Overview
The 1N4747A B0G is a single silicon planar power Zener diode manufactured by Taiwan Semiconductor Corporation. It provides a nominal reference voltage of 51 V with a maximum dynamic impedance of 95 Ω and a voltage tolerance of ±5%. The device is designed for through-hole mounting in DO-41 packages, featuring isolated case connections and matte tin terminal finishes. It supports a maximum power dissipation of 1 W at an ambient temperature of 25°C, with a specified operating test current of 5 mA. The component operates within a junction temperature range up to 150°C and is compliant with RoHS standards.
Feature Summary
- Utilizes silicon planar technology for stable voltage regulation
- Features glass passivated construction with isolated case connection
- Provides precise voltage tolerance for general-purpose applications
Applications
- Voltage regulation circuits
- Reference voltage sources
- Clipping and protection circuits
Procurement Notes
Verify the specific suffix 'B0G' against official Taiwan Semiconductor documentation to confirm package type and compliance status. Ensure the procurement channel provides valid datasheets matching the manufacturer's specifications. Confirm that the component meets required environmental standards such as RoHS before integration into final assemblies.
Selection Notes
Select this component when a 51 V Zener voltage with ±5% tolerance is required in a through-hole configuration. Consider the 1 W power rating and 95 Ω dynamic impedance for circuit stability. Verify thermal management requirements given the 150°C maximum operating temperature limit and the DO-41 package constraints.
Part Context
This part belongs to the standard 1N47 series of power Zener diodes, widely used for voltage regulation. The 1N4747A variant specifically targets the 51 V segment of this family. The B0G suffix typically denotes specific packaging or tape-and-reel configurations distinct from bulk DO-41 units, requiring verification of physical dimensions and handling methods.
