SL23-M3/5BT Equivalent & Substitute Parts

Part Overview

The SL23-M3/5BT is an active Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 30 V DC reverse voltage with a 2 A average rectified current rating and is packaged in the DO-214AA (SMB) form factor. The device is specified for fast recovery operation with a maximum forward voltage of 500 mV at 2 A and exhibits low reverse leakage current characteristics. Substitute parts are identified to address supply chain requirements, packaging format preferences, or inventory availability while maintaining electrical and mechanical compatibility within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SL23-M3/5BT are qualified based on strict electrical and mechanical parameter equivalence. The substitution criteria are defined by the following parameters:

• Voltage Rating: Voltage - DC Reverse (Vr) (Max) = 30 V
• Current Rating: Current - Average Rectified (Io) = 2 A
• Forward Voltage: Voltage - Forward (Vf) (Max) @ If = 500 mV @ 2 A
• Recovery Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Reverse Leakage: Current - Reverse Leakage @ Vr = 400 µA @ 30 V
• Package Format: DO-214AA (SMB) surface mount
• Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

Substitute parts must satisfy all electrical parameters within the specified ranges and maintain the same physical package format to ensure direct circuit board compatibility. Packaging format variations (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical equivalence but may influence procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

All three diode part numbers—SL23-M3/5BT, SS23-E3/52T, and SS23—are active products with ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. The electrical parameters are identical across all three devices, confirming functional equivalence for 30 V, 2 A Schottky rectifier applications.

SL23-M3/5BT (Vishay, Tape & Reel) and SS23 (Taiwan Semiconductor, Tape & Reel) are suitable for high-volume automated assembly processes requiring continuous reel feeding. Both support the full operating temperature range of -65°C to 125°C.

SS23-E3/52T (Vishay, Cut Tape & Digi-Reel) provides flexibility for mixed-volume production environments and manual assembly operations. This variant maintains the same electrical specifications and temperature range as the SL23-M3/5BT.

The Taiwan Semiconductor SS23 operates within a narrower minimum junction temperature range (-55°C to 125°C) compared to the Vishay variants (-65°C to 125°C). This difference is relevant only for applications requiring operation below -55°C.

Selection between these parts is determined by packaging format requirements, supply chain availability, and minimum operating temperature specifications rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can SS23-E3/52T replace SL23-M3/5BT in a production assembly?

A: Yes. Both devices are manufactured by Vishay and share identical electrical specifications. The primary difference is packaging format: SL23-M3/5BT is supplied in Tape & Reel (TR) format, while SS23-E3/52T is supplied in Cut Tape (CT) & Digi-Reel format. The choice depends on assembly equipment compatibility and procurement preferences.

Q: What is the temperature range difference between Vishay and Taiwan Semiconductor versions?

A: Vishay variants (SL23-M3/5BT and SS23-E3/52T) operate from -65°C to 125°C junction temperature. The Taiwan Semiconductor SS23 operates from -55°C to 125°C. For applications requiring operation below -55°C, Vishay parts are required.

Q: Are all three parts suitable for the same circuit board layout?

A: Yes. All three devices use the DO-214AA (SMB) surface mount package, ensuring identical footprint and pin configuration. No circuit board redesign is necessary when substituting between these parts.

Q: Do packaging format differences affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel packaging formats are handling and delivery methods only. Electrical specifications, performance characteristics, and reliability are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SL23-M3/5BT, SS23-E3/52T, and SS23 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What determines whether a part qualifies as an equivalent substitute?

A: Equivalence is determined by matching all critical electrical parameters: 30 V reverse voltage rating, 2 A average rectified current, 500 mV maximum forward voltage at 2 A, fast recovery speed characteristics, 400 µA reverse leakage current, and DO-214AA surface mount package format. All three listed parts meet these criteria.
