The 1N5941B is a 47V Zener voltage regulator diode from On Semiconductor's 1N5913B series. It is designed for through-hole mounting in an axial lead DO-204AL (DO-41) package and offers a maximum power dissipation of 3W at a lead temperature of 75°C (derated to 1W at 50°C ambient). The part features a nominal Zener voltage of 47V with a ±5% tolerance. Maximum Zener impedance is 67 Ω at the Zener test current. The diode provides a maximum forward voltage of 1.5V at 200 mA forward current, and maximum reverse leakage current of 1 µA at 35.8V.
The device is built with a silicon-oxide passivated junction for reliable operation over a wide temperature range of -65°C to +200°C. It is housed in a void-free, transfer-molded thermosetting plastic case that provides environmental protection. The cathode is indicated by a polarity band.
Designed for general-purpose voltage regulation, the 1N5941B serves applications requiring a stable 47V reference. Its rugged construction and surge rating (98W @ 1ms per datasheet) make it suitable for power supply and clamping circuits. Pb-Free package options are available as noted in the datasheet.
