10MQ040NTR Description

Short technical summary and product information.

The 10MQ040NTR is a high performance Schottky rectifier from Vishay Semiconductors, designed for applications requiring low forward voltage drop and compact surface mount packaging. With an average rectified current rating of 1A at 50% duty cycle and TL=132°C, and a maximum DC reverse voltage of 40V, this diode is suitable for a variety of power management circuits. The forward voltage is typically 0.54V at 1A (25°C) and maximum 0.56V at 1.5A (125°C). Reverse leakage current is 26mA maximum at 125°C.

 

The device features a robust guard ring design for enhanced ruggedness and long term reliability, and it is capable of handling non-repetitive surge currents up to 120A for 5μs sine pulses and 30A for 10ms sine pulses. The non-repetitive avalanche energy rating is 3.0mJ. The operating junction temperature ranges from -55°C to +150°C.

 

Packaged in the industry-standard SMA (DO-214AC) surface mount package, the 10MQ040NTR is ideal for space-constrained designs. It is lead-free (PbF) and meets MSL level 1 per J-STD-020, with a maximum peak reflow temperature of 260°C. Typical applications include switching power supplies, converters, freewheeling diodes, battery charging, and reverse battery protection.
