SK16 Schottky Diode Equivalent & Substitute Parts

Part Overview

The SK16 is an active Schottky rectifier diode manufactured by Diotec Semiconductor, rated for 60 V DC reverse voltage and 1 A average rectified current in a surface mount SMA/DO-214AC package. This component is designed for fast recovery applications with switching speeds ≤ 500 ns and forward voltage of 700 mV at 1 A. Equivalent and substitute parts are identified based on matching or exceeding the electrical specifications and mechanical compatibility requirements of the original device.

Substitute Part Grouping Explanation

Substitute parts for the SK16 are classified into two categories based on electrical and mechanical compatibility:

Category 1: Electrical Equivalents with Package Variation Parts PMEG6010ER,115 and PMEG6010ETR,115 (Nexperia USA Inc.) maintain the same 60 V reverse voltage and 1 A current rating with identical fast recovery speed characteristics. These devices are functionally equivalent but use the SOD-123W surface mount package instead of the SMA/DO-214AC package. Substitution in this category requires PCB layout redesign to accommodate the different package footprint.

Category 2: Higher Current Rating with Same Package Part SK36A-LTP (Micro Commercial Co) maintains the same 60 V reverse voltage and SMA/DO-214AC package form factor but provides 3 A average rectified current capacity. This part is a direct mechanical substitute with enhanced electrical performance and can be used in applications where higher current handling is required or beneficial.

Key Parameters Determining Substitution:

• Voltage - DC Reverse (Vr) (Max): 60 V (required match)
• Technology: Schottky (required match)
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io) (required match)
• Mounting Type: Surface Mount (required match)
• Package / Case: DO-214AC/SMA or SOD-123W (package-dependent substitution)

Parameter Comparison

Engineering Selection Recommendations

For Direct Package Compatibility (SMA/DO-214AC): The SK36A-LTP maintains identical mechanical compatibility with the SK16 and can be installed without PCB redesign. This part is suitable for applications where the original 1 A current rating is insufficient or where design margin improvement is required. The SK36A-LTP is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements.

For Electrical Optimization with Package Change: The PMEG6010ETR,115 offers superior electrical performance with lower forward voltage (530 mV vs. 700 mV at 1 A) and significantly reduced reverse leakage current (60 µA vs. 500 µA at 60 V). This part requires PCB layout modification to accommodate the SOD-123W package. The PMEG6010ETR,115 provides the highest maximum junction temperature rating (175°C) and is ROHS3 compliant and REACH unaffected.

The PMEG6010ER,115 provides identical electrical characteristics to the PMEG6010ETR,115 with a maximum junction temperature of 150°C and is also ROHS3 compliant and REACH unaffected.

All substitute parts maintain the required 60 V reverse voltage rating, Schottky technology, and fast recovery speed characteristics essential for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can PMEG6010ER,115 or PMEG6010ETR,115 be used as direct replacements for SK16 without PCB modification?

A: No. While these Nexperia parts are electrically equivalent, they use the SOD-123W package instead of the SMA/DO-214AC package. PCB footprint redesign is required for mechanical installation.

Q: What is the primary advantage of using SK36A-LTP as a substitute for SK16?

A: The SK36A-LTP maintains the same SMA/DO-214AC package footprint, allowing direct PCB installation without layout changes. It provides 3 A current capacity compared to the SK16's 1 A rating, offering increased design margin and thermal performance in the same physical form factor.

Q: Are all substitute parts compliant with current regulatory standards?

A: PMEG6010ER,115, PMEG6010ETR,115, and SK36A-LTP are all ROHS3 compliant and REACH unaffected. The original SK16 has vendor-undefined REACH status and not-applicable RoHS status.

Q: How do the forward voltage characteristics compare between SK16 and its substitutes?

A: The SK16 has a forward voltage of 700 mV at 1 A. The Nexperia PMEG6010 series (both ER and ETR variants) have lower forward voltage at 530 mV at 1 A, resulting in reduced power dissipation. The SK36A-LTP has a forward voltage of 750 mV at 3 A.

Q: What is the difference between PMEG6010ER,115 and PMEG6010ETR,115?

A: Both parts are electrically identical with 60 V reverse voltage, 1 A current rating, and 530 mV forward voltage. The primary difference is maximum junction temperature: PMEG6010ER,115 is rated to 150°C, while PMEG6010ETR,115 is rated to 175°C. The PMEG6010ETR,115 also specifies a reverse recovery time of 4.4 ns.

Q: Can SK36A-LTP be used in applications originally designed for 1 A operation?

A: Yes. The SK36A-LTP is rated for 3 A operation and maintains the same 60 V reverse voltage and fast recovery characteristics. It is mechanically and electrically compatible with SK16 applications and provides additional current capacity without performance degradation.

Q: What packaging formats are available for these substitute parts?

A: SK16 is supplied in Tape & Reel (TR) format. PMEG6010ER,115 and PMEG6010ETR,115 are supplied in Cut Tape (CT) & Digi-Reel® format. SK36A-LTP is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format selection depends on assembly process requirements and volume specifications.
