Overview
The Diotec Semiconductor 1N5353B is a silicon unidirectional voltage regulator diode utilizing non-planar technology. It provides a nominal Zener voltage of 16 V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 5 W at an ambient temperature of 50°C and operates within a junction temperature range of -50°C to +150°C. Packaged in the DO-201 axial leaded format, it features a test current of 75 mA and a dynamic resistance of 2.5 Ohms.
Feature Summary
- High power dissipation capability up to 5 W
- Standard Zener voltage tolerance graded to international E 24 (~±5%) standard
- Compliant with RoHS directives (excluding exemption 7A-I)
- REACH compliant and conflict minerals compliant
Applications
- Voltage stabilization circuits
- Voltage regulators
- Overvoltage protection applications
Procurement Notes
Verify that the specific part number matches the required voltage rating and tolerance grade. Confirm compliance requirements such as RoHS and REACH status against project specifications. Ensure the package type aligns with the intended through-hole mounting process. Check for any special suffixes if automotive qualification is needed.
Selection Notes
Select this component when a 16 V regulation point is required with high power handling capabilities. Consider the thermal resistance characteristics and derating curves for ambient temperatures exceeding 50°C. Verify that the surge current ratings meet the transient stress conditions of the target circuit design.
Part Context
This component belongs to the 1N5345B through 1N5388B series of 5 Watt Zener diodes manufactured by Diotec Semiconductor. The series covers a wide voltage range from 8.7 V to 200 V. All devices in this family share similar mechanical data, including the DO-201 case outline and standard commercial/industrial grade reliability levels.
Replacement Considerations
Other manufacturers producing JEDEC registered 1N5353B equivalents may be suitable substitutes. Ensure replacement parts match the 16 V nominal voltage, 5 W power rating, and ±5% tolerance. Verify that the physical dimensions and pinout are compatible with existing PCB layouts.
