Overview
The HCT700 is a hermetically sealed complementary switching transistor pair in a ceramic surface mount package. It features silicon planar epitaxial NPN and PNP transistors with electrical characteristics similar to the 2N2222A and 2N2907A, respectively. The device supports an NPN collector-emitter voltage of 50V and a PNP voltage of 60V. Continuous collector currents are rated at 800mA for NPN and 60mA for PNP. Power dissipation reaches 2.0W at a substrate temperature of 25°C. The unit operates within a temperature range of -65°C to +200°C.
Feature Summary

Procurement Notes
Verify specific screening requirements such as CECC standards or space quality levels when ordering. Confirm pinout alignment with LCC2 package dimensions. Ensure thermal management accounts for derating above 25°C. Check soldering temperature limits for vapor phase or heated collet processes. Validate component authenticity through authorized channels.
Selection Notes
Select this component for designs requiring hermetic sealing and radiation tolerance. Compare NPN and PNP current ratings against load requirements. Consider thermal resistance values for heat dissipation planning. Evaluate package compatibility with automated assembly equipment. Review breakdown voltages for circuit safety margins.
Part Context
Manufactured by Semelab plc, the HCT700 belongs to a family of high-reliability discrete semiconductors. It serves as a robust alternative to standard plastic-packaged transistors in harsh environments. The device integrates both NPN and PNP functions into a single compact footprint.
Replacement Considerations
Direct replacements include components matching the 2N2222A/2N2907A electrical profiles in hermetic packages. Verify pinout compatibility with the LCC2 configuration. Ensure equivalent power dissipation and voltage ratings are met.
