2M17Z Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M17Z is an active-status Zener diode manufactured by Taiwan Semiconductor Corporation, rated for 17 V nominal Zener voltage with 2 W maximum power dissipation. This component is packaged in DO-204AC (DO-15) axial through-hole configuration and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, end-of-life considerations, or application-specific packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M17Z is permissible when the following electrical and mechanical criteria are satisfied:

Critical Matching Parameters:

• Voltage - Zener (Nominal): 17 V
• Tolerance: ±5%
• Mounting Type: Through Hole
• Package / Case: DO-204AC or DO-15 (Axial)
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Power - Maximum: Equal to or greater than 2 W
• Impedance (Maximum): Equal to or less than 9 Ohms
• Current - Reverse Leakage @ Vr: Equal to or less than 500 nA
• Operating Temperature Range: Must encompass or equal the specified range

The 1N5354B-TP meets all critical matching parameters and provides enhanced electrical performance characteristics, including higher maximum power dissipation (5 W) and lower impedance (2.5 Ohms), making it a direct functional substitute for the 2M17Z in applications where these improved specifications are compatible with circuit design requirements.

Engineering Selection Recommendations

2M17Z Selection Criteria: The 2M17Z is appropriate for applications requiring a 17 V Zener diode with 2 W power dissipation in DO-15 axial through-hole configuration. This part is active-status and maintains full RoHS3 compliance. The operating temperature range extends to 175°C, supporting high-temperature circuit environments. Selection of the 2M17Z is indicated when the specified 2 W power rating and 9 Ohms maximum impedance are design requirements.

1N5354B-TP Selection Criteria: The 1N5354B-TP is appropriate as a substitute when higher power dissipation capability (5 W) and lower impedance (2.5 Ohms) provide circuit design advantages. This part is active-status and maintains full RoHS3 compliance. The operating temperature range extends to 150°C, which is suitable for applications not requiring the extended upper temperature limit of the 2M17Z. The 1N5354B-TP is supplied in Cut Tape (CT) packaging format, whereas the 2M17Z is supplied in Tape & Reel (TR) format.

Both parts satisfy the critical electrical and mechanical substitution criteria for 17 V Zener diode applications in through-hole DO-15 configurations.

Frequently Asked Questions (FAQ)

Q: Can the 1N5354B-TP directly replace the 2M17Z in a circuit?

A: The 1N5354B-TP satisfies all critical electrical parameters (17 V nominal Zener voltage, ±5% tolerance, 500 nA reverse leakage) and mechanical requirements (through-hole, DO-15 axial package). The substitute provides enhanced performance with 5 W power dissipation versus 2 W and lower impedance (2.5 Ohms versus 9 Ohms). The operating temperature range of the 1N5354B-TP extends to 150°C, which is lower than the 2M17Z specification of 175°C. Direct substitution is permissible when the circuit operating temperature does not exceed 150°C.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on tape segments cut to specified lengths, typically for manual assembly or lower-volume applications. Both formats contain the same component in identical DO-15 axial packages. Selection between TR and CT depends on assembly process requirements and volume considerations.

Q: Are there impedance differences between the 2M17Z and 1N5354B-TP?

A: Yes. The 2M17Z specifies a maximum impedance of 9 Ohms, while the 1N5354B-TP specifies a maximum impedance of 2.5 Ohms. Lower impedance in the 1N5354B-TP results in improved transient response and lower dynamic resistance during Zener regulation. This characteristic is advantageous in applications requiring fast voltage stabilization or low output impedance.

Q: What compliance certifications apply to both parts?

A: Both the 2M17Z and 1N5354B-TP are RoHS3 compliant, indicating compliance with the Restriction of Hazardous Substances Directive. Both parts have REACH Unaffected status and are classified under ECCN EAR99 for export control purposes. Both parts carry HTSUS code 8541.10.0050 for tariff classification.

Q: Is the 2M17Z suitable for applications requiring operation above 150°C?

A: Yes. The 2M17Z specifies an operating temperature range of -55°C to 175°C, supporting applications requiring sustained operation at temperatures up to 175°C. The 1N5354B-TP, with an upper operating temperature limit of 150°C, is not suitable for such applications. Selection of the 2M17Z is required when the circuit design specifies operation between 150°C and 175°C.
