Parameter Comparison

Engineering Selection Recommendations

RBR1L60ATE25 (Rohm Semiconductor): This part matches the SS16-HF in voltage rating (60V) and current rating (1A) with identical package (DO-214AC/SMA). The RBR1L60ATE25 demonstrates superior forward voltage performance (530 mV vs. 700 mV @ 1A) and lower reverse leakage current (75 µA vs. 300 µA @ 60V). However, this part carries "Not For New Designs" status, limiting its suitability for new product development. ROHS3 compliance and MSL 1 rating match the primary part. This substitute is suitable for legacy system maintenance or replacement applications where design freeze conditions apply.

SK36A-LTP (Micro Commercial Co): This part exceeds the SS16-HF current rating at 3A versus 1A, maintaining the 60V voltage specification and DO-214AC/SMA package. The SK36A-LTP is classified as Active product status, supporting new design implementations. Operating temperature range (-50 to 125°C) encompasses the SS16-HF specification. Forward voltage at rated current (750 mV @ 3A) is comparable to the primary part. Reverse leakage current (500 µA @ 60V) exceeds the SS16-HF specification but remains within acceptable Schottky diode parameters. This substitute provides current margin for applications requiring higher current capacity within the same voltage class and package footprint.

SS26S-M3/61T (Vishay General Semiconductor - Diodes Division): This part provides 2A current rating, exceeding the SS16-HF 1A specification while maintaining 60V voltage rating and DO-214AC/SMA package compatibility. Active product status supports new design applications. Operating temperature range (-65 to 150°C) extends beyond the SS16-HF specification. Forward voltage (700 mV @ 2A) matches the primary part specification. Reverse leakage current (400 µA @ 60V) exceeds the SS16-HF but remains within acceptable parameters. This substitute offers current margin and extended temperature performance for demanding thermal environments.

Frequently Asked Questions (FAQ)

Q: Can RBR1L60ATE25 be used as a direct replacement for SS16-HF in new product designs?

A: RBR1L60ATE25 carries "Not For New Designs" status. While electrical parameters are compatible (60V, 1A, DO-214AC package), this designation indicates the manufacturer does not recommend this part for new circuit implementations. Use this substitute only for legacy system maintenance or replacement applications where design freeze conditions apply.

Q: What is the primary advantage of SK36A-LTP over SS16-HF?

A: SK36A-LTP provides 3A average rectified current compared to SS16-HF's 1A rating, while maintaining identical 60V voltage specification and DO-214AC/SMA package. This higher current capacity enables use in applications requiring greater current handling within the same voltage class and physical footprint. Active product status supports new design implementations.

Q: Are all substitute parts compatible with the SS16-HF PCB footprint?

A: Yes. All substitute parts (RBR1L60ATE25, SK36A-LTP, SS26S-M3/61T) use the DO-214AC (SMA) package, which maintains identical PCB footprint and land pattern compatibility with SS16-HF. No PCB layout modifications are required for mechanical substitution.

Q: How do reverse leakage current differences affect circuit performance?

A: SS16-HF specifies 300 µA reverse leakage @ 60V. RBR1L60ATE25 (75 µA) provides superior leakage performance, while SK36A-LTP (500 µA) and SS26S-M3/61T (400 µA) exceed the primary part specification. In low-current or high-impedance circuits, lower leakage current reduces parasitic current paths. In standard rectification applications, all specified leakage values remain within acceptable Schottky diode performance ranges.

Q: Which substitute part is recommended for high-temperature applications?

A: SS26S-M3/61T and RBR1L60ATE25 both support operating temperatures up to 150°C, compared to SS16-HF's 125°C maximum. SS26S-M3/61T is preferred for new designs due to Active product status. For applications requiring sustained operation above 125°C, these parts provide extended thermal margin within the 60V voltage class.

Q: What is the significance of forward voltage differences between substitute parts?

A: Forward voltage affects power dissipation and circuit efficiency. RBR1L60ATE25 (530 mV @ 1A) demonstrates lower forward voltage than SS16-HF (700 mV @ 1A), reducing power loss in rectification circuits. SK36A-LTP and SS26S-M3/61T maintain comparable forward voltage to the primary part. Lower forward voltage improves efficiency but does not affect functional compatibility in standard rectifier applications.

Q: Can substitute parts with higher current ratings (SK36A-LTP, SS26S-M3/61T) be used in 1A circuits?

A: Yes. Higher current-rated parts operate safely at lower current levels. SK36A-LTP (3A) and SS26S-M3/61T (2A) function correctly in 1A circuits, providing current margin and potential thermal performance benefits. No circuit modifications are required. The 60V voltage rating and DO-214AC package remain identical across all parts.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts (RBR1L60ATE25, SK36A-LTP, SS26S-M3/61T) carry ROHS3 Compliant status, matching the SS16-HF specification. All parts maintain MSL 1 (Unlimited) moisture sensitivity level, enabling standard PCB assembly and storage procedures without special handling requirements.
