1N5370BRLG Description

Short technical summary and product information.

The 1N5370BRLG is a 56V Zener diode from On Semiconductor, part of the 1N53 series of 5W Surmetic 40 voltage regulators. It features a 5W power dissipation capability with a derating factor of 40 mW/°C above 25°C. The device offers a surge rating of 180W at 8.3 ms and an ESD rating of Class 3 (>16 kV) per HBM. The Zener voltage is 56V with a tolerance of ±5%, and typical forward voltage is 1.2V at 1A. The junction-to-lead thermal resistance is 25°C/W. The diode is housed in an axial lead, transfer-molded plastic package suitable for through-hole mounting. It has an operating temperature range of -65°C to 200°C and is rated for lead soldering at 260°C for 10 seconds. The 1N5370BRLG is RoHS compliant and REACH unaffected, with Pb-Free available options. It is suitable for voltage regulation, overvoltage protection, and clamping applications in various electronic circuits.
