Overview
The BCX71HT216 is a general-purpose PNP silicon epitaxial planar transistor manufactured by ROHM Semiconductor. It is designed for amplification applications and is supplied in an SST3 (SOT-23) surface-mount package. The device features a collector-emitter voltage of -45V, a collector current of -0.2A, and a collector power dissipation of 0.2W. The DC current gain (hFE) ranges from 140 to 630. It operates within a storage temperature range of -55°C to 150°C. This component is currently classified as not recommended for new designs.
Feature Summary
- General-purpose amplification capability using PNP silicon epitaxial planar technology
- Surface-mount construction in a compact SOT-23 package for automated assembly
- High DC current gain suitable for signal amplification tasks
Applications
- General purpose amplification circuits
- Switching applications requiring low current handling
Procurement Notes
Verify the specific ordering suffix HT216 against official documentation to confirm tape-and-reel packaging details. Confirm that the part status remains 'Not Recommended for New Designs' before integrating into any production roadmap. Ensure compatibility with existing inventory strategies given the obsolescence warning associated with this component family.
Selection Notes
Select this component only for maintenance or retrofit projects where the original design specifies the BCX71H series. Evaluate the -45V VCEO rating to ensure it meets circuit requirements. Consider the limited collector current of -0.2A when designing load paths. Verify that the SOT-23 footprint matches the target PCB layout constraints.
Part Context
The BCX71HT216 belongs to the BCX71H series of general-purpose transistors. These devices are widely used in consumer electronics and industrial control systems for low-power amplification. The SST3 package provides a small form factor suitable for space-constrained portable devices. The product line focuses on reliability and consistent hFE performance across operating temperatures.
Replacement Considerations
The BC847BT116 is listed as a similar level replacement with the same pinout and package. Note that the BC847B is an NPN transistor, whereas the BCX71H is PNP; verify polarity requirements carefully before substitution.
