PMD9050D,115

Overview

The PMD9050D is a MOSFET driver integrated circuit housed in an SC-74 (SOT457) plastic surface-mounted package. It combines an NPN transistor, a high-speed switching diode, and an NPN/PNP transistor pair configured as a silicon-controlled switch. Key electrical parameters include a collector-emitter voltage of 45 V, a peak collector current of 0.2 A, and a total power dissipation of 290 mW on FR4 PCBs. The device operates within an ambient temperature range of -65 °C to +150 °C.

Feature Summary

• Integrates a general-purpose transistor and high-speed switching diode for driver applications
• Includes a silicon-controlled switch to bypass the driver transistor
• Features application-optimized pinout with internal connections to minimize layout effort

Applications

• MOSFET driver circuits utilizing a silicon-controlled switch

Procurement Notes

Verify the manufacturer designation carefully, as the standard product business was transferred to Nexperia in February 2017. Confirm that the ordering suffix matches the required packing method, such as tape and reel configurations. Ensure the component source aligns with current corporate ownership records to guarantee authenticity and traceability during acquisition.

Selection Notes

Select this component when space-saving solutions and reduced component counts are prioritized. The internal connections minimize layout complexity compared to discrete implementations. Evaluate thermal resistance requirements against the specific PCB material, as power dissipation limits differ between FR4 and ceramic substrates.

Part Context

This device belongs to the MOSFET driver category, specifically designed to enhance switching performance through integrated control logic. It consolidates multiple discrete semiconductor functions into a single small outline package, facilitating compact design architectures in industrial and consumer electronics where efficient gate driving is critical.
