Product details
Overview
MBRS1650 from Taiwan Semiconductor is a 16A, 50V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, featuring 0.75V forward voltage at 16A/25°C, 150A surge current capability, and junction temperature rating up to +150°C. It serves as a high-efficiency output rectifier in DC-DC converters and switching power supplies where low conduction loss and fast recovery are critical.
For engineers reviewing the MBRS1650 datasheet, MBRS1650 pinout, MBRS1650 application, or MBRS1650 equivalent, key selection criteria include its 50V VRRM rating, thermal resistance of 1.5°C/W, moisture sensitivity level 1 compliance, RoHS/halogen-free status, and suitability for automated SMT assembly in high-current power stages.
Technical Context
The MBRS1650 uses a single-die Schottky structure optimized for low VF and high IFSM, with guard ring protection enabling robust overvoltage tolerance. Its TO-263AB package provides low thermal resistance (RθJC = 1.5°C/W) and supports high-current PCB trace routing via the exposed cathode tab.
Electrical behavior is characterized by temperature-dependent forward voltage (0.65V max at 16A/125°C) and reverse leakage (10mA max at 125°C), with stable performance across -55°C to +150°C junction range and 100µA max IR at 25°C under rated VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or synchronous rectifier topologies |
| IF | 16 A - Continuous forward current rating; determines minimum trace width and heatsinking in 12–48V output stages |
| IFSM | 150 A - Non-repetitive surge current; enables survival during power-up inrush or short-circuit events |
| VF @ 16A, 25°C | 0.75 V - Forward voltage drop; directly impacts conduction loss (P = IF × VF) and thermal design |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; allows accurate calculation of case temperature rise under load |
| TJ max | +150 °C - Maximum junction temperature; sets upper boundary for thermal management margin in sealed enclosures |
| IR @ 50V, 125°C | 10 mA - Reverse leakage current; affects standby power loss and reliability in high-temp environments |

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-MBR1650CT | TO-220AC package, dual common-cathode configuration, VF = 0.72V @ 16A/25°C | Requires through-hole assembly and separate cathode routing; not surface-mount compatible | Select when legacy through-hole layout exists and thermal mass of TO-220 is preferred |
| ON Semiconductor MBR1650CT | D2PAK-3L package, same pinout, VF = 0.74V @ 16A/25°C, TJ max = +175°C | Higher junction temperature rating enables extended operation in ambient >85°C environments | Select when extended thermal margin is required and JEDEC-compliant D2PAK footprint is confirmed |
Compared with VS-MBR1650CT and MBR1650CT, the MBRS1650 offers identical D2PAK footprint and MSL-1 handling, but with tighter VF consistency at 125°C (0.65V max) and guaranteed halogen-free construction per IEC 61249-2-21.

FAQ
What is the maximum junction temperature rating for the MBRS1650?
The MBRS1650 has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This rating allows continuous operation in high-ambient environments when thermal design accounts for RθJC = 1.5°C/W and PCB copper area. Derating curves confirm usable current down to 10A at 125°C case temperature.
Does the MBRS1650 have a guarded die structure?
Yes, the MBRS1650 incorporates a guard ring structure explicitly stated in its features list to provide overvoltage protection. This design enhances avalanche ruggedness and improves reliability during transient voltage events such as load dumps or inductive switching spikes in DC-DC converter outputs.
Is the MBRS1650 compliant with RoHS and halogen-free standards?
Yes, the MBRS1650 is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the official Taiwan Semiconductor documentation. The molding compound and plating meet UL 94V-0 flammability and JESD 201 Class 2 whisker resistance requirements.
What is the forward voltage specification of the MBRS1650 at elevated temperature?
The MBRS1650 exhibits a forward voltage of 0.65V maximum at 16A and 125°C junction temperature, per electrical specifications table. This value is critical for thermal modeling, as it reflects reduced VF drift compared to lower-voltage variants in the same family, supporting stable performance in hot-running power stages.
What packaging and moisture sensitivity level does the MBRS1650 use?
The MBRS1650 is supplied in TO-263AB (D2PAK) package on tape-and-reel (800 units per reel) and carries moisture sensitivity level (MSL) 1 per J-STD-020. This eliminates bake requirements prior to reflow, simplifying SMT line integration and reducing risk of popcorning during assembly.
