1N5533B TR PBFREE

Overview

The 1N5533B TR PBFREE is a single Zener diode manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 13 V with a tolerance of ±5%. The device is rated for a power dissipation of 400 mW and operates in the through-hole DO-35 axial package. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 2 V and a Zener impedance of 1 Ohm. The component supports a test current of 20 mA and functions within an operating temperature range from -65 °C to +175 °C.

Feature Summary

• Provides stable voltage regulation via Zener breakdown mechanism
• Designed for surface mount or through-hole integration using standard axial leads
• Constructed with lead-free materials compliant with environmental standards

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in signal paths
• Biasing networks for transistor amplifiers

Procurement Notes

Verify the specific suffix configuration against the manufacturer's latest documentation to ensure compatibility with required testing conditions. Confirm that the procurement channel provides original manufacturer packaging to maintain component integrity. Cross-reference the date code with production records to validate freshness. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet prior to assembly processing.

Selection Notes

Select this component when a 13 V reference point is required in low-power applications. The DO-35 package suits designs needing robust mechanical mounting for axial leads. Evaluate thermal management requirements as the 400 mW rating limits high-current usage. Compare leakage specifications against circuit sensitivity thresholds to ensure noise performance meets system demands during reverse bias operation.

Part Context

This part belongs to Central Semiconductor's discrete diode portfolio, specifically within the Zener diode category. The series offers various voltage options packaged in standard axial forms. These components are engineered for general-purpose electronic applications requiring reliable voltage clamping or referencing capabilities across industrial and commercial environments.

Replacement Considerations

Substitute parts must match the 13 V Zener voltage, 400 mW power rating, and DO-35 package outline. Verify equivalent Zener impedance and leakage current specifications to maintain circuit stability. Ensure the replacement component supports the same operating temperature range and utilizes compatible soldering techniques for axial lead attachment.
