• Identical package configuration: SOT-23-3 (TO-236-3, SC-59)
• Identical surface mount mounting type
• Identical reverse leakage current specification: 100 µA @ 45 V
• Identical fast recovery speed classification: ≤500ns, >200mA
• Identical moisture sensitivity level: MSL 1 (Unlimited)
• Identical compliance certifications: RoHS3 Compliant, REACH Unaffected

The substitute represents a technology advancement from Schottky to Super Barrier diode technology while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SBR160S23-7 is the direct equivalent substitute for the obsolete ZHCS1006TA. Both components are manufactured by Diodes Incorporated and share identical electrical ratings and package specifications. The substitute part is currently in active production status with significantly higher inventory availability (24,351 pieces versus 7,330 pieces for the original part).

Both parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications subject to these standards. The SBR160S23-7 offers an extended operating temperature range (-65°C to 150°C) compared to the ZHCS1006TA maximum junction temperature specification of 125°C, providing additional thermal margin in demanding applications.

The transition from Schottky to Super Barrier technology in the substitute part represents an advancement in diode architecture while preserving all critical electrical parameters required for direct substitution. The capacitance difference of 2pF (17pF versus 19pF at 25V, 1MHz) is within typical component variation and does not affect substitution suitability for standard rectification applications.

Frequently Asked Questions (FAQ)

Q: Can the SBR160S23-7 be used as a direct replacement for the ZHCS1006TA in existing designs?

A: Yes. The SBR160S23-7 meets all electrical and mechanical specifications of the ZHCS1006TA. Both components share identical voltage ratings (60V), current ratings (900mA), forward voltage characteristics (530 mV @ 750 mA), and package configuration (SOT-23-3). No circuit modifications are required.

Q: What is the difference between Schottky and Super Barrier diode technology?

A: Both are fast recovery diode technologies suitable for rectification applications. The Super Barrier technology in the SBR160S23-7 represents a manufacturing advancement that maintains electrical equivalence while offering improved performance characteristics. For the specified electrical parameters, both technologies deliver identical performance.

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

A: No. Both the ZHCS1006TA and SBR160S23-7 are RoHS3 compliant and REACH unaffected. Both carry MSL 1 (Unlimited) moisture sensitivity classification, indicating identical handling and storage requirements.

Q: Why is the operating temperature range different between the two parts?

A: The ZHCS1006TA specifies a maximum junction temperature of 125°C, while the SBR160S23-7 specifies an operating range of -65°C to 150°C. This difference reflects the product specifications provided by the manufacturer. The SBR160S23-7 offers extended thermal operating margin, which may benefit applications with elevated ambient or self-heating conditions.

Q: Is the 2pF capacitance difference between parts significant?

A: No. The capacitance difference (17pF in ZHCS1006TA versus 19pF in SBR160S23-7, both measured at 25V and 1MHz) represents approximately 12% variation and is within normal component tolerance ranges. This difference does not affect substitution suitability for standard rectification circuits.

Q: What is the packaging format difference between the listed options?

A: Both parts are supplied in SOT-23-3 surface mount packages. The SBR160S23-7 is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility in procurement quantities. The physical package dimensions and PCB footprint are identical.

Q: Is the reverse recovery time specification important for substitution?

A: The ZHCS1006TA specifies a reverse recovery time of 12 ns. The SBR160S23-7 does not provide a specific trr value in the available data but is classified as fast recovery (≤500ns, >200mA), which encompasses the ZHCS1006TA specification. Both parts meet fast recovery requirements for standard switching applications.
