Product details
Overview
MBRS1690H from Taiwan Semiconductor is a 16A, 90V Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for low forward voltage drop (0.85 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 MBRS1690H datasheet, MBRS1690H pinout, MBRS1690H application, or MBRS1690H equivalent, key selection criteria include its 90 V VRRM rating, 0.85 V VF at full rated current, 7.5 mA IR at 125°C, 1.5 °C/W RθJC thermal resistance, and AEC-Q101 qualification for automotive environments.
Technical Context
The MBRS1690H uses a single-die Schottky junction structure with guard ring overvoltage protection, enabling stable operation up to 150°C junction temperature. Its low VF and high IFSM support high-efficiency, high-current switching in compact power stages.
Designed for surface-mount automated assembly, it features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Moisture sensitivity level is rated J-STD-020 Level 1 - unlimited floor life at ≤30°C/60% RH.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum junction temperature rating for MBRS1690H?
The MBRS1690H has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows sustained operation in underhood automotive environments and high-power-density industrial converters. Derating curves confirm usable current down to 0 A at 150°C case temperature. The MBRS1690H must be mounted with adequate copper area to maintain TJ ≤ 150°C under full 16 A load.
Is MBRS1690H pin-compatible with other parts in the MBRS16xxH series?
Yes - all MBRS16xxH variants (e.g., MBRS1635H, MBRS1660H, MBRS16150H) share identical TO-263AB (D2PAK) package dimensions, pinout, and terminal configuration. The MBRS1690H uses the same Anode–NC–Cathode lead assignment and mechanical outline, enabling voltage-scaling design reuse across the family without layout changes.
Does MBRS1690H require a heatsink for 16 A continuous operation?
Not necessarily - the MBRS1690H achieves 16 A continuous current with proper PCB heatsinking: ≥200 mm² of 2-oz copper connected to the cathode tab, plus optional external metal slug. Its 1.5 °C/W RθJC enables <30°C temperature rise above heatsink at 10 W dissipation. Forced air or dedicated heatsink is only needed if ambient exceeds 85°C or power loss exceeds 12 W.
What is the reverse leakage current of MBRS1690H at elevated temperature?
At 90 V reverse bias and 125°C junction temperature, the MBRS1690H exhibits a maximum reverse leakage current (IR) of 7.5 mA, per electrical specifications table. This value is confirmed by pulse testing (PW = 30 ms) and is significantly lower than lower-voltage variants (e.g., MBRS1635H shows 15 mA at same condition), reflecting optimized junction design for higher VRRM.
Can MBRS1690H be used in reverse-battery protection circuits?
Yes - the MBRS1690H is explicitly listed in its applications for reverse battery protection. With 90 V VRRM and low 0.85 V forward voltage, it blocks reverse polarity up to ±90 V while minimizing voltage drop and power loss in forward conduction. Its AEC-Q101 qualification and guard ring structure further ensure robustness against load dump transients and ESD events common in automotive battery lines.
