SS36 R6 Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS36 R6 is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 60 V DC reverse voltage and 3 A average rectified current in a DO-214AB (SMC) surface mount package. This component is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute parts for ongoing design requirements and production needs. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts offer compatible performance within the same application category with minor parameter variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS36 R6 is determined by the following critical parameters: reverse voltage rating (60 V minimum), average rectified current capacity (3 A minimum), fast recovery Schottky technology, DO-214AB surface mount package compatibility, and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Substitute parts are grouped into two categories:

Parametric Equivalent: Parts with identical electrical specifications and operating temperature range, differing only in packaging format or product status.

Similar Substitute: Parts with compatible voltage and package specifications but variations in current rating, forward voltage characteristics, or maximum junction temperature. These parts function within the same application space with acceptable parameter deviations.

Parameter Comparison

Engineering Selection Recommendations

SS36H (Parametric Equivalent): This part is the primary replacement for the discontinued SS36 R6. It maintains identical electrical specifications, operating temperature range, and package format. The SS36H is manufactured by the same supplier (Taiwan Semiconductor Corporation) and carries active product status with AEC-Q101 automotive qualification. This part is suitable for direct substitution in all applications where the SS36 R6 was specified.

CDBC360-G (Similar Substitute): This Comchip Technology part provides equivalent voltage and current ratings with a 50 mV improvement in forward voltage (700 mV vs. 750 mV @ 3 A). The maximum junction temperature is rated at 125°C, which is 25°C lower than the SS36 R6. This part is suitable for applications where thermal headroom is not a limiting factor and the improved forward voltage characteristic is beneficial. ROHS3 compliance and MSL 1 rating are maintained.

STPS5L60S (Similar Substitute): This STMicroelectronics part offers a higher current rating (5 A vs. 3 A) and superior forward voltage performance (520 mV @ 5 A). The reverse leakage current is reduced to 220 µA. This part is suitable for applications requiring higher current capacity or where lower forward voltage drop is advantageous. The maximum junction temperature of 150°C matches the original specification. All compliance certifications are maintained.

Frequently Asked Questions (FAQ)

Q: Can the SS36H be used as a direct replacement for the SS36 R6?

A: Yes. The SS36H is a parametric equivalent with identical voltage rating (60 V), current rating (3 A), forward voltage (750 mV @ 3 A), operating temperature range (-55°C to 150°C), and DO-214AB package. Both parts are manufactured by Taiwan Semiconductor Corporation and carry ROHS3 compliance and MSL 1 rating.

Q: What is the difference between the SS36H and CDBC360-G?

A: Both parts share the same 60 V reverse voltage, 3 A current rating, and DO-214AB package. The CDBC360-G has a lower forward voltage (700 mV vs. 750 mV @ 3 A) but a lower maximum junction temperature (125°C vs. 150°C). The CDBC360-G is manufactured by Comchip Technology rather than Taiwan Semiconductor Corporation.

Q: When should the STPS5L60S be selected instead of the SS36H?

A: The STPS5L60S should be selected when the application requires higher current capacity (5 A vs. 3 A) or when lower forward voltage drop is critical to system performance (520 mV @ 5 A vs. 750 mV @ 3 A). The STPS5L60S also provides lower reverse leakage current (220 µA vs. 500 µA @ 60 V). All three parts maintain the same 60 V reverse voltage rating and DO-214AB package.

Q: Are all substitute parts available in the same packaging format?

A: The SS36 R6 is supplied in standard packaging (not specified in available data). The SS36H is supplied in Tape & Reel (TR) format. The CDBC360-G is supplied in Tape & Reel (TR) format. The STPS5L60S is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format differences do not affect electrical compatibility but may impact procurement and assembly processes.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All substitute parts (SS36H, CDBC360-G, and STPS5L60S) are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL 1 (Unlimited) moisture sensitivity rating. The SS36H additionally carries AEC-Q101 automotive qualification.

Q: What is the impact of the lower maximum junction temperature of the CDBC360-G?

A: The CDBC360-G has a maximum junction temperature of 125°C compared to 150°C for the SS36 R6 and SS36H. In applications where the junction temperature approaches or exceeds 125°C under worst-case operating conditions, the CDBC360-G may not be suitable. Thermal analysis of the specific application is required to determine compatibility.

Q: Can the STPS5L60S be used in applications designed for 3 A operation?

A: Yes. The STPS5L60S is rated for 5 A average rectified current, which exceeds the 3 A requirement of the SS36 R6. The part is fully compatible with applications designed for 3 A operation. The higher current rating provides additional design margin and does not create compatibility issues.
