Overview
The PN5432 is an N-channel switch manufactured by onsemi, designed for analog or digital switching applications requiring very low on-resistance. It operates within a drain-gate voltage of 25 V and a gate-source voltage range of -25 V to +25 V. The device features a maximum total device dissipation of 350 mW at 25°C ambient temperature. Electrical characteristics include a zero-gate voltage drain current (IDSS) of up to 150 mA and a drain-source on-voltage (VDS(on)) of 50 mV at 10 mA. The package type is TO-92.
Feature Summary
- Designed for applications where very low on-resistance is mandatory
- Suitable for both analog and digital switching applications
- Operates with high input impedance due to MOSFET structure
Applications
- Analog signal routing
- Digital logic level shifting
- Battery protection circuits
Procurement Notes
Verify the manufacturer origin as Fairchild Semiconductor products are now part of onsemi. Confirm the specific package variant (TO-92) matches your PCB footprint requirements. Check for any obsolescence notices or lifecycle status changes from the original manufacturer documentation before finalizing procurement plans.
Selection Notes
Select this component when low on-resistance is critical for minimizing signal loss in switching paths. Ensure the operating voltage does not exceed the 25 V limits for Drain-Gate or Gate-Source voltages. Consider the thermal resistance values if multiple devices are placed closely together on the board.
Part Context
This component belongs to a family of N-channel switches that includes variants like PN5433 and PN5434. These devices share similar packaging and basic operational principles but differ in specific electrical parameters such as leakage current and on-resistance thresholds to suit different circuit sensitivities.
Replacement Considerations
PN5433 and PN5434 are direct functional substitutes within the same series. Verify pinout compatibility and ensure the replacement's specific electrical ratings meet the design requirements.
