Product details
Overview
MBRF30100CT-Y from Taiwan Semiconductor is a 30A dual-die Schottky barrier rectifier in ITO-220AB package, rated for 100V repetitive peak reverse voltage (VRRM), 0.94V max forward voltage at 30A/25°C, and 200A surge current capability - used as output rectification in high-efficiency DC-DC converters.
For engineers reviewing the MBRF30100CT-Y datasheet, MBRF30100CT-Y pinout, MBRF30100CT-Y application, or MBRF30100CT-Y equivalent, key selection criteria include VRRM=100V, IF=30A continuous, VF≤0.94V @30A/25°C, TJ(max)=150°C, and ITO-220AB thermal performance (RθJC=4°C/W).
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 30A diodes in a single ITO-220AB thermally optimized package, enabling synchronous or interleaved output rectification without external paralleling. Its low VF and 10,000 V/µs dv/dt rating support high-frequency switching topologies up to 20 kHz.
The device features guard ring overvoltage protection, meets JESD201 Class 1A whisker resistance, and uses matte tin-plated leads compliant with J-STD-002 solderability - critical for industrial power supply reflow and wave soldering reliability.
Key Specifications

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-30CPH100 | VRRM=100V, IF=30A, VF=0.87V@30A/25°C, TO-247AC package, RθJC=3.5°C/W | Higher thermal efficiency but larger footprint; requires different mounting hardware | Select when lower thermal resistance outweighs PCB area constraints |

FAQ
What is the maximum junction temperature rating for MBRF30100CT-Y?
The MBRF30100CT-Y has a maximum junction temperature (TJ(max)) of 150°C, validated per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version E2105. This rating allows reliable operation in industrial environments with ambient temperatures up to 85°C when properly heatsinked. Derating curves in Figure 1 confirm usable current capacity down to 15A at 125°C case temperature. The MBRF30100CT-Y must not be operated beyond this limit to avoid irreversible parametric shift or bond wire failure.
Does MBRF30100CT-Y support dual independent outputs?
Yes, the MBRF30100CT-Y contains two independent Schottky diodes sharing a common cathode (dual-common-cathode configuration), with separate anode terminals (Tab and Lead 1). This enables true dual-output rectification - for example, generating +12V and –12V rails from a center-tapped transformer, or splitting load current across two windings. The MBRF30100CT-Y's pinout and internal die isolation support such configurations without cross-conduction or thermal coupling penalties.
What is the forward voltage specification for MBRF30100CT-Y at full rated current?
The MBRF30100CT-Y specifies a maximum forward voltage (VF) of 0.94 V per diode at IF = 30 A and TJ = 25°C, per Electrical Specifications Table on page 2 of the Taiwan Semiconductor datasheet. At elevated temperature (TJ = 125°C), VF drops to 0.82 V max under the same current - a characteristic of Schottky diodes that improves thermal stability in high-ambient applications. The MBRF30100CT-Y's low VF directly reduces conduction losses in high-current output stages.
Is MBRF30100CT-Y compatible with lead-free reflow soldering processes?
Yes, the MBRF30100CT-Y features matte tin-plated leads qualified per J-STD-002 for solderability, and its ITO-220AB package withstands standard lead-free reflow profiles (peak temperature ≤260°C, 60-second duration above 217°C). The UL 94V-0 molding compound remains dimensionally stable during thermal cycling. Taiwan Semiconductor confirms the MBRF30100CT-Y is fully compatible with IPC-J-STD-020-compliant assembly processes - no special prebake or flux requirements are needed for the MBRF30100CT-Y.
What packaging format is used for MBRF30100CT-Y shipments?
The MBRF30100CT-Y is supplied in tubes containing 50 units each, as specified in the Ordering Information section of the Taiwan Semiconductor datasheet. Each tube is labeled with date code (YWW), factory code (F), and green compound indicator (G). Tape-and-reel packaging is not offered for this variant. Aetrix Electronics maintains tube-based inventory and can support both prototype sampling and production-volume orders of the MBRF30100CT-Y without minimum order quantity restrictions.
