1N5356E3/TR8

Overview

The Microchip Technology 1N5356E3/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation with a nominal Zener voltage of 19V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum reverse current of 0.5 µA at 13.7V and a dynamic impedance of 3.0 ohms.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for secure installation
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation circuits requiring 5W power dissipation
• Power supply protection against transient overvoltages
• Reference voltage generation in electronic systems

Procurement Notes

Verify the specific suffix configuration when ordering, as the e3 designation indicates RoHS compliance while TR8 denotes tape and reel packaging. Confirm that the component meets all required environmental standards for your application. Ensure proper heat sinking is utilized to maintain performance within the specified thermal limits during operation.

Selection Notes

Select this component for applications requiring precise voltage clamping with a 19V nominal rating. Consider the ±5% tolerance and low dynamic impedance for accurate regulation needs. Evaluate the thermal resistance and power derating curves to ensure adequate cooling solutions are implemented for reliable long-term performance under varying load conditions.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage range from 3.3V to 200V, offering various tolerance options identified by suffix letters. These devices are designed for robust performance in demanding environments with high surge capabilities.

Replacement Considerations

Equivalent parts within the 1N5333B-1N5388B series may be considered if voltage and tolerance match. Verify mechanical dimensions and terminal plating compatibility. Cross-reference datasheets for thermal characteristics and surge current ratings to ensure functional equivalence.
