Overview
The onsemi PN5432_D27Z is an N-Channel Switch designed for analog or digital switching applications requiring very low On Resistance. It utilizes Process 58 technology and is housed in a TO-92 package with the D27Z tape and reel ordering suffix. The device features a Drain-Gate Voltage of 25 V, a Gate-Source Voltage of -25 V, and operates within a junction temperature range of -55 to +150 °C. Total device dissipation is rated at 350 mW, derating by 2.8 mW/°C above 25°C.
Feature Summary
- Designed for analog or digital switching applications where very low On Resistance is mandatory
- Utilizes Process 58 technology for optimized performance characteristics
- Housed in a standard TO-92 plastic package suitable for through-hole mounting
Applications
- Analog signal switching
- Digital logic level switching
- Low resistance circuit protection
Procurement Notes
Verify the specific D27Z suffix corresponds to the required Tape and Reel packaging configuration before procurement. Confirm that the TO-92 form factor aligns with the target PCB footprint. Ensure the sourcing channel provides documentation confirming the component originates from Fairchild Semiconductor or its successor entities, as onsemi acquired these assets. Cross-reference the datasheet revision against the manufacturing date code to ensure specification consistency.
Selection Notes
Select this component when a low-cost N-Channel switch with minimal on-resistance is required for general-purpose applications. The TO-92 package limits power dissipation capabilities compared to surface-mount alternatives, making it suitable for lower current scenarios. Evaluate the gate-source cutoff voltage requirements against the driving circuit's output levels to ensure reliable switching thresholds are met during operation.
Part Context
This part belongs to the PN5432/PN5433/PN5434 family of N-Channel Switches originally developed by Fairchild Semiconductor. These devices were engineered to provide robust switching performance in compact packages. The PN5432 variant specifically targets applications demanding the lowest on-resistance within the series, distinguishing it from the PN5433 and PN5434 models which offer higher resistance values.
Replacement Considerations
Direct substitutes include the PN5433 and PN5434 variants from the same family, though their on-resistance specifications differ. Verify pinout compatibility and thermal characteristics when considering alternative manufacturers' N-Channel switches in the TO-92 package.
