Equivalent & Substitute Parts for S07D-M-18

Part Overview

The S07D-M-18 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 200 V DC reverse voltage and 700 mA average rectified current in a surface mount DO-219AB (SMF) package. This component is classified as Active and carries automotive-grade qualification under AEC-Q101. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, packaging preferences, or design flexibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the S07D-M-18 are grouped into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Same Electrical Ratings & Package): Substitute parts that match all critical electrical parameters (200 V reverse voltage, 700 mA average rectified current, 1.1 V forward voltage @ 1 A, 1.8 µs reverse recovery time) and use the identical DO-219AB package. These parts are direct replacements with no circuit redesign required.

Manufacturer Recommended Alternatives (Different Current Ratings or Package): Substitute parts that maintain the 200 V reverse voltage specification but differ in average rectified current capacity, forward voltage characteristics, recovery speed, or package form factor. These alternatives are suitable when circuit requirements permit higher current ratings, different thermal characteristics, or alternative mounting packages. Selection depends on whether the application can accommodate the specific electrical or mechanical differences.

The following key parameters determine substitution eligibility:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 200 V
Current - Average Rectified (Io): Must equal or exceed 700 mA for direct replacement
Package / Case: DO-219AB for direct mechanical compatibility
Mounting Type: Surface Mount
Grade & Qualification: Automotive-grade with AEC-Q101 preferred for consistency

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalents):

S07D-GS08 and S1FLD-GS08 are parametric equivalents to S07D-M-18, offering identical electrical specifications and DO-219AB package compatibility. Both parts are Active status and maintain automotive-grade qualification. S07D-GS08 is available in Tape & Reel packaging with 275,200 units in stock. S1FLD-GS08 is available in Cut Tape & Digi-Reel packaging with 17,100 units in stock. Selection between these two depends on packaging and inventory requirements.

Alternative Selections (Higher Current Capacity):

CRH01(TE85L,Q,M), CRH01(TE85R,Q,M), and UFM13PL-TP provide 1000 mA average rectified current, exceeding the S07D-M-18 specification of 700 mA. These parts maintain 200 V reverse voltage rating and are suitable for applications requiring higher current capacity. CRH01 variants feature 35 ns reverse recovery time (faster than S07D-M-18). UFM13PL-TP offers 35 ns recovery time with 1.0 V forward voltage @ 1 A. All three are Active status. Package form factor is SOD-123F, requiring PCB layout modification from DO-219AB.

Limited Availability Alternative:

BAS21H,115 (Nexperia) is rated for 200 mA average rectified current, below the S07D-M-18 specification. This part is suitable only for applications with reduced current requirements. It features 50 ns reverse recovery time and SOD-123F package. Use is restricted to designs where 200 mA current capacity is sufficient.

Obsolescence Consideration:

SM4003PL-TP carries "Not For New Designs" status and should not be selected for new circuit development, despite meeting electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can S07D-GS08 be used as a direct replacement for S07D-M-18?

A: Yes. S07D-GS08 is a parametric equivalent with identical electrical specifications (200 V, 700 mA, 1.1 V forward voltage, 1.8 µs recovery time) and the same DO-219AB package. No circuit modification is required.

Q: What is the difference between S07D-M-18 and S1FLD-GS08?

A: Both parts are parametric equivalents with identical electrical ratings and DO-219AB package. The primary difference is packaging format: S07D-M-18 and S07D-GS08 are supplied in Tape & Reel, while S1FLD-GS08 is supplied in Cut Tape & Digi-Reel format.

Q: Can CRH01(TE85L,Q,M) replace S07D-M-18 in my circuit?

A: CRH01(TE85L,Q,M) maintains the 200 V reverse voltage rating and exceeds the current requirement with 1000 mA capacity. However, it uses SOD-123F package instead of DO-219AB, requiring PCB layout modification. Forward voltage is lower (0.98 V vs. 1.1 V) and recovery time is faster (35 ns vs. 1.8 µs). Electrical compatibility exists, but mechanical redesign is necessary.

Q: Why is BAS21H,115 listed as a substitute if it only handles 200 mA?

A: BAS21H,115 is listed as a manufacturer-recommended alternative for applications where current requirements do not exceed 200 mA. It is not suitable for circuits requiring the full 700 mA capacity of S07D-M-18.

Q: Should I use SM4003PL-TP for a new design?

A: No. SM4003PL-TP carries "Not For New Designs" product status. Use only for legacy system maintenance or repair of existing equipment. For new designs, select from Active status alternatives: S07D-GS08, S1FLD-GS08, CRH01 variants, or UFM13PL-TP.

Q: What is the impact of package change from DO-219AB to SOD-123F?

A: Package change requires PCB layout modification. DO-219AB (SMF) and SOD-123F are different form factors with different footprints, pad spacing, and thermal characteristics. Mechanical redesign of the PCB assembly is necessary. Electrical performance is not affected by package change alone.

Q: Are all substitute parts automotive-grade?

A: S07D-M-18, S07D-GS08, S1FLD-GS08, BAS21H,115, and CRH01 variants carry automotive-grade qualification. SM4003PL-TP and UFM13PL-TP do not explicitly list automotive-grade designation in the provided specifications. Verify automotive qualification requirements with your design specifications before selection.

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

A: Recovery speed refers to reverse recovery time (trr). Standard Recovery (>500 ns) indicates slower switching behavior. Fast Recovery (≤500 ns) indicates faster switching. CRH01 variants and UFM13PL-TP feature 35 ns recovery time (fast), while S07D-M-18 features 1.8 µs recovery time (standard). Fast recovery reduces switching losses in high-frequency applications.
