Product details
Overview
MBR30L100CT from Taiwan Semiconductor is a 30A, 100V low forward-voltage dual-die Schottky barrier rectifier in TO-220AB package, designed for high-efficiency DC/DC conversion and SMPS output rectification with 0.77V max VF at 15A/25°C and 32mA reverse leakage at 100V/125°C.
For engineers reviewing the MBR30L100CT datasheet, MBR30L100CT pinout, MBR30L100CT application, or MBR30L100CT equivalent, this page delivers verified electrical specs, thermal resistance (1°C/W), surge rating (220A), AEC-Q101 qualification path, and real-world use context in automotive-grade power supplies and industrial adapters.
Technical Context
This dual-die Schottky rectifier integrates two independent 30A/100V junctions in a single TO-220AB case with common-cathode configuration. Its 0.77V max forward voltage at 15A/25°C and 32mA IR at 100V/125°C enable reduced conduction loss in high-frequency switching topologies.
The device features guard ring overvoltage protection, 10,000 V/μs dv/dt rating, and 1°C/W junction-to-case thermal resistance-supporting reliable operation up to 150°C junction temperature in thermally constrained layouts.

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-30CPH10-M3 | Same 30A/100V rating; VF = 0.75V @ 15A/25°C; TO-247AC package; higher RθJC (1.5°C/W) | Requires larger heatsink area due to lower thermal conductivity; better surge margin (250A IFSM) | Select for higher surge robustness where board space allows TO-247 footprint |
| ON Semiconductor MBR30H100CT | Identical TO-220AB package; VF = 0.78V @ 15A/25°C; AEC-Q101 qualified as standard (no -H suffix needed) | Pre-qualified for automotive use; slightly higher VF increases conduction loss by 0.01V | Select when AEC-Q101 compliance is mandatory and qualification documentation is required upfront |
Compared with VS-30CPH10-M3 and MBR30H100CT, the MBR30L100CT offers optimal thermal performance (1°C/W) in TO-220AB, making it preferred for space-constrained industrial adapters where heatsink mass must be minimized.

FAQ
What is the maximum junction temperature rating for the MBR30L100CT?
The MBR30L100CT has a maximum junction temperature (TJ max) of +150°C, enabling operation in high-ambient environments such as under-hood automotive modules or enclosed industrial power supplies. This rating is validated per JEDEC standards and supported by its 1°C/W junction-to-case thermal resistance, allowing direct heatsink mounting without thermal interface material in many designs.
Is the MBR30L100CT AEC-Q101 qualified?
The MBR30L100CT itself is not AEC-Q101 qualified; however, the pin-compatible MBR30L100CTH variant-identical in all electrical and mechanical specifications-is fully AEC-Q101 qualified. Customers requiring automotive-grade reliability must specify the "H" suffix in the ordering code to receive the qualified version.
What is the forward voltage of the MBR30L100CT at elevated temperature?
At 15A and 125°C junction temperature, the MBR30L100CT exhibits a typical forward voltage of 0.67V, with a maximum specified value not provided-only the 25°C max of 0.77V is guaranteed. This temperature-dependent VF reduction improves efficiency stability in thermally dynamic applications like laptop adapters during sustained load.
Does the MBR30L100CT have a common-cathode or common-anode configuration?
The MBR30L100CT uses a common-cathode configuration: Pin 2 is the shared cathode terminal, while Pins 1 and 3 serve as independent anodes. This layout supports full-wave rectification from center-tapped transformers and simplifies PCB routing in dual-output or redundant power architectures.
What packaging and quantity options are available for the MBR30L100CT?
The MBR30L100CT is supplied in TO-220AB package, packed 50 units per tube. Tape-and-reel (TR) packaging is not offered for this part number; only tube format is available per Taiwan Semiconductor's ordering information. Lead finish is matte tin, compliant with J-STD-002 solderability requirements.
