2M15Z B0G Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M15Z B0G is a 15 V, 2 W Zener diode manufactured by Taiwan Semiconductor Corporation in the DO-204AC (DO-15) axial through-hole package. This component is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Zener diodes of this specification are used in voltage regulation, overvoltage protection, and reference voltage applications in electronic circuits. Substitute parts may be required due to inventory availability, lead time constraints, or application-specific performance requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M15Z B0G is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Zener voltage (Vz) nominal value: 15 V ±5% tolerance
• Package type: DO-204AC / DO-15 axial through-hole configuration
• Mounting type: Through-hole
• RoHS3 compliance status
• Operating temperature range compatibility

Substitute Parts Identified:

The 1N5352B-TP (Micro Commercial Co) is a direct electrical substitute with identical 15 V nominal Zener voltage and ±5% tolerance. This part maintains the same package specification (DO-15 axial) and through-hole mounting type. Both components are RoHS3 compliant and rated for the same operating temperature minimum of -55°C, though the 1N5352B-TP has a maximum operating temperature of 150°C compared to the 2M15Z B0G at 175°C.

The 1N5353B-TP (Micro Commercial Co) is a voltage-variant substitute with a 16 V nominal Zener voltage. This part shares the same package type (DO-15 axial), through-hole mounting, RoHS3 compliance, and operating temperature minimum. The 1 V difference in nominal Zener voltage places this part outside strict electrical equivalence but within the tolerance band for certain applications requiring voltage regulation at slightly elevated levels.

Parameter Comparison

Engineering Selection Recommendations

1N5352B-TP Selection: The 1N5352B-TP is the primary electrical equivalent for the 2M15Z B0G. Both components share identical nominal Zener voltage (15 V) and tolerance (±5%), ensuring functional compatibility in voltage regulation and reference applications. The 1N5352B-TP provides superior power dissipation capability (5 W versus 2 W) and lower impedance (2.5 Ohms versus 7 Ohms), making it suitable for applications requiring higher current handling or lower dynamic impedance. Both parts are RoHS3 compliant and rated for -55°C minimum operation. The maximum operating temperature difference (150°C for 1N5352B-TP versus 175°C for 2M15Z B0G) must be evaluated against specific application thermal requirements.

1N5353B-TP Selection: The 1N5353B-TP is a voltage-variant substitute with 16 V nominal Zener voltage. This part is applicable only in applications where a 1 V higher regulation voltage is acceptable within system design tolerances. The 1N5353B-TP maintains identical package compatibility, through-hole mounting, and RoHS3 compliance. Like the 1N5352B-TP, it offers 5 W power rating and 2.5 Ohms impedance. Selection of this part requires confirmation that the elevated Zener voltage does not compromise circuit performance or safety margins.

Compliance Considerations: All three parts (2M15Z B0G, 1N5352B-TP, and 1N5353B-TP) are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8541.10.0050. Moisture sensitivity level is 1 (unlimited) for all parts, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 1N5352B-TP directly replace the 2M15Z B0G in all applications?

A: The 1N5352B-TP is electrically equivalent for applications requiring 15 V Zener regulation. Both parts share identical nominal voltage and tolerance specifications. The primary consideration is the maximum operating temperature: the 1N5352B-TP is rated to 150°C while the 2M15Z B0G is rated to 175°C. Applications operating above 150°C ambient or junction temperature require the original 2M15Z B0G specification.

Q: What is the difference between the 1N5352B-TP and 1N5353B-TP?

A: The primary difference is Zener voltage: the 1N5352B-TP is rated at 15 V nominal, while the 1N5353B-TP is rated at 16 V nominal. Both maintain ±5% tolerance and identical package specifications. The 1 V difference affects voltage regulation output and must be evaluated against circuit design requirements.

Q: Are all three parts mechanically compatible?

A: Yes. The 2M15Z B0G, 1N5352B-TP, and 1N5353B-TP all use the DO-204AC / DO-15 axial through-hole package with identical pin configuration and physical dimensions. Direct mechanical substitution is possible without PCB modification.

Q: What does the impedance difference mean for circuit performance?

A: The 2M15Z B0G has maximum impedance of 7 Ohms, while both substitute parts (1N5352B-TP and 1N5353B-TP) have maximum impedance of 2.5 Ohms. Lower impedance results in better voltage regulation stability and reduced output impedance variation across the operating current range. Applications sensitive to voltage ripple or transient response benefit from the lower impedance of the substitute parts.

Q: Are there temperature derating considerations for the substitute parts?

A: The 1N5352B-TP and 1N5353B-TP are rated to 150°C maximum junction temperature, compared to 175°C for the 2M15Z B0G. Applications operating in high-temperature environments must confirm that the 150°C maximum rating is sufficient. Power dissipation calculations should account for the specified maximum operating temperature to ensure safe operation.

Q: Do all parts have the same reverse leakage characteristics?

A: No. The 2M15Z B0G specifies 500 nA reverse leakage at 11.4 V, while both substitute parts specify 1 µA reverse leakage (at 11.5 V and 12.2 V respectively). The substitute parts exhibit higher reverse leakage current. Applications requiring minimal leakage current (such as precision reference circuits) should retain the original 2M15Z B0G specification.

Q: Are RoHS and regulatory certifications identical across all three parts?

A: Yes. All three parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0050. Moisture sensitivity level is 1 (unlimited) for all parts. No regulatory or compliance differences exist between the main part and substitutes.
