MBR10150CTP Equivalent & Substitute Parts

Part Overview

The MBR10150CTP is a Schottky diode array manufactured by Diodes Incorporated, configured as a 1 Pair Common Cathode rectifier with 150 V reverse voltage rating and 5 A average rectified current per diode. The device is packaged in a TO-220-3 Isolated Tab through-hole configuration and is currently classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR10150CTP is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Mounting Type: Through Hole
• Package Category: TO-220-3 form factor

Secondary Compatibility Factors:

• Current - Average Rectified (Io) (per Diode): Equal or greater rating
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Substitute parts identified in this reference maintain the core electrical specifications (150 V reverse voltage, Schottky technology, common cathode configuration) and through-hole TO-220-3 mounting. Variations in current rating, forward voltage, and reverse leakage current are documented to enable informed selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

STPS10150CT (STMicroelectronics) is the direct electrical equivalent for applications requiring exact current and voltage specifications. This part maintains 5 A average rectified current per diode and 150 V reverse voltage rating identical to the MBR10150CTP. The STPS10150CT is currently in active production status, ensuring long-term availability. Forward voltage characteristics are comparable (920 mV @ 5 A versus 910 mV @ 5 A), with superior reverse leakage performance (2 µA @ 150 V). This part is suitable for direct replacement in existing designs without circuit modification.

DSTF30150C (Littelfuse) and DSTF40150C (Littelfuse) are higher-current variants rated at 15 A and 20 A respectively. These parts maintain the 150 V reverse voltage specification and Schottky technology. Both are in active production status. These substitutes are applicable in designs where the original 5 A rating provides insufficient margin or where higher current capacity is required. Forward voltage increases proportionally with current rating (1.36 V @ 15 A and 1.43 V @ 20 A), which must be evaluated against circuit thermal and voltage drop requirements. Maximum junction temperature is reduced to 150°C compared to the MBR10150CTP specification of 175°C.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and through-hole TO-220-3 mounting compatibility. Selection between direct equivalence (STPS10150CT) and higher-current alternatives (DSTF30150C, DSTF40150C) depends on application current requirements and thermal design constraints.

Frequently Asked Questions (FAQ)

Q: Can STPS10150CT be used as a direct replacement for MBR10150CTP?

A: Yes. The STPS10150CT maintains identical electrical specifications for diode configuration, reverse voltage (150 V), average rectified current (5 A per diode), and fast recovery speed. Both are Schottky technology, 1 Pair Common Cathode configuration in TO-220-3 through-hole packages. The STPS10150CT is in active production status, addressing the obsolescence of the MBR10150CTP.

Q: What are the differences between STPS10150CT and the higher-current Littelfuse alternatives?

A: STPS10150CT maintains the 5 A current rating of the original MBR10150CTP. DSTF30150C is rated for 15 A and DSTF40150C for 20 A per diode. All three maintain 150 V reverse voltage. Forward voltage increases with current rating: 920 mV @ 5 A (STPS10150CT), 1.36 V @ 15 A (DSTF30150C), and 1.43 V @ 20 A (DSTF40150C). Maximum junction temperature for Littelfuse parts is 150°C versus 175°C for STPS10150CT and MBR10150CTP.

Q: Are package dimensions compatible between all substitute parts?

A: All substitute parts use TO-220-3 through-hole mounting. MBR10150CTP and DSTF30150C/DSTF40150C feature isolated tab configurations, while STPS10150CT uses standard TO-220-3 packaging. Isolated tab variants provide electrical isolation between the tab and the diode cathode, which may be required in specific circuit designs. Verify isolated tab requirement before selecting STPS10150CT as a replacement for MBR10150CTP in applications dependent on tab isolation.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. MBR10150CTP, STPS10150CT, DSTF30150C, and DSTF40150C are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring 5 A current capacity at 150 V, STPS10150CT is recommended due to active production status and direct electrical equivalence. For applications requiring higher current capacity, DSTF30150C (15 A) or DSTF40150C (20 A) are suitable alternatives, provided circuit design accommodates the increased forward voltage drop and reduced maximum junction temperature.

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

A: MBR10150CTP specifies 50 µA @ 150 V reverse leakage. STPS10150CT exhibits superior performance at 2 µA @ 150 V. DSTF30150C and DSTF40150C specify 200 µA and 250 µA respectively. Higher reverse leakage increases standby power dissipation and may affect circuit performance in low-power or precision applications. STPS10150CT provides the lowest reverse leakage among available substitutes.
