Product details
Overview
MBRS3045CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 30A average forward current, 45V repetitive peak reverse voltage, and 220A non-repetitive surge current; it delivers low forward voltage (0.70 V at 15 A, 25°C) and supports automotive-grade reliability per AEC-Q101.
For engineers reviewing the MBRS3045CTH datasheet, MBRS3045CTH pinout, MBRS3045CTH application, or MBRS3045CTH equivalent, key selection criteria include thermal resistance (RθJC = 1.5°C/W), junction temperature range (–55°C to +150°C), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance for automotive and industrial power conversion designs.
Technical Context
The MBRS3045CTH integrates two independent Schottky diodes in a common-cathode configuration within a single TO-263AB thermally enhanced surface-mount package. Its low VF and high IFSM support high-efficiency DC/DC conversion and freewheeling in switching topologies operating up to 150°C junction temperature.
Designed with guard ring structure for overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability, the device meets AEC-Q101 stress testing requirements including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress test - confirming suitability for under-hood automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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-30CPH045 | Same TO-263AB package, 30 A/45 V, but higher VF (0.82 V @ 30 A, 25°C) and no AEC-Q101 qualification | Targeted at industrial rather than automotive use; lacks guard ring and automotive stress validation | Acceptable for cost-sensitive non-automotive DC/DC where AEC-Q101 is not mandated |
| ON Semiconductor MBR3045CT | Identical electrical ratings and TO-263AB package; however, only offered in tape-and-reel with different marking (MBR3045CT), and not AEC-Q101 qualified | Used in consumer and industrial power supplies; lacks automotive reliability documentation and J-STD-020 Level 1 MSL | Valid alternative if automotive qualification and moisture sensitivity are not required |
Compared with VS-30CPH045 and MBR3045CT, the MBRS3045CTH uniquely combines AEC-Q101 qualification, J-STD-020 Level 1 handling, and guard ring protection - making it the only choice for automotive-grade 45 V Schottky rectification where reliability under transient stress and assembly robustness are mandatory.

FAQ
What is the maximum junction temperature rating for MBRS3045CTH?
The MBRS3045CTH has a maximum junction temperature (TJMAX) of +150°C, verified per AEC-Q101 thermal stress testing. This allows sustained operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design achieves RθJA ≤ 50°C/W. The MBRS3045CTH datasheet specifies derating curves confirming usable current down to 0 A at 150°C case temperature.
Is MBRS3045CTH pin-compatible with MBR3045CT?
Yes, MBRS3045CTH and MBR3045CT share identical TO-263AB (D2PAK) mechanical dimensions, pinout, and terminal configuration - both feature dual anodes and a common cathode. However, MBRS3045CTH adds AEC-Q101 qualification, J-STD-020 Level 1 moisture sensitivity, and guard ring protection not present in MBR3045CT, so direct substitution requires validation of automotive reliability requirements.
Does MBRS3045CTH support reverse battery protection in automotive systems?
Yes, MBRS3045CTH is routinely used for reverse battery protection due to its 45 V VRRM, low forward voltage (0.70 V at 15 A), and AEC-Q101 qualification. When placed in series with the battery input, it blocks reverse polarity while minimizing voltage drop and power loss - critical for 12 V/24 V vehicle networks where even 0.1 V excess drop impacts cold-cranking performance. The MBRS3045CTH guard ring further enhances survivability during polarity reversal transients.
What is the thermal resistance from junction to case (RθJC) for MBRS3045CTH?
The MBRS3045CTH has a typical junction-to-case thermal resistance (RθJC) of 1.5°C/W, measured from die to the exposed cathode tab. This value enables effective heat transfer to a PCB copper pour or external heatsink, supporting full 30 A current capability without active cooling when mounted on ≥2 oz copper with ≥4 cm² thermal pad area. The MBRS3045CTH datasheet confirms this via transient thermal impedance curves.
Is MBRS3045CTH halogen-free and RoHS compliant?
Yes, MBRS3045CTH is both RoHS compliant and halogen-free per IEC 61249-2-21, using molding compound and plating materials that meet strict automotive environmental standards. This compliance is documented in TSC's material declarations and verified through third-party testing. The MBRS3045CTH marking includes "G" to indicate green compound, and all manufacturing lots undergo periodic audit for halogen content and restricted substance limits.
