Engineering Selection Recommendations

Parametric Equivalent - Recommended Primary Substitutes:

SK16-LTP (Micro Commercial Co) is the direct parametric equivalent with active product status. This part maintains identical voltage, current, and temperature specifications. The increased capacitance (90pF versus 30pF) is within acceptable tolerance for most applications. This part is recommended as the primary replacement due to manufacturer continuity and proven compatibility.

SK16-TP (SMBSR106) (Micro Commercial Co) is an active variant maintaining identical electrical characteristics to the original SK16-TP, including the 30pF capacitance specification. This part provides direct compatibility with existing designs and is recommended when capacitance specification is critical.

Similar Parts - Secondary Substitutes:

B160B-13-F (Diodes Incorporated) is an active substitute with identical voltage and current ratings. The forward voltage is 20mV lower (700mV versus 720mV), and the operating temperature range is extended (-65°C to 150°C). This part is suitable for applications where improved thermal performance or lower forward voltage drop is beneficial. Higher capacitance (110pF) may affect high-frequency switching performance.

CDBB160-G (Comchip Technology) is an active substitute with matching voltage and current specifications. This part is suitable for applications where manufacturer diversification is required. Capacitance data is not provided; verification against application requirements is necessary.

STPS160U (STMicroelectronics) is an active substitute with identical voltage and current ratings. The forward voltage is significantly lower (670mV versus 720mV), and reverse leakage current is substantially reduced (4µA versus 500µA). This part is suitable for applications requiring improved efficiency and lower leakage characteristics. Operating temperature maximum is not specified; contact manufacturer for complete thermal specifications.

SK36BH (Taiwan Semiconductor Corporation) is a higher-current variant rated for 3A operation. This part is suitable only for applications where the 1A current rating of the SK16-TP is insufficient. The part includes AEC-Q101 automotive qualification and extended operating temperature range (-55°C to 150°C). This part is not recommended as a direct substitute due to current rating mismatch.

All recommended substitutes maintain ROHS3 compliance and fast recovery characteristics (≤ 500ns, > 200mA).

Frequently Asked Questions (FAQ)

Q: Can SK16-LTP be used as a direct replacement for SK16-TP?

A: Yes. SK16-LTP is a parametric equivalent with active product status. Both parts share identical voltage (60V), current (1A), forward voltage (720mV @ 1A), and operating temperature range (-55°C to 125°C). The capacitance difference (90pF versus 30pF) is acceptable for standard rectifier applications. SK16-LTP is the recommended primary substitute.

Q: What is the difference between SK16-TP and SK16-TP (SMBSR106)?

A: Both parts are manufactured by Micro Commercial Co with identical electrical specifications. SK16-TP (SMBSR106) is the active variant of the obsolete SK16-TP. The SMBSR106 designation is an alternative part number for the same component. This part maintains the original 30pF capacitance specification.

Q: Can B160B-13-F replace SK16-TP in all applications?

A: B160B-13-F is a suitable substitute for most applications. The 20mV lower forward voltage (700mV versus 720mV) improves efficiency. The extended operating temperature range (-65°C to 150°C) provides additional thermal margin. However, the higher capacitance (110pF versus 30pF) may affect switching performance in high-frequency circuits. Verify application requirements before substitution.

Q: Why is SK36BH listed as a similar part if it has a different current rating?

A: SK36BH is listed as a similar part due to shared voltage rating (60V) and package (DO-214AA, SMB). However, the 3A current rating makes it unsuitable as a direct replacement for the 1A SK16-TP. This part is included for reference only when higher current capacity is required in redesigned circuits.

Q: What are the key differences between STPS160U and SK16-TP?

A: STPS160U maintains identical voltage (60V) and current (1A) ratings. The forward voltage is significantly lower (670mV versus 720mV), and reverse leakage current is substantially reduced (4µA versus 500µA). These improvements result in better efficiency and lower power dissipation. Operating temperature specifications are not fully provided; contact STMicroelectronics for complete thermal data before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, ensuring compatibility with environmental and regulatory requirements.

Q: Can these parts be used interchangeably on the same PCB?

A: All substitute parts use the DO-214AA (SMB) surface mount package with identical pinout and footprint. Physical PCB compatibility is confirmed. Electrical compatibility depends on application-specific requirements for forward voltage, capacitance, and reverse leakage current. Verify these parameters against circuit design specifications before substitution.

Q: What is the significance of the fast recovery specification (≤ 500ns, > 200mA)?

A: This specification indicates the diode's switching speed and is maintained across all substitute parts. Fast recovery characteristics ensure minimal reverse recovery time, reducing switching losses in power conversion circuits. All listed substitutes meet this specification.

Q: Is capacitance a critical parameter for substitution?

A: Capacitance becomes critical in high-frequency switching applications where junction capacitance affects circuit performance. For standard rectifier applications operating below 1MHz, capacitance variations are typically acceptable. For high-frequency designs, verify capacitance specifications against circuit requirements. SK16-TP and SK16-TP (SMBSR106) maintain the original 30pF specification; SK16-LTP increases to 90pF.
