Product details
Overview
MBRS1590CTH from Taiwan Semiconductor is a 15A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 90V repetitive peak reverse voltage (VRRM), 150A surge current (IFSM), and maximum junction temperature of 150°C. It serves as a high-efficiency freewheeling or reverse-battery protection diode in automotive DC/DC converters.
For engineers reviewing the MBRS1590CTH datasheet, MBRS1590CTH pinout, MBRS1590CTH application, or MBRS1590CTH equivalent, key selection criteria include its 90V VRRM, 0.92V typical forward voltage at 7.5A/25°C, AEC-Q101 qualification, TO-263AB thermal performance (RθJC = 2°C/W), and moisture sensitivity level 1 compliance.
Technical Context
This dual-die Schottky rectifier integrates two independent anode-cathode junctions in a single TO-263AB thermally enhanced surface-mount package. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads ensure reliable solderability per J-STD-002.
The device operates across -55°C to +150°C junction temperature range with 50°C/W junction-to-ambient thermal resistance. It delivers low conduction loss (VF ≤ 0.92V @ 7.5A, 25°C) and high dv/dt capability (10,000 V/μs), making it suitable for high-frequency switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in reverse-biased applications like reverse battery protection. |
| IF | 15 A - Continuous average forward current per diode; supports high-current DC/DC output stages without forced air cooling. |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in automotive power systems. |
| VF (typ) | 0.92 V @ 7.5A, 25°C - Low forward drop reduces conduction losses and improves system efficiency in low-voltage, high-current paths. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; enables direct heatsinking via the exposed tab for high-power dissipation management. |
| TJ max | 150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive environments. |
| MSL | Level 1 (J-STD-020) - No floor life limitation; compatible with standard SMT reflow without dry-pack or baking requirements. |
Pinout & Package
Package: TO-263AB (D2PAK) - thermally optimized surface-mount package with exposed metal tab for direct heatsinking and high-current handling. Dimensions comply with JEDEC MO-211 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Anode of first Schottky diode | Connects to input/high-side node in freewheeling or reverse polarity protection configuration. |

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-MBR1590CT | Same 90V VRRM, 15A IF, TO-263AB package; VF = 0.89V @ 7.5A (25°C); no AEC-Q101 claim in datasheet. | Not certified for automotive under-hood use; suitable for industrial/commercial DC/DC where qualification is not mandated. | Select if AEC-Q101 is not required and lower VF is prioritized over automotive qualification. |
| ON Semiconductor MBR1590CT | Identical ratings (90V, 15A, TO-263AB); VF = 0.90V @ 7.5A (25°C); AEC-Q101 qualified per revision 1.0 datasheet. | Direct functional match with same automotive qualification scope; minor packaging marking variation only. | Preferred for second-source assurance in AEC-Q101-compliant designs where Taiwan Semiconductor supply continuity is constrained. |

FAQ
What is the maximum junction temperature rating for MBRS1590CTH?
The MBRS1590CTH has a maximum junction temperature (TJ) rating of +150°C, validated across its full operating range from -55°C to +150°C. This rating enables deployment in under-hood automotive environments where ambient temperatures exceed 105°C. The device maintains specified electrical performance up to this limit, supported by its 2°C/W junction-to-case thermal resistance. Thermal design must ensure actual TJ remains below 150°C under worst-case power dissipation conditions.
Is MBRS1590CTH pin-compatible with other parts in the MBRS15xxCTH family?
Yes, all MBRS15xxCTH devices-including MBRS1535CTH, MBRS1560CTH, and MBRS15150CTH-share identical TO-263AB (D2PAK) package dimensions, pinout, and terminal assignments. The only differences are VRRM ratings (35V to 150V) and corresponding forward voltage characteristics. This uniformity allows board-level voltage scalability without layout changes, provided thermal and surge margins are verified for each variant.
Does MBRS1590CTH require special handling during PCB assembly?
No, MBRS1590CTH is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry-packaging or baking prior to reflow soldering. Standard lead-free reflow profiles (e.g., IPC/JEDEC J-STD-020D) apply. The matte tin-plated leads meet J-STD-002 for solderability, and the package complies with JEDEC MO-211 mechanical standards for automated placement.
What is the reverse leakage current specification for MBRS1590CTH at 125°C?
At 125°C junction temperature and rated 90V reverse voltage, the MBRS1590CTH exhibits a maximum reverse leakage current (IR) of 5 mA per diode, as specified in the Electrical Specifications table. This value reflects worst-case behavior under high-temperature stress and is critical for low-power standby circuits where leakage could impact quiescent current budgets.
How does the guard ring feature improve reliability in MBRS1590CTH?
The guard ring in MBRS1590CTH enhances edge termination robustness, suppressing premature avalanche breakdown at the silicon periphery during voltage transients. This structural feature increases the device's ability to withstand repetitive overvoltage events-such as load dump spikes in automotive systems-without degradation. It directly contributes to the device's AEC-Q101 qualification by improving ruggedness beyond standard Schottky designs.
