CDLL4620 Description

Short technical summary and product information.

The CDLL4620 is a Zener diode from Microchip Technology designed for low current operation at 250 µA. It features a nominal Zener voltage of 3.3V with ±5% tolerance and a maximum Zener impedance of 1650 Ω at 250 µA. The device is housed in a hermetically sealed glass DO-213AA (MELF, SOD-80, LL34) surface mount package with tin/lead lead finish.

 

Electrical characteristics include a maximum forward voltage of 1.1V at 200 mA, reverse leakage current of 7.5 µA at 1.5V, and a maximum DC Zener current of 85 mA. The diode can dissipate up to 500mW at an end cap temperature of +125°C, with a derating factor of 10 mW/°C above that temperature.

 

The operating temperature range spans -65°C to +175°C. Thermal resistance from junction to end cap is 100 °C/W maximum, and thermal impedance is 35 °C/W maximum. The device is RoHS3 compliant and has an MSL rating of 1 (unlimited).
