SMA6J10A-E3/5A Equivalent & Substitute Parts

Part Overview

The SMA6J10A-E3/5A is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates with a 10V reverse standoff voltage and provides 19.6V maximum clamping voltage at peak pulse current. The device is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the same package form factor (DO-214AC/SMA).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMA6J10A-E3/5A is determined by the following critical parameters:

• Reverse Standoff Voltage (Typ): 10V
• Package Form Factor: DO-214AC (SMA surface mount)
• Unidirectional Configuration: Single channel Zener diode
• Voltage Clamping Range: 17V to 21.7V maximum
• Peak Pulse Current Capability: 23.5A to 184A (8/20µs)
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1 (Unlimited)

Substitute parts maintain the 10V reverse standoff voltage specification and DO-214AC package compatibility. Variations in clamping voltage (17V to 21.7V) and peak pulse current (23.5A to 184A) are acceptable within the defined electrical operating window for general purpose TVS applications. All substitute candidates are Active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalent: SMA6J10A-TR (STMicroelectronics) maintains identical reverse standoff voltage (10V), breakdown voltage (11.1V), and clamping voltage (19.6V) specifications. This part is the closest functional match and is Active product status with ROHS3 compliance.

Lower Peak Pulse Current Alternatives: SMAJ10A (MDD), SMAJ10A-13-F (Diodes Incorporated), and SMAJ10A-TP (Micro Commercial Co) operate at the same 10V reverse standoff voltage with reduced peak pulse current (23.5A versus 184A) and lower clamping voltage (17V versus 19.6V). These parts are suitable for applications with lower transient energy requirements. All three are Active product status with ROHS3 compliance.

Automotive Grade Option: SM4T12AY (STMicroelectronics) is qualified to AEC-Q101 automotive standard with 10V reverse standoff voltage. Clamping voltage is elevated to 21.7V with reduced peak pulse current (106A). This part is Active product status with ROHS3 compliance and is appropriate for automotive circuit protection applications.

Temperature Range Considerations: SMA6J10A-TR, SM4T12AY, SMAJ10A-TP, and SMAJ10A-13-F support extended upper operating temperature to 175°C or higher, compared to the main part specification of 150°C. SMAJ10A (MDD) operates to 150°C maximum.

Frequently Asked Questions (FAQ)

Q: Can SMA6J10A-TR be used as a direct replacement for SMA6J10A-E3/5A?

A: Yes. Both parts share identical reverse standoff voltage (10V), breakdown voltage (11.1V), and clamping voltage (19.6V) specifications. Both are packaged in DO-214AC (SMA) surface mount form factor and are ROHS3 compliant. The primary difference is manufacturer (STMicroelectronics versus Vishay).

Q: What is the difference between the 184A peak pulse current parts and the 23.5A parts?

A: Peak pulse current rating indicates the maximum transient current the device can suppress. The SMA6J10A-E3/5A and SMA6J10A-TR are rated for 184A (8/20µs), suitable for high-energy transient suppression. SMAJ10A variants are rated for 23.5A, appropriate for lower-energy transient events. Selection depends on the specific transient energy profile of the protected circuit.

Q: Are all substitute parts in the same DO-214AC package?

A: Yes. All listed substitute parts use the DO-214AC (SMA) surface mount package, ensuring mechanical and footprint compatibility with the original SMA6J10A-E3/5A design.

Q: What does RoHS3 compliance mean for these parts?

A: ROHS3 compliance indicates the parts meet Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specific brominated flame retardants. All listed parts are ROHS3 compliant.

Q: Can SM4T12AY be used in non-automotive applications?

A: Yes. SM4T12AY is qualified to AEC-Q101 automotive standard but is not restricted to automotive use. The automotive qualification indicates additional quality and reliability testing. This part is suitable for general purpose applications requiring the specified electrical characteristics.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has minimal moisture sensitivity and does not require special moisture control during storage, handling, or assembly. All listed parts carry this MSL 1 rating.
