Frequently Asked Questions (FAQ)

Q: Can the PUMH7H-QF replace the PUMH7HF in existing designs?

A: Yes. The PUMH7H-QF is electrically and mechanically equivalent to the PUMH7HF. All electrical parameters, including collector current, breakdown voltage, base resistor value, current gain, saturation voltage, transition frequency, and power dissipation, are identical. Both components use the 6-TSSOP surface mount package. Direct substitution is supported without circuit redesign.

Q: What is the difference between the PUMH7HF and PUMH7H-QF?

A: The primary differences are product status and qualification level. The PUMH7HF is obsolete, while the PUMH7H-QF is active. The PUMH7H-QF carries automotive-grade designation and AEC-Q101 qualification, making it suitable for automotive applications. The PUMH7H-QF is supplied in Tape & Reel packaging, whereas the PUMH7HF packaging format is not specified in the provided data.

Q: Are there any electrical performance differences between these parts?

A: No. Both the PUMH7HF and PUMH7H-QF share identical electrical specifications: 100mA maximum collector current, 50V collector-emitter breakdown voltage, 4.7kOhms base resistor, 200 minimum DC current gain, 100mV maximum saturation voltage, 230MHz transition frequency, and 240mW maximum power dissipation.

Q: What does "pre-biased" mean in the context of these transistors?

A: Pre-biased refers to the integrated internal base resistor (4.7kOhms in this case). This resistor is connected between the base and emitter internally, allowing the transistor to operate with simplified external circuitry. The pre-biased configuration reduces the component count required for switching applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the PUMH7HF and PUMH7H-QF are ROHS3 compliant. The PUMH7H-QF additionally carries REACH Unaffected status.

Q: What is the significance of the 6-TSSOP package designation?

A: The 6-TSSOP (Thin Shrink Small Outline Package) is a surface mount package containing six leads. This package is also designated as SC-88 or SOT-363. Both the PUMH7HF and PUMH7H-QF use this identical package, ensuring mechanical compatibility in PCB layouts and assembly processes.

Q: Why is the PUMH7HF listed as obsolete?

A: The PUMH7HF has reached end-of-life status. The PUMH7H-QF serves as the active replacement, offering the same electrical and mechanical specifications with the added benefit of ongoing manufacturer support and supply availability.

Q: Can the PUMH7H-QF be used in non-automotive applications?

A: Yes. The PUMH7H-QF is suitable for any application requiring the specified electrical and mechanical parameters. The automotive-grade qualification and AEC-Q101 certification indicate enhanced reliability but do not restrict use to automotive applications.
