Product details
Overview
MBR30100CT-Y from Taiwan Semiconductor is a 30A, 100V dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.84V max forward voltage at 15A/25°C and 0.94V at 30A/25°C, with 7.5mA reverse leakage at 125°C and 1.5°C/W junction-to-case thermal resistance - used in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the MBR30100CT-Y datasheet, MBR30100CT-Y pinout, MBR30100CT-Y application, or MBR30100CT-Y equivalent, key selection criteria include rated VRRM (100V), IFSM (200A), TJ max (150°C), thermal resistance (1.5°C/W), and dual-diode configuration for center-tapped or full-wave bridge topologies.
Technical Context
This dual-die Schottky rectifier integrates two independent anode-cathode junctions in a single TO-220AB package with common cathode connection (CT), enabling full-wave rectification without external wiring. Its low VF and fast switching eliminate minority-carrier recovery losses, making it suitable for high-frequency (>20kHz) operation.
The device sustains 200A non-repetitive surge current (8.3ms half-sine) and exhibits dv/dt capability of 10,000 V/μs. Thermal performance is defined by RθJC = 1.5°C/W, requiring mechanical mounting with ≤0.56 N·m torque to maintain thermal integrity under continuous 30A conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for input voltage in DC-DC or adapter designs. |
| IF | 30 A - Continuous average forward current per diode; defines steady-state power handling capacity at rated case temperature. |
| IFSM | 200 A - Peak non-repetitive surge current; supports inrush tolerance during cold-start or fault conditions. |
| VF @ 15A, 25°C | 0.84 V - Forward voltage drop per diode; directly determines conduction loss (P = IF × VF) in efficiency-critical stages. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; enables thermal design of heatsink interface for 30A operation at TJ ≤ 150°C. |
| IR @ 100V, 125°C | 7.5 mA - Reverse leakage per diode; impacts standby power and thermal runaway risk in high-temp environments. |
Pinout & Package
Package: TO-220AB, 3-terminal molded plastic case with matte tin-plated leads, UL 94V-0 rated compound, polarity marked on body, weight ≈1.90g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode 1 | Input terminal for first Schottky junction; connects to AC or switched node in full-wave or center-tap topology. |
| Pin 2 (Center) | Cathode (Common) | Shared cathode output for both diodes; serves as DC+ output node in dual-anode configurations. |
| Pin 3 (Right) | Anode 2 | Input terminal for second Schottky junction; enables symmetrical full-wave rectification with shared cathode return. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.84 V max at 15A/25°C - reduces conduction loss by ~30% vs. comparable 100V Si rectifiers, improving system efficiency. |
| Dual-die common-cathode configuration | Two independent Schottky junctions sharing one cathode terminal - eliminates need for external parallel or series diode wiring in full-wave designs. |
| Guard ring overvoltage protection | Integrated edge termination structure - enhances ruggedness against transient voltage spikes without external snubbers. |
| High surge current rating | 200A IFSM (8.3ms) - withstands repeated inrush events in offline SMPS and motor drive auxiliary supplies. |
Applications
| Server Power Supply | Industrial DC-DC Converter |

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-30CPH100 | Same TO-220AB package, 30A/100V, VF = 0.82V @ 15A/25°C, RθJC = 1.4°C/W | Slightly lower VF and thermal resistance; tighter IR spec (5mA @ 125°C) | Preferred where margin in thermal headroom or leakage sensitivity is critical. |
| ON Semiconductor MBR30100CT | Identical electrical specs and TO-220AB package; RoHS-compliant but not halogen-free per IEC 61249-2-21 | No functional difference in circuit operation; differs only in material compliance documentation | Select when halogen-free certification is not required and cost or lead time favors ON Semi sourcing. |
Compared with MBR30100CT-Y, VS-30CPH100 offers marginally better thermal and conduction performance, while MBR30100CT provides identical functionality without halogen-free compliance - choice depends on thermal budget, leakage tolerance, and material declaration requirements.

FAQ
What is the maximum junction temperature rating for MBR30100CT-Y?
The MBR30100CT-Y has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient industrial environments when paired with appropriate heatsinking and airflow. Derating curves confirm usable current capacity down to 0A at 150°C case temperature. The MBR30100CT-Y must not exceed this limit to ensure reliability and avoid parametric shift.
Does MBR30100CT-Y have a common-cathode or common-anode configuration?
The MBR30100CT-Y uses a common-cathode (CT) configuration: Pin 2 is the shared cathode terminal, while Pins 1 and 3 serve as independent anodes. This layout supports full-wave rectification from center-tapped transformers or dual-switch topologies. The marking "CT" in MBR30100CT-Y explicitly denotes this common-cathode arrangement, confirmed in the ordering information and package diagram.
What is the forward voltage specification for MBR30100CT-Y at full rated current?
At 30A and 25°C junction temperature, the MBR30100CT-Y has a maximum forward voltage (VF) of 0.94V per diode, as specified in the Electrical Specifications table. At 125°C, VF rises to 0.82V - demonstrating positive temperature coefficient behavior typical of Schottky devices. These values are measured under pulsed conditions (PW = 0.3ms) and define worst-case conduction loss for thermal design.
Is MBR30100CT-Y halogen-free and RoHS compliant?
Yes, the MBR30100CT-Y is both RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section. The molding compound contains no brominated or chlorinated flame retardants, and all terminals meet J-STD-002 solderability standards. Compliance documentation is available upon request for MBR30100CT-Y for automotive or medical-grade qualification programs.
What is the thermal resistance from junction to case (RθJC) for MBR30100CT-Y?
The junction-to-case thermal resistance (RθJC) for MBR30100CT-Y is 1.5°C/W, as specified in the THERMAL PERFORMANCE table. This value applies to both MBR30100CT-Y and MBR30150CT-Y variants and is measured under standardized mounting conditions. It enables accurate calculation of junction temperature rise above case temperature (ΔTJ = RθJC × PD), critical for validating thermal design margins in continuous 30A operation.
