CDSV-19-G Equivalent & Substitute Parts

Part Overview

The CDSV-19-G is a general-purpose rectifier diode manufactured by Comchip Technology, rated for 100V DC reverse voltage and 200mA average rectified current in a surface mount SOD-323 package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or specific packaging format needs.

Substitute Part Grouping Explanation

Substitute parts for the CDSV-19-G are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 200 mA
Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 200 mA
Reverse Recovery Time (trr): 50 ns
Package / Case: SC-76, SOD-323
Mounting Type: Surface Mount
Operating Temperature - Junction: -65°C ~ 150°C
RoHS Status: ROHS3 Compliant

All substitute parts listed maintain these core electrical specifications and package compatibility. Variations in reverse leakage current measurement voltage (100 V vs. 200 V) and junction capacitance do not affect functional equivalence within the specified operating parameters.

Engineering Selection Recommendations

All listed substitute parts maintain electrical equivalence to the CDSV-19-G across the critical parameters: 100V reverse voltage rating, 200mA average rectified current, 1.25V forward voltage drop, and 50ns reverse recovery time. All parts are Active product status and RoHS3 compliant.

Packaging Format Considerations:

CDSV-19-G and BAV19WSHE3-TP are supplied in Tape & Reel (TR) format
BAV19WS-7-F and BAV19WS-TP are supplied in Cut Tape (CT) & Digi-Reel® format

Automotive Applications: BAV19WSHE3-TP includes AEC-Q101 qualification, suitable for automotive-grade applications requiring this certification standard.

Inventory Availability: Substitute parts offer varying inventory levels: BAV19WS-TP (82,241 pcs), BAV19WS-7-F (9,214 pcs), and BAV19WSHE3-TP (4,942 pcs) compared to CDSV-19-G (1,058 pcs).

Frequently Asked Questions (FAQ)

Q: Can BAV19WS-7-F replace CDSV-19-G in all applications?

A: Yes. BAV19WS-7-F meets all electrical specifications: 100V reverse voltage, 200mA current rating, 1.25V forward voltage, and 50ns recovery time. The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Verify your assembly equipment compatibility with the packaging format.

Q: What is the difference between BAV19WS-TP and BAV19WSHE3-TP?

A: Both parts are electrically equivalent to CDSV-19-G. BAV19WSHE3-TP includes AEC-Q101 automotive qualification and is supplied in Tape & Reel format. BAV19WS-TP is standard grade in Cut Tape & Digi-Reel® format. Select BAV19WSHE3-TP for automotive applications requiring AEC-Q101 certification.

Q: Are there differences in reverse leakage current specifications?

A: CDSV-19-G specifies 100nA @ 200V, while substitute parts specify 100nA @ 100V. Both measurements confirm leakage performance within acceptable limits for general-purpose rectifier applications at the rated voltage.

Q: Does junction capacitance variation affect substitution?

A: CDSV-19-G and BAV19WS-7-F specify 5pF @ 0V, 1MHz. BAV19WS-TP and BAV19WSHE3-TP specify 1.5pF @ 0V, 1MHz. Lower capacitance in the latter parts provides improved high-frequency performance but does not prevent substitution in standard rectifier circuits.

Q: Which substitute part should I select for new designs?

A: Selection depends on application requirements: BAV19WS-TP for standard applications with high inventory availability; BAV19WSHE3-TP for automotive applications requiring AEC-Q101 qualification; BAV19WS-7-F for Diodes Incorporated preferred supplier specifications.
