The ±2% tolerance on the nominal Zener voltage is tighter than the common 5% or 10% grades, which matters when the shunt reference sets a supply rail or ADC bias voltage that cannot drift more than 150 mV over temperature and load. Maximum Zener impedance (Zzt) is 4 Ohms at the test current — a low dynamic resistance that keeps the output voltage stable as the load current varies within the 1 W dissipation budget. ## Wide temperature range and reverse leakage Reverse leakage current is specified at 10 µA maximum at 5 V reverse voltage — a guard-band figure that confirms the diode blocks cleanly below the Zener knee. Maximum forward voltage is 1.2 V at 200 mA forward current, typical for a silicon Zener in this power class. The Tape & Reel suffix (/TR8) signals reel quantity packaging for automated pick-and-place assembly; the same die is also available in bulk or ammo-pack variants under the base number 1N4737.","metaTitle":"Microchip 1N4737CP/TR8 Zener Diode, 7.5 V, 1 W, DO-41","metaDescription":"Microchip Technology 1N4737CP/TR8 Zener diode, 7.5 V nominal, ±2% tolerance, 1 W power dissipation.
