1PGSMA4741HR3G

Single Zener Diodes Overview

The 1PGSMA4741HR3G is a surface-mount Zener diode from the 1PGSMA series by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 11 V with a tolerance of ±5%, operating within a range of 10.5 V to 11.6 V at a test current of 23 mA. The device is housed in a DO-214AC (SMA) package and supports a total power dissipation of 1 W at 75°C ambient temperature, derating above this threshold. It exhibits a maximum leakage current of 1 µA at its rated reverse voltage and maintains a junction temperature range from -55°C to +175°C.
