1N485B Description

Short technical summary and product information.

The 1N485B is a small signal diode manufactured by onsemi (formerly ON Semiconductor). It is designed for general purpose rectification and switching applications where compact through-hole packaging is required. The device offers a maximum repetitive reverse voltage (VRRM) of 200V and an average rectified forward current (IF(AV)) of 200mA. Forward voltage is specified at 1.0V under a test condition of 100mA forward current.

 

The diode features a non-repetitive peak forward surge current rating of 1.0A for a 1 second pulse width and 4.0A for a 1 microsecond pulse width. Power dissipation is rated at 500mW with a thermal resistance (junction to ambient) of 300°C/W. The operating junction temperature maximum is 175°C, with a storage temperature range of -65°C to +200°C.

 

The 1N485B is housed in a JEDEC DO-35 (DO-204AH) axial lead package. The cathode is identified by a color band. The device is Pb-Free and Halide Free, and is available in bulk bag (5000 units) or tape and reel (10000 units) packaging options.
