Taiwan Semiconductor Corporation MBR7100 C0G

Overview

MBR7100 C0G from Taiwan Semiconductor is a 7.5A, 100V Schottky barrier rectifier in TO-220AC package, featuring 0.92V forward voltage at 7.5A/25°C, 150A surge capability, and AEC-Q101 qualification option. It serves as primary output rectifier in high-efficiency DC-DC converters for automotive infotainment power supplies.

For engineers reviewing the MBR7100 C0G datasheet, MBR7100 C0G pinout, MBR7100 C0G application, or MBR7100 C0G equivalent, key selection criteria include its 100V V_RRM, 0.92V V_F at rated current, thermal resistance (R_θJC = 5°C/W), and TO-220AC mechanical compatibility with standard heatsink mounting.

Technical Context

This single-die Schottky rectifier operates with junction temperatures from –55°C to +150°C and supports repetitive reverse voltages up to 100V. Its low forward voltage drop and high dV/dt rating (10,000 V/µs) enable stable operation in fast-switching topologies like synchronous buck converters.

The device uses guard ring structure for overvoltage protection and meets JESD201 Class 2 whisker resistance. With R_θJA = 15°C/W and R_θJC = 5°C/W, it delivers predictable thermal performance under continuous 7.5A conduction when mounted on a heatsink.

FAQ

What is the maximum junction temperature rating for MBR7100 C0G?

The MBR7100 C0G has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version K2103). This rating applies under continuous operation with proper heatsinking and defines the upper thermal limit for reliability modeling and derating calculations. Exceeding this temperature risks permanent degradation of the Schottky junction. The MBR7100 C0G must be operated within this limit to maintain specified electrical performance and lifetime.

Is MBR7100 C0G AEC-Q101 qualified?

The MBR7100 C0G itself is not automatically AEC-Q101 qualified; qualification applies only to variants marked with suffix "H" (e.g., MBR7100H). The "C0G" suffix denotes a specific date code and internal lot identifier-not qualification status. Engineers requiring automotive-grade reliability must specify MBR7100H and verify qualification documentation directly from Taiwan Semiconductor's certified test reports. The MBR7100 C0G shares identical die and package construction but lacks formal AEC-Q101 validation unless explicitly ordered as the "H" variant.

What is the forward voltage of MBR7100 C0G at 7.5A and 125°C?

The forward voltage (V_F) of MBR7100 C0G is 0.82 V when measured at 7.5A forward current and 125°C junction temperature, as confirmed in the Electrical Specifications table (page 2, Version K2103). This value reflects real-world thermal conditions in high-power-density designs and is critical for calculating conduction losses at elevated operating temperatures. The MBR7100 C0G maintains stable V_F characteristics across its full temperature range, supporting accurate thermal simulation.

Does MBR7100 C0G have a guard ring structure?

Yes, MBR7100 C0G incorporates a guard ring structure for overvoltage protection, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet (Version K2103). This design feature enhances edge termination robustness, preventing localized avalanche breakdown during transient voltage spikes. The guard ring contributes directly to the device's 10,000 V/µs dV/dt rating and improves long-term reliability in noisy switching environments. This structural element is integral to the MBR7100 C0G die layout and is not an optional add-on.

What is the reverse leakage current of MBR7100 C0G at 100V and 125°C?

The reverse leakage current (I_R) of MBR7100 C0G is 5 mA when tested at rated reverse voltage (100V) and junction temperature of 125°C, per the Electrical Specifications table (page 2, Version K2103). This parameter directly impacts standby power consumption in always-on systems and must be included in total system leakage budgets. The MBR7100 C0G exhibits lower I_R than lower-voltage variants in the same family, reflecting optimized doping and junction design for 100V operation.
