The 1N5281B is a Zener voltage regulator diode from the 1N5221-1N5281B series, offering a nominal Zener voltage of 200V with ±5% tolerance. It is rated for 500mW power dissipation and features a forward voltage of 1.5V at 200mA. Reverse leakage current is 100nA at 152V.
The device is housed in a DO-35 (DO-204AH) glass package with axial leads for through-hole mounting. It operates over a junction temperature range of -65°C to +175°C, with thermal resistance of 250°C/W junction-to-lead and 310°C/W junction-to-ambient on standard FR4 PCB with 4mm² copper pads.
Designed for low-power voltage regulation, the 1N5281B is ESD nonsensitive per MIL-STD-750 and inherently radiation hard. Typical applications include voltage reference, overvoltage protection, and clamping in consumer, industrial, and military-grade circuits.
