2M56Z B0G Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M56Z B0G is an active-status zener diode manufactured by Taiwan Semiconductor Corporation, rated for 56 V nominal zener voltage with 2 W maximum power dissipation. This through-hole component is packaged in DO-204AC (DO-15) axial configuration and is designed for voltage regulation and protection applications in electronic circuits. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit operation within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2M56Z B0G are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Zener voltage rating within ±5% tolerance band
• Power dissipation capability equal to or greater than the main part
• Through-hole mounting configuration with compatible axial package geometry
• Operating temperature range that encompasses or exceeds the main part specification
• Reverse leakage current characteristics suitable for the application voltage range
• Compliance certifications (RoHS3, REACH) matching regulatory requirements

The 1N5369B-TP zener diode is identified as a substitute part. While this part exhibits a lower nominal zener voltage (51 V versus 56 V) and higher maximum power rating (5 W versus 2 W), it operates within the same package family (DO-15 axial) and maintains compatible electrical characteristics for applications where the voltage differential and increased power capability are acceptable within circuit design parameters.

Engineering Selection Recommendations

2M56Z B0G (Primary Part): The 2M56Z B0G remains the primary selection for applications requiring a 56 V nominal zener voltage with 2 W power dissipation in a through-hole DO-15 package. This part is active-status, ROHS3 compliant, and maintains an extended operating temperature range to 175°C. Current inventory of 986 pieces supports immediate availability.

1N5369B-TP (Substitute Part): The 1N5369B-TP is suitable as a substitute when circuit design permits operation at 51 V nominal zener voltage. This part offers increased power dissipation capability (5 W) and lower impedance (27 Ohms versus 55 Ohms), which may provide improved voltage regulation characteristics in certain applications. The substitute part is active-status and ROHS3 compliant. The operating temperature range extends to 150°C, which is 25°C lower than the main part. Inventory availability is higher at 4798 pieces. Both parts maintain identical reverse leakage current specifications and moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can the 1N5369B-TP directly replace the 2M56Z B0G in all applications?

A: Direct replacement depends on circuit voltage requirements. The 1N5369B-TP operates at 51 V nominal zener voltage compared to 56 V for the 2M56Z B0G. Applications requiring precise 56 V regulation must verify that 51 V operation is acceptable. The 5 W power rating of the substitute part exceeds the 2 W requirement of the main part, which is compatible with higher power dissipation scenarios.

Q: Are the packages physically identical?

A: Both parts use DO-15 axial through-hole packaging with compatible mechanical dimensions. Physical installation in PCB footprints designed for DO-204AC (DO-15) axial components is identical for both parts.

Q: What is the temperature operating range difference?

A: The 2M56Z B0G operates from -55°C to 175°C, while the 1N5369B-TP operates from -55°C to 150°C. Applications requiring operation above 150°C must use the main part. Both parts support the full -55°C lower temperature limit.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the 2M56Z B0G and 1N5369B-TP are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level ratings (MSL 1 - Unlimited). Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0050.

Q: What is the impedance difference and does it matter?

A: The 2M56Z B0G has maximum impedance of 55 Ohms, while the 1N5369B-TP has maximum impedance of 27 Ohms. Lower impedance in the substitute part results in better voltage regulation and faster transient response. Applications sensitive to impedance characteristics must evaluate this parameter against circuit requirements.

Q: How do reverse leakage currents compare?

A: Both parts specify 500 nA reverse leakage current. The 2M56Z B0G measures this at 42.6 V, while the 1N5369B-TP measures at 38.8 V. Both specifications indicate equivalent leakage performance within their respective voltage measurement conditions.
