Engineering Selection Recommendations

BZD27C120P-E3-08 Selection: This substitute part maintains full electrical equivalence with the BZD17C120P RVG across all critical parameters. The impedance specification of 250 Ohms is superior to the primary part's 300 Ohms maximum, providing improved performance characteristics. The extended operating temperature range of -65°C to 175°C provides additional thermal margin. Both parts carry ROHS3 compliance and unlimited moisture sensitivity rating. This part is suitable for general industrial applications requiring 120 V Zener functionality.

BZD27C120P-HE3-08 Selection: This substitute part is qualified to automotive standards with AEC-Q101 certification, in addition to maintaining full electrical equivalence with the BZD17C120P RVG. The impedance specification of 250 Ohms and extended operating temperature range of -65°C to 175°C match the BZD27C120P-E3-08. This part is designated for automotive-grade applications where AEC-Q101 qualification is required or specified.

Both substitute parts are active products with established supply availability and full compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can BZD27C120P-E3-08 or BZD27C120P-HE3-08 be used as direct replacements for BZD17C120P RVG?

A: Yes. Both substitute parts maintain equivalent electrical performance at the critical parameters: 120 V nominal Zener voltage, 800 mW maximum power dissipation, 1 µA reverse leakage current, and 1.2 V forward voltage. Package compatibility is confirmed through identical DO-219AB form factor and surface mount mounting type.

Q: What is the difference between BZD27C120P-E3-08 and BZD27C120P-HE3-08?

A: The primary difference is qualification level. BZD27C120P-HE3-08 carries AEC-Q101 automotive qualification, while BZD27C120P-E3-08 is standard grade. Both parts are electrically and mechanically identical. Selection depends on application requirements and automotive compliance specifications.

Q: Are there any impedance differences between the main part and substitutes?

A: The BZD17C120P RVG specifies a maximum impedance of 300 Ohms, while both substitute parts specify 250 Ohms maximum. The lower impedance of the substitute parts represents improved performance and does not create compatibility issues in circuit applications.

Q: What is the operating temperature difference?

A: The BZD17C120P RVG operates from -55°C to 175°C. Both substitute parts extend the lower temperature limit to -65°C, providing an additional 10°C of cold-temperature operation. The upper temperature limit of 175°C remains identical.

Q: Are all three parts ROHS3 compliant?

A: Yes. The BZD17C120P RVG, BZD27C120P-E3-08, and BZD27C120P-HE3-08 are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Which substitute part should be selected for automotive applications?

A: BZD27C120P-HE3-08 is specified for automotive applications with AEC-Q101 qualification. BZD27C120P-E3-08 is suitable for general industrial applications without automotive qualification requirements.

Q: Is the DO-219AB package identical across all three parts?

A: Yes. All three parts use the DO-219AB package form factor (Sub SMA / SMF designation), ensuring mechanical and footprint compatibility on printed circuit boards.
