Engineering Selection Recommendations
Parametric Equivalent - Recommended Primary Substitute:
RS3DH (Taiwan Semiconductor Corporation) is the direct parametric equivalent to the discontinued RS3D. This part maintains identical electrical specifications including 200V reverse voltage, 3A average rectified current, 1.3V forward voltage at 3A, and 150ns reverse recovery time. The RS3DH is currently active in production with 3930 pieces in stock. The primary distinction is packaging format (Tape & Reel) and automotive qualification (AEC-Q101 Grade). Both parts comply with RoHS3 standards and feature MSL 1 rating. The RS3DH is suitable for direct replacement in existing designs without performance or reliability concerns.
Direct Manufacturer Equivalent - Secondary Substitutes:
CFRC303-G (Comchip Technology) provides functional equivalence with identical voltage and current ratings, fast recovery speed classification, and 150ns reverse recovery time. This part is active with 689 pieces in stock. The forward voltage specification matches the RS3D at 1.3V @ 3A. Reverse leakage current is lower at 5µA versus 10µA, representing improved performance. Operating temperature range is -55°C to 150°C, matching the RS3D specification.
ER3D-TP (Micro Commercial Co) offers improved performance characteristics with lower forward voltage (0.95V @ 3A) and significantly faster reverse recovery time (35ns versus 150ns). This part is active with 16,840 pieces in stock and operates across an extended temperature range of -50°C to 175°C. The lower reverse leakage current (5µA) and faster recovery characteristics make this suitable for applications requiring improved switching performance.
Similar Functional Equivalent - Tertiary Substitutes:
ES3D-13-F (Diodes Incorporated) meets the core voltage and current requirements with superior performance metrics. Forward voltage is reduced to 0.9V @ 3A, and reverse recovery time is significantly faster at 25ns. This part is widely available with 45,182 pieces in stock. Operating temperature range matches the RS3D at -55°C to 150°C. The improved switching characteristics and high availability make this a practical substitute for new production.
MURS320-13-F (Diodes Incorporated) provides equivalent voltage and current ratings with the lowest forward voltage (0.875V @ 3A) and fastest reverse recovery time (25ns) among all substitutes. This part operates across an extended temperature range of -65°C to 175°C and is active with 7,630 pieces in stock. The superior performance characteristics and extended operating range support applications with demanding thermal or switching requirements.
Package Consideration:
ES3DB-13-F (Diodes Incorporated) is functionally equivalent to ES3D-13-F but uses a DO-214AA (SMB) package instead of DO-214AB (SMC). This part is not a direct substitute for the RS3D due to package incompatibility. Selection of this part requires PCB layout modification and is only appropriate when SMB package footprints are available.
Not Recommended for New Designs:
S3D-TP (Micro Commercial Co) is designated "Not For New Designs" and should not be selected for new production despite meeting voltage and current specifications. This designation indicates the manufacturer has discontinued active support for this product line.
Frequently Asked Questions (FAQ)
Q: Can RS3DH be used as a direct replacement for RS3D without any design modifications?
A: Yes. RS3DH is a parametric equivalent with identical electrical specifications (200V, 3A, 1.3V forward voltage, 150ns recovery time) and the same DO-214AB (SMC) surface mount package. The only differences are packaging format (Tape & Reel) and automotive qualification, neither of which affects electrical compatibility. No PCB or circuit modifications are required.
Q: What is the primary advantage of selecting ER3D-TP or ES3D-13-F over RS3DH?
A: Both ER3D-TP and ES3D-13-F offer significantly faster reverse recovery times (35ns and 25ns respectively versus 150ns for RS3D/RS3DH) and lower forward voltage drops (0.95V and 0.9V respectively versus 1.3V). These improvements reduce switching losses and heat generation, beneficial for high-frequency switching applications. Both parts are currently in active production with high inventory availability.
Q: Why is ES3DB-13-F not recommended as a substitute despite having superior electrical characteristics?
A: ES3DB-13-F uses a DO-214AA (SMB) package, which has a different physical footprint than the DO-214AB (SMC) package required for RS3D. Direct substitution would require PCB redesign and component placement modification. This part is only suitable when SMB package compatibility already exists in the design.
Q: Are all substitute parts RoHS3 compliant and MSL 1 rated?
A: Yes. All substitute parts listed in this reference maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental and handling requirements of the original RS3D specification.
Q: What is the significance of the "Not For New Designs" designation on S3D-TP?
A: This designation indicates that Micro Commercial Co has discontinued active development and support for the S3D product line. While the part may still be available in inventory, the manufacturer does not recommend its use in new designs. Selection of this part creates obsolescence risk for future production requirements.
Q: Can MURS320-13-F be used in applications with operating temperatures below -55°C?
A: Yes. MURS320-13-F operates across a junction temperature range of -65°C to 175°C, extending 10°C lower than the RS3D specification of -55°C to 150°C. This extended range provides additional margin for applications with extreme low-temperature requirements. The part is fully qualified for operation at -65°C.
Q: What is the difference between MURS320-E3/57T and MURS320-E3/9AT?
A: Both parts are manufactured by Vishay General Semiconductor and share identical electrical specifications (200V, 3A, 0.875V forward voltage, 35ns recovery time, -65°C to 175°C operating range). The primary difference is packaging format: MURS320-E3/57T is supplied in Cut Tape (CT) format, while MURS320-E3/9AT is supplied in Tape & Reel (TR) format. Electrical performance and compatibility are identical; selection depends on procurement and assembly requirements.
Q: Is reverse leakage current a critical parameter for substitute selection?
A: Reverse leakage current becomes critical in applications with high reverse voltage stress or extended operating temperatures. The RS3D specifies 10µA @ 200V. Substitutes with lower leakage (5µA) such as CFRC303-G, ER3D-TP, MURS320-13-F, and MURS320-E3/57T provide improved performance in these conditions. For standard applications, the difference is not functionally significant.
Q: Can substitute parts with lower forward voltage reduce circuit power dissipation?
A: Yes. Forward voltage directly affects power dissipation in the diode. Substitutes with lower forward voltage (ES3D-13-F at 0.9V or MURS320-13-F at 0.875V versus RS3D at 1.3V) reduce conduction losses. In high-current applications, this reduction can be significant. However, circuit design must accommodate the lower voltage drop if it affects voltage regulation or biasing networks.
