Product details
Overview
MBR30100CT from Taiwan Semiconductor is a 30A dual-die Schottky barrier rectifier in TO-220AB package, rated for 100V repetitive peak reverse voltage (VRRM), 200A surge current (IFSM), and maximum junction temperature of 150°C; it delivers low forward voltage (0.84V typ. @ 15A, 25°C) and is used in high-efficiency DC/DC converters and industrial SMPS.
For engineers reviewing the MBR30100CT datasheet, MBR30100CT pinout, MBR30100CT application, or MBR30100CT equivalent, key selection criteria include VRRM=100V, IF=30A continuous, VF≤0.94V @ 30A/25°C, RθJC=1.5°C/W thermal resistance, and AEC-Q101 qualification availability (H-suffix variant).
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 30A diodes in a single TO-220AB thermally optimized package, enabling synchronous or parallel rectification in center-tapped or full-wave bridge topologies. Its guard ring structure provides overvoltage protection, and the 10,000 V/μs dv/dt rating supports fast-switching converter operation.
Designed for high-reliability power conversion, the device exhibits low leakage (IR ≤ 200 µA @ 25°C, ≤7.5 mA @ 125°C) and stable forward voltage across temperature - 0.70V–0.94V at 30A depending on junction temperature - ensuring predictable conduction loss in thermal-limited designs.
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-30CPH10 | Same TO-220AB package, 30A/100V, VF = 0.82V @ 30A/25°C, RθJC = 1.4°C/W; no AEC-Q101 option | Preferred for non-automotive telecom and computing where lower VF improves light-load efficiency | Select when prioritizing marginally lower conduction loss and higher thermal conductivity over automotive qualification |
| ON Semiconductor MBR30H100CT | TO-220AB, 30A/100V, VF = 0.85V @ 30A/25°C, RθJC = 1.5°C/W; AEC-Q101 qualified, halogen-free | Drop-in replacement for automotive designs requiring same footprint and qualification level | Choose when full AEC-Q101 compliance and identical thermal performance are mandatory |
Compared with MBR30100CT, VS-30CPH10 offers slightly better thermal resistance but lacks automotive qualification, while MBR30H100CT matches its thermal and qualification profile exactly - making it a direct AEC-Q101-compliant alternative where Taiwan Semiconductor's supply chain constraints apply.

FAQ
What is the maximum junction temperature rating for MBR30100CT?
The MBR30100CT has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version K2104). This rating applies under continuous operation with appropriate heatsinking and accounts for thermal derating curves shown in Figure 1. The device remains fully functional within this limit, and exceeding it risks permanent degradation of the Schottky junction.
Does MBR30100CT have AEC-Q101 qualification?
The base MBR30100CT is not AEC-Q101 qualified; however, the MBR30100CTH variant - indicated by the "H" suffix in the ordering code - is explicitly qualified per AEC-Q101. This distinction is documented in the Ordering Information section (Page 4, Version K2104) and confirmed in the FEATURES list. For automotive applications, only MBR30100CTH should be selected.
What is the forward voltage of MBR30100CT at 30A and 25°C?
Per the Electrical Specifications table (Page 2, Version K2104), the maximum forward voltage (VF) of MBR30100CT is 0.94 V at IF = 30 A and TJ = 25°C. This value is measured per diode under pulsed conditions (PW = 0.3 ms), and represents the worst-case conduction loss for thermal design and efficiency calculations in high-current SMPS outputs.
How many diodes are integrated in the MBR30100CT package?
The MBR30100CT contains two independent Schottky diodes configured in a common-cathode arrangement inside a single TO-220AB package. This dual-die structure is confirmed in the KEY PARAMETERS section ("Configuration: Dual dies") and supported by the pinout (two anodes, one shared cathode), enabling full-wave or dual-output rectification without external paralleling.
What is the junction-to-case thermal resistance (RθJC) of MBR30100CT?
The junction-to-case thermal resistance (RθJC) of MBR30100CT is 1.5°C/W, as specified in the THERMAL PERFORMANCE table (Page 2, Version K2104) for the 100V and 150V variants. This value is critical for heatsink sizing and must be used with case temperature measurements to calculate actual junction temperature under load.
