Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS2JA-13 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Technology: Standard

Current Rating Considerations: Substitute parts are grouped into two categories based on average rectified current (Io):

1. 1 A Rated Substitutes – Lower current rating than the original 1.5 A specification. These parts operate within the 600 V voltage class and SMA package but provide reduced current capacity.

2. 1.5 A Rated Substitutes – Direct current rating match to the original RS2JA-13, providing equivalent current handling capability.

3. 2 A Rated Substitutes – Higher current rating than the original specification. These parts provide increased current capacity while maintaining the 600 V voltage class and SMA package compatibility.

Secondary Electrical Parameters: Forward voltage (Vf), reverse recovery time (trr), and reverse leakage current vary among substitutes but remain within acceptable ranges for general-purpose rectification applications at the specified voltage and current levels.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Specifications):

RS2JA-13-F is the direct equivalent to RS2JA-13, manufactured by Diodes Incorporated with identical electrical specifications (600 V, 1.5 A, 1.3 V forward voltage, 250 ns recovery time). The primary distinction is product status: RS2JA-13-F is active and ROHS3 compliant, whereas the original RS2JA-13 is discontinued and RoHS non-compliant. RS2JA-13-F is supplied in Tape & Reel packaging with 30,300 pieces in stock.

1 A Rated Alternatives (Reduced Current Capacity):

For applications where 1 A average rectified current is sufficient, three alternatives are available:

• S1JHE3_A/H (Vishay): Standard recovery speed (>500ns), 1.1 V forward voltage at 1 A, AEC-Q101 automotive qualification. Operating temperature range -55°C to 150°C.

• STTH1L06A (STMicroelectronics): Fast recovery (80 ns), 1.3 V forward voltage at 1 A, maximum junction temperature 175°C.

• US1J-M3/61T (Vishay): Fast recovery (75 ns), 1.7 V forward voltage at 1 A, 10 µA reverse leakage at 600 V.

2 A Rated Alternatives (Increased Current Capacity):

For applications requiring higher current capacity, four alternatives are available:

• STTH2L06A (STMicroelectronics): Fast recovery (85 ns), 1.3 V forward voltage at 2 A, maximum junction temperature 175°C.

• STTH2R06A (STMicroelectronics): Fast recovery (50 ns), 1.7 V forward voltage at 2 A, operating temperature range -40°C to 175°C.

• UG2JA (Taiwan Semiconductor Corporation): Fast recovery (55 ns), 1.3 V forward voltage at 2 A, operating temperature range -55°C to 150°C.

All substitute parts listed are active products with ROHS3 compliance and REACH unaffected status. Selection among alternatives depends on specific application requirements regarding current capacity, forward voltage characteristics, recovery time performance, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RS2JA-13-F be used as a direct replacement for RS2JA-13?

A: Yes. RS2JA-13-F is manufactured by Diodes Incorporated with identical electrical specifications: 600 V reverse voltage, 1.5 A average rectified current, 1.3 V forward voltage at 1.5 A, and 250 ns reverse recovery time. Both use the DO-214AC (SMA) surface mount package. The primary difference is that RS2JA-13-F is an active product with ROHS3 compliance, while RS2JA-13 is discontinued and RoHS non-compliant.

Q: What is the difference between 1 A and 2 A rated substitutes?

A: Current rating indicates the maximum average rectified current the diode can conduct continuously. A 1 A rated diode (S1JHE3_A/H, STTH1L06A, US1J-M3/61T) is suitable for applications requiring up to 1 A. A 2 A rated diode (STTH2L06A, STTH2R06A, UG2JA) is suitable for applications requiring up to 2 A. The original RS2JA-13 is rated for 1.5 A. Selection depends on the actual current requirements of the application.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the DO-214AC (SMA) surface mount package, which is mechanically and electrically compatible with the original RS2JA-13. This ensures direct PCB footprint compatibility without layout modifications.

Q: What does "Fast Recovery" mean compared to "Standard Recovery"?

A: Recovery speed refers to reverse recovery time (trr), the time required for a diode to stop conducting when the applied voltage reverses. Fast recovery diodes (trr ≤ 500ns) switch off more quickly than standard recovery diodes (trr >500ns). The RS2JA-13 has a 250 ns recovery time (fast recovery). Most substitutes maintain fast recovery characteristics, except S1JHE3_A/H which has standard recovery (1800 ns).

Q: Which substitute has the lowest forward voltage drop?

A: S1JHE3_A/H has the lowest forward voltage at 1.1 V @ 1 A. However, this part has a lower current rating (1 A) and standard recovery speed (1800 ns) compared to the original RS2JA-13 (1.5 A, 250 ns). Forward voltage selection depends on application power dissipation requirements.

Q: Which substitute has the fastest recovery time?

A: STTH1R06A has the fastest reverse recovery time at 45 ns, followed by STTH2R06A at 50 ns. These parts are suitable for high-frequency switching applications where minimal reverse recovery time is critical.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original RS2JA-13 is RoHS non-compliant. If RoHS compliance is a design requirement, RS2JA-13-F or any of the listed substitutes satisfy this requirement.

Q: What is the operating temperature range difference?

A: The original RS2JA-13 operates from -65°C to 150°C junction temperature. Substitute parts vary: S1JHE3_A/H and UG2JA operate from -55°C to 150°C; STTH1L06A, STTH1R06A, STTH2L06A, and STTH2R06A have a maximum junction temperature of 175°C (with STTH2R06A specifying -40°C minimum). Selection depends on application temperature requirements.

Q: Can I use a 2 A rated diode in place of a 1.5 A rated diode?

A: Yes. A 2 A rated diode can be used in applications designed for 1.5 A operation. The higher current rating provides additional margin and does not create compatibility issues. However, the application circuit must accommodate any differences in forward voltage and reverse recovery time characteristics.
