Overview
The Microsemi Corporation 1N5384B is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 160 V with a ±5% tolerance, indicated by the B suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial-lead package. Key electrical characteristics include a maximum dynamic impedance of 350 Ohms, a maximum reverse current of 0.5 µA, and a maximum regulator current of 29.4 mA.
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 through-hole applications
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack
Applications
- Voltage regulation circuits
- Overvoltage protection
- High reliability military screening levels (JAN, JANTX, JANTXV)
Procurement Notes
Verify the specific manufacturer source, as this component has been produced by multiple entities including Microsemi and Microchip Technology. Confirm RoHS compliance status, as non-compliant versions exist alongside e3 compliant variants. Ensure the ordering suffix matches the required tolerance and packaging format before procurement.
Selection Notes
Select the 1N5384B for applications requiring 160 V regulation with a 5 W power dissipation rating. Ensure adequate heat sinking is provided to maintain operation within the specified thermal resistance limits. Consider tighter tolerance options like the 1N5384C or 1N5384D if stricter voltage accuracy is required.
Part Context
This component belongs to the 1N5333B-1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 V to 200 V. These plastic encapsulated devices are designed for high maximum DC currents when adequately heat sunk.
Replacement Considerations
Surface mount equivalents such as SMBJ5384B or SMBG5384B are available. Verify that any replacement maintains the required 5 W power rating and 160 V Zener voltage specifications.
