Product details
Overview
MBRF1690 from Taiwan Semiconductor is a 16A, 90V Schottky barrier rectifier in ITO-220AC package, featuring low forward voltage (0.85 V at 16 A, 25°C), high surge current capability (150 A), and AEC-Q101 qualification option. It serves as primary output rectifier in high-efficiency DC/DC converters for automotive infotainment power supplies.
For engineers reviewing the MBRF1690 datasheet, MBRF1690 pinout, MBRF1690 application, or MBRF1690 equivalent, key selection criteria include its 90 V repetitive peak reverse voltage, 3 °C/W junction-to-case thermal resistance, 7.5 mA reverse leakage at 125°C, guard ring over-voltage protection, and UL Recognized status (E-326243).
Technical Context
This single-die Schottky rectifier uses platinum-silicide or similar barrier metallization to achieve low VF and fast switching with no minority-carrier storage delay. Its ITO-220AC package enables direct heatsink mounting via the metal tab, supporting continuous 16 A conduction at case temperatures up to 100°C when properly heatsinked.
The device's 10,000 V/µs critical dv/dt rating and built-in guard ring structure provide robust immunity against transient voltage spikes in switching regulator flyback and synchronous rectification topologies. Reverse leakage remains tightly controlled at ≤300 µA (25°C) and ≤7.5 mA (125°C) at rated 90 V VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF | 16 A continuous forward current - supports high-power SMPS output stages without forced air cooling |

| RθJC | 3 °C/W - enables >12 W dissipation with 36°C rise above heatsink at 100°C case limit |
| IR @ 90 V, 125°C | 7.5 mA - ensures stable regulation under high-temp automotive ambient conditions |
| TJ max | 150 °C - compatible with under-hood automotive temperature requirements |
Pinout & Package
ITO-220AC package: isolated metal tab (cathode), 3-terminal through-hole outline with center tab electrically connected to cathode. Mounting torque ≤0.56 N·m. Matte tin-plated leads, J-STD-002 solderable.

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-MBR1690CT | TO-220AB package, dual common-cathode configuration; VF = 0.82 V @ 16 A, 25°C | Requires board redesign for dual-diode layout; better suited for center-tapped transformer outputs | Select if dual-diode topology or lower VF at cost of larger footprint and higher leakage (1.2 mA @ 90 V, 125°C) |
| ON Semiconductor MBR1690CT | TO-220AB, dual cathode; VF = 0.84 V @ 16 A, 25°C; AEC-Q101 qualified standard | Same dual-diode form factor; tighter IR spec (≤500 µA @ 90 V, 25°C) but higher cost | Choose when AEC-Q101 compliance is mandatory and dual configuration aligns with existing schematic |
Compared with MBRF1690, VS-MBR1690CT offers slightly lower VF but demands PCB layout changes and exhibits higher high-temp leakage, while MBR1690CT delivers guaranteed AEC-Q101 qualification and tighter room-temp leakage-both require evaluation for single-vs-dual diode functional fit in the target circuit.

FAQ
What is the maximum junction temperature rating for the MBRF1690?
The MBRF1690 has a maximum junction temperature (TJ max) of +150°C, validated across its full operating range. This rating allows the MBRF1690 to operate reliably in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 85°C. Derating curves confirm sustained 16 A conduction is possible up to 100°C case temperature when mounted on an adequate heatsink.
Is the MBRF1690 pin-compatible with other devices in the MBRF16xx family?
Yes-the MBRF1690 shares identical ITO-220AC package dimensions, terminal layout, and mounting interface with all MBRF16xx variants (e.g., MBRF1635, MBRF16150). Pinout, thermal pad connectivity, and mechanical mounting torque (≤0.56 N·m) are fully consistent across the family, enabling voltage-rating swaps without PCB revision.
Does the MBRF1690 have AEC-Q101 qualification?
The base MBRF1690 is not AEC-Q101 qualified; however, the AEC-Q101 qualified variant is designated MBRF1690H and carries the same electrical and thermal specifications. MBRF1690H undergoes extended stress testing per JESD47, including temperature cycling, HTRB, and ESD, and is marked with "H" suffix per ordering code conventions.
What is the forward voltage drop of the MBRF1690 at elevated temperature?
At 16 A and 125°C junction temperature, the MBRF1690 exhibits a typical forward voltage of 0.75 V-lower than its 0.85 V value at 25°C due to the negative temperature coefficient of Schottky diodes. This behavior improves thermal stability in high-power applications, reducing runaway risk compared to Si PN diodes.
How does the guard ring feature improve reliability of the MBRF1690?
The guard ring in the MBRF1690 mitigates edge breakdown under high dv/dt stress by controlling electric field distribution at the silicon periphery. This allows the MBRF1690 to sustain 10,000 V/µs critical rate-of-rise without avalanche initiation-critical for reliable operation in fast-switching flyback and LLC resonant converters where voltage overshoots commonly occur.
