The 1N5237B-T is a 500mW epitaxial Zener diode from Diodes Incorporated, part of the 1N5221B-1N5267B series. It features a nominal Zener voltage of 8.2V with a ±5% tolerance, corresponding to a voltage range of 7.79V to 8.61V at a test current of 20mA. The diode offers a maximum impedance of 8Ω at IZT and 500Ω at IZK (0.25mA).
Designed for general-purpose voltage regulation and clamping applications, the device can dissipate up to 500mW of power (with leads at 75°C, 9.5mm from case). It operates over a junction temperature range of -65°C to +175°C and has a thermal resistance of 300°C/W junction-to-ambient.
The 1N5237B-T is housed in a hermetically sealed DO-35 glass package with axial leads and a tin-silver (Sn96.5Ag3.5) solderable finish. It is RoHS3 compliant and has an MSL of Level 1. The part is supplied in tape and reel packaging (10,000 units per reel). Note: This part is discontinued and Diodes Incorporated recommends the MMSZ52xxB series as a replacement.
