SS29L RVG Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS29L RVG is an active Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 90 V DC reverse voltage and 2 A average rectified current in a Sub SMA surface mount package. This component is designed for fast recovery applications with switching speeds of 500 ns or less at currents exceeding 200 mA. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard manufacturing and storage conditions. Substitute parts are identified when equivalent electrical performance parameters are available from the same manufacturer, enabling component interchangeability in circuit designs where package or voltage specifications allow flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS29L RVG is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Technology type (Schottky diode)
• Current rating (2 A average rectified current)
• Forward voltage drop (850 mV @ 2 A)
• Recovery speed (≤ 500 ns, > 200 mA)
• Operating temperature range (-55°C to 150°C)

Mechanical Compatibility Criteria:

• Surface mount mounting type
• Package form factor compatibility

Regulatory Compliance:

• ROHS3 compliance
• MSL 1 rating

The SS210LW substitute part maintains electrical equivalence in current handling, forward voltage characteristics, and recovery speed performance. The substitute operates at a higher reverse voltage rating (100 V versus 90 V), which provides enhanced voltage margin in applications. Package differences between Sub SMA (DO-219AB) and SOD-123W require physical board layout verification but do not affect electrical function.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The SS210LW substitute part is electrically equivalent to the SS29L RVG for applications requiring 2 A rectified current and fast recovery Schottky diode performance. Both parts maintain identical forward voltage characteristics (850 mV @ 2 A) and recovery speed specifications (≤ 500 ns), ensuring functional equivalence in circuit operation.

Voltage Margin Consideration:

The SS210LW operates at 100 V maximum reverse voltage compared to the SS29L RVG at 90 V. This 10 V increase provides additional voltage margin in applications operating near the 90 V specification limit. For circuits designed specifically for 90 V operation, both parts perform identically within the specified voltage range.

Leakage Current Advantage:

The SS210LW exhibits lower reverse leakage current (20 µA @ 100 V) compared to the SS29L RVG (100 µA @ 90 V), resulting in reduced power dissipation in standby or reverse-biased conditions.

Compliance and Reliability:

Both parts carry ROHS3 compliance certification and MSL 1 rating, confirming suitability for standard manufacturing processes and storage conditions. Both maintain identical operating temperature ranges (-55°C to 150°C), supporting equivalent thermal performance.

Package Consideration:

The primary difference between these parts is the package form factor: Sub SMA (DO-219AB) for the SS29L RVG versus SOD-123W for the SS210LW. Physical board layout and footprint compatibility must be verified before substitution. Both packages are surface mount configurations suitable for automated assembly.

Frequently Asked Questions (FAQ)

Q: Can the SS210LW directly replace the SS29L RVG in all applications?

A: Electrical substitution is valid for applications operating at or below 90 V reverse voltage. The SS210LW maintains identical current rating (2 A), forward voltage (850 mV @ 2 A), and recovery speed (≤ 500 ns). Physical package compatibility must be confirmed, as the Sub SMA (DO-219AB) and SOD-123W packages have different footprints.

Q: What is the significance of the higher 100 V rating on the SS210LW?

A: The 100 V rating on the SS210LW provides 10 V additional reverse voltage margin compared to the 90 V SS29L RVG. For circuits designed at 90 V operation, both parts function identically within the specified voltage range. The higher rating does not affect performance in 90 V applications.

Q: Are there differences in leakage current between these parts?

A: Yes. The SS210LW exhibits 20 µA reverse leakage current at 100 V, while the SS29L RVG exhibits 100 µA at 90 V. The lower leakage current in the SS210LW reduces power dissipation in reverse-biased conditions, which may benefit low-power or standby applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SS29L RVG and SS210LW are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. Both carry identical operating temperature specifications (-55°C to 150°C) and are manufactured by Taiwan Semiconductor Corporation.

Q: What must be verified before substituting the SS210LW for the SS29L RVG?

A: Physical board layout compatibility is the primary verification requirement. The Sub SMA (DO-219AB) package used by the SS29L RVG and the SOD-123W package used by the SS210LW have different footprints and pin configurations. PCB layout, solder pad dimensions, and component placement must be confirmed for the SOD-123W package before implementation.

Q: Are the forward voltage characteristics identical between these parts?

A: Yes. Both parts specify 850 mV maximum forward voltage at 2 A, ensuring identical voltage drop performance in forward-biased operation. This equivalence supports direct functional substitution in rectification circuits.

Q: What is the recovery speed specification, and is it identical for both parts?

A: Both parts specify fast recovery of 500 ns or less at currents exceeding 200 mA. This identical specification ensures equivalent switching performance in fast-switching applications and power conversion circuits.
