Technical Specifications Breakdown
The BSZ067N06LS3GATMA1 is an N-channel MOSFET built on an advanced silicon process. Its key specifications underscore its suitability for high-frequency, low-voltage switching:
Voltage and Current Ratings: It boasts a drain-source voltage (VDS) of 60 V and a continuous drain current (ID) of 50 A at a case temperature (TC) of 100°C. This robust current handling capability is essential for managing significant power levels.
Ultra-Low On-Resistance: A defining feature is its exceptionally low typical on-resistance (RDS(on)) of just 0.67 mΩ at a gate-source voltage (VGS) of 10 V. This minimal resistance is critical for reducing conduction losses, which directly translates to higher system efficiency and lower heat generation.
Superior Switching Performance: The device features low gate charge (QG) and low figures of merit (e.g., RDS(on) QG). These characteristics enable very fast switching speeds, which are paramount for minimizing switching losses in high-frequency circuits such as switch-mode power supplies (SMPS) and motor drives.
Enhanced Robustness and Protection: It offers a low thermal resistance and is qualified according to the highest quality standards, ensuring high reliability and durability under strenuous operating conditions.
Package: It is housed in a SuperSO8 (PG-TDSON-8) package. This package offers an excellent trade-off between compact size and thermal/electrical performance, facilitating high-power density designs.
Application Analysis
The combination of ultra-low RDS(on) and fast switching speed makes the BSZ067N06LS3GATMA1 exceptionally versatile. Its primary applications include:
Synchronous Rectification in SMPS: In server, telecom, and industrial power supplies (e.g., for 48V and 12V intermediate bus converters), this MOSFET is ideal for the synchronous rectification stage. Its low conduction losses directly boost the overall efficiency of the power supply unit (PSU).
Motor Control and Drives: It is perfectly suited for driving brushed and brushless DC motors in industrial tools, robotics, and automotive systems (e.g., electric power steering, pump controls). The high current capability and efficient switching allow for precise and powerful motor control.
DC-DC Converters: In both non-isolated point-of-load (POL) converters and high-step-down ratio converters, the device's performance helps achieve high efficiency across a wide load range, which is critical for modern computing and FPGA/ASIC power delivery.
Battery Management Systems (BMS) and Protection: Its low on-resistance makes it an excellent choice for load switches and protection circuits in battery-powered applications, minimizing voltage drop and power loss during operation.
ICGOOODFIND: The Infineon BSZ067N06LS3GATMA1 is a high-performance OptiMOS™ power MOSFET that sets a benchmark for efficiency and power density. Its industry-leading low on-resistance and excellent switching characteristics make it a superior choice for designers aiming to maximize performance in power conversion stages, particularly in synchronous rectification, motor drives, and advanced DC-DC converters.
