BAT43WS-G3-08 Equivalent & Substitute Parts

Part Overview

The BAT43WS-G3-08 is a Schottky diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 30 V DC reverse voltage and 200 mA average rectified current in a surface mount SOD-323 package. This component is classified as a small signal Schottky rectifier diode with a 5 ns reverse recovery time, suitable for high-speed switching applications. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific application qualifications such as automotive-grade certifications.

Substitute Part Grouping Explanation

Substitute parts for the BAT43WS-G3-08 are classified into two categories based on parametric equivalence and manufacturer recommendations:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 30 V reverse voltage rating, 200 mA average rectified current, 450 mV forward voltage at 15 mA, 5 ns reverse recovery time, 500 nA reverse leakage current at 25 V, and 7 pF capacitance at 1 V and 1 MHz. These parts are interchangeable at the circuit level without performance degradation. Parametric equivalents include BAT43WS-E3-08 and BAT43WS-HE3-08, both manufactured by Vishay General Semiconductor - Diodes Division.

Manufacturer Recommended Substitute BAT54WS-7-F from Diodes Incorporated shares the same 30 V reverse voltage rating and SOD-323 package but operates at a reduced average rectified current of 100 mA. This part is suitable for applications where the circuit current requirement does not exceed 100 mA and where cross-manufacturer sourcing is acceptable.

Parameter Comparison

Engineering Selection Recommendations

For Direct Parametric Replacement: BAT43WS-E3-08 and BAT43WS-HE3-08 are fully equivalent to BAT43WS-G3-08 across all electrical and mechanical parameters. Both parts maintain Active product status, RoHS3 compliance, and unlimited moisture sensitivity level. Selection between these two equivalents depends on application requirements: BAT43WS-HE3-08 carries AEC-Q101 automotive qualification and is recommended for automotive applications requiring formal qualification documentation.

For Current-Limited Applications: BAT54WS-7-F from Diodes Incorporated is suitable only when circuit design limits average rectified current to 100 mA or below. This part maintains the 30 V reverse voltage rating, 5 ns reverse recovery time, and SOD-323 package compatibility. The forward voltage specification differs at 1 V @ 100 mA, and reverse leakage current is higher at 2 µA @ 25 V. Operating temperature range extends to 150°C maximum junction temperature, providing broader thermal operating margin compared to the 125°C maximum of the BAT43WS series.

All substitute parts maintain RoHS3 compliance, unlimited moisture sensitivity level (MSL 1), and Active product status, ensuring regulatory and supply chain consistency with the original BAT43WS-G3-08 specification.

Frequently Asked Questions (FAQ)

Q: Can BAT43WS-E3-08 be used as a direct replacement for BAT43WS-G3-08?

A: Yes. BAT43WS-E3-08 is a parametric equivalent with identical electrical specifications: 30 V reverse voltage, 200 mA average rectified current, 450 mV forward voltage at 15 mA, 5 ns reverse recovery time, and 7 pF capacitance. Both parts use the SOD-323 package and maintain the same compliance certifications.

Q: What is the difference between BAT43WS-HE3-08 and BAT43WS-E3-08?

A: BAT43WS-HE3-08 and BAT43WS-E3-08 are electrically identical. The primary distinction is that BAT43WS-HE3-08 carries AEC-Q101 automotive qualification, making it suitable for automotive applications requiring formal qualification documentation. Both parts are manufactured by Vishay and share identical electrical parameters.

Q: Can BAT54WS-7-F replace BAT43WS-G3-08 in all applications?

A: BAT54WS-7-F is suitable only for applications where average rectified current does not exceed 100 mA. The BAT43WS-G3-08 is rated for 200 mA, so BAT54WS-7-F cannot be used in circuits requiring the full 200 mA current capacity. Both parts share the 30 V reverse voltage rating and SOD-323 package.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. BAT43WS-E3-08, BAT43WS-HE3-08, and BAT54WS-7-F are all RoHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the compliance profile of BAT43WS-G3-08.

Q: What is the operating temperature range difference between BAT43WS-G3-08 and BAT54WS-7-F?

A: BAT43WS-G3-08 specifies a maximum junction temperature of 125°C. BAT54WS-7-F from Diodes Incorporated specifies an operating temperature range of -65°C to 150°C, providing a broader thermal operating window with a higher maximum junction temperature of 150°C.

Q: Do all substitute parts use the same SOD-323 package?

A: Yes. BAT43WS-G3-08, BAT43WS-E3-08, BAT43WS-HE3-08, and BAT54WS-7-F all use the SC-76 SOD-323 surface mount package, ensuring mechanical and footprint compatibility on printed circuit boards.

Q: Which substitute part should be selected for automotive applications?

A: BAT43WS-HE3-08 is the appropriate selection for automotive applications, as it carries AEC-Q101 qualification. This part maintains all electrical equivalence to BAT43WS-G3-08 while providing formal automotive qualification documentation.
