B0530WS-7-G Equivalent & Substitute Parts

Part Overview

The B0530WS-7-G is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 30 V DC reverse voltage and 500 mA average rectified current in a surface mount SOD-323 package. This part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain identical electrical performance characteristics and package compatibility while offering active product status and continued availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the B0530WS-7-G is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 500 mA
• Voltage - Forward (Vf) (Max) @ If: 450 mV @ 500 mA
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Current - Reverse Leakage @ Vr: 500 µA @ 30 V
• Capacitance @ Vr, F: 58 pF @ 0 V, 1 MHz
• Package / Case: SC-76, SOD-323
• Operating Temperature - Junction: -40°C ~ 125°C
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain complete parametric equivalence across these criteria. Differences in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and product status (Active versus Obsolete) do not affect electrical or mechanical compatibility. Automotive-grade variants with AEC-Q101 qualification provide additional certification for applications requiring automotive compliance.

Parameter Comparison

Engineering Selection Recommendations

B0530WS-7-F is the direct functional equivalent with active product status. This part maintains all electrical and mechanical specifications of the B0530WS-7-G while offering continued manufacturing support and availability. The packaging format is Cut Tape & Digi-Reel®, suitable for standard production environments.

B0530WSQ-7-F and B0530WSQ-13-F are automotive-grade alternatives qualified to AEC-Q101 standard. These parts are appropriate for applications requiring automotive compliance certification. Both maintain identical electrical performance and SOD-323 package specifications. The primary distinction between these two automotive variants is the packaging format: B0530WSQ-7-F uses Tape & Reel (TR) with 7-inch reel configuration, while B0530WSQ-13-F uses Tape & Reel (TR) with 13-inch reel configuration.

Selection between standard-grade B0530WS-7-F and automotive-grade B0530WSQ variants depends on application requirements and compliance mandates. All three substitute parts are electrically and mechanically interchangeable with the obsolete B0530WS-7-G.

Frequently Asked Questions (FAQ)

Q: Can B0530WS-7-F directly replace B0530WS-7-G in existing designs?

A: Yes. B0530WS-7-F is a parametric equivalent with identical electrical specifications, forward voltage characteristics, reverse leakage, capacitance, and operating temperature range. The SOD-323 package and surface mount configuration are identical. The primary difference is product status: B0530WS-7-F is active while B0530WS-7-G is obsolete.

Q: What is the difference between B0530WSQ-7-F and B0530WSQ-13-F?

A: Both parts are electrically and mechanically identical. The difference is packaging format: B0530WSQ-7-F is supplied on 7-inch reels, while B0530WSQ-13-F is supplied on 13-inch reels. Selection depends on production volume and tape reel handling requirements.

Q: Are the automotive-grade variants (B0530WSQ series) suitable for non-automotive applications?

A: Yes. Automotive-grade parts with AEC-Q101 qualification meet or exceed standard-grade specifications. They are fully compatible with non-automotive applications and provide additional reliability certification.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) affects only supply and handling logistics. Electrical performance, thermal characteristics, and mechanical compatibility remain identical across all substitute parts.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. B0530WS-7-F, B0530WSQ-7-F, and B0530WSQ-13-F are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the B0530WS-7-G.

Q: What is the reverse voltage rating, and can these diodes be used in higher voltage applications?

A: The reverse voltage rating is 30 V maximum. These diodes are not suitable for applications exceeding 30 V DC reverse voltage. Alternative diode selections with higher voltage ratings are required for higher voltage applications.

Q: Is the 500 mA current rating the maximum continuous current?

A: The 500 mA specification represents the average rectified current (Io). Operating conditions, thermal management, and duty cycle must be evaluated to ensure the diode operates within safe limits for specific applications.
