PUMH7,115

Overview

The PUMH7,115 is a dual NPN pre-biased transistor array manufactured by Nexperia USA Inc. It integrates two independent NPN transistors with built-in bias resistors into a single surface-mount package. The device features a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (Ic) of 100 mA. Each transistor includes a base resistor (R1) of 4.7 kΩ. The component is housed in a 6-TSSOP (SC-88/SOT-363) package with dimensions of 2.2 x 1.35 x 1.1 mm. It supports a maximum power dissipation of 300 mW and operates within a temperature range up to +150 °C. The unit meets AEC-Q100 automotive qualification standards.

Feature Summary

• Integrates two NPN transistors with fixed internal bias resistors to reduce external component count and PCB space.
• Provides consistent DC current gain characteristics due to matched integrated resistors.
• Qualified for automotive applications under AEC-Q100 standards for reliability.

Applications

• General-purpose switching circuits requiring compact layout solutions.
• Automotive electronic systems demanding AEC-Q100 qualified components.
• Driver circuits for low-power loads such as LEDs or relays.

Procurement Notes

Verify the complete part number including the suffix ',115' to ensure correct tape-and-reel packaging configuration. Confirm that the 6-TSSOP footprint matches the target PCB design. Check for RoHS3 compliance status if required by specific environmental regulations. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines to prevent package damage during soldering.

Selection Notes

Select this component when a dual NPN switch with fixed bias is required in a minimal footprint. Compare the 4.7 kΩ base resistance against circuit drive requirements to ensure adequate saturation. Consider the 300 mW power dissipation limit relative to ambient temperature derating curves. Verify that the 50 V voltage rating exceeds the maximum expected load voltage with appropriate safety margins.

Part Context

The PUMH7,115 belongs to the PUMH series of pre-biased resistors (PBRs) from Nexperia. These devices combine bipolar junction transistors with internal resistors to simplify driver circuit designs. The '115' suffix denotes the specific reel packaging format. This series is designed to replace discrete transistor and resistor combinations, offering improved consistency and reduced assembly complexity in high-volume manufacturing environments.

Replacement Considerations

Direct substitutes include other Nexperia PUMH series variants with different resistor values, such as PUMH9,115 (10 kΩ base resistor). Cross-manufacturer equivalents should match the 6-TSSOP package, 50 V rating, and 100 mA current capability. Verify pinout compatibility before substitution to avoid circuit malfunction.
