ZTX795A Equivalent & Substitute Parts

Part Overview

The ZTX795A is an active PNP bipolar junction transistor manufactured by Diodes Incorporated, designed for general-purpose switching and amplification applications. This device features a 140 V collector-emitter breakdown voltage rating, 500 mA maximum collector current, and 1 W power dissipation capability in a through-hole E-Line (TO-92 compatible) package. The ZTX795A is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to provide design flexibility when the primary part is unavailable or when application requirements necessitate alternative electrical or mechanical characteristics within acceptable parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZTX795A is determined by strict electrical and mechanical compatibility criteria. A valid substitute must satisfy the following conditions:

Mandatory Electrical Parameters:

• Transistor type must be PNP
• Collector-emitter breakdown voltage must equal or exceed 140 V
• Maximum collector current must equal or exceed 500 mA
• Maximum power dissipation must equal or exceed 1 W
• Transition frequency must equal or exceed 100 MHz

Mandatory Mechanical Parameters:

• Mounting type must be through-hole
• Package must be physically compatible with TO-92 or equivalent footprint

Compliance Requirements:

• RoHS3 compliance required
• REACH unaffected status required
• Active product status required

The 2N5401YBU meets all mandatory electrical parameters with higher ratings in voltage (150 V), current (600 mA), power (625 mW), and frequency (400 MHz) capabilities. Physical package compatibility is confirmed through TO-92-3 designation. Full compliance certifications are maintained.

Engineering Selection Recommendations

The 2N5401YBU is a qualified substitute for the ZTX795A based on the following engineering criteria:

Electrical Compatibility: The 2N5401YBU exceeds all minimum electrical requirements of the ZTX795A. Breakdown voltage is 10 V higher (150 V vs. 140 V), collector current capacity is 100 mA higher (600 mA vs. 500 mA), and transition frequency is 300 MHz higher (400 MHz vs. 100 MHz). These higher ratings provide operational margin in applications where the ZTX795A is specified.

Mechanical Compatibility: Both devices utilize through-hole mounting in physically compatible TO-92 packages. The 2N5401YBU is designated TO-92-3 (TO-226AA), which is mechanically interchangeable with the ZTX795A E-Line-3 package on standard PCB footprints.

Compliance Status: Both devices maintain active product status, ROHS3 compliance, and REACH unaffected classification, satisfying regulatory requirements for equivalent component selection.

Operating Temperature Consideration: The ZTX795A supports operation to 200°C junction temperature, while the 2N5401YBU is rated to 150°C. Applications requiring operation above 150°C require verification that the 2N5401YBU maximum temperature rating is not exceeded.

Frequently Asked Questions (FAQ)

Q: Can the 2N5401YBU be used as a direct replacement for the ZTX795A in all applications?

A: The 2N5401YBU meets or exceeds all mandatory electrical and mechanical parameters required for substitution. However, applications operating above 150°C junction temperature must account for the lower maximum temperature rating of the 2N5401YBU (150°C vs. 200°C for the ZTX795A).

Q: Are the packages physically identical?

A: Both devices use through-hole TO-92 style packages. The ZTX795A is designated E-Line-3 (TO-92 compatible) and the 2N5401YBU is designated TO-92-3 (TO-226AA). These packages are mechanically interchangeable on standard PCB footprints designed for TO-92 components.

Q: What are the key electrical differences between these parts?

A: The 2N5401YBU provides higher voltage rating (150 V vs. 140 V), higher current capacity (600 mA vs. 500 mA), and significantly higher transition frequency (400 MHz vs. 100 MHz). The ZTX795A exhibits higher DC current gain (300 vs. 60 at specified test conditions) and lower saturation voltage (250 mV vs. 500 mV at specified test conditions).

Q: Are both parts RoHS compliant?

A: Yes. Both the ZTX795A and 2N5401YBU are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the significance of the higher transition frequency in the 2N5401YBU?

A: The 2N5401YBU transition frequency of 400 MHz exceeds the ZTX795A specification of 100 MHz. This parameter indicates the frequency at which current gain begins to decrease. The higher frequency capability of the 2N5401YBU provides margin for high-frequency switching applications and does not restrict its use in lower-frequency applications.

Q: Can the 2N5401YBU be used in high-temperature applications above 150°C?

A: The 2N5401YBU maximum junction temperature rating is 150°C. Applications requiring sustained operation above 150°C must use the ZTX795A, which is rated to 200°C junction temperature.
