Product details
Overview
MBRF1690H from Taiwan Semiconductor is a 16A, 90V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.85V max forward voltage at 16A/25°C, 150A surge current capability, and guard ring–enhanced over-voltage protection for automotive-grade power conversion.
For engineers reviewing the MBRF1690H datasheet, MBRF1690H pinout, MBRF1690H application, or MBRF1690H equivalent, key selection criteria include its 90V repetitive peak reverse voltage, 3°C/W junction-to-case thermal resistance, low leakage (300µA @ 90V/25°C), and AEC-Q101 qualification for under-hood SMPS and DC-DC converter designs.
Technical Context
This single-die Schottky rectifier operates with a maximum junction temperature of 150°C and supports continuous forward current up to 16A at case temperatures ≤75°C. Its 10,000 V/µs critical dv/dt rating enables stable switching in high-frequency converters.
The device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance. Its UL 94V-0 molding compound and polarity marking ensure reliable mounting and orientation in production environments.

FAQ
Is MBRF1690H pin-compatible with standard TO-220AC rectifiers?
No, MBRF1690H uses the ITO-220AC package, which has an electrically isolated tab and different lead spacing than standard TO-220AC. The ITO-220AC tab is internally connected to the cathode and must be mounted to a heatsink with insulating hardware if voltage isolation is required. Always verify land pattern against TSC's official ITO-220AC outline drawing before PCB layout.
What is the maximum allowable case temperature for continuous operation of MBRF1690H?
The MBRF1690H supports continuous operation up to 75°C case temperature at full 16A forward current, per its derating curve. Above 75°C, current must be linearly reduced to maintain junction temperature ≤150°C. At 100°C case temperature, maximum sustainable IF drops to approximately 10.5A.
Does MBRF1690H require a heatsink in typical 16A applications?
Yes, MBRF1690H requires a heatsink in all 16A continuous applications. With RθJC = 3°C/W and typical power dissipation of ~13.6W (16A × 0.85V), even a modest 10°C/W heatsink results in ~40°C junction-to-ambient rise-exceeding safe limits without thermal management. A minimum 5°C/W heatsink is recommended for ambient ≤50°C.
How does the guard ring in MBRF1690H improve reliability?
The guard ring in MBRF1690H mitigates edge-related avalanche breakdown under high dv/dt or transient overvoltage conditions. It redistributes electric field concentration at the silicon periphery, enabling stable 90V reverse operation with >10,000 V/µs critical rate-of-rise tolerance-critical for automotive load-dump immunity and industrial switching noise resilience.
Can MBRF1690H replace MBRF16100 in a 100V design?
No, MBRF1690H is rated for 90V VRRM, while MBRF16100 is rated for 100V. Substituting MBRF1690H in a 100V design risks reverse breakdown during transients or line surges. The 10V margin difference is insufficient for safety-critical or high-reliability applications. Use MBRF16100 or MBRF16150 for ≥100V systems.
