RS1GL RHG Equivalent & Substitute Parts

Part Overview

The RS1GL RHG is a general-purpose fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400V DC reverse voltage and 800mA average rectified current in a Sub SMA surface mount package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when design requirements permit variations in current rating, package form factor, or recovery speed characteristics while maintaining the same reverse voltage specification and surface mount mounting type. Alternative components may be selected based on availability, packaging format preferences, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RS1GL RHG are classified into two categories based on parametric equivalence and similarity:

Parametric Equivalents maintain identical or superior electrical specifications across all critical parameters: 400V reverse voltage rating, fast recovery speed (≤500ns), 150ns reverse recovery time, 5µA reverse leakage current, and -55°C to 150°C junction temperature range. These parts differ in current rating (800mA to 1A) or package form factor (Sub SMA to SOD-123FL) but remain functionally interchangeable within the specified electrical envelope.

Similar Parts share the same 400V reverse voltage and surface mount DO-219AB package but operate with different recovery characteristics (standard recovery >500ns versus fast recovery ≤500ns), reduced current ratings (700mA), and higher reverse leakage specifications (10µA). These components are suitable for applications where fast recovery performance is not a design requirement.

Key parameters determining substitution eligibility:

• Voltage - DC Reverse (Vr) (Max): 400V (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Reverse Recovery Time: Fast Recovery ≤500ns (for parametric equivalents)
• Operating Temperature Range: -55°C to 150°C (mandatory match)
• RoHS3 Compliance: Required for all substitutes

Parameter Comparison

Engineering Selection Recommendations

RS1GL (SMC Diode Solutions) serves as a parametric equivalent with increased current capacity (1A versus 800mA) while maintaining identical fast recovery characteristics (150ns trr) and forward voltage specifications. This part is suitable for applications requiring higher current headroom within the same 400V rating. Package transition from Sub SMA to SOD-123FL requires PCB layout modification. REACH status is affected for this variant.

RS1GL R3G (Taiwan Semiconductor Corporation) is an identical electrical and mechanical equivalent to the main part RS1GL RHG, differentiated only by packaging format (Tape & Reel versus Cut Tape). This part is directly interchangeable for applications where reel packaging is preferred for automated assembly processes. All electrical parameters, compliance certifications, and temperature ratings remain unchanged.

S07G-GS08 and S07G-GS18 (Vishay General Semiconductor) are similar parts sharing the 400V rating and DO-219AB package but with reduced current capacity (700mA) and standard recovery characteristics (1.8µs trr). These components are suitable for applications where fast recovery performance is not required and lower current ratings are acceptable. Both parts carry AEC-Q101 automotive qualification and are available in higher inventory quantities.

Selection between parametric equivalents and similar parts depends on application-specific requirements for recovery speed, current capacity, and package form factor. All listed parts maintain RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the RS1GL (SMC) with 1A rating replace the RS1GL RHG rated at 800mA?

A: Yes. The RS1GL from SMC Diode Solutions is a parametric equivalent with superior current capacity. The 1A rating provides additional margin for the 800mA application. All other electrical parameters—400V reverse voltage, 150ns reverse recovery time, 1.3V forward voltage, and fast recovery speed—are identical. PCB layout must accommodate the SOD-123FL package instead of Sub SMA.

Q: What is the difference between the RS1GL RHG and RS1GL R3G?

A: These parts are electrically and mechanically identical. The primary difference is packaging format: RS1GL RHG is supplied in Cut Tape format, while RS1GL R3G is supplied in Tape & Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: Can Vishay S07G-GS08 or S07G-GS18 replace the RS1GL RHG in all applications?

A: These Vishay parts share the 400V rating and DO-219AB package but differ in two critical parameters: current rating (700mA versus 800mA) and recovery speed (standard recovery 1.8µs versus fast recovery 150ns). Substitution is valid only for applications where the lower current rating is acceptable and fast recovery performance is not required.

Q: What does "fast recovery" mean and why does it matter?

A: Fast recovery refers to reverse recovery time (trr), the duration required for a diode to transition from forward conduction to reverse blocking. The RS1GL RHG has 150ns trr (fast recovery ≤500ns), while Vishay S07G parts have 1.8µs trr (standard recovery >500ns). Fast recovery reduces switching losses and electromagnetic interference in high-frequency applications. Standard recovery parts are suitable for lower-frequency rectification circuits.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—RS1GL (SMC), RS1GL R3G (TSC), S07G-GS08, and S07G-GS18—are RoHS3 compliant. The main part RS1GL RHG is also RoHS3 compliant. REACH status varies: RS1GL RHG and RS1GL R3G are REACH Unaffected, while RS1GL (SMC) is REACH Affected.

Q: What is the significance of the DO-219AB package designation?

A: DO-219AB is the standardized package outline for Sub SMA and SMF (Surface Mount Form) diodes. The RS1GL RHG, RS1GL R3G, S07G-GS08, and S07G-GS18 all use DO-219AB packages and are mechanically compatible for PCB mounting. The RS1GL (SMC) uses SOD-123F package, which requires different PCB footprint and land pattern.

Q: Can I use the S07G-GS18 instead of S07G-GS08 if both are similar parts?

A: Yes. Both S07G-GS08 and S07G-GS18 are electrically identical with 400V rating, 700mA current, and 1.8µs reverse recovery time. The only difference is reverse leakage current specification: S07G-GS08 specifies 10µA @ 400V, while S07G-GS18 specifies 10µA @ 200V. Both are suitable for the same applications and share identical package, temperature range, and compliance certifications.

Q: What is the operating temperature range for all substitute parts?

A: All parts—main and substitutes—operate across the identical junction temperature range of -55°C to 150°C. This specification is consistent across RS1GL RHG, RS1GL (SMC), RS1GL R3G, S07G-GS08, and S07G-GS18.
