Product details
Overview
MBRS1050 MNG from Taiwan Semiconductor is a 10A, 50V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, optimized for high-efficiency DC/DC conversion with 0.80 V forward voltage at 10A and 25°C, 120A surge capability, and 175°C maximum junction temperature. It serves as the primary output rectifier in compact switching power supplies.
For engineers reviewing the MBRS1050 MNG datasheet, MBRS1050 MNG pinout, MBRS1050 MNG application, or MBRS1050 MNG equivalent, key selection criteria include its 50V reverse voltage rating, low VF at high current, thermal resistance (RθJC = 2°C/W), RoHS/halogen-free compliance, and suitability for automated SMT assembly in space-constrained industrial adapters.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its low forward voltage minimizes conduction loss in high-frequency SMPS topologies operating up to 1 MHz.
The device achieves 120A non-repetitive surge current handling (8.3 ms half-sine) and maintains stable reverse leakage (<10 mA at 125°C) while operating across –55°C to +175°C junction range - enabling reliable performance in thermally demanding embedded power rails.
Key Specifications

| IF | 10 A continuous - Rated average forward current; supports 12–24 V output rails delivering up to 240 W with proper heatsinking |
| VF @ 10A, 25°C | 0.80 V - Low conduction loss reduces power dissipation by ~25% vs. comparable 60V Schottkys |

| Moisture Sensitivity | Level 1 (J-STD-020) - No bake required before reflow; compatible with standard SMT lines |
Pinout & Package
Package: TO-263AB (D2PAK) - Surface-mount power package with exposed cathode tab for thermal and electrical connection; 3-terminal configuration (Anode, Cathode, Cathode Tab).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to switch node (e.g., MOSFET drain) in synchronous rectification or freewheeling path |
| Cathode (Lead 2) | Output current exit point | Routes rectified current to output capacitor and load; electrically tied to cathode tab |
| Cathode Tab (Exposed Pad) | Primary cathode terminal & thermal path | Soldered directly to large PCB copper area for low-inductance return and thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents premature edge breakdown under voltage transients, improving reliability in noisy DC/DC outputs |
| Low VF at high IF | 0.95 V @ 10A, 125°C - Maintains efficiency during thermal stress, reducing thermal runaway risk |
| High IFSM/IF ratio (12:1) | Enables robustness against inrush currents in hot-plug or capacitive-load applications |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS - meets environmental requirements for global industrial shipments |
| Matte tin plating | Ensures consistent wetting and joint integrity per J-STD-002 - eliminates voiding in high-volume reflow |

FAQ
What is the maximum junction temperature rating for MBRS1050 MNG?
The MBRS1050 MNG has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version K2103). This allows sustained operation in high-ambient environments such as enclosed industrial power supplies or automotive under-hood auxiliary rails when properly heatsinked via its exposed cathode tab.
Does MBRS1050 MNG support lead-free reflow soldering?
Yes, MBRS1050 MNG features matte tin-plated leads qualified per J-STD-002 for solderability and is rated for lead-free reflow profiles (peak temperature up to 260°C). Its moisture sensitivity level is J-STD-020 Level 1, meaning no pre-bake is required prior to standard SMT reflow processing - simplifying manufacturing for high-volume Aetrix customers.
What is the forward voltage of MBRS1050 MNG at 10A and 125°C?
The forward voltage (VF) of MBRS1050 MNG is specified as 0.70 V maximum at 10A and 125°C, per the Electrical Specifications table in the Taiwan Semiconductor datasheet (Version K2103, page 2). This value reflects real-world thermal performance under sustained load, critical for calculating conduction losses in thermally constrained designs.
Is MBRS1050 MNG halogen-free and RoHS compliant?
Yes, MBRS1050 MNG is both halogen-free per IEC 61249-2-21 and RoHS compliant, as explicitly stated in the Features section of the official Taiwan Semiconductor datasheet (Version K2103, page 1). These certifications are verified through material declarations and are maintained across all production lots shipped by Aetrix Electronics.
What package type does MBRS1050 MNG use, and how many terminals does it have?
MBRS1050 MNG uses the TO-263AB (D2PAK) surface-mount package with three terminals: Anode (lead 1), Cathode (lead 2), and Cathode Tab (exposed metal pad). The cathode tab serves as both the primary cathode connection and main thermal path - requiring direct soldering to a large PCB copper area for optimal performance.
