ZHCS1006TC Equivalent & Substitute Parts

Part Overview

The ZHCS1006TC is a Schottky diode manufactured by Diodes Incorporated, rated for 60V DC reverse voltage and 900mA average rectified current in a surface mount SOT-23-3 package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The ZHCS1006TC remains available in inventory (778 pieces), but its obsolete status requires engineers to transition to functionally equivalent active alternatives.

Engineering Selection Recommendations

The SBR160S23-7 is the direct equivalent substitute for the ZHCS1006TC. Both components are manufactured by Diodes Incorporated and maintain identical electrical ratings and package specifications. The SBR160S23-7 holds active product status, ensuring long-term availability and supply chain continuity compared to the obsolete ZHCS1006TC.

Both parts satisfy ROHS3 compliance and MSL Level 1 requirements. The SBR160S23-7 features an extended operating temperature range (-65°C to 150°C) compared to the ZHCS1006TC maximum junction temperature of 125°C, providing additional thermal margin in applications requiring wider temperature operation.

The capacitance differential (17pF versus 19pF at 25V, 1MHz) falls within acceptable tolerance for rectifier diode applications and does not constitute a functional limitation for standard switching and rectification circuits.

Frequently Asked Questions (FAQ)

Q: Can the SBR160S23-7 directly replace the ZHCS1006TC in existing designs?

A: Yes. Both components share identical voltage ratings (60V), current ratings (900mA), forward voltage characteristics (530mV @ 750mA), and package specifications (SOT-23-3). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between Schottky and Super Barrier technology in these parts?

A: The ZHCS1006TC uses Schottky technology, while the SBR160S23-7 uses Super Barrier technology. Both technologies deliver identical electrical performance within the specified parameters. Super Barrier represents an advanced Schottky variant offering improved characteristics. The electrical equivalence across all critical parameters ensures functional interchangeability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the ZHCS1006TC and SBR160S23-7 are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Both are REACH unaffected and classified under ECCN EAR99.

Q: Why should I transition from ZHCS1006TC to SBR160S23-7?

A: The ZHCS1006TC is classified as obsolete. The SBR160S23-7 is an active product with significantly higher inventory availability (24,351 pieces versus 778 pieces), ensuring reliable long-term supply for production and future orders.

Q: Does the extended temperature range of SBR160S23-7 affect circuit design?

A: No. The SBR160S23-7 operating range (-65°C to 150°C) encompasses the ZHCS1006TC maximum junction temperature of 125°C. The extended range provides additional thermal margin without requiring design modifications.

Q: Are the packages physically identical?

A: Yes. Both components use the TO-236-3 / SC-59 / SOT-23-3 surface mount package. PCB footprints and assembly processes remain unchanged during substitution.

Q: What is the significance of the capacitance difference (17pF vs 19pF)?

A: The 2pF capacitance difference at 25V, 1MHz is negligible for rectifier diode applications. This variance does not impact switching performance, frequency response, or circuit functionality in standard rectification and switching circuits.
