Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N4747A_S00Z is determined by strict equivalence across the following critical parameters:

• Zener Voltage (Vz): 20 V nominal
• Power Rating: 1 W maximum
• Voltage Tolerance: ±5%
• Impedance (Zzt): 22 Ohms maximum
• Reverse Leakage Current: 5 µA @ 15.2 V
• Operating Temperature Range: -65°C ~ 200°C
• Package Type: DO-41 through-hole axial configuration

Substitute parts must match all electrical specifications and maintain the same physical package format to ensure direct replacement without circuit board redesign or mechanical modification.

Parameter Comparison

Engineering Selection Recommendations

The 1N4747A manufactured by Lumimax Optoelectronic Technology is a direct electrical and mechanical equivalent to the obsolete 1N4747A_S00Z. Both components share identical zener voltage, power rating, impedance, reverse leakage current, and operating temperature specifications. The Lumimax part is currently in active production status with substantial inventory availability (15,200 pcs), whereas the onsemi original is obsolete.

Both parts maintain REACH Unaffected and EAR99 export classification status. The Lumimax substitute carries RoHS Compliance certification, providing additional regulatory alignment for modern manufacturing environments. The DO-41G package designation for the Lumimax part represents a standard variant of the DO-41 through-hole axial package and is mechanically and electrically compatible with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the Lumimax 1N4747A directly replace the onsemi 1N4747A_S00Z without circuit modification?

A: Yes. Both components meet identical electrical specifications for zener voltage (20 V), power rating (1 W), impedance (22 Ohms maximum), reverse leakage current (5 µA @ 15.2 V), and operating temperature range (-65°C ~ 200°C). The DO-41 through-hole axial package is mechanically identical, allowing direct pin-for-pin substitution.

Q: What is the difference between DO-41 and DO-41G package designations?

A: Both designations refer to the same DO-41 through-hole axial package format. The "G" suffix in DO-41G is a supplier-specific variant identifier and does not indicate a functional or dimensional difference. The packages are mechanically and electrically interchangeable.

Q: Are there any compliance or certification differences between the original and substitute?

A: Both parts maintain REACH Unaffected and EAR99 export classification status. The Lumimax substitute includes RoHS Compliance certification, which the onsemi original does not specify. This additional certification supports compliance with modern environmental and manufacturing standards.

Q: Why is the onsemi 1N4747A_S00Z listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Lumimax equivalent remains in active production with current inventory availability, making it the appropriate selection for new designs and component replenishment.

Q: Are the reverse leakage current specifications identical?

A: Yes. Both the original and substitute specify 5 µA maximum reverse leakage current measured at 15.2 V, ensuring equivalent performance in voltage regulation and protection circuit applications.
