1N5378BG Description

Short technical summary and product information.

The 1N5378BG is a 5 W Zener voltage regulator diode from the 1N53 series, manufactured by On Semiconductor. It offers a nominal Zener voltage of 100 V with a ±5% tolerance. The device features a maximum impedance (Zzt) of 90 Ω and a low reverse leakage current of 500 nA at 76 V. It can handle surge power up to 180 W at 8.3 ms and has an ESD rating of Class 3 (>16 kV) per the Human Body Model. The diode is housed in a void-free, transfer-molded thermosetting plastic T-18 axial lead package. It is designed for through-hole mounting and can operate over a temperature range of -65°C to 200°C, with a maximum DC operating temperature of 150°C. The part is Pb-Free (indicated by the G suffix) and is RoHS3 compliant according to the datasheet.
