Product details
Overview
MBR10100CT-G1 from Diodes Incorporated is a 10A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 100V peak reverse voltage, with max 0.84V forward voltage at 5A/25°C and 0.05mA reverse leakage at 100V/25°C; used for polarity protection and recirculating diode functions in DC power supplies and motor drive circuits.
For engineers reviewing the MBR10100CT-G1 datasheet, MBR10100CT-G1 pinout, MBR10100CT-G1 application, or MBR10100CT-G1 equivalent, key selection criteria include per-leg 5A average forward current rating, thermal resistance of 4°C/W (junction-to-case), dual common-cathode configuration, RoHS-compliant matte tin finish, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual-diode Schottky rectifier integrates two independent 5A-rated anode terminals sharing a single cathode terminal, enabling synchronous half-wave rectification or bidirectional clamp operation. Its guard ring die construction provides transient overvoltage immunity, while low VF minimizes conduction loss in high-frequency switching converters.
The device operates across –55°C to +175°C junction temperature range and supports 110A non-repetitive surge current (8.3ms half-sine). Thermal performance depends on heatsink mounting: RθJC = 4°C/W (TO-220AB) requires mechanical attachment to external heatsink for sustained 10A total current handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in unidirectional DC bus applications. |
| IO (per leg) | 5 A - Continuous average forward current per anode; total device rating is 10A with shared cathode path. |
| VF (max) | 0.84 V @ 5A, 25°C - Low conduction loss enables >92% efficiency in 12V–48V SMPS output stages. |
| IR (max) | 0.05 mA @ 100V, 25°C - Minimal leakage preserves battery hold-up time in always-on systems. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance; mandates heatsink use for >3W continuous dissipation. |
| IFSM | 110 A - Peak surge capability handles inrush currents during hot-plug events or motor startup. |
| Operating TJ | –55°C to +175°C - Wide temperature range supports under-hood automotive and industrial motor control environments. |
Pinout & Package
Package: TO-220AB - Molded plastic case with integral metal tab (cathode-connected), UL 94V-0 rated, 1.95g weight, lead-free matte tin annealed finish over copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first diode leg | Accepts positive input for independent rectification path; electrically isolated from Anode 2. |

| Anode 2 (Lead 3) | Input terminal for second diode leg | Enables dual-input/single-output topology; supports dual-rail or redundant supply configurations. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| DC Power Supply Output Rectification | Polarity Protection Circuit |
|---|---|
Use Scenario: Secondary-side rectification in 24V/48V offline AC-DC adapters and telecom power modules. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier replacing center-tapped transformer + single diode; reduces conduction loss vs. fast recovery diodes. Use Value: 0.84V VF at 5A cuts power loss by ~40% versus 1.2V Si diodes, lowering heatsink size and improving system efficiency to >90%. | Use Scenario: Reverse-voltage protection at input of industrial PLC I/O modules and embedded controllers. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-load; blocks reverse current during battery swap or hot-swap events. Use Value: 0.05mA IR at 100V prevents standby drain in always-on systems; dual-leg layout allows redundancy or split-bus isolation. |
| Motor Drive Freewheeling Diode | Automotive Body Control Module |

Use Value: AEC-Q101 qualification and guard ring design meet ISO 7637-2 pulse 5a/b immunity requirements for load dump protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS10H100CG | Same 100V/10A rating, but TO-220AC package with isolated tab; RθJC = 5°C/W; VF = 0.82V @ 5A. | Tab isolation eliminates need for insulating washer; preferred where heatsink is grounded. | Select when electrical isolation of cathode tab is required; verify footprint compatibility (TO-220AC vs TO-220AB). |
| Vishay VS-MBR10100CT | Identical specs and TO-220AB package; same VF, IR, and thermal resistance; RoHS-compliant matte tin finish. | No functional difference; dual-source option for supply chain diversification. | Drop-in replacement with identical mechanical and electrical behavior; validated for same AEC-Q101 stress tests. |
Compared with STPS10H100CG, MBR10100CT-G1 offers lower RθJC (4 vs 5°C/W) but requires insulating hardware; versus VS-MBR10100CT, it shares identical performance and footprint-making it a direct second-source alternative for automotive BOM resilience.

FAQ
What is the cathode connection method in MBR10100CT-G1?
The cathode is internally connected to the metal tab and lead 2. The tab is electrically active and must be electrically isolated from the heatsink using mica or polymer washers unless the heatsink is floating. This configuration enables efficient thermal transfer while maintaining circuit-level cathode reference integrity.
Can MBR10100CT-G1 operate at full 10A total current continuously?
No-its 10A rating is the sum of two 5A legs, but continuous operation at full 10A requires forced-air cooling or a large heatsink. At 25°C ambient with standard 45mm × 20mm × 12mm heatsink, derating curves limit usable current to ~6.5A total to maintain TJ ≤ 125°C per Figure 4.
Is MBR10100CT-G1 suitable for synchronous rectification?
No-it is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier controller or driver. It lacks gate drive interface or timing logic; its role is fixed-function uncontrolled conduction, making it appropriate for flyback/freewheeling but not for actively switched topologies requiring gate signals.
Does MBR10100CT-G1 require derating for capacitive loads?
Yes-per datasheet note, average forward current must be reduced by 20% when used with capacitive-input filters due to higher peak currents. For example, 5A per leg becomes 4A maximum under such conditions to prevent thermal runaway and ensure reliability over lifetime.
