1N5336B

Single Zener Diodes Overview

The Good-Ark Semiconductor 1N5336B is a Zener diode from the 1N53xxB series, designed for voltage regulation and protection applications. It features a nominal Zener voltage of 4.3V with a tolerance of ±5%, ensuring precise voltage reference capabilities. The device operates within a DC power dissipation rating of 5W at an ambient temperature of 75°C, supporting high peak reverse power handling. It utilizes a DO-15 axial lead package constructed from UL94V-0 flame retardant epoxy, suitable for through-hole mounting in any orientation. Key electrical parameters include a maximum Zener impedance of 2Ω at the test current (IZT) of 500mA, a leakage current of 10µA at 16.4V, and a junction temperature range spanning from -65°C to +200°C.

Single Zener Diodes Procurement Notes

Verify the specific part number against the manufacturer's official datasheet to confirm the B-suffix indicates a ±5% tolerance. Ensure the procurement documentation explicitly references the 1N53xxB series specifications, particularly the 5W power dissipation rating and DO-15 package dimensions. Cross-check the electrical characteristics table for the 4.3V nominal voltage and associated impedance values to guarantee component authenticity and performance compliance.

Single Zener Diodes Selection Notes

Select this component when a 4.3V Zener reference with ±5% precision is required in a high-power environment. The 5W dissipation rating allows for robust operation in thermal-constrained designs without excessive heatsinking. Consider the DO-15 package size for board space availability and the axial lead configuration for automated or manual through-hole assembly processes compatible with standard PCB layouts.

Single Zener Diodes Part Context

The 1N5336B belongs to the broader 1N53xxB family of Zener diodes manufactured by Good-Ark Semiconductor. This series covers a wide voltage range from 3.3V to 200V, all sharing the same 5W power dissipation capability and DO-15 package form factor. The 'B' suffix consistently denotes the ±5% tolerance variant across the entire product line, distinguishing it from other tolerance grades if available.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 4.3V nominal voltage, ±5% tolerance, 5W power rating, and DO-15 package. Verify that alternative manufacturers specify identical Zener impedance and leakage current limits under comparable test conditions to ensure circuit performance parity.
