TZMC43-GS08 Description

Short technical summary and product information.

The Vishay TZMC43-GS08 is a small signal Zener diode from the TZM series, designed for voltage stabilization applications. It features a nominal zener voltage of 43V with a tolerance of ±5%, providing a voltage range of 40.85V to 45.15V. The device can dissipate up to 500mW of power and offers a low reverse leakage current of 100nA maximum at 33V.

 

Key electrical characteristics include a dynamic impedance of 90Ω maximum at the test current of 5mA, and a forward voltage of 1.5V maximum at 200mA. The diode is capable of operating over a wide temperature range from -65°C to 175°C, with a maximum junction temperature of 175°C.

 

Packaged in a surface mount SOD-80 MiniMELF package (also known as DO-213AC), the TZMC43-GS08 is suitable for automated assembly processes. The package weight is approximately 31mg and is rated with UL 94 V-0 flammability and MSL level 1 for moisture sensitivity. This diode is ideal for voltage regulation, overvoltage protection, and reference voltage generation in low-power circuits.
