Product details
Overview
MBRS1690 MNG from Taiwan Semiconductor is a 16A, 90V Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for high-efficiency DC/DC conversion with low forward voltage (0.85V at 16A, 25°C) and high surge capability (150A IFSM). It serves as the primary output rectifier in compact switching power supplies.
For engineers reviewing the MBRS1690 MNG datasheet, MBRS1690 MNG pinout, MBRS1690 MNG application, or MBRS1690 MNG equivalent, key selection criteria include its 90V VRRM rating, 1.5°C/W junction-to-case thermal resistance, TJ = –55°C to +150°C operating range, and moisture sensitivity level 1 compliance for automated SMT assembly.
Technical Context
This single-die Schottky rectifier uses a guard-ringed silicon structure to enhance overvoltage ruggedness while maintaining low conduction loss. Its VF increases only marginally from 0.85V at 25°C to 0.82V at 125°C under 16A DC load, supporting stable thermal performance in high-density power stages.
With 300µA reverse leakage at 90V and 25°C - lower than 500µA in 35–60V variants - the MBRS1690 MNG balances higher blocking voltage against controlled IR drift, making it suitable for 48V-input SMPS where reverse recovery and leakage trade-offs are critical.

FAQ
What is the maximum junction temperature rating for MBRS1690 MNG?
The MBRS1690 MNG has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This allows sustained operation in high-ambient environments such as enclosed power supplies or under-hood automotive applications. Derating curves confirm usable current capacity down to 10A at 125°C case temperature. The MBRS1690 MNG must be mounted with adequate copper area to maintain TJ ≤ 150°C under full 16A load.
Does MBRS1690 MNG have a halogen-free construction?
Yes, the MBRS1690 MNG is halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet. Its molding compound contains no brominated or chlorinated flame retardants, and all terminations use matte tin plating compliant with RoHS Directive 2011/65/EU. This makes the MBRS1690 MNG suitable for green electronics manufacturing and export to regulated markets.
What is the reverse leakage current specification for MBRS1690 MNG at 90V and 125°C?
At rated VRRM = 90V and TJ = 125°C, the MBRS1690 MNG exhibits a maximum reverse leakage current (IR) of 7.5 mA, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This value is confirmed under pulse test conditions (PW = 30ms) and reflects real-world behavior in high-temperature operation. The MBRS1690 MNG maintains lower IR than lower-voltage variants (e.g., MBRS1660) due to optimized doping and guard ring design.
Is MBRS1690 MNG pin-compatible with other parts in the MBRS16xx family?
Yes, all MBRS16xx devices - including MBRS1690 MNG - share identical TO-263AB (D2PAK) mechanical dimensions, pinout, and thermal pad configuration. The anode, cathode, and exposed pad positions are standardized across the family. However, electrical parameters (VRRM, VF, IR) differ by voltage grade, so substitution requires verification of circuit voltage and thermal margins. The MBRS1690 MNG is mechanically interchangeable but not functionally drop-in with MBRS1635 or MBRS16150.
What is the surge current rating of MBRS1690 MNG and how is it tested?
The MBRS1690 MNG has a peak non-repetitive forward surge current (IFSM) rating of 150A, tested using an 8.3ms single half-sine wave superimposed on rated DC load, per JEDEC standards. This rating is validated at TA = 25°C and confirms robustness against inrush, short-circuit, and transient events. The MBRS1690 MNG sustains this surge without parametric shift or bond-wire failure, provided junction temperature remains within limits. Layout must ensure low-inductance paths to avoid voltage overshoot during surge.
