Parameter Comparison

Engineering Selection Recommendations

Both the MMSZ4708-TP and MMSZ4708T1G are active products with identical zener voltage, tolerance, power rating, and reverse leakage specifications. Both components are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

The MMSZ4708T1G (onsemi) demonstrates a lower maximum forward voltage of 900 mV compared to 950 mV for the MMSZ4708-TP, representing improved forward conduction characteristics. Both parts operate across the identical temperature range of -55°C to 150°C and utilize the same SOD-123 surface mount package.

Selection between these parts is based on availability, supply chain requirements, and manufacturer preference, as electrical and mechanical specifications are equivalent for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Are the MMSZ4708-TP and MMSZ4708T1G electrically interchangeable?

A: Yes. Both parts share identical zener voltage (22 V), tolerance (±5%), power rating (500 mW), reverse leakage current (10 nA @ 16.7 V), and operating temperature range (-55°C to 150°C). The MMSZ4708T1G exhibits a lower forward voltage specification, which is a favorable characteristic for forward conduction applications.

Q: Can these parts be used interchangeably in existing circuit designs?

A: Yes. Both components are packaged in SOD-123 surface mount configuration with identical pinout and footprint requirements. No circuit board modifications are required for substitution.

Q: What is the significance of the forward voltage difference between these parts?

A: The MMSZ4708T1G forward voltage maximum of 900 mV is lower than the MMSZ4708-TP specification of 950 mV at 10 mA. This difference represents improved forward conduction efficiency in the onsemi part and does not affect zener regulation performance in voltage reference applications.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the MMSZ4708-TP and MMSZ4708T1G are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component use.

Q: What packaging format is used for these parts?

A: Both parts are supplied in Tape & Reel (TR) format in SOD-123 surface mount package configuration, suitable for automated assembly processes.
