NHUMH9F

Overview

The NHUMH9F is an NPN/NPN Resistor-Equipped double Transistor (RET) from Nexperia, housed in a SOT363 (SC-88/TSSOP6) surface-mount package. It integrates two isolated NPN transistors with built-in bias resistors: R1 = 10 kΩ and R2 = 47 kΩ. Key electrical parameters include a collector-emitter breakdown voltage (VCEO) of 80 V, a maximum output current (IO) of 100 mA per transistor, and a transition frequency (fT) of 170 MHz at IC = 10 mA. The device features a DC current gain (hFE) of at least 100 at IC = 10 mA and VCE = 5 V. Total power dissipation is rated at 350 mW per device at Tamb ≤ 25 °C.

Feature Summary

• Integrates dual NPN transistors with fixed internal bias resistors to reduce external component count.
• Provides high breakdown voltage capability suitable for digital switching applications.
• Offers simplified circuit design through pre-biased configuration, reducing pick-and-place costs.

Applications

• Digital logic circuits
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific suffix 'F' against the official datasheet revision history. The provided document indicates that the NHUMH9 series has been updated to non-automotive qualification status in recent revisions. Confirm whether the 'F' variant retains any specific automotive or reliability certifications distinct from the standard production data sheet specifications before finalizing procurement.

Selection Notes

Select the NHUMH9F when a compact dual NPN solution with integrated base and emitter resistors is required. The 10 kΩ input resistor value distinguishes it from the NHUMH10 (2.2 kΩ) and NHUMH13 (4.7 kΩ) variants within the same family. Ensure the application operates within the 80 V collector-emitter voltage limit and 100 mA current rating constraints defined in the limiting values section.

Part Context

The NHUMH9F belongs to the NHUMH10/13/9 series of NPN/NPN resistor-equipped double transistors manufactured by Nexperia USA Inc. These devices are designed as cost-saving alternatives to standard discrete double transistors like the BC846 series in digital applications. The part utilizes the SOT363 plastic surface-mounted package, providing a small footprint for space-constrained designs.

Replacement Considerations

Direct pin-compatible replacements within the same series include NHUMH10 and NHUMH13, though their internal resistor values differ significantly. For general-purpose NPN double transistors without integrated resistors, the BC846 series may serve as a functional alternative if external biasing components can be added to the design.
