Product details
Overview
MBR10100CT-Y from Taiwan Semiconductor is a 10A, 100V dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.95V max forward voltage at 10A/25°C, 120A surge capability, and 1.5°C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in DC–DC converters and offline SMPS secondary-side circuits.
For engineers reviewing the MBR10100CT-Y datasheet, MBR10100CT-Y pinout, MBR10100CT-Y application, or MBR10100CT-Y equivalent, key selection factors include repetitive peak reverse voltage (100 V), forward voltage at rated current, thermal resistance, surge current rating, and dual-common-cathode configuration for center-tapped transformer designs.
Technical Context
This dual-die Schottky rectifier integrates two independent 10A anodes sharing a common cathode terminal, enabling full-wave rectification without external diode pairing. Its low VF and fast recovery support high-frequency switching up to 20 kHz with minimal conduction loss.
The device operates across –55°C to +150°C junction temperature range, with 10,000 V/μs critical dv/dt rating ensuring robustness against voltage transients in inductive loads and flyback topologies.

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-MBR10100CT | Same 100 V VRRM, 10 A IF, TO-220AB; VF = 0.92 V max @ 10 A/25°C (slightly lower conduction loss) | Identical dual-common-cathode configuration; validated in same SMPS reference designs | Preferred where marginal VF reduction improves thermal margin in space-constrained adapters |
| ON Semiconductor MBR10100CT | Same ratings and package; IR = 3 mA max @ 100 V/125°C (higher leakage than MBR10100CT-Y's 2 mA) | Used in automotive infotainment power supplies requiring extended temp validation | Consider only if legacy qualification data exists; otherwise MBR10100CT-Y offers tighter leakage spec |
Compared with VS-MBR10100CT and MBR10100CT, the MBR10100CT-Y delivers the lowest reverse leakage at high temperature (2 mA vs. ≥3 mA), making it preferable for thermally demanding, low-standby-power applications where leakage-induced losses must be minimized.

FAQ
What is the maximum junction temperature rating for MBR10100CT-Y?
The MBR10100CT-Y has a maximum junction temperature (TJ) of +150°C, with operational range from –55°C to +150°C. This rating allows reliable use in enclosed power supplies and industrial environments where ambient temperatures exceed 70°C, provided thermal design maintains junction temperature within limits using the specified 1.5°C/W RθJC.
Does MBR10100CT-Y support full-wave rectification without external components?
Yes, the MBR10100CT-Y integrates two Schottky diodes with a common cathode in a single TO-220AB package, enabling full-wave rectification from a center-tapped transformer or dual-input source. No external diode pairing or additional interconnects are required-Pin 1 and Pin 3 serve as independent anodes, while Pin 2 is the shared cathode output.
What is the forward voltage specification for MBR10100CT-Y at 10 A and 125°C?
At 10 A forward current and 125°C junction temperature, the MBR10100CT-Y exhibits a maximum forward voltage (VF) of 0.85 V. This value is confirmed in the Electrical Specifications table and reflects reduced conduction loss at elevated temperature due to Schottky physics, aiding thermal stability in high-load conditions.
Is MBR10100CT-Y halogen-free and RoHS compliant?
Yes, the MBR10100CT-Y is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound and plating meet environmental standards for consumer, industrial, and computing applications, with matte tin-plated leads qualified per J-STD-002 for solderability and JESD 201 Class 1A for whisker resistance.
What is the repetitive peak reverse voltage (VRRM) of MBR10100CT-Y?
The repetitive peak reverse voltage (VRRM) of MBR10100CT-Y is 100 V per diode. This rating is explicitly defined in the Absolute Maximum Ratings table and applies individually to each anode–cathode path, allowing safe operation in 48 V and 60 V nominal bus applications with appropriate derating margins.
