SMBJ5357B-TP

Single Zener Diodes Overview

The SMBJ5357B-TP is a 5.0 W surface mount silicon Zener diode manufactured by MCC (Micro Commercial Components). It features a nominal Zener voltage of 20 V with a ±5% tolerance, housed in the low-profile DO-214AA (SMB) package. The device operates within a junction temperature range of -55°C to +150°C and exhibits a maximum dynamic impedance of 3 Ω at the test current of 65 mA. It includes a maximum reverse leakage current of 0.5 µA at 15.2 V and supports a maximum non-repetitive surge current of 75 A.

Single Zener Diodes Feature Summary

• Low profile surface mount package designed for accurate placement
• Halogen-free green device compliant with environmental standards
• Lead-free finish meeting UL 94 V-0 flammability rating

Single Zener Diodes Applications

• Voltage regulation circuits
• Transient voltage suppression
• Protection against electrostatic discharge

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized MCC distributors or direct procurement channels to mitigate counterfeit risks. Confirm that the ordering suffix 'TP' indicates tape and reel packaging containing 3,000 pieces per reel. Ensure compliance with RoHS directives and verify specific lot traceability requirements prior to finalizing acquisition orders.

Single Zener Diodes Selection Notes

Select this component when a 20 V regulation point is required in a compact surface mount design. The SMBJ5357B-TP provides robust thermal performance with a 15°C/W junction-to-lead thermal resistance. Consider the 5 W steady-state power dissipation capability and the wide operating temperature range for demanding industrial environments.

Single Zener Diodes Part Context

This part belongs to the SMBJ5338B through SMBJ5388B series of 5.0 W surface mount Zener diodes. The series covers a voltage range from 5.1 V to 200 V, all utilizing the standardized DO-214AA (SMB) footprint. This family allows designers to maintain consistent board layouts across various voltage regulation applications.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' SMBJ5357 variants in the DO-214AA package. Verify that substitute components match the 20 V nominal voltage, 5 W power rating, and ±5% tolerance specifications to ensure circuit compatibility.
