• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole integration

Applications

• Voltage regulation circuits requiring 5W power dissipation
• High surge stress environments
• General purpose electronic equipment

Procurement Notes

Verify the specific suffix 'TR12' against official documentation to confirm tape and reel packaging requirements. Confirm RoHS compliance status via the manufacturer datasheet as sourcing channels vary. Ensure thermal management aligns with specified derating curves for optimal performance.

Selection Notes

Select this component for applications requiring a 47V reference with tight ±5% tolerance. Consider the T-18 package dimensions and lead length for PCB layout. Evaluate thermal resistance requirements based on the intended mounting method to ensure operation within the specified junction temperature limits.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series covers voltages from 3.3V to 200V. The 'B' suffix indicates standard ±5% tolerance, while 'e3' denotes RoHS compliance. The 'TR12' suffix specifies the tape and reel packaging configuration.

Replacement Considerations

Consult the official datasheet for equivalent parts within the 1N5333B-1N5388B series. Verify that substitute components match the 47V Zener voltage, 5W power rating, and T-18 package specifications.
