Overview
The Microchip Technology 1N5350BE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 13 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a maximum reverse current of 1.0 µA at 9.4 V. Packaged in an axial T-18 case, it supports tape and reel mounting.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and exhibits minimal voltage change versus current
- Features flexible axial-lead terminals for versatile mounting configurations
Applications
- Voltage regulation circuits requiring 5-watt power dissipation
- Power supply reference applications
- Protection against overvoltage conditions
Procurement Notes
Verify component authenticity by checking manufacturer markings and datasheet alignment. Confirm RoHS compliance status via the e3 suffix designation. Ensure the TR12 suffix matches required tape and reel specifications. Validate thermal management requirements against the specified junction-to-lead thermal resistance.
Selection Notes
Select this component for applications requiring a 13 V Zener reference with ±5% tolerance. Consider the 5-watt power rating and T-18 package size for through-hole implementations. Evaluate thermal derating curves if ambient temperatures exceed standard limits or if heat sinking is not utilized.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip). The series covers voltages from 3.3 V to 200 V. The 'e3' suffix indicates RoHS compliance, while 'TR12' specifies the tape and reel packaging format.
Replacement Considerations
Direct substitutes include other manufacturers' 1N5350B equivalents meeting the same electrical specifications. Verify that any replacement maintains the 5-watt power rating, T-18 package dimensions, and 13 V Zener voltage tolerance.
