2M27Z Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M27Z is an active-status zener diode manufactured by Taiwan Semiconductor Corporation, rated for 27 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, design flexibility, or application-specific power handling requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M27Z is permissible when the following electrical and mechanical parameters are maintained or exceeded:

Critical Matching Parameters:

• Voltage - Zener (Nom): 27 V (exact match required)
• Tolerance: ±5% (exact match required)
• Current - Reverse Leakage @ Vr: 500 nA @ 20.6 V (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: DO-204AC, DO-15, Axial (exact match required)

Allowable Substitution Criteria:

• Power - Max: Equal to or greater than 2 W
• Impedance (Max): Equal to or less than 18 Ohms
• Operating Temperature Range: Must encompass or exceed -55°C to 175°C
• RoHS and REACH compliance status must be maintained

The 1N5361B-TP meets all critical matching parameters and exceeds power dissipation capability, making it a valid substitute for applications where higher power handling is acceptable or required.

Engineering Selection Recommendations

2M27Z Selection Criteria:

• Applications requiring maximum operating temperature of 175°C
• Designs specified for 2 W power dissipation with no margin requirement
• Tape & Reel packaging format for automated assembly processes
• Taiwan Semiconductor Corporation device qualification requirements

1N5361B-TP Selection Criteria:

• Applications where 5 W power dissipation capability provides design margin
• Circuits operating at maximum temperatures up to 150°C
• Cut Tape packaging format acceptable for assembly processes
• Micro Commercial Co device qualification requirements
• Lower impedance (5 Ohms vs. 18 Ohms) beneficial for voltage regulation stability

Both parts maintain ROHS3 compliance, REACH unaffected status, and identical zener voltage and tolerance specifications. Selection between these parts depends on thermal operating range requirements and power dissipation margin needs within the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 1N5361B-TP replace the 2M27Z in all applications?

A: The 1N5361B-TP is electrically compatible for applications operating at temperatures up to 150°C. Applications requiring operation above 150°C must use the 2M27Z, which is rated to 175°C. The substitute part's higher power rating (5 W vs. 2 W) and lower impedance (5 Ohms vs. 18 Ohms) are compatible with circuits designed for the 2M27Z.

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

A: The 1N5361B-TP has lower maximum impedance (5 Ohms) compared to the 2M27Z (18 Ohms). Lower impedance provides better voltage regulation characteristics and faster transient response in zener regulation circuits. This difference does not prevent substitution; it represents an improvement in performance.

Q: Are the packaging formats interchangeable?

A: Both parts use DO-15 axial through-hole packages and are mechanically compatible for circuit board insertion. The 2M27Z is supplied in Tape & Reel format, while the 1N5361B-TP is supplied in Cut Tape format. These packaging differences affect handling and assembly processes but do not affect electrical performance or mechanical fit.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 2M27Z and 1N5361B-TP are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What is the reverse leakage current specification?

A: Both parts specify 500 nA maximum reverse leakage current measured at 20.6 V. This parameter is identical and ensures equivalent leakage performance in applications where reverse bias leakage is a design consideration.

Q: How do the zener voltage tolerances compare?

A: Both parts are specified with ±5% tolerance on the 27 V nominal zener voltage. This tolerance is identical and ensures equivalent voltage regulation accuracy in circuit applications.
