PUMH7F

Overview

The PUMH7F is a dual NPN resistor-equipped transistor manufactured by Nexperia USA Inc. in the SOT363 (SC-88) surface-mount package. It integrates two NPN transistors with built-in bias resistors, where R1 is fixed at 4.7 kΩ and R2 remains open. The device supports a maximum collector-emitter voltage of 50 V and a continuous output current of 100 mA per transistor. Total power dissipation is rated at 300 mW for the dual device configuration. Key electrical characteristics include a DC current gain (hFE) minimum of 200 at 1 mA collector current and a collector-emitter saturation voltage of 100 mV maximum at 5 mA.

Feature Summary

• Built-in bias resistors simplify circuit design and reduce component count
• Dual NPN configuration allows control of IC inputs and peripheral drivers
• SOT363 package facilitates reduced pick-and-place costs

Applications

• Low current peripheral driver
• Replacement of general purpose transistors in digital applications
• Control of IC inputs

Procurement Notes

Verify the specific ordering suffix to confirm the exact tape and reel or cut tape packaging format required for your assembly line. Confirm that the SOT363 footprint matches your PCB layout guidelines before finalizing procurement. Ensure compliance with RoHS directives as specified in the product data sheet.

Selection Notes

Select the PUMH7F when a compact dual NPN solution with integrated base biasing is required. The 4.7 kΩ internal resistor value is suitable for standard logic interface applications. Consider the 50 V breakdown voltage and 100 mA current limits to ensure adequate headroom for the target switching application.

Part Context

The PUMH7 belongs to the PEMH7/PUMH7 family of NPN/NPN resistor-equipped transistors. While the PEMH7 variant utilizes the SOT666 package, the PUMH7 specifically uses the SOT363 (SC-88) plastic surface-mounted package. Both variants share identical electrical characteristics but differ in physical dimensions and pinning configurations.
