HS1FL RVG Equivalent & Substitute Parts

Part Overview

The HS1FL RVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 300 V DC reverse voltage and 1 A average rectified current. This surface mount component operates in the Sub SMA package (DO-219AB) and is classified as an active product with ROHS3 compliance. Substitute parts are identified when equivalent electrical performance is required across different package configurations or when higher voltage ratings are necessary for circuit redesign or component availability optimization.

Substitute Part Grouping Explanation

Substitution of the HS1FL RVG is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

Current rating: 1 A average rectified current (Io)
Speed classification: Fast Recovery ≤ 500ns, > 200mA
Reverse recovery time: 50 ns
Mounting type: Surface Mount
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: MSL 1 (Unlimited)

Secondary Substitution Criteria:

Voltage rating: Equal to or greater than 300 V DC reverse voltage
Forward voltage: Acceptable within circuit design margins
Reverse leakage: Acceptable within circuit design margins
Package compatibility: Physical and electrical footprint compatibility

The HS1GLW RVG qualifies as a substitute part because it maintains the 1 A current rating, fast recovery speed classification, 50 ns reverse recovery time, surface mount configuration, and ROHS3 compliance. The HS1GLW RVG provides a higher voltage rating (400 V) and operates across an extended temperature range (-55°C to 175°C), making it suitable for applications requiring enhanced voltage margin or higher operating temperature capability.

Engineering Selection Recommendations

HS1FL RVG Selection: Select the HS1FL RVG when the application requires a 300 V rated general-purpose rectifier diode in the Sub SMA (DO-219AB) package with a 1 A current rating. This part is active and maintains full ROHS3 compliance with MSL 1 rating, suitable for standard industrial and consumer applications operating within the -55°C to 150°C junction temperature range.

HS1GLW RVG Selection: Select the HS1GLW RVG as a substitute when the application requires enhanced voltage margin (400 V rating) or extended operating temperature capability (-55°C to 175°C). The HS1GLW RVG maintains identical current rating (1 A), fast recovery speed classification, and reverse recovery time (50 ns). This part is active and maintains full ROHS3 compliance with MSL 1 rating. Note that the HS1GLW RVG uses the SOD-123W package, which differs from the Sub SMA package of the HS1FL RVG. Package footprint compatibility must be verified for PCB layout requirements.

Both parts are manufactured by Taiwan Semiconductor Corporation and carry equivalent regulatory compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can the HS1GLW RVG directly replace the HS1FL RVG on a PCB?

A: Electrical substitution is valid based on current rating, speed classification, and reverse recovery time. However, the HS1GLW RVG uses the SOD-123W package while the HS1FL RVG uses the Sub SMA (DO-219AB) package. Physical footprint compatibility must be verified before PCB layout implementation.

Q: What is the primary difference between these two parts?

A: The HS1GLW RVG provides a higher reverse voltage rating (400 V versus 300 V) and extended operating temperature range (-55°C to 175°C versus -55°C to 150°C). Both parts maintain the same 1 A current rating and 50 ns reverse recovery time.

Q: Are both parts RoHS compliant?

A: Yes, both the HS1FL RVG and HS1GLW RVG are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the forward voltage difference between these parts?

A: The HS1FL RVG has a maximum forward voltage of 950 mV at 1 A, while the HS1GLW RVG has a maximum forward voltage of 1.3 V at 1 A. Circuit designs must account for this 350 mV difference in power dissipation and voltage drop calculations.

Q: Can I use the HS1FL RVG in an application designed for 400 V operation?

A: No. The HS1FL RVG is rated for 300 V maximum reverse voltage. Applications requiring 400 V operation must use the HS1GLW RVG or equivalent 400 V rated component.

Q: Are there inventory considerations for these parts?

A: The HS1FL RVG has 974 pieces in stock, while the HS1GLW RVG has 12,232 pieces in stock. Availability may influence component selection for high-volume production.
