PUMD6HX

Overview

The PUMD6HX is a dual pre-biased NPN transistor array manufactured by Nexperia USA Inc. It integrates one NPN transistor with an internal base resistor (R1) of 4.7 kΩ and an emitter resistor (R2) of 47 kΩ. The device features a maximum collector-emitter voltage (Vceo) of 50 V and a continuous collector current (Ic) of 100 mA. It operates within a temperature range of -55°C to +150°C and has a maximum power dissipation of 200 mW. The component is housed in a compact SOT-363 (SC-88) surface-mount package, designed for efficient space utilization in electronic circuits.

Feature Summary

• Integrates NPN transistor with built-in base and emitter resistors to reduce external component count
• Optimized low saturation voltage characteristics for improved switching efficiency
• Compact leadless surface-mount packaging suitable for high-density board layouts

Applications

• General-purpose switching applications
• Driver circuits for logic interfaces
• Level shifting and signal buffering

Procurement Notes

Verify the specific suffix '125' or similar against the manufacturer's official datasheet to confirm tape-and-reel quantities and packaging variants. Ensure the ordering part number matches the required resistance values and package type before finalizing procurement orders to avoid compatibility issues.

Selection Notes

Select this component when a single NPN pre-biased transistor with specific 4.7 kΩ base and 47 kΩ emitter resistors is required. Compare electrical parameters such as hFE and Vce(sat) against alternative arrays like PUMD10 if different resistance ratios are needed. Confirm that the SOT-363 footprint aligns with the target PCB design constraints.

Part Context

This part belongs to the PUMD series of pre-biased transistors from Nexperia. These devices combine bipolar junction transistors with integrated resistors to simplify circuit design. The PUMD6HX specifically provides an NPN configuration, distinguishing it from PNP-only or complementary PNP/NPN pairs found in other series members.

Replacement Considerations

Potential substitutes include the PUMD10 or PUMD13 from the same manufacturer family. Verify that the replacement part offers identical resistance values (4.7 kΩ / 47 kΩ) and compatible pinout configurations to ensure direct interchangeability without PCB redesign.
