1N5940BRLG Description

Short technical summary and product information.

The 1N5940BRLG is a 43V Zener diode from onsemi's 1N5913B series, designed for voltage regulation in through-hole applications. It offers a maximum power dissipation of 3W at a lead temperature of 75°C, with a derating factor of 24 mW/°C above 75°C. The device provides a nominal Zener voltage of 43V with ±5% tolerance and a maximum impedance of 53 Ω at the Zener test current.

 

This diode features a high ESD rating of Class 3 (>16 kV) per the Human Body Model, making it suitable for environments where electrostatic discharge protection is critical. It also offers a surge power rating of 98 W for 1 ms, ensuring robustness under transient conditions. The operating temperature range spans -65°C to +200°C, allowing use in extreme thermal environments.

 

The 1N5940BRLG is housed in a DO-204AL (DO-41) axial lead plastic package, which is void-free and transfer-molded for environmental protection. The leads are corrosion-resistant and solderable, with a maximum soldering temperature of 260°C for 10 seconds. The device is available in tape and reel packaging with 6000 units per reel.
