Part Overview

The RS3KHE3_A/I is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 800 V DC reverse voltage with a 3 A average rectified current rating and is housed in a DO-214AB (SMC) package. The device is classified as Active product status and carries automotive-grade qualification under AEC-Q101 standard. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same package type and performance specifications, ensuring direct functional replacement in circuit applications.

Substitute Part Grouping Explanation

Substitute parts for the RS3KHE3_A/I are identified based on strict electrical and mechanical parameter equivalence. All substitute candidates maintain identical specifications across the following critical parameters: 800 V DC reverse voltage rating, 3 A average rectified current, 1.3 V maximum forward voltage at 2.5 A, 500 ns reverse recovery time, 10 µA reverse leakage current at 800 V, and 34 pF capacitance at 4 V and 1 MHz. All substitute parts utilize the same DO-214AB (SMC) surface mount package and operate across the identical temperature range of -55°C to 150°C junction temperature. Substitution is further validated by matching RoHS3 compliance status, REACH unaffected classification, and standard rectifier diode technology. Packaging format variations (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical or mechanical compatibility and represent alternative distribution methods for the same component.

Engineering Selection Recommendations

All four part numbers—RS3KHE3_A/I, RS3KHE3_A/H, RS3K-E3/57T, and RS3K-E3/9AT—are Active product status and maintain full electrical and mechanical equivalence. RS3KHE3_A/I and RS3KHE3_A/H carry automotive-grade classification with AEC-Q101 qualification, making them suitable for automotive applications requiring formal qualification compliance. RS3K-E3/57T and RS3K-E3/9AT are standard-grade equivalents without automotive qualification but maintain identical electrical performance and RoHS3 compliance for non-automotive applications. Selection between these parts depends on application requirements: automotive designs should prioritize RS3KHE3_A/I or RS3KHE3_A/H, while general industrial applications may utilize RS3K-E3/57T or RS3K-E3/9AT. Packaging format selection (Tape & Reel versus Cut Tape & Digi-Reel) is determined by procurement and assembly process requirements and does not affect component performance.

Frequently Asked Questions (FAQ)

Q: Can RS3K-E3/57T be used as a direct replacement for RS3KHE3_A/I?

A: RS3K-E3/57T is electrically and mechanically equivalent to RS3KHE3_A/I across all specified parameters. However, RS3KHE3_A/I carries automotive-grade qualification (AEC-Q101) while RS3K-E3/57T does not. For automotive applications requiring formal qualification compliance, RS3KHE3_A/I or RS3KHE3_A/H must be used. For non-automotive applications, RS3K-E3/57T provides equivalent performance.

Q: What is the difference between RS3KHE3_A/H and RS3KHE3_A/I?

A: Both parts are automotive-grade, AEC-Q101 qualified, and maintain identical electrical specifications. The difference lies in packaging format designation. Both are suitable for automotive applications requiring qualification compliance.

Q: Are there differences in performance between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: No. Packaging format represents the distribution and handling method only. RS3K-E3/9AT (Cut Tape & Digi-Reel) and RS3K-E3/57T (Tape & Reel) deliver identical electrical and mechanical performance. Selection is based on assembly process compatibility and procurement requirements.

Q: What parameters must remain constant for substitution?

A: Substitution requires equivalence across voltage rating (800 V), current rating (3 A), forward voltage (1.3 V @ 2.5 A), reverse recovery time (500 ns), reverse leakage current (10 µA @ 800 V), capacitance (34 pF @ 4V, 1MHz), package type (DO-214AB, SMC), mounting type (Surface Mount), and operating temperature range (-55°C to 150°C).

Q: Can these parts be used in high-temperature applications?

A: All four parts operate across the junction temperature range of -55°C to 150°C. Applications requiring operation beyond this range require alternative component selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four parts—RS3KHE3_A/I, RS3KHE3_A/H, RS3K-E3/57T, and RS3K-E3/9AT—are ROHS3 compliant and REACH unaffected.
