BZT52B62S-TP Equivalent & Substitute Parts

Part Overview

The BZT52B62S-TP is a Zener diode rated at 62 V nominal voltage with 200 mW maximum power dissipation in a surface mount SOD-323 package. Manufactured by Micro Commercial Co, this component is classified as obsolete product status. Due to its obsolete designation, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. The substitute part maintains identical electrical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZT52B62S-TP is determined by strict equivalence across the following critical parameters:

• Zener Voltage (Vz): 62 V nominal with ±2% tolerance
• Power Dissipation: 200 mW maximum
• Impedance: 150 Ohms maximum
• Reverse Leakage Current: 100 nA @ 46 V
• Forward Voltage: 900 mV maximum @ 10 mA
• Package Type: SOD-323 surface mount
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1 (Unlimited)

The substitute part BZT52B62JS-TP matches all electrical specifications and physical package requirements. The primary distinction is product status transition from obsolete to active, with packaging format change from standard to Tape & Reel (TR) configuration.

Parameter Comparison

Engineering Selection Recommendations

The BZT52B62JS-TP is a direct electrical equivalent to the BZT52B62S-TP with full parameter compatibility for all critical zener diode specifications. Selection of the substitute part is supported by the following factors:

Product Status: The substitute part carries active product status, ensuring ongoing manufacturer support, availability, and compliance with current supply chain requirements. The main part is classified as obsolete, limiting future procurement options.

Compliance Certifications: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing and storage protocols.

Electrical Equivalence: All electrical parameters—zener voltage, power rating, impedance, leakage current, and forward voltage—are identical between the main and substitute parts.

Operating Temperature Consideration: The substitute part specifies a maximum junction temperature of 150°C compared to 175°C for the main part. This represents a 25°C reduction in the upper operating limit. Applications requiring sustained operation above 150°C require evaluation against actual thermal design conditions.

Packaging Format: The substitute part is supplied in Tape & Reel (TR) format, standard for high-volume production. Applications requiring alternative packaging formats must be addressed through inventory management or alternative sourcing.

Frequently Asked Questions (FAQ)

Q: Can BZT52B62JS-TP be used as a direct replacement for BZT52B62S-TP in all applications?

A: Yes, for applications operating within the junction temperature range of -55°C to 150°C. All electrical specifications are identical. Applications requiring operation above 150°C junction temperature require thermal analysis to confirm compatibility.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete vs. active) and packaging format (standard vs. Tape & Reel). Electrical specifications and physical package dimensions are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical.

Q: Why is the operating temperature range different?

A: The substitute part specifies a maximum junction temperature of 150°C versus 175°C for the main part. This is a manufacturer specification difference. Confirm that your application thermal design operates within the 150°C limit.

Q: Is the SOD-323 package identical between both parts?

A: Yes. Both parts use the SC-76, SOD-323 surface mount package with identical physical dimensions and PCB footprint compatibility.

Q: What is the significance of Tape & Reel packaging?

A: Tape & Reel (TR) is the standard packaging format for automated assembly and high-volume production. It provides components in continuous tape format suitable for pick-and-place equipment. This is the industry standard for surface mount components.

Q: Can I mix inventory of both parts in production?

A: Yes. Electrical equivalence is complete. Both parts are interchangeable from a circuit design perspective. Tape & Reel packaging is compatible with standard automated assembly processes.

Q: What is the base product number?

A: Both parts share the base product number BZT52B62, indicating they are variants of the same core zener diode design with identical electrical characteristics.
