Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZT52C36-7-F-79 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Zener voltage rating: 36 V nominal
• Impedance (Max): 90 Ohms
• Reverse leakage current: 100 nA @ 25.2 V
• Forward voltage: 900 mV @ 10 mA
• Operating temperature range: -65°C ~ 150°C

Mechanical Compatibility Requirements:

• Package type: SOD-123 surface mount
• Mounting type: Surface mount

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status

Substitute parts must match all electrical parameters and maintain the same package footprint. Power rating may exceed the original specification without compromising circuit function, provided all other parameters remain within tolerance.

Parameter Comparison

Engineering Selection Recommendations

The BZT52C36-7-F is the direct active equivalent for the obsolete BZT52C36-7-F-79. Both parts are manufactured by Diodes Incorporated and share identical electrical characteristics across all critical parameters: 36 V zener voltage, 90 Ohms maximum impedance, 100 nA reverse leakage, and 900 mV forward voltage specification.

The substitute part BZT52C36-7-F provides increased power dissipation capability (500 mW versus 370 mW), which represents an enhancement without introducing compatibility issues. The tolerance specification widens slightly from ±5.56% to ±6%, remaining within acceptable engineering margins for voltage regulation applications.

Both parts maintain identical operating temperature range (-65°C ~ 150°C), package footprint (SOD-123), and compliance certifications (RoHS3, REACH unaffected). The substitute part is currently in active production status with substantial inventory availability, ensuring long-term procurement viability.

Frequently Asked Questions (FAQ)

Q: Can BZT52C36-7-F replace BZT52C36-7-F-79 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters. The substitute part features higher power dissipation (500 mW versus 370 mW), which does not compromise circuit function. The SOD-123 package footprint is identical, requiring no PCB layout modifications.

Q: What is the difference in power rating between these parts?

A: The BZT52C36-7-F-79 is rated at 370 mW maximum power dissipation, while the BZT52C36-7-F is rated at 500 mW. The higher rating on the substitute part provides additional thermal margin and does not affect electrical performance in applications designed for the original part.

Q: Are there packaging differences between these parts?

A: Both parts use the SOD-123 surface mount package. The main part number BZT52C36-7-F-79 does not specify packaging format in the available data, while BZT52C36-7-F is supplied in Tape & Reel (TR) format. The physical package dimensions and PCB footprint remain identical.

Q: Is the tolerance specification difference significant?

A: The tolerance widens from ±5.56% to ±6% on the substitute part. For a 36 V zener diode, this represents a variation of approximately 0.16 V, which is negligible in typical voltage regulation and transient protection applications.

Q: Why is the original part marked as obsolete?

A: The BZT52C36-7-F-79 is classified as obsolete, indicating discontinued production. The BZT52C36-7-F serves as the active production equivalent and is recommended for all new designs and ongoing procurement requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the BZT52C36-7-F-79 and BZT52C36-7-F are RoHS3 compliant with REACH unaffected status, meeting current environmental and regulatory requirements.
