1N5340C/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5340C/TR12 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 6.0 V with a tight tolerance of ±2%, indicated by the 'C' suffix. 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 dynamic impedance of 1.0 Ω, a maximum reverse current of 1.0 µA, and a maximum regulator current of 790 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation circuits requiring precise tolerance
• Power supply reference designs
• Protection against overvoltage conditions

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes when sourcing this component. The 'TR' suffix indicates tape and reel packaging, while '12' typically denotes a specific reel quantity or variant configuration defined by the manufacturer. Confirm RoHS compliance status (e3) if required for your assembly process. Ensure the supplier documentation matches the exact part number to avoid discrepancies in tolerance or packaging specifications.

Single Zener Diodes Selection Notes

Select this component when a 6.0 V reference with ±2% accuracy is required. The 5-watt power dissipation rating allows for higher current handling compared to lower-power Zeners. Consider the thermal resistance of 25 °C/W junction-to-lead when designing heat sinking solutions. The wide operating temperature range makes it suitable for industrial environments where standard commercial parts may fail.

Single Zener Diodes 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 voltage range from 3.3 V to 200 V. The 1N5340C specifically targets applications needing tighter voltage control than the standard ±5% B-suffix devices, offering ±2% tolerance for precision regulation tasks.
