The Central Semiconductor Corp 2N5227 TIN/LEAD is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3.6V with a tolerance of ±2% when designated with the 'C' suffix, or ±5% with the 'B' suffix. The device operates within a DO-35 axial leaded glass package and supports a maximum power dissipation of 500mW at 75°C ambient temperature. It withstands junction temperatures ranging from -65°C to +200°C.
Verify the specific suffix (B or C) to confirm voltage tolerance accuracy before procurement. Confirm tin/lead plating compliance if RoHS restrictions apply. Check current availability status as this component type may be subject to discontinuation notices. Ensure the DO-35 package dimensions match the target PCB layout constraints.
Select the appropriate suffix based on required voltage accuracy; use 'C' for tighter tolerances. Verify that the 500mW power rating suits the thermal environment. Consider the operating temperature range limits for high-heat applications. Compare against equivalent series parts if sourcing alternatives are necessary.
This component belongs to the widely used 1N5221 through 1N5281 series of 0.5-watt Zener voltage regulators. These devices provide a broad selection of voltages from 2.4V to 200V. The 2N5227 specifically addresses the low-voltage regulation segment near 3.6V.
The suffix indicates voltage tolerance. The 'B' suffix denotes a ±5% tolerance, while the 'C' suffix provides a tighter ±2% tolerance.
The maximum operating and storage junction temperature is +200°C.
