BAS29 Description

Short technical summary and product information.

The BAS29 is a general-purpose small signal diode designed for high-speed switching applications. Manufactured by On Semiconductor, this diode offers a maximum repetitive reverse voltage of 120 V and an average rectified forward current of 200 mA.

 

Key electrical characteristics include a low forward voltage of 1.0 V maximum at 200 mA, reverse leakage current of 100 nA at 90 V, and a fast reverse recovery time of 50 ns. The device also features a junction capacitance of 2.0 pF at 0 V and 1 MHz, making it suitable for high-frequency switching circuits.

 

The BAS29 is housed in a surface mount SOT-23-3 package, compliant with lead-free and halogen-free standards. It has a power dissipation of 350 mW and a junction-to-ambient thermal resistance of 357 °C/W. The operating junction temperature ranges up to 150 °C, with a storage temperature range of -55 °C to +150 °C.

 

Typical applications include general purpose switching, signal rectification, reverse polarity protection, and low-power rectification in portable and consumer electronics. Its compact package and robust electrical performance make it a reliable choice for space-constrained designs.
