Overview
The Microchip Technology 1N5352E3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 15V with a standard tolerance of ±5%. The device features an axial-lead T-18 package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 2.5 ohms, a maximum reverse current of 1.0 µA, and a maximum surge current capability of 75 amps.
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 mounting terminals for versatile integration
- Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection systems
- Reference voltage generation in electronic instrumentation
Procurement Notes
Verify that the ordering suffix TR13 corresponds to the tape and reel packaging option as specified in the datasheet. Confirm RoHS compliance status via the e3 designation. Ensure the component matches the specific 15V Zener voltage requirement and ±5% tolerance class defined by the B suffix before procurement.
Selection Notes
Select this component when a 5-watt power dissipation rating is required for robust thermal performance. The T-18 axial leaded package is suitable for through-hole mounting on printed circuit boards. Consider the wide operating temperature range and low thermal resistance design for applications requiring reliable operation under high DC currents or demanding environmental conditions.
Part Context
This part belongs to the Microsemi Scottsdale Division 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The 1N5352 variant specifically targets the 15V regulation segment within this extensive lineup of plastic encapsulated devices.
Replacement Considerations
Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series. Military screening options exist using MQ, MX, or MV prefixes for JAN, JANTX, and JANTXV specifications respectively.
