Product details
Overview
MBRF5100 from Taiwan Semiconductor is a 5A, 100V Schottky barrier rectifier in ITO-220AC package, featuring low forward voltage (0.90 V max at 5A/25°C), 120A surge capability, and AEC-Q101 qualification option. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the MBRF5100 datasheet, MBRF5100 pinout, MBRF5100 application, or MBRF5100 equivalent, key selection criteria include its 100V VRRM rating, 3°C/W junction-to-case thermal resistance, guard-ring overvoltage protection, and compatibility with lead-free reflow soldering per J-STD-002.
Technical Context
The MBRF5100 uses a single-die Schottky structure optimized for low conduction loss and fast switching, with no reverse recovery charge. Its guard ring design enhances ruggedness against transient overvoltage events common in automotive load-dump conditions.
Thermally, it delivers 3°C/W RθJC into the heatsink via the metal tab, enabling stable 5A continuous operation up to 125°C junction temperature when properly mounted with ≤0.56 N·m torque.

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-50SQ045 | 45V VRRM, 5A IF, TO-220AC package, VF = 0.52V typ @ 5A | Lower voltage rating limits use to sub-45V outputs; better efficiency at low VR but unsuitable for 100V systems | Select only if system VR ≤ 45V and lowest possible VF is critical |

FAQ
What is the maximum junction temperature rating for the MBRF5100?
The MBRF5100 has a maximum junction temperature (TJ) of +150°C, validated across its full operating range. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial settings when thermal design respects the 3°C/W RθJC limit and mounting torque does not exceed 0.56 N·m. Derating curves in the MBRF5100 datasheet confirm 5A continuous current is sustainable up to 125°C case temperature.
Is the MBRF5100 pin-compatible with other ITO-220AC Schottky rectifiers?
Yes-the MBRF5100 uses standard ITO-220AC pinout (Anode–Cathode–Isolated Tab) and mechanical footprint, matching industry-standard layouts for TO-220 variants. However, electrical compatibility depends on VRRM and VF requirements: the MBRF5100's 100V rating and 0.90V max VF differ from lower-voltage alternatives like VS-50SQ045, so system-level validation is required before substitution.
Does the MBRF5100 have AEC-Q101 qualification?
The base MBRF5100 is not AEC-Q101 qualified, but the MBRF5100H variant is explicitly qualified per AEC-Q101 Rev D. The "H" suffix denotes full stress testing including HTGB, HTRB, and temperature cycling. For automotive applications requiring qualification evidence, specify MBRF5100H-not MBRF5100-to ensure compliance documentation and lot traceability are provided.
What is the reverse leakage current specification for the MBRF5100 at elevated temperature?
At 125°C junction temperature and rated 100V reverse voltage, the MBRF5100 exhibits a maximum reverse leakage current (IR) of 5 mA. At 25°C, the limit is 100 µA. This temperature-dependent leakage behavior is typical for Schottky diodes and must be accounted for in low-power standby circuits where microamp-level leakage is critical to meet regulatory sleep-mode limits.
How does the guard ring feature improve reliability in the MBRF5100?
The guard ring in the MBRF5100 mitigates electric field crowding at the die periphery, preventing premature avalanche breakdown during voltage transients such as load dump or inductive switching spikes. This structural enhancement increases the device's ability to withstand repetitive 100V+ surges without degradation-directly supporting robust operation in automotive and industrial power systems where unclamped transients are common.
