Overview
The Diotec Semiconductor 1N5370B is a non-planar Zener diode designed for voltage stabilization and regulation applications. It features a DO-201 axial leaded package with a maximum power dissipation of 5 W at 50°C ambient temperature. The device exhibits a nominal Zener voltage of 56 V with a test current of 20 mA. Key electrical characteristics include a dynamic resistance of 35 Ω, a reverse leakage current of 0.5 μA at 280 V, and a maximum surge current capability of 42.6 A for pulses under 8.3 ms. The component operates within a junction temperature range of -50°C to +150°C.
Feature Summary
- High power dissipation capability suitable for robust voltage regulation tasks
- Non-planar technology construction for reliable performance
- Compliant with RoHS directives and REACH regulations
Applications
- Voltage stabilization circuits
- Linear voltage regulators
- Overvoltage protection (uni-directional)
Procurement Notes
Verify the specific ordering suffix when purchasing. Standard versions are commercial/industrial grade. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes qualification status. Confirm that the required automotive or standard grade matches the application's reliability requirements before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a 56 V reference point with high power handling. Ensure the circuit design accounts for the 5 W thermal limit at elevated ambient temperatures. Verify that the dynamic resistance and leakage current specifications meet the precision requirements of the target voltage regulation topology.
Part Context
This part belongs to the 1N5345B through 1N5388B series of Zener diodes manufactured by Diotec Semiconductor. The series utilizes flächendiffundierte (planar diffused) non-planar technology and offers a wide range of Zener voltages from 8.7 V to 200 V. All variants share the same DO-201 mechanical housing and general thermal characteristics.
Replacement Considerations
Cross-reference with other manufacturers' 1N5370B equivalents. Verify pinout compatibility in the DO-201 package. Ensure replacement parts match the 56 V Zener voltage, 5 W power rating, and thermal resistance specifications to maintain circuit integrity.
