DL4742A T/R Description

Short technical summary and product information.

The DL4742A T/R is a single Zener diode manufactured by Rectron Semiconductor Inc. It is designed for voltage regulation applications and features a nominal Zener voltage of 12V, with a maximum Zener voltage of 12.7V and a minimum of 11.4V at a test current of 10mA. The diode has a maximum power dissipation rating of 1W at 25°C and a maximum regulator current of 100mA.

This Zener diode is housed in an LL-41 (MELF) package, which is hermetically sealed glass with through-hole mounting. The construction is compression bonded, ensuring corrosion resistance and solderable leads. The operating junction temperature can reach up to 200°C, with a storage temperature range of -65°C to 200°C.

Key electrical characteristics include a maximum Zener impedance of 10Ω at 10mA and 700Ω at 0.25mA. The maximum reverse leakage current is 10µA at 11.4V. The typical forward voltage is 1V at 100mA.

This component is suitable for various electronic circuits requiring stable voltage references or regulation. Its through-hole mounting makes it convenient for breadboarding and through-hole PCB assembly.
