GS1BE-TPS05 Equivalent & Substitute Parts

Part Overview

The GS1BE-TPS05 is a general-purpose rectifier diode rated for 100 V DC reverse voltage and 1 A average rectified current in a surface mount DO-214AC (SMA) package. Manufactured by Micro Commercial Co, this component is classified as Obsolete, indicating it is no longer in active production. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitute parts for the GS1BE-TPS05 are identified based on strict electrical and mechanical parameter matching. The critical parameters that determine substitutability are:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A (or lower)
Speed: Standard Recovery >500ns, > 200mA (Io)
Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters:

Mounting Type: Surface Mount
Package / Case: DO-214AC, SMA

All substitute parts listed meet or exceed these specifications. Parts are grouped into two categories: Direct Manufacturer Substitutes (same base product line from the original manufacturer) and Parametric Equivalents (parts from alternative manufacturers meeting identical electrical and mechanical specifications).

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts directly in place of the GS1BE-TPS05?

A: Yes. All listed substitute parts meet the electrical specifications (100 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage maximum) and use the identical DO-214AC (SMA) surface mount package. Direct pin-to-pin and functional replacement is supported.

Q: What is the difference between parts marked "Active" and "Not For New Designs"?

A: Parts with Active status are currently in production and recommended for new circuit designs. Parts marked "Not For New Designs" are legacy products still available for existing production support but should not be selected for new applications. The GS1BE-TPS05 itself is Obsolete, meaning it is no longer manufactured.

Q: Why do some substitute parts have lower reverse leakage current specifications?

A: Lower reverse leakage current (for example, 1 µA versus 10 µA at 100 V) represents improved performance characteristics. These parts are direct substitutes because they meet or exceed the original specification. Lower leakage current does not create compatibility issues and may provide benefits in low-power applications.

Q: Are there packaging differences among the substitute parts?

A: All substitute parts use the DO-214AC (SMA) surface mount package, ensuring mechanical compatibility. Packaging format differences exist in tape configuration: some are supplied in Tape & Reel (TR), while others are available in Cut Tape (CT) & Digi-Reel format. These differences affect handling and assembly processes but do not affect electrical performance or board-level compatibility.

Q: Which substitute part should I select if I need the highest inventory availability?

A: S1B-E3/5AT (Vishay General Semiconductor - Diodes Division) has the highest inventory with 56,876 units in stock and is an Active product suitable for new designs.

Q: Is the ACGRA4002-HF suitable for automotive applications?

A: Yes. The ACGRA4002-HF is automotive-qualified to AEC-Q101 standard and carries an automotive grade designation. It is suitable for automotive and industrial applications requiring this qualification level.

Q: Do all substitute parts comply with RoHS and REACH regulations?

A: Yes. All substitute parts listed are ROHS3 compliant. Most parts are REACH Unaffected. Compliance documentation is available from individual manufacturers upon request.

Q: What is the operating temperature range for these diodes?

A: All substitute parts operate across a junction temperature range of -55°C to 150°C, matching the original GS1BE-TPS05 specification.
