CMPFJ310 BK

Overview

The CMPFJ310 BK is a P-Channel Junction Field Effect Transistor (JFET) manufactured by Central Semiconductor Corp. It is designed for high-voltage applications and features a maximum drain-source voltage of 60V and a continuous drain current of 25mA. The device exhibits a low on-resistance of 4kΩ at zero gate bias and a typical pinch-off voltage range from -0.8V to -4V. Packaged in a DO-35 glass axial leaded format, it supports a junction temperature up to 200°C and operates within an ambient temperature range of -65°C to 175°C.

Feature Summary

• Utilizes a P-Channel JFET configuration suitable for high-voltage switching and amplification tasks.
• Features a robust DO-35 glass axial package capable of withstanding high junction temperatures up to 200°C.
• Designed for low-power signal processing with defined pinch-off voltage characteristics.

Applications

• High-voltage analog signal switching circuits
• Constant current source implementations
• Low-noise pre-amplifier stages

Procurement Notes

Verify the specific suffix 'BK' against the manufacturer's official documentation to confirm packaging or tape-and-reel specifications. Confirm RoHS compliance status directly with Central Semiconductor Corp as historical data may vary. Ensure the DO-35 axial lead form factor matches the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a P-Channel JFET with a 60V breakdown voltage and 25mA current rating is required. The DO-35 package is appropriate for through-hole mounting where space allows. Compare the -0.8V to -4V pinch-off voltage range against circuit design needs to ensure proper biasing conditions are met for the intended application.

Part Context

This part belongs to the Central Semiconductor JFET family, specifically utilizing the CP310 die structure often associated with high-voltage NPN/PNP equivalents but configured here as a P-Channel device. It shares the DO-35 axial leaded package commonality with other small-signal discrete semiconductors from the manufacturer, facilitating compatibility with standard through-hole assembly processes.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided reference material. Engineers should evaluate generic P-Channel JFETs with matching V(BR)DSS, ID, and RDS(on) parameters. Verify that any alternative device maintains the DO-35 package outline and thermal characteristics to ensure mechanical fit and reliability.
