Product details
Overview
MBRF790H from Taiwan Semiconductor is a 7.5A, 90V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.92V forward voltage at 7.5A/25°C, 150A surge capability, and guard ring over-voltage protection-used in automotive-grade DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the MBRF790H datasheet, MBRF790H pinout, MBRF790H application, or MBRF790H equivalent, key selection criteria include its 90V VRRM, AEC-Q101 qualification, 7°C/W junction-to-case thermal resistance, and compatibility with high-efficiency, high-reliability power conversion designs requiring low conduction loss and robust surge handling.
Technical Context
This single-die Schottky rectifier operates with a maximum junction temperature of 150°C and supports repetitive reverse voltages up to 90V (VRRM). Its 150A non-repetitive surge current rating (8.3ms half-sine) and 10,000 V/µs dv/dt capability enable reliable operation in fast-switching topologies.
At 125°C junction temperature, forward voltage remains 0.82V at 7.5A, ensuring stable conduction under thermal stress. Reverse leakage is limited to 5mA at rated VR and 125°C, supporting low-power-loss standby modes in automotive power supplies.

FAQ
What is the peak repetitive reverse voltage rating for MBRF790H?
The MBRF790H has a peak repetitive reverse voltage (VRRM) rating of 90 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2105), and defines the maximum reverse-biased voltage the device can block continuously without breakdown. It is not interchangeable with other variants like MBRF7100 (100 V) or MBRF7150 (150 V).
Is MBRF790H qualified for automotive applications?
Yes, MBRF790H is explicitly AEC-Q101 qualified, as stated in the FEATURES section and Ordering Information notes of the Taiwan Semiconductor datasheet. The "H" suffix denotes this qualification, and the device meets stress test requirements for temperature cycling, humidity, and mechanical shock applicable to automotive under-hood and cabin electronics.
What is the forward voltage of MBRF790H at 7.5A and 125°C?
The forward voltage of MBRF790H is 0.82 V at 7.5 A and 125°C junction temperature, per the Electrical Specifications table in the datasheet. This value reflects real-world conduction loss under thermal stress and is critical for calculating power dissipation in high-ambient-temperature applications such as automotive engine control units.
Does MBRF790H have an isolated package?
Yes, MBRF790H uses the ITO-220AC package, where the metal tab is electrically isolated from the internal die. This is confirmed in the Mechanical Data section and Package Outline Dimensions page of the datasheet. The isolation allows direct mounting to a heatsink without requiring a thermal pad or insulator, simplifying thermal design in space-constrained layouts.
What is the maximum surge current rating for MBRF790H?
The MBRF790H has a non-repetitive peak forward surge current (IFSM) rating of 150 A for an 8.3 ms single half-sine wave, as specified in the Absolute Maximum Ratings table. This rating applies under conditions of superimposed surge on rated DC load and is validated per JEDEC standards for robustness in power supply turn-on and fault scenarios.
