Product details
Overview
MBR15100CT-Y from Taiwan Semiconductor is a 15A, 100V dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.92V forward voltage at 7.5A/25°C, 150A surge capability, and junction-to-case thermal resistance of 1.5°C/W. It serves as a high-efficiency output rectifier in DC-DC converters and switching power supplies where low conduction loss and fast recovery are critical.
For engineers reviewing the MBR15100CT-Y datasheet, MBR15100CT-Y pinout, MBR15100CT-Y application, or MBR15100CT-Y equivalent, key selection factors include its 100V VRRM rating, dual-common-cathode configuration, TO-220AB mechanical mounting, and 5µA reverse leakage at 125°C - all verified in Taiwan Semiconductor's D2104 specification document.
Technical Context
This device integrates two independent Schottky diodes in a single TO-220AB package with common cathode connection (CT), enabling synchronous or parallel rectification in center-tapped or dual-output topologies. Its 10,000 V/μs dv/dt rating supports operation in high-frequency SMPS designs up to several hundred kHz.
The MBR15100CT-Y operates across -55°C to +150°C junction temperature range, with thermal performance defined by RθJC = 1.5°C/W and RθJA = 10°C/W (free air). Its 1.88g mass and matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 1A whisker requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MBR15100CT | Same 15A/100V rating, TO-220AB package, but VF = 0.89V @ 7.5A/25°C; RθJC = 1.4°C/W | Slightly lower conduction loss; identical pinout and mounting | Preferred where marginal thermal margin exists and sub-30mV VF reduction justifies sourcing change |
| ON Semiconductor MBR15100CT | Identical electrical specs and TO-220AB mechanical outline; RoHS-compliant but halogen status unspecified | No functional difference in circuit operation or layout | Drop-in alternative when Taiwan Semiconductor supply is constrained; verify date-code and packaging compatibility |

FAQ
What is the maximum junction temperature rating for MBR15100CT-Y?
The MBR15100CT-Y has a maximum junction temperature (TJ) of +150°C, validated per Taiwan Semiconductor's D2104 specification. This rating allows sustained operation in high-ambient environments when mounted with proper heatsinking and within its thermal resistance limits (RθJC = 1.5°C/W). Derating curves in the datasheet define safe current limits above 25°C ambient.
Does MBR15100CT-Y have a common-cathode or common-anode configuration?
The MBR15100CT-Y uses a common-cathode (CT) configuration: Pin 2 (center lead) and the metal tab are internally connected to the shared cathode of both Schottky diodes. Pins 1 and 3 serve as independent anodes. This configuration is confirmed in the marking diagram and absolute maximum ratings table of the D2104 datasheet.
What is the forward voltage of MBR15100CT-Y at full rated current and elevated temperature?
At 15A and 125°C junction temperature, the MBR15100CT-Y forward voltage is not explicitly specified in the datasheet; however, at 7.5A and 125°C, it is 0.82V (typical). The device's VF increases with current and decreases with temperature - the 0.92V value at 7.5A/25°C reflects room-temperature conduction loss for thermal modeling.
Is MBR15100CT-Y halogen-free and RoHS compliant?
Yes, the MBR15100CT-Y is both RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the D2104 datasheet. The molding compound and plating meet these environmental standards, making it suitable for regulated consumer and industrial end equipment.
What is the reverse leakage current of MBR15100CT-Y at maximum rated voltage and temperature?
At VR = 100V and TJ = 125°C, the MBR15100CT-Y exhibits a maximum reverse leakage current (IR) of 5 µA per diode, as specified in the ELECTRICAL SPECIFICATIONS table. This low leakage supports high efficiency in standby and light-load conditions typical of modern energy-efficient power supplies.
