This document is about the electrical characteristics of the 1N52 series Zener diodes from LESHAN RADIO COMPANY, LTD. 2B–1/2. The document lists parameters of different models of Zener diodes, including nominal Zener voltage, max Zener voltage temperature coefficient, max reverse leakage current, etc.
This document provides the electrical characteristics for the Leshan Radio Company 1N52 Series Zener Diodes, covering models from 1N5221B through 1N5272B. The specifications are based on DC measurements at thermal equilibrium with a lead length of 3/8 inches and a heat sink thermal resistance of 30°C/W.
| Package Type | DO-35 |
|---|---|
| Lead Length | 3/8 inches |
| Heat Sink Thermal Resistance | 30°C/W |
| Max Forward Voltage (VFmax) | 1.1V @ IF=200mA |
| Tolerance Suffix B | ±5% |
| Tolerance Suffix C | ±2% |
| Tolerance Suffix D | ±1% |
Suffix B indicates a voltage tolerance of ±5%, suffix C is ±2%, and suffix D is ±1%.
The maximum forward voltage (VFmax) is 1.1V when the forward current is 200mA.
