SR005HA0G Schottky Diode Equivalent & Substitute Parts

Part Overview

The SR005HA0G is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50V DC reverse voltage and 500mA average rectified current in a DO-204AL (DO-41) through-hole axial package. This component is classified as Active product status with AEC-Q101 automotive qualification and ROHS3 compliance.

Substitute parts are necessary when the SR005HA0G reaches end-of-life status, inventory depletion occurs, or when higher current capacity is required within the same voltage and package specifications. The substitute diodes listed maintain electrical compatibility through matching reverse voltage ratings, fast recovery characteristics, and thermal operating ranges while offering increased current handling capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR005HA0G is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 500 µA @ 50 V
• Package / Case: DO-204AL, DO-41, Axial
• Mounting Type: Through Hole

Allowable Variation Parameters:

• Current - Average Rectified (Io): Substitute parts rated at 1A (1000 mA) exceed the 500 mA requirement and are electrically compatible for applications requiring the SR005HA0G
• Voltage - Forward (Vf) (Max) @ If: Substitute parts with lower forward voltage drop (650 mV @ 1A versus 700 mV @ 500 mA) provide improved performance characteristics
• Operating Temperature - Junction: Substitute parts rated -65°C ~ 150°C extend the lower temperature range beyond the SR005HA0G specification of -55°C ~ 150°C

All substitute parts maintain identical reverse voltage, Schottky technology, fast recovery speed, reverse leakage current, and through-hole axial package configuration as the main part.

Engineering Selection Recommendations

Primary Substitutes (Active Status):

MBR150RLG and SB150-E3/54 and SB150-E3/73 are recommended as primary substitutes for the SR005HA0G. All three parts maintain Active product status, ensuring long-term availability and supply chain stability. MBR150RLG is supplied in Cut Tape (CT) packaging and manufactured by onsemi. SB150-E3/54 and SB150-E3/73 are supplied in Cut Tape (CT) packaging and manufactured by Vishay General Semiconductor - Diodes Division. All three substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the main part.

The Vishay parts (SB150-E3/54 and SB150-E3/73) offer superior forward voltage characteristics at 650 mV @ 1A compared to the onsemi MBR150RLG at 750 mV @ 1A, resulting in lower power dissipation in applications operating at maximum current ratings.

Secondary Substitute (Obsolete Status):

MBR150G is classified as Obsolete product status and should be selected only when primary substitutes are unavailable. While electrically compatible with the SR005HA0G, the obsolete designation indicates limited future availability and potential supply constraints.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the SR005HA0G in automotive and industrial applications. The SR005HA0G carries AEC-Q101 automotive qualification; substitute parts do not list this qualification in the provided data. Applications requiring AEC-Q101 qualification should verify automotive qualification status with the substitute part manufacturer.

Frequently Asked Questions (FAQ)

Q: Can MBR150RLG, SB150-E3/54, or SB150-E3/73 be used as direct replacements for SR005HA0G?

A: Yes. All three substitute parts are electrically compatible with the SR005HA0G. They maintain identical 50V reverse voltage rating, Schottky technology, fast recovery speed characteristics, and reverse leakage current specifications. All parts use the same DO-204AL (DO-41) through-hole axial package and mounting configuration. The substitute parts are rated for 1A average rectified current, which exceeds the SR005HA0G 500mA rating and provides design margin.

Q: What is the difference between MBR150RLG and SB150-E3/54 or SB150-E3/73?

A: The primary difference is forward voltage drop. MBR150RLG (onsemi) is rated at 750 mV @ 1A, while SB150-E3/54 and SB150-E3/73 (Vishay) are rated at 650 mV @ 1A. Lower forward voltage results in reduced power dissipation and heat generation during operation. Both manufacturers' parts are Active status with identical voltage and current ratings. Selection between these options depends on thermal management requirements and power efficiency priorities.

Q: Why do substitute parts have higher current ratings (1A) than the SR005HA0G (500mA)?

A: Higher current ratings in substitute parts provide design margin and allow the same physical package to handle increased current loads. The 1A rating does not require the application to operate at maximum current; the diode functions correctly at any current level up to its rated maximum. Applications designed for 500mA operation with the SR005HA0G will operate identically with 1A-rated substitutes.

Q: Are all substitute parts suitable for automotive applications?

A: The SR005HA0G carries AEC-Q101 automotive qualification. The provided data does not list AEC-Q101 qualification for substitute parts. Applications requiring automotive qualification should verify this certification status with the substitute part manufacturer before selection.

Q: What is the difference between Cut Tape (CT) and other packaging formats?

A: Cut Tape (CT) is a standard reel packaging format for through-hole components. The SR005HA0G data does not specify packaging format, while MBR150RLG, SB150-E3/54, and SB150-E3/73 are supplied in Cut Tape format. Both packaging formats contain identical components; the difference is in supply reel configuration and quantity per reel. Cut Tape packaging is standard for high-volume production environments.

Q: Why is MBR150G listed as Obsolete?

A: MBR150G is classified as Obsolete product status by the manufacturer, indicating that production has been discontinued. While electrically compatible with the SR005HA0G, obsolete parts have limited remaining inventory and no guarantee of future availability. MBR150G should be selected only when Active alternatives are unavailable.

Q: Can substitute parts operate at the SR005HA0G temperature range of -55°C to 150°C?

A: Yes. All substitute parts are rated for -65°C to 150°C operating temperature range, which extends below the SR005HA0G minimum of -55°C. This extended range ensures compatibility across the full SR005HA0G operating temperature specification and provides additional margin for extreme cold environments.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts (MBR150RLG, MBR150G, SB150-E3/54, and SB150-E3/73) are ROHS3 compliant and REACH unaffected, matching the compliance status of the SR005HA0G. This ensures regulatory compatibility in applications subject to RoHS and REACH requirements.
