TSOD1F1HM RVG Equivalent & Substitute Parts

Part Overview

The TSOD1F1HM RVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 1 A average rectified current in a surface mount SOD-123FL package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs. The substitute identified for this device operates within the same voltage and current ratings while maintaining the same package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSOD1F1HM RVG is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Current - Reverse Leakage @ Vr: 5 µA maximum @ 100 V
• Operating Temperature - Junction: Must encompass or exceed -55°C to 150°C range

Mechanical Compatibility Requirements:

• Package / Case: SOD-123F
• Mounting Type: Surface Mount
• Supplier Device Package: SOD-123FL

The SM4002PL-TP manufactured by Micro Commercial Co meets all electrical and mechanical compatibility criteria for direct substitution with the TSOD1F1HM RVG. Both devices share identical voltage ratings, current ratings, package designation, and mounting methodology.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (TSOD1F1HM RVG): The TSOD1F1HM RVG is the recommended choice for new designs. This component carries Active product status, indicating full manufacturer support and continued availability. It is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. The fast recovery characteristic (≤ 500 ns) provides superior performance in high-frequency switching applications.

Substitute Selection (SM4002PL-TP): The SM4002PL-TP is electrically and mechanically compatible for direct substitution in existing designs or when primary component availability is constrained. However, this component is designated as Not For New Designs by the manufacturer, indicating limited future availability and potential discontinuation. The substitute exhibits standard recovery characteristics (> 500 ns) rather than fast recovery, which may impact performance in applications requiring rapid switching transitions. The substitute maintains equivalent RoHS3 compliance and REACH status. The lower forward voltage drop (1.1 V versus 1.3 V) may provide marginal thermal benefits in power-dissipation-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can SM4002PL-TP be used as a direct replacement for TSOD1F1HM RVG?

A: Yes, SM4002PL-TP is electrically and mechanically compatible for direct substitution. Both devices share identical voltage ratings (100 V), current ratings (1 A), package designation (SOD-123F), and mounting type (Surface Mount). However, the substitute carries Not For New Designs status and exhibits different recovery speed characteristics.

Q: What is the difference between fast recovery and standard recovery diodes?

A: The TSOD1F1HM RVG is classified as fast recovery (≤ 500 ns) with a specified reverse recovery time of 150 ns. The SM4002PL-TP is classified as standard recovery (> 500 ns) with unspecified reverse recovery time. Fast recovery diodes exhibit shorter switching transitions, making them suitable for high-frequency applications. Standard recovery diodes are typically used in lower-frequency applications where switching speed is less critical.

Q: Are both parts RoHS compliant?

A: Yes, both TSOD1F1HM RVG and SM4002PL-TP are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What does "Not For New Designs" mean for the SM4002PL-TP?

A: This designation indicates that the manufacturer does not recommend this component for new product development. It may be subject to discontinuation, limited production, or reduced support. New designs should prioritize the TSOD1F1HM RVG, which carries Active product status.

Q: Is the operating temperature range difference significant?

A: The SM4002PL-TP operates across a wider temperature range (-65°C to 175°C) compared to the TSOD1F1HM RVG (-55°C to 150°C). For applications operating within the TSOD1F1HM RVG range, this difference is not functionally significant. For applications requiring extended temperature operation beyond 150°C, the substitute may provide additional margin.

Q: How does the forward voltage difference affect circuit performance?

A: The SM4002PL-TP exhibits a lower maximum forward voltage drop (1.1 V) compared to the TSOD1F1HM RVG (1.3 V). In power supply and rectification circuits, this 0.2 V difference results in reduced power dissipation and improved efficiency. However, this difference is typically negligible in signal-level applications.

Q: Are both parts available in the same packaging format?

A: Yes, both components are supplied in SOD-123FL surface mount packages. The TSOD1F1HM RVG is available in standard packaging, while the SM4002PL-TP is supplied in Tape & Reel (TR) format. Both are compatible with automated assembly equipment designed for SOD-123F packages.
