1N5237B TR PBFREE is listed in the Single Zener Diodes range at ChipApex. The manufacturer field lists Central Semiconductor Corp. Its product description is DIODE ZENER 8.2V 500MW DO35. Review the specifications below when checking this part for your BOM.
The Central Semiconductor Corp 1N5237B TR PBFREE is a silicon Zener diode with a nominal voltage of 8.2 V and a tolerance of ±5%. It operates within a power dissipation rating of 500 mW at a lead temperature of 75°C. The device features a maximum reverse current of 3.0 mA at 6.5 V and a maximum Zener impedance of 8.0 Ω at the test current of 20 mA. It utilizes a DO-35 axial through-hole package.
Verify the specific ordering suffix required for your manufacturing process. The 'TR' designation indicates tape and reel packaging, while 'PBFREE' confirms lead-free plating compliance. Confirm that the standard factory packaging quantity aligns with your production volume requirements before placing orders.
Select this component when an 8.2 V reference point with ±5% precision is required in a low-power circuit. Ensure the operating junction temperature remains within the -65°C to +200°C range. Verify that the 500 mW power dissipation limit is sufficient for the expected thermal conditions in the target assembly.
This part belongs to the 1N5221B through 1N5278B series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a wide voltage range from 2.4 V to 170 V, all housed in the DO-35 case. The 'B' suffix specifically denotes the ±5% voltage tolerance characteristic of this product line.
No public confirmed substitute part numbers are available for this component.
The device shall be marked with the prefix 'C' followed by the full part number or the marking code C5237B.
The maximum forward voltage is 1.2 V at a forward current of 200 mA.
