Product details
Overview
MBR3100VRTR-G1 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, serving as output rectification diode in AC/DC and DC/DC converters.
For engineers reviewing the MBR3100VRTR-G1 datasheet, MBR3100VRTR-G1 pinout, MBR3100VRTR-G1 application, or MBR3100VRTR-G1 equivalent, key selection criteria include its 80 A non-repetitive surge rating, 150°C junction temperature capability, guard-ring stress protection, RoHS-compliant green packaging, and thermal resistance of 20°C/W (junction-to-lead).
Technical Context
This Schottky rectifier uses a metal–semiconductor junction to achieve fast recovery (no minority carrier storage) and zero reverse recovery charge, enabling efficient operation above 100 kHz. Its 10000 V/µs voltage rate of change supports rapid voltage transients in high-speed switching topologies.
The device features a guard-ring structure that enhances ruggedness against voltage overstress and transient-induced edge breakdown. Thermal design is supported by low RθJL (20°C/W) when mounted on a heat sink with recommended pad layout, allowing sustained 3 A conduction at TC = +141°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking range in 48 V–72 V bus applications. |
| IF(AV) | 3 A - Average forward current at TC = +141°C; enables continuous 3 A output rectification with proper heatsinking. |
| VF (MAX) | 0.85 V @ 3 A, +25°C - Low forward drop reduces conduction loss and improves efficiency in high-current SMPS outputs. |
| IR (MAX) | 0.5 mA @ 100 V, +25°C - Low leakage preserves efficiency in standby and light-load conditions. |
| IFS M | 80 A - Non-repetitive surge current rating; withstands inrush and fault currents in power supply startup or overload events. |
| TJ Range | −65°C to +150°C - Wide operating junction temperature supports industrial and automotive under-hood environments. |
| RθJL | 20°C/W - Junction-to-lead thermal resistance; enables direct thermal path to PCB copper or heatsink for reliable 3 A operation. |
Pinout & Package
Package: DO-214AC (SMA), molded plastic case with matte tin–annealed copper leadframe, UL 94V-0 rated, moisture sensitivity level 1, weight ≈1.9 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to input side (e.g., transformer secondary or switching node); polarity-sensitive for correct rectification flow. |
| Cathode | Forward current exit / reverse voltage reference | Marked with cathode band; ties to output rail or filter capacitor; serves as common reference for reverse blocking. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.85 V max at 3 A, +25°C - Reduces power dissipation by ~25% vs. comparable 1.1 V Si diodes, lowering thermal load. |
| Guard-ring protected junction | Integrated edge termination - Improves voltage ruggedness and reliability under repetitive dv/dt stress up to 10,000 V/µs. |
| High surge current capacity | 80 A IFSM - Supports robust handling of 60 Hz half-wave surges and transient overloads without degradation. |
| Green, RoHS-compliant construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); matte tin finish - Meets environmental compliance and solderability standards (MIL-STD-202). |

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 |
|---|---|---|---|
| SS310H from Micro Commercial Components | Same DO-214AC package, 100 V VRRM, 3 A IF(AV), but VF = 0.87 V @ 3 A - slightly higher conduction loss. | Identical use in SMPS output rectification; lower surge rating (60 A vs. 80 A) limits fault tolerance. | Acceptable where surge margin is relaxed and cost sensitivity outweighs thermal performance. |
| SB3100 from Vishay | DO-214AC, 100 V, 3 A, VF = 0.82 V @ 3 A - marginally lower forward drop; IR = 1.0 mA @ 100 V - double the leakage. | Better efficiency at light loads but higher leakage may impact standby power in energy-sensitive designs. | Preferred for ultra-low-loss designs where leakage is not constrained by regulatory limits (e.g., ENERGY STAR Tier 2). |
Compared with SS310H and SB3100, MBR3100VRTR-G1 offers the best balance of surge robustness (80 A), low leakage (0.5 mA), and proven guard-ring reliability-making it optimal for industrial-grade power supplies requiring long-term stability under thermal and electrical stress.

FAQ
Is MBR3100VRTR-G1 suitable for automotive applications?
No-MBR3100VRTR-G1 is not AEC-Q101 qualified and is explicitly marked "NOT RECOMMENDED FOR NEW DESIGN" for automotive use. Diodes Incorporated offers AEC-Q101-qualified alternatives (e.g., MBR3100Q) with PPAP support and IATF 16949 manufacturing; consult your local representative for qualified variants.
What is the maximum allowable case temperature for continuous 3 A operation?
The datasheet specifies IF(AV) = 3 A at TC = +141°C. To sustain this, thermal design must ensure junction temperature remains ≤ +150°C. With RθJL = 20°C/W, the maximum allowed power dissipation is 3 A × 0.85 V = 2.55 W, requiring a lead-to-ambient thermal path ≤ 58.8°C/W to stay within limits.
Does MBR3100VRTR-G1 have reverse recovery time (trr) specification?
No-Schottky rectifiers like MBR3100VRTR-G1 have no minority carrier storage, so trr is effectively zero. This eliminates reverse recovery loss and associated EMI, confirmed by the absence of trr in all electrical characteristics tables and the stated "fast recovery" behavior in the product summary.
Can MBR3100VRTR-G1 be used in place of a standard PN-junction rectifier like 1N5408?
Only in limited cases: MBR3100VRTR-G1 has lower VF (0.85 V vs. ~1.1 V) and zero trr, improving efficiency and EMI-but its 100 V VRRM is lower than 1N5408's 1000 V. Substitution is valid only if circuit reverse voltage stays ≤100 V; otherwise, catastrophic failure will occur due to insufficient blocking capability.
