Engineering Selection Recommendations

All three parts—1N5367B-TP, 1N5367BG, and 1N5367BRLG—are active-status components with ROHS3 compliance and REACH unaffected status, qualifying them for equivalent use in applications requiring 43 V, 5 W zener diodes.

1N5367B-TP (Micro Commercial Co): Primary part with DO-15 axial packaging and operating temperature range of -55°C ~ 150°C. Suitable for standard industrial and commercial applications within the specified temperature limits.

1N5367BG (onsemi): Substitute part with extended operating temperature range (-65°C ~ 200°C) and bulk packaging. Electrical specifications are identical to the main part. Bulk packaging format requires consideration for automated assembly processes.

1N5367BRLG (onsemi): Substitute part with extended operating temperature range (-65°C ~ 200°C) and cut tape packaging. Electrical specifications are identical to the main part. Cut tape format aligns with standard component tape-and-reel handling.

Selection between these parts depends on procurement requirements, packaging preferences, and application temperature operating conditions. All parts maintain identical electrical performance within the specified zener voltage, power dissipation, and impedance parameters.

Frequently Asked Questions (FAQ)

Q: Can 1N5367BG and 1N5367BRLG be used interchangeably with 1N5367B-TP?

A: Yes. All three parts share identical electrical specifications: 43 V zener voltage, ±5% tolerance, 5 W maximum power, 20 Ohms maximum impedance, and 500 nA reverse leakage current at 32.7 V. They are all through-hole axial components with active product status and ROHS3 compliance.

Q: What is the difference between 1N5367BG and 1N5367BRLG?

A: The primary difference is packaging format. 1N5367BG is supplied in bulk packaging, while 1N5367BRLG is supplied in cut tape (CT) packaging. Both are manufactured by onsemi and have identical electrical specifications and extended operating temperature range (-65°C ~ 200°C).

Q: Does the extended temperature range of the onsemi substitutes affect circuit performance?

A: The extended operating temperature range (-65°C ~ 200°C for onsemi parts versus -55°C ~ 150°C for the main part) does not alter electrical performance within the specified operating conditions. The extended range provides additional margin for applications operating at temperature extremes.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: All three parts are through-hole axial components. The main part uses DO-204AC/DO-15 packaging, while the onsemi substitutes use T-18 axial packaging. Both package types are standard axial through-hole formats with compatible lead spacing and mounting characteristics for PCB applications.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component use in regulated markets.
