2N718A TIN/LEAD is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Central Semiconductor Corp. Its product description is 750MA 500MW TH TRANSISTOR-SMALL. Review the specifications below when checking this part for your BOM.
The Central Semiconductor Corp 2N718A is a small-signal NPN silicon bipolar junction transistor designed for low-power applications. It features a collector-emitter voltage of 30 V and a continuous collector current of 500 mA. The device operates within a temperature range of -55 °C to +175 °C and is qualified under MIL-PRF-19500/181 standards. Packaged in the TO-18 (TO-206AA) metal can with three pins, it offers a maximum power dissipation of 0.5 W at 25 °C ambient temperature.
Verify that the specific order includes the tin/lead plating variant, as lead-free alternatives may exist within the same family. Confirm the presence of the MIL-PRF-19500/181 qualification mark on documentation. Ensure compatibility with existing through-hole mounting infrastructure due to the TO-18 package style. Request full datasheet details regarding DC current gain ranges before finalizing integration into critical designs.
Select this component when military-grade reliability and radiation hardness are required for space-constrained designs. The TO-18 package provides superior thermal conductivity compared to plastic equivalents. Consider the 30 V collector-emitter rating for low-voltage logic interfacing. Evaluate the 500 mA current limit against peak load requirements to ensure safe operating area compliance during transient conditions.
This part belongs to the 2N718 series of NPN transistors manufactured by Central Semiconductor. It shares functional similarities with other military-qualified small-signal devices but is distinct in its specific voltage and current ratings. The TO-18 package is a legacy standard often retained for high-reliability applications where hermetic sealing is mandatory.
Public confirmed substitute part numbers: 2N1613, 2N1613L.
