Product details
Overview
MBRS1650H from Taiwan Semiconductor is a 16 A, 50 V Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for low forward voltage drop (0.75 V at 16 A, 25°C), high surge capability (150 A IFSM), and automotive-grade reliability (AEC-Q101 qualified). It serves as a freewheeling or reverse-battery protection diode in DC/DC converters and car lighting systems.
For engineers reviewing the MBRS1650H datasheet, MBRS1650H pinout, MBRS1650H application, or MBRS1650H equivalent, key selection criteria include its 50 V VRRM rating, 1.5 °C/W RθJC thermal resistance, TJ = –55 to +150°C operating range, and TO-263AB surface-mount compatibility with automated placement.
Technical Context
The MBRS1650H uses a single-die Schottky junction structure with guard ring overvoltage protection, enabling fast switching and low conduction loss. Its 0.75 V forward voltage at 16 A and 25°C directly reduces power dissipation in high-current, high-frequency rectification paths.
Thermally, it features a low junction-to-case resistance of 1.5 °C/W and supports continuous operation up to 150°C junction temperature, making it suitable for compact, thermally constrained automotive and industrial power stages where thermal management is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage; defines safe blocking capability in reverse-biased applications like reverse battery protection. |
| IF | 16 A - Continuous forward current rating; supports high-current DC/DC output rectification without derating at TA ≤ 75°C. |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in automotive power rails. |
| VF @ 16 A, 25°C | 0.75 V - Low forward voltage drop; minimizes conduction loss and improves system efficiency in low-voltage, high-current paths. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; enables effective heat transfer to heatsink or PCB copper when mounted on large thermal pads. |
| TJ Range | –55 to +150°C - Extended junction temperature range; certified for under-hood automotive environments per AEC-Q101. |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal case with exposed cathode tab for thermal and electrical connection. Matte tin-plated leads, moisture sensitivity level 1 (J-STD-020), RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current input | Connects to positive side of source; carries full load current into device during conduction. |
| Cathode (Tab / Lead 2) | Forward current output / Heat sink interface | Primary current return path and main thermal conduction surface; must be soldered to large copper area for thermal performance. |
| NC / Case (Lead 3) | Not connected / Mechanical anchor | Electrically isolated mounting tab; provides mechanical stability but no electrical function-no internal connection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity, and mechanical shock-enables deployment in engine control and lighting modules. |
| Guard ring structure | Enhances edge termination robustness against transient overvoltage events, improving reliability in noisy automotive power nets. |
| Low VF at high IF | 0.75 V at 16 A and 25°C reduces power loss by ~12% vs. comparable 60 V Schottkys, directly lowering thermal design margin requirements. |
| TO-263AB package | Enables automated pick-and-place assembly and high-current PCB routing via large cathode tab; compatible with standard D2PAK reflow profiles. |

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 = 0.74 V @ 16 A, 25°C; VRRM = 50 V; no AEC-Q101 certification. | Requires through-hole mounting and separate cathode routing; not qualified for automotive under-hood use. | Select if board space permits through-hole layout and AEC-Q101 is not required. |
| ON Semiconductor MBR1650CT | TO-220AB package, single die, VF = 0.76 V @ 16 A, 25°C; VRRM = 50 V; AEC-Q101 qualified but rated only to TJ = 125°C (vs. 150°C). | Limited thermal headroom in high-ambient environments; lower max junction temperature constrains power density. | Choose when legacy TO-220 footprint is fixed and peak ambient temperature remains below 75°C. |

FAQ
What is the maximum junction temperature rating for MBRS1650H?
The MBRS1650H has a maximum junction temperature (TJ) rating of +150°C, validated per AEC-Q101 stress testing. This allows sustained operation in under-hood automotive environments where ambient temperatures exceed 105°C. The device's 1.5 °C/W RθJC enables effective thermal coupling to PCB copper, ensuring MBRS1650H maintains safe junction temperatures even at full 16 A load in thermally demanding layouts.
Is MBRS1650H qualified for automotive applications?
Yes, MBRS1650H is AEC-Q101 qualified, confirming its suitability for automotive electronic systems. Qualification includes stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life. This makes MBRS1650H appropriate for use in car lighting, body control modules, and infotainment power supplies where reliability under harsh conditions is mandatory.
What is the forward voltage drop of MBRS1650H at rated current?
The MBRS1650H exhibits a typical forward voltage (VF) of 0.75 V at 16 A and 25°C, rising to 0.65 V at 16 A and 125°C. This low, temperature-stable VF minimizes conduction losses in high-current paths. At full load and elevated temperature, MBRS1650H delivers predictable performance without thermal runaway risk-critical for unregulated or high-duty-cycle applications.
Does MBRS1650H have a guard ring structure?
Yes, MBRS1650H incorporates a guard ring for overvoltage protection, as explicitly stated in its official datasheet features. This structure enhances edge termination robustness, improving resistance to transient voltage spikes and localized avalanche breakdown-particularly valuable in automotive systems exposed to load dump and jump-start events where MBRS1650H operates as a primary protection element.
What packaging and moisture sensitivity level does MBRS1650H use?
MBRS1650H is supplied in TO-263AB (D2PAK) package on 800-unit tape-and-reel, with moisture sensitivity level (MSL) 1 per J-STD-020-meaning it is not humidity-sensitive and requires no dry-pack or baking prior to reflow. Its matte tin-plated leads ensure reliable solderability, and the UL 94V-0 molding compound meets stringent flammability requirements for automotive and industrial end equipment.
