The SS26L RVG is a parametric equivalent with identical electrical and mechanical specifications, differing only in packaging format (Cut Tape versus reel configuration).

The Vishay parts SS1FH6-M3/H and SS1FH6HM3/H are similar substitutes with reduced current rating (1 A versus 2 A) and lower reverse leakage current (3 µA versus 400 µA). These parts are suitable for applications where the 2 A current requirement is not mandatory.

The Vishay part SS2FH6HM3/H is a similar substitute with matching 2 A current rating and automotive-grade qualification (AEC-Q101), with forward voltage of 780 mV @ 2 A and extended junction temperature range to 175°C.

Engineering Selection Recommendations

SS26L RVG is the direct parametric equivalent to SS26L RQG. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications, reverse voltage rating, current capacity, and forward voltage characteristics. The only distinction is packaging format: SS26L RVG is supplied in Cut Tape (CT) format while SS26L RQG is supplied in standard reel configuration. Selection between these two parts depends on assembly process requirements and tape handling capabilities. Both maintain RoHS3 compliance and identical thermal operating ranges.

SS1FH6-M3/H and SS1FH6HM3/H are similar substitutes manufactured by Vishay General Semiconductor - Diodes Division. These parts share the 60 V reverse voltage rating and DO-219AB package with the main part. However, the current rating is reduced to 1 A, making these suitable only for applications where the 2 A current requirement is not mandatory. Both parts feature significantly lower reverse leakage current (3 µA versus 400 µA) and extended junction temperature range to 175°C. The SS1FH6HM3/H carries automotive-grade qualification (AEC-Q101), while SS1FH6-M3/H is standard industrial grade. Selection of these parts requires confirmation that circuit design can operate within the 1 A current limit.

SS2FH6HM3/H is a similar substitute manufactured by Vishay General Semiconductor - Diodes Division with matching 2 A current rating and 60 V reverse voltage. This part is automotive-grade qualified (AEC-Q101) and features extended junction temperature range to 175°C. Forward voltage is specified at 780 mV @ 2 A, compared to 700 mV @ 2 A for the main part. Reverse leakage current is significantly lower at 3 µA versus 400 µA. This part is suitable for applications requiring automotive qualification or extended thermal performance. The forward voltage differential of 80 mV must be evaluated for circuit impact.

All substitute parts maintain RoHS3 compliance, Schottky technology, fast recovery characteristics, and surface mount DO-219AB package compatibility with the SS26L RQG.

Frequently Asked Questions (FAQ)

Q: Can SS26L RVG be used as a direct replacement for SS26L RQG?

A: Yes. SS26L RVG is a parametric equivalent with identical electrical specifications, reverse voltage, current rating, forward voltage, and thermal operating range. The parts differ only in packaging format (Cut Tape versus reel). Direct substitution is supported provided the assembly process accommodates the tape format.

Q: What is the difference between SS26L RQG and the Vishay SS1FH6-M3/H?

A: The primary difference is current rating: SS26L RQG is rated for 2 A average rectified current, while SS1FH6-M3/H is rated for 1 A. Both share the 60 V reverse voltage rating and DO-219AB package. SS1FH6-M3/H features lower reverse leakage current (3 µA versus 400 µA) and extended junction temperature range (-55°C to 175°C versus -55°C to 150°C). Substitution is valid only if circuit design operates within the 1 A current limit.

Q: Is SS2FH6HM3/H a suitable replacement for SS26L RQG?

A: SS2FH6HM3/H is a similar substitute with matching 2 A current rating and 60 V reverse voltage. Both parts use the DO-219AB package and Schottky technology. Key differences include forward voltage (780 mV @ 2 A versus 700 mV @ 2 A), reverse leakage current (3 µA versus 400 µA), and automotive-grade qualification (AEC-Q101). The 80 mV forward voltage difference must be evaluated for circuit impact. Extended junction temperature range to 175°C is available with this part.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive-grade qualification standard. Parts carrying this qualification (SS1FH6HM3/H and SS2FH6HM3/H) are qualified for automotive applications and undergo additional reliability testing. This qualification is not present on SS26L RQG or SS26L RVG, which are industrial-grade components.

Q: Can I use a 1 A rated diode in place of a 2 A rated diode?

A: Substitution of a lower current-rated part (1 A) for a higher current-rated part (2 A) is valid only if circuit design analysis confirms that actual operating current does not exceed the lower rating. The 1 A parts (SS1FH6-M3/H and SS1FH6HM3/H) cannot be used in applications requiring sustained 2 A operation.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current affects power dissipation and circuit performance at reverse bias conditions. SS26L RQG specifies 400 µA @ 60 V, while Vishay substitutes specify 3 µA @ 60 V. Lower leakage current reduces standby power consumption and heat generation. Applications sensitive to leakage current performance should account for this 133-fold difference.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. SS26L RQG, SS26L RVG, SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H are all RoHS3 compliant. All parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the difference between Cut Tape and standard reel packaging?

A: Cut Tape (CT) packaging, used for SS26L RVG, provides components on tape that is cut into individual strips for handling. Standard reel packaging, used for SS26L RQG, provides continuous tape on a reel. Selection depends on assembly equipment capability and process requirements. Both formats contain identical components.
