Product details
Overview
MBRB10100CT-13 from Diodes Incorporated is a 10A dual common-cathode Schottky barrier rectifier in TO263AB (D2PAK) package, rated for 100V peak reverse voltage, with max 0.84V forward voltage at 5A/25°C and 0.1mA leakage at 100V/25°C. It serves as polarity protection and freewheeling diode in DC-DC converters and industrial power supplies.
For engineers reviewing the MBRB10100CT-13 datasheet, MBRB10100CT-13 pinout, MBRB10100CT-13 application, or MBRB10100CT-13 equivalent, key selection criteria include per-leg 5A average current rating, thermal resistance of 5°C/W junction-to-case, AEC-Q101 qualification, RoHS/Green compliance, and TO263AB mechanical footprint compatibility.
Technical Context
This dual Schottky rectifier integrates two independent 5A legs sharing a common cathode terminal, enabling synchronous rectification or dual-rail output protection in compact high-current layouts. Its guard ring die construction enhances transient immunity, while low VF minimizes conduction loss in 12V–48V input systems.
Rated for -55°C to +175°C operation and qualified to AEC-Q101, it supports automotive under-hood and industrial motor drive applications where thermal cycling and surge robustness are critical. The 110A non-repetitive surge rating (8.3ms half-sine) enables reliable handling of inductive kickback in relay and solenoid drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in 48V bus clamp or flyback snubber circuits. |
| IO (per leg) | 5 A - Continuous average forward current per anode leg at TA=25°C; derates to ~3.5A at 100°C ambient per Figure 4. |
| VF (max) | 0.84 V @ 5A, 25°C - Low conduction loss ensures <4.2W dissipation per leg at full load, reducing heatsink requirements. |
| IR (max) | 0.1 mA @ 100V, 25°C - Minimal leakage preserves efficiency in battery-backed or standby power paths. |
| RθJC | 5 °C/W - Enables direct PCB copper pour thermal coupling; 25°C temperature rise per 5W dissipated into case. |
| IFSM | 110 A - Withstands single 8.3ms inductive surges typical in motor commutation or relay de-energization. |
| TJ Range | -55°C to +175°C - Supports operation in engine control units, solar inverters, and industrial PLCs without derating. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS10100CT | Same 100V/10A rating, but VF = 0.85V @ 5A/25°C; RθJC = 6°C/W; no AEC-Q101 qualification. | Qualified for industrial but not automotive use; lacks transient-rated guard ring structure. | Select when cost sensitivity outweighs automotive qualification and surge margin. |
| VB10100C-E3/4W | VF = 0.78V @ 5A/25°C; IO = 5A/leg; RθJC = 4.5°C/W; AEC-Q101 qualified; TO263AB package. | Lower VF improves efficiency in thermally constrained designs; identical footprint enables drop-in replacement. | Prefer for new designs targeting >95% efficiency in space-constrained 48V telecom rectifiers. |
Compared with STPS10100CT, MBRB10100CT-13 offers superior surge robustness and automotive qualification; versus VB10100C-E3/4W, it trades 0.06V higher VF for broader distributor availability and proven field reliability in motor drives.

FAQ
What is the maximum continuous current per leg at 100°C ambient?
Per Figure 4, the average forward current derates linearly from 5A at 25°C to approximately 3.5A at 100°C ambient when mounted on a 2-inch aluminum board. This reflects thermal limits imposed by RθJA = 20°C/W and junction temperature cap of 175°C.
Is the cathode tab electrically isolated from the PCB ground plane?
No-the cathode (Pin 3) is the exposed metal tab and must be soldered directly to a PCB copper pour designated as the system output ground or common return. It is not insulated; isolation requires a thermal pad with dielectric layer, which increases RθJC by ≥3°C/W.
Does MBRB10100CT-13 support reflow soldering per J-STD-020?
Yes-it is rated for moisture sensitivity level 1 (MSL-1), meaning unlimited floor life and compatibility with standard Pb-free reflow profiles (peak 260°C, 30 sec max). Matte tin annealed terminals ensure reliable wetting without voiding.
How does the guard ring construction improve reliability in automotive environments?
The integrated guard ring mitigates edge breakdown during load dump transients (ISO 7637-2 Pulse 5a), reducing failure rate in alternator-regulated 12V systems. It enables sustained operation at 100V reverse bias without parametric shift after 1000 cycles of 120V/50ms surge testing.
