Product details
Overview
MBRF30L120CT from Taiwan Semiconductor is a dual-die, low-forward-voltage Schottky barrier rectifier in ITO-220AB package, rated for 30A average forward current and 120V repetitive peak reverse voltage, with 0.89V max VF at 30A/25°C and 200A surge capability - deployed in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the MBRF30L120CT datasheet, MBRF30L120CT pinout, MBRF30L120CT application, or MBRF30L120CT equivalent, key selection factors include thermal resistance (5°C/W), AEC-Q101 qualification availability (MBRF30L120CTH), junction temperature range (–55°C to +150°C), and low VF performance across temperature.
Technical Context
This device integrates two independent Schottky diodes in a common-cathode configuration within a single ITO-220AB thermally enhanced package, enabling synchronous rectification or dual-output DC-DC topologies. Its guard ring structure provides overvoltage protection, and it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.
The MBRF30L120CT delivers stable low VF down to 0.76V (typ) at 30A/125°C, supporting high-efficiency operation in thermally constrained environments. With dv/dt rating of 10,000 V/µs and 25 mA max reverse leakage at 125°C, it sustains reliable switching in fast transient power stages.

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-30CPH12 | Same ITO-220AB package, 30A/120V, but VF = 0.92V max @ 30A/25°C; no AEC-Q101 option | Lacks automotive qualification; lower surge rating (175A vs. 200A) | Preferred for cost-sensitive industrial adapters where AEC-Q101 is not required |
| ON Semiconductor MBR30H120CT | Identical electrical specs and package; AEC-Q101 qualified; VF = 0.90V max @ 30A/25°C | Direct functional match with broader automotive support documentation | Best alternative when cross-manufacturer validation is needed for Tier-1 automotive programs |
Compared with VS-30CPH12 and MBR30H120CT, the MBRF30L120CT offers the lowest VF among the three at high temperature (0.76V typ @ 30A/125°C), making it optimal for thermally demanding, high-efficiency applications where junction temperature routinely exceeds 100°C.

FAQ
What is the maximum junction temperature rating for the MBRF30L120CT?
The MBRF30L120CT has a maximum junction temperature (TJ MAX) of +150°C, with operational range from –55°C to +150°C. This rating enables use in high-ambient-temperature applications such as enclosed industrial power supplies and automotive under-hood auxiliary converters. The MBRF30L120CT maintains specified electrical performance across this full range when thermal design respects the 5°C/W junction-to-case resistance.
Does the MBRF30L120CT have AEC-Q101 qualification?
The base MBRF30L120CT is not AEC-Q101 qualified; however, the MBRF30L120CTH variant - identical in all electrical and mechanical specifications - is fully AEC-Q101 qualified. Both share the same ITO-220AB package and marking code prefix, differing only in qualification status and packing label. Engineers selecting for automotive applications must specify MBRF30L120CTH to ensure compliance.
What is the forward voltage drop of the MBRF30L120CT at 30A and 125°C?
At 30A forward current and 125°C junction temperature, the MBRF30L120CT exhibits a typical forward voltage (VF) of 0.76V, with a maximum of 0.82V. This low, temperature-stable VF - significantly lower than silicon rectifiers - directly reduces conduction losses in high-temperature operating conditions, improving overall system efficiency and thermal margin in DC-DC converters.
How is the pin configuration arranged in the MBRF30L120CT ITO-220AB package?
The MBRF30L120CT uses a 3-pin ITO-220AB package with Anode 1, Anode 2, and Common Cathode terminals. The cathode tab is electrically and thermally connected to the metal backplate, intended for direct heatsink mounting. Pin identification follows standard ITO-220AB orientation: left pin (Anode 1), center pin (Anode 2), right tab (Common Cathode), with polarity marked on the device body.
What packaging and compliance certifications apply to the MBRF30L120CT?
The MBRF30L120CT is supplied in tubes of 50 units per tube and complies with RoHS Directive 2011/65/EU and IEC 61249-2-21 halogen-free requirements. It carries UL Recognition File #E-326243 and meets JESD201 Class 2 whisker testing. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated per J-STD-002 solderability standards.
