Taiwan Semiconductor Corporation 1PGSMA4742-R3G is a 1.25W Zener diode with a nominal breakdown voltage of 12V and a tolerance of ±5%. This component features a low reverse leakage current of 1 µA at 9.1V and a maximum impedance of 9 Ohms. Designed for efficient power dissipation, it operates reliably across a wide temperature range of -55°C to 175°C (TJ). The diode is housed in a compact DO-214AC (SMA) surface-mount package, supplied on tape and reel for automated assembly. Its forward voltage drop is 1.2V at 200mA. This component is suitable for voltage regulation and transient suppression applications in automotive, industrial, and consumer electronics.
