APL502B2G

Single FETs, MOSFETs Overview

The APL502B2G is a single N-channel Power MOSFET manufactured by Microchip Technology, designed for high-voltage power switching applications. It features a T-MAX™ [B2] through-hole package, specifically a TO-247-3 variant, which facilitates robust thermal management and mechanical mounting. The device supports a maximum drain-source voltage (Vdss) of 500 V and delivers a continuous drain current (Id) of 58 A at case temperature. Key electrical characteristics include a maximum gate-source voltage (Vgs) of ±30 V and a threshold voltage (Vgs(th)) of 4 V at 2.5 mA. At 12 V gate drive and 29 A drain current, the on-resistance (Rds(on)) is maximized at 90 mΩ. The component handles a maximum power dissipation of 730 W at case temperature and operates within a junction temperature range of -55°C to 150°C.

Single FETs, MOSFETs Procurement Notes

Verify the specific suffix B2 corresponds to the T-MAX™ [B2] package configuration when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure ordering quantities align with standard tube packaging requirements. Cross-reference the datasheet revision date to validate parameter accuracy against current production batches.

Single FETs, MOSFETs Selection Notes

Select this component for applications requiring high voltage isolation and significant current handling in a through-hole format. Compare Rds(on) specifications against system efficiency targets at the intended operating gate voltage. Evaluate thermal resistance parameters to ensure adequate heat sinking solutions are available for the 730 W dissipation rating under worst-case ambient conditions.

Single FETs, MOSFETs Part Context

This part belongs to the APL502 series of linear power MOSFETs from Microchip Technology. The series is characterized by high voltage ratings and rugged construction suitable for demanding power electronics. The B2 suffix denotes the specific T-MAX™ package variant, distinguishing it from other package options like ISOTOP or standard TO-247 configurations within the broader product family.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes may include other 500 V, 58 A N-channel MOSFETs in TO-247-3 packages from Microchip or other manufacturers, provided pinouts and thermal characteristics match. Verify that replacement devices meet or exceed the 90 mΩ Rds(on) and 730 W power dissipation requirements.
