Product details
Overview
MBRS15100CT-Y from Taiwan Semiconductor is a 15A, 100V dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, featuring 0.92V forward voltage at 7.5A/25°C and 0.82V at 7.5A/125°C, with 150A surge capability and guard ring overvoltage protection - used in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the MBRS15100CT-Y datasheet, MBRS15100CT-Y pinout, MBRS15100CT-Y application, or MBRS15100CT-Y equivalent, key selection criteria include reverse voltage rating (100V), thermal resistance (RθJC = 2°C/W), junction temperature range (–55°C to +150°C), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 100V/15A diodes in a single TO-263AB thermally optimized package. Its low VF and high IFSM support high-frequency switching topologies where conduction loss and thermal management are critical.
The device uses guard ring technology to enhance ruggedness against transient overvoltage, and its JESD201 Class 1A whisker-resistant matte tin plating ensures long-term solder joint reliability in automated SMT assembly.
Key Specifications

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-15CTH10-M3/45 | Same 100V VRRM, 15A IF, but TO-220AC package; higher RθJA (65°C/W) and no guard ring | Requires heatsink mounting; unsuitable for space-constrained SMT-only designs | Choose when through-hole assembly or legacy board compatibility is required |
| ON Semiconductor MBRS15100CT | Identical electrical specs and TO-263AB package, but non-Y suffix (no halogen-free guarantee or MSL Level 1 confirmation) | Lacks documented halogen-free compliance and J-STD-020 Level 1 rating | Acceptable for cost-sensitive non-regulated commercial use; MBRS15100CT-Y preferred for medical/industrial BOMs |

FAQ
What is the maximum junction temperature rating for MBRS15100CT-Y?
The MBRS15100CT-Y has a maximum junction temperature (TJ) of +150°C, with a full operating range from –55°C to +150°C. This rating enables reliable operation in sealed industrial enclosures and high-ambient automotive ECU environments. Derating curves in the official datasheet confirm sustained 15A conduction up to 125°C case temperature when properly heatsunk. The device's RθJC of 2°C/W supports effective thermal transfer to external copper or heatsinks.
Does MBRS15100CT-Y have a guard ring structure?
Yes, MBRS15100CT-Y incorporates a guard ring design explicitly stated in its features list to provide overvoltage protection. This structure enhances edge termination robustness, improving resistance to avalanche breakdown during transient voltage events such as load dumps or inductive switching spikes. It contributes directly to the device's rated 150A surge capability and supports compliance with industrial surge immunity standards like IEC 61000-4-5.
What is the forward voltage of MBRS15100CT-Y at 15A and 25°C?
The datasheet does not specify VF at 15A and 25°C for MBRS15100CT-Y - only at 7.5A (0.92V). However, typical VF at 15A/25°C for comparable 100V Schottky rectifiers in this family falls between 0.98V and 1.05V. For precise design validation, engineers should consult the "Typical Forward Characteristics" curve (Fig.4) in the official MBRS15xxCT-Y datasheet, which plots VF across current and temperature for all variants including MBRS15100CT-Y.
Is MBRS15100CT-Y RoHS and halogen-free compliant?
Yes, MBRS15100CT-Y is both RoHS compliant and halogen-free per IEC 61249-2-21. These compliance statements appear in the official Taiwan Semiconductor documentation under FEATURES and ORDERING INFORMATION sections. The "-Y" suffix denotes halogen-free molding compound and RoHS-compliant finish, distinguishing it from non-suffix or "-CT" variants that may lack formal halogen-free certification.
What is the moisture sensitivity level (MSL) of MBRS15100CT-Y?
MBRS15100CT-Y is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can be processed using standard reflow profiles without dry packing or baking. This is confirmed in the MECHANICAL DATA section of the datasheet and reflects the device's robust packaging and moisture barrier properties - a key advantage for high-throughput SMT lines and just-in-time manufacturing workflows.
