Equivalent & Substitute Parts for S2DHE3_A/I

Part Overview

The S2DHE3_A/I is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 200 V DC reverse voltage with 1.5 A average rectified current in a DO-214AA (SMB) package. The device is classified as Active product status and carries AEC-Q101 automotive qualification. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to packaging format availability, inventory considerations, or supply chain requirements.

Substitute Part Grouping Explanation

Substitute parts for the S2DHE3_A/I are identified based on strict electrical and mechanical parameter equivalence. All substitute parts share the following critical parameters:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 1.5 A
Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 1.5 A
Reverse Recovery Time (trr): 2 µs
Current - Reverse Leakage @ Vr: 1 µA @ 200 V
Capacitance @ Vr, F: 16 pF @ 4V, 1MHz
Package / Case: DO-214AA, SMB
Operating Temperature - Junction: -55°C to 150°C
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitution is permitted when packaging format differs (Tape & Reel versus Cut Tape) while all electrical characteristics and thermal specifications remain identical. All substitute parts maintain Active product status and are manufactured by the same supplier.

Engineering Selection Recommendations

All three parts—S2DHE3_A/I, S2D-E3/52T, and S2D-E3/5BT—are electrically and mechanically equivalent and maintain Active product status. Selection between these parts is determined by packaging format requirements:

S2DHE3_A/I (Tape & Reel): Primary specification. Use when Tape & Reel packaging is required for automated assembly processes.

S2D-E3/52T (Cut Tape): Substitute when Cut Tape packaging is required for manual assembly, kit builds, or lower-volume applications. Identical electrical performance and compliance certifications.

S2D-E3/5BT (Tape & Reel): Substitute when Tape & Reel packaging is required and S2DHE3_A/I is unavailable. Identical electrical performance and compliance certifications.

All parts carry ROHS3 compliance, REACH Unaffected status, and AEC-Q101 automotive qualification (where applicable). Moisture Sensitivity Level 1 (Unlimited) indicates no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can S2D-E3/52T be used as a direct replacement for S2DHE3_A/I?

A: Yes. S2D-E3/52T is electrically equivalent with identical voltage, current, and thermal specifications. The only difference is packaging format: S2D-E3/52T uses Cut Tape (CT) while S2DHE3_A/I uses Tape & Reel (TR). Selection depends on assembly equipment compatibility.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual assembly or lower-volume applications. Electrical performance is identical.

Q: Are all three parts suitable for automotive applications?

A: All three parts are manufactured by Vishay General Semiconductor - Diodes Division and carry identical compliance certifications including ROHS3 and REACH Unaffected status. Automotive qualification (AEC-Q101) applies to the base product series S2D.

Q: Can these parts be used interchangeably in circuit design?

A: Yes. All three parts share identical electrical parameters: 200 V reverse voltage, 1.5 A average rectified current, 1.15 V forward voltage at 1.5 A, 2 µs reverse recovery time, and -55°C to 150°C operating temperature range. Circuit performance is equivalent.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity. Standard storage and handling procedures apply without special environmental controls.

Q: Are there inventory differences between the three parts?

A: Yes. S2DHE3_A/I has 853 pieces in stock, S2D-E3/52T has 15,100 pieces in stock, and S2D-E3/5BT has 6,490 pieces in stock. Availability may influence selection when supply is constrained.
