Taiwan Semiconductor Corporation MBRS15100CTH

Overview

MBRS15100CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 15 A average forward current, 100 V repetitive peak reverse voltage, and 150 A surge current. It delivers low forward voltage (0.92 V at 7.5 A, 25°C), operates up to 150°C junction temperature, and is AEC-Q101 qualified for automotive power conversion.

For engineers reviewing the MBRS15100CTH datasheet, MBRS15100CTH pinout, MBRS15100CTH application, or MBRS15100CTH equivalent, key selection criteria include its 100 V V_RRM, dual-common-cathode configuration, 2 °C/W junction-to-case thermal resistance, and suitability for high-frequency DC/DC converters requiring low conduction loss and robust surge handling.

Technical Context

This dual-die Schottky rectifier integrates two independent anodes sharing a common cathode terminal, enabling half-wave or dual-output rectification in compact layouts. Its guard ring structure provides overvoltage protection, while the matte tin-plated leads ensure reliable solderability per J-STD-002.

Designed for operation up to 150°C, it exhibits 5 mA max reverse leakage at 100 V and 125°C, and maintains stable forward voltage across temperature-0.82 V typ at 7.5 A and 125°C-supporting thermally demanding automotive and industrial environments.

FAQ

What is the maximum junction temperature rating for MBRS15100CTH?

The MBRS15100CTH has a maximum junction temperature (T_J) rating of +150°C, verified per AEC-Q101 stress testing. This allows continuous operation in high-ambient environments such as engine compartments or sealed ECUs. Derating curves confirm usable current capacity down to 110°C case temperature at full 15 A rating. Thermal design must maintain R_θJA ≤ 50°C/W with adequate PCB copper area or heatsinking to avoid exceeding this limit in MBRS15100CTH applications.

Is MBRS15100CTH pin-compatible with other parts in the MBRS15xxCTH family?

Yes, all MBRS15xxCTH variants-including MBRS1535CTH through MBRS15150CTH-share identical TO-263AB (D2PAK) mechanical outline, pin assignment (Anode A / Anode B / Common Cathode), and thermal pad configuration. The only differences are V_RRM ratings and corresponding forward voltage characteristics; thus, MBRS15100CTH can be substituted within the same footprint for 100 V system requirements without layout changes.

Does MBRS15100CTH support automated SMT placement?

Yes, MBRS15100CTH is designed for automated surface-mount placement per J-STD-020 moisture sensitivity level 1, requiring no pre-bake. Its TO-263AB package features coplanar matte tin-plated leads compliant with J-STD-002 solderability standards, and the marking code "MBRS15100CT" is laser-etched for machine vision recognition. Reflow profiles must respect peak temperature limits defined in the TSC datasheet to preserve the Schottky junction integrity in MBRS15100CTH.

What is the reverse leakage current specification for MBRS15100CTH at elevated temperature?

At 100 V reverse voltage and 125°C junction temperature, MBRS15100CTH specifies a maximum reverse leakage current (I_R) of 5 mA. At 25°C and rated V_RRM, leakage is limited to 100 µA. This low, well-characterized leakage supports stable operation in always-on automotive modules where standby power budget is constrained, and confirms robustness of the Schottky barrier under thermal stress-key for MBRS15100CTH reliability validation.

How does the guard ring feature improve reliability in MBRS15100CTH?

The integrated guard ring in MBRS15100CTH mitigates edge breakdown during voltage transients-such as load dump or ISO 7637-2 pulses-by distributing electric field stress away from the active junction periphery. This structural enhancement increases ruggedness without external components, directly supporting AEC-Q101 transient overvoltage test compliance. In real-world MBRS15100CTH deployments, it extends lifetime in 12 V/24 V systems exposed to harsh automotive electrical environments.
