Product details
Overview
MBR30H100CT from Taiwan Semiconductor is a dual-die AEC-Q101-qualified Schottky barrier rectifier in TO-220AB package, rated for 30A average forward current, 100V repetitive peak reverse voltage, and 150A surge capability-used in high-efficiency DC/DC converters and automotive-grade SMPS.
For engineers reviewing the MBR30H100CT datasheet, MBR30H100CT pinout, MBR30H100CT application, or MBR30H100CT equivalent, key selection criteria include junction-to-case thermal resistance (2°C/W), low VF at 30A (0.98V @ 25°C), temperature-stable reverse leakage (<2mA @ 125°C), and guard-ring-enabled overvoltage protection.
Technical Context
This dual-die Schottky rectifier integrates two independent 30A/100V diodes in a single TO-220AB thermally optimized package with matte tin-plated leads. Its design targets high-frequency switching topologies where low forward voltage drop and fast recovery minimize conduction loss and EMI generation.
The device features a guard ring structure to suppress edge breakdown, supports 10,000 V/μs critical dv/dt rating, and maintains stable performance across -55°C to +175°C junction temperature range-enabling use in under-hood automotive power supplies and industrial DC/DC modules.

FAQ
What is the maximum junction temperature rating for the MBR30H100CT?
The MBR30H100CT has a maximum junction temperature (TJ max) of +175°C, validated per JEDEC standards. This rating enables reliable operation in engine bay or sealed industrial enclosures where ambient temperatures exceed 105°C. Derating curves in the datasheet define safe IF limits above 125°C case temperature, and the device maintains stable VF and IR performance up to its full TJ range.
Is the MBR30H100CT pin-compatible with standard TO-220AB rectifiers?
Yes, the MBR30H100CT uses the industry-standard TO-220AB mechanical outline with 3 terminals in left–center–right configuration. Terminal 1 is Anode 1, Terminal 2 is common Cathode (electrically tied to the tab), and Terminal 3 is Anode 2. Mounting hole spacing, lead pitch, and tab dimensions match JEDEC TO-220AB specifications, ensuring compatibility with existing heatsinks and footprints.
Does the MBR30H100CT have AEC-Q101 qualification, and what does that cover?
Yes, the MBR30H100CT is AEC-Q101 qualified-specifically the "H" suffix variant (MBR30H100CT). This certification covers stress testing for temperature cycling, humidity bias, high-temperature operating life, and mechanical shock, validating suitability for automotive power electronics. The qualification applies to the full device, including internal die attach, wire bonding, and molding compound.
What is the typical forward voltage drop of the MBR30H100CT at full rated current?
The MBR30H100CT exhibits a typical forward voltage (VF) of 0.98 V at 30 A and 25°C junction temperature, measured per diode. At elevated temperature (125°C), VF drops to 0.85 V due to Schottky's negative temperature coefficient-improving efficiency under thermal load. These values are confirmed under pulsed conditions (PW = 0.3 ms) to avoid self-heating artifacts.
How does the guard ring structure improve reliability in the MBR30H100CT?
The guard ring in the MBR30H100CT suppresses electric field crowding at the silicon periphery, preventing premature edge breakdown during transient overvoltage events. This allows the device to sustain its full 100V VRRM rating without derating, even under non-uniform voltage distribution-critical for robustness in unregulated input rails or flyback snubber circuits.
