Microchip Technology's 1N943B is a temperature-compensated Zener diode designed for precision voltage regulation. This through-hole component, housed in a DO-7 (DO-204AA) package, offers a nominal Zener voltage of 11.7 V with a tight tolerance of ±5%. With a maximum power dissipation of 500 mW, it provides a stable reference voltage across a wide operating temperature range of -65°C to 175°C. Key electrical characteristics include a low reverse leakage current of 15 µA at 8 V and a maximum Zener impedance (Zzt) of 30 Ohms. This device is suitable for applications requiring stable voltage references in industrial control, test and measurement equipment, and power supply circuits.
