PRMH10Z

Overview

The PRMH10 is a dual NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in an ultra-small DFN1412-6 (SOT1268) leadless surface-mount package. It integrates two NPN transistors with built-in bias resistors to simplify circuit design and reduce component count. The device supports a collector-emitter voltage of 50 V and an output current of 100 mA per transistor. Key electrical parameters include a DC current gain (hFE) of at least 100 at IC = 10 mA, a transition frequency (fT) of 230 MHz, and a total power dissipation of 480 mW for the device. The package height is 0.5 mm, and it is qualified under AEC-Q101 standards.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistors to minimize external components
• Ultra-thin DFN1412-6 package with a low profile of 0.5 mm for space-constrained designs
• AEC-Q101 qualified for automotive reliability requirements
• High switching performance with a transition frequency of 230 MHz

Applications

• Digital logic applications requiring compact dual-transistor solutions
• Cost-effective replacement for discrete BC847/BC857 series in digital circuits
• Input buffering and control for integrated circuits
• Load switching functions in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official catalog to ensure correct packaging and tape-and-reel specifications. Confirm that the DFN1412-6 footprint matches your PCB layout guidelines. Check the latest product data sheet for any updates to marking codes or thermal derating curves before finalizing procurement orders.

Selection Notes

Select the PRMH10 when a dual NPN configuration with fixed biasing is required in a minimal footprint. Ensure the application voltage does not exceed the 50 V collector-emitter rating. Consider the 480 mW total power dissipation limit and verify thermal management on the FR4 PCB if operating near maximum ratings. The AEC-Q101 qualification makes it suitable for automotive-grade designs.

Part Context

The PRMH10 belongs to Nexperia's RET family of resistor-equipped double transistors. It serves as the NPN/NPN complement to the PRMD10 (NPN/PNP). Both devices share the same DFN1412-6 package and are designed to replace multiple discrete components in digital switching and logic interface applications, offering reduced assembly costs and board space.

Replacement Considerations

The PRMD10 is the complementary NPN/PNP variant within the same package. For single-transistor replacements, discrete BC847 types may be used but will require additional external bias resistors and occupy more board area. No direct pin-compatible substitutes with identical internal resistor values are listed in the public datasheet.
