1N5356BE3/TR12

Overview

The Microchip Technology 1N5356BE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B-1N5388B series. It provides voltage regulation at a nominal Zener voltage of 19 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features an axial lead T-18 package. Electrical characteristics include a maximum reverse current of 0.5 µA and a dynamic impedance of 3.0 Ω.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards

Applications

• Voltage regulation in power supply circuits
