1N4757A B0G

Overview

The 1N4757A B0G is a 51 V Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal power dissipation of 1 W and operates within a temperature range of -65 °C to +150 °C. The device utilizes a DO-41 (DO-204AL) plastic axial package with a matte tin terminal finish. Electrical characteristics include a maximum dynamic impedance of 95 Ω, a voltage tolerance of ±5%, and a maximum reverse leakage current of 5 µA at a test current of 5 mA.

Feature Summary

• Glass passivated junction for enhanced stability
• Built-in strain relief in the molded plastic package
• Low inductance design suitable for high-frequency applications
• Guaranteed high-temperature soldering capability

Applications

• Voltage regulation circuits
• Clipping and waveform shaping
• Reference voltage generation

Procurement Notes

Verify the specific suffix 'B0G' against the manufacturer's official documentation to confirm exact packing and marking specifications. Confirm RoHS compliance status and lead-free material declarations directly with Taiwan Semiconductor prior to procurement. Ensure the ordering quantity aligns with the manufacturer's standard packaging configurations.

Selection Notes

Select this component when a precise 51 V reference is required in a through-hole configuration. The 1W power rating supports moderate current loads compared to lower-power variants. Verify that the operating environment remains within the specified thermal limits to maintain the ±5% voltage accuracy over the full temperature range.

Part Context

This part belongs to the 1N47xx series of silicon planar power Zener diodes. The series provides a wide selection of voltages from 3.3 V to 100 V. The 'A' suffix typically denotes a tighter ±5% voltage tolerance compared to the standard ±10% version. The device is designed for use in stabilizing and clipping circuits requiring higher power ratings.

Replacement Considerations

Cross-reference with Vishay 1N4757A or Microsemi 1N4757A for equivalent electrical performance. Verify package compatibility and pinout alignment before substitution. Check for differences in maximum operating temperature and leakage current specifications between manufacturers.
