Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZTX792ASTOB is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitution:

Electrical Parameters (Must Match):

• Transistor Type: PNP
• Current - Collector (Ic) (Max): 2 A
• Voltage - Collector Emitter Breakdown (Max): 70 V
• Vce Saturation (Max) @ Ib, Ic: 500mV @ 200mA, 2A
• Current - Collector Cutoff (Max): 100nA (ICBO)
• DC Current Gain (hFE) (Min) @ Ic, Vce: 300 @ 10mA, 2V
• Power - Max: 1 W
• Frequency - Transition: 100MHz
• Operating Temperature: -55°C ~ 200°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: E-Line-3, Formed Leads
• Supplier Device Package: E-Line (TO-92 compatible)

The ZTX792ASTZ meets all electrical and mechanical parameter requirements for direct substitution. The primary difference is packaging format (Cut Tape versus standard packaging) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The ZTX792ASTZ is a direct electrical and mechanical equivalent to the ZTX792ASTOB. Both components are manufactured by Diodes Incorporated and share identical electrical specifications across all critical parameters including collector current, breakdown voltage, saturation characteristics, current gain, power rating, and frequency response.

The ZTX792ASTZ maintains full compliance with RoHS3 and REACH requirements, identical to the main part. Both components carry the same ECCN and HTSUS classifications.

The primary distinction is product status: the ZTX792ASTOB is classified as obsolete, while the ZTX792ASTZ is active. The ZTX792ASTZ is supplied in Cut Tape (CT) packaging format, whereas the main part uses standard packaging. Both employ identical E-Line (TO-92 compatible) through-hole mounting configuration with formed leads.

For applications requiring the ZTX792ASTOB, the ZTX792ASTZ provides full functional and mechanical compatibility with no electrical performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the ZTX792ASTZ directly replace the ZTX792ASTOB in existing designs?

A: Yes. The ZTX792ASTZ meets all electrical and mechanical specifications of the ZTX792ASTOB. Both components are PNP transistors with identical ratings for collector current (2 A), breakdown voltage (70 V), saturation voltage, current gain, power dissipation, and frequency response. Both use E-Line (TO-92 compatible) through-hole mounting with formed leads.

Q: What is the difference between the ZTX792ASTOB and ZTX792ASTZ?

A: The components are electrically identical. The ZTX792ASTOB is classified as obsolete, while the ZTX792ASTZ is active. The ZTX792ASTZ is supplied in Cut Tape (CT) packaging format. Both share the same base product number designation and manufacturer.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the ZTX792ASTOB and ZTX792ASTZ carry identical compliance certifications: RoHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). Both share the same ECCN (EAR99) and HTSUS (8541.29.0075) classifications.

Q: Does the Cut Tape packaging of the ZTX792ASTZ affect circuit performance?
