1N5234B

Single Zener Diodes Overview

The SMC Diode Solutions 1N5234B is a single-channel general-purpose Zener diode with a nominal voltage of 6.2 V and a tolerance of ±5%. It features a maximum power dissipation (Pd) of 500 mW and operates within a temperature range of -65°C to +200°C. The device utilizes an axial leaded package, typically DO-35 or SOD-27 equivalent form factors for through-hole mounting. Key electrical parameters include a test current (It) of 20 mA, a maximum Zener impedance of 7 Ω, and a maximum reverse leakage current of 5 μA. The typical voltage temperature coefficient is approximately 0.04% per °C.

Single Zener Diodes Procurement Notes

Verify the specific package variant (DO-35 vs. SOD-27 style) and RoHS compliance status with the manufacturer, as commercial grades may differ from hermetic versions. Confirm that the supplier provides official datasheets matching the 1N5234B specification sheet to ensure parameter accuracy before integration into designs.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V reference with low impedance and wide thermal stability is required. Ensure the circuit design accommodates the 500 mW power dissipation limit at the highest expected ambient temperature. Consider the axial lead configuration for through-hole assembly processes rather than surface mount alternatives.

Single Zener Diodes Part Context

The 1N5234B belongs to the standard 1N52xx series of Zener diodes, widely recognized for their reliability in discrete semiconductor applications. Manufactured by SMC Diode Solutions, it represents a legacy part number maintained for compatibility in existing designs. The series offers various voltage ratings, with the 1N5234B specifically addressing the 6.2 V niche common in biasing networks.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5234B parts such as Vishay, onsemi, or Rectron. Verify pinout compatibility and package dimensions (DO-35/SOD-27) to ensure mechanical fit. Electrical parameters like Zener impedance and leakage current should be compared against the original design requirements.
