Engineering Selection Recommendations

Direct Equivalent (Full Current Replacement):

The SS2FH6HM3/H is the direct functional equivalent to the SS26L RVG. Both devices maintain identical 60V reverse voltage rating and 2A average rectified current capacity. The SS2FH6HM3/H offers extended operating temperature range (-55 to 175°C versus -55 to 150°C) and includes AEC-Q101 automotive qualification. Forward voltage at rated current is marginally higher (780 mV versus 700 mV), which is within acceptable operating tolerance for most power conversion applications. This substitute is suitable for direct replacement in existing designs without circuit modification.

Reduced Current Alternatives (1A Rating):

The SS1FH6-M3/H and SS1FH6HM3/H are 1A-rated variants suitable only when circuit design permits reduced current capacity. Both maintain the 60V voltage rating and fast recovery characteristics. The SS1FH6HM3/H includes AEC-Q101 automotive qualification, making it appropriate for automotive applications. These substitutes exhibit significantly lower reverse leakage current (3 µA versus 400 µA), which may provide thermal and efficiency benefits in low-current applications. Selection between these two 1A options depends on automotive certification requirements.

Compliance Considerations:

All substitute parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility. The automotive-qualified variants (SS1FH6HM3/H and SS2FH6HM3/H) are mandatory selections for applications subject to automotive industry standards. Standard-grade variants (SS1FH6-M3/H) are appropriate for industrial and consumer applications without automotive requirements.

Frequently Asked Questions (FAQ)

Q: Can the SS1FH6-M3/H or SS1FH6HM3/H (1A rated) be used as direct replacements for the SS26L RVG (2A rated)?

A: These 1A-rated devices are not direct replacements for 2A applications. They are acceptable only when circuit design permits operation at reduced current capacity. The SS26L RVG is rated for 2A average rectified current; substituting a 1A device in a 2A circuit will result in device overstress and potential failure. Verify circuit current requirements before selecting a 1A substitute.

Q: What is the difference between the SS1FH6-M3/H and SS1FH6HM3/H?

A: Both devices are 1A-rated Schottky diodes with identical electrical specifications. The primary distinction is that SS1FH6HM3/H includes AEC-Q101 automotive qualification, while SS1FH6-M3/H is standard-grade. Select the automotive-qualified variant (SS1FH6HM3/H) for applications requiring automotive industry compliance; otherwise, either variant is electrically equivalent.

Q: Is the SS2FH6HM3/H a suitable direct replacement for the SS26L RVG?

A: Yes. The SS2FH6HM3/H maintains identical 60V reverse voltage rating and 2A average rectified current capacity. Both devices are housed in DO-219AB packages and exhibit fast recovery characteristics. The SS2FH6HM3/H offers extended temperature range and AEC-Q101 qualification. Forward voltage is 780 mV at 2A (versus 700 mV for the SS26L RVG), which is within acceptable tolerance for most applications. This substitute requires no circuit modification.

Q: Why do the Vishay substitutes show lower reverse leakage current (3 µA) compared to the SS26L RVG (400 µA)?

A: Reverse leakage current variation is a normal characteristic difference between manufacturers and device families. The lower leakage of Vishay devices may provide thermal efficiency benefits, particularly in applications sensitive to standby power consumption. This difference does not affect forward conduction performance or switching characteristics.

Q: What is the significance of the extended operating temperature range in the Vishay substitutes (-55 to 175°C versus -55 to 150°C)?

A: The extended upper temperature limit (175°C versus 150°C) provides additional thermal margin in high-temperature environments. This is particularly valuable in automotive and industrial applications where junction temperatures approach maximum ratings. The SS2FH6HM3/H and SS1FH6HM3/H are suitable for applications requiring operation at elevated temperatures.

Q: Are all listed substitutes available in the same packaging format as the SS26L RVG?

A: All substitutes use DO-219AB surface mount packages, ensuring mechanical compatibility. However, the SS26L RVG is supplied in Cut Tape (CT) format, while all Vishay substitutes are supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly processes; tape and reel format is standard for high-volume production.

Q: Which substitute should be selected for automotive applications?

A: For automotive applications, select either SS1FH6HM3/H (1A) or SS2FH6HM3/H (2A), both of which carry AEC-Q101 qualification. The choice between 1A and 2A depends on circuit current requirements. The SS1FH6-M3/H lacks automotive qualification and is not suitable for automotive applications.
