Product details
Overview
MBR3100VRTR-E1 from Diodes Incorporated is a high-voltage Schottky rectifier in DO-214AC package, rated for 100 V peak reverse voltage, 3 A average forward current, and 0.85 V max forward voltage at +25°C. It delivers low switching losses and low noise in high-frequency switch-mode power supplies and DC-DC converters.
For engineers reviewing the MBR3100VRTR-E1 datasheet, MBR3100VRTR-E1 pinout, MBR3100VRTR-E1 application, or MBR3100VRTR-E1 equivalent, key selection criteria include its 80 A non-repetitive surge rating, 150°C junction temperature capability, guard-ring stress protection, and RoHS-compliant "Green" packaging with matte tin annealed terminals.
Technical Context
This Schottky rectifier uses a planar epitaxial construction with integrated guard-ring structure to enhance ruggedness against transient overvoltage and thermal stress. Its low VF and fast recovery enable high-efficiency rectification in medium-voltage, high-frequency topologies such as flyback and forward converters.
The device operates across –65°C to +150°C junction temperature range, with thermal resistance of 20°C/W (junction-to-lead) and 70°C/W (junction-to-ambient) under specified pad layout. ESD ratings are 400 V (machine model) and 8000 V (HBM), supporting robust handling in automated assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands repetitive reverse voltage up to this level without breakdown in SMPS output stages. |
| IF(AV) | 3 A - Sustains continuous forward conduction at case temperature ≤+141°C, enabling compact heatsink design. |
| VF (MAX) | 0.85 V @ 3A, +25°C - Minimizes conduction loss and self-heating in high-current, high-duty-cycle operation. |
| IR (MAX) | 0.5 mA @ 100 V, +25°C - Limits leakage-induced inefficiency and standby power loss in offline adapters. |
| IFS M | 80 A - Handles short-duration line surges without failure, supporting reliable startup and fault transients. |
| TJ Range | –65°C to +150°C - Enables deployment in industrial and automotive under-hood environments with wide ambient swings. |
| RθJL | 20°C/W - Supports direct thermal coupling to PCB copper pour or heatsink for stable thermal management. |

Applications
| Server Power Supply Rectification | Industrial DC-DC Converter Output |
|---|---|
Use Scenario: High-density 12 V/48 V output stage in ATX or EPS server PSUs operating at 100–500 kHz. IC Role / Device Role / Timing Role: Primary output rectifier replacing fast recovery diodes to reduce conduction loss and EMI. Use Value: 0.85 V VF cuts rectifier power loss by ~35% vs. Si FRD, lowering thermal load on heatsinks and improving system efficiency. | Use Scenario: Isolated 24 V output in programmable logic controller (PLC) power modules with wide ambient range. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier alternative where gate drive complexity is avoided. Use Value: 150°C TJ rating ensures uninterrupted operation at 70°C ambient + 40°C rise, eliminating thermal shutdown risk. |
| Medical Equipment AC-DC Adapter | Automotive Infotainment Power Rail |
Use Scenario: Compact wall-mounted adapter for portable diagnostic devices requiring low-noise, low-leakage output. IC Role / Device Role / Timing Role: Low-noise rectifier minimizing conducted EMI into sensitive analog front-ends. Use Value: 0.5 mA IR at +25°C reduces standby current and improves no-load regulation versus standard Schottkys. | Use Scenario: 5 V/3.3 V auxiliary rail in head unit power tree exposed to under-dash temperature cycling. IC Role / Device Role / Timing Role: Input-stage rectifier for buck-derived bias supply feeding CAN/LIN transceivers. Use Value: Guard-ring structure withstands load-dump transients up to ISO 7637-2 Pulse 5a, enhancing system-level robustness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS310 (ON Semiconductor) | Same 100 V / 3 A rating, but VF = 0.87 V @ 3A, +25°C; no guard ring; RθJA = 75°C/W. | Lacks guard-ring protection; less robust in surge-prone industrial environments. | Acceptable where cost sensitivity outweighs transient immunity requirements. |
| SB3100 (Vishay) | Identical electrical specs; same DO-214AC package; VF = 0.85 V @ 3A, +25°C; includes guard ring. | Functionally identical; qualified per AEC-Q101 for automotive use. | Preferred for automotive-grade designs requiring extended qualification evidence. |
Compared with SS310, MBR3100VRTR-E1 offers superior surge resilience and thermal performance; versus SB3100, it provides equivalent functionality at lower cost but without AEC-Q101 certification-making it ideal for industrial and commercial power supplies where qualification overhead is unnecessary.

FAQ
What is the maximum junction temperature for MBR3100VRTR-E1?
The absolute maximum operating junction temperature is +150°C, verified per JEDEC JESD22-A108. This allows full 3 A current delivery at case temperatures up to +141°C when mounted per recommended pad layout, making it suitable for thermally dense PCBs without active cooling.
Is MBR3100VRTR-E1 compatible with lead-free reflow soldering?
Yes-its matte tin annealed terminals meet IPC/JEDEC J-STD-020 moisture sensitivity Level 1 and are fully compatible with standard lead-free reflow profiles (peak 260°C). The DO-214AC package has been qualified for >1000 thermal cycles without delamination or solder joint fracture.
Does MBR3100VRTR-E1 have a built-in guard ring?
Yes-the device integrates a silicon guard ring around the active junction, confirmed in the "Features" section of DS36956 Rev. 4-2. This structure prevents premature edge breakdown during voltage transients and improves long-term reliability in unregulated or noisy input conditions.
How does the 80 A IFSM rating translate to real-world surge handling?
The 80 A non-repetitive peak surge current is validated per half-wave, single-phase, 60 Hz test condition. In practice, this enables safe handling of 10 ms line surges up to 60 A and brief start-up inrush events in offline SMPS without degradation-provided thermal mass and layout limit junction temperature rise below 150°C.
