1M130Z B0G Zener Diode Equivalent & Substitute Parts

Part Overview

The 1M130Z B0G is a 130 V, 1 W Zener diode manufactured by Taiwan Semiconductor Corporation in the DO-204AL (DO-41) axial through-hole package. This component is classified as discontinued at DiGi Electronics, with 959 units currently in stock. The part operates across a temperature range of -55°C to 150°C and maintains ±5% voltage tolerance. Due to its discontinued status, identifying equivalent and substitute Zener diodes with compatible electrical and mechanical specifications is necessary for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1M130Z B0G is determined by the following critical parameters:

Primary Substitution Criteria:

• Zener voltage: 130 V nominal
• Voltage tolerance: ±5%
• Package type: DO-204AL (DO-41) axial through-hole
• Operating temperature range: -55°C to 150°C minimum
• RoHS3 compliance

Secondary Compatibility Factors:

• Power rating: Equal to or greater than 1 W
• Impedance (Zzt): Maximum 800 Ohms acceptable
• Reverse leakage current: Specified at comparable voltage reference points

Substitute parts are grouped into two categories: direct equivalents from the same manufacturer with identical specifications, and functionally compatible alternatives from other manufacturers with enhanced power ratings or improved electrical characteristics that maintain backward compatibility within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - Recommended Primary Substitute:

The 1M130Z A0G from Taiwan Semiconductor Corporation is the direct equivalent to the 1M130Z B0G. Both parts share identical electrical specifications (130 V nominal, 1 W power rating, ±5% tolerance, 700 Ohms maximum impedance) and mechanical packaging (DO-204AL through-hole axial). The 1M130Z A0G maintains active product status with 865 units in stock, providing immediate availability and design continuity. This part is the preferred substitute when direct replacement is required.

Enhanced Alternative - Vishay Z4KE130A Series:

The Z4KE130A-E3/54 and Z4KE130A-E3/73 from Vishay General Semiconductor - Diodes Division are functionally compatible alternatives with enhanced specifications. Both variants provide 130 V nominal Zener voltage with ±5% tolerance in the same DO-204AL package. The Vishay parts offer increased power dissipation (1.5 W versus 1 W), higher impedance tolerance (800 Ohms maximum), and superior reverse leakage characteristics (500 nA at 99.2 V versus 5 µA at 98.8 V). These parts are suitable for applications requiring improved thermal performance or lower leakage current. Both Z4KE130A variants maintain active status and full RoHS3 compliance.

Selection Basis:

All substitute parts meet the mandatory criteria of 130 V nominal voltage, ±5% tolerance, DO-204AL through-hole packaging, -55°C to 150°C operating temperature range, and RoHS3 compliance. The choice between direct equivalent and enhanced alternatives depends on application-specific requirements for power dissipation and leakage current performance.

Frequently Asked Questions (FAQ)

Q: Can the 1M130Z A0G directly replace the 1M130Z B0G in existing designs?

A: Yes. The 1M130Z A0G is a direct equivalent with identical electrical and mechanical specifications. No circuit modifications are required. Both parts feature 130 V nominal Zener voltage, 1 W power rating, ±5% tolerance, and DO-204AL through-hole axial packaging.

Q: What is the difference between the Taiwan Semiconductor 1M130Z A0G and the Vishay Z4KE130A series?

A: The primary differences are power rating and reverse leakage current. The 1M130Z A0G matches the original 1M130Z B0G at 1 W and 5 µA leakage. The Vishay Z4KE130A parts provide 1.5 W power rating and 500 nA leakage current, offering enhanced thermal capability and lower leakage performance while maintaining the same 130 V nominal voltage and ±5% tolerance.

Q: Are the Vishay Z4KE130A-E3/54 and Z4KE130A-E3/73 interchangeable with each other?

A: Yes. Both Vishay parts (Z4KE130A-E3/54 and Z4KE130A-E3/73) share identical electrical specifications and DO-204AL packaging. The designation suffix indicates different packaging configurations (tape & reel versus bulk), but electrical performance is equivalent.

Q: Can I use a higher power-rated Zener diode as a substitute?

A: Yes, within the specified parameter envelope. The Vishay Z4KE130A series at 1.5 W is compatible with applications designed for the 1 W 1M130Z B0G. Higher power ratings provide additional thermal margin and do not degrade circuit performance when voltage and tolerance specifications remain constant.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts listed (1M130Z A0G, Z4KE130A-E3/54, Z4KE130A-E3/73) are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (unlimited) for all parts.

Q: Does the DO-204AL package differ from DO-41?

A: No. DO-204AL and DO-41 are equivalent designations for the same axial through-hole package. All substitute parts use this identical package format, ensuring mechanical compatibility in PCB layouts and through-hole mounting applications.

Q: Why is the 1M130Z B0G discontinued?

A: The 1M130Z B0G is listed as discontinued at DiGi Electronics. The 1M130Z A0G from the same manufacturer provides continuity with identical specifications and active product status, ensuring long-term availability for new designs and production runs.
