Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ZHCS506TC are classified based on electrical parameter compatibility and physical package equivalence. The primary substitution criteria are:

Parametric Equivalents maintain identical or superior electrical specifications across all critical parameters: reverse voltage rating (Vr), average rectified current (Io), forward voltage drop (Vf), reverse recovery time (trr), reverse leakage current, and junction capacitance. These parts are pin-compatible and functionally interchangeable within the same circuit design without modification.

Manufacturer Recommended Alternatives may exhibit different electrical characteristics while maintaining functional compatibility within specific application contexts. These parts require engineering evaluation to confirm suitability for the intended circuit.

The key parameters determining substitution eligibility are:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 60 V
• Current - Average Rectified (Io): Must equal or exceed 500 mA
• Package / Case: Must be TO-236-3, SC-59, or SOT-23-3
• Technology: Schottky diode type
• Mounting Type: Surface Mount

Parameter Comparison

Engineering Selection Recommendations

ZHCS506TA is the primary substitute for ZHCS506TC. This part is manufactured by Diodes Incorporated and maintains identical electrical specifications across all critical parameters. The ZHCS506TA is classified as active product status, ensuring long-term availability and supply chain continuity. Both parts share the same base product number (ZHCS506) and are fully compatible at the circuit level. The primary distinction is packaging format: ZHCS506TC is supplied in standard packaging, while ZHCS506TA is supplied in Tape & Reel (TR) format. Both parts carry ROHS3 compliance, REACH unaffected status, and MSL 1 rating.

BAS70E6327HTSA1 is a manufacturer-recommended alternative manufactured by Infineon Technologies. This part exhibits different electrical characteristics that limit its direct substitution capability. The BAS70E6327HTSA1 is rated for 70 V reverse voltage (exceeding the 60 V requirement) but is limited to 70 mA average rectified current, which is significantly below the 500 mA specification of the ZHCS506TC. The forward voltage drop is higher at 1 V @ 15 mA compared to 630 mV @ 500 mA. The reverse recovery time is superior at 100 ps, and reverse leakage current is lower at 100 nA @ 50 V. This part is suitable only for applications where current requirements do not exceed 70 mA and where the higher forward voltage drop is acceptable. The BAS70E6327HTSA1 provides extended operating temperature range (-55°C to 125°C) compared to the 125°C maximum of the ZHCS506TC.

Frequently Asked Questions (FAQ)

Q: Can ZHCS506TA be used as a direct replacement for ZHCS506TC?

A: Yes. The ZHCS506TA is a parametric equivalent with identical electrical specifications. Both parts are rated for 60 V reverse voltage, 500 mA average rectified current, and 630 mV forward voltage drop at 500 mA. The parts are pin-compatible in SOT-23-3 packages and require no circuit modifications. The primary difference is packaging format (Tape & Reel for ZHCS506TA versus standard packaging for ZHCS506TC).

Q: Is BAS70E6327HTSA1 suitable for all applications using ZHCS506TC?

A: No. The BAS70E6327HTSA1 has a maximum average rectified current rating of 70 mA, which is insufficient for applications requiring 500 mA. This part is suitable only for low-current applications where circuit requirements do not exceed 70 mA. The higher forward voltage drop (1 V @ 15 mA) may also affect circuit performance in voltage-sensitive applications.

Q: Are all three parts pin-compatible?

A: Yes. All three parts (ZHCS506TC, ZHCS506TA, and BAS70E6327HTSA1) use the TO-236-3, SC-59, SOT-23-3 package format and are physically pin-compatible. However, electrical compatibility must be verified based on application requirements.

Q: What is the difference between ZHCS506TC and ZHCS506TA packaging?

A: ZHCS506TC is supplied in standard packaging format, while ZHCS506TA is supplied in Tape & Reel (TR) format. Tape & Reel packaging is designed for automated assembly processes and high-volume production. Both parts contain identical components and specifications.

Q: Do all substitute parts meet RoHS and REACH compliance requirements?

A: Yes. ZHCS506TC, ZHCS506TA, and BAS70E6327HTSA1 are all ROHS3 compliant and REACH unaffected. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the operating temperature range for each part?

A: ZHCS506TC and ZHCS506TA are rated for maximum junction temperature of 125°C. BAS70E6327HTSA1 provides extended operating temperature range from -55°C to 125°C, offering superior performance in low-temperature environments.
