1M120Z B0G

Overview

The 1M120Z B0G is a single Zener diode manufactured by Taiwan Semiconductor Corporation, designed for through-hole mounting in the DO-41-2 (DO-204AL) package. It features a nominal Zener voltage of 120 V with a tolerance of 5%. The device supports a power dissipation of 1 W and operates within a temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 550 Ohms at a test current of 2 mA.

Feature Summary

• Provides stable voltage regulation via Zener breakdown mechanism
• Capable of handling high thermal loads up to 150°C junction temperature
• Offers precise voltage tolerance for reliable circuit protection

Applications

• Voltage reference circuits requiring stable DC levels
• Over-voltage protection stages in power supplies
• Clamping applications in signal conditioning paths

Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm RoHS compliance status and REACH SVHC declarations directly with the manufacturer or authorized distributors. Ensure the specific B0G suffix matches your assembly requirements. Validate supply chain reliability as availability may fluctuate.

Selection Notes

Select this component when a 120 V regulation point is required in a through-hole design. The DO-41 package suits standard PCB layouts. Consider the 550 Ohm impedance for noise sensitivity. Compare against other 1M series variants if different voltage ratings are needed. Ensure the 1 W power rating meets the thermal budget of the target application.

Part Context

This part belongs to the 1M120Z series of axial leaded Zener diodes from Taiwan Semiconductor. It shares the DO-41 form factor with other high-power variants in the lineup. The series is engineered for general-purpose voltage regulation tasks. It complements the manufacturer's broader portfolio of rectifiers and transient voltage suppressors.
