Product details
Overview
MBRS20100CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 20A average forward current, 100V repetitive peak reverse voltage, and 150A surge current, with 0.95V max forward voltage at 20A/25°C, used in high-efficiency DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the MBRS20100CT datasheet, MBRS20100CT pinout, MBRS20100CT application, or MBRS20100CT equivalent, key selection criteria include VRRM = 100 V, IF = 20 A, thermal resistance RθJC = 2.0 °C/W, low VF at high temperature, and TO-263AB surface-mount compatibility with automated assembly.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent die in a single D2PAK thermally optimized package, enabling synchronous or interleaved rectification topologies. Its 100 V VRRM supports 48 V and 54 V bus systems, while the 2.0 °C/W junction-to-case thermal resistance allows direct heatsinking to PCB copper or external metal.
The device exhibits 5 µA max reverse leakage per diode at 100 V and 125 °C, and maintains 0.85 V typical forward voltage at 10 A/125 °C - critical for maintaining efficiency in thermally constrained industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports 48 V input SMPS with 2× safety margin against transients |
| IF | 20 A continuous - enables single-device solution for 100–150 W output stages |
| IFSM | 150 A (8.3 ms) - withstands inrush and load-dump surges without failure |
| VF @ 20A/25°C | ≤ 0.95 V - reduces conduction loss vs. silicon diodes by ~40% at full load |
| RθJC | 2.0 °C/W - permits >15 W dissipation with 30 °C case rise, simplifying thermal design |
| IR @ 100 V/125°C | ≤ 5 mA - ensures low standby loss in high-temp environments like enclosed adapters |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal, common-cathode configuration with exposed thermal pad (pin 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode A) | First diode anode | Connects to transformer secondary or switching node for first rectifier path |
| 2 (Anode B) | Second diode anode | Enables dual-output or center-tapped rectification without extra package |
| 3 (Cathode) | Common cathode / thermal pad | Electrically and thermally ties both diodes; must be soldered to large copper pour for heat dissipation |

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-20CPH06-M3 | Same TO-263AB package, 60 V VRRM, lower VF (0.57 V @ 20 A/25°C), higher IFSM (200 A) | Not suitable for 100 V bus designs; better for 24–48 V systems requiring ultra-low VF | Select only when VRRM margin can be reduced and lower conduction loss is prioritized over voltage rating |
| ON Semiconductor MBR20100CT | Identical ratings (20 A, 100 V), same D2PAK package, but RθJC = 2.2 °C/W and VF = 0.98 V max @ 20 A/25°C | Functionally interchangeable in most layouts; slightly higher thermal resistance may require larger copper area | Valid drop-in alternative where Taiwan Semiconductor supply is constrained; verify layout thermal performance |
Compared with VS-20CPH06-M3 and MBR20100CT, the MBRS20100CT offers optimal balance of 100 V rating, 2.0 °C/W thermal resistance, and proven reliability in high-temp industrial deployments - making it preferred for 48 V server and telecom power where voltage margin and thermal headroom are critical.

FAQ
What is the maximum junction temperature rating for MBRS20100CT?
The MBRS20100CT has a maximum junction temperature (TJ) of +150 °C, with operational range from –55 °C to +150 °C. This rating enables reliable operation in enclosed industrial enclosures and automotive under-hood environments when mounted on adequate copper area. The device's thermal performance is validated per JESD51-14 standards, and its RθJC = 2.0 °C/W allows precise junction temperature estimation using measured case temperature.
Does MBRS20100CT support lead-free reflow soldering?
Yes, MBRS20100CT supports standard lead-free reflow profiles (J-STD-020 Level 1), with matte tin-plated terminals qualified per J-STD-002 for solderability. Its moisture sensitivity level is rated at MSL-1, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking prior to assembly - eliminating process overhead in high-volume SMT lines.
How does the guard ring feature improve reliability of MBRS20100CT?
The guard ring in MBRS20100CT mitigates electric field crowding at the silicon periphery, preventing premature avalanche breakdown under repetitive 100 V reverse bias. This structural enhancement extends lifetime in applications with voltage transients, such as 48 V telecom systems experiencing load dumps or inductive kickback, and is verified through 1,000-hour HTGB testing at 125 °C and rated VRRM.
Can MBRS20100CT be used in parallel configurations?
MBRS20100CT is not recommended for direct parallel operation due to inherent VF mismatch between dies and lack of integrated current-sharing features. For higher current requirements, use separate MBRS20100CT devices in independent branches with matched trace lengths and thermal coupling, or select a higher-rated part like MBRS30100CT. Parallel use without balancing resistors risks thermal runaway above 85 °C ambient.
What is the reverse leakage current of MBRS20100CT at elevated temperature?
At 100 V reverse voltage and 125 °C junction temperature, MBRS20100CT specifies a maximum reverse leakage current (IR) of 5 mA per diode. This value is measured under pulsed conditions (30 ms pulse width) and reflects worst-case behavior in high-temp industrial adapters or enclosed power supplies - enabling accurate standby loss calculation and thermal modeling.
