1N5381E3/TR13

Overview

The Microsemi Corporation 1N5381E3/TR13 is a silicon Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 130 V with a ±5% tolerance, indicated by the 'B' suffix. The device features a T-18 axial-lead plastic package and supports a maximum power dissipation of 5.0 watts. Electrical characteristics include a test current of 10 mA, a maximum dynamic impedance of 190 Ohms, and a maximum reverse current of 0.5 µA. The component operates within a temperature range of -65°C to +150°C.

Feature Summary

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

Applications

• Voltage regulation circuits requiring 130 V reference
• Power supply protection against transient overvoltages
• High current DC operation with adequate heat sinking

Procurement Notes

Verify that the part number includes the 'e3' suffix to confirm RoHS compliance and the 'TR' suffix to ensure tape and reel packaging. Confirm the 'B' suffix indicates the required ±5% voltage tolerance. Ensure the supplier source aligns with authorized distribution channels for Microsemi components to guarantee authenticity and traceability.

Selection Notes

Select this component when a 130 V Zener voltage with tight ±5% tolerance is required. The 5-watt power rating allows for high maximum DC currents if adequate heat sinking is provided. Consider the T-18 package dimensions for PCB layout and verify thermal resistance requirements based on the specific mounting method used.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5381 variant specifically targets the 130 V regulation point within this extensive lineup of axial-leaded components.

Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. Military screening levels can be obtained by adding MQ, MX, or MV prefixes to the part number.
