150C-E3/4W exhibits 200 µA at 150 V, representing higher leakage. Reverse leakage affects standby power consumption and circuit performance in high-impedance applications.

Q: What compliance certifications apply to all three parts?

A: All three parts carry ROHS3 compliance and REACH unaffected designation. These certifications confirm compliance with hazardous substance restrictions and environmental regulations applicable to electronic components.

Q: Why is the MBRF30H150CTH classified as obsolete?

A: The MBRF30H150CTH is listed as obsolete product status by onsemi. Substitute parts with active product status from STMicroelectronics and Vishay provide continued availability and long-term supply assurance for applications requiring 150 V, 15 A Schottky diode arrays in TO-220-3 Full Pack configurations.
