2.7V 0.5Watt Zener Diode 275-ZD

The 1N5223B is a 2.7V, 0.5W silicon planar Zener diode manufactured by Taiwan Semiconductor for low-voltage reference clamping and power management circuits. Housed in a compact, hermetically sealed DO-35 glass package, this through-hole component provides a standard tight breakdown voltage tolerance of 5%. It operates at a nominal Zener voltage of 2.7V under a 20 mA test current while presenting a maximum dynamic loop impedance of 30 ohms. Engineered for stable voltage performance in space-limited designs, this robust device operates reliably across a wide temperature range from minus 65 to plus 175 degrees Celsius.
