1N4751A B0G

Overview

The Taiwan Semiconductor 1N4751A B0G is a single-channel Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 30 V with a tight tolerance of ±5%. The device operates in a DO-41-2 through-hole package and dissipates up to 1 W of power. Key electrical parameters include a maximum reverse leakage current of 5 µA, a Zener impedance of 40 Ohms, and a test current of 8.5 mA. It supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Glass passivated junction construction for enhanced stability
• Built-in strain relief mechanism within the DO-41 package
• Low inductance design suitable for high-frequency switching

Applications

• Voltage reference circuits
• Overvoltage protection stages
• Clipper and clamper configurations

Procurement Notes

Verify RoHS compliance status directly with the manufacturer or authorized distributors, as documentation indicates detailed verification is required. Confirm lead times and lot traceability before finalizing orders, as supply chain availability may vary by region and production batch.

Selection Notes

Select this component when a standard 30 V regulation point is required in a through-hole assembly. Ensure the circuit can handle the 8.5 mA test current and that the 40 Ohm impedance aligns with noise sensitivity requirements. Verify thermal management capabilities for continuous 1 W dissipation at elevated ambient temperatures.

Part Context

This part belongs to the 1N4751A series of 1 Watt glass-passivated silicon Zener diodes manufactured by Taiwan Semiconductor. It shares the JEDEC registration base with similar components but is distinguished by specific suffix codes indicating packaging and compliance variations.

Replacement Considerations

Cross-reference with onsemi 1N4751A or Micro Commercial Components 1N4751A-AP for equivalent electrical performance. Verify pinout compatibility and package dimensions (DO-41) before substitution.
