Current - Average Rectified (Io): 2 A minimum
Package / Case: DO-214AA (SMB) surface mount
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Secondary Compatibility Parameters:

Operating Temperature - Junction: -55°C minimum to 150°C maximum

This part is suitable for direct substitution in existing HS2D designs without circuit modification.

Similar Substitutes (Electrical Equivalents with Enhanced Performance):

ES2D-13-F (Diodes Incorporated) meets all primary substitution criteria with improved reverse recovery time of 25 ns compared to the HS2D's 50 ns. Forward voltage drop is reduced to 0.92 V at 2 A. This part is available in DO-214AA (SMB) package, ROHS3 compliant, and active status with 130,906 units in stock. The faster recovery time provides enhanced switching performance in rectification circuits.

ES2DHE3_A/H, ES2DHE3_A/I, and ES2DHE3J_A/H (Vishay General Semiconductor - Diodes Division) are automotive-grade alternatives qualified to AEC-Q101. These parts maintain 200 V reverse voltage and 2 A current ratings with improved reverse recovery time of 20 ns. Forward voltage drop is 0.9 V at 2 A. Operating temperature extends to 150°C maximum. These parts are suitable for applications requiring automotive qualification.

Parametric Equivalent (Reduced Current Rating):

HS2D (SURGE) is a parametric equivalent with reduced current rating of 1.5 A compared to the original 2 A specification. This part is suitable for applications with lower current requirements while maintaining 200 V reverse voltage and identical package configuration. Product status is active with 15,200 units in stock.

MURS120-13-F (Diodes Incorporated) is a parametric equivalent with 1 A current rating. This part features improved reverse recovery time of 25 ns and extended operating temperature to 175°C. Forward voltage drop is 0.875 V at 1 A. This part is suitable for lower-current rectification applications.

Package Consideration:

ES2DA-13-F (Diodes Incorporated) is electrically equivalent to ES2D-13-F but packaged in DO-214AC (SMA) surface mount configuration instead of DO-214AA (SMB). This part is not suitable for direct substitution if the PCB layout requires DO-214AA footprint. Selection of this part requires PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can I substitute the HS2D with CURB203-G in my existing design?

A: Yes. CURB203-G is a direct equivalent with identical electrical specifications and DO-214AA (SMB) package. No circuit modification or PCB redesign is required. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between ES2D-13-F and the original HS2D?

A: ES2D-13-F maintains the same 200 V reverse voltage and 2 A current rating but features improved reverse recovery time of 25 ns compared to HS2D's 50 ns. Forward voltage drop is slightly lower at 0.92 V versus 1 V. Both use DO-214AA (SMB) packaging. The faster recovery time provides enhanced switching performance.

Q: Are the Vishay ES2DHE3 series parts suitable for automotive applications?

A: Yes. ES2DHE3_A/H, ES2DHE3_A/I, and ES2DHE3J_A/H are automotive-grade parts qualified to AEC-Q101. These parts meet all electrical requirements of the HS2D with improved reverse recovery time of 20 ns and are suitable for automotive rectification circuits.

Q: Can I use MURS120-13-F as a substitute for HS2D?

A: MURS120-13-F is a parametric equivalent suitable only for applications with reduced current requirements. This part is rated for 1 A average rectified current compared to HS2D's 2 A. If your circuit requires 2 A rectified current, MURS120-13-F is not suitable. For lower-current applications, MURS120-13-F offers improved reverse recovery time of 25 ns and extended operating temperature to 175°C.

Q: What is the difference between ES2D-13-F and ES2DA-13-F?

A: Both parts are electrically identical with 200 V reverse voltage, 2 A current rating, and 25 ns reverse recovery time. The difference is package configuration: ES2D-13-F uses DO-214AA (SMB) while ES2DA-13-F uses DO-214AC (SMA). If your PCB is designed for DO-214AA footprint, use ES2D-13-F. ES2DA-13-F requires PCB redesign.

Q: Why do some substitute parts have lower forward voltage drops?

A: Forward voltage drop variations between 0.875 V and 1 V at rated current are within normal manufacturing tolerances for rectifier diodes. Lower forward voltage drops indicate improved efficiency and reduced power dissipation. Parts with lower Vf values (such as MURS120-13-F at 0.875 V or ES2D-13-F at 0.92 V) generate less heat during operation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original HS2D specifications.

Q: What does reverse recovery time mean and why does it matter?

A: Reverse recovery time (trr) is the time required for a diode to stop conducting when the applied voltage reverses polarity. Shorter reverse recovery times (such as 20-25 ns in substitute parts) indicate faster switching response, reducing switching losses and enabling higher-frequency operation. The original HS2D has 50 ns trr, while improved substitutes offer 20-35 ns.

Q: Can I use ESH2D-E3/52T or ESH2D-E3/5BT if my circuit operates above 150°C?

A: Yes. ESH2D-E3/52T and ESH2D-E3/5BT are rated for junction temperatures up to 175°C, providing 25°C additional thermal margin compared to the HS2D's 150°C maximum. These parts are suitable for high-temperature applications. Both maintain 200 V reverse voltage and 2 A current ratings with improved reverse leakage current of 2 µA at 200 V.
